The term ìspreadsheetî covers a wide variety of elements useful for quantitative
analysis of all kinds. Essentially, a spreadsheet is a simple tool consisting of a
matrix of cells that can store numbers, text, or formulas. The spreadsheetís power
comes from its ability to recalculate results as you change the contents of other
cells. No longer does the user need to do these calculations by hand or on a
Power flow solutions are needed in both for planning and operation studies.
Power flow studies for three phases balanced power system can be carried out using
very efficient methods. Power flow analysis for certain type of power system
network can be carried on by using several software that already been develop
without manual calculation on this time. One of the software is MATLAB with its
toolbox: Power System Analysis Toolbox. This software also uses numerical
methods to do power flow analysis like Newton-Raphson and its modified form, Fast
Thermal power plants are one of the most important process industries for engineering professionals. Over the past decades, the power sector is facing a number of critical issues; however, the most fundamental challenge is meeting the growing power demand in sustainable and efficient ways. Practicing power plant engineers not only look after operation and maintenance of the plant, but, also look after range of activities including research and development, starting from power generation to environmental aspects of power plants.
PSAT is a Matlab toolbox for static and dynamic analysis and control of electric power systems. The PSAT project began in September 2001, while I was a Ph.D. candidate at the Universit´ degli Studi di Genova, Italy. The ﬁrst public a version date back to November 2002, when I was a Visiting Scholar at the University of Waterloo, Canada. I am currently maintaining PSAT in the spare time, while I am working as associate professor at the Universidad de Castilla-La Mancha, Ciudad Real, Spain. PSAT is provided free of charge, in the hope it can be useful and other people...
The objective of this book is to present methods of power system analysis and
design, particularly with the aid of a personal computer, in su‰cient depth
to give the student the basic theory at the undergraduate level. The approach
is designed to develop students’ thinking processes, enabling them to reach a
sound understanding of a broad range of topics related to power system
engineering, while motivating their interest in the electrical power industry.
An updated approach to reference frame analysis of electric machines and drive systems
Since the first edition of Analysis of Electric Machinery was published, the reference frame theory that was detailed in the book has become the universally accepted approach for the analysis of both electric machines and electric drive systems. Now in its second edition, Analysis of Electric Machinery and Drive Systems presents, in one resource, the application of this theory to the analysis, simulation, and design of the complete drive system including the machine, converter, and control....
If you need to create and interpret statistics in business or classroom settings, this easy-to-use guide is just what you need. It shows you how to use Excel's powerful tools for statistical analysis, even if you've never taken a course in statistics. Learn the meaning of terms like mean and median, margin of error, standard deviation, and permutations, and discover how to interpret the statistics of everyday life. You'll learn to use Excel formulas, charts, PivotTables, and other tools to make sense of everything from sports stats to medical correlations....
In writing this book the author has been primarily concerned with the presentation
of the basic essentials of power-system operation and analysis to students in the
final year of first degree courses at universities and colleges of technology. The
emphasis is on the consideration of the system as a whole rather than on the engineering
details of its constituents, and the treatment presented is aimed at practical
conditions and situations rather than theoretical nicety.

With technology advancements in semiconductor devices such as insulated gate
bipolar transistors (IGBTs) and gate commutated thyristors (GCTs), modern highpower
medium voltage (MV) drives are increasingly used in petrochemical, mining,
steel and metals, transportation and other industries to conserve electric energy,
increase productivity and improve product quality.
Although research and development of the medium voltage (2.3 KV to 13.8 KV)
drive in the 1-MW to 100-MW range are continuously growing, books dedicated to
this technology seem unavailable.
Spreadsheets provide one of the most easily learned routes to scientific computing. This book uses Excel®, the most powerful spreadsheet available, to explore and solve problems in general and chemical data analysis. It follows the usual sequence of college textbooks in analytical chemistry: statistics, chemical equilibria, pH calculations, titrations, and instrumental methods such as chromatography, spectrometry, and
Thermal power plants are one of the most important process industries for engineering professionals. Over the past few decades, the power sector has been facing a number of critical issues. However, the most fundamental challenge is meeting the growing power demand in sustainable and efficient ways.
This book covers various topics, from thermal-hydraulic analysis to the safety analysis of nuclear power plant. It does not focus only on current power plant issues. Instead, it aims to address the challenging ideas that can be implemented in and used for the development of future nuclear power plants. This book will take the readers into the world of innovative research and development of future plants. Find your interests inside this book!Steam Generator
Lysergic acid diethylamide (LSD, lysergide) is known as one of the most powerful hallucinogenic drugs of abuse. LSD was explosively abused in U.S.A. in the latter half of the 1960s. In Japan, the amount of seizure of LSD is much smaller than that of methamphetamine. However, in recent years, it has been increasing markedly; 3,500 tablets of LSD were seized in 1996, while 53,043 tablets in 2000 (about 15-fold increase), arousing a serious concern about the phenomenon. LSD is a compound chemically modified from ergot alkaloid produced by a bacterium Claviceps purpurea.
Organophosphorus pesticides (organophosphate pesticides) are being most widely used as insecticides, and thus cause poisoning cases frequently. The organophosphorus pesticides at the early stage, such as parathion and TEPP, had powerful insecticidal effects and high toxicity for both humans and beasts, and caused poisoning accidents during spraying. Although many less toxic organophosphorus pesticides were then developed, the resistance to the pesticides was acquired by insects during their repeated use, resulting in less effectiveness of the pesticides.
The serious challenge facing the world today, in obtaining enough energy for growing population and in controlling the carbon emission caused by fossil fuel use, calls for nuclear energy as an alternative power source. This book presents research work and technical experience from several power plants and research institutions around the world from practical prospective.
