Tardis: A Numerical Simulation Package For Drive Systems, W. Suwanwisoot, C. M. Ong
Tardis: A Numerical Simulation Package For Drive Systems, W. Suwanwisoot, C. M. Ong
Department of Electrical and Computer Engineering Technical Reports
TARDIS is a digital computer simulation package originally intended to simulate drive systems. Its versatility has proved to be very useful in other areas as well. It is designed to replace the functionality of analog computers so that the user who cannot afford to have one can use the program on a personal or mainframe computer. The author believes that it is one of the most efficient and accurate simulation programs of its kind at this point even though not all of its potential has been exploited to. the fullest. It can handle index 0 and 1 differential-algebraic systems with …

In order to represent a digital image, a very large number of bits is required. For example, a 512 X 512 pixel, 256 gray level image requires over two million bits. This large number of bits is a substantial drawback when it is necessary to store or transmit a digital image. Image compression, often referred to as image coding, attempts to reduce the number of bits used to represent an image, while keeping the degradation in the decoded image to a minimum. One approach to image compression is segmentation-based image compression. The image to be compressed is segmented, i.e. the …

The problem of low-angle radar tracking utilizing an array of antennas is considered. In the low-angle environment, echoes return from a low flying target via a specular path as well as a direct path. The problem is compounded by the fact that the two signals arrive within a beamwidth of each other and are usually fully correlated, or coherent. In addition, the SNR at each antenna element is typically low and only a small number of data samples, or snapshots, is available for processing due to the rapid movement of the target. Theoretical studies indicates that the Maximum Likelihood (ML) …

Accurate knowledge of tissue temperature is necessary for effective delivery of clinical hyperthermia in the treatment of malignant tumours. This report compares computer-predicted versus measured intratumoral temperatures in 11 human subjects with intracranial tumours, treated with a conceptually simple 'conductive' interstitial hyperthermia system. Interstitial hyperthermia was achieved by the use of parallel arrays of implanted, electrically heated catheters. The tissue was warmed by thermal conduction and blood convection. Simulation of intratumoral temperatures was achieved by solving a modified bioheat transfer equation on a digital computer using a finite difference method. Comparison of intratumoral temperatures from simulations and measured values differed …
Optimal Code Scheduling For Multiple-Pipeline Processors, Ashar Nisar, Henry G. Dietz
Optimal Code Scheduling For Multiple-Pipeline Processors, Ashar Nisar, Henry G. Dietz
Department of Electrical and Computer Engineering Technical Reports
Pipelining the functional units and memory interface of processors can result in shorter cycle times and dramatic increases in performance, but only if the pipeline latency can be hidden by other useful operations. The portion of pipeline latency which is not hidden results in an extension of the total execution time, either implemented by hardware interlocks or by compile-time insertion of NOPs (Null Operations). By rearranging instructions, it is possible to minimize the total pipelined execution time, but the problem of finding this optimal code schedule is well known to be NP-complete. In this paper, we describe a code scheduler …
