In this paper, an extension of the Lafferriere–Sussmann algorithm of motion planning for driftless nilpotent control systems is analyzed. It is aimed at making more numerous admissible representations of motion in the algorithm. The representations allow designing a shape of trajectories joining the initial and final configuration of the motion planning task. This feature is especially importan...

A planning checklist for widespread severe acute respiratory syndrome, modeled on an Association of State and Territorial Health Officials (ASTHO) pandemic influenza planning checklist, was developed jointly by ASTHO, the National Association of County and City Health Officials, and the Centers for Disease Control and Prevention. This checklist, distributed May 2003, has been widely used.

conclusions higher prevalence of t. gondii in patients with ad compared to controls showed the possible impact of this parasite in ad, which may exacerbate symptoms, and this requires special attention of specialists and patient families. results the overall prevalence of t. gondii infection in patients with ad and the control group, using elisa assay, was obtained as 66.6% (58/87) and 56.32% (...

AI planning techniques are beginning to find use in a number of practical planning domains. However, the backward-chaining and partial-order-planning control strategies traditionally used in AI planning systems are not necessarily the best ones to use for practical planning problems. In this paper, we discuss some of the difficulties that can result from the use of backward chaining and partial...

background: crimean-congo hemorrhagic fever (cchf) is a feverous and hemorrhagic disease endemic in some parts of iran and caused by an arbovirus related to bunyaviridae family and nairovirusgenus. the main virus reser­voir in the nature is ticks, however small vertebrates and a wide range of domestic and wild animals are regarded as reservoir hosts. this study was conducted to determine the in...

The purpose of this paper is to describe a task and motion planning technique for designing a group control system in robotic construction works. This technique deals with hierarchical control of multiple robots and peripheral machinery in an automated construction work-cell. The technique consists of two phases: the task planing and the motion planning. The task planning phase illustrates the ...

background hiv/aids and tuberculosis (tb) are major contributors to the burden of disease in sub-saharan africa. the two diseases have been described as a harmful synergy as they are biologically and epidemiologically linked. control of tb/hiv co-infection is an integral and most challenging part of both national tb and national hiv control programmes, especially in contexts of instability wher...
