51281. Distributed generation effects on voltage profile of distribution grid with SVC and smart inverter
- Creator:
- Tayyab, Muhammad Arslan
- Description:
- A properly planned interconnection of Distributed Generation (DG) to the grid can help minimize system loses, and defers system upgrades. Higher penetration level of DG has been known to negatively affect the steady state voltage profile, intermittent voltage fluctuations, and possible line overloads. Static VAr Compensators (SVC) and Smart Inverters (SI) are considered as viable equipment for mitigating the voltage effects caused by DG. This project aims to investigate and verify the overvoltage and overloading issues caused by DG at high penetration levels. A real distribution feeder from a local utility was selected using cluster analysis for simulations. A commercial software was used for all simulations. DG at various penetration levels was interconnected at 4 different locations on the feeder. Summer Peak (SP), Partial Peak (PP) and Winter Peak (WP) loading conditions have been studied. Solar Photo-Voltaic (PV) is used as a DG for simulations. SVC and SI were proposed as possible solutions and their mitigating effects have been reported. Acceptable penetration levels of DG have been proposed depending on location of DG and associated voltage or overloading issues. Overloading of cables and lines is indicated in terms of percentages. Two special cases, one involving simultaneous high and low voltage conditions and the other related to high voltages at multiple locations, have also been studied. Proposed solutions for both cases have been reported.

- Description:
- The project addressed the problem of instructors struggling to teach and discuss controversial issues in their classrooms. Through the literature review, a variety of practices and strategies presented a means for productively exploring volatile and passionately felt topics in the classroom without endangering or offending other students. Overall, the literature regarding the instruction of controversial issues is very limited, but from the available resources that exist, the handbook is a compilation of mini-lessons and suggested resources. The mini-lessons in the handbook comprise of literature based teaching methods, other handbooks, and literature suggestions by social studies researchers. The focus of the research regarding teaching controversial issues was based on the sever need for the discussion of controversial issues in the lower grades like middle and high school. In addition to providing resources, the literature consistently revealed many of the shortcomings of the topic.

- Description:
- The purpose of this project was to create a PowerPoint presentation and website link that would benefit educators, parents, and transition-age youth with disabilities. The problem this author identified is that transition-age youth with disabilities not only neglect planning for or thinking about post-secondary education or employment while in high school, but they are also unaware of and do not have access to the various organizations, services, and options they have at their disposal. The research sources for the development of this project included peer reviewed journals, books, information from relevant websites, personal communication, and Masters Projects from California State University, Sacramento (CSUS) Vocational Rehabilitation graduate students. A PowerPoint presentation and a website link on the Placer County Network of Care website was developed to help better prepare transition-age youth with disabilities for their lives after high school.

- Description:
- The objective of the project is to design a learning application for android-based devices that will track the user’s behavior pattern and allow the user to manage his device smartly. There are a few existing apps that are already exhibiting this behavior for example App Usage Tracker . However, Smart app does provide more knowledgeable actions compared to others (for example: comparison between user’s top favorites and user’s calculated favorites, easy access to the favorite apps by creating shortcuts on the home screen etc.). App Usage tracker application is also capable of learning the user’s mobile behavioral patterns. The behavioral patterns captured would include number of things that would help the mobile users to combine statistics and provide insights into mobile device usage. For instance, Smart will tell which applications the user uses frequently on a certain period like daily, weekly and monthly by which the user will come to know which apps he/she uses regularly. That would be the user’s favorite app-“the app used most frequently”. There would also be comparison between the user’s top rated apps (wherein user gives initial rating to the apps according to his choice) v/s user’s calculated favorite rating (which would be coming from the learning done on the user’s behavior patterns). Along with this learned data of user’s behavior patterns, the application also provides an insight into the average power consumption for the apps. This app is also intended to use the data gathered from learning a user's patterns to convert them into some knowledgeable actions that would enable more effective device use. For instance, creating a shortcut of the learned favorite apps to the home screen. This list will be refreshed every time the application is run. In this way, the old favorite list would be refreshed automatically. The user will also be notified for the maximum battery using app during the course of his usage based on a certain set threshold.

- Description:
- When offenders commit crimes, the opportunity for both victims and offenders to confront each other about the harm that has been inflicted is usually nonexistent. Restorative justice program provides the opportunity for victims, their families, offenders, community members, and professionals to collaboratively address the impact of the crime on all individuals and the community at large, and develop an organized agreement to repair the harm. The purpose of this research was to gain a better understanding of juvenile justice professionals’ perspectives toward restorative justice programs for purposes of expanding awareness and implementation of such programs. This study is a secondary data analysis where exploratory, quantitative data administered to various juvenile justice professionals was analyzed. The data was analyzed using the Kruskal-Wallis test and examining frequency distributions. The results from the study found that juvenile justice professionals support the efficiency of restorative justice programs and policies for young offenders.

- Description:
- This study focuses upon the growing placement of foster care children in kinship placements. With an emphasis on the family preservation model and the growth of kinship care foster placements by Child Protective Services (CPS), it is necessary to analyze the accessible and beneficial programs available to these families. Policies, agencies and community programs have adapted to the growth of kinship families; however, the effectiveness and accessibility of these programs to kinship families has yet to be analyzed. The research for this project examines past and present policies affecting kinship foster care families in the United States, specifically in California. The project centralizes on Sacramento County. The research contained in this project is based upon a qualitative, descriptive approach. Sacramento County CPS social workers providing direct case management were asked to participate in the research. The majority of participants have approximately one-quarter of their caseload occupied by kinship foster care placements. Based on the experiences of these social workers, it was identified that the main resource needed by kinship foster caregivers is financial support. Many of the barriers identified by these social workers, and explained more thoroughly over the course of this project, were linked to the lack of monetary aid. A surprising outcome of the study is the grave need for social and familial support services to these families. While the researchers’ general hypothesis of a need for additional resources was sustained, the multitude of available resources to these families in the Sacramento County region disproved the academic research stating otherwise.

- The Home Area Market is now emerging within the smart grid sector to serve home with digital application solutions and energy management. Home Area Network has high implications for homeowners, utilities and smart grid vendors, as utilities are seeking means to implement demand side management programs. The installed base of smart home networks globally is expected to increase from 1.5 million homes in 2009 to 14.7 million in 2014. [1] The next big thing after smart meters is sending messages from those meters to in-home displays, smart thermostats, and smart appliances. These messages contain the usage, pricing, and control information that enable consumers to capture the desired smart meter and Smart Grid benefits of demand response, energy efficiency, renewables integration, distributed generation, and electric vehicle charging. The main goal of this project is to study the behavior of the HAN using Direct Propagation Model and the Path loss model. The Path loss model used is the project is Gauss Siedel Model. The path loss model was used to see the difference in attenuation when there is free space and when the obstacles/materials from boundary walls are introduced. Various simulation studies were performed by varying the transmission parameters, such as loss coefficients of materials, and graphs were generated to compare results. The results give us better understanding of the how the HAN networks work along with measuring the loss of signal during propagation from transmitter to receiver.

- This Project was prepared to recount and analyze my personal experience in acquiring, rehabilitating, leasing and disposing of a small income producing asset. The asset is a Victorian Italianate residential duplex, constructed in 1880 and located in midtown Sacramento. The Project explores the challenges facing undercapitalized and inexperienced investors and offers my strategy in leveraging a small savings to overcome these barriers. My recommendation will be determined by achieving two criteria 1) the project must return an after-tax Internal Rate of Return (IRR) of 20% and a positive after-tax Net Present Value (NPV); and 2) the potential for replication by similarly undercapitalized and inexperienced investors in a normal market. SOURCES OF DATA: Data were collected using a myriad of sources, including online research, correspondence with industry professionals, various publications and actual financial figures obtained through ownership records. CONCLUSIONS REACHED: The calculated after-tax IRR of the project is 208.15% and an after-tax NPV (20% required rate of return) of $109,155. Despite these large financial measurements of return, the project’s success was found to be heavily influenced by the favorable real estate market conditions of 2012-2014. As a result, the project is not considered to be replicable in a normal market, and therefore not recommended to all investors.

51289. Echo-Incarnate
- Creator:
- Burrell, Adam Shea
- Description:
- In this manuscript, I attempt to articulate and present a fully formed aesthetic through poetry and brief prose pieces. Problems I address include spirituality in art, technology, language play, composition by field, and the mystery of pronouns. I attempt to foreground the materiality of language in “Call,” the first section. I was influenced by the writings of Robert Creeley and e.e. cummings, among others, in the composition of “Call.” The second section, “How,” is titled after the Hebrew name for the Biblical book of Lamentations, and alludes to “Howl” by Allen Ginsberg. It is intended as a nexus of contemporary life in Sacramento, Allen Ginsberg’s “Howl,” and Lamentations. I conclude the manuscript with a somewhat tongue-in-cheek response to T.S. Eliot’s Tradition and the Individual Talent.

- Description:
- According to the modern portfolio theory, investors should not limit themselves to the expected risk and return of one particular stock. Investors should reduce risks through diversification because the risk in a portfolio of diverse stocks will be less than the risk of any one of the stocks. The key is diversification. Diversification is not as simple at owning ten different stocks, but to comprise assets that are relatively unrelated in order to mitigate risks. This is important when one sector performs poorly, while other sectors are performs well. In classrooms, finance students learn the principles of investment analysis and investment courses cover topics of asset management utilizing Markowitz portfolio theory, Capital Market theory, and other investment strategies. However, most of these finance courses do not provide the skills you need to build these financial models for private or professional use. There are four basic steps involved to construct optimal portfolios that offer the maximum possible expected return for a given level of risk; security valuation, performance measurement, asset allocation, and portfolio optimization. By using Excel, Visual Basics for Applications (VBA), and data from Yahoo Finance, you will able to analyze and build an investment portfolio. This document will be helpful for those who want to expand their knowledge in finance and investments analysis by implementing these theories in Microsoft Excel. It will take time to initially set-up the spreadsheets with the desired data and entering the necessary formulas and VBA code, but once done correctly, comparing different equity securities will be relatively simple. Excel is a superb data analysis tool. Also, Yahoo Finance is a reliable source of free financial data information. It supports bulk data downloads which simplifies the task of downloading the historical financial data from finance.yahoo.com to Excel. This document is a hands-on approach to apply complex financial theories using Excel and VBA as a medium. The following chapters are written to be purposefully easy to understand to be suitable for anyone with a basic understanding of finance and Excel. The easy-to-follow guide will effectively walk you through the process of completing various Excel spreadsheets to develop a graphical depiction of the trade-off between risk and return for an efficient portfolio.
