A Gathering Process in Artin Braid Groups
In this paper we construct a gathering process by the means of which we obtain new normal forms in braid groups. The new normal forms generalise Artin-Markoff normal forms and possess an extremely natural geometric description. In the two last sections of the paper we discuss the implementation of the introduced gathering process and the questions that arose in our work. This discussion leads u...
متن کاملA Cellular Automaton Based Algorithm for Mobile Sensor Gathering
In this paper we proposed a Cellular Automaton based local algorithm to solve the autonomously sensor gathering problem in Mobile Wireless Sensor Networks (MWSN). In this problem initially the connected mobile sensors deployed in the network and goal is gather all sensors into one location. The sensors decide to move only based on their local information. Cellular Automaton (CA) as dynamical sy...

15 صفحه اولProblems and Benefits of Requirements Gathering With Focus Groups: A Case Study
Focus group interviews are considered as a rather weak, nonquantitative method of assessing user needs, ideas, and reactions in an early stage of the interface design process (Nielsen, 1993). Given this fact, it is relevant to reflect the practical use of focus groups step by step to determine their real strengths and limitations. In this article, we share our experience of planning, running, a...
