This paper deals with the fabrication of ZrO2, Al2O3, ZrO2/Al2O3 and Al2O3/ZrO2 coatings on 304 stainless steel substrate by atmospheric plasma spraying. The microstructure and phase composition of the as-sprayed coatings were examined by scanning electron microscopy and X-ray diffraction. Hardness measurements were carried out using a Vickers hardness testing machine. Corrosion behaviour of the coatings was studied by salt spray testing in a mist of 5 wt% NaCl. Results indicate that the bilayered Al2O3/ZrO2 coating exhibits superior corrosion resistance when compared with that of the other coatings and this is ascribed to the presence of dense microstructure with very few pores in the coating. © 2015 Indian Ceramic Society.

The microstructure and mechanical behavior of beta titanium alloy Ti-15V-3Cr-3Al-3Sn (Ti15-3) under unidirectional and high cycle fatigue (HCF) loading conditions were studied after single aging (SA) and duplex aging (DA). After SA, well-developed grain boundary α and micro precipitate free zones (micro PFZs) were present in the microstructure. Whereas after DA, grain boundary α was poorly developed and micro PFZs were absent. DA resulted in smaller size, higher density and volume fraction of alpha particles. DA led to higher work hardening rate, better strength-ductility combination and higher HCF life. Improved mechanical behavior after DA is explained based on microstructural observations. © 2014 Elsevier Ltd. All rights reserved.

Effect of duplex aging on microstructure and mechanical behavior of beta titanium alloy Ti–15V–3Cr–3Al–3Sn under unidirectional and cyclic loading conditions

Currently more than 1 billion adults are overweight -and at least 300 million of them are clinically obese. Article from World Health Organisation mentioned that obese is the major cause for Diabetics, cardio vascular problem and cancer. Change in food habits and lack of physical activities are the main reason for obese. Daily food choices affect our short term and long term health. By monitoring food intake we can assess the person food habit, in this paper we discussed and analyse various method involving energy intake and energy expenditure and need for accurate long term dietary assessment technique for free living individuals. © 2015 IEEE.

Moisture content [MC] in food items should be tracked at right time with high precision as it is important for processing and storage of food items. Moisture content in some of the food grains has to be reduced to avoid its damage. In this paper we go through different techniques used to measure MC in different food grains. There are destructive and non-destructive methods to measure MC. In destructive method peanuts or samples have to be cleaned and shells are removed, so that this method is time consuming and samples are wasted. In this paper we study different non-destructive technique, to measure moisture content in which grains or food items can be directly used without any process like cleaning or crushing. Time taken to measure moisture content using this method is less. © 2015 IEEE.

Abstract The influence of thermo-mechanical processing (TMP) on the microstructure and the electrochemical behavior of new metastable β alloy Ti-20.6Nb-13.6Zr-0.5V (TNZV) was investigated. The TMP included hot working in below β transus, solution heat treatments at the same temperature and different cooling rates in addition to aging. Depending upon the TMP conditions, a wide range of microstructures with varying spatial distributions and morphologies of equiaxed/elongated β and β phases were attained, allowing for a wide range of electrochemical properties to be achieved. The corrosion behavior of the studied alloy was evaluated in a Ringer's solution at 37 °C via open circuit potential-time and potentiodynamic polarization measurements. © 2015 The Nonferrous Metals Society of China.

Electricity theft is a common practice in developing countries which cannot be controlled by the governments due to lack of technology. Emerging trends such as Automatic Meter Reading (AMR) eliminate the need of person visiting each house but this advancement further increases Non-Technical losses (NTL) because of no regular inspection at the residence. However traditional meter reading by human operator is inefficient to meet the future residential development needs. This paper proposes a new system based on ARM-Cortex M3 processor to protect the energy meter from phase line bypassing, neutral line disconnection, whole meter bypassing and meter tampering. A SMS automatically send to utility server through Global System for Mobile (GSM) network when these measures detected. In this paper a novel method is proposed to solve the problem with AMR systems without affecting its major advantage of remote monitoring. Integrating this new feature into smart meters provides a robust metering solution. © 2015 IEEE.

The power quality of interconnected grid is highly affected by the non linear loads and the interconnected renewable energy sources like wind and solar systems. The drastic changes in their input effectively change the grid parameters. This paper provides a novel method in which compensator continuously monitors the line parameters like voltage, currents, harmonics and reactive power to maintain the desired values at common connecting line (CCL). This paper utilizes the capabilities of hybrid Fuzzy and ZN PID Controlling of Dynamic Active Power Filter (DAPF) along with the Energy storage at dc link. The proposed model simulated in MATLAB/SIMULINK and at the grid common connecting line, the power factor and Total Harmonic Distortion values are much improved. © 2015 IEEE.
