Sometimes called radio in the loop (RITL) or fixed-radio access (FRA), wireless local loop (WLL) is a system that connects subscribers to the public switched telephone network (PSTN) using radio signals as a substitute for copper for all or part of the connection between the subscriber and the switch. This includes cordless access systems, proprietary fixed radio access, and fixed cellular syst...

To combat the increasing significance of deployment and configuration costs, the concept of a self-deploying, self-configuring radio access network is discussed. It is proposed that the basic sciences of complex systems (cellular automata, game theory, ecology modeling) can be exploited to design algorithms for such a system. An example, taken from the field of cellular automata, is presented f...

Background: Radio-adaptive response and bystander effects are known phenomena occurring in cells following exposure to ionizing radiation (IR). In this study we examined possible radio-adaptation of lymphocytes following bystander effects induced by CHO-K1 cells. Materials and Methods: Whole blood and CHO-K1 cells were cultured in RPMI-1640 complete medium. Cells were separately irradiated with...

exposure to high dosages of sulfur mustard (sm) can cause bone marrow depression, immune system suppression, impairment of the immune functions, and eventually results in diseases due to secondary immune disorders. in this article, we have studied the effects of this poison on iranian veterans by analysis of related published studies. in a systematic search, the effects of sm gas on iranian vic...

In this paper, we present a multiagent algorithm for the frequency assignment problem in cellular radio networks. The algorithm, that has been successfully applied to GSM networks, efficiently assigns frequencies to each radio cell satisfying the constraints given by a compatibility matrix.

Adaptive power control scheme based on the optimization of transmitter power and receiver filter coefficients is shown. The scheme is mapped to control logic, digital filter and adaptive amplifier. Accurate power control can reduce the interference in both Global System Mobile (GSM) and CDMA system. When the mobile is close to the base station, it can use lower power since the signal loss is sm...

cellular manufacturing system (cms) is highly important in modern manufacturing methods. given the ever increasing market competition in terms of time and cost of manufacturing, we need models to decrease the cost and time of manufacturing. in this study, cms is considered in condition of dynamic demand in each period. the model is developed for facing dynamic demand that increases the cost of ...

In this paper, we exploit one of the fastest growing techniques of Soft Computing, i.e. Artificial Neural Networks (ANNs) for obtaining various performance measures of a cellular radio system. A prioritized channel scheme with subrating is considered in which a fixed number of channels are reserved for handoff calls and in case of heavy traffic, these reserved channels are subrated into two cha...
