Authors: Sharma P , Kumar V 
Published: August 2019

Abstract
The vehicle dynamics gives lot of consideration to quality of ride and the value of comfort. These two are dependent on the suspension system of the vehicle. Researchers are doing a lot of work in the field of improving these two parameters. A lot of approaches and control systems like ANN, GA based system, fuzzy and hybrid control systems have been formulated, simulated and tested. This paper deals with mathematical modeling and simulation of passive and semi active system. The semi active system modeled here contains a new approach of using intelligent controller based on Brain functioning with emotional signal, known as BELBIC. The use of this controller has not been tested for suspension system as identified through rigorous literature survey. The both systems are simulated for their response to disturbance of road as step function and as profile of cosine shape. The results of passive and proposed semi active system were analyzed to compare their performance in terms of displacement of sprung mass and suspension travel as well as their settling time. The BEL controlled system has performed very good. The displacement of sprung body has been reduced in both the cases of road disturbances. The response against step input is better than cosine. Similarly settling time has also shown in improvement for step and cosine function.

Authors: Ray M P , Puranik B P , Bhandarkar U V 
Published: August 2019

Abstract
High resolution multi-fluid solvers are developed, using a fifth order weighted essentially non-oscillatory approach for spatial reconstruction and a third order Runge-Kutta scheme for temporal integration. Several flux evaluation schemes, comprising of exact and approximate Riemann solvers available in the literature are incorporated. Multi-fluid simulation capability is achieved using the ghost fluid method. Two-dimensional geometry is considered, and the Euler equations of gas dynamics are used as the basic flow model in view of the fact that the viscosity effects are negligible for most of the time of interest. Relative performance of these solvers is evaluated for several one- and two-dimensional test cases, before simulating the shock-bubble interaction. Three Mach numbers and air-Helium gas combination is studied and the results are presented in this study. Numerical schlieren images are rendered for qualitative study while time evolution of several integral features such as the axial and lateral deformations, the translational velocity of the bubble, the circulation in the flow-field, and the stretching rates of the bubbles are analyzed for quantitative studies. The results are consistent with the strength of baroclinic source term.

Abstract
The competition in market is increasing day by day and there is always fluctuation in demand and supply. To retain in market, organizations have to meet the customer demand to get customer utmost satisfaction. Mainly, micro, small and medium enterprises (MSMEs) are struggling with such problems as they are having limited resources. To stay remain in competition there is only one way to improve productivity by optimum utilization of available resources by reducing waste and defects in product and processes. In this context, Lean Six Sigma (LSS) is emerging as a potential strategy that can be able to improve the processes very easily. LSS is the integration of two different continuous improvement approaches; Lean and Six Sigma that is used to reduce waste and variation in processes but many organizations still facing challenges to implement LSS successfully. So, the main aim of present study is to identify the barriers of LSS and prioritize them using analytic hierarchy process (AHP). The most critical barrier category comes out as management based barrier as it possess highest AHP index. This study will help the mangers and researchers to focus on critical barriers of LSS so as to implement it in a smoother way.
Effect of milling time on the compressive high strain rate behavior of Al-SiC Composite
Authors: Chouhan Tulsi , Soni Manoj , Chouhan Hemant 
Published: August 2019

Abstract
Aluminum-Silicon carbide (Al-SiC) metal matrix composite (MMC) have gained importance as a new class of material capable of serving the future generation brake material requirements. The presented study deals with the compressive high strain rate behavior of Al-SiC composite comprising 15% SiC by weight. The MMC specimens were fabricated by powder metallurgy route. Three different ball milling times were selected for the study purpose after optimizing all other processing parameters. Incorporation of SiC invariably enhanced the hardness, quasi-static and dynamic compressive strength of Al-SiC composite. Hardness was noted to enhance as a function of increasing ball milling time. However, the quasi-static and dynamic compression properties were recorded highest for the ball milling time of 240 minutes. The study confirms that minor addition of a suitable reinforcing material can significantly improve the properties of an MMC. Also, increasing the ball mill time may not necessarily enhance all the material properties.

Authors: Krishna Anand V G , Parammasivam K M 
Published: August 2019

Abstract
Trench film cooling employs film holes embedded in slot depression created on the surface with the application of thermal barrier coating. The aim of present investigation is to analyse the film cooling effectiveness (FCE) of single film hole diameter (1D) wide trench, 1D trench with trailing edge modifications and to compare its performance with two film hole diameter wide trench (2D). Results of the study show that single film hole diameter wide trench with bevelled trailing edge modifications produced improved film cooling performance compared to two film hole diameter wide trench and other tested cases. Experimental results show close agreement with computational data. The single film hole diameter wide trench with bevelled trailing edge shows highest local, lateral averaged and spatial averaged FCE. The bevelled model trench delivered higher FCE at all three tested blowing ratios.

Published: August 2019

Abstract
Nimonic 80A and Nimonic 90 belong to the family of nickel based super alloys and are widely used in high temperature applications. In this study, the effect of indentation load (10 to1000 gf) and dwell time (3to15 s) on the micro-hardness of Nimonic 80A and Nimonic 90 are investigated. A fuzzy logic predictive model is established to predict the micro hardness with respect to changes in the input parameters of indentation load and dwell time. The experimental results show a good degree of agreement with the fuzzy logic model, for both Nimonic 80A and Nimonic 90 with a minimum error %age of 3.05 and 1.80 respectively.
A Modeling Paradigm for Product Specific Design Analysis Integration
Authors: Saini P K 
Published: August 2019

Abstract
In spite of recent advancements in computer aided design and engineering (CAD/CAE), such as parametric geometry and automatic mesh generation, a large gap exists between computer based design model and analysis model. In this paper, a new product specific approach to integrate design and analysis integration is proposed. The primary objective of this approach is to capture designer’s intent from the limited interaction with the designer in a language that is familiar to designer and to provide the feed back on the suitability of the design based on the finite element analysis (FEA) so that the design is automatically and iteratively modified. Hence, the proposed modeling paradigm provides capabilities of analysis to the designer and acts as a black box without requiring the designer to possess relevant knowledge of FEA. Priority has been given to the class of problems termed as routine analysis – the regularly used, established analysis model in the product design. A representative case study pertaining to Belleville spring is discussed in the context of the proposed methodology to demonstrate that it enables highly automated routine analysis through FEA for the model.

Published: August 2019

Abstract
A modified vapor compression refrigeration system using ejector as an expansion device has been studied in this paper. The new system gives higher cooling effect and requires lesser compressor work than typical vapor compression system under similar operating conditions. Exergy analysis has been done to determine the scope of performance improvement in various components of the modified system. Three refrigerants namely R134a, R407C and R410A have been taken for the analysis due to their wide usage in the commercial refrigeration and air conditioning systems. The system is found to have highest 2nd law efficiency of 53.32% with R134a at 35°C condenser temperature and 5°C evaporator temperature. The increase in condenser temperature increases the total irreversibility of the system. The maximum exergy destruction has been observed in condenser for all the refrigerants. The analysis has been carried out in Engineering Equation Solver.

Published: August 2019

Abstract
Corrosion occurring at elevated temperatures is a serious problem in areas such as gas turbine applications and power plants that use high temperature boilers. In this paper, we carry out experimental investigation for reducing corrosion rate so as to enhance the corrosion and wear characteristics of 347HSS and quantify the effect of 75Ni25Cr on 347HSS in terms of improved corrosion resistance. A coating of 75Ni25Cr was deposited on 347HSS boiler tube by the process of Detonation Gun. Corrosion studies were conducted on bare as well as D-Gun coated 347H stainless steel specimens in air and simulated husk fired boiler atmosphere at 800°C under cyclic conditions. Each cycle consisted one hour of heating in the tubular furnace and 20 min of cooling at room temperature. Fifty such cycles were completed to observe performance of these specimens. The weight change measurements were performed after each cycle to establish the kinetics of corrosion using weighing balance. Scanning Electron Microscopy, X-ray diffraction and X-ray mapping analysis techniques were used to analyse the corrosion products formed on the surface of these substrates.

Published: August 2019

Abstract
Tea is one of the primary beverages consumed with its added health benefits. India enjoyed supremacy in its production till a significant period. But, recently it is lagging behind in the race being surpassed by some neighbouring countries. The aforesaid issue is a matter of serious concern as it has a major share to contribute in the Gross Domestic Product (GDP) of the country and hence is a sizeable foreign exchange earner. The effect has arisen due to lack of varieties and cumbersome approach to the production of tea. Hence, this paper focuses on Computer Integrated Manufacturing (CIM) of tea industry which leads to automated production and scope of implementation of mixed assembly lines, thereby increasing the scope of the global market capture of sales. The automation is designed on Programmable Logic Controller (PLC) based control of the CTC (Crush, Tear & Curl) tea manufacturing processes. The user interface has been proposed to be developed with the help of a SCADA software. The interfacing of PLC and SCADA can be achieved by OPC communication. Virtual commissioning of the entire production line can be achieved by plant simulation.

Published: August 2019

Abstract
In this era of technological development, greater impact of nanotechnology now can be seen in many fields due to better properties and precise control. Many functions are being executed by bio nano-materials or biomolecules in living systems in a very efficient manner. The functional behaviour and their properties need to be examined to use them for various nano-device applications. The mechanical properties of the biomolecules can be studied by attaching them with microspheres and measuring forces on these microspheres through optical trap. Microspheres of three-micrometer diameter were trapped at the focus of infrared laser and viscous drag forces were applied to measure the effect of these forces on the trapped microsphere. It was observed that with 28mW intensity Laser, the trapped microsphere was displaced by 0.19 μm at 2.1 pN force and trap stiffness was determined as 0.011pN/nm. The findings can be useful while attaching these microspheres as cargos along the bionanomotors for nanorobotics and drug delivery applications.

Published: August 2019

Abstract
The strategy of agile supplier selections (ASS) process has adopted the recent era due to global competitive edges in a rapidly changing business environment. The sustainable agile performance criteria are the key necessity for market variations and more customer responsiveness. Therefore, the adaptation of ASS process is a key requirement to overcome the market variations and influence by number’s criteria. ASS is a major issue in Supply Chain Management (SCM), due to various uncertainties of market demand, lumpy demand, mismatch of supply and demand patterns, in these causes’ selection of supplier procedure is a difficult task in the automotive industry. Due to volatile market demand and more customer responsiveness, it is stimulating that inter-organization to balances the effective and efficient customer needs in volatile market demand patterns. This problem will be resolved by incorporating with human judgment skill capability in linguistic scale patterns. ASS has employed such method as the Fuzzy logic and DEMATEL approaches to perform better in global competitiveness. It strives to sustain the volatile market demand by appropriate ASS performance criteria. With the help of the literature survey, 14 agile supplier selection criteria have selected for better influence or support for ASS procedures.
Thermodynamically optimal creation of correlations

Published: August 2019

Abstract
Correlations lie at the heart of almost all scientific predictions. It is therefore of interest to ask whether there exist general limitations to the amount of correlations that can be created at a finite amount of invested energy. Within quantum thermodynamics such limitations can be derived from first principles. In particular, it can be shown that establishing correlations between initially uncorrelated systems in a thermal background has an energetic cost. This cost, which depends on the system dimension and the details of the energy-level structure, can be bounded from below but whether these bounds are achievable is an open question. Here, we put forward a framework for studying the process of optimally correlating identical (thermal) quantum systems. The framework is based on decompositions into subspaces that each support only states with diagonal (classical) marginals. Using methods from stochastic majorisation theory, we show that the creation of correlations at minimal energy cost is possible for all pairs of three- and four-dimensional quantum systems. For higher dimensions we provide sufficient conditions for the existence of such optimally correlating operations, which we conjecture to exist in all dimensions.

Published: August 2019

Abstract
This research aimed to study the effect of citric acid on production performance of laying Japanese quail. One hundred of 12 weeks laying Japanese quails were divided into 4 treatments and 5 replication based on completely randomized design. The treatments were citric acid addition level, they were 0, 0,3, 0,6, and 0,9% of citric acid. This research used a self-mixing feed that contained 2800 kcal/kg metabolizable energy and 17,5% crude protein. The parameters measured were feed consumption, egg weight, egg production, and feed conversion ratio. The obtained data during 4 weeks measurement were analyzed using variance analysis and continued with Duncan’s Multiple Range Test. The result showed that addition of citric acid on Japanese quail feed did not give any significant effect (P>0,05) on feed consumption and egg weight, but the addition of citric acid gave a significant effect (P<0,05) on egg production and feed conversion ratio. During 4 weeks, addition 0,6% citrit acid showed egg production above 75%. It can be concluded that addition of 0,6% citric acid showed a better egg production and feed conversion ratio performance.

Abstract
Avian Influenza (AI) in poultry farms in Indonesia is still a threat to the sustainability of livestock and farmers. Duck is one of the most heterogeneous natural reservoirs and hosts of AI viruses. This study aims to detect antibody titer AI levels in blood serum and duck eggs as well as to know the different hematology profile of Tegal and Magelang ducks in Central Java. Research method was survey at farmer level. Farmer and duck samples were determined by purposive random sampling of 10 breeders for each region. Selection of respondents and ducks was based on the number of duck owners and duck age. The samples of farmers and ducks taken were determined randomly as many as 10 breeders in each area and from each breeder was selected 6 female ducks for their blood and 10 eggs to be analyzed using antibody titer against AI. The variables measured in this study were antibody titer against AI measured on blood serum and serum egg yolk, with inhibition hemagglutination test and haematological profile. The data obtained were analyzed using T-test. The results showed protective antibodies against AI on blood serum Tegal ducks (seropositive) 58% while Magelang ducks 46%. Titer of serum antibodies of Tegal duck in the range of 22-25 while Magelang ducks 22-26. Titer of egg antibody in Tegal ducks in the range of 20-210 while Magelang ducks 20-27. T-test on AI antibody titer on blood serum and serum of eggs of Tegal duck and Magelang ducks (which have different environment) showed no significant difference (P> 0.05). The result of T-test on leukocyte fraction profile showed that on heterophile, lymphocyte, and H / L both ducks showed a very significant difference (P <0.01). Higher H / L values in Tegal ducks show stress due to heat stress. T-test on red blood cells, white blood cells, hemoglobin, packed cell volume (PCV), total plasma proteins, eosinophils, monocytes, fibrinogen and albumin showed no significant difference (P> 0.05). The study concluded that there was no difference of antibody titer level to AI and hematology profile in Tegal and Magelang ducks despite different maintenance environment. However, Tegal duck was indicative of higher stress with higher H / L values than Magelang duck.
