Sparse channel estimation for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE Computer Society, 2014)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ...
Max-pivot routing for opportunistic networks
(2013)
Opportunistic networks are challenging types of networks where network connections are imminent. Network topologies are dynamic and can rapidly change. A path between a source node and a destination node may or may not ...
A non-communicating multi-robot system with switchable formations
(2013)
We consider connected navigation of autonomous mobile robots with transitions in the group formation. The robots navigate using simple local steering rules without requiring explicit communication among themselves. The ...
A monitoring system for home-based physiotherapy exercises
(2013)
This paper describes a robust low-cost vision based monitoring system for home-based physical therapy exercises (HPTE). Our system contains two different modules. The first module achieves exercise recognition by building ...
A re-configuring sliding-mode controller with a ustable robustness
(Pergamon-Elsevier Science Ltd, 2004)
In this paper a controller design method for underwater vehicles is presented which is based on re-configuration of a sliding-mode controller in case of disturbances caused by shallow water conditions. The disturbance ...
Optimal input design for the detection of changes towards unknown hypotheses
(Taylor & Francis Ltd, 2004)
The effects of auxiliary input signals on detecting changes in ARMAX processes via statistical tests are discussed. Two extensions to the Cumulative Sum Test are considered. The first is applicable when the direction of ...
SiPAN: simultaneous prediction and alignment of protein-protein interaction networks
(Oxford University Press, 2015)
Motivation: Network prediction as applied to protein-protein interaction (PPI) networks has received considerable attention within the last decade. Because of the limitations of experimental techniques for interaction ...
Three-fast-searchable graphs
(Elsevier Science Bv, 2013)
In the edge searching problem searchers move from vertex to vertex in a graph to capture an invisible fast intruder that may occupy either vertices or edges. Fast searching is a monotonic internal model in which at every ...
SPINAL: scalable protein interaction network alignment
(Oxford University Press, 2013)
Motivation: Given protein-protein interaction (PPI) networks of a pair of species a pairwise global alignment corresponds to a one-to-one mapping between their proteins. Based on the presupposition that such a mapping ...
Accelerating Brain Simulations on Graphical Processing Units
(IEEE, 2015)
NEural Simulation Tool(NEST) is a large scale spiking neuronal network simulator of the brain. In this work we present a CUDA(R) implementation of NEST. We were able to gain a speedup of factor 20 for the computational ...
