An innovative method of obtaining the weights for a Finite Impulse Response (FIR) notch filter using the Eigen-approach is proposed. The Eigen-approach was used to identify the frequencies of the source signals by determining the eigenvector corresponding to the minimum eigenvalue of the autocorrelation matrix. The FIR notch filter was constructed...

Background The widespread use of social media applications generated a problematic behavior of excessive and inappropriate use that has been associated with mental health problems. Available data assessed this behavior using different surrogate markers in certain university majors. This study aims to assess the effect of this behavior on academic p...

An Eigen-approach method using a two-element antenna array for estimating the frequencies of source signals jointly with the angle-of-arrival (AOA) was proposed. The eigenvector corresponding to the minimum eigenvalue of the autocorrelation matrix was used initially to find the frequencies of the source signals. By moving the roots produced from th...

An accurate method for estimating the direction-of-arrival (DOA) jointly with the frequencies of an unknown number of source signals is proposed using the Eigen-approach. Using the minimum eigenvalues of the autocorrelation matrices produces both the DOA and the corresponding frequencies. By moving the roots produced from the eigenvector one-by-one...

Because global positioning system (GPS) users receive a very low power signal outdoors, it is difficult for users to find their location indoors using GPS. Cooperative localization attempts to solve this problem by using information from surrounding users in an ad hoc scenario. Unfortunately this makes the localization system vulnerable to spoofing...

This research deals with an energy efficient network for military mobile base station placement. The proposed method is based on minimizing the energy loss of military communication networks where the base station is moving along a preset path and the users are constantly moving in an independent speed and direction. It takes into account the free...

Many papers have been proposed in order to increase the wireless sensor networks performance; This kind of network has limited resources, where the energy in each sensor came from a small battery that sometime is hard to be replaced or recharged. Transmission energy is the most concern part where the higher energy consumption takes place. Clustered...

Due to high restrictions in sensor network, where the resources are limited, clustering protocols for routing organization have been proposed in much research for increasing system throughput, decreasing system delay and saving energy. Even these algorithms have proposed some levels of security, but because of their dynamic nature of communication,...

Many algorithms and techniques were proposed to increase the efficiency of Sensor Networks. Due to high restrictions of this kind of networks, where the resources are limited, many factors may affect its work. Theses factors are: System throughput, system delay, and energy. Clustering protocols have been propose to decrease system throughput and sy...

The use of sensor networks is increasing day by day; which offer more research topics to be discuss and modified; one of these topics is the power consumption that has to be reduced as possible, where the resources are limited; another topic is the security level that should be offer by such kind of networks. Clustered networks have been proposed i...
