Vision-based systems for remote surveillance usually involve change detection algorithms for intruders, obstacles or irregularities detection. Real time applications require simple, fast and reliable algorithms for change detection methodology. Morphological change detection algorithm satisfies these requirements. Threshold is a very important issue for morphological change detection. Threshold...

the aim was to compare the predictive power for type 2 diabetes mellitus (t2dm) using dynamic change (difference) of metabolic syndrome (ms), difference of fasting plasma glucose (fpg), baseline ms and fpg in cohort study.overall, 3461 subjects were recruited from prevention of multiple metabolic disorders and ms in jiangsu of china study with 3.8 years follow-up. cox proportional-hazards regre...

nowadays, it is common to find optimal point of the dynamic problem; dynamic problems whose optimal point changes over time require algorithms which dynamically adapt the search space instability. in the most of them, the exploitation of some information from the past allows to quickly adapt after an environmental change (some optimal points change). this is the idea underlining the use of memo...

A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...

The Human Development Report 2007/2008 about climate change and development made bold arguments concerning human rights and justice for poor and disadvantaged populations. However, its policy proposals were less bold, looking very similar to those of the World Bank's World Development Report 2010. This article investigates in which direction the thinking on environment and sustainability by UND...

In this paper, critical realism and activity theory are compared within the context of theorizing technology-mediated organizational change. An activity theoretic analysis of the implementation of large-scale disruptive information systems in a public sector setting (in particular concerning paramedic treatment of heart attack patients and ambulance dispatch work activity) is used to illustrate...
