Abstract- Communication has become inevitably part of our day to day activities, in academic, business, banking, and other sectors. It has therefore become so important to implement good and efficient communication system. A reference point according to this research is the wireless sensor networking (WSN) system, and most important thing in communication is to be free from interference, attenu...

Unreliable failure detectors, proposed by Chandra and Toueg [2], are mechanisms that provide information about process failures. In [2], eight classes of failure detectors were defined, depending on how accurate this information is, and an algorithm implementing a failure detector of one of these classes in a partially synchronous system was presented. This algorithm is based on all-to-all comm...

This paper introduces our partially synchronous Θ-Model, which is essentially the well-known FLP model augmented with a bound Θ on the ratio between the maximum and minimum end-to-end delays of messages simultaneously in transit between correct processes. We show that the Θ-Model admits the implementation of a perfect failure detector, which allows to employ classic solutions for solving import...

BACKGROUND Rational antimicrobial therapy should provide maximum benefit to patients while minimizing the development of resistant microorganisms. OBJECTIVES The aim of this study was to investigate (i) which antimicrobial drugs were chosen by hospital doctors faced with two common infections [community-acquired pneumonia (CAP) and urinary tract infection (UTI)], (ii) whether these choices we...

With technological advances in the telecommunications sector, everyone around the world would like to be connected seamlessly anytime anywhere through the best network. Making a transition from one network to another and moving between heterogeneous networks is not the only problem that worried specialists, scientific and mobile operators; the concern of QoS is as important as the handoff, The ...

The broadband network gateway (BNG) play a crucial role in today’s networks, it hands all access network traffic (e.g DSL traffic), provisioning of such policies like rate limiter, tunneling and complex network management mechanisms that an Internet service providers (ISPs) needs to implement his services. These network devices are expensive, proprietary, limited and slow device upgrading, beco...

cystic fibrosis (cf) is an autosomal recessive disease, which affects many organs as it impairs chloride channel. this study was performed to evaluate growth status and its relationship with some laboratory indices such as cholesterol (chol), triglyceride (tg), albumin and total protein in children with cf referred to pediatrics center. this study was designed as a cross-sectional study in one ...

This study examined and presents an effective method for detection of failure of conductor bars in the winding of rotor of induction motor in low load conditions using neural networks of radial-base functions. The proposed method used Hilbert method to obtain the stator current signal push. The frequency and signal amplitude of the push stator were used as the input of the neural network and th...
