چکیده
INTRODUCTION The cumulative dose of radio-frequency electromagnetic field exposure from cellular phones during usage in a network is a function of the SAR strength and distribution (SARdistr(f)) at the maximum power control (PWC) level (PWCmax(f)), the average PWC level (PWCavg(f)) depending on the corresponding transmission mode (communication system and frequency (f)), and the duration of the exposure (t). The total dose for a phone continuously operated at the same position at the head in a certain communication system at frequency (f) can be assessed as follows:

Load-Frequency Control: a GA based Bayesian Networks Multi-agent System
Bayesian Networks (BN) provides a robust probabilistic method of reasoning under uncertainty. They have been successfully applied in a variety of real-world tasks but they have received little attention in the area of load-frequency control (LFC). In practice, LFC systems use proportional-integral controllers. However since these controllers are designed using a linear model, the nonlinearities...
متن کاملJoint Allocation of Computational and Communication Resources to Improve Energy Efficiency in Cellular Networks
Mobile cloud computing (MCC) is a new technology that has been developed to overcome the restrictions of smart mobile devices (e.g. battery, processing power, storage capacity, etc.) to send a part of the program (with complex computing) to the cloud server (CS). In this paper, we study a multi-cell with multi-input and multi-output (MIMO) system in which the cell-interior users request service...
متن کاملA Robust Discrete FuzzyP+FuzzyI+FuzzyD Load Frequency Controller for Multi-Source Power System in Restructuring Environment
In this paper a fuzzy logic (FL) based load frequency controller (LFC) called discrete FuzzyP+FuzzyI+FuzzyD (FP+FI+FD) is proposed to ensure the stability of a multi-source power system in restructured environment. The whale optimization algorithm (WOA) is used for optimum designing the proposed control strategy to reduce fuzzy system effort and achieve the best performance of LFC task. Further...
متن کاملComparison of Optimized PSS Using Three Different Methods for Single and Multi-Machines Systems
Oscillations of power systems cause instability in power networks. Power system stabilizer (PSS) is used as a conventional method to damp these oscillations . Finding the optimized gain of PSS is one of the major problems in power system stability issue. In this paper, single machine connected to an infinite bus and 10-machines 39-bus network are considered for study. it's shown that finding th...
متن کاملAsymptotic Close to Optimal Resource Allocation in Centralized Multi-band Wireless Networks
This paper concerns sub-channel allocation in multi-user wireless networks with a view to increasing the network throughput. It is assumed there are some sub-channels to be equally divided among active links, such that the total sum rate increases, where it is assumed each link is subject to a maximum transmit power constraint. This problem is found to be a non-convex optimization problem and i...
