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 ...
Rapidly Varying Sparse Channel Tracking with Hybrid Kalman-OMP Algorithm
(Springer, 2019)
It is expected from future communication standards that channel estimation algorithms should be able to operate over very fast varying frequency selective channel models. Therefore in this study autoregressive (AR) modeled ...
A Computerized Recognition System for the Home-Based Physiotherapy Exercises Using an RGBD Camera
(IEEE, 2014)
Computerized recognition of the home based physiotherapy exercises has many benefits and it has attracted considerable interest among the computer vision community. However most methods in the literature view this task as ...
Information theoretical performance limits of single-carrier underwater acoustic systems
(Inst Engineering Technology-IET, 2014)
In this study the authors investigate the information theoretical limits on the performance of point-to-point single-carrier acoustic systems over frequency-selective underwater channels with intersymbol interference. Under ...
Exploiting heterogeneous parallelism with the Heterogeneous Programming Library
(Academic Press Inc Elsevier Science, 2013)
While recognition of the advantages of heterogeneous computing is steadily growing the issues of programmability and portability hinder its exploitation. The introduction of the OpenCL standard was a major step forward in ...
Developing adaptive multi-device applications with the Heterogeneous Programming Library
(Springer, 2015)
The usage of heterogeneous devices presents two main problems. One is their complex programming a problem that grows when multiple devices are used. The second issue is that even if the codes for these devices can be ...
Joint Channel Estimation and Symbol Detection for OFDM Systems in Rapidly Time-Varying Sparse Multipath Channels
(Springer, 2015)
In this paper we propose a space-alternating generalized expectation maximization (SAGE) based joint channel estimation and data detection algorithm in compressive sensing (CS) framework for orthogonal frequency-division ...
New Infinite Families of 2-Edge-Balanced Graphs
(Wiley-Blackwell, 2014)
A graph G of order n is called t-edge-balanced if G satisfies the property that there exists a positive for which every graph of order n and size t is contained in exactly distinct subgraphs of Kn isomorphic to G. We call ...
