To realize quick and robust fire detection with image information of real scenes, smoke is a key feature information in detection methods. Since smoke does not keep stationary shape, it is difficult apply ordinal image processing techniques such as the edge or contour detection directly. Image information of smoke is also affected from its environmental conditions such as illumination changes a...

We utilize the situation calculus to develop a logical model of hypertext systems. The work builds upon the earlier work of Bieber and Kimbrough in the logical modeling of hypertext systems. In our presentation, a particular version of the situation calculus (which includes a language for programming complex actions) developed for the modeling of dynamic worlds and for the control of robotic ag...

Mathematical models for the electrical activity in cardiac cells are normally formulated as systems of ordinary differential equations (ODEs). The equations are nonlinear and describe processes occurring on a wide range of time scales. Under normal accuracy requirements, this makes the systems stiff and therefore challenging to solve numerically. As standard implicit solvers are difficult to im...

Water quality management policies on a river basin scale are of special importance in order to prevent and/or reduce environmental pollution caused by human sources. Industrial effluents are a priority issue particularly in Urban Wastewater Systems (UWS) that receive mixed household and industrial wastewaters, apart from rainfall water. In this paper, we present an analysis and implementation o...

Shapiro et al. [2005; 2006], presented a framework for representing goal change in the situation calculus. In that framework, agents adopt a goal when requested to do so (by some agent reqr ), and they remain committed to the goal unless the request is cancelled by reqr . A common assumption in the agent theory literature, e.g., [Cohen and Levesque, 1990; Rao and Georgeff, 1991], is that achiev...

nowadays, most of the cities, especially metropolises of developing countries are engaged with environmental issues like air and water pollution, waste increase and etc., that lead to the environmental destruction. meanwhile sustainable urban development, provides the balance between development and the environment, and supplies the current generation needs while keep its eyes on the next gener...
