Conference Report: Microprocessors in Automation and Communications

As befits the mother of the democracies, debate on the role the microprocessor is to play in Great Britain is vigorous. Even the Prime Minister, James Callaghan, has joined the fray, telling the Labour Party conference at Blackpool that the microprocessor exemplifies the kind of technological change Britain must accommodate in the 1980's.     

Hybrid expert systems: A survey of current approaches and applications

This paper is a statistical analysis of hybrid expert system approaches and their applications but more specifically connectionist and neuro-fuzzy system oriented articles are considered. The current survey of hybrid expert systems is based on the classification of articles from 1988 to 2010. Present analysis includes 91 articles from related academic journals, conference proceedings and literature reviews. Our results show an increase in the number of recent publications which is an indication of gaining popularity on the part of hybrid expert systems. This increase in the articles is mainly in neuro-fuzzy and rough neural expert systems’ areas. We also observe that many new industrial applications are developed using hybrid expert systems recently.     

MLP-based radar detectors for Swerling 1 targets

This paper deals with the application of Multilayer Perceptrons to radar detection. The dependence of the neural detector performance on the network size and on the signal-to-noise ratio selected for training is considered. Multilayer Perceptrons with different numbers of neurons in the hidden layer have been trained using different values of the signal-to-noise ratio to minimize the mean square error using the error back-propagation algorithm. Results show that the higher the number of hidden neurons, the closer the neural detector to the Neyman-Pearson optimum detector and the lower the dependence of the Multilayer Perceptron performance on the signal-to-noise ratio selected for training. Due to its practical interest, the very low probability of false alarm values has been considered. To estimate the probability of a false alarm, importance sampling techniques have been used in order to reduce the computational cost of maintaining a low relative error.

A systematic literature review of software requirements prioritization research

ContextDuring requirements engineering, prioritization is performed to grade or rank requirements in their order of importance and subsequent implementation releases. It is a major step taken in making crucial decisions so as to increase the economic value of a system.ObjectiveThe purpose of this study is to identify and analyze existing prioritization techniques in the context of the formulated research questions.MethodSearch terms with relevant keywords were used to identify primary studies that relate requirements prioritization classified under journal articles, conference papers, workshops, symposiums, book chapters and IEEE bulletins.Results73 Primary studies were selected from the search processes. Out of these studies; 13 were journal articles, 35 were conference papers and 8 were workshop papers. Furthermore, contributions from symposiums as well as IEEE bulletins were 2 each while the total number of book chapters amounted to 13.ConclusionPrioritization has been significantly discussed in the requirements engineering domain. However, it was generally discovered that, existing prioritization techniques suffer from a number of limitations which includes: lack of scalability, methods of dealing with rank updates during requirements evolution, coordination among stakeholders and requirements dependency issues. Also, the applicability of existing techniques in complex and real setting has not been reported yet.

Progress in stylistics: Theory, statistics, computers

This paper attempts to assess the progress made in computational stylistics dyring the course of the past twenty-five years. First, we discuss some theoretical notions of style, and then we sketch certain trends that emerge from relevant articles appearing in a variety of publications including conference proceedings and academic journals (other than CHum). The conclusion is that progress has been mixed.Louis T. Milic is professor emeritus of English at Cleveland State University and secretary-treasurer of the Dictionary Society of North America. He has been active in quantitative stylistics since the 1960s and has recently completed work on the second of two period corpora, the Century of Prose Corpus.     

A systematic review of research on open source software in commercial software product development

Context

The popularity of the open source software development in the last decade, has brought about an increased interest from the industry on how to use open source components, participate in the open source community, build business models around this type of software development, and learn more about open source development methodologies. There is a need to understand the results of research in this area.

Objective

Since there is a need to understand conducted research, the aim of this study is to summarize the findings of research that has ben carried out on usage of open source components and development methodologies by the industry, as well as companies’ participation in the open source community.

Method

Systematic review through searches in library databases and manual identification of articles from the open source conference. The search was first carried out in May 2009 and then once again in May 2010.

Results

In 2009, 237 articles were first found, from which 19 were selected based on content and quality, and in 2010, 76 new articles were found from which four were selected. Twenty three articles were identified in total.

Conclusions

The articles could be divided into four categories: open source as part of component based software engineering, business models with open source in commercial organization, company participation in open source development communities, and usage of open source processes within a company.

The economics of software process improvement

Software process improvement is gaining momentum throughout the software industry. Many cities now have nonprofit SPIN (Software Process Improvement Network) groups. In a visible sign that process improvement is now a mainstream technology, SPIN's national conference in Boston last spring drew several thousand attendees. Another sign is the frequency of journal articles devoted to process improvement. However, as often happens with software, process improvement articles tend to be theoretical. Comparatively little solid, empirical data is being published on three important topics: what does it cost to improve software processes? How long will it take to make tangible improvements? What kind of value can be expected in terms of better quality, productivity, or user satisfaction? The paper condenses some of my findings, which are based on studies of leading software producers in the United States, Europe, South America, and the Pacific Rim

This bibliography attempts to compile all articles, books, conference papers, and technical reports about computer graphics and man-machine interaction that have been published in English from 1970 to 1975. Because the literature pertaining to computer graphics and man-machine interaction is immense, this bibliography will no doubt be incomplete. Suggestions and contributions for future supplements to the bibliography should be sent to the compiler.     

The Center of History

If we are writing real history, we are proving the worth of our efforts by answering the fundamental question of existence: "So what?" History tells us why we should care about things, why certain ideas are important and others are not. This issue contains articles on the history of computing from a conference sponsored by the Charles Babbage Institute that was organized in honor of retiring director Arthur Norberg. In addition, the issue features a second article on the development of computing at the University of Maryland.     

Speech emotion recognition research: an analysis of research focus

This article analyses research in speech emotion recognition (“SER”) from 2006 to 2017 in order to identify the current focus of research, and areas in which research is lacking. The objective is to examine what is being done in this field of research. Searching on selected keywords, we extracted and analysed 260 articles from well-known online databases. The analysis indicates that SER research is an active field of research, dozens of articles being published each year in journals and conference proceedings. The majority of articles concentrate on three critical aspects of SER, namely (1) databases, (2) suitable speech features, and (3) classification techniques to maximize the recognition accuracy of SER systems. Having carried out association analysis of the critical aspects and how they influence the performance of the SER system in term of recognition accuracy, we found that certain combination of databases, speech features and classifiers influence the recognition accuracy of the SER system. We have also suggested aspects of SER that could be taken into consideration in future works based on our review.
