This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...

In this paper, we study virtual full-duplex (FD) buffer-aided relaying to recover the multiplexing loss of halfduplex (HD) relaying in a network with multiple buffer-aided relays, each of which has multiple antennas, through opportunistic relay selection and beamforming. The main idea of virtual FD buffer-aided relaying is that a source and a relay simultaneously transmit their own information ...

Early Programming Logic Control (PLC) were designed to replace relay logic systems. These PLCs were programmed in “Ladder Logic”, which strongly resembles a schematic diagram of relay logic. Programming logic control has several features like protection from the open area conditions such dust, heat and cold. PLC also has the ability to arrangement the inputs/outputs. It has low cost compared wi...

Programmable logic controller (PLC) can be programmed for various purposes, one of which is to design a fire extinguishing system, by assembling several components PLC, solenoid, springkle, powersupply ,adapter ,smokedetector, heatdetector, pilotlamp, pushbutton, relay, selector switch. the program settings detect smoke and high temperatures that occur in event fire. if sensor detects temperatu...

In order to improve the Voice over IP (VoIP) capacity of a Wireless Local Area Network (WLAN), we develop a relay-aided solution, which includes a relay-aided admission control scheme, a packet aggregation scheme, and a protocol for packet relay without sacrificing the voice quality. Basically, our admission control scheme utilizes relay stations to admit as many VoIP sessions as possible. When...

This paper describes a novel approach for combining Luby Transform (LT) codes and Network Coding (NC) in the context of PowerLine Communications (PLC) smart grid networks. Multihop transmissions of LT-encoded data on PLC networks are considered and algorithms to combine data at relay nodes are proposed. Without the need to decode and then re-encode the total received data stream, the relay node...

BACKGROUND THE SLEEP SEQUENCE: i) non-REM sleep, ii) REM sleep, and iii) wakefulness, is stable and widely preserved in mammals, but the underlying mechanisms are unknown. It has been shown that this sequence is disrupted by sudden REM sleep onset during active wakefulness (i.e., narcolepsy) in orexin-deficient mutant animals. Phospholipase C (PLC) mediates the signaling of numerous metabotropi...

—Low-Voltage Powerline Communications (LV PLC) is a favorable information exchange scheme for many Smart Grid (SG) applications. In this paper we focus on the broadband dual-hop relaying systems over LV PLC channel in which the relay node operates in either Amplify-and-Forward (AF) or Decode-and-Forward (DF) relaying protocol. The closed-form expressions of capacities for non-cooperative and c...

Elevator is an important transport medium in multi-storage building. With the development of better architecture technology, buildings are raising in height. Hence an elevator becomes an important medium of vertical transportation. There are several advantages of an elevator in the modern world. Hence more importance is given to the design of an elevator control system, which is easy for the ma...

In this work, we consider the use of buffer-aided relays, linear precoding techniques and multiple antennas for physical-layer security in wireless networks. We develop relay selection algorithms to improve the secrecy-rate performance of cooperative multi-user multiple-antenna wireless networks. In particular, we propose a novel finite buffer-aided relay selection algorithm that employs the ma...
