In this paper, an approach is presented to automatically allocate a set of exploration tasks between a fleet of mobile robots. The approach combines a Road-Map technique and Markovian Decision Processes (MDPs). The addressed problem consists of exploring an area where a set of points of interest characterizes the main positions to be visited by the robots. This problem induces a long term horiz...

Map sheets are often used as basic spatial units for managing spatial data produced from paper maps. This often results in incompatibility between adjacent map sheets spatial objects do not cross the boundaries smoothly and even the boundaries themselves do not match their neighbors exactly. To solve the problem this paper proposes a computational procedure for making seamless map sheets. Line ...

The assumption of the work presented in this paper is the situatedness of the change process. The Enterprise Knowledge Development Change Management Method (EKD-CMM) provides multiple and dynamically constructed ways of working to organize and to guide the change management. The method is built on the notion of labeled graph of intentions and strategies called a road map and the associated guid...

Optimisation of oral bioavailability is a continuing challenge for the pharmaceutical and biotechnology industries. The number of potential drug candidates requiring in vivo evaluation has significantly increased with the advent of combinatorial chemistry. In addition, drug discovery programmes are increasingly forced into more lipophilic and lower solubility chemical space. To aid in the use o...

Over the past two decades, our knowledge of ecological impacts roads has increased rapidly. It is now clear that environmental effects transportation infrastructure are inextricable from benefits to economic, social, and cultural values. Despite necessity optimizing these multiple values, road planners, scientists, practitioners have no established methodology or pluralistic approach address gr...

A typical way to update map is to compare recent satellite images with existing map data, detect new roads and add them as cartographic entities to the road layer. At present image processing and pattern recognition are not robust enough to automate the image interpretation system feasible. For this reason we have to develop an image interpretation system that rely on human guidance. More impor...

Outdoor mobile robotised vehicles currently hold the attention of many researchers because they can bring solutions to many applications related to transport of passengers in urban environments. An example of robotised vehicle is the CyCab (Bom et al., 2005). Transport applications which can combine mono or multi vehicle operating mode are most efficient. For autonomous navigation application, ...

The road layout problem consists of finding a valid road layout between two locations described by their azimut and tridimensional coordinates in a topographical map. Valid layouts should comply with certain road design regulations that normally depend on design parameters such as road speed and type (e.g. highway, or conventional road). The paper presents a discrete state space for this proble...
