The subject of this monograph is the fluid dynamics of liquid turbomachines, particularly pumps. Rather than attempt a general treatise on turbomachines, we shall focus attention on those special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to these special problems, and cause a significantly different set of concerns than would occur in, say, a gas turbine. These are the potential for cavitation and the high density of liquids that enhances the possibility of damaging unsteady flows and forces.

Stepper Motor Control with Microcontroller
Tuesday, August 25th, 2009This note provides basic implementation details and procedural information to design and assemble a stepper motor system. The controller discussed here is the MC68HC11E9, an 8-bit Motorola microcontroller (MCU). There are many embedded control applications supported by the M68HC11 Family.
The note consists of a general description and gives highlights of implementing a basic stepper motor system application. A step-by-step hardware assembly section is included to promote ease of construction should one desire to build a similar system.

Understanding Electronics Components
Thursday, August 20th, 2009This book is meant for those people who want to create electronic devices with their own hands. All components are illustrated and the circuit-symbol is explained in detail. Both simple and complex examples are provided for the beginners. These include resistors, capacitors, transformers, transistors, integrated circuits, etc and each has its own symbol to represent it in an electrical or electronic diagram – called a circuit diagram. In order to understand how a certain device functions, it is necessary to know each symbol and the characteristics of the component. These are the things we will be covering in this book

Introduction To Machine Learning
Tuesday, August 18th, 2009This book surveys many of the important topics in machine learning circa 1996. The intention was to pursue a middle ground between theory and practice. This book concentrates on the important ideas in machine learning — it is neither a handbook of practice nor a compendium of theoretical proofs. The goal was to give the reader sufficient preparation to make the extensive literature on machine learning accessible.
Introduction to PLC controllers
Tuesday, August 18th, 2009PLC are industrial microcontroller systems where hardware and software are specifically adapted to industrial environment. The key to their success is the fact that you don’t have to learn a new programming language to program them. How do they work exactly? How to connect a simple sensor? How to program in ladder diagram? In this book you will find the answers to these questions and more.
