Application of computer image processing in office automation system

With the development of science and technology, a variety of office automation systems (OAS) has been extensively applied in various occasions. Moreover, digital image processing technology has made great progress. The emergence of a series of excellent algorithms represented by Adaboost human face detection algorithm extends the application space of digital image processing in daily work and study. Besides, the operational capability of existing personal computers enables them to run smoothly these algorithms, which further contributes to the technological maturity of the digital image processing associated office automation systems. To keep up with the pace of information technology, this study selects high definition (HD) technology for paper archives in OAS, which is related to digital image processing as the research content. Automatic high definition demonstration of paper archives can reduce the burden on staff. This paper solved the problems of correction of slanted document image, automatic extraction of identification photo and color enhancement of seal and verified the feasibility of the scheme.

Operational definitions for system requirements as the basis of design automation

This paper introduces formal definitions to system requirements as the basis of design automation. Semi-formal requirements for real-time systems are expressed in the form of system verification diagrams, and the graph model of behaviour represents the design, capturing three aspects of system behaviour—control, data and interpretation. The design model is considered operational as an underlying token machine governs its actual behaviour. To achieve automatic design synthesis, the semantics of each construct in the requirement model have to be formally defined. These definitions constitute the core of a knowledge base in an automatic design synthesis tool.     

The impact of a computerized conferencing system on the productivity of scientific research communities

This is a case study of five scientific research communities which used EIES (the Electronic Information Exchange System, a computerized conferencing system) for 2 years. Relying primarily upon the subjective reports of the participating scientists, it describes: (i) increases in 'connectivity' (the size and density of the communication networks in which the scientists are embedded); (ii) qualitative changes in the ways in which the scientists think and work; and (iii) reported changes in such productivity-related factors as increases in the available 'stock of ideas' and in the availability of references and other information useful in their work.     

The impact of a computerized conferencing system on the productivity of scientific research communities

Researchers and practitioners in the field of information and communication technologies (ICT) have for a while been embracing the concepts of user and consumer experience as well as emotions in design, encouraging the industry to emphasise hedonic and symbolic qualities of products and services, over and beyond their utilitarian characteristics. However, the idea that mobile phone users, for instance, seek increasingly experience-rich, personalised products can not be taken for granted. Therefore, it is valuable to investigate the degree to which users really share designers' increasingly socio-emotional stances. The presented longitudinal study investigated users' mobile phone-related product meaning, particularly its development from 2004 to 2008. Product meaning was conceptualised in terms of an affective-cognizant choice mode dimension complemented by items capturing utilitarian, hedonic, and symbolic facets of the construct. The findings provide grounds for raising an important discussion about a possible pragmatic shift in product meaning, away from emotional and holistic, towards piecemeal and rational valuation. This would obviously challenge current design maxims. Linking these results to users' personality and mobile phone ownership history, subgroups with notably dissimilar product meaning development could be distinguished mainly with regard to levels of neuroticism, extraversion and brand loyalty – however, not gender.
