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 ... -
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 ... -
An integrated model for visualizing biclusters from gene expression data and PPI networks
(2010)We provide a model to integrate the visualization of biclusters extracted from gene expresion data and the underlying PPI networks. Such an integration conveys the biologically relevant interconnection between these two ... -
An Integrated Software Architecture for Bandwidth Adaptive Video Streaming
(World Acad Sci Eng & Tech-Waset, 2008)Video streaming over lossy IP networks is very important issues due to the heterogeneous structure of networks. Infrastructure of the Internet exhibits variable bandwidths delays congestions and time-varying packet losses. ... -
