Minimum Length Scheduling for Full Duplex Time-Critical Wireless Powered Communication Networks
(IEEE, 2020)Radio frequency (RF) energy harvesting is key in attaining perpetual lifetime for time-critical wireless powered communication networks (WPCNs) due to full control on energy transfer, far field region, small and low-cost ... -
Mixed Element Networks With Series Capacitors Separated By Unit Elements
(World Scientific, 2020)In this work, high-pass mixed-element networks with series capacitors separated by unit elements are analyzed. First, the description of the networks via two frequency variables is given. Then, explicit coefficient relations ... -
Mobile Application Development for the Estimation of Recurrence in Post-Operative Kidney Cancer Cases
(IEEE, 2018)In this paper a post-operative recurrence estimation tool called Sorbellini's nomogram for the kidney cancer patients showing no metastates is introduced and a novel application for mobile devices based on this model is ... -
A Mobile Channel Model for VLC and Application to Adaptive System Design
(IEEE-INST Electrical Electronics Engineers Inc, 2017)In this letter we propose a realistic channel model for visible light communication (VLC) assuming a mobile user. Based on non-sequential ray tracing we first obtain channel impulse responses for each point over the user ... -
Model based predictive rate controller for video streaming
(2009)Due to the heterogeneous structure of networks video streaming over lossy IP networks is very important issues. Infrastructure of the Internet exhibits variable bandwidths delays congestions and time-varying packet losses. ... -
Modeling and Equalization of Indoor Visible Light Channnels
(IEEE, 2016)In this paper a computationally efficient method is proposed for modeling the indoor visible light communications (VLC) channels using a non-sequential ray tracing technique. We created three dimensional realistic simulation ... -
Modeling based real frequency technique
(Elsevier GMBH Urban & Fischer Verlag, 2008)Usually commercially available software tools are used to design matching networks for wireless communication systems. But a properly selected matching network topology with good initial element values must be supplied to ... -
Modeling of Visible Light Channels and Performance Analysis of ACO-OFDM
(IEEE, 2015)Spectrum scarcity of traditional radio communication has led communication engineers to find new alternatives. Indoor visible light communication is one alternative to solve this problem since its spectrum is not regulated ... -
Modeling of Wind Effects on Stratified Flows in Open Channels: A Model for the Istanbul Strait (Bosphorus)
(2016)Stratified flows in open channels arise as a result of density or surface level differences. If the channel is connected to a basin at one or both ends, strong winds originating from the basin cause the "wind setup" effect ... -
Modeling the optical properties of WO(3) and WO(3)-SiO(2) thin films
(Elsevier Science Bv, 2008)The optical properties and surface morphology of sol-gel spin coated WO(3) and WO(3)-SiO(2) composite films annealed at 250 and 400 degrees C are investigated. For the purpose of extracting the optical parameters of the ... -
Modelling of Swelling by the Fluorescence Technique in Kappa Carrageenan Gels
(Amer Inst Physics, 2011)Kappa (-kappa) carrageenan gels prepared with various carrageenan concentrations in pure water were completely dried and then swelled in water vapor. Steady state fluorescence measurements were performed using a spectrometer ... -
Models for relief routing: equity efficiency and efficacy
(Pergamon-Elsevier Science Ltd, 2012)In humanitarian relief operations vehicle routing and supply allocation decisions are critically important. Similar routing and allocation decisions are studied for commercial settings where efficiency in terms of minimizing ... -
Modified Q-Based Real Frequency Design of Narrowband Impedance Equalizer with Complex Terminations
(World Scientıfic Publ Co Pte Ltd, 2019)In this paper, real frequency design equations of narrowband impedance matching network with complex terminations are derived; which are used to design L, Pi and T type of networks. In the approach, there is no need to ... -
The modifier effects of chymotrypsin and trypsin enzymes on fluorescence lifetime distribution of "N-(1-pyrenyl)maleimide-bovine serum albumin" complex
(Pergamon-Elsevier Science LTD, 2016)Chymotrypsin and trypsin are the well known proteolytic enzymes, both of which are synthesized in the pancreas as their precursors the inactive forms; chymotrypsinogen and trypsinogen and then are released into the duodenum ... -
Molecular docking study based on pharmacophore modeling for novel PhosphodiesteraseIV ınhibitors
(Wiley-VCH Verlag GmbH, 2012)In this study pharmacophore modelling was carried out for novel PhosphodiesteraseIV (PDEIV) inhibitors. A pharmacophore-based virtual screening which resulted in 1959 hit compounds was performed with six chemical databases. ... -
