Wireless sensor networks by feng zhao and leonidal J Guibal

2011-02-28T20:04:00.000-08:00

Wireless sensor networks by feng zhao and leonidal J Guibal.
Inside, two eminent researchers review the diverse technologies and techniques that interact in today's wireless sensor networks. At every step, they are guided by the high-level information-processing tasks that determine how these networks are architected and administered. Zhao and Guibas begin with the canonical problem of localizing and tracking moving objects, then systematically examine the many fundamental sensor network issues that spring from it, including network discovery, service establishment, data routing and aggregation, query processing, programming models, and system organization. The understanding gained as a result--how different layers support the needs of different applications, and how a wireless sensor network should be built to optimize performance and economy--is sure to endure as individual component technologies come and go.

Hamdy Taha operation research 8th edition

2011-02-19T09:01:00.000-08:00

Hamdy Taha operation research Ebook 8th edition.

It starts with the basic introduction to "Linear Programming Problems" and then takes the subject to substantial depth in its first few chapters. Cocepts are explained in a very intuitive manner. Second subject it deals with is "The Transportation Problem" and it is just fabulous. You can solve any "Transportation Problem" if you have read this. Once again the concepts are so beautifully explained. Another chapter that I found interesting was CPM (Critical Path Method) and I liked it too. Positive point of the book is it explains the concepts to their full which is so important in understanding a complex subject like Operation Research. Its definitely worth buying if you are in this field. - Review from Amazon

Khazama AVR programmer v1.6.2

2011-02-18T04:30:00.000-08:00

Download here

These AVRs are generally classified into four main categories: tinyAVR , megaAVR , XMEGA , and Application specific AVR. Almost all AVR microcontrollers have internal EEPROM for semi-permanent data storage. Most of these chips have 2 buffers for programming which can be programmed using our various programmer models.

This simple AVR Programmer will allow you to painlessly transfer hex programs to most microcontrollers without sacrificing your budget and time. It is more reliable than most other simple AVR programmers available out there and can be built in very short amount of time.

The goals of this program is a nice small, fast, reliable and simple to use program. You can get and install it on windows based OS XP and Vista.

You can set your settings according to your project. this steps will execute after you push "Auto Program" button on the main window or press CTRL P shortcut.

Fuses and Lock window help you to set settings for AVR chips.All settings are documented and can select easily from combos or set directly from check boxes.

Optical Networks by kumar sivarajan, rajiv ramaswami and galen sasaki

2011-02-10T08:07:00.000-08:00

Kumar Sivarajan, Rajiv Ramaswami and Galen Sasaki, "Optical Networks: A Practical Perspective, 3 Edition"

Optical Networks continues to be the authoritative source for information on optical networking technologies and techniques. Componentry and transmission are discussed in detail with emphasis on practical networking issues that affect organizations as they evaluate, deploy, or develop optical networks. New updates in this rapidly changing technology are introduced. These updates include sections on pluggable optical transceivers, ROADM (reconfigurable optical add/drop multiplexer), and electronic dispersion compensation. Current standards updates such as G.709 OTN, as well as, those for GPON, EPON, and BPON are featured. Expanded discussions on multimode fiber with additional sections on photonic crystal and plastic fibers, as well as expanded coverage of Ethernet and Multiprotocol Label Switching (MPLS).
