This paper proposes a minimummean-square-error bi-directional amplify-and-forward (MMSEBAF) relaying protocol for multi-hop wireless networks employing multi-antenna relays. MMSEBAF is a two-phase relaying protocol which allows for two sources to exchange independent messages via a relay node equiped with multiple antennas. The latter performs a joint linear MMSE filtering of the received signa...

in this paper two different rateless transmissionschemes are developed. in the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...

Power system protection in electrical power engineering aims at eliminating a faulted part in an electric network from an otherwise healthy power system. Protection coordination involves a process of best timing any faulted currents so as to reduce the extension of outage areas to a minimum after a fault clearance. In the paper, innovative protection methods and devices widely based on computer...

Targeting abnormal calcium (Ca) handling in ventricular cardiomyocytes emerged as a new paradigm for human heart failure (HF) therapy. Cardiomyocytes come with an extensive Ca signaling toolkit consisting of various Ca transporters, Ca channels, Ca buffer, and sensor proteins. Organized into self-contained signaling modules in which Ca signaling functions within highly localized environments, t...

The aim of the relay coordination is that protection systems detect and isolate the faulted part as fast and selective as possible. On the other hand, in order to reduce the fault clearing time, distance protection relays are usually equipped with pilot protection schemes. Such schemes can be considered in the distance and directional overcurrent relays (D&DOCRs) coordination to achieve faster ...

The hardware necessary for the electro-optic study of conducting polyelectrolyte solutions is frequently not commercially available or financially practical. The designs of an electrical rectangular pulse switch and polarity-reversing relay switch capable of producing 3 kV 5 A direct current pulses lasting longer than 100 ms are presented. As an example of the operation of this equipment, the e...

In this paper we present real-time application for detecting, extracting and automatic classification of transient disturbances in electric power network. Proposed method was implemented on Texas Instruments C6713 DSK toolkit and tested with both laboratory-generated and real-world power network signals with good results. For each detected transient a set of parameters is evaluated including th...

1  Abstract-This paper was written by a Working Group of the IEEE Power System Relay Committee to provide guidance to the industry to better coordinate generator protection with generator control. The paper discusses specific calculation methods that can be used to insure generator protection and excitation system control are fully coordinated. It also specifically addresses the coordination o...
