Parallel processing in computer aided control system design

Chipperfield, Andrew John January 1995 (has links)
The available sources have, to some extent, determined the form of this thesis, which was undertaken in the hope that a more detailed study of the relations between London and the Crown during the years 1 1400_1 1150 would place in perspective the crises with which it begins and ends. The most important source of material for this study has been the Journals of the Court of Aldermen and Common Council which survive from 1416 (the years 1429- 1436 are missing). Historians with the help of a nineteenth century index have quarried in these Journals, but they have never been read through systematically. Journals nos. 3 and 6, having been wrongly bound up, could not be used until, their pages bad been sorted into the correct order from the internal evidence of their contents. The scribes who compiled the Journals were both careless and cautious which increases the difficulty in interpreting their crabbed notes. From studying the Journals dominant themes emerged which were then followed up at the Public Record Office and elsewhere. The conclusions from this study fall into three main categories. The Journals provided a great deal of material from which it was possible to draw a much more detailed picture of the machinery and business of the government of medieval London. T1'e Aldermen and civic officials emerge as conservative, but conscientious, men who might press hardly upon minority interests, but had constantly before their eyes the needs of the City as a whole. Secondly it has been possible to tidy up the chronology of the crises themselves. At such times as Bolingbroke' s usurpation and Cade' a revolt the civic scribes were least active and most cautious. But it seems clear that the London support for both these men has been exaggerated and that the fundamental conservatism of the City governors was not easily rocked, whether by royal scions or Kentish peasants. But this study has proved most useful where the more mundane contact between the Crown and the citizens could be examined, In this way it has been possible to place the financial relations between the King and the City in perspective, and to realize that the King did not come as a beggar to the Londoners, since he had at his disposal all the chartered freedoms and privileges which were essential to the communal and economic life of the City. London, in spite of its great prestige and financial importance, still operated in the fifteenth century within a framework of royal privilege. While the memory of Richard II's action in 1392 was still green the Londoners were in no position to demand redress of grievances before supply. In understanding the delicate balance of the relationship between the Crown and the Londoners it is easier to understand the survival of the Lancastrian dynasty.

Process and Analysis of Voice Signal by MATLAB

Wu, Nan, Wang, Bofei January 2014 (has links)
Deliver message by voice is the most important, effective and common method of exchange information for mankind. Language is human specific features and human voice is commonly used tool which is also the important way to pass information to each other. The voice has large information capacity. So we can use modern method to study voice processing technology, so that people can easily transmit, store, access and apply the voice. In this thesis, we designed a collection system that can collect voice and use different filters to filter the noise. After filtering the noise, the voice will be more quality in mobile communication, radio, TV and so on. In this thesis we use Microsoft recorder to collect a voice, and then analyze its time-domain, the frequency spectrum and the characteristics of the voice signal. We use MATLAB‟s function to remove the noise which has been added to the voice, further use bilinear transformation method to design a filter which is based on Butterworth simulation and window function and then filter the voice signal which has been added noise. After that we compare the time-domain and frequency-domain of the original voice and noised voice, then playback the noised voice and de-noising voice and then compare the application of signal processing in FIR filter and IIR filter, especially in the perspectives of the signal filtering de-noising characteristics and applications. According to the comparison, we can determine which filter is the best.

MATLAB*G: A Grid-Based Parallel MATLAB

Chen, Ying, Tan, Suan Fong 01 1900 (has links)
This paper describes the design and implementation of MATLAB*G, a parallel MATLAB on the ALiCE Grid. ALiCE (Adaptive and scaLable internet-based Computing Engine), developed at NUS, is a lightweight grid-computing middleware. Grid applications in ALiCE are written in Java and use the distributed shared memory programming model. Utilizing existing MATLAB functions, MATLAB*G provides distributed matrix computation to the user through a set of simple commands. Currently two forms of parallelism for distributed matrix computation are implemented: task parallelism and job parallelism. Experiments are carried out to investigate the performance of MATLAB*G on each type of parallelism. Results indicate that for large matrix sizes MATLAB*G can be a faster alternative to sequential MATLAB. / Singapore-MIT Alliance (SMA)

Solving Multiple Classes of Problems in Parallel with MATLAB*P

Choy, Ron, Edelman, Alan 01 1900 (has links)
MATLAB [7] is one of the most widely used mathematical computing environments in technical computing. It is an interactive environment that provides high performance computational routines and an easy-to-use, C-like scripting language. Mathworks, the company that develops MATLAB, currently does not provide a version of MATLAB that can utilize parallel computing [9]. This has led to academic and commercial efforts outside Mathworks to build a parallel MATLAB, using a variety of approaches. MATLAB*P is a parallel MATLAB that focus on enhancing productivity by providing an easy to use parallel computing tool. Using syntaxes identical to regular MATLAB, it can be used to solve large scale algebraic problems as well as multiple small problems in parallel. This paper describes how the innovative combination of ’*p mode’ and ’MultiMATLAB/MultiOctave mode’ in MATLAB*P can be used to solve a large range of real world problems. / Singapore-MIT Alliance (SMA)

Mäki, Jonas January 2011 (has links)
This report describes how to process audio signals in real time with a digital signalprocessor. The digital signal processor used in the thesis and described in the reportare the Blackfin processor ADSP-BF537 from Analog Devices. In the body of this report there is theory of the processor characteristics and thevarious programming languages used. All experiments that were made on theprocessor are described, these descriptions also help in understanding the annexeswhere the experiments will be presented. The body of this report also describes theprogram used to do experiments. Testing the CPU limit was done and the results arepresented to get a good view of what it can handle. The tests were ruling the use forwhich the processor will be used in the course of signal processing. A Introductionlaboration going through settings on the processor and a simple signal processingapplications is described. The guide is also attached to the end of the report (seeAnnex 1 for Introduktionslaboration i LabVIEW, page 20). Implementation of the labare done with both LabVIEW and Matlab on the processor. This was tested to seewhich program was most appropriate to use. The pros and cons of both programsare described. The final section of the report mentioned observations of the problems encounteredand suggestions for how to proceed in the future. Options other than the processorused in this thesis are mentioned and described. References to information sourceson the Internet were information was gathered and used to program the processor isindicated. Finally the report ends with appendices, where each step is described in theexperiments that was implemented on the processor. Even more specific informationabout how everything will be implemented in the programs are described and theadvantages and disadvantages they have.
