Tracking and constraining authorization provenance
(
Springer Berlin Heidelberg
, 2012 , Conference Paper)
Authorization provenance concerns how an authorization is derived. It appears important to define authorization provenance to (1) analyze policy bases, (2) defend against a class of attacks, and (3) audit authorizations. ...
Assessment of Climate Adaptation of Youth Club in Tozeur, South of Tunisia
(
Elsevier Ltd
, 2012 , Conference Paper)
Impact of users on thermal behaviour of a building and a building's impact on the use of different spaces are two aspects that are subject of post occupancy evaluation of the present paper. The building was designed according ...
Multiple-runway aircraft sequencing problems using mixed-integer programming
(
Institute of Industrial Engineers
, 2012 , Conference Paper)
We examine aircraft sequencing problems over multiple runways, under mixed mode operations, with the objective of minimizing the total weighted tardiness of aircraft landings and departures. A mixed-integer programming ...
On critical point avoidance among mobile terminals in healthcare monitoring applications: Saving lives through reliable communication software
(
IEEE
, 2012 , Conference Paper)
The advances in Microelectromechanical systems (MEMS), battery life, low powered communication standards, more capable processing units, and hybrid communication have cemented the use of mobile Wireless Body Area Networks ...
Forced spectrum access termination probability analysis under restricted channel handoff
(2012 , Conference Paper)
Most existing works on cognitive radio networks assume that cognitive (or secondary) users are capable of switching/jumping to any available channel, regardless of the frequency gap between the target and the current ...
Improving the classification of newborn EEG time-frequency representations using a combined time-frequency signal and image approach
(2012 , Conference Paper)
This paper presents new time-frequency (T-F) features to improve the classification of non-stationary signals such as EEG signals. Previous methods were based only on signal features that were derived from the instantaneous ...
Generalised phase synchrony within multivariate signals: An emerging concept in time-frequency analysis
(2012 , Conference Paper)
This paper introduces the notion of the instantaneous frequency (IF) based generalized phase synchrony in time-frequency analysis based on the concept of cointegration. This phase synchrony is then quantified by investigating ...
Towards understanding the effects of climatic and environmental factors on solar PV performance in arid desert regions (Qatar) for various PV technologies
(
IEEE
, 2012 , Conference Paper)
The sensitivity of various solar photovoltaic technologies to dust, temperature and relative humidity is investigated for Qatar's environment. Results obtained show that mono-crystalline PVs have efficiencies as high as ...
Area spectral efficiency of cooperative network with DF and AF relaying
(
IEEE
, 2012 , Conference Paper)
Most performance metrics for cooperative networks focus on the qualification of either spectrum efficiency or link reliability, without considering the spatial effect of radio transmission. Area spectral efficiency (ASE) ...
An improved SVPWM method for multilevel inverters
(
IEEE
, 2012 , Conference Paper)
This paper proposes a new general Space Vector PWM (SVPWM) method for Multi-Level Inverters (MLI) based on a generalization of dwell-times calculation. The presented scheme is developed for Cascaded H-Bridge (CHB) inverter. ...
