This extensive growth of cellular telephone use around the world is due to the tremendous and rapid advances in the field of wireless communications. Moreover, the societal pressures for increased efficiency, and an improved sense of safety associated with the availability of a cell phone contributed to a dramatic increase in cellular telephone use by drivers in vehicles. It is estimated that m...

We conducted a survey of over 5,000 telephone users who were customers of one large cellular telephone company covering four major geographical areas. Our primary goal was to assess the utility of ascertaining information on telephone use and type from telephone company records. We compared information from 3,949 respondents with corresponding data from company billing records. We found that 48...

the cellular automata method has been used to simulate the pattern formation of the schlögl model as a bistable reaction-diffusion system. both microscopic and macroscopic cellular automata approaches have been considered and two different methods for obtaining the probabilities in the microscopic approach have been mentioned. the results show the tendency of the system towards the more stable ...

Little is known about the comparability of postal and telephone survey modes in epidemiology. A cross-sectional, population-based study (n = 25,000) of lung disease was performed in 1998-1999 in two regions of Norway. Initial surveying was done by postal questionnaire. A 1% random sample (n = 171) of previous postal responders were resurveyed by telephone or cellular contact. The response rate ...

in order to implement the cellular manufacturing system in practice, some essential factors should be taken into account. in this paper, a new mathematical model for cellular manufacturing system considering different production factors including alternative process routings and machine reliability with stochastic arrival and service times in a dynamic environment is proposed. also because of t...

production planning is performed through diverse methods according to the type of the system it is structured upon. one of the most important steps before production planning is to determine which system best fits the firm, and how the facilities should be designed. both job-shop and group-technology systems have their own pros and cons, each of which is suitable to a specific kind of factory. ...
