The goals of the chip are to improve both the speed and the density as compared to an off-the-shelf implementation. The complex control sections of the chip were synthesized from a functional description into standard cells, while critical-path arithmetic sections were custom designed. This mix of full custom and standard cell design allows for a trade-off between design time and area, with no penalty in speed performance. The resulting silicon chip, implemented in 1.1 mu m CMOS technology, is useful for ECG data collection, compression, and analysis.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

A typical PACS consists of a database of medical images, display stations, acquisition systems, and a communication medium. The proposed model is for the delay analysis of the image database, the communication channels, and the picture viewing stations (PVSs). Performance curves are presented for the delay in retrieving images from the database, in the transmission of images, and in processing them in the image processor. The mean delay (that is, the time it takes for a radiologist to view a medical exam from the moment that a request packet is sent to the image database till the time the images are received) is the sum of all the delays mentioned above. The distributions of these delays can be easily evaluated and plotted by using the inverse of the Laplace transforms. From the curves provided, the end-to-end delay for various amounts of load in the system can be accurately estimated.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

This technique is based on back-to-front and front-to-back hidden surface removal algorithms which reduce image rendering time by adaptive rendering termination.

Using these two algorithms, a technique for allowing each processor to dynamically and independently select the fastest volume rendering algorithm based on its local processing circumstances is described.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

Given a knowledge base file of relative weights for the input features of a group of medical conditions, a user can enter features of individual cases interactively or in either of two streamlined modes. A case can be saved in or retrieved from a file, and the disease probabilities calculated from the knowledge base can be displayed on the screen at any time. Finally, a batch mode permits rapid processing of large numbers of cases whose features are contained in a single disk file. The diagnostic probabilities for each case are written to a collection output file. This Bayesian shell permits rapid evaluation of Bayesian knowledge bases in support of knowledge base and program development. It can be embedded in other programs that utilize Bayes' theorem to evaluate any body of data, clinical or otherwise.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

There are three possible standards for home automation. In Europe, ESPRIT will be used. In Japan, the Home Bus System will be used. At present the BSR X-10 system is probably the most widely used system in the US, but if there is wide support for the CEBus standard by industry, then it is likely that the CEBus microchips will be built into US appliances in the future.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

BTDS consists of an expert system and a learning system. The former can help diagnosticians in judging the causes of brain tumors according to computed tomography pictures, and the latter, based on a revised inductive learning method, is especially suitable in the case of brain tumors. By applying the proposed learning mechanism, the initial knowledge base can be constructed and new rules can be learned from noise data in the process of inference. The consideration and process of system implementation is introduced, and the learning mechanism is presented. An example is given to illustrate BTDS, and the test results are shown to evaluate the performance of the system.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

It addresses safety issues from the concept stage forward and provides early identification of the systematic failures due to errors in the design, construction, or use of the system which cause it to fail under particular combinations of conditions. Early identification of hazards allows cost-effective implementation of safety requirements to control the effects of the hazardous effects. In addition, the results of the analysis have been used to determine completeness of software testing and to limit the number and amount of test cases with confidence. This work describes the procedure for performance hazards analysis, and the method to use the risk and probability assessment to determine the level of testing to report, with confidence, the results of testing. Application of this analysis has shown the practicality of this approach.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

Evaluated in studies of the human calf and thigh during 90 min of 6 degrees or 10 degrees head-down bed rest, the system promises to enable tracking of segmental and compartmental fluid redistribution in response to various environmental and physiological stresses with both temporal and anatomic resolution greater than that attainable with other methods.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.
