Construction activity, method or technique consumes large amount of energy, first in form of non-renewable resources like material at time of construction and secondly at post construction period in the form of operation energy. One of the major component responsible for enhancing material demand is roof .non reflective roof absorbs and retains solar energy as heat, which contributes not only to hotter roof, but also uneven thermal expansion / contraction of the roof. Creating either discomfort for the building inhabitants or increased local cooling loads. This increased absorption of solar energy by present concrete roofing system is causing heat island effect. Researchers found that city is warmer than the surroundings remote or village areas. The average temperature in large cities can range from 5 to 10 o c warmer. , this phenomenon, know as the urban heat island effect. As thermal conductivity of concrete is high as compared to other materials, the amount of thermal flux or heat transfer further increases demand for consumption of operational energy in form of fan, air cooling devices etc. Thus, to make living environment sustainable, alternative techniques should be adopted. The experimental work done over here is to check out the feasible usage of green roof concept in construction methodology, by creating model and finding out cooling effect of green roof as compared to other roofing system and further thermal analysis is done by process of simulation using Ansys Fluent Flotran. This experimental work lead to following benefits:- Reduce in heat transfer rate and thus thermal flux below roof.,Overall reduction in room temperature in day time.Reduction in material consumption, i.e resources.Environmental friendly construction techniqueReduction in operation energy consumption of house & thus making living environment healthy and economical for inhabitants.

A green building is an environmentally sustainable building, designed, constructed and operated to minimise the total environmental impacts. Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. It is claimed that 5% of the world’s carbon dioxide emission is attributed to cement industry, which is the vital constituent of concrete. Due to the significant contribution to the environmental pollution, there is a need for finding an optimal solution along with satisfying the civil construction needs. Apart from normal concrete bricks, a clay brick, Foam concrete is a new innovative technology for sustainable building and civil construction which fulfills the criteria of being a Green Material. This paper concludes that Foam Concrete can be an effective sustainable material for construction and also focuses on the cost effectiveness in using Foam Concrete as a building material in replacement with Clay Brick or other bricks.
An artificial neural network (ANN), usually called neural network (NN) consists of mathematical model or computational model that is inspired by the structure and/or functional aspects of biological neural networks. Modern neural networks are non linear statistical modeling tools. They are usually used to model complex relationships between inputs and outputs or to find patterns in data. The bend of channel varies according to its radius, degree of angle at its curvature and depth at different sections of channel due to which the velocity of the flow of water at the bend of channel vary at different sections. Hence it is necessary to study and predict the velocity for planning and management of water resources. In this regard, prediction of velocity at a bend of channel was studied using experimental setup of flume and thus various experiments were conducted, The observations were recorded and data regarding varied radius, depth ,theta were collected and from this velocity was measured. In this regard prediction of velocity was done using artificial neural network with components in channel bend i.e. angel of bend, radius of bend, flow depth and Karmans constant as input data except Karmans constant, while the velocity as a target output, The total no. of samples recorded are 315. It was observed that different methods were used such as MLP, recurrent networks etc for prediction of parameters of hydrology but the method of Fuzzy Logic was never applied while using ANN. Hence depending on the data representation and the application the model Fuzzy logic is used to train and learn the data sets. Hence after training for number of runs, learning and testing the results obtained were satisfactory. Supervised neural networks that use an MSE cost function can use formal statistical methods to determine the confidence of the trained model. The MSE on a validation set can be used as an estimate for variance. This value can then be used to calculate the confidence interval of the output of the network, assuming a normal distribution. The results of the study showed that predictions of velocity using artificial neural network are reasonable, suitable and of acceptable accuracy. Hence prediction of velocity at the curvature of channel by ANN may be useful for water quality planning and management.

In this experimental work, an approach has been made to determine the feasibility of recycled aggregate in the concrete. For that purpose two water cement ratios are chosen for making concrete mix of same characteristic strength. Again, to determine the effect of recycled aggregate on the strength, the percentage of the recycled is adjusted with 10%, 20%, 30%, 50% and 100%. It was found that with addition of recycled aggregate the concrete strength and workability decrease, to improve the strength and the workability, the flyash is added at the rate of 10% and 20% as replacement of PPC. The compressive strength of concrete is determined, after curing periods of 7, 28 and 90 days. To establish an empirical relationship between the strength of concrete and four variable parameters (i.e. percentage of RCA, percentage of flyash, curing age and water-cement ratio), two modeling methods were used namely to develop the mathematical model by Multi-linear Regression Method and to develop the Neural Network model by Artificial Neural Networking Method. The test results show that 90 days strength of mix RAC20+F10 is almost nearly greater or equal to strength of NAC based concrete. The compressive strength of 90 days, of the above mix was found to be 3.92% more than the natural aggregate based concrete on average. On the other hand, when water cement ratio is decreased, the 90 days compressive strength was found to be 2.97% for 7% decrement in water-cement ratio.

Most State highways in the central part of India (e.g., Maharashtra State) have problems of foundation due to presence of highly compressible clayey soils (mostly black cotton soil). The sub grade soil and its properties are important in the design of pavement structure. It has been the common observation and experience that the pavements of highways and roadways constructed either on in situ soil formations or on compacted black cotton soil embankment show several types of damages to pavement structures, and in many instances the pavements may even become unserviceable because of highly deteriorated conditions of the whole pavement system. The present work is aimed to assess the improvement in the strength and stability characteristics in soft Subgrade soil by using the fly ash for the stabilization and then Nylon fibre as reinforcing material. Randomly distributed fibre reinforced soil (RDFRS) technique is used to prepare the reinforced soil samples. In RDFRS technique the mixing of reinforcement in the soil is very easy and no special skill is required. The reinforcement is added by percentage of the weight of the soil sample and by following certain aspect ratio i.e., length/diameter (L/D) ratio. Attempt is made to determine optimum combination of fly ash and fiber content for maximum gain in strength.

An experimental investigation was conducted on self compacting concrete with different percentages of coarse recycled concrete aggregate. The main objective was to study suitability and effect of coarse recycled aggregate in new generation concretes. In the recent years the demand for construction materials has grown tremendously, so has the amount of construction and demolition waste, putting huge pressure on the environment. This has encouraged the use of recycled aggregate in concrete which not only allows for a more efficient life cycle of natural resources but also contributes to environmental protection leading to sustainable development. In this study coarse recycled aggregate (RCA) are used in the production of self compacting concrete (SCC) in varying percentage replacements of natural coarse aggregate (NCA) from 0% to 100% with increment of 20%. The various test performed were compressive strength, split tension test, water absorption, acid attack and chloride ingress. It is observed that up to 40% recycled aggregate can be effectively used in the production of SCC without any significant reduction in strength and durability.

In this paper, the shear strength of plastic (PET) fiber reinforced concrete (PFRC) is discussed. The post-consumer PET mineral bottles were manually cut into fiber form after removing neck and bottom, and these fibers were used to reinforce the plain concrete. The concrete of M20 and M30 grades were selected for the study. The PET fibers were obtained from used mineral water bottles, without any processing, of two sizes with aspect ratios 35 and 50. The fibers were added in proportions 0.0 % to 3.0 % at an increment of 0.5%. The concrete specimens were tested after 28 days of curing. The shear resistance of plastic fiber reinforced concrete (PFRC) was found to be increased. The maximum increased in shear strength of PFRC was 27.25% for M20 grade of concrete at 1% fiber volume fraction with aspect ratio 50, over the normal concrete. A model for predicting the shear strength for PFRC is presented, based on the experimental results, in terms of cube compressive strength and fiber volume fraction.

Need for sustainable development has demanded the utilization of wastes from various industries in all possible applications. Sugarcane bagasse ash is one of such wastes available in huge quantity and has found to have pozzolanic characteristics. The amorphous silica in sugarcane bagasse ash comes into play when it is produced in controlled conditions, hence study was carried out to justify the pozzolanic behaviour of bagasse ash obtained from local sugar industry near Pandharpur. Present paper deals with study on effect of partial replacement of cement by sugarcane bagasse ash on the compressive strength of M20 grade of concrete. The cement was partial replaced by SCBA in the percentage of 0, 5, 10, 15, 20, 25 and 30% by weight of cement and it was observed that 20% replacement of cement by SCBA has no negative effect on compressive strength of concrete. Hence 20% replacement of cement by SCBA will result in economical production of concrete.

In new era of construction of multi-storied buildings with open ground storey is a common practice in India provided for functional and architectural reasons. Though calamitous collapse of R/C building having soft storey at ground floor is an age old Phenomenon. However nothing promising has been done to retrofit them. This may be primarily due to high cost of retrofitting techniques, which are in practice today. The main intend of this study is to demonstrate that addition of in filled walls in ground floor and strengthening of other in fill panels in typical low rise R/C building having soft storey at ground floor, provides an alternative cost-effective and perhaps most convenient retrofit solution.

Water is one of the basic needs having vital importance for the survival of human being. Environment fulfils this need of human being by providing different natural resources like rivers, lakes, streams etc. This need of human being demands for clean water for drinking and recreation purpose but now-a-days, due to the reasons like increased population, urbanization & industrialization are getting polluting these natural resources. As the demand for water increases, making more efficient use of water becomes more important. River Mutha as it passes through the city of Pune receives domestic waste as well as industrial waste. Untreated or partially treated wastewater, which is a negative externality of urban water use, is widely used for irrigation in water scarce regions like Purandar, Daund, Haweli, and Baramati having undulating ground profile where average rainfall is around 400 to 500 mm. Marginal quality water or water whose quality might pose a threat to sustainable agriculture and/or human health if used for irrigation without taking certain precautions. In order to protect the public both from consuming crops grown on contaminated water and from direct exposure to the applied effluent during ploughing etc. The waste water needs to be treated properly before it is supplied for irrigation. Low cost technology (oxidation pond) is particularly well suited for tropical and subtropical regions because the greater amount of sun and higher temp contribute to a more efficient removal of waste as well as system provide reliable, low cost, and relatively low maintenance treatment for municipal and industrial discharges.

The growing rate of delays is adversely affecting the timely delivery of construction projects. For owner, delay means the loss of income and unavailability of facilities. For contractor, delay means the loss of money for extra spending on equipment and materials and hiring the labor and loss of time. They are almost always accompanied by cost and time overruns. Construction project delays have a debilitating effect on parties such as owner, contractor, and consultant in terms of a growth in adversarial relationships, distrust, litigation, arbitration, cash-flow problems etc. Construction delay has become endemic in Indian construction industry. Delay of a project is a main factor and the major cause of construction claims. Therefore there is acute necessity for a detailed analysis of the delay factors and chooses correct actions to minimize the adverse effect of delay on time, within cost and for high quality.

The use of fly ash as a cement replacement makes the mortar less permeable to harmful ions due to its finer particle size distribution and pozzolanic reactions. This results in an enhanced high performance and more durable mortar. Number of studies of the effects of the fly ashes on the behaviour of cement pastes, mortars, and concretes were also carried out. Paper has examined the effect of fly ash used as replacement addition to the Ordinary Portland cement (OPC) on the compressive strength development of cement mortars of five hopper fly ashes at Khaperkheda Thermal Power Plant. The mix proportion 1:3 of cement mortar in which cement is partially replace with fly ash as 0%, 12.5%, 25% and 37.5% by the weight of cement. Compressive strengths of the mortar specimens were determined at 7, 28, and 90 days. Test results show that strength increases with the increase of fly ash up to an optimum value, beyond which, strength values start decreasing with further addition of fly ash.

Turbo Generator consists of turbine and generator. It is used for generating Electricity. It is a very heavy machine, inducing large forces due to its self weight & operation on foundation.The Turbo Generator foundation is a vital & expensive part in a power plant complex. It is therefore essential that the foundation is designed adequately for all possible combinations of static and dynamic loads. It is a task of the structural designer to check the adequacy of the foundation under static and dynamic condition. At times it may becomes necessary to suitaibly alter the dimensions of the foundation as suggested by machine manufacturer so as to satisfy the design requirements.Any alterations thus found necessary must however have the prior concurrence of the Mechanical Engineer to ensure that these changes do not affect the erection operation of the machine.It is desirable therefore to have a close coordination between the foundation designer and the erection staff from the early planning stage until the foundation is completed and the machine is installed.

The effective coordination has been regarded in both theory and practice as a critical factor of success in construction projects. Therefore this study is carried out, for studying the actual coordination methods adopted by the contractors at construction site. Previous coordination studies have focused on the time spent on coordination, its frequency, and its relationship with performance. However, coordination goals have received less attention, and their relationships with coordination methods and performance are not known. To achieve objective of this study, a questionnaire was designed accordingly and sent to five project manager for survey. Follow-up interviews were conducted with one to two engineers from each project. It was difficult to investigate goals in this study without quantifying goal priorities. Assumptions made in quantifying the priorities of goals are examined here. The top three goals were scored 3, 2, and 1, respectively. The average percentage of goal achievement of different coordination methods is also found out to identify the better coordination method for all five construction projects. In this way percentage goal achievement and respective goal replacement possibility is calculated. The charts are prepared on the basis of data collected; from this best company using effective coordination method is observed.

Homogenous charge Combustion ignition (HCCI) engines are being considered as an alternative to diesel engines. The HCCI concept involves premixing fuel and air prior to induction in to the cylinder (as is done in current spark- ignition engine) then igniting the fuel –air mixture through the compression process ( as is done in current diesel engines). The combustion occurring in HCCI engine is fundamentally different from a spark ignition and Diesel engines in that of heat release occurs as a global auto ignition process, as opposed to the turbulent flame propagation or mixing controlled combustion used in current engines . The advantage of this global auto ignition is that the temperature within the cylinder are uniformly low, yielding very low emission of oxides of Nitrogen( NOx, the chief precursors to photochemical smog). The inherent feature of HCCI combustion allows for design of engines with efficiency comparable to, or potentially higher than, diesel engines. This paper describes the results & Strategy proposed to control the combustion of HCCI engine. This is achieved by controlling air path & fuel path to maintain start of Combustion. An experimental results of Combustion Control analysis are presented to prove the strategy used for these experiments.

In today’s era of escalating energy cost, vegetable oils provide a technically as well as economically viable substitute to diesel oils for use in automobile as well as stationary engines. Alternate fuels have the great potential to supplement the growing demands for conventional petroleum fuels. The main alternative fuel of significance in the present and near future may be bio fuels or bio diesel. Bio-diesel is an efficient, clean 100% natural energy alternative to petroleum fuels. It is a renewable substitute or blending stock, currently being commercialized in United States and Europe. Bio-diesel operate in C.I. engines similar to diesel fuels. It can be burnt in any standard unmodified diesel engine blended with 25% to 100% bio-diesel with diesel. Cottonseed oil can be converted into bio-diesel fuel as ethyl fuel as ethyl ester by transesterification. Cottonseed oil methyl ester was prepared which showed density, calorific value, flash point, and pour point close to that of diesel oil. The blends of varying proportions of this bio-diesels and diesel were used to run a single cylinder compression ignition engine and significant improvement in engine performance and emission characteristics were observed.
The fill medium in the cooling tower which provides the surface for heat transfer,isa key factor in the performance of cooling tower.Currently used fill is made from PVC corrugated sheets with passages for air. It suffers from the limitations of scaling and more resistance to the flow of air. The range of cooling tower is 6 to 12°Cand approach of the order of 5 to 6°C. If we achieve a greater range and closure approach to wbt, the operating cost on pumping water can be considerably reduced. The reduction in resistance to air flow will save the operating cost on fan. This work is an attempt to develop the cooling tower with more porous nature of fill and without using any type of draught. The fill medium is a stretched nylon net in zigzag pattern arranged vertically in numbers. The trials conducted on cooling tower without draught gives the range of 6°C and approach of 11°C for hot water temperature of 35°C. Thus the nylon net arranged in zigzag pattern can be used as the fill medium for cooling tower with better performance. Proper combination of size of zigzag net, density of fill and height of fill has to be worked out.

Electrical discharge machining is one of the earliest non-traditional machining processes. It is based on thermoelectric energy between the workpiece and a tool electrode. A pulse discharge occurs in a small gap between the workpiece and the tool electrode and it removes the unwanted material from the base metal through melting and evaporating. To generate the spark the workpiece and electrode the must have electrical conductivity. There are various type of product which can be produced using EDM such as dies and moulds. Parts of automobile industry, surgical components and aerospace can be finished by EDM. This paper reviews the recent research trends in EDM on effects of different tool geometry on performance measure in EDM and different electrode material. The final part of the paper discusses these developments and outlines the trends for future research work.

With the ever – increasing prices of gasoline, the diesel engines are replacing petrol engines at a faster rate, both in the field of vehicular and stationary applications. Attention of the public and researchers have focused mainly on diesel engines. Fuel reformulation as one of these key technologies is being seriously considered for smoke reduction. Exhaust gas Recirculation (EGR) has proved to be effective in reducing NOx. The tests have been conducted on a twin cylinder Dl diesel engine. Engine was modified for testing effect of EGR. Experiments are also conducted with 0%, 9%, 13% 21% and 26% EGR. Effect of EGR on smoke, NOx and other performance parameters such as brake specific fuel consumption, exhaust gas temperature, smoke density and brake thermal efficiency are evaluated. The experimentations were carried out on Exhaust Gas Recirculation on a four-stroke twin cylinder engine. It is proved that the exhaust gas recirculation has definite impact on NOx reduction. However this drop is at the expense of increase in smoke and fuel consumption. The smoke can be controlled using various smoke additives. Brake thermal efficiency decreases marginally with increasing EGR rates. Exhaust gas temperature incases with increase in EGR rates as the exhaust gas that is recirculated has higher temperature than the temperature of inlet air which results in increases in temperature of inlet air.

The quality of measured frequency response functions (FRFs) is adversely affected by many factors, most significant sources being noise and systematic errors. It is also known that the accuracy and the reliability of various analyses using the measured FRFs depend strongly on the quality of measured data. This paper aims to remove one of the major systematic errors in measured FRFs, namely the mass loading effects of transducers. Sherman–Morrison identity has been used for the elimination of mass loading effects of transducers from measured FRFs. The eigenvalues are estimated from corrected FRF’s. The parameters describing the dynamic behavior of supports, bearings and joints are usually not well known. The dynamic model of the system may be affected much more by the usual simplifications of bearings and joints than by slight errors in geometry, mass and stiffness distribution in its main components. This leads to the correction of mathematical model of real systems via identification of local parameters which in this paper limited to joint stiffness parameter. The joint parameters are estimated from corrected eigenvalues; a well known method suggested by U.Pabst and P.Hagedorn has been used for parameter estimation.

This research paper represents the application of Response Surface Methodology (RSM) and Box-Behnken design (BBD) for modeling and an analysis of the influences of dominant Laser transformation hardening parameters: laser power (LP), scanning speed (SS) and focused position (FP) on hardened bead geometries such as hardened bead width (HBW) and hardened depth (HD) of laser hardened surface quality of unalloyed titanium sheet of 1.6 mm thickness, nearer to ASTM Grade 3 of chemical composition using CW 2kW Nd:YAG laser. The effects of laser power, scanning speed and focal point position on the hardened-bead geometry (i.e. hardened bead width (HBW) and hardened depth (HD) were investigated using response surface methodology (RSM). Linear and quadratic polynomial equations for predicting the hardened bead geometry were developed. The results indicate that the developed mathematical models predict the responses adequately within the limits of hardening parameters being used. It is proposed that regression equations can be used to find optimum hardening conditions for desired.

Surface roughness and tolerances are among the most critical quality measures in many mechanical products. Critical quality measure and surface roughness (Ra) in machined parts depends upon metal cutting parameters during the turning process. Researchers have predicted and developed various models for the optimum turning parameters for the desired surface roughness. Surface of a mechanical product can be created with a number of manufacturing processes. As competition grows closer, customers now have increasingly high demands on quality, making surface roughness become one of the most competitive dimensions in today’s metal cutting industry. This paper utilizes regression modeling in turning of Aluminum using response surface methodology (RSM) coupling with of factorial design. A linear and quadratic model will develop for the prediction and analysis of the relationship between the cutting conditions (variables) and surface roughness as well as to study the effect of cutting variables on surface roughness. In the development of predictive models, cutting parameters of cutting speed, feed rate and depth of cut will considered as model variables and surface roughness will considered as a response variables.

In the present paper a case study of “Fatigue Analysis in Connecting Rod Using ANSYS” is carried out. In this paper, finite element analysis of single cylinder four stroke petrol engine using ANSYS. The work has to find out the stresses at various points on the connecting rod and the portion, which is more susceptible to failure and optimization of connecting rod. To evaluate the magnitude and location stresses in the existing connecting rod. This is of great interest to the auto manufactures that which is the portion of the connecting rod which mainly fails so that they can use various methods of hardening the specific area by using special hardening treatments. In response to an increasing demand for fuel-economy, more weight reduction techniques have been proposed to create an optimum connecting rod design. The research aims to maximize weight savings in a connecting rod, without sacrificing the structural performances such as bending strength, buckling strength, and torsional stiffness. The focus of fatigue in ANSYS is to provide useful information to the design engineer when fatigue failure may be a concern. Fatigue results can have a convergence attached. A stress-life approach has been adopted for conducting a fatigue analysis. Several options such as accounting for mean stress and loading conditions are available.

Speed is of chief interest in this era so IIR filters are being designed using HDL languages. The basic second order tunable notch filter is implementable using the Field Programmable Gate Array (FPGA) at 2.4 GHz. Proper pipelining with the power of decomposition-2 over the basic structure of the second order tunable notch filter has to be applied to achieve high speed. The pipelined notch filter can be implementable on virtex-5 FPGA. Parallel computing fast adders and multipliers can be used for less delay and the less power consumption. Baugh Wooly multiplier and carry select adder are to be used to achieve less delay and high speed.

A wireless sensor network (WSN) have many independent sensors to discover physical or environmental conditions such as sound, temperature, pressure, etc. to send the data through the network to a main location. Additional Traffic is created with management requests and responses and the data issuing from the network’s actual sensing application. The system’s energy can reduce by sending and processing the data together, rather than individually. Energy consumption, balancing the network and extending the network’s lifetime are the primary objectives of the routing protocol design in wireless sensor network. In this paper we have discussed the problems of transmitting data over wireless sensor network, proposed the technique for increasing the efficiency of a node along with providing security to the data.

In recent years there has been an enormous growth in wireless communication devices and wireless users. The availability of the spectrum is most important for fulfillment of the demand. Spectrum is a valuable resource in communication. So to fulfill the demand we either need more spectrums or make efficient use of current available spectrum. But as spectrum resources are limited we need to use them efficiently. It is impossible to use spectrum efficiently with the static spectrum allocation policy. Due to this static policy most of the spectrum remains underutilized. To use spectrum efficiently we need to use dynamic spectrum allocation policy. For future wireless communication cognitive radio is the key in expertise. Spectrum sensing is one of the most important functions in cognitive radio (CR) applications. Cognitive radio technology is used as the problem solution key in wireless networks resulting from the limited available spectrum and the inefficiency in the spectrum usage by exploiting the existing wireless spectrum opportunistically. Sensing of spectrum availability has been identified as a key requirement for dynamic spectrum allocation in cognitive radio networks. it involves the detection of primary user (PU) transmissions on a pre assigned frequency band. Primary user licensed band can be sensed via suitable spectrum sensing methodologies. This paper presents three basic spectrum sensing techniques of transmitter detection: energy detection, matched filter detection, and cyclostationary feature detection. A proportional scrutiny of all the techniques has been carried out in terms of probability of detection alarm Pd, probability of false alarm Pf and probability of missed detection pm using simulations. As a final point, result shows that at low signal to noise ratio (SNR), cyclostationary feature detection outperforms better than the rest techniques. For simulation matlab software is used.So in this paper authors are presenting the comparative performance analysis of these three techniques.

The sectorized antennas or switched beam smart antennas have less interference rejection capability due to scalloping. To circumvent this problem adaptive array smart antennas are very suitable. These adaptive array smart antennas involve the array processing to manipulate the signal induced on various antenna elements in such way that the main lobe of an antenna directs towards the desired signal and nulls in the direction of interference. In these smart antennas to locate desired signal, MUSIC algorithm is used as it is highly accurate, stable and provides high angular resolution. Further typical beam forming algorithm used is RLS algorithm as it is faster in its convergence. With use of MUSIC and RLS algorithms eight element adaptive array smart antennas add new possibility of accurate user separation which can improve the capacity of wireless communication system such as 3G cellular system.

Toyota’s Production System (TPS)  is the origin of the Lean manufacturing concept that was introduced in the early 1990s . The concept is widely accepted among scholars and supposed to contribute to sustained competitiveness. Strong focus is set on value creation and waste reduction in the manufacturing processes. “Lean Production is a system of work organization that strives to deliver high quality, low-cost products through the efficient use of resources and the elimination of waste.”  Lean manufacturing relies on certain principles such as standardized processes, Levelled production, JIT practices, visual inspection, and Continuous improvement. Above four research propositions on how the Lean philosophy can contribute to more long-term and sustainable competitive impact. None of these propositions, however, include environmental issues. More recently, the Green manufacturing concept has entered the agenda as a response to negative environmental impacts caused by manufacturing activities. This concept focuses mainly on reducing effects on the natural environment and a number of principles have been outlined: reduction of energy use, reduction of material waste and emissions, use of recyclable materials, fewer manufacturing steps, new manufacturing technology, environmental training, etc. However, the Lean and Green manufacturing concepts have evolved rather independently and there is a need to “unpack the nature of the relationship between lean and green.” .  The research examines the concept that Lean and Green manufacturing secures both economic and environmental sustainability for the long-term growth and prosperity of the Plastic Industries in India by improving productivity whilst minimising the environmental impact of its activities.

This paper presents an eigenvalue analysis for detecting the potential of subsynchronous resonance (SSR) in single-cage induction generator based wind farm. Fixed speed single-cage induction generator based wind farms are considered for study of SSR. The wind farm is connected to the modified IEEE first bench mark system. Detailed model of the study systems are developed and eigenvalue analysis is carried out. It is found that the single-cage induction generator based wind farms are susceptible to SSR when they are connected to IEEE first bench mark system. In this case SSR is occurs at realistic levels of series compensation employed for single-cage induction generator based wind farm. The eigenvalue analysis results are validated using PSCAD/EMTDC software. Hence, eigenvalue analysis can be successfully utilized for investigation of SSR in wind farm connected to series compensated transmission line.

In India the environment of many of the city is very warm. Owing to the increasing population needs, the construction activity is at its boom, resulting in an increase in concrete structures and consequently decrease in green areas. The climate of the city is quiet warm during the months of summer with temperature reaching up to 480C so proper care should be taken to avoid getting any kind of heat related alignment. Also the phenomenon of global warming or climate change has led to many environmental issues including higher atmospheric temperatures, intensive precipitation, and increased greenhouse gaseous emission resulting in increased indoor discomfort condition. Researchers worldwide collectively agreed that one way of reducing the impact of global warming is by implementing “Green Roof Technology” which integrates vegetation, growing medium and water proofing membrane on top of the roof surface. It gives the effect of green plantation on inclined roof to the indoor temperature on any building in hot climate. The experiment showed a promising result where by the average indoor temperature dropped between 0.6°C to 2.7°C as recorded during the observation for bare roof, while average indoor surface temperatures dropped between 4.8°C to 6.9° C with green roof during daytime.

Self-compacting concrete (SCC), also referred to as self-consolidating concrete, is able to flow and consolidate under its own weight and is deaerated almost completely while flowing in the formwork. It is cohesive enough to fill the spaces of almost any size and shape without segregation or bleeding. This makes SCC particularly useful wherever placing is difficult, such as in heavily-reinforced concrete members or in complicated work forms. The objective of this proposed project is to study the different test adopted on self compacting concrete like slump flow test, U-tube, L box, J ring and compare the same with conventional concrete. And also to compare the Compressive Strength values of self-compacting and normal concrete specimens for 3 days, 7 days, and 28 days. And to study the effect of super plasticizer, VMA and fly ash on concrete. All SCC mixtures exhibited greater values in compressive strength after being tested, compared to normal concrete. The compressive strength of SCC is found to be higher than that of normal concrete. This was possible due to the use of mineral and chemical admixtures, which usually improve the bonding between aggregate and cement paste, thus increasing the strength of concrete.

Carpooling (also car-sharing, ride-sharing, lift-sharing), is the sharing of car journeys so that more than one person travels in a car. It helps to resolve a variety of problems that continue to plague urban areas, ranging from energy demands and traffic congestion to environmental pollution. Most of the existing method used stochastic disturbances arising from variations in vehicle travel times for carpooling. However it doesn’t deal with the unmet demand with uncertain demand of the vehicle for car pooling. To deal with this the proposed system uses Chance constrained formulation/Programming(CCP) approach of the problem with stochastic demand and travel time parameters, under mild assumptions on the distribution of stochastic parameters; and relates it with a robust optimization approach. Since real problem sizes can be large, it could be difficult to find optimal solutions within a reasonable period of time. Therefore solution algorithm using tabu heuristic solution approach is developed to solve the model. Therefore, we constructed a stochastic carpooling model that considers the in- fluence of stochastic travel times. The model is formulated as an integer multiple commodity network flow problem. Since real problem sizes can be large, it could be difficult to find optimal solutions within a reasonable period of time. Index Terms—Carpooling, multiple commodity network flow problem, stochastic travel time, time–space network.

The rapid advance of wireless and portable computing technology has brought a lot of research interests and momentum to the area of mobile computing. One of the research focuses is on mobile search engines to leverage context awareness. With wireless connections, users can access information at any place at any time. However, the constraints such as limited client capability, limited bandwidth, weak connectivity, and client mobility impose many challenging technical issues. To keep up with this expansion, search engines the primary gateway to the Internet for more than half of all users must adapt to mobile environments. In particular, search engines must take into account handsets, which are pervasive and person-centric, continuously capturing user-related information. Such data can provide more meaningful search results by augmenting searches with real-world information related to users’ profiles and behavioral patterns. Information about users such as location, how they interact with the mobile device, or what’s occurring in the surrounding physical world is called contextual data. Such information is increasingly accessible via sensors embedded in smart phones leading to many new commercial usage scenarios, such as location-based services and academic research on the topic. Our proposed model captures heterogeneous context data from many mobile sensors. We developed an application architecture that supports context-aware mobile searches, and use real context data from the Reality Mining project.

Cloud computing is the internet based technology widely used in IT industry. Cloud provides everything as a service over internet such as IaaS, PaaS, and SaaS. There are various security and privacy issues on outsourced data. Along with Data confidentiality fine grained access control is strongly desired. There are various access control schemes employing Attribute based encryption have been proposed; many of them suffer from inflexibility in implementing complex access control policies. Attribute based encryption schemes provide the fine grained access to cloud data but computational cost of encryption is increases with complex access policies. In order to alleviate the problems in existing system we proposes the scheme that will use the Hadoop framework which uses the mapreduce technique in order to process all user requests in parallel. In Hadoop HDFS process and stored large amount of data efficiently on distributed environment. we also efficiently revoked the user who will not be able to access to data which he already had access to. Hadoop is a software framework comes with a distributed file system called HDFS (Hadoop Distributed File System) which automatically handles many problems such as task scheduling, fault tolerance and inter-machine communication. Use of HDFS helps in storing the large amount of data on cloud in short time. Data stored in HDFS can be processed using Map Reduce programming model which comes with Hadoop.

During the past few decades Common River sand has become expensive due to excessive cost of transport from natural sources. Large scale depletion of these sources have led to many environmental impacts. In order to overcome these impacts an alternative has to be found in order to replace sand. The manufactured sand (M-sand) has found to be economical alternative to the river sand. M-sand is obtained as a crushing of granite stones in required grading to be used for construction purposes as a replacement for river sand. M-sand has been used in large scale in highways as surface finishing materials and also used in the manufacture of hollow blocks and in light weight concrete prefabricated elements. In this, investigations were carried out to study the compressive strength and split tensile strength of concrete using M-sand as fine aggregate instead of river sand. And compare the results obtained from both the river sand and the M-sand. In order to achieve the strength, cement is replaced by silica fume by 15% in weight and also 1.2% weight of binder super plasticizer is added to obtain workability. The present investigations mainly focused on the M-sand properties and the strength obtained from both the river sand and m-sand. In order to solve the problem of the granite powder disposal from the industries and also to solve the raw materials shortage problem for concrete, studies are being made to utilize the M-sand in the manufacture of varieties of building and ceramics products. This investigation is also based on the comparison of the compressive strength and split tensile strength achieved by the cubes and cylinders in normal sand and M-sand.

This paper presents a p-q control theory to determine reference compensation currents of the three-phase shunt active power filter (SAPF) under Variety of loads. The proposed approach is based on p-q theory to mitigate harmonics less than 5%. Active power filter which has been used here monitors the load current constantly and continuously adapt to the changes in load harmonics. Results obtained by simulations with MATLAB and Simulink show that the proposed approach is more effective on compensating reactive power and harmonic of the load. Index Terms: SAPF, PLL, Programmable voltage source, reactive power compensation, Linear and nonlinear loads, PID Controllers, Simulation.

This work presents a method capable of designing DSTATCOM to reduce harmonic distortion and correct the power factor to improve power quality. The use of alternating current circuits in electrical power system has been a common practice nearly since the very inception of the interconnected power network. The most familiar loads on such a system were the constant power, constant impedance and constant current loads or a linear combination of thereof. In these cases, the voltage and current wave shapes are nearly pure sinusoidal. But this is no longer the case with modern electric power system. Massive use of the nonlinear and time varying devices has led to distortion of voltage and current waveforms. As a consequence, recently the issue of power quality has become important. Both electric utility and end users of electric power are becoming increasingly concerned about the quality of electric power. The term “power quality” has been used to describe the variation of the voltage, current and frequency on the power system beyond a limit. The performance of the system is simulated for Linear and Motor load. Key words: Programmable Source, DSATACOM, Capacitive filter, Power Quality, PI & Hysteresis controller, Motor load.

In modern industry, trend towards using dry and high speed machining has caused much greater heat dissipation in the chip formation zone and for this reason thermal phenomena play a key role in tool life and machinability of the materials. For the improvement of cutting performance, the knowledge of temperature at the tool-work interface with good accuracy is essential. In the present work, the most simplest and economical technique i.e. tool-work thermocouple set-up is developed for the measurement of the cutting temperature in machining. The performance of the setup is evaluated for the materials like EN-8, Al-380, SS-316 and SAE-8620. Machining tests are carried out for these materials for various cutting parameters using carbide tool. Response surface model has been developed for cutting temperature for these materials. Further, the influence of cutting parameters and the thermo-physical properties of work piece materials on response parameters has been studied.
Software-Based Self-Test (SBST) approaches are the effective solution to detect permanent faults at the end of both the production process and during the operational phase, when Very Long Instruction Word (VLIW) processors are used these techniques require some optimization steps in order to properly exploit the parallelism intrinsic in these architectures. In this paper we present a new method from previously known algorithms and automatically generates an effective test program which can produce high fault coverage on the VLIW processor under test, by reducing the test code size which on effect reduces the test duration. The method consists of four stages of parametric phases and can deal with different VLIW processor models. The main aim of our proposed method is to automatically obtain a test program able to achieve high fault coverage with minimum test time and the required resources. Experimental data gathered shows effectiveness of the proposed approach that this method is able to exploit the intrinsic parallelism of the VLIW processor, reducing the grow thin size, and duration of the test program when the processor size grows.

The discrete cosine transform (DCT) and the compressive sampling (CS) are two signal processing techniques with many applications on a great number of engineering fields. In this paper, we advise to apply both techniques to the compression of audio signals. Using spectral analysis and the properties of the DCT, we can treat audio signals as thin signals in the frequency domain. This is particularly true for sounds representing tones. On the other hand, CS has been traditionally used to acquire and compress certain sparse images. We propose the use of DCT and CS to obtain an efficient representation of audio signals, especially when they are sparse in the frequency. By using the DCT as signal preprocessor in order to obtain a sparse representation in the frequency domain, we show that the successive application of CS represent our signals with less information than the well-known sampling theorem. This means that our results may possibly be the basis for a new compression method for audio and speech signals. Key words—Audio signals, Compressive sampling, DCT, PSNR, SNR,Sparsity.

The biggest threat to the Internet is the fact that it was never really designed. For e.g., the BGP protocol is used by Internet routers to exchange information about changes to the Internet's network topologies. However, it also is among the most fundamentally broken; as Internet routing information can be poisoned with bogus routing information. Instead, it evolved in fits and start, thanks to various protocols that have been cobbled together to fulfill the needs of the moment. Few of protocols from them were designed with security in mind. or if they were sported no more than was needed to keep out a nosy neighbor, not a malicious attacker. The result is a welter of aging protocols susceptible to exploit on an Internet scale. Here are six Internet protocols that could stand to be replaced sooner rather than later or are (mercifully) on the way out.
Since decade, with rapid growth of available multimedia documents and increasing demand for information indexing and retrieval, much effort has been done on text extraction in images and videos. There are many challenges and difficulties for designer and developer of video extraction process. A lot of work has been done in the field of video extraction from multimedia data. But most of the work is application specific and there is still need of work in designing domain independent systems. This is because there are so many challenges when extracting video with variation in fonts, size, color, alignment, orientation, illumination and background. Problem of video extraction get very difficult because of these deviations. This paper presents a conceptual framework for video extraction derived from the research literature and used as a means for surveying the research literature.

MANETs require a unique discrete and persistent identity per node in order for their security protocols to be viable, Sybil attacks pose a serious threat to such networks. A Sybil attacker can either create more than one identity on a single physical device in order to launch a synchronized attack on the network or can switch identities in order to weaken the detection process, thereby promoting lack of responsibility in the network. In this research, we propose a lightweight scheme to detect the new identities of Sybil attackers without using centralized trusted third party or any additional hardware, such as directional antennae or a geographical positioning system. Through the help of wide simulations and real-world test bed experiments, we are able to demonstrate that our proposed scheme detects Sybil identities with good precision even in the presence of mobility.

Data Mining is the process of extracting the information from a dataset and transforms it into an understandable structure. An essential problem in microarray data analysis is to discover phenotype structures. The existing techniques for phenotype structure discovery are singleton discriminability based approach and combination discriminability based approach.The goal is to discovery groups of samples equivalent to different phenotypes (such as disease or normal). Novel sequence dissimilarity is to be proposed for systematic expression values among genes. This is important for the subsequent analysis by the biologists. The sequence model is that only a small number of genes are needed to achieve high phenotype discriminability.A g* sequence model to characterize the phenotype structure.This property helps to improve the robustness of the proposed model and enables to identify the highly discriminative signatures with only a small number of genes.

Energy-efficient mechanism for wireless communication on each sensor node is so crucial. Specially, the jobs sending and processing sensing data information from on sensor node to the others are more majority parts than merely sensing some events. Energy-constrained sensor networks periodically place nodes to sleep in order to extend the network’s lifetime. Denying sleep effectively attacks and traditional routing protocol mechanisms each sensor node's critical energy resources and rapidly drains the network’s lifetime. Thus, energy-efficient routing protocol in wireless sensor networks is necessary for increasing the network lifetime and is also influenced by many challenging factors in terms of energy, processing, and storage capacities. In this paper, we designed and implemented a Synthesized Adaptive Routing (SAR) protocol for wireless sensor networks and evaluated the performance of SAR by comparing with existing routing protocols. Finally, the performance evaluation results show that SAR provides the facilities to reduce energy consumption along with increasing networks lifetime.

In last few years, the complexity at computer networks is increasing exponentially. These complex network architectures have resulted in increased demands of information security measures. Compared to the traditional central and static networking control mechanisms, the biologically inspired network security mechanisms are becoming a promising approach for fulfilling current (and future) network requirements. Hence the proposed system is inspired from the biological process or metaphor Homeostasis. Homeostasis is a biological system able to maintain a stable status by taking actions upon the observed continuous changes in their internal and external environments. Using this concept the network will be able to detect the malicious anomalies (change in external environment) and to generate the response (such as traffic rate limiting, node quarantine) to maintain the stable status of system. Anomaly based detection technology has the high rate of false alarms but the ability of anomaly-based technology to integrate with other security products will create a security elements that can effectively work together. This detection does not end the task but it’s a start of taking steps towards the mitigation of impact of malicious anomaly and to generate the signature for future use. When solution for any anomaly is unavailable it takes time to make it available. This time period can be utilized by the anomaly to affect the system. Thus mitigation steps will enhance ability of system to maintain the stability of system. In this way the proposed system may play an important role in network security technology.

Identity crime is well known, prevalent, and costly; and credit application fraud is a specific case of identity crime, involving synthetic identity fraud and real identity theft. Identity crime has become prominent because there is so much real identity data available on the Web, and confidential data accessible through unsecured mailboxes. It has also become easy for perpetrators to hide their true identities. Credit card fraud is an element of identity fraud. It can have far reaching effects, since the information on the card can be used to perpetrate other types of identity theft crimes. The existing non-data mining detection system of business rules and scorecards, and known fraud matching have limitations. To address these limitations and combat identity crime in real time, this system designs a new multilayered detection system complemented with two additional layers: communal detection (CD) and spike detection (SD).CD finds real social relationships to reduce the suspicion score, and is tamper resistant to synthetic social relationships. It is the white list-oriented approach on a fixed set of attributes. SD finds spikes in duplicates to increase the suspicion score, and is probe-resistant for attributes. It is the attribute-oriented approach on a variable-size set of attributes. Together, CD and SD can detect more types of attacks, better account for changing legal behavior, and remove the redundant attributes. Although this research is specific to credit application fraud detection, the concept of resilience, together with adaptivity and quality data discussed in the paper , are general to the design, implementation, and evaluation of all detection systems.

In large amount of sensor network, specifically in case of data aggregation it should reduce the amount of communication and energy consumption. Recent research on wireless sensor networks has proposed a robust aggregation framework called synopsis diffusion which combines multipath routing schemes with duplicate-insensitive algorithms to accurately compute aggregates (e.g., predicate Count, Sum) in spite of message losses resulting from node and transmission failures. But these aggregation frameworks aggregation frameworks does not solve the problems which are appearing at base station side. Overhead of per node communication has been occurred regardless of increase in network size. In this paper, we make the synopsis diffusion approach secure against attacks in which compromised nodes contribute false sub combined values. In this regard, the alternative verification algorithm by which the base station can determine if the computed aggregate (predicate Count or Sum) includes any false contribution. In this paper, we study the compromised-node and denial-of-service is the two key attacks in wireless sensor networks. We argue that multipath routing approaches are highly vulnerable for such kind of attacks. The mechanisms that we developed so far will generate randomized multipath routes. The routes taken by the shares of different packets change over time in this design. So, we analytically investigate the security and energy performance of proposed schemes.

Data mining is a process which finds useful patterns from large size of data. And Data mining commonly involves four classes of tasks or techniques Classification, Clustering, Association Rule Mining, and Regression. Among these all the Clustering is a task of assigning a set of objects into groups called clusters. The clustering algorithms can be having two categories; hard clustering and soft (fuzzy) clustering. In the Hard clustering data’s are divided into different clusters, where each data element belongs to only one cluster. In soft clustering, data elements belong to more than one cluster, and associated with each element by the levelt of membership. Here, in this paper represent a survey on fuzzy c means clustering algorithm.
System-on-chip (soc) based system has so many disadvantages in power-dissipation as well as clock rate while the data transfer from one system to another system in on-chip. At the same time, a higher operated system does not support the lower operated bus network for data transfer. However an alternative scheme is proposed for high speed data transfer. But this scheme is limited to SOCs. Unlike soc, network-on-chip (NOC) has so many advantages for data transfer. It has a special feature to transfer the data in on-chip named as transitional encoder. Its operation is based on input transitions. At the same time it supports systems which are higher operated frequencies. In this project, a low-power encoding scheme is proposed. The proposed system yields lower dynamic power dissipation due to the reduction of switching activity and coupling switching activity when compared to existing system. Even-though many factors which is based on power dissipation, the dynamic power dissipation is only considerable for reasonable advantage. The proposed system is synthesized using quartus II 9.1 software. Besides, the proposed system will be extended up to interlink PE communication with help of routers and PE’s which are performed by various operations. To implement this system in real NOC’s contains the proposed encoders and decoders for data transfer with regular traffic scenarios should be considered.

Accidents cause a lot of damage and loss of life and property. Current statistics show accidents are increasing day by day .Most of the times, there is no one around the victim to help him in and offer immediate need. When an auto crash occurs suddenly, the reaction of the emergency services now becomes a race between life and death. Today, wireless innovation has tilted the odds in favor of success like never before. Before, the people in the emergency services had little more to rely upon than raw courage. Now the world of wireless has inspired an entirely a new way of managing and minimizing the death rate due to auto crash. The scene of a fatal accident is always a theater where man and technology face the ultimate test. Whether the emergency is fire, earthquake or flood, relief or needed medical attention in this case, the stakes are always high. Indeed, wireless communications has become extremely important in emergency response. Obviously the most important tool in any situation is people. But better information with the aid of machine-to-machine (M2M) network means better decision making and that means technology is helping to save property and lives. Today’s standard for reporting on car accidents is an extremely slow process. Presently, the accident needs to be physically reported and announced via a radio broadcast or a portable GPS unit before a driver is alerted. This approach also requires that the driver is listening to the radio or is using the GPS. This project is an intelligent Accident alert system which not only notifies accidental alert but also provides the exact location where the accident has taken place. Many lives could have been saved if the required attention was given at the time of need. With the help of this system, the required attention can be given to the victim as the accelerometers fitted into the systems alerts the nearby police stations and hospitals.

A biometric system depending on one biometric feature is not a reliable system. Identification based on multiple biometric features is best option to overcome the disadvantages of single feature biometric system. The main aim is to incorporate the biometric feature of user into cryptographic key to make biometric system more secure. We go one step further to try to incorporate the multiple biometric features into cryptographic key generation to provide more security. In this paper, we have proposed an approach to design a biometric system with cryptographic key generation. This approach is consisting of three stages 1) Feature extraction 2) Multimodal biometric template generation 3) Cryptographic key generation. In this approach, the features, facial and minutiae points are extracted from face and fingerprint images respectively. The extracted features are fused together at feature level to generate templates. From these templates, cryptographic key is generated.
