Force-Directed Approaches to Sensor Localization
(Association for Computing Machinery, 2010)As the number of applications of sensor networks increases so does the interest in sensor network localization that is in recovering the correct position of each node in a network of sensors from partial connectivity ... -
A framework for combined recognition of actions and objects
(Springer-Verlag Berlin, 2012)This paper proposes a novel approach to recognize actions and objects within the context of each other. Assuming that the different actions involve different objects in image sequences and there is one-to-one relation ... -
Frequency selective fading channel estimation in OFDM systems using KL expansion
(2005)This paper proposes a computationally efficient linear minimum mean square error (MMSE) channel estimation algorithm based on KL series expansion for OFDM systems. Based on such expansion no matrix inversion is required ... -
Fully Decentralized and Collaborative Multilateration Primitives for Uniquely Localizing WSNs
(Springer International Publishing Ag, 2010)We provide primitives for uniquely localizing WSN nodes. The goal is to maximize the number of uniquely localized nodes assuming a fully decentralized model of computation. Each node constructs a cluster of its own and ... -
Fully decentralized, collaborative multilateration primitives for uniquely localizing WSNs
(Springer, 2009)We provide primitives for uniquely localizing WSN nodes. The goal is to maximize the number of uniquely localized nodes assuming a fully decentralized model of computation. Each node constructs a cluster of its own and ... -
GPU Accelerated Molecular Docking Simulation with Genetic Algorithms
(Springer International Publishing Ag, 2016)Receptor-Ligand Molecular Docking is a very computationally expensive process used to predict possible drug candidates for many diseases. A faster docking technique would help life scientists to discover better therapeutics ... -
Growth kinetics of MPS-capped CdS quantum dots in self-assembled thin films
(Springer, 2012)For this study we prepared colloidal CdS quantum dots using 3-mercaptopropyltrimethoxysilane as capping agent. Colloidal CdS quantum dots were directly deposited on glass substrates by a spin-coating process. Coated ... -
Hybrid MPI plus UPC parallel programming paradigm on an SMP cluster
(TUBITAK Scientific & Technical Research Council Turkey, 2012)The symmetric multiprocessing (SMP) cluster system which consists of shared memory nodes with several multicore central processing units connected to a high-speed network to form a distributed memory system is the most ... -
Implementation of a SDN (Software defined network)
(International Institute of Informatics and Systemics IIIS, 2014)Improving resource efficiency enhancing network security and achieving simpler network management have become the main goals for networking in the previous years. To accomplish these ideas an efficient routing traffic ... -
Importance of Regional Differences in Brain Throughout Aging for Down Syndrome
(Association for Computing Machinery, 2018)Down syndrome (DS) which affects approximately one in 700 live births is caused by an extra copy of the long arm of human chromosome 21 (HSA21). Statistical analysis has been done for understanding the protein expression ... -
Improvement of indoor positioning accuracy of ultra-wide band sensors by using big bang-big crunch optimization method
(Pamukkale Univ, 2018)Ultra-wide Band technology is an emerging technology that offers successful solutions in many indoor positioning systems and performs better than other methods. In this study an indoor positioning system using Ultra-wide ... -
Improving Energy-Efficiency of WSNs through LEFCA
(Sage Publications Inc, 2016)Wireless sensor networks (WSNs) have become an important part of our lives as they can be used in vast application areas from disaster relief to health care. As a consequence the life span and the energy consumption of a ... -
Improving OpenCL programmability with the Heterogeneous Programming Library
(Elsevier Science Bv, 2015)The use of heterogeneous devices is becoming increasingly widespread. Their main drawback is their low programmability due to the large amount of details that must be handled. Another important problem is the reduced code ... -
Improving performances of suboptimal greedy iterative biclustering heuristics via localization
(Oxford University Press, 2010)Motivation: Biclustering gene expression data is the problem of extracting submatrices of genes and conditions exhibiting significant correlation across both the rows and the columns of a data matrix of expression values. ... -
In silico identification of critical proteins associated with learning process and immune system for Down syndrome
(Public Library Science, 2019)Understanding expression levels of proteins and their interactions is a key factor to diagnose and explain the Down syndrome which can be considered as the most prevalent reason of intellectual disability in human beings. ... -
Influence of pH on the optical and structural properties of spin coated CeO2-TiO2 thin films prepared by sol-gel process
(Elsevier Science Bv, 2007)Optical and structural properties of mixed CeO2-TiO2 thin films have been investigated by varying the pH of the coating sol. The films were prepared by sol-gel process using spin-coating technique with a spin speed of 2500 ... -
