  • A novel video smoke detection method using both color and motion features is presented. The result of optical flow is assumed to be an approximation of motion field. Background estimation and color-based decision rule are used to determine candidate smoke regions. The Lucas Kanade optical flow algorithm is proposed to calculate the optical flow of candidate regions. And the motion features are calculated from the optical flow results and use to differentiate smoke from some other moving objects.

  • In this paper, we study the problem of complex event detection (CED) in a monitoring environment that consists of potentially a large number of distributed event sources (e.g., hardware sensors or software receptors). CED is becoming a fundamental capability in many domains including network and infrastructure security (e.g., denial of service attacks and intrusion detection [22]) and phenomenon and activity tracking (e.g., fire detection, storm detection, tracking suspicious behavior [23]).

  • Landmines and explosive remnants of war (ERW), which include unexploded ordnance (UXO) and abandoned explosive ordnance, represent a major threat to civilian. This demands that all the mines and ERW affecting the places where ordinary people live must be cleared, and safety of people in areas that have been cleared must be guaranteed.

  • Before the days of mass literacy, medicine was more art than science, and people recognized a pharmacy by the four traditional colored bottles that represent earth, fire, air, and water. Medicine has come a long way since the days of the apothecary with its impressive collection of powders and bottles; drugs today are highly regulated and must comply with standards set by the U.S., Europe, Japan, and other countries. A drug must be shown to be efficacious and meet rigorous standards of purity, composition, and potency before being approved for use in the patient populatio...

  • More than half of the world's population relies on solid fuels, including biomass fuels (wood, charcoal, dung, agricultural residues) and coal, to meet their basic energy needs. Cooking and heating with solid fuels on open fires or traditional stoves results in high levels of indoor air pollution. Globally, indoor air pollution is responsible for approximately 1.6 million deaths every year. Various interventions are available to reduce indoor air pollution and associated health impacts at the household level.

  • Second, board members in these small organizations often do double duty. One mo- ment they are directors who set policy and supervise the executive. The next moment, they are volunteer staff who greet new clients, stuff envelopes, or run the phone tree for the annual fundraiser. This is an inherent and unavoidable conflict of interest (though it is manageable). The board members are supervising the executive in their policy role, and doing the executive’s bidding in their staff volunteer role.

  • In addition to this exhaustive analysis, an estimation tool it has been built, since in most of the cases the performance of a network can only be known after deployment in a particular environment. If some problems are detected they will need to be solved in a second iteration. Therefore, an estimation tool was considered relevant for these situations in order to guide the network designer, and also for the selection of the furniture materials. In this work, we try to solve this problem by proposing a Computer-Aided Design (CAD) software tool for non-expert users.
