Emerging technologies such as WiFi and WiMAX are profoundly changing the
landscape of wireless broadband. As we evolve into future generation wireless
networks, a primary challenge is the support of high data rate, integrated multi-
media type traffic over a unified platform. Due to its inherent advantages in
high-speed communication, orthogonal frequency division multiplexing (OFDM)
has become the modem of choice for a number of high profile wireless systems
(e.g., DVB-T, WiFi, WiMAX, Ultra-wideband).
This book is about the systematic application of the switching function technique for
theanalysisofpowerelectroniccircuits. Theswitchingfunctionmethodofanalysisis
basedonthederivationofthevoltage–currentexpressionsofaswitchedcircuitcover-
ing all modes into a single expression, a ‘unified expression’. A ‘unified expression’
istheresultofapplyingthesuperpositiontheoreminordertocombinetheexpressions
of all modes of the circuit into one expression with time varying parameters.
The main aim of this book is to present a unified, systematic description of
basic and advanced problems, methods and algorithms of the modern con-
trol theory considered as a foundation for the design of computer control
and management systems. The scope of the book differs considerably from
the topics of classical traditional control theory mainly oriented to the
needs of automatic control of technical devices and technological proc-
esses. Taking into account a variety of new applications, the book presents
a compact and uniform description containing traditional analysis and op-
timization problems for control systems as well as control problems with
non-probabilistic models of uncertainty, problems of learning, intelligent,
knowledge-based and operation systems – important for applications in the
control of manufacturing processes, in the project management and in the
control of computer systems.
The goal of this text is focus on a core subset of the natural language processing, unified
by the concepts of learning and search. A remarkable number of problems in natural
language processing can be solved by a compact set of methods:
實驗教學(xué)一直是工科教學(xué)中不可或缺的組成部分,對培養(yǎng)學(xué)生的動手能力,獨立思考能力,創(chuàng)新思維與發(fā)散思維具有重要的作用。針對目前電路教學(xué)實驗中電路仿真實驗與實物電路實驗各自獨立,無法統(tǒng)一問題,提出將仿真電路實驗與實物電路實驗有機的結(jié)合同步操作,并使用Web發(fā)布實現(xiàn)遠(yuǎn)程實驗操作。采用Multisim作為電路實驗仿真平臺,NI Eiviss II作為實物電路實驗硬件平臺,運用LabVIEW整合Multisim電路仿真實驗與實物電路實驗,實現(xiàn)仿真與實物實驗有機結(jié)合,兩種實驗可同步進(jìn)行。學(xué)生在仿真實驗中先可探索實驗,然后做實物實驗。同時運用LabVIEW開發(fā)出實驗過程人機交互操作接口界面,使用過程中效果良好。Experimental teaching has always been an indispensable part of engineering education.And it always plays an important role in cultivating students'practical ability,independent thinking ability,innovative thinking and divergent thinking.But simulation experiment and physical experiment cannot be unified in the circuit teaching experiment at present.In order to solve this problem,this paper proposes to combine organically the simulation circuit experiment with physical circuit experiment,and synchronously operate them.This paper uses the WEB publishing to achieve remote experimental operation.Multisim is used as the circuit simulation platform,and NI Eiviss II is used as the physical circuit hardware platform.Multisim circuit simulation experiment and physical circuit experiment are implemented by LabVIEW to realize the combination of simulation experiment and physical experiment.Students do explore experiments in simulation experiment firstly,and then do physical experiment.And this paper uses LabVIEW to develop the experimental man-machine interface.
