Analysis of psychological education factors based on computer software and hardware collaboration and data mining

Psych education is a process of development through which he gradually adapts himself to his physical and mental environment in various ways, through which he grew up from childhood to adulthood. This feature provides students with a profile of how their behavior and academic performance are affected in their educational life. At this stage of software and hardware development, analyzing data mining is difficult to analyze at the level of psychological education. More accurate and timely delivery of computer hardware and software integration can help with these issues and contracts with leads in the previous system. Therefore, the proposed Deep Learning studies recommend using data mining techniques to provide open issues, current related solutions, and computer software and hardware recommendations. The proposed results emphasized the importance of using new educational model mining techniques for data related to students' psychological evaluation. Educational psychology has accumulated some observations in computational students. In contrast, psychology is relevant to computer education and emphasizes a wide range of topics related to different psychological education stages to discussions deep learning. In this review, a data collection of randomly calculated psychological databases of applications is based on stochastic pattern recognition analysis. The proposed technology includes computer software and hardware collaboration that provide psychological education to retrieve data similar to different pre-stored data types.     

Generating software test data by evolution

This paper discusses the use of genetic algorithms (GAs) for automatic software test data generation. This research extends previous work on dynamic test data generation where the problem of test data generation is reduced to one of minimizing a function. In our work, the function is minimized by using one of two genetic algorithms in place of the local minimization techniques used in earlier research. We describe the implementation of our GA-based system and examine the effectiveness of this approach on a number of programs, one of which is significantly larger than those for which results have previously been reported in the literature. We also examine the effect of program complexity on the test data generation problem by executing our system on a number of synthetic programs that have varying complexities

Testing closed source software: computer forensic tool case study

Computer forensic techniques are important for the prevention, detection, and investigation of electronic crime. Computer forensic investigators need computer forensic tools to produce reliable results that meet legal requirements and are acceptable in the courts. Most of these tools are closed-source, making the software a black-box for testing purposes. This paper illustrates a different black box testing method for experimenting computer forensic tools based on functional scenarios.     

The computer in the consulting room: a psychological framework

Abstract

The use of an interactive computer system to aid the doctor with history taking and diagnosis is described. The system is developed for dyspepsia cases and is designed to be flexible enough to give the doctor considerable choice in the way it is used in the consulting room. We have observed and analysed its use by doctors in two very different settings; registrars and SHOs in an outpatient clinic, and GP trainers in a simulation exercise. All the doctors found individual ways of using the computer in the consultation, some chose to use it ‘conversationally’, alternating their attention between patient and computer, whilst others attempted to minimize its use while the patient was present. Patients’ reactions to the use of computers in general, and to their experience of this system specifically are described. The ways in which the computer imposes structure on the consultation and seems to influence the doctors’ decision processes are discussed. The complex dynamics of the interaction between patient, doctor and computer are outlined and are related to the cognitive load imposed. We raise ‘human factors’ issues, specific to the medical consultation environment, which need consideration in the design of future systems.

The new software documentation standard: Report on the joint logistic commanders joint policy coordinating group on computer resource management, computer software management subgroup, software workshop

Under the aegis of the Joint Logistics Commanders, the Computer Software Management Subgroup organized two workshops of combined industry and military personnel to review, revise, and recommend new standards for the acquisition and documentation of embedded computer systems. This paper describes the superset of documents which will be required under the new MIL-STD-SDS. The relationship of each document to the acquisition cycle, particularly the design reviews, and to each other, is emphasized.     

The maintenance, distribution and development of biomedical computer software: an exercise in software engineering

The growing reliance of biomedical investigations on computer software in almost all facets of their work places considerable emphasis on the need for the integrated management of the software. In order to efficiently develop, distribute, and maintain the software, tools are required which not only automate these tasks but also, wherever possible, 'semi-intelligently', alert their user to irregular situation. We describe an assortment of such tools routinely used in the management of the SAAM/CONSAM biokinetic software and illustrate their application. Furthermore, using these techniques we have presented some comparative performances of numerical integrators and of computer processors.
