Future collision avoidance systems for crossing- scenarios depend on a reliable vehicle-to-vehicle communication link. Consequently, a deeper insight into inter-vehicle communication performance at intersections is needed. This paper presents three intersection categories for non-line-of-sight communication scenarios, based on a large measurement data set. For each category, packet delivery rates...
This paper puts forward PartiSim which is a participative framework for discrete event simulation (DES) consisting of six stages that span from the study initiation to implementation. Four of these stages involve facilitating the group of stakeholders in a workshop environment. These workshops enable collaboration by providing a forum for discussion and information sharing with the view to gaining...
Although high-resolution remote sensing (RS) images can supplement the reference map's deficiency in LADAR (Laser Radar) referenced navigation system over plain area, their different imaging modes still leave great errors' introduction into the positioning process. As positioning is commonly accomplished by matching the edges extracted as the obvious terrain characteristics, exploring automatic procedure...
We address the specification and the formal analysis of systems involving multiple facets. This leads to heterogeneous specifications that cover the different facets of these systems. A method, multifacet specification and analysis, is proposed to master the heterogeneity of systems by considering an abstract reference model that is referred to as a semantic reference for the specific models which...
We present a component-based description language for heterogeneous systems composed of several data flow processing components and a unique event- based controller. Descriptions are used both for generating and deploying implementation code and for checking safety properties on the system. The only constraint is to specify the controller in a synchrounous reactive language. We propose an analysis...
