Food quality is the quality properties of food that is acceptable by consumers. This includes important factors as appearance texture, and flavor. food consumers are affected to any form of contamination that may occur during the manufacturing process. Many consumer give importance to standards of processing and manufacturing, mainly to know what ingredients it contains, because of dietary, nutritional requirement, or medical conditions. Our proposed system may give the good quality management in food. It is based on many embedded sensors like thermostat, odour sensor, biosensor, pH sensor depending on out coming electric signals or digital value quality of the food should be determined. But the biosensor play a vital role to detect the bacterial contamination in food sample. Based on the combination of the sensor outputs quality of the food should be detected. © 2016 IEEE.

In recent days, our way of living has been changed more, lead to health consciousness, so health monitoring system is most important part of our life. In this proposed method, an RTOS based Wireless Sensor Network architecture has been developed for the health monitoring. One node acts as central and the others will be a slaves which are used for data acquisition. Data acquisition node uses the Peripheral Interface controller. Communication between two nodes are accomplished through IEEE 802.15. The RTOS is used to allocation resources to users in an orderly manner. The RTOS based technique is to reduce the possibility of collision. This is done by using ARM controller in KEIL and also OrCad tool for schematic design. © 2016 IEEE.

In this paper, impact of the tool geometry on the mechanical properties of AZ80A Mg alloy by employing different axial forces during friction stir welding (FSW) was investigated. Mechanical properties of the friction stir welded joints were analyzed and harmonized with the FSW zone microstructural characteristics. It was observed that joints produced using taper cylindrical pin profiled tool under a 3kN axial force exhibited defect free weldments (metallurgically)with superior mechanical properties. Moreover, ideal level of heat generation and formation of grain structures with uniformlydistributed & finely refined grains in the zone of FSW are found to be the dominant reasons for the formation of flawless joints with superior mechanical properties. © 2017 Elsevier Ltd.

Multispectral remote sensing images are the primary source in the land use and land cover (LULC) monitoring. This is achieved by LULC classification and LULC change detection. The change detection in LULC includes the detection of water bodies, forest fire, forest degradation, agriculture areas monitoring, etc. Various change detection and LULC classification methods have their own advantages and disadvantages, and no single method is optimal and finds applicability for all cases. This paper summarizes and analyses the various soft computing and feature extraction techniques used for LULC classification and change detection. Based on the average error rate, performances of the different soft computing techniques are evaluated. The broad usage of multispectral remote sensing images, object-based change detection, neural networks and various levels of image fusion methods offer more potential in LULC monitoring. © 2017 CIMNE, Barcelona, Spain

Solar thermal power plants using dish-engine systems have conventionally used multiple dishes of an optimum size. In a few recent developments, dish sizes up to 500 m2 have been attempted in order to scale up power generation. Although using very large dishes may have a few advantages, the cost implications need to be analyzed before implementing such designs. An optimum dish size may provide the key advantage for dish-engine power plants to compete with grid power, but determining it poses a serious challenge. As dish-engine power plants call for heavy investments, it becomes important to design dishes to endure excessive wind loads, to prevent an overnight obliteration. A simple cost model is presented in this paper, in which the structural problem is modeled mathematically and optimized for minimum cost subject to wind-load resistance constraints. This paper demonstrates how cost optimization can be used as an effective decision making tool for selecting the right dish size. The optimization results indicate that very large dishes of conventional designs may not be cost-effective if they have to withstand heavy wind loads. © 2017 Elsevier Ltd

In this paper, the effects of axial force on the mechanical properties of AZ31B magnesium alloy flat plates during the Friction Stir Welding (FSW) process were investigated by carrying out the tensile tests as per the American Society for Testing and Materials (ASTM) E8M-11 standards. The tensile test results indicated that the increase of the axial force greatly improved the tensile shear load (TSL) of the friction stir welded joints at a constant tool rotational speed of 800 rpm and welding speed of 50mm/min. Sound lap joints with low distortion, lack of cavity and high tensile strength were successfully obtained with an axial force of 5kN. However, the TSL of the friction stir welded joints decreased when the axial forces were 3kN and 4kN with the same constant tool rotational and welding speed. © (2014) Trans Tech Publications, Switzerland.

In this paper, a detailed experimental investigation was carried on the impact of the effects of tool pin and shoulder diameter in joining the Al 63400 aluminium alloy using FSW process. Flat plates of 6 mm thickness have been selected as the base material for obtaining single butt welded joints. The tool materials used for joining these base material plates are High Speed Steel (HSS) and High Chromium High Carbon Steel (HCHCr). This paper experimentally investigates and suggests the appropriate, suitable tool material & tool geometry for producing good quality welds in joining of Al 63400 alloy using FSW process. © (2014) Trans Tech Publications, Switzerland.

In the Present paper, the effects of axial force, rotational speed of the FSW tool, welding speed and shoulder penetration on various mechanical properties of Aluminium alloy 6063 butt joint produced by Friction Stir Welding have been analyzed. The mechanical properties ike tensile strength, Yield strength and % Elongation have been tested using 6 mm thickness plate. The tool used for conducting the experiment was Hot Die Steel (HDS). The welding quality can be improved by enhancing the mechanical properties and minimizing the defects. Hence, analysing & examining the mechanical or physical properties and other relevant significant factors would help to enhance the weld reliability. Tensile Strength (TS), Percentage of Elongation & Yield Strength (YS) of FSW Al 6063 alloy has been carried out under different processing condition using Taguchi's experimental design. An optimum result has been obtained using main effects plot using S/N ratio values. The rotation speed of the FSW tool has been found dominant factor for TS followed by feed and shoulder penetration. Shoulder diameter shows the least effect on TS compared to parameters like Percentage of Elongation & Yield Strength (YS). © (2014) Trans Tech Publications, Switzerland.

The conventional controller suffers from uncertain parameters and non-linear qualities of Quasi-Z Source converter. However they are computationally inefficient extending to optimize the fuzzy controller parameters, since they exhaustively search the optimal values to optimize the objective functions. To overcome this drawback, a PSO based fuzzy controller parameter optimization is presented in this paper. The PSO algorithm is used to find the optimal fuzzy parameters for minimizing the objective functions. The feasibility of the proposed PSO technique has been simulated and tested. The results are bench marked with conventional fuzzy controller and genetic algorithm for two types of DC/DC converters namely double input Z-Source converter and Quasi-Z Source converter. The results of both the DC/DC converters for several existing methods illustrate the effectiveness and robustness of the proposed algorithm. © 2014 Elsevier B.V. All rights reserved.

Abstract The optimization is an important role in the wide geographical distribution of electrical power market, finding the optimum solution for the operation and design of power systems has become a necessity with the increasing cost of raw materials, depleting energy resources and the ever growing demand for electrical energy. Using adaptive real coded biogeography-based optimization (ARCBBO), we present the optimization of various objective functions of an optimal power flow (OPF) problem in a power system. We aimed to determine the optimal settings of control variables for an OPF problem. The proposed approach was tested on a standard IEEE 30-bus system and an IEEE 57-bus system with different objective functions. Simulation results reveal that the proposed ARCBBO approach is effective, robust and more accurate than current methods of power flow optimization in literature. © 2015 Elsevier Ltd.
