Published: July 2019

This article discusses the issue of theoretical background of capacity of new load handling tools of continuous loaders for organic fertilizers on the basis of kinematic analysis of their motion. Loader efficiency is estimated by a set of performances the main of which is loading capacity. The loading capacity is determined by design and kinematic parameters of tools. Theoretical determination of capacity is an important scientific task, its solution would permit to substantiate loader parameters for predetermined operation conditions. Kinematic analysis of spiral, vane, shredding screw load handling tools is performed. Capacity of shredding tools is determined as a function of design and operation parameters as well as physicochemical properties of organic fertilizers. The obtained equations take into account motion pattern of tools, kinematic and design parameters as well as physicochemical properties of manure. The capacity depends quadratically on tool diameter. Dependence on other parameters is in fact directly proportional. The influence of tool angular velocity and its forward velocity is related with trigonometric functions of rotation angles during separation and gripping of organic fertilizers.Â Â

Authors: Y. Golovina Natalya , Y. Krivosheeva Svetlana
Published: July 2019

The method for estimating the fatigue life of power plant pipelines based on the results of one or two tests without destruction is proposed. The proposed method uses the classical model of fatigue resistance. Weller curves for power plant pipelines are determined experimentally, the experimental data are presented. Three curves are constructed for the probability of destruction of 2%, 50%, and 98%. The proposed method uses the hypothesis of linear summation of Palmgren-Miner injuries. When developing the method, much attention is paid to the ways of schematizing the actual process of loading the pipelines. Calculation of the distribution of the total number of cycles was carried out by the â€œRainflowâ€ method and the Gusev method. The application of this method with a set of design measures provides more than fivefold margin for fatigue resistance of all pipelines of the power plant.Â
A Bayesian Approach to Prediction of Flood Risks
Authors: Izzati Mohd Roslin Nur , Mustapha Aida , Azah Samsudin Noor , Razali Nazim
Published: July 2019

Flood is a temporary overflow of a dry area due to overflow of excess water, runoff surface waters or undermining of shoreline. In 2014, Malaysia grieved with the catastrophic flood event in Kuala Krai, Kelantan, which sacrificed human lives, public assets and a total of RM 2 billion loss. Due to uncertainties in flooding event, this research is set to compare three variations of Bayesian approaches in classifying the risk of flood into two classes; flood or no flood. The study involved data from Kuala Krai, which serves as the main observation point. The dataset contains six attributes, which are water level, rainfall daily, rainfall monthly, wind, humidity, and temperature. The classification experiment will be conducted using three variants of Bayesian approaches, which are Bayesian Networks (BN), NaÃ¯ve Bayes (NB), and Tree Augmented Naive Bayes (TAN). The outcomes of this research will show the best algorithm performance in term of accuracy for three Bayesian-based learning prediction algorithms. In the future, this prediction system is hoped to assist related agencies in Malaysia to categorize land areas that face high risk of flood so preventive actions can be planned in place. Â Â Â

Authors: L. Lvov Nikolay , S. Khabarov Stanislav , Yu. Gavrikov Mikhail
Published: July 2019

This article discusses the problems of creating an integrated system for monitoring the technical condition of highly responsible helicopter units, and analyzed options for its creation. Fiber-optical technology is considered as a technology, on the basis of which it is possible to build an integrated system, since this technology makes it possible to measure various physical parameters such as vibration, deformation, temperature, acoustic emission and other parameters, and due to the miniature dimensions of the fiber-optic light guide. It can be built into the PCM design, which is a relevant factor due to the growth use of PCM in the design and manufacture of helicopters. The results of bench and flight tests of helicopter pilot and rotor blades with fasteners using fiber optic deformation sensors based on a Bragg fiber grille demonstrate the fundamental possibility of creating a system for monitoring the technical condition of helicopter rotors using fiber optic sensors .Also, there are examples of creating other elements of an integrated monitoring system based on the use of fiber-optic technology, such as a system for signaling the breakdown of air flow and flutter on the helicopter rotor blades, a system for measuring the weight and alignment of helicopter cargo and a system for monitoring the technical condition of the airframe.Â Â

Published: July 2019

According to studies [1], cutting tools with plates made of cutting ceramics alloyed with carbide-forming elements have higher heat resistance than standard plates made of cutting ceramics in the delivery stage, since their properties do not meet the requirements. Cutting ceramics with the addition of a nickel alloying element to its main standard fraction has a low heat resistance. With the addition of the manganese alloying element, heat resistance and corrosion resistance and wear resistance of cutting tools equipped with cutting ceramics are reduced. The main alloying element is chromium, which, depending on its quantity, indicates increased or high heat resistance in cutting ceramics.Â Â

Authors: Vybornov A. , Koltsov P. , Kulkova M. , Yudin A. , Goslar T.
Published: July 2019

The article deals with the problems of Neolithic chronology in the steppe and forest-steppe regions from the Volga to the Don. The main criterion of the transition to the Neolithic in the region should be considered the appearance of ceramic ware. In the southern region, the onset of the Neolithic was associated with indigenous processes in the period 7700-7200 years ago, with some influence from the Caucasus. In the northern territories, Neolitization occurred in 7500-7200 years ago and was influenced by the cultures of Central Asia. The early Neolithic on the border between the steppe and forest-steppe in the Volga river basin is represented by the Elshanka complexes with earthenware. The chronological ratio of the Neolithic of the southern and northern territories indicates the influence of steppe cultures on the development of the population in the forest-steppe of the Middle Volga region.Â Â Â

Authors: Widodo Arry , Abdul Wahid Nabsiah
Published: July 2019

This study aims to determine the reasons why Indonesian consumers buy innovative green products (Pertalite RON 90) using CAB attitude theory. This theory assumes that individual behavior (such as the decision to buy) is closely related to how they evaluate decisions of the cognitive, affective and conative aspects. This study was designed to be quantitative. The causal relationship between variables will be examined through questionnaires to be distributed to consumers of Indonesian motor vehicles using gasoline. The findings are expected to provide insight into whether ABC's theory of attitude, popular theory in consumer behavior literature is useful and applicable in explaining why consumers, especially Indonesian petrol consumers buy innovative green products (represented by Pertalite RON 90). From these findings, researchers and practitioners will be able to understand the importance of the cognitive, affective and conative components of the theory of consumer behavior and apply it accordingly. This study is important for the progress of CAB behavior theory through tripartite attitude structure model which consists of attitude stimulus through stimulus used to measure each component of cognitive, affective and conative behavior. The proposed model is intended to identify key concepts that shape attitudes that are useful for predicting outcomes to make accurate predictions using component attitude concepts: Cognitive, Influencing, and Conative (CAB), following tripartite behavioral models (Schiffman and Kanuk, 2004, Solomon, 2002; Breckler, 1984; Rosenberg and Hovland, 1960; Boulding, 1956).Â Â Â
Incorporating Social Networks in Business Relationships of Retail SMEs for Better Business Performance
Authors: Asmahani Ibrahim Nor , Mohd Roslin Rosmimah
Published: July 2019

The presence of hypermarkets with modern retail format has impacted the performance of retail small medium-enterprises (SMEs) in Malaysia. The challenges of remaining competitive and the ability to sustain the business have pushed many retail SMEs to cease operations within a short period after commencement. Despite these challenges, retail SMEs can still attain competitive advantage through the strategies of strengthening and maintaining business relationships with their social networks. This study postulates that fostering social networks, specifically on the notion of homophily or similarities among social network members, is able to lure valuable resources needed by retail SMEs in achieving superior business performance. Unfortunately, only few studies have focused on social networks from within the Asian context and many tend to overlook the importance of social networks specifically in retailing. This study also suggests the relationship between value and status similarities of retail SMEs and their ability to coordinate efforts in horizontal relationships. Therefore, this study extends the discussion on the role of social networks towards better business performance of retail SMEs in Malaysia by conceptualizing a framework indicating the importance of value and status homophily on coordination of activities leading to business performance of retail SMEs.

DietSkan: Food Volume Estimation for Dietary Intake Analysis Using 3D Mesh Scanning
Authors: Makhsous Sep , Gentsch Jack , Rollins Joshua , Feingold Zachary , Mamishev Alexander
Published: July 2019

The prevalence of obesity, found in more than 38% of worldwide adults, is causing dietary measurements to become increasingly important. Most methods for tracking dietary intake utilize estimating the amount of food consumed to determine calories and nutritional content. Currently used methods of dietary tracking are either tedious or inaccurate. Our proposed method for dietary tracking is called DietSkan. It combines an off the shelf 3-Dimensional (3D) scanner, the Structure Sensor, with a smartphone application to produce a 3D reconstructed mesh scan of food items. The DietSkan process requires the desired food item to be scanned and exported for volume calculation. Then, using a 3D mesh manipulation tool, a 3D mesh, enclosing the consumed food, is constructed to obtain volume. The volume measurements achieved using the DietSkan algorithm average only 6% error and allow a user to track their dietary intake simply and effectively. The DietSkan system simplifies the estimation process and improves measurement accuracy when compared to current common practices.Â Â

The purpose of this research was to synthesize zeolite-A (Ze-A) and zeolite-Y (Ze-Y) using silica sources from silica gel waste, and also improving adsorption capacity with Fe which was trapped in the synthesized zeolites:Â  Ze-Fe-A and Ze-Fe-Y. All synthesized zeolites were tested with lead solution of 40 mg/L at pH 5. For BET specific surface area, the parent Ze-A and Ze-Y presented surface area of 27.02 and 211.42 m2/g, respectively, whereas Ze-Fe-A and Ze-Fe-Y presented a lower surface area of 10.90 and 28.22 m2/g, respectively. SEM and TEM image demonstrated the cubic and polygon shapes for Ze-A and Ze-Y, respectively, while their modification with Fe presented more round shape. Additionally, both modified zeolites with Fe presented higher adsorption efficiency than their parents. Although the modified zeolites gave lower surface area, the efficiency removal of lead showed higher capacity than zeolite without Fe. It could be concluded that the adsorption mechanism of modified zeolites did not only rely on physical adsorption, but also on chemical adsorption. Â Â Â Â Â

Authors: Sin Mun Lau , Mohd Nadzir Masrina , Roy Chowdhury Shiplu , Fauzi Mh Busra Mohd
Published: July 2019

In this research, injectable collagen-chitosan conjugates (Col-Chit-Ph) hydrogel was formed by oxidative coupling of phenolic hydroxyl (Ph) groups in polymer chain via peroxidase-catalysed crosslinking reaction. The resulting Col-Chit-Ph solutions formed rapid hydrogel at physiological conditions by utilizing H2O2. The amount of chitosan in the compositions of Col-Chit-Ph hydrogels influenced the mechanical properties of the hydrogels. Here, conjugates having Col:Chit ratio of 1:1 showed greater resistance to compression compared to conjugates having Col:Chit ratio of 3:2. Meanwhile, the efficiency of cell attachment for conjugates with Col:Chit ratio of 4:1 is higher than conjugates with Col:Chit ratio of 1:1. Although the biological properties of hydrogel was good at Col:Chit ratio of 4:1, this hydrogel easily destroyed by external force. However, with higher amount of chitosan in the composite, hydrogels were more mechanically stable. This indicates the importance of the chitosan ratio to the novel Col-Chit-Ph injectable hydrogel composite.Â Â Â

Published: July 2019

Multiple sequence alignment is one of the recurrent assignments in Bioinformatics. This method allows organizing a set of molecular sequences in order to expose their similarities and their differences. Although several applicable techniques were observed in this re- search, from traditional method such as dynamic programming to the extent of widely used stochastic optimization method such as Simu- lated Annealing and motif finding for solving this problem, their use is limited by the computing demands which are necessary for ex- ploring such a large and complex search space. This paper presents a new genetic algorithm, namely SOGA (Space Oriented Genetic Algorithm for Multiple Sequence Alignment), which has two new mechanisms: the first generates the population with randomly inserting the space between the selected sequences and the second applying new crossover and mutation operator, within an iterative process, to generate new and better solutions. This method is simple and fast. Its performance will further be tested on standard benchmark databas- es and will be compared with well-known algorithms. However, as its solutions clears that there is scope for further improvement.Â

Published: July 2019

This investigation shows the results on aggressive sulphuric acid on the concrete combined with rice husk ash (RH) when partially replaced for ordinary Portland cement. The husk ash, which mainly contains aluminum ion, silica, iron and calcium oxides, is an industrial waste and poses disposal problems. In this study, the effect of various concentrations (1%, 3%, 5%) of sulphuric acid (H2SO4) on Concrete replaced with various percentages (0%,5%,10%,15% and 20% by weight of cement) of RH is evaluated in-terms of residual compressive strength. The loss of compressive strengths of concrete immersed in various H2SO4 solutions for 7 days 28 days and 60 days indicates that at upto 10% replacement increase in strength was observed after which strengths were decreasing. This increase in strength is attributed to pozzolanic activity of RH.Â Â

Estimation of properties of mixed waste cooking oil for production of biodiesel
Authors: S. V. S. R. Krishna B. , B.K Shivaraj
Published: July 2019

The major drawback of production of biodiesel in large scale is the cost of raw materials. Raw material source of biodiesel is mostly plant oil (Jatropha, Pongamia, Mahua, Neem, Cotton seed oil etc.) which requires large land area to grow. One of the best methods to reduce the production cost of biodiesel is to employ low quality feedstock, for instance waste cooking oil (WCO). This also solves the disposal problem of WCO. This is socioeconomic and environment friendly, it does not compete with edible oil resources. This study represents the biodiesel production from mixed waste cooking oil. Waste cooking oil collected from different hotels around Manipal, Udupi district of Karnataka State, and India. Collected WCO from various sources (from palm oil and sunflower oil users) have different physical and chemical properties. These WCO has mixed in different ratios ie. 50:50, 75:25 and 25:75 to reduce free fatty acid content of WCO without any chemical pre-treatment. Physio-chemical properties of mixed WCO has been carried out.

Authors: Sangita Rautray Sushree , Ranjan Das Manas
Published: July 2019

Self-Compacting Concrete (SCC) is becoming a popular choice in concrete industries due to its filling ability in congested reinforcement and its auto compacting nature. In the present work, an attempt has been made to investigate the properties of fresh and hardened concrete made by partial replacement of cement by fly ash and ground granulated blast furnace slag (ggbs) in different percentages. The essential properties of freshly prepared concrete like flowability, passing ability, filling ability are determined by slump flow test, slump flow T50cm, V-funnel, J-ring and L-box test. The values are found to satisfy EFNARC guidelines. Tests have also been conducted to assess and analyze the properties of hardened concrete such as compressive strength, split tensile strength and flexural strength. Thus an attempt has been made to develop a formulation of an economically feasible and environment friendly self-compacting concrete.
Power quality management using statcom for grid interfaced wind turbine controlled by microcontroller
Authors: Singh Panwar Mohan , Ajay Kumar Bansal Dr.
Published: July 2019

Input source for wind power generation in wind turbine is wind. Variation of wind is uncontrolled. Quality of power gener- ated in a windmill is very poor due to uncontrolled and fluctuated nature wind. As per International Electro-technical Commission standard, IEC-61400 norms the power quality and measurements of wind turbine is to be calculate. Electrical energy generated from wind power is based on minimum pollution of environment as comparative to conventional sources of generation. In a grid connected wind power system there are some power quality issues. In grid integrated wind power systems, quality of power is measured by active power, reactive power & variation of voltages measured under guidelines of national & international standards. In this proposed system, the energy generated by wind turbine is converted to DC & DC bus is charged. A microcontroller regulated PWM inverter convert this DC voltage to AC to feed it to grid. The pro- posed DC Bus is augmented by PV (photovoltaic) charged Battery Based PWM controlled STATCOM.

Authors: R. Patel Jay , K. Rathod Manish
Published: July 2019

Latent heat energy storage using macro encapsulated phase change material is an emerging technique for thermal energy storage applica- tions. The main aim of the present investigation is to investigate the melting process of phase change material filled in different shaped configurations. The selected different cavities are square, circular and triangular. A mathematical model based on convection dominated melting is required to be developed, especially in view of the complex flow geometries encountered in such problems. Thus, an attempt has been made to develop a model using ANSYS Fluent 16.2 to investigate the heat transfer rate and solid-liquid interface visualization of PCM filled in different shapes of cavity. It is found that triangular shaped macro encapsulated PCM melts faster than square and circu- lar shaped encapsulated PCM.

The main objective of our research work is to acquire good quality of an image which is blurred. Therefore, in this research our effort is to propose an advanced algorithm to improve the quality of an image by eliminate the blur in an efficient manner. In this paper, two types of blurred images (i.e., Gaussian blur and out of focus) are used. Deblurring techniques are mostly used to eradicate the blur of an image using different methods & parameters. To reimburse blur different types of methods like algorithm, filtering techniques, fuzzy based approach, support vector machine are used. Blur detection methods are used to eradicate the blur from a blurred section of an image which is caused by the out of focus blur and Gaussian blur.

In Today’s world data is collected at an unpredictable scale from various application areas. Prior to the arrival of Big Data, all the data that was generated was handled manually. With data being produced in the range of terabytes today, that is impossible. To make the situation worse, almost 80% of the data generated by organizations is unstructured. This means that it cannot be understood in its avail- able format. It is very difficult and risky to make decisions just based on such crude data. In order to make quick, yet correct decisions, the generated data has to be optimized. This Paper discusses to create an end-to-end system to optimize approximately 6 million records of unstructured data provided as .txt files, which is in the form of strings and numbers into understandable or structured data. The next step is to analyse the structured data in order to make calculations on the given dataset. Finally, the analysed data will be represented in the form of dashboards, which are tabular reports or charts. In this Paper, unstructured data in the form of .txt files will be transformed into structured data in the form of tables through the SQL stored procedures in SQL Server Management Studio (SSMS). Along with the data, four other tables called dimensions will be created and then all five tables will then be integrated using SQL Server Integrated Ser- vices. Then an Online Analytical Processing (OLAP) cube is built over this data with product, customer, currency and time as its dimen- sions using the SQL Server Analysis Services (SSAS). At last this analysed data is then reported through dashboards through SQL Server Reporting Services (SSRS).The results of the analysed data is viewed in the form of reports and charts. These reports are customizable and a variety of operations can be performed on them as required by an organization. Since these reports are short and informative, they will be easy to understand and will provide for easier and correct decision making.

Published: July 2019

The paper considers the problem of conceptual modeling of the domains, in which a large number of changes takes place, possesses a number of specific features. Some of the features are connected to the nature of the ongoing changes. The problem becomes severe when the domain contains a large quantity of independently acting agents that can produce changes in various parts of the model, the sets of interrelated data being changed by different agents independently.Besides that, when supporting the dynamic nature models the possibilities of future changes in model objects might largely be deter- mined not only by their current state, but also by the past state - history of the objects in the model. The support to such history inside the current state of the object can be difficult, cumbersome or impractical for other reasons, which also stimulates the search for new ap- proaches to ensure the map of the changes of objects in the domain model.It is offered to receive the decision by single out the individual information identities, that can be called state trajectories from the con- ceptual point of view and object traces from the implementation point of view. They represent a sequence of changes in the state of mod- el objects essential for its support. The traces can fix not all changes of the corresponding objects, but only those which have an influence on the further behavior of the model. Various ways of supporting of traces are considered. The paper presents an approach to the deter- mination and the support to the traces, based on using a combination of methods of the intensional logic and applicative computational systems.
Steel plate shear wall – a 20th century review
Authors: R. Vhatkar Sudarshan , D. Jadhao Pradip
Published: July 2019

This paper provides a brief summary carried out in past analytical and experimental research work on steel plate shear walls with empha- sis given up to 20th Century. In buildings, two different systems exist to resists the loads viz., gravity load system and a lateral load sys- tem. To transfer the vertical loads to the footing gravity load system is used while lateral loads due to wind and seismic loads are resisted by the Lateral Load Resisting System (LLRS). Steel Plate Shear Walls (SPSW) is relatively a new type of LLRS; it has many distinct performance benefits including large displacement ductility capacities, high elastic stiffness properties, and stable hysteresis behavior as compared to other LLRS. The experimental results were also compared with simplified analytical models. The capacity of SPSW is li- mited to elastic buckling strength of its plate panels. This practice results not only in an undesirable one, but also in a conservative design, where columns buckle and may yield before the plate reaches a fraction of its capacity. With failure plate buckling is not synonymous and along its boundaries if plate is supported adequately, as in the case of SPSW the post buckling strength may be several times theoret- ical buckling strength.
Survey on bagasse cogeneration in sugar plants of north Karnataka

Published: July 2019

Cogeneration is the idea of converting two forms of energy from one fuel. In the sugar industry from bagasse two forms con- verted are heat and electrical power. The sugar industries utilise bagasse to generate power and to operate the plant . Here the bagasse serves as a fuel to the Boiler and this power consumption is known as captive power generation. The so generated power will be more than the power required for the running of the industry. The remaining excess power can be fed to the power grid as a power export.The actual site survey of different bagasse cogeneration plants has been carried out and included in this review. Also, this paper reviews the performance of the bagasse cogeneration plants all over the world. The review includes not only study on the power genera- tion plants but also throws an insight to identify the scope for the study on the performances of the cogeneration plants in Karnataka based on the global perview. The effective and efficient utilisation of the bagasse cogeneration plants could be identified for the im- provement of the performance of the cogeneration plants and also the economics of running a sugar industry.
