All over the world traffic injuries and fatality rates are increasing every year. The combination of negligent and imprudent drivers, adverse road and weather conditions produces tragic results with dramatic loss of life. In this scenario, the use of mobile robotics technology onboard vehicles could reduce casualties. Obstacle motion tracking is an essential ability for car-like mobile robots. ...

The use of computer communication networks has been rapidly increasing recently to 1) share expensive hardware and software resources, and 2) provide access to main systems from distant locations. The reliability and the cost of these systems are important considerations that are largely determined by placement of the nodes and the links between nodes. In this study, a genetic algorithm (GA) is...

Coverage is critical for wireless sensor networks to monitor a region of interest and to provide a good quality of service. In most cases we need to achieve full coverage which means every point inside the region (excluding the obstacles) must be covered by at least one sensor. The problem of placing the minimum number of sensors to achieve full coverage for a region with obstacles is NP-hard. ...

introduction: for cultural development and growth of a community, the participation of all individuals, including physically disabled people are required. in this study, the compliance rate of public and academic libraries and information centers’ building and equipment in zanjan, iran was determined according to the international standards for the physically handicapped, from the perspective o...

This paper considers the political economy of tobacco regulation-that is, the interplay between politics and markets in tobacco regulation. In surveying the interest-group politics of tobacco control, it describes political advantages held by a profitable and concentrated industry engaged in tobacco production. It also considers reasons for the surprising political success of tobacco control ad...

In this paper we have presented a novel technique for the navigation and path formulation of wheeled mobile robot. In a given environment having obstacles, a path is generated from the given initial and final position of the robot. Based on the global knowledge of the environment a global path is formulated initially. This global path considers all the known obstacles in the environment and mus...

Protein search for specific sequences on DNA marks the beginning of major biological processes. Experiments indicate that proteins find and recognize their targets quickly and efficiently. Because of the large number of experimental and theoretical investigations, there is a reasonable understanding of the protein search processes in purified in vitro systems. However, the situation is much mor...

To obtain minimum time or minimum energy trajectories for robots it is necessary to employ planning methods which adequately consider the platform’s dynamic properties. A variety of sampling, graph-based or local recedinghorizon optimisation methods have previously been proposed. These typically use simplified kino-dynamic models to avoid the significant computational burden of solving this pro...
