INTRODUCTION A smart grid is a power network which is based on digital technology is used to supply power, via two-way digital communications. A smart grid system allows for monitoring, analysis, control and communication within the supply chain and helps improve efficiency, reduce energy consumption and cost, and maximize the transparency and reliability of the energy supply chain. The smart grid was introduced with the aim of overcoming the weaknesses of conventional electrical grids by using

CME 434 - Finite Element Analysis Project Title: Analysis of Chain Link By: Anuj Salke (UIN 660484908) Sujay Khamitkar (UIN 662253535) Problem Statement: To study the stresses that occurs in a chain link when it is subjected to loads and to verify the results analytically. The aim of the project is to calculate the stresses induced in a chain link analytically and verify if these results are same with the results obtained from ANSYS. We found that they are not exactly

COCKPIT AUTOMATION A Good Servant but a Bad Master Introduction 1. With the advent of modern technology, the use of computers has become inevitable in the completion and performance of a particular task. While automation has proven to improve the speed of completion of a job, it drastically affects the "operator" whose task shifts from being the "performer" to being the "observer". This is where the issue of "complacency" sets in. With this major revolution, one may ask if the introduction of

keep the imbalance. The solar panel is colored so that it is the darkest possible color so that it absorbs a lot of light. The team from University of Michigan is coloring it differently, but it only absorbs 1/3 the light. Wiring leads are used to direct energy from the solar panel to power something. Plexiglass can cover the panel to protect it from the weather, but tempered glass is safer because glass won’t have imperfections that refract light and build up. That could eventually lead to fire.

financial strength analysis, current ratio and quick ratio is evaluated here. 7.3.1 Current Ratio: The current ratio is basically the liquidity ratio which is calculated as current assets di-vided by the current liabilities of the company. It tells about the company financial position that how much assets of the company can fulfill the liabilities of the company in case if the company liquidates. Sports Direct has a current ratio of 2.3 while the industry average for the current ratio is 1.35 that is very

INTRODUCTION 1. INTRODUCTION 1.1 Fundamentals of capacitor Capacitor is very useful component in the field of engineering and it is used in various electrical and electronic circuitries. Capacitor stores energy in the form of electric field. Capacitor also known as condensers which stores energy when charge and release energy when discharge . There are different forms of capacitors which are used widely, but common thing about this all capacitors is that they are made of two conductors

This chapter focuses on AISI A2 material, its properties and composition. A brief explanation is provided about wire electrical discharge machining (WEDM) process, its process parameters and its various advantages and disadvantages. The knowledge of these will be beneficial in understanding the different effects of the process parameters of the WEDM on the response parameters. 1.5 NON-TRADITIONAL MACHINING In Conventional machining or traditional machining the tool required is harder than the work

in an independent way. In the suggested control scheme, the power calculation and harmonic abstraction are not required since the harmonics, unbalances, disturbances, and displacement would be compensated. The SAF has a current loop in order to make sure a sinusoidal grid current synchronized with the grid voltage. The PAF has a voltage loop in order to ensure a balanced controlled load voltage with small harmonic distortion. The SAF and PAF control loops are independent from each other since they

DC-link voltages, 2) reduced output current distortion and 3) reducing capacitor RMS current. The motor input currents have been regulated by controlling the output voltages of the inverters. The control strategies are implemented using OPAL-RT based real time prototyping tool. Operational time-step is kept constant at 25 µs. The parameters of the experiments are as follows: dc-link

Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. The circuit equations can be determined using Ohm’s Law, which gives the relationship between voltage and current in a resistor (V=IR), and Kirchhoff’s Current and Voltage Laws, which govern the currents entering and exiting a circuit node

Jean Louise Finch (Scout) is the daughter of Atticus Finch and the sister of Jem, she is also the main character and the narrator of the story, and she grows physically and morally throughout the book in positive and negative ways. There are multiple events in the story that changes her, they develop her morality too. For example her fear of the Radleys, Atticus’ parenting and how Jem and Dill’s friendship is larger than her with them. The world of ‘To Kill A Mockingbird’ was placed in the past,

3.0 Discussion on the important for nurses to be more visible   Barker emphasizes that to be appropriately valued in health care and by the public, it is critically important for nurses to be more visible "in every role and place of employment."Barker E,2001. 3.1 Power and empowerment Power and empowerment are connected to the image of nursing.Nurses typically do not like to talk about power,they find this to be philosophically different from their view of nursing.Power is about control to reach

by 40, you would find the full-time equivalence for that task and job type. I would have GGBP also identify any current part-time employees that could be transitioned into a full-time role. Then I would compare the needed manpower to what GGBP currently has to find where they will need to hire. Once hired, I would have the new full-time employees onboarded and trained while the current part-time employees continue to work. There will be an overlap of employees, but this will allow time for the new

The aim of this assignment is to describe an ethical dilemma from nursing practice and by using an ethical framework critically analyse the main issues arising from the problem. The essay will discuss the definition of ethics and it will briefly discuss the main theories of ethics. It will examine an ethical dilemma surrounding organ transplantation and it will analyse the conflicts by using the main principles of ethics. Finally, it will give recommendation in relation to ethics and its application

Appendix B and subpart P primarily consists of information regarding sloping and benching during the process of excavation and other aspects of construction. Sloping in construction is the incline of the surface of a soil area. Benching is when concrete is placed in a horizontal position at a slope fill to prevent sliding. The sloping and benching has to satisfy the OSHA requirements and regulations in order for the workers not to get injured or damage equipment. Another important aspect of construction

Maslow's Need Hierarchy Theory The first content theory is one of the most popular theories of motivation and was developed by Abraham Maslow. His theory focused on the psychological needs of employees and is based on two principles. He proposed that individuals are "wanting beings" and that they are motivated to satisfy certain types of needs. The second premise of Maslow's theory is that individual needs are arranged in a hierarchy of importance. Maslow's theory suggests that when a lower level
