...Node Voltage Analysis (NVA) applicable to linear networks NVA gives you a process for obtaining n equations in n unknowns. The unknowns are the node voltages. Once you have the node voltages, you can find any voltage or current anywhere in the circuit. Process: (Note the key words to remember each step.) 1. Draw Draw the circuit diagram indicating all element and source values. 2. Label Label a reference node, usually ground or a node with the most branches. Then label a node voltage for all the other nodes in the circuit. You must recall the definition of a node voltage: It is the voltage of the node with respect to the reference node. It is not the same thing as the voltage across a branch. In general, the voltage across a branch between nodes 1 and 2will be the difference of the two node voltages on either side: v12 = v1 – v2 3. Dependant Write the controlling quantity of any dependant source in terms of node voltages. You will need to look for the controlling quantity in the circuit to do this. 4. Super Identify all the supernodes. Then write the voltage of the source inside the supernode in terms of the node voltages on either side. You must recall the definition of a supernode: It is any voltage source with the two nodes on either side of it considered as one big node. Note: Any equations that you get in this step will be part of the n equations. 5. Kirchoff Apply...

...Circuit Analysis using the Node and Mesh Methods We have seen that using Kirchhoff’s laws and Ohm’s law we can analyze any circuit to determine the operating conditions (the currents and voltages). The challenge of formal circuit analysis is to derive the smallest set of simultaneous equations that completely define the operating characteristics of a circuit. In this lecture we will develop two very powerful methods for analyzing any circuit: The node method and the mesh method. These methods are based on the systematic application of Kirchhoff’s laws. We will explain the steps required to obtain the solution by considering the circuit example shown on Figure 1. R1 + Vs R3 R2 R4 _ Figure 1. A typical resistive circuit. The Node Method. A voltage is always defined as the potential difference between two points. When we talk about the voltage at a certain point of a circuit we imply that the measurement is performed between that point and some other point in the circuit. In most cases that other point is referred to as ground. The node method or the node voltage method, is a very powerful approach for circuit analysis and it is based on the application of KCL, KVL and Ohm’s law. The procedure for analyzing a circuit with the node method is based on the following steps. 1. Clearly label all circuit parameters and distinguish the unknown parameters from the known. 2. Identify all nodes of the circuit. 3. Select a node as the reference node also called the ground and...

...Work is no longer a domestic relationship and we also saw that master as employer have great control their servant/employees in their work performance. Control becomes an important key to determine if a person is an employee as of today or to show if there is an employment relationship. There are differences between employees and independent contractors, an independent contractor is a person who agrees to deliver a certain outcome whereas an employee, who must obey instructions from his or her employer in the discharge of his duties, so independent contractor act independently from the principal that hires him.The independent contractor can delegate others to complete the job as the principal is not concerned with how the contractor does it, so long the outcome is achieved. Using control test from the common law, we can determine that Amanda is an employee of the company as the company control her working hours. We are concerned with the nature of the control and the degree of the control – Federal Commissioner of Taxation V J Walter Thompson (Aust) Pty Ltd (1994) Case. In Walter Thompson case, the company hired artists to perform radio plays for advertisements. The High court of Australia found that the producer controlled the actors during rehearsals and performance and held that there is an employment relationship here. Thus , we can use this case to prove that Amanda is an employee of the company. We can use the multi factor test to determine whether Amanda is the...

...When thinking critically about Benjamin Franklin’s view on the poor laws, it became apparent that his views were connected to the views of a conservative. Benjamin Franklin believed that “the best way of doing good to the poor is not making them easy in poverty, but leading or driving them out of it” (Williams, H.,1994). Analyzing Benjamin’s meaning behind this statement is thought provoking; from a conservative point of view this statement can be perceived as individuals needing to take care of them selfs without any help from social services or government agencies. Benjamin Franklin believed that all individuals should be solely responsible for themselves and their economic welfare even if they were to become disabled or elderly, the belief was that they should have prepared for the unknown (Williams, H., 1994). Franklin took the stance that the poor laws made individuals dependent on others to provide for them, which then would lead to increased poverty and reliance on government supports. Franklin argued that the less you provide for individuals forces the individual to do for themselves, promoting independence, self worth and riches. Although Franklin believed that getting assistance form private charities could be harmful; he also believed that if the government was able to delegate how the programs were managed then this would prove to be 1 more effective (Williams, H., g82). The view that the government would be able to police the programs to ensure that individuals...

...Commonalities and Successes Jacqueline Friederich BSHS/425 April 6, 2015 Joanie Blamer Commonalities and Successes Human service organizations are unique from organizations in the general business world. In this paper will explicate the essential focal point of all human service programs. It will as well identify the trends of human services, and identifying qualities of human service agency's associate with and how the office contributes to success. Central Focus of Human Service Programs Human service agencies work together, sharing the same goal in each program to enhance the client’s well-being (Lewis & Packard, 2012). In order to assist clients to improve their lives as human service professionals work together in different program settings. The common denominators are essential in the delivery of services. In order to enhance the client’s lives, each organization provides specific services but maintain the same goal. According to Harvey (1998), “having a very clear sense of purpose, direction, mission, or vision and a focus on its accomplishments is necessary to achieve excellence in Human Service Organization.” The human service mission is the needs of the client’s first and the commitment to improving the quality of life with the client and those in the community. Trends In Human Services Throughout the years, trends have changed the service delivery on the specific time. The different factors that change the service deliveries are political...

...of Hawaii’s most profound agencies known in the State of Hawaii that is correlated with human services is “Helping Hands Hawaii.” Although there are many agencies that have different approaches, human services rely on agencies that are most cost-efficient yet effective. Interoperability plays a major role in the future of human services. It is the “ability of two or more systems to exchange information and to use the information that has been exchanged” (Schoech, 2010). The three possible models for approaching interoperability in the human services are Loosely Linked Network Model, Network Model, and Top-Down Model. Human services emphasize in the importance of interoperability, as agencies collaborate with the same identified need to help others. Helping Hands Helping Hands Hawai’i manages numerous programs that benefit the people of Hawaii; this includes Behavioral Health Programs, Ready to Learn, Emergency Assistance Program and many more. Their mission is to support the community by improving the quality of people’s lives through the delivery of goods and services to those who are in need. For families and individuals, Helping Hands Hawaii is a new quality of life that overcomes the obstacles that block the way of meeting their full potential. This non-profit organization revenue from State agencies, grants from the local and national government and the Aloha United Ways. The annual donors that contribute to the agency helps the agency meet the growing needs of...

...Market and Nonmarket Environments Market environment includes those interactions (which involve voluntary economic transactions and the exchange of property) between firms, suppliers and customers that are governed by Markets and Contracts. Nonmarket environment is composed of the social, political and legal arrangements that structure interactions (between the firm and individuals, interest groups, govt. entities, and the public which are intermediated not by markets but by public and private institutions) outside of, but in conjunction with, markets and contracts. Public institutions differ from markets because of characteristics such as majority rule, due process, broad enfranchisement, collective action, and publicness. Activities in the non market environment are Voluntary when, firm cooperates with govt. officials or an environment group and are Involuntary in the case of, govt. regulation or a boycott of a firm’s product led by an activist group. Nonmarket issues high on firms agenda include : 1. Environmental Protection 2. Health & Safety 3. Regulation & Deregulation, 4. Intellectual Property Protection 5. Human Rights 6.

...expenses if Bills could find him another acting gig. The next night in a room at the Bay Hotel, Bills and Phillips were smoking marijuana; Bills’s lit marijuana cigarette caused a fire and burned down the hotel. Phillips was sued by Valley Television Productions for breach of contract and by the Bay Hotel for Bills’s negligence of starting the fire. Bills was also sued by the Valley Productions for breach of contract and filed for unemployment compensation after Phillips terminated their business relationship. RULES A fiduciary relationship results when one person (the principal) manifests her consent that another person (the agent) will act on her behalf and subject to her control, and the agent manifests his consent to so act. An agency by agreement relationship is based on an express or implied agreement that the agent will act for the principal. As per the Equal Dignity Rule, if a contract being executed by an agent on the principal’s behalf is written, most states require that the agent’s authority must also be evidenced by writing; otherwise, the contract executed by the agent is voidable at the principal’s option. However, a principal’s express or implied affirmation of a previously unauthorized contract made by, or other act of, a purported agent will result in ratification by the principal. Express or implied affirmation entails:...

...Medical Malpractice and Informed Consent In order to prove that Dr. Green was negligent in her treatment of Mr. Parker the plaintiff needed to prove that Dr. Green did not perform her duty, breached her duty, caused the injures, and that she suffered damaged. In this case, Dr. Green did not exercise reasonable care under the circumstances by not following the manufactures stated dosing instructions and prescribing the incorrect dose in both oral and written instructions. Dr. Green violated her breach of duty by failing to meet the applicable standard of care. It would be hard to argue that others physicians would have prescribed the incorrect dose in their standard treatment of care. It is my opinion that plaintiff would succeed in proving that Dr. Green did not perform her duty and breached her duty. While the statement of facts presented does not state the amount that is needed to overdose on pentamite or what effects of an incorrect dosage will have on an individual taking pentamite, the plaintiff could argue that taking the prescribed dosage of 10 times the stated dose by the manufacturer for two weeks caused the heart attack that ended Mr. Parker’s life. Dr. Green could argue that the dizzy spells were a sign of a medical condition that no matter what treatment she gave, the heart attack that ended Mr. Parker’s life could have happened and she did not cause it. In order to estimate the success of this claim I would need more information about pentamite and need...

...Most government agencies are wasteful. But NASA is a vital agency to this nation because it does push our country to develop technology. A lot of good science comes out of NASA. The sad thing is that NASA is run by politicians who cannot or do not understand the agencies mission or its value to the economy. NASA's budget, although large compared to the average income, is very small compared to the national budget. It is one of the few agencies of the US government that actually put more money into the economy that it takes out. I think it is a worthwhile endeavor to explore the things around us. One positive thing about human curiosity is the survival value it brings. According to News.com “A new private space industry could create ten thousand new jobs across the country in five years.” NASA and the aerospace industry provide thousands of jobs across the country they do more than just space exploration they also monitor our environment from space, procure satellites for other agencies and develop the next generation of aircraft technologies. I think President Obama’s reasons are not directly related to the current state of the economy. He has made clear that his priorities are the re-distribution of wealth away from those that are producing it to supply the needs of those that are not producing it. If the economy was booming, President Obama would not reinstate the programs he has canceled. But he will earn the political favor of those that he temporarily pretends to help...
