Human Factors and Systems Interaction aims to address the main issues of concern
within systems interface with a particular emphasis on the system lifecycle
development and implementation of interfaces and the general implications of
virtual, augmented and mixed reality with respect to human and technology
interaction. Human Factors and Systems Interaction is, in the first instance, affected
by the forces shaping the nature offuture computing and systems development
n recent years, there have been many books published on power system optimization.
Most of these books do not cover applications of artifi cial intelligence based methods.
Moreover, with the recent increase of artifi cial intelligence applications in various fi elds,
it is becoming a new trend in solving optimization problems in engineering in general
due to its advantages of being simple and effi cient in tackling complex problems. For this
reason, the application of artifi cial intelligence in power systems has attracted the interest
of many researchers around the world during the last two decades. This book is a result
of our effort to provide information on the latest applications of artifi cial intelligence
to optimization problems in power systems before and after deregulation.

According to the demand, users can set the workingmodel of stepp ingmotor in real2time. This system can be widely used in stepp ing motor controlling. The p ractice showed that the performance of this system outdid the tradi tional stepp ing motor controller.KEY WORDS: Chip microcomputer; Stepp ingmotor; DCSSR; Real2time control
Abstract: This application note discusses the development and deployment of 3G cellular femtocell base stations. The technicalchallenges for last-mile residential connectivity and adding system capacity in dense urban environments are discussed, with 3Gfemtocell base stations as a cost-effective solution. Maxim's 3GPP TS25.104-compliant transceiver solution is presented along withcomplete radio reference designs such as RD2550. For more information on the RD2550, see reference design 5364, "FemtocellRadio Reference Designs Using the MAX2550–MAX2553 Transceivers."

UnZip is a small zipfile extract utility. It is written to be assmall portable as possible and is intended to be starting point for im-plementation of .ZIP files in non-IBM environments.Source code is provided in C and Turbo Pascal. If you port this programto a non-IBM system, I would appreciate a copy of the ported source andexe files.
The JDOM build system is based on Jakarta Ant, which is a Java building tool originally developed for the Jakarta Tomcat project but now used in many other Apache projects and extended by many developers.
This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain
