Abstract The temperature reached by solar cells/modules during operation has been simulated to have information about the temperature distribution in the solar cell/module. A finite element (FE) model of the solar cell/module was created in COMSOL Multiphysics environment. The simulations enable visualization of the temperature distribution in crystalline silicon solar cell. The effect of different encapsulating materials, Ethylene-vinyl Acetate (EVA) and silicone on cell temperature are also investigated. An unwanted side-effect of the encapsulation of solar cells into a PV module is that the encapsulation alters the heat flow into and out of the PV module, thereby increasing the operating temperature of the PV module. These increases in temperature have a major impact on the PV module by reducing its voltage, thereby lowering the output power. A finite element (FE) model representing a real crystalline silicon solar cell/module in terms of size, mechanical and material properties is created. An in-depth study of the FE software used, COMSOL Multiphysics is done in other to get the best output in terms of solver configuration and memory considerations. Four different geometries of the solar cell/module are created for these simulations; each representing a stage or variant in the solar module assembly. At first, the models are validated comparing results from simulations such as the effect of changes in solar irradiance, wind velocity and incident angle of solar irradiance on temperature with those in literature. The effect of the type of protective cover used in the encapsulation, either glass-glass or glass-Tedlar on cell temperature is analyzed. The thickness of the protective cover layers and its optical properties are also investigated based on their effects on cell/module temperature. All the simulations leading to the conclusions drawn about the cell/module temperature and its distribution were performed by varying wind velocity, irradiance, material sizes and incident angle among other model modifications. The color maps and graphs are presented in this study. Key Words: Modeling, COMSOL Multipysics, Crystalline silicon solar cell/module, FE simulations, Temperature

This document describes the design and development of a low-cost thermoelectric generator module that converts waste heat into electricity. The module uses the Seebeck effect to induce electricity from a temperature difference between aluminum and graphite strips. Several iterations were tested with improvements like clearer contact points between materials, more couples per slide to produce more power, and variations in strip widths and heights. Testing in an oil bath showed increased voltage output with greater temperature differences applied across the couples. The results demonstrate this simple module's potential as an efficient, renewable energy source from normally wasted heat.
In modern days, the use of energy consumption increasing very rapidly. Fossil fuels are finite and environmentally costly. Sustainable, environmentally benign energy can be derived from nuclear fission or captured from ambient sources. Large-scale ambient energy (eg. solar, wind and tide), is widely available and large-scale technologies are being developed to efficiently capture it. At the other end of the scale, there are small amounts of ‘wasted’ energy that could be useful if captured. Recovering even a fraction of this energy would have a significant economic and environmental impact. This is where energy harvesting (EH) comes in.
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to show how energy harvesters are becoming more economically feasible for the Internet of Things (IoT). Small amounts of energy can be harvested from vibrations, temperature differences, and radio frequencies using various types of electronic devices such as piezoelectric, MEMS, thermo-electric power generators, and other devices. As improvements in them occur and as the energy requirements of accelerometers, pressure sensors, gas detectors, bio-sensors, and readout circuits fall from microwatts to hundreds of nano-watts, energy harvesters become cheaper and better than are batteries. Improvements in energy harvesting are occurring in the form of higher power per area or higher power per temperature difference and improvements of about five times are expected to occur in the next 5 to 10 years. The market for energy harvesters is expected to reach $2.5 Billion by 2024. In addition to their impact on buildings and the other usual applications for IoT, they will also impact on agriculture, aircraft, and medical implants.

Theoretical and Experimental Investigations of a Non-linear Single Degree of ...Rathish Chandra Gatti,Ph.D
There is an increasing need for sensors to be selfpowered
and hence autonomous in order to operate in remote and
inaccessible locations for long periods of time. Amongst the
various ambient sources of energy, mechanical vibration is a viable
wasted source of energy and can be found in rotating equipment
including generators, motors and compressors as well as
structures including bridges. The current research deals with
developing a novel non-linear single degree of freedom
electromagnetic vibration energy harvester using spatial variation
of the magnetic field.
Initially, approximate linear methods using Laplace transforms
and the linear state space methods were considered, where the
magnetic field and hence the coupling coefficient were considered
as constants. The linear methods were used to derive the frequency
response behavior of the system and also its eigenvalues to
determine the approximate resonant frequency range. This was
followed by more accurate non-linear single degree of freedom
electromagnetic energy harvester model simulation considering
the spatial variation of the magnetic field and hence a spatially
varying coupling coefficient. An experiment of the single degreeof-
freedom one-direction electromagnetic vibration energy
harvester (SDOF1D EMVEH) prototype was conducted for a
range of frequencies to obtain the time domain data to validate
against the theoretical data obtained from theoretical time domain
simulation.
The document describes the design and working of a solar air cooler. It consists of the following main components: solar panels that convert sunlight to electricity, a battery that stores the solar energy, a DC motor powered by the battery, an impeller connected to the motor, and a DC water pump. During operation, the solar panels charge the battery with electricity. The DC motor runs the impeller blades and water pump which sprays and circulates cold water, producing a cold air stream. Together these components form a solar-powered air cooling system that reduces electricity usage compared to conventional air conditioners. The total estimated cost to build this solar air cooler is 5,200 INR.
Photovoltaic (PV) power harnesses sunlight to generate electricity and has the potential to serve as a viable national energy source. PV cells use semiconductors that generate a direct current when exposed to sunlight, which is then converted to alternating current and transferred to power grids. While initial costs remain high, technology innovations have increased efficiencies and reduced prices. Widespread adoption of PV power would help reduce greenhouse gas emissions and dependence on foreign oil while taking advantage of the nation's solar energy potential. However, challenges around energy storage and developing infrastructure for solar at a national scale remain.
The document discusses maximum power point tracking (MPPT) using the perturb and observe method. MPPT is a technique used in solar panel systems to extract the maximum available power from the panels by matching the panel voltage to the maximum power point on its power-voltage curve. The document provides background on renewable energy and solar power generation. It then describes modeling a solar panel as a current source and diode, and explains how solar panel characteristics change with insulation and temperature. The key goal of MPPT is to continuously track the maximum power point of the solar panel as conditions vary.

various ambient sources of energy, mechanical vibration is a viable
wasted source of energy and can be found in rotating equipment
including generators, motors and compressors as well as
structures including bridges. The current research deals with
developing a novel non-linear single degree of freedom
electromagnetic vibration energy harvester using spatial variation
of the magnetic field.
Initially, approximate linear methods using Laplace transforms
and the linear state space methods were considered, where the
magnetic field and hence the coupling coefficient were considered
as constants. The linear methods were used to derive the frequency
response behavior of the system and also its eigenvalues to
determine the approximate resonant frequency range. This was
followed by more accurate non-linear single degree of freedom
electromagnetic energy harvester model simulation considering
the spatial variation of the magnetic field and hence a spatially
varying coupling coefficient. An experiment of the single degreeof-
freedom one-direction electromagnetic vibration energy
harvester (SDOF1D EMVEH) prototype was conducted for a
range of frequencies to obtain the time domain data to validate
against the theoretical data obtained from theoretical time domain
simulation.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.
APPLICATION OF FRUGAL APPROACH FOR PRODUCTIVITY IMPROVEMENT - A CASE STUDY OF...IAEME Publication
Manufacturing industries have witnessed an outburst in productivity. For productivity improvement manufacturing industries are taking various initiatives by using lean tools and techniques. However, in different manufacturing industries, frugal approach is applied in product design and services as a tool for improvement. Frugal approach contributed to prove less is more and seems indirectly contributing to improve productivity. Hence, there is need to understand status of frugal approach application in manufacturing industries. All manufacturing industries are trying hard and putting continuous efforts for competitive existence. For productivity improvements, manufacturing industries are coming up with different effective and efficient solutions in manufacturing processes and operations. To overcome current challenges, manufacturing industries have started using frugal approach in product design and services. For this study, methodology adopted with both primary and secondary sources of data. For primary source interview and observation technique is used and for secondary source review has done based on available literatures in website, printed magazines, manual etc. An attempt has made for understanding application of frugal approach with the study of manufacturing industry project. Manufacturing industry selected for this project study is Mahindra and Mahindra Ltd. This paper will help researcher to find the connections between the two concepts productivity improvement and frugal approach. This paper will help to understand significance of frugal approach for productivity improvement in manufacturing industry. This will also help to understand current scenario of frugal approach in manufacturing industry. In manufacturing industries various process are involved to deliver the final product. In the process of converting input in to output through manufacturing process productivity plays very critical role. Hence this study will help to evolve status of frugal approach in productivity improvement programme. The notion of frugal can be viewed as an approach towards productivity improvement in manufacturing industries.
A MULTIPLE – CHANNEL QUEUING MODELS ON FUZZY ENVIRONMENTIAEME Publication
In this paper, we investigated a queuing model of fuzzy environment-based a multiple channel queuing model (M/M/C) ( /FCFS) and study its performance under realistic conditions. It applies a nonagonal fuzzy number to analyse the relevant performance of a multiple channel queuing model (M/M/C) ( /FCFS). Based on the sub interval average ranking method for nonagonal fuzzy number, we convert fuzzy number to crisp one. Numerical results reveal that the efficiency of this method. Intuitively, the fuzzy environment adapts well to a multiple channel queuing models (M/M/C) ( /FCFS) are very well.
