Object-orientation has rapidly become accepted as the preferred paradigm for large scale system design. There is considerable literature describing approaches to object-oriented design and implementation. However discussion of testing in an object-oriented environment has been conspicuous by its absence. At first sight it appears that decomposition of a system into a potentially large number of information-hiding classes greatly increases the cost of testing. However in this paper we show that by taking an object-oriented approach to testing, and the inclusion of appropriate tools in the development environment, testing time can be greatly reduced and special purpose test code can be virtually eliminated.

This paper deals with methods of automated memory synthesis for Custom Computing Machines (CCMs). We focus the presentation on the synthesis of interleaved memory systems, which provide the quickest access to data at the cost of more parallel hardware. The synthesis of an interleaved memory system starts with the analysis of data access patterns in the algorithm, from which a number of possible storage schemes is derived. The storage scheme defines how the array elements can be distributed among different memory banks. The best storage scheme is then chosen according to a complex metric of cost and performance of the required memory system. This metric involves the schedule length of operations, the type and number of required memory chips, the cost and delay of address generation and the interconnection network. Results of our experiments demonstrate that the developed methods are capable to automatically synthesise storage schemes and interleaved memory systems, which are the same or better than those previously conceived by an experienced hardware designer.

In an attempt to propose a robust method for understanding natural language (NL) interface commands, a scheme is proposed that infers intentions from an indirect speech-act that does not express users' real intentions explicitly. This method classifies the real intentions of the indirect speech-act into: 1) refusal;2) reversal;3) restriction;4) benefit;and 5) disability. Further, concepts are abstracted for operations, e.g., displaying, moving, and deleting information systems;and constructing the operation knowledge base. This knowledge based comprises operational concepts and the relationships between them. These relationships are assigned the foregoing classifications for intentions. In addition, we construct the knowledge base of objects for the target of operations, e.g., files, figures, strings. This knowledge base contains the relationships: a) antonym;b) exclusive;c) part-of, between the objects;and uses these relations to infer the transitions between the objects. An algorithm is the proposed to infer concepts for operations and concepts for target objects of operations that may represent the user's actual intentions. This proposal scheme was tested with requests on UNIX and a commercially available Japanese Word Processor. The system successfully inferred the intentions for approximately 80 percent of the user's indirect speech-act.

AbstractIn this article a multimedia computer‐assisted learning (MCAL) system is presented. The major objective of this work was to investigate the potential of using such systems as tools for transferring instructional course information through various types of computer media as opposed to the classic CAL systems. The philosophy and techniques employed to design the system are investigated. Usage of the implemented system and its merits have been illustrated through its application to teach engineering students and technicians the theory and concepts of marine radar. System design, implementation, test, and revision phases are presented and discusse

Classical signal processing functions such as spectrum analysis, correlation, convolution, filtering, mixing, and noise reduction can be performed optically using optical signal processing devices and systems. The signal media, i.e., light waves, not only have a higher information-carrying capacity than electrical wires, but may pass through each other without interference, thus providing an increased interconnection capacity. This property facilitates improved communication and ease of reconfiguration between processing elements in highly parallel optical computing architectures.1

Recent years have witnessed an increasing prevalence of wearable devices in the public, where atrial fibrillation (AF) detection is a popular application in these devices. Generally, AF detection is performed on cloud whereas this paper describes an on-device AF detection method. Technically, compressed sensing (CS) is first used for electrocardiograph (ECG) acquisition. Then QRS detection is proposed to be performed directly on the compressed CS measurements, rather than on the reconstructed signals on the powerful cloud server. Based on the extracted QRS information, AF is determined by quantitatively analyzing the (RR, dRR) plot. Databases with ECG samples collected from both medical-level (MIT-BIH afdb) and wearable ECG devices (Physionet Challenge 2017) are introduced for performance validation. The experiment results well demonstrate that our on-device AF detection algorithm can approach the performance of those implemented on the raw signals. Our proposal is suitable for AF screening directly on the wearable devices, without the support of the data center for signal reconstruction and intelligent analysis.
