Drying of Polyacrylamide Composite Gels Formed with Various Kappa- Carrageenan Content
(Springer/Plenum Publishers, 2011)Drying of polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composite gels were monitored by using steady-state fluorescence technique. Disc shaped gels were formed from acrylamide (AAm) and N N'- methylenebisacrylamide(Bis) ... -
Derivation of the optical constants of spin coated CeO2-TiO2-ZrO2 thin films prepared by sol-gel route
(Pergamon-Elsevier Science Ltd, 2011)Ternary thin films of cerium titanium zirconium mixed oxide were prepared by the sol-gel process and deposited by a spin coating technique at different spin speeds (1000-4000 rpm). Ceric ammonium nitrate ce(NO3)(6)(NH4)(2) ... -
Reliability-Oriented bioinformatic networks visualization
(Oxford University Press, 2011)We present our protein-protein interaction (PPI) network visualization system RobinViz (reliability-oriented bioinformatic networks visualization). Clustering the PPI network based on gene ontology (GO) annotations or ... -
Low-Complexity MAP-Based Successive Data Detection for Coded OFDM Systems Over Highly Mobile Wireless Channels
(IEEE-INST Electrical Electronics Engineers Inc, 2011)This paper is concerned with the challenging and timely problem of data detection for coded orthogonal frequency-division multiplexing (OFDM) systems in the presence of frequency-selective and very rapidly time varying ... -
Holocene coastal change in the ancient harbor of Yenikapi-Istanbul and its impact on cultural history
(Academic Press Inc Elsevier Science, 2011)An extensive rescue excavation has been conducted in the ancient harbor of Istanbul (Yenikapi) by the Sea of Marmara revealing a depositional sequence displaying clear evidence of transgression and coastal progradation ... -
Do structural breaks in exchange rate volatility matter? Evidence from Asia-Pacific currencies
(Bilgesel Yayincilik San & Tic Ltd, 2011)Using the U.S. dollar exchange rate return series of three major Asia-Pacific currencies this paper investigates the empirical relevance of structural breaks in exchange rate volatilities. We find significant evidence of ... -
Space-Time Block Coded Spatial Modulation
(IEEE-INST Electrical Electronics Engineers Inc, 2011)A novel multiple-input multiple-output (MIMO) transmission scheme called space-time block coded spatial modulation (STBC-SM) is proposed. It combines spatial modulation (SM) and space-time block coding (STBC) to take ... -
Measuring bank branch performance using Data Envelopment Analysis (DEA): The case of Turkish bank branches
(Academic Journals, 2011)The aim of this study is to develop a performance model for measuring the relative efficiency and potential improvement capabilities of bank branches by identifying their strengths and weaknesses. Another purpose is to ... -
Computing trade-offs in robust design: Perspectives of the mean squared error
(Pergamon-Elsevier Science Ltd, 2011)Researchers often identify robust design as one of the most effective engineering design methods for continuous quality improvement. When more than one quality characteristic is considered an important question is how to ... -
Joint Detection of Primary Systems Using UWB Impulse Radios
(IEEE-INST Electrical Electronics Engineers Inc, 2011)Regulation in Europe and Japan requires the implementation of detect-and-avoid (DAA) techniques in some bands for the coexistence of licensed primary systems and secondary ultra wideband (UWB) systems. In a typical coexistence ... -
Bound free electron-positron pair production accompanied by giant dipole resonances
(Amer Physical Soc., 2011)At the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) for example virtual photons produce many particles. At small impact parameters where the colliding nuclei make peripheral collisions photon ... -
Fluorescence study on drying of iota-carrageenan gels at different temperatures prepared with various CaCl2 content
(Springer, 2011)The influence of temperature and salt content on drying was investigated by using steady-state fluorescence (SSF) technique. Supporting gravimetric and volumetric measurements were also carried out during drying of gels ... -
Performance of IEEE 802.15.4a Systems in the Presence of Narrowband Interference
(IEEE, 2011)The regulatory agencies in Europe and Japan require the implementation of avoidance techniques in some bands to reduce interference to licensed systems. Accordingly ultra-wideband impulse radio (UWB-IR) based Wireless ... -
The Effect of Channel Models on Compressed Sensing Based UWB Channel Estimation
(IEEE, 2011)Ultra-wideband (UWB) multipath channels are assumed to have a sparse structure as the received consecutive pulses arrive with a considerable time delay and can be resolved individually at the receiver. Due to this sparse ... -
The Turkish handmade carpet industry: an analysis in comparison with select Asian countries
(Taylor & Francis Ltd, 2011)The main purpose of this paper is to analyze the Turkish handmade carpet industry and to compare it with select Far East countries. In particular the Turkish handmade carpet industry is compared with the handmade carpet ... -
