Publish-subscribe based middleware for heterogeneous critical infrastructure systems communication.
(2014-07-01)
Critical Infrastructures (CIs) are physical assets and organizations responsible for the production and distribution of society’s vital goods and services. The increasing interconnection of CIs has resulted in interdependencies ...
Joint channel pairing and power allocation optimization in two-way multichannel relaying.
(2014-08-01)
We consider two-way amplify-and-forward relaying in a multichannel system with two
end nodes and a single relay, using a two-slot multi-access broadcast (MABC) as well as
time-division broadcast (TDBC) relaying strategies. ...
Determining fuzzy link quality membership functions in wireless sensor networks
(2014-04-01)
Wireless Sensor Network routing protocols rely on the estimation of the quality of the links between nodes to determine a suitable path from the data source nodes to a data-collecting node. Several link estimators have ...
Learning image enhancement and object localization using evolutionary algorithms
(2014-03-01)
Imaging and image processing have been used in variety of applications, such as medical,
astronomy, forensic, and industry. Numerous techniques have been proposed to solve
speci c problems faced in particular applications ...
Multi-antenna relay network beamforming design for multiuser peer-to-peer communications.
(2014-08-01)
In this work, we consider a multi-user peer-to-peer relay network with multiple multiantenna
relays which employ amplify-and-forward relaying protocol. Assuming distributed
relay beamforming strategy, we investigate the ...
Development, analysis and performance assessment of net zero energy house systems.
(2014-08-01)
Net zero energy buildings have captured the attention of many researchers and governments due to high energy consumption by traditional buildings. The design stage of a net zero energy house is the most crucial and cost ...
Advances in parallel robotics for flexible and reconfigurable manufacturing
(2014-04-01)
Parallel robotic manipulators are a specific type of robot that has multiple
limbs which are ultimately connected to a moving body. Within
this regime, there are several sub-classes of robots characterized by
certain ...
Distributed policy-based management framework for wireless sensor networks.
(2014-06-01)
Policy-Based Management Systems (PBMS) are becoming a critical component of any information technology environment, due to their ability to abstract hardware complexity from their users. Policy-based systems exist in such ...
Asynchronous bi-directional relay-assisted communication networks
(2014-02-01)
We consider an asynchronous bi-directional relay network, consisting of two singleantenna
transceivers and multiple single-antenna relays, where the transceiver-relay
paths are subject to different relaying and/or ...
Analysis, assessment and optimization of integrated solar energy systems for multigeneration
(2014-12-01)
The extensive usage of fossil fuel in most of human activities has led to the undesirable effects on the environment starting from global warming and greenhouse effects to the climate changes, acid rain and others. Renewable ...
