The concept of this book is that of a personal tool, which compacts 20 percent of the data is needed 80 percent of the time by electrical design professionals in the preliminary design of buildings of all types and sizes. This tool is meant to always be at one's fingertips ( open on a drawing board, desk, or computer table; carried in a briefcase; or kept in one's pocket).
The book addresses practical engineering issues that antenna professionals have to deal with. It explains the immediate demands for existing systems; discusses the antenna technology for the latest and emerging applications, and gives comprehensive coverage of hot topics in the wireless industry. Issues including design considerations, engineering design, measurement setup and methodology, and practical applications are all covered in depth.
Chapter 1 is a general introduction that introduces professional software engineering and defines some software engineering concepts. This chapter also introduces system for managing records of patients undergoing treatment for mental health problems, a control system for a portable insulin pump and a wilderness weather system.
Symbian OS C++ for Mobile Phones Volume 3 draws on the experience of Symbian’s own engineers to provide a thorough grounding in writing C++ applications for mobile phones that use Symbian OS version 9.0 and beyond. It won’t teach youeverything you need to know about developing Symbian OS applications – no single book could do that. However, it will take you a long way along the road to being an effective Symbian
OS developer, and give you a deep understanding of the fundamental principles upon which Symbian OS is based...

PLANNING CAPITAL EXPENDITURE.
Steven P. Feinstein.
A beer company is considering building a new brewery. An airline is deciding whether to add f lights to its schedule. An engineer at a high-tech company has designed a new microchip and hopes to encourage the company to manufacture and sell it. A small college contemplates buying a new photocopy machine. A nonprofit museum is toying with the idea of installing an education center for children. Newlyweds dream of buying a house. A retailer considers building a Web site and selling on the Internet.
Manufacturers base the performance of electronic devices on a perfect battery, a condition that only exists when the battery is new. By reading Batteries in a Portable World, you will acquire a better understanding of the strengths and limitations of the battery, learn about different battery types and discover what conditions are best for a battery.
The book is easy and entertaining to read and makes minimal use of technical jargon.
The confluence of market demand for greatly improved
compact power sources for portable electronics with the rapidly
expanding capability of micromachining technology has made
feasible the development of gas turbines in the millimeter-size
range. With airfoil spans measured in 100’s of microns rather
than meters, these “microengines” have about 1 millionth the
air flow of large gas turbines and thus should produce about 1
millionth the power, 10-100 W.
The purpose of these recommended guidelines is to promote safety in the use of power boilers. The term “power boiler” in this Section includes stationary, portable, and traction type boilers, but does not include locomotive and high temperature water boilers, nuclear power plant boilers.
In recent years, the ICT market has quickly moved toward the integration of a large
variety of functions into a single portable electronic equipment. The boundaries
among different devices like music players, digital cameras or mobile phones are
going to vanish. In this trend, one of the key factors is played by data storage, since all
these devices require a large amount of memory to store either audio or visual data.
Also, the energy consumption needs to be reduced to further extend battery duration
and the functionality of the devices....
Electronic copies of this and other U.S. Army Corps of Engineers (USACE) publications are available on the Internet at http://www.usace.army.mil/inet/usace-docs/. This site is the only repository for all official USACE engineer regulations, circulars, manuals, and other documents originating from HQUSACE. Publications are provided in portable document format (PDF).
ating systems written in C, a high-level programming language, and its natural portability and low price made it a popular choice among universities. Initially, two main dialects of Unix existed: one produced by AT&T known as System V, and one developed at UC Berkeley and known as BSD. In recent years, many other dialects have been created, including the highly popular Linux operating system and the new Mac OS X (a derivative of BSD).
In computer programming, readability refers to the ease with which a human reader can comprehend the purpose, control flow, and operation of source code. It affects the aspects of quality above, including portability, usability and most importantly maintainability.
Readability is important because programmers spend the majority of their time reading, trying to understand and modifying existing source code, rather than writing new source code. Unreadable code often leads to bugs, inefficiencies, and duplicated code.
Photovoltaic engineering is a multidisciplinary speciality deeply rooted in
physics for solar cell theory and technology, and heavily relying on electrical and electpolrlli;c
engineering for system design and analysis.
The conception, design and analysis of photovoltaic systems are important tasks oh
requiring the help of computers to perform fast and accurate computations or simuhfim.

Broadband Wireless Mobile (3G and 4G) will be the next key developments in wireless communications. Immense interest has been fuelled by large demand for high frequency utilisation as well as a large number of users requiring simultaneous multidimensional high data rate access for the applications of wireless mobile internet and e-commerce. Broadband wireless mobile extends the corporate LAN to common areas such as meeting rooms and enables in-building public wireless hotspots such as airport lounges to provide wireless portable computer connectivity...
Robot RE là gọi tắt tên một nhóm robot phục vụ kỹ thuật tái hiện
ngược (Reverse Engineering). Nhận xét rằng, cơ cấu của các máy đo toạ độ
CMM (Coordinate Measuring Machines) rất quen biết trong công nghiệp,
cũng như cơ cấu của các thiết bị tay đo hoặc CMM cầm tay (Portable
coordinate measuring machine - PCMM) đều có cấu trúc động học như các
loại cơ cấu robot.
The book consists of 21 chapters which present interesting applications implemented using the LabVIEW environment, belonging to several distinct fields such as engineering, fault diagnosis, medicine, remote access laboratory, internet communications, chemistry, physics, etc. The virtual instruments designed and implemented in LabVIEW provide the advantages of being more intuitive, of reducing the implementation time and of being portable.
Making devices small has long had engineering, scientific, and aesthetic motivations.
For example, John Harrison’s quest  to make a small (e.g., hand-sized)
chronometer in the 1700s for nautical navigation was motivated by the desire to
have an accurate time-keeping instrument that was insensitive to temperature,
humidity, and motion. A small chronometer could meet these objectives and allow
for multiple instruments on a ship for redundancy and error averaging. A number
of technological firsts came from this work, such as the development of the roller
Wi-Fi can further enhance your organization's productivity and savings by increasing portability and eliminating charges for PBX maintenance and for wire-line and cellular phone service. However, concerns about the QoS of Wi-Fi and VoIP prevent many organizations from realizing the full savings and productivity improvements that Wi-Fi can deliver. This guide to deploying Wi-Fi telephony helps you overcome these concerns by showing in detail how to engineer each component of Wi-Fi for reliable, high- quality voice transmission.
