Early Steps in Automated Behavior Mapping via Indoor Sensors
(MDPI, 2017)Behavior mapping (BM) is a spatial data collection technique in which the locational and behavioral information of a user is noted on a plan layout of the studied environment. Among many indoor positioning technologies we ... -
The effect of a bump in an elastic tube on wave propagation in a viscous fluid of variable viscosity
(Elsevier Science, 2007)In the present work treating the arteries as a thin walled prestressed elastic tube with a bump and the blood as a Newtonian fluid of variable viscosity we have studied the propagation of weakly nonlinear waves in such a ... -
Effect of Inter-Block-Interference-Free Region on Compressed Sensing Based Channel Estimation in TDS-OFDM Systems
(IEEE, 2016)Time domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) is the basis technology for digital television standard (DTV) employed in some countries thanks to its high spectral efficiency when compared ... -
Effect of inter-block-interference-free region on compressed sensing based channel estimation in TDS-OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2016)Time domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) is the basis technology for digital television standard (DTV) employed in some countries thanks to its high spectral efficiency when compared ... -
Effect of the Channel Estimation Error on the Performance of the Source Estimator in a Wireless Sensor Network with Orthogonal Channels
(IEEE, 2008)In this work effect of the channel estimation error on the MSE performance of the source estimator in a wireless sensor network with orthogonal flat fading channels is studied. A two-phase approach was employed where in ... -
The effects of higher-order approximations in a fluid-filled elastic tube with stenosis
(Verlag der Zeitschrift fur Naturforschung, 2006)Treating arteries as thin-walled prestressed elastic tubes with a narrowing (stenosis) and blood as an inviscid fluid we study the propagation of weakly nonlinear waves in such a fluid-filled elastic tube by employing the ... -
Electrochromic properties of heat-treated thin films of CeO2-TiO2-ZrO2 prepared by sol-gel route
(Elsevier Science Bv, 2008)CeO2-TiO2-ZrO2 thin films were prepared using the sol-gel process and deposited on glass and ITO-coated glass substrates via dipcoating technique. The samples were heat treated between 100 and 500 degrees C. The heat ... -
Energy Aware Multi-Hop Routing Protocol for WSNs
(IEEE, 2018)In this paper we propose an energy-efficient multi-hop routing protocol for wireless sensor networks (WSNs). The nature of sensor nodes with limited batteries and inefficient protocols are the key limiting factors of the ... -
An energy efficient routing algorithm (X-Centric routing) for sensor networks
(INT INST Informatics & Systemics, 2011)Recent developments in wireless communications and electronics technologies have enabled the progress in low cost sensor networks. Sensor networks differ from traditional networks in several ways such as the severe energy ... -
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 ... -
Extending the lifetime of WSNs with Maximum Energy Selection Algorithm (MESA)
(Institute of Electrical and Electronics Engineers Inc., 2017)The limited battery supply of a sensor node is one of the most important factors that limit the lifetime of the WSNs. As a consequence increasing the lifetime of WSNs through energy efficient mechanisms has become a ... -
Fast multi-view face trackingwith pose estimation
(2008)In this paper a fast and an effective multi-view face tracking algorithm with head pose estimation is introduced. For modeling the face pose we employ a tree of boosted classifiers built using either Haar-like filters or ... -
First impressions on social network sites: Impact of self-disclosure breadth on attraction
(Academic Conferences and Publishing International Limited, 2017)This paper reports the results of two experiments that investigate the relationship between the quantity of information disclosed on an SNS profile and profile viewers' first impressions of the profile owner. Both experiments ... -
FLEX: A Modular Software Architecture for Flight License Exam
(Springer-Verlag Berlin, 2010)This paper is about the design and implementation of an examination system based on World Wide Web. It is called FLEX-Flight License Exam Software. We designed and implemented flexible and modular software architecture. ... -
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 ... -
