This paper aims at the modeling and control strategy for an integrated renewable energy system (RES). A decentralized power generation in the form of integrated system is proposed comprising of a photovoltaic (PV) system and a wind energy system (WES) to supply required electric loads. The PV system is sculpted with a DC/DC converter for regulating DC output voltage; a maximum power point tracking system (MPPT) is amalgamated in order to achieve a reliable power output. The WES is modeled with a variable speed wind turbine, permanent magnet synchronous generator (PMSG) and DC/DC converter. Both the sources are integrated and connected to a common DC bus and PI controller would be used to track the maximum power in photovoltaic and wind energy system. The method to be simulated using Matlab/Simulink.

The Linear energy harvesters and actuators employ electromagnetic induction principles to generate electrical energy or motion. The most common configurations for such actuators are cylindrical ring magnets with coils inside or cylindrical magnets with coils surrounding the magnets. A series of numerical FEA analyses were performed to design and simulate different core-ring magnet configurations to identify the best possible combination for maximum energy transduction. It was observed that the tapered ring magnet - tapered core configuration had the highest magnetic spatial variation and thus suitable for maximum energy transduction. This study can be applied to design linear actuators, linear electromagnetic energy harvesters and from microscale to macroscale applications.

The heat recovery duct of Window air-conditioning unit is simulate to recover the waste heat from the condenser and uses the same for drying the kitchen food waste. The combination of convergent and square duct is used for heat recovery. The artificial roughness is created on the heat transfer surface to enhance the heat transfer. The ribs were attached to the wall perpendicular to the direction of flow. The local heat transfer and pressure drop characteristics of hot air through plain and ribbed duct have been investigated by experimentally as well as numerically for Reynolds number of 42,305. The numerical thermal performance of heat recovery system for plain and ribbed duct has been compared with that of the experimental. The comparison shows that, because of the ribs the thermal performance of the system is increases by 28%.

In this paper, the grid connected solar photovoltaic (SPV) power plant of L&T construction, Phagi, Jaipur, Rajasthan, India is presented and its performance is evaluated. This power plant has a capacity of 1 MW and has been in operation since March 2012. In this paper various performance parameters such as Performance ratio, reference yield, array yield, final yield of array are calculated using three different methods: namely Excel sheet, PV-syst, System Advisory Model (SAM). The monthly performance ratio ranged from 53% to 83% and annual performance ratio keeps on increasing due to grid availability. After obtaining power generation data and meteorological data from the site of the plant for three consecutive years of 2013, 2014 and 2015 the calculation is performed. Values of Performance parameters obtained from all the three methods are in close agreement. Levelized Electricity Cost has been calculated for the plant based on the power generated values during these years.

A new methodology for the detection of insulator arc faults for the smart grid environment based on phasor angle measurements is presented in this study and the real time phase angle data are collected using Phasor Measurement Units (PMU). Detection of insulator arcing faults is based on feature extraction and frequency component analysis. The proposed methodology pertains to the detection of insulator arcing faults in transmission lines network based on leakage current, frequency characteristics and synchronous phasor measurements of voltage. The methodology is evaluated for IEEE 14 standard bus system by modeling the insulator arc faults and smart grid using MATLAB/Simulink. The proposed methodology using phasor angle measurements using PMU is used for fault detection of insulator arcing which further helps in efficient protection of the system and its stable operation. In addition, the methodology is suitable for wide area condition monitoring of smart grid rather than end to end transmission lines.

The rocket engines are tested statically to evaluate the performance of engine based on thrust produced. One of the most important parameters of the rocket engine static testing evaluation is to measure the thrust produced by the engine. The thrust produced is measured using a Thrust Measurement System (TMS) which is a structural element equipped with load cells. The upward movement due to the thrust developed by the rocket engine is felt through the load cells and its linkages. This project is aimed at designing and analyzing the TMS. The various configurations of the TMS for a heavy thrust semi cryogenic engine are planned. TMS consists of structural elements and load cell link assembly so as to measure and transfer the thrust to the test stand structure. This project is aimed at structural design using Creo and analysis of a structural configuration using ANSYS v12.1 to meet the TMS requirements.

The green cloud computing is the evolving area in which multiple datacenters are placed in different location for providing data and service to customer and users worldwide. The various performance measures for the efficient cloud computing data center are (PUF) Power Usage Factor, (DCiF) Data center Infrastructure Factor, (CPF) Compute Power Factor, (GEF) Green Energy Factor, (ERF) Energy Reuse Facility, (ECUF) Effective Carbon Usage factor, (WUF) Water Usage Factor, (DCPF) Data Centre production Factor, (DCePF) Data Centre Energy Production Factor, (SWaE) Space, Wattage and Effectiveness. The performance measure and data center servers has gained more importance due to cost effectiveness and customer satisfaction. However customer disagreement can be cause if performance measure is not provided by the data center as specified in SLA. In this paper we present an effective collaborative way to measure the various performance of the datacenter through a collaborative real-time mobile apps on smart phone. The Mobile apps can effectively provide interaction between customer and data center.

Maximum power point tracking is a method to trap maximum available power from a solar panel. Many algorithms have been developed based on the characteristics of solar panel in order to utilize maximum available power. But these algorithms do not consider local maxima and minima in the solar panel characteristics caused due to shading. In this paper an enhanced version of Perturb and Observe maximum power point tracking algorithm is explained which also considers local maxima and minima caused by shading and makes the solar panel to work at its peak maxima. This helps in improving the overall efficiency of the system. Algorithm is implemented on 50W solar panel using ATMega 8 microcontroller and a boost converter.

The effect of process and temperature variations are becoming more dominant with technology scaling, especially for RF circuits, wherein even the minute variability in FETs and passive devices have a significant impact on the overall circuit behavior. Due to stringent power and performance specification requirements in the latest Wireless/RF applications, reasonable compensation for the process, voltage and temperature variations, is even more critical. In this paper, the design of a 2.4GHz operated, ultra-low power CMOS down-converting active mixer fabricated in standard 180 nm RF CMOS technology has been presented. The mixer is based on double balanced Gilbert-cell resistor-loaded topology. The effects of process and temperature variations on the designed mixer have been investigated and various compensation techniques relevant to the current design have been analyzed.
