It is well established that the main intrinsic electrophysiological properties of thalamocortical relay cells, production of a low threshold burst upon release from hyperpolarized potential and production of a train of single spikes following stimulation from depolarized potentials, can be readily modelled using a single compartment. There is, however, another less well explored intrinsic elect...

In this paper, power efficiency (PE) of a relay interference channel including multiple transmitter nodes, multiple relay nodes and multiple destination is investigated. It is assumed that the destination and transmitter nodes are equipped with a few number of antennas but the relay nodes have a large number of antennas. Amplify-forward and decode-forward schemes by using MRT/MRC and ZF process...

This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...

This paper presents a new fast-acting backup protection strategy for future hybrid ac-dc distribution networks. By examining the impedance measured by distance relay measuring from “ac-side” of network, unique characteristic is established faults occurring on “dc-side” an embedded medium-voltage dc (MVDC) link, interconnecting two 33 kV network sections. Based identified characteristic, appropr...

the ability of smartphone technology to document static microscopy images has been well documented and is gaining widespread use in ophthalmology, where slit-lamp biomicroscopy is frequently utilized. however, little has been described regarding the use of smartphone technology to relay video of tissue microscopy results to patients, particularly when a tissue sample integrates motility of orga...

From practical and theoretical viewpoints, performance analysis of communication systems by using information-theoretic results is important. In this paper, based on our previous work on Multiple Access Channel (MAC) and Multiple Access Relay Channel (MARC), we analyze the impact of a relay on the fundamental wireless communications concept, i.e., coverage region of MARC, as a basic model for u...

The most important characteristic of RFID-based electronic voting system compared to traditional voting system is that votes in the electronic system are as contactless smart cards in place of paper ballots. For casting ballots, voters use a computer terminal to write their choices (their chosen candidates) into contactless smart cards and then put the smart card inside the box. The most import...

In this channel,we study rate region of a Gaussian two-way diamond channel which operates in half-duplex mode. In this channel, two transceiver (TR) nodes exchange their messages with the help of two relay nodes. We consider a special case of the Gaussian two-way diamond channels which is called Compute-and-Forward Multiple Access Channel (CF-MAC). In the CF-MAC, the TR nodes transmit their mes...

abstract—in this paper, the problem of secure transmission in two-hop amplify-and-forward (af) systems with an untrusted relay is investigated. to prevent the untrusted relay from intercepting the source message and to achieve positive secrecy rate, the destination-based cooperative jamming (dbcj) technique is used. in this method the destination sends an intended jamming signal to the relay. t...

This paper presents a novel methodology for testing modern protective relays. Its primary focus is a distance relay. The proposed methodology consists of both design and application testing. Design testing is aimed at assessing predictive relay behavior by measuring its real operating characteristic. Application testing has the form of transient testing and it is aimed at assessing the random a...
