Improving Analog Performance and Suppression of Subthreshold Swing using Hetero-Junction Less Double Gate Tunnel FETs

In this paper, we investigated a new device, Hetero-junction less (H-JL) Double Gate Tunnel Field Effect Transistors (DGTFET) with high-k. III-V semiconductor material (like InAs-Si) gives excellent performance when InAs uses at source side, because of low band gap of 0.36 eV it reduces the potential barrier height of source channel interface causing maximum carriers are fastly tunnel across the source to drain in ON state whereas Si, at the drain side as higher bandgap Of increasing the barrier height of drain channel interface causing lower quantum tunneling occur, as a result good ION/IOFF ratio.

The InAs-source JLDGTFET with high-k (Hfo2) at 20 nm channel length provide a tremendous characteristics with high ratio , a point subthreshold swing (SS) and average SS is at room temperature. The simulation study of proposed device is done using sentaurus tools.

A Novel Design of a 4 Bit Reversible ALU using Kogge-Stone Adder

Reversible circuits are one promising direction withapplications in the field of low-power design or quantumcomputation. However, no real design flow for this new kind ofcircuits exists so far. Significant contributions have been madein the literature towards the design of reversible logic gatestructures and arithmetic units, however, there are not manyefforts directed towards the design of reversible ALUs.

In thispaper, a novel programmable reversible Kogge-Stone adder ispresented and verified, and its implementation in the design ofa reversible Arithmetic Logic Unit is demonstrated. Then,reversible implementations of ripple-carry, Kogge-Stone carrylook-ahead adders are analyzed and compared in terms ofdelay. The proposed design consists of the reversible Fredkin,Feynman, MG, HNG, PG and RKSC gates. The performancecharacteristics analysis is carried out in Xilinx environment.

Hydrogeochemical Analysis and Quality Evaluation of Groundwater for Irrigation Purposes in Puri District,Odisha

The present study is carried out in the Puri district, Odisha, India to ascertain the suitability of groundwater for irrigation purposes. The parameters used to ascertain the suitability of groundwater for irrigation purposes are synthesized. The physico chemical observations used for the purpose were ; pH, electrical conductivity, total dissolved solids, calcium, magnesium, potassium, carbonate, bicarbonate and the irrigation indexing parameters calculated were, sodium adsorption ratio, residual sodium carbonate, magnesium adsorption ratio, permeability ratio and Kelly's ratio.

The parametric values obtained from present study shows margins of concentration ranges lies within the permissible limit which shows that as a whole ground water of the district is suitable for irrigation purposes. In most of the places the residual sodium carbonate, permeability index, Kelly ratio, magnesium absorption ratio exceeded or remain below its permissible limit. So the non-tolerant crops susceptible for less yield to high sodium content can be avoided in the area. Suitable recommended use of chemicals such as lime, sulphuric acid may be added to soil with pre crop irrigation for leaching.

Preparation and Characterization of Green Synthesis GO/Metal/metal Oxide Nano-composites Applied for Nano Fluid Applications - A Review

The reduced graphene oxide (RGO) was fabricated by modified Hummers and chemical reduction methods. CRGO was characterized by X-ray diffraction, Scanning electron microscope and Raman Spectroscope. The stability, zeta potential, thermal conductivity and rheological properties of the as-prepared nanofluids were systematically investigated using different experimental methods. Metal/RGO, metal oxide/RGO nano composite was prepared by Ultrafine and water dispersive approach. The obtained characterized with XRD, Raman Spectroscopy, FTIRs, and SEM. This method is that the diameter of nanoparticles decorated by rGO is in the range of 3-5 nm. Those results demonstrate an outstanding potential for the use of GO/Metaloxide/Metal nano-fluids as suitable replacements for the conventional fluids in heat exchanger applications.

Modeling and Simulation of Solar Photovoltaic System

Solar energy is a vital untapped resource in a tropical country like ours. The main hindrance for the penetration and reach of solar PV systems is their low efficiency and high capital cost. The efficiency of solar PV is very low. In order to increase the efficiency, Maximum Power Point Tracking (MPPT) techniques are to be undertaken to match the source and load property. These techniques are employed in PV systems to make full utilization of PV array output power. Recently, many MPPT algorithms of PV system have been proposed which depends on solar irradiation and temperature, but perturb and observe (P&O) and Incremental conductance algorithms are basic and most widely used.

This project firstly introduces a Mat lab Simulink of photovoltaic array. To achieve the maximum power point tracking the Incremental Conductance method and perturb and observed (P&O) method are used. These two algorithms are employed with PV model along with converter in Mat lab Simulink. Three different converter boost, buck boost and cuk converter are design according to requirement and used. Few comparisons such as voltage, current and power output for each different combination have been recorded.

A Review Paper on Solar Panel Based Smart Irrigation System using GSM Module

Solar powered smart irrigation systems are very useful for farmers.Solar energy has emerged as viable source of renewable energy over the past few decades and is now used for various applications such as emergency lighting, water heaters, and industrial application. It is a cheap source of energy. Thesystem consists of water pump which is solar powered with a moisture sensor used for automatic water flow control, light ambient sensor, Temperature sensorand GSM technology.It has mainly working in two modes i.e. manual mode and automatic mode.

We have provide a switch which controls that modeIn this RF transmitter and RF receiver will be used to operate the overall system. A polar single axis solar panel tracker is implemented andit has an adjustable horizontal motor controlled axisandfixed vertical axis. If 2 to 3 degrees of misalignment happens then the tracker will correct its position and prevents wastage of power by continuously running motor. The light intensity of the two LDR is compared and according to the higher intensity of LDR the rotation of solar panel is decided and it is adjusted.To prevent the panel from rotating 360-° the stepper motor will have overturn triggers.

A Review on Economical and Technical Analysis for Modelling of Hybrid Energy System

Energy demand is increasing day by day due to globalization and papulation. So that by using non-renewable sources we cannot reach this energy demand because of increased cost per generation. And also from these sources pollution occurs is also more. So that if we use renewable sources, we can meet this energy demand. This paper gives review on different optimization methods of HES such as by using Artificial intelligence methods, by using software tools, by ensuring maximum energy production from low cost energy sources, by using DSM strategy and by using hybrid models. Finally, comparison and results are discussed.
