A scheme for coordinated secondary voltage control for systems with multiple VAr reserves

This paper presents a voltage control scheme for coordinating reactive power reserves, inspired by the concept of multi-agent system. Similar to an agent, the proposed controller takes on assigned tasks itself and contacts neighbors for support when needed. The control structure incorporates not only controllable VAr sources but also switched capacitor banks, resulting in increased […]

Magnetic interaction and electronic transport in La0.4Bi0.6Mn0.5Ti0.5O3manganite

In recent years perovskite type manganites having general formula ABO3 have attracted significant deliberation because of their importance both for potential magneto-electronic applications and fundamental research in condensed matter physics. The properties of these materials such as magnetoresistance, metal-insulator transition, charge, magnetic ordering, etc., have attracted significant attention [1]. The substitution of divalent or other trivalent […]

From Demand Response in Smart Grid Toward Integrated Demand Response in Smart Energy Hub

The proliferation of technologies such as combine heat and power systems has accelerated the integration of energy resources in energy hubs. Besides, the advances in smart grid technologies motivate the electricity utility companies toward developing demand response (DR) programs to influence the electricity usage behavior of the customers. In this paper, we modify the conventional […]

A Novel 2D Urban Map Search Framework Based on Attributed Graph Matching

This paper presents a novel framework for urban map search. The search capabilities of the existing GIS systems are restricted to text-based search, neglecting significant topological and semantic information. We propose a framework that aims to extend the search capabilities by offering sketch-based search. Initially, the urban maps are processed in an offline step in […]

Circuit design perspectives for Ge FinFET at 10nm and beyond

In this paper we study the circuit design implications of Ge vs. Si PMOS FinFETs at the 10 and 7nm nodes, using TCAD calibrated statistical compact models and the ARM predictive benchmarking flow. The ARM predictive flow incorporates advanced-node-relevant layouts, design rules, parasitic RC extraction and wire-loading. We present the first comprehensive simulation study evaluating […]

Group RNTI for Multi-Users Multiplexing Radio Voice Transmission for Enhancing Voice Capacity over LTE in PMR Context

The Multi-users Multiplexing Radio Voice Transmission method [1] is used for reducing the data overhead of Voice over Long Term Evolution (VoLTE) in the Professional Mobile Radio (PMR) context. In the Multi-users Multiplexing Radio Voice Transmission method, voice packets from different users having the same Modulation and Coding Scheme (MCS) can be clustered into one […]

Coverage enhancement techniques for machine-to-machine communications over LTE

The tremendous growth of machine-tomachine (M2M) applications has been a great attractor to cellularnetwork operators to provide machine-type communication services. One of the important challenges for cellular systems supporting M2M terminals is coverage, because terminals can be located in spaces in buildings and structures suffering from significant penetration losses. Since these terminals are also often stationary, […]

HomePlug green PHY for the LVDC PLC concept: Applicability study

It has been shown that high-frequency (HF) band power line communication (PLC), that is, the HomePlug 1.0 specification, is feasible for a low-voltage direct current (LVDC) smart grid (SG) system, where power electronics and low-voltage DC are applied to the electricity distribution. In this paper, the applicability of the latest HomePlug specification, Green PHY (GP), […]

A Predictive Resource Allocation Algorithm in the LTE Uplink for Event Based M2M Applications

Some M2M applications such as event monitoring involve a group of devices in a vicinity that act in a co-ordinated manner. An LTE network can exploit the correlated traffic characteristics of such devices by proactively assigning resources to devices based upon the activity of neighboring devices in the same group. This can reduce latency compared […]

Network coding based mechanism to provide reliable multimedia content distribution in harsh environments

Multimedia services distribution is very dependent on the quality of the communications link. Due to the nature of the related services, these are usually very sensitive to packet loss, delay and jitter, and hence service quality is immediately worsen in harsh scenarios. This paper proposes an OSI-Layer2 cooperative link layer scheme (known as GalaReS) that […]
