Control System Engineering by Norman S. Nise 6th Edition

Today i am going to upload a book, which i studied in 6th semester during my electrical engineering program, hope you will find best content in this book.
Main Chapters includes:

•  Introduction
• Modeling in the frequency domain
• Modeling in the time domain

• Steady-State errors
• Root locus techniques
• Design via root locus

• Appendix L: derivation of similarity transformations

• Appendix M: Root locus rules:derivations       

This book gives students to the theory and practice of control system engineering. Studey of control system engineering is good for students doing electrical, mechanical, biomedical, aerospace, or chemical engineering.
It is found in vast appliances from aircraft to robots and other controlling applications
This book is suitable for colleges and universities.Perquisites of this cource includes Mathematics,Physics,Ordinary differential equation. Important thing is to remember the Laplace transform, its application and linear algebra.
This book also includes some MATLAB commands to implements different function through commands and clocks too.
I prefer MATLAB 2012 for this book, because it includes various tools that are not present in previous versions.  
Best feature i say in this book is it communicates with the student, as there are many simple example which explains every topic in very easy manner, there are many case study about different application which are based on control system engineering like in the front page there is a Azimuth control system of Dish antenna, which is related in many examples through out this book that how it works, its different errors and their solution, discribed in good manner.
Thats why i said, this book is student friendly.
Other then case study, there are many review questions, numerical, and examples.  


Now im giving you a link of my mediafire account where i have  uploaded this book

Please let me know how is this book and important thing if you want more books let me know i will try to upload as soon as possible.
Best of Luck Engineers

Short review 

   

Screen
          its has 4.99 inch super AMOLED display with full HD 1920x1080 resolution and high pixel density of 441ppi, thats impressive, HTC has same size resolution but it is of smaller size.You can smoothly touch and drag your fingre.

Processor
              It has eight core processor, not eight core but two quad processor of about 1.6GHz, which means its the fastest ever processor i seen.

Battery
             It has 2600mA battery, which is much bigger then S3's battery, these type of batteries a vastly used in upcoming smart phones.

Camera
            It has 13 maga pixel camera with auto focus and backside-illuminated sensor for better low intensity light, there is also a flash that works at night.
It also has 2 maga pixel front camera for video calling, it also controls the brightness of phone.

Storage
            It can support upto 64 GB of memory card via microSD.

Release date
          Samsung has promised to have the phone at the end of april Exact date depends on country where you belong.

Conclusion
                   Early indication shows that is is going to be a superb handset. It face tough competition from its Android rivals and what ever Apple lans to relase next, interest and demand of this handset will remain high.

Generating Electricity

Sources of energy

1: Energy stored in water:-

           The potential energy of water at higher level is utilized for generation of electricity, water power is cheap where water is found in abundance, although capital cost of hydro power plant is higher than other power generation units, but their operating cost is very low.

2: Nuclear energy:-

          Controlled fission of heavily atoms such as U (235), Th (232) and artificial element like Pu(239) produce large amount of heat energy, which is then utilized on converting steam, which moves the turbine.

3: Wind energy

         Wind can also used as energy source for power generation where suitable velocity is available. It only generates a small amount of electricity, which can operate small pumps at tube wells. Wind power has served many countries as power source in early days hence called wind mill.

4: Solar energy

        Ray present in sun light are also used to convert water in steam, then this steam is used to move turbine to generate electricity.

Another important generation system of electricity is solar panel, which when place on sun light convert, it in to DC voltage, which then utilized to charge batteries or converted direct to AC voltage using inverter

5: Tidal energy

    Ocean waves and tides contain large amount of energy, Such tides can be rise or fall, during rise time water can be stored and during fall time this stored water is utilized in moving turbines to produce electricity.

But this method is only applicable near ocean,where tides are often.
