The inside-outside algorithm : Grammatical inference applied to stochastic context-free grammers by L Dodd( Book )

4 editions published between 1988 and 1989 in English and held by 7 WorldCat member libraries worldwide

This paper describes an application of the Inside-Outside algorithm to learning rules for the spelling of English words. The initial experiments examine the effect of using prior knowledge and further experiments compare stochastic regular grammars with stochastic context-free grammars. The problems of using the Inside-Outside algorithm are discussed and an implementation on an Array Processor is described. Keywords: Great Britain. (fr)
ADA on multiple processors by John McDermid( Book )

3 editions published in 1982 in English and held by 6 WorldCat member libraries worldwide

This paper considers a number of possible ways of implementing the Ada rendezvous in a computer system comprising a number of processors. It shows that, in principle, a two phase protocol requiring four messages to be passed is necessary to implement the rendezvous correctly when timed calls are used. However in many cases a simpler, one phase, protocol requiring only two messages per rendezvous can be used. A comparison is made between the rendezvous and message based communication for situations where one to many, rather than one to one, communication is required. The rendezvous is shown to be very inefficient for implementing one to many communciation. Finally some of the problems of loading and running Ada programs are briefly considered. (Author)

Monte-Carlo simulations of gas discharge systems with some application to SF6 by P. K Milsom( Book )

2 editions published in 1990 in English and held by 6 WorldCat member libraries worldwide

The Monte Carlo method is used to consider the behaviour of an electron swarm released into a Sulphur HexaFluoride gas discharge. The mean energy of the swarm is monitored as a function of time and when the steady state is reached the energy and velocity distributions are calculated. The growth in electron number is also monitored and this is used to determine the stable working field in the gas. The results confirm that the two term Boltzmann equation is adequate for calculating electron energy distribution functions
Properties of density tapered arrays by G. J Ball( Book )

3 editions published in 1988 in English and held by 6 WorldCat member libraries worldwide

Statistical density and amplitude tapering are combined to improve the radiation characteristics of thinned, density tapered arrays by allowing changes in both element density and amplitude weight to better approximate the model amplitude distribution. Statistical density tapering (which uses only uniformly weighted elements) is extended so that each element is allocated one of several possible values of amplitude weight according to predefined selection probabilities. Increasing the number of possible values, or levels for amplitude weight can reduce the sidelobe levels of an array. Several choices of levels and their probabilities can reduce sidelobes and satisfy the extension criteria. One of the lowest sidelobe levels is produced if: (a) the amplitude levels are equi-spaced in the allowable range between zero and unity, and (b) their selection probabilities are terms from the binomial distribution of the appropriate order. The properties of arrays designed using equi-spaced amplitude levels with binomially distributed selection probabilities are calculated and described as a function of the number of levels and aperture size.

Experiments in variable frame rate analysis for speech recognition by S. M Peeling( Book )

3 editions published between 1989 and 1990 in English and held by 6 WorldCat member libraries worldwide

This memo describes the application of a simple VFR analysis to the RSRE Airborne Reconnaissance Mission (ARM) system. This is a continuous speech recognition system based on phone-level hidden Markov models (HMMs) which has been developed at the RSRE Speech Research Unit. This section will briefly describe the nature of the data, what VFR analysis is, and its application to automatic speech recognition. Assume that at any 'instant' in time the speech signal can be represented by an ordered set of numbers, or feature vector. This 'instant' is assumed to be short enough that the properties of the speech signal do not change significantly. Any utterance, or collection of words, can then be described as a succession of feature vectors (sometimes referred to as frames). There are areas where the speech signal is relatively constant and hence successive feature vectors will be very similar. In other areas the signal may change rapidly and hence successive feature vectors will be different. In order to reduce the processing time, one obvious solution is to reduce the data (frame) rate. However, parts of the signal which are changing rapidly contain valuable information and so need to be retained. For this reason it is necessary to employ some method of data reduction which actually depends on the data. Variable frame rate coding is such a technique. (JES)
On understanding in communicating systems and the error in the Chinese Room thought-experiment by T. A. D White( Book )

1 edition published in 1990 in English and held by 6 WorldCat member libraries worldwide

John Searle has proposed the Chinese Room thought-experiment to refute the notion of what he calls strong Al (Artificial Intelligence), that is that thinking is merely the manipulation of formal symbols. We discuss the Chinese Room thought-experiment, and show that Searle's argument is in error. We show, therefore, that the Chinese Room thought-experiment provides no grounds for the conclusion that computer hardware, solely on the basis of running computer software, can never be regarded as intelligent
A simulation study of landing time allocation procedures for use in computer-assisted air traffic management systems by A. J Budd( Book )

4 editions published in 1989 in English and held by 6 WorldCat member libraries worldwide

During busy periods at major airports, inbound aircraft have to queue for use of the landing runway. In future air traffic systems it is likely that controllers will be able to make use of computer-proposed landing sequences and speed control advice. One proposed method for allocating aircraft landing times in such systems is the 'Time Horizon' method. According to this method, a preferred landing time is calculated for each aircraft some way out from the airport, and a planned landing time is allocated at a fixed time before the aircraft's preferred landing time. This memorandum reports on a computer simulation study to demonstrate and quantify the effect of the time horizon method
A process monitor for the transputer by K. R Milner( Book )

4 editions published between 1991 and 1992 in English and held by 6 WorldCat member libraries worldwide

A brief survey of performance monitoring tools for parallel machines is given, followed by the particular problems of designing a performance monitor for the transputer. A new monitor process is then described, which outputs data such as process active time and communication waiting time for each process being monitored
On the design and implementation of a secure computer system by Phil F Terry( Book )

1 edition published in 1988 in English and held by 5 WorldCat member libraries worldwide

Smite is a novel computer architecture implementing a new security policy model which is proposed for use in Government and Military environments where high assurance of complex confidentiality and integrity based security policies is required. This report records results of a one year contract (A94c/2711) carried out by TSL Communications Ltd. This provided a peer review of the proposed architecture, characterized the essential architectural elements and formulated the security oriented top level model. In this way it provided a baseline definition of SMITE to aid the future way forward for the project. Keywords: Great Britain, Multiprocessors. (KR)
Object orientated simulation on transputer arrays using Time Warp by P Simpson( Book )

3 editions published in 1989 in English and held by 5 WorldCat member libraries worldwide

The successful application of Transputers to distributed event driven heterogeneous simulation using the Time Warp methodology is demonstrated with transputers and occam providing a natural vehicle for this class of simulation. The simulation technique basically comprises a number of communicating simulation object processes, with appropriate action being taken to ensure the correct chronological sequence of processed simulation events. Time Warp is particularly attractive, since it permits all parts of a distributed processor network to operate in parallel (although some of the computation may later be undone). The need for hardware control of memory management has not been identified, although the requirement for a deadlock free, random point to point communications strategy has. Great Britain. (rrh)
Binary pseudo random phase correlation in radar systems - a new approach by M Dean( Book )

3 editions published in 1989 in English and held by 5 WorldCat member libraries worldwide

The growing requirement for low probability of intercept characteristics in radar sensors is producing increasing interest in continuous wave (cw) radars. Pure cw radars have no inherent ranging capability, and it is therefore customary to modulate the cw transmission in some way if ranging is required. An increasingly popular modulation scheme is Binary Pseudo Random Phase Coding (BPRPC), whereby the phase of the transmitted signal is switched between O degs. and 180 degs. under the control of a binary pseudo random sequence of length n, variously known as a pseudo random code, maximal sequence or Galois Code. Techniques for achieving the correlation of binary pseudo random phase coded signals in doppler radar sensors are discussed. A new design based on current technology is developed which potentially offers both a low cost and highly integrable solution. Prototype hardware is constructed and tested and its performance compared with other designs. Excellent performance is achievable without the penalties of size and weight which the other designs carry. Australia. (RH)
