Distributed generation (DG) sources are becoming more prominent in distribution systems due to the incremental demands for electrical energy. Locations and capacities of DG sources have great impacts on the system losses in a distribution network. This paper presents a study aimed for optimally determining the size and location of distributed generation units in distribution systems with differ...

increasing of the distribution efficiency is one of the most objectives of an integrated logistic system developed as a new management philosophy in the past few decades. the problem is examind in two parts: facilities location problem (flp) for long policies and vehicle routing problem (vrp) to meet the customer demand. these two components can be solved separately; however, this solution may ...

Today, the presence of disturbing loads in low, medium and also directly in high voltage networks is producing a growing presence of harmonics and unbalance in transmission levels. Economic reasons difficult the installation of harmonic measurement devices in all the buses of the system. Instead, it would be possible to install harmonic measurement equipment in selected buses, in a fraction of ...

Commercial applications for the location of subscribers of wireless services continue to expand. Consequently, finding the CramerRao bound (CRB), which serves as an optimality criterion for the location estimation problem, is of interest. In this article, we derive the CRB for the estimation of channel parameters and mobile position in an asynchronous direct sequence code division multiple acce...

Collaborative beamforming (CB) in wireless sensor networks (WSNs) promises improvement of communication performance and energy efficiency. The random distribution sensor nodes location within WSNs can introduce random beampattern mostly in the sidelobe region. In addition, higher energy consumption can occur as the randomness permits the generation of high peaks in radiation beampattern perform...

The paper proposes methodologies to convert discrete spatial data into continuous functions in a metric space so that the continuous approximation (CA) optimization framework can be applied to a general class of discrete facility location problems. We integrated a range of computational geometry methods to estimate the optimal system costs and the optimal number of facilities, and then develope...

In this paper*, the performance of a distributed mobility management scheme, the Randomized Database Group (RDG), for mobile ad hoc networks is presented. In this scheme, databases are used to store the location of the network nodes and to manage the mobility of nodes. When a mobile's location changes, a number of randomly selected databases are updated. When a mobile's location is needed, such...
