Lifetime maximization for greedy selective relay strategies
(2009 , Conference Paper)
In this paper we propose a new algorithm for selective relay strategies with Amplify-and-Forward (AF) relays which improves the relay network lifetime. The lifetime of the relay network is defined as the maximum number of ...
Lifetime maximization with predictive power management in selective relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2009 , Conference Paper)
A diversity scheme which exploits the existence of a source-destination path to improve the lifetime and outage probability of a wireless selective relay network with Amplifyand-Forward (AF) relays is proposed and studied. ...
Novel linearizer for tangent/cotangent converter
(
IEEE
, 2009 , Conference Paper)
Resolvers and other types of sinusoidal encoders provide electrical signals whose amplitudes are related to the sine and cosine of the mechanical shaft angle ¿ over the full 360° range. The tangent/cotangent converter, ...
A new closed-loop converter for sinusoidal encoders - Preliminary results
(
IEEE
, 2009 , Conference Paper)
Sinusoidal position transducers provide accurate and reliable representation of the mechanical position of their shafts. The sine/cosine transducers signals may be used in open loop or closed loop arrangements for the ...
Data Mining, Reasoning and Incremental Information Retrieval through Non Enlargeable Rectangular Relation Coverage
(
Springer Berlin / Heidelberg
, 2009 , Conference Paper)
Association rules extraction from a binary relation as well as reasoning and information retrieval are generally based on the initial representation of the binary relation as an adjacency matrix. This presents some ...
An assistive computerized system for children with intellectual and learning disabilities
(
Springer
, 2009 , Conference Paper)
This work proposes an assistive computerized system using the Arabic language for children with intellectual and learning disabilities (ILD) who are resident at Shafallah Center in Doha, Qatar. The system is flexible and ...
Towards an electronic voting system for the state of Qatar
(
IEEE
, 2009 , Conference Paper)
In this paper we propose an electronic voting system for the state of Qatar. The system allows Qataris people to vote online from their preferred locations, (homes or offices) without the need to move physically to the ...
Wireless application deploying cell broadcast, and bulk SMS/MMS
(
International Business Information Management Association, IBIMA
, 2009 , Conference Paper)
Cell broadcast is a mobile technology that allows messages to be broadcast to all mobile handsets and similar devices within a designated geographical area. The broadcast range can be varied, from a single cell to the ...
SecCom: A prototype for integrating security-aware components
(
Springer Verlag
, 2009 , Conference Paper)
This paper addresses information security from systems development point of view. This paper presents a prototype demonstrating how security-aware software components can be composed with other remote objects in terms of ...
