Typically such systems require the simultaneous capture and archival of large amounts of data from multiple sources and media. The data must be captured, combined and archived together in a way that makes accurate reproduction possible. The proposed design can be implemented in Windows/NT using readily available technology. The success of the implementation depends on the integration of standard hardware to the analogue sources using custom interfaces. The software development effort requires the creation of graphical user interfaces, client/server architectures, and real-time kernel-mode drivers.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

This paper describes the design and development of a multicarrier demodulator using four Texas Instruments TMS320C40 processors. In this application, a commercial DSP board is configured to demodulate a multicarrier FSK signal having eight parallel channels, with a variety of modulation parameters. The goal of the present work was to harness the power of parallel processors with the expectation that more elaborate demodulation schemes could be tackled in the future through the use of enhanced algorithms deployed on each of the DSP modules.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

A significant reduction in the size of the input and the output filters, the transformer and magnetics is achieved by increasing the switching frequency. However, in hard switched converters, this also increases the switching losses. To reduce the switching losses this paper proposes an AC power supply topology with back-up capabilities based on the series parallel half-bridge resonant converter. The main features of the proposed configuration includes: (i) isolation with a single transformer; (ii) zero voltage switching in the high frequency converters; and (iii) unity input power factor. Operating principles and static characteristics of the converter are derived. Finally, proof-of-concept for the proposed converter is experimentally verified.","PeriodicalId":359446,"journal":{"name":"CCECE '97. Canadian Conference on Electrical and Computer Engineering.

Methods, which are employed presently, precompute image indices, which are deemed to be statistical representations of image information. Queries of colour, shape, texture, etc., are then performed directly on these indices to find valid images. The authors propose a new indexing technique which calculates the multidimensional histogram of the directional detail in a given image. They apply wavelet theory and multiresolution analysis to extract the directional information from an image and then map this information into 3-dimensional vectors. Histograms of these vectors are then calculated at different levels of resolution, allowing progressive image query using colour histogram techniques to be directly applied. The technique is capable of querying and searching a database for images based on attributes such as smoothness, randomness and horizontal, vertical and diagonal edges at varying resolutions.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

Its computational requirements are of the order of K.M.N (the maximum lags and the number of data points respectively) and in any practical situation this amounts to a significant burden. The algorithm we present in this paper exploits the redundancy of the product terms to derive a factored expression for C[k,m] that results in a reduced number of multiplications (and overall operations). The savings depend on the relationships between the 2 lags and the number of data samples. Details for each case are provided and numerical examples illustrate the algorithm's effectiveness.","PeriodicalId":359446,"journal":{"name":"CCECE '97.

Although Marconi's experiment has been analysed by many researchers, the focus has only been on the circuit theory part. But here in this work we have studied it from the antenna and the ionospheric propagation points of view. Marconi claimed that he had used signals with a frequency of 0.166 MHz. Using his antenna design and ionospheric conditions prevailing at that time the present work proves that signals with frequencies of 9.375 MHz and 12.5 MHz had much higher possibility of transatlantic transmission rather than his much reported frequency. We have also shown that if the experiment was done in summer the possibilities of success would have been even less.","PeriodicalId":359446,"journal":{"name":"CCECE '97.
