This report describes the design, construction and test results of an inductively coupled battery charger for robot power supplies. The system should be capable of charging several robot batteries at once from a contactless charging station. The charger should be capable of providing different charging conditions to several different kinds of battery at once. The system should be capable of cha...

| In cellular wireless communication systems, transmitted power is regulated to provide each user an acceptable connection while limiting the interference seen by other users. Previous work has focused on maximizing the minimum carrier to interference ratio (CIR) or attaining a common CIR over all radio links. However, previous work has assumed the assignment of mobiles to base stations is know...

Base stations represent the main contributor to the energy consumption of a mobile cellular network. Since traffic load in mobile networks significantly varies during a working or weekend day, it is important to quantify the influence of these variations on the base station power consumption. Therefore, this paper investigates changes in the instantaneous power consumption of GSM (Global System...

Digital tuning systems are fast replacing the conventional mechanical systems in AM/FM and television receivers. The desirability of the digital approach is mainly due to the following features: Y Precise tuning of station frequencies Y Exact digital frequency display Y Keyboard entry of desired frequency Y Virtually unlimited station memory Y Up/down scanning through the band Y Station ‘‘searc...

the paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. some mathematical vector models were obtained for control system multicriterion quality indices with due ...

In this paper, we propose how to control the uplink transmit power of a mobile station (MS) during soft handoff in order to reduce the error probability of downlink transmit power control command bit without macro diversity gain at the base station controller (BSC). The uplink transmit power control is based on uplink transmit power control commands from all base stations (BS’s) belonging to th...
