A Study on Potentiality of Silver as an Investment Asset

In the last few years the countries around the world are facing burden of global economic slowdown and the same is indicated in their slower GDP growth and falling stock market prices. Even under these precarious conditions the commodity markets are experiencing considerable growth and are offering good returns to the investors. Among all commodities, though considered as highly volatile, silver is a very attractive commodity to invest. In contrast to the common belief, silver is relatively a safe investment in the long run and assures significantly high returns to the investors. The present study aims to prove potentiality of silver as an investment asset using simple risk, return analysis and other basic fundamentals. The results of the analysis prove that silver is a good asset for investment vis-à-vis gold and stock markets and is a consistent performer under different economic conditions

Surface Morphological Studies of Solar Absorber Layer Cu2ZnSnS4 (CZTS) Thin Films by Non-vacuum Deposition Methods

Surface morphological studiesThe consumption of fossil fuel globally has been enormous and has reached an alarming rate resulting in fast depletion of the available resources and at the same time polluting the environment. Hence there is a growing need to take cognizance of abundant amount of inexpensive energy available in the nature especially solar energy. Development and commercialization of Photovoltaics has been in focus due to its low cost, high absorption coefficient and suitable direct band gap for solar energy conversion applications. An attempt has been made in this work to synthesize the CZTS thin films by Electro deposition and Sol-gel method on Indium Tin Oxide (ITO) glass and Soda Lime Glass( SLG) substrates respectively. CZTS thin films have been prepared using a 3-stage electro chemical system wherein the precursors are deposited using platinum foil as a counter electrode and AgCl electrode as a reference electrode and Sol gel method. Surface morphology and optical properties have been studied using Atomic Force Microscopy, Scanning Electron Microscopy, X-ray Diffractometer and UV-Vis Spectroscopy When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/3596

Community and Law Enforcements in Preventing Elderly Abuse – Critical Analysis on Human values in India

Nowadays people are confined with life style of stress, adjusted and isolated dramatically to the progressive dimension of stressful life in working condition, property, status, wealth. On the other end somewhere people are being suppressing the humanistic approach of the natural human tendencies, humanity and human values. Socialization makes man civilized, but some sort of attitudes is forcing society into innumerous social problems. In that, violence’s, abuses are undoubtedly mixed up as a part of the livelihood. In that main concern on elderly abuse and neglecting old people is terribly considered to be violence against elders. The gerontology and its values are more concern in recent development. The 21st century is designated as “Century of elderly person”. There are various reasons to know about the elderly people and their problems also their condition, physically, socially, economically, and psychologically. The role of Law enforcements is to work for prevention of violence by influencing and implementing various legal factors in order to prevent also in order to look upon the conditions. The present existing laws in regardence with elderly abuse ,and other form of domestic violence’s and their present impact on the society, preventive measures and break down of human values are critically made analysis, discussed in this paper by various secondary sources like reports of institutes, surveys and also in consideration of existing law and community services

Efforts towards the Detection of Perturbations in the Earth’s Magnetic Field: Design and Development of Solid State Sensor Array

The following thesis provides a detailed description of the design and development of magneto-resistive unexploded ordinance (UXO) sensor array to detect the perturbations in the Earth’s magnetic field due to the presence of buried ferrous objects. Over the years there has been a substantial development in the detection of unexploded ordinance. The objective of this research is to use the multiple axis sensors in the design to detect UXO. This thesis describes the theory of different magnetization techniques and the characteristics of Anisotropic Magneto-Resistive (AMR) sensors. The description of each hardware component employed in the system is given in detail. The softwares used for the data handling and processing is also addressed. The verification of a working design is achieved by acquiring baseline data set

Multi-objective wind farm layout optimization using evolutionary computations

The usage of fossil fuels is actually not good for living nature and in future, this limited source of energy will vanish. Therefore, we need to go with the clean and renewable source of energy such as wind power, solar energy etc. In this paper, we are concentrating in wind power through optimizing the wind turbine placement in wind farm. The area-of-convex hull, maximize ‘output power’ and minimum spanning tree distance are our main objective topics, due to their effect in wind farm design. An implementation of modified version of the wind turbine (WT) placement model is uses to estimate the yields of the (wind farm) WF layouts and for simplifying the behavior of wind field, in this paper we uses a simple wake approach. Moreover, to resolve the multi-objective problem here we proposed (Modified Genetic Algorithm) MGA, which is considerably better than the (Genetic Algorithm) GA and for evaluate the performance of MGA we use the multi-objective (EA) evolutionary algorithms such as; Genetic algorithm (GA) and SPEA2 and, produce different number of WT layouts. These methodologies are consider with various ‘problematic specific operators’ that are present in this paper

A Novel Low Power-Application UPS consisting of an APF - Correction circuit & integrated Battery-Management system

For the up-coming generations of power-supply systems, the load located area power-supply sources are an effective one, in terms of our requirements: simplicity, integrity, battery-backup, etc. This could follow the Normalization of power factor & Reducing THD% values on input current, which makes us to add an essential to include a power-factor correction unit at supply side in these new typical topologies. This Proposed architecture presents an integrated battery manage system which can also offers PF correction along with Galvanic-Isolation of battery in a humble single structure. [3] The proposed scheme has the reliable characters like increased efficiency, compact circuit and reduced costs associated with a traditional standalone multiple-stages UPS with PFC. This paper addresses the UPS action, the analysis and simulation results of Proposed UPS scheme
