In this paper, a Cognitive Vision System (CVS) is presented, which explains the human behaviour of monitored scenes using naturallanguage texts. This cognitive analysis of human movements recorded in image sequences is here referred to as Human Sequence Evaluation (HSE) which defines a set of transformation modules involved in the automatic generation of semantic descriptions from pixel values....

This paper proposes the use of a modular robotic architecture in order to produce feasible robots using evolution. To this end, the main requirements the architecture must fulfill are analyzed and a top-down methodology is employed to obtain the different types of modules that make it up. Specifically, the problem of how to increase the evolvability or evolution friendliness of the system is ad...

A composition procedure for linear and nondeleting extended top-down tree transducers is presented. It is demonstrated that the new procedure is more widely applicable than the existing methods. In general, the result of the composition is an extended top-down tree transducer that is no longer linear or nondeleting, but in a number of cases these properties can easily be recovered by a post-pro...

Top-down total quality management (TQM) programs often fail to create deep and sustained change in organizations. They become a fad soon replaced by another fad. Failure to institutionalize TQM can be attributed to a gap between top management’s rhetoric about their intentions for TQM and the reality of implementation in various subunits of the organization. The gap varies from subunit to subun...

Despite the current interest in Open Data publishing, a formal and comprehensive methodology supporting an organization in deciding which data to publish and carrying out precise procedures for publishing high-quality data, is still missing. In this paper we argue that the Ontology-based Data Management paradigm can provide a formal basis for a principled approach to publish highquality, semant...

Ahstrucf.-Despite considerable investigation of stream systems, the influence of fish predation on macroinvertebrate assemblages is still poorly understood and remains a controversial subject. We conducted a field experiment in an intermittent reach of Alum Creek in the Ouachita Mountains, Arkansas, to examine the effects of predatory fish on macroinvertebrate assemblages. We tested the predict...

The aim of the research was to explore the experiences of consultants during the implementation stages of a major IT programme in a UK health care organisation and to explain what factors affected the adoption of the new technologies. A single site case study approach using semi-structured interviews and project documentation was employed. The data was analysed using a method similar to Templat...

The small screens on increasingly used mobile devices challenge the traditional visualization methods designed for desktops. This paper presents a method called “Radial Edgeless Tree” (RELT) for visualizing trees in a 2-dimensional space. It combines the existing connection tree drawing with the space-filling approach to achieve the efficient display of trees in a small geometrical area, such a...

Many have questioned the reliability and accuracy of Wikipedia. Here a different issue, but one closely related: how broad is the coverage of Wikipedia? Differences in the interests and attention of Wikipedia’s editors mean that some areas, in the traditional sciences, for example, are better covered than others. Two approaches to measuring this coverage are presented. The first maps the distri...
