Accurate simulation of reflector antennas by the complex source-dual series approach
(Institute of Electrical and Electronics Engineers, 1995-08)The radiation from circular cylindrical reflector antennas is treated in an accurate manner for both polarizations. The problem is first formulated in terms of the dual series equations and then is regularized by the ... -
Control of the Responsivity and the detectivity of superconductive edge-transition YBa2Cu3O7-x bolometers through substrate properties
(Optical Society of America, 1999-08-01)The detectivity D* limits of YBa2Cu3O7-x bolometer on 0.05-cm-thick crystalline substrates are investigated, and a method to increase D* to greater than 10(9) (cm Hz(1/2))/W at a 20-mu m wavelength is proposed. Because the ... -
Major sources of collocational errors made by EFL learners at Koya University
(Bilkent University, 2010)The aim of the present study was to explore the main sources of collocational errors made by learners of English as Foreign Language (EFL). To address this issue, 40 Kurdish seniors studying EFL at Koya University’s ... -
Micromachinable leaky wave air transducers
(IEEE, 1997-11)In this paper, ultrasonic air transducers which use the lowest order antisymmetric (A/sub 0/) mode Lamb waves in a thin plate as a means of efficient coupling of ultrasonic energy to air are discussed. For a silicon plate ... -
Semantic argument frequency-based Multi-Document Summarization
(2009)Semantic Role Labeling (SRL) aims to identify the constituents of a sentence, together with their roles with respect to the sentence predicates. In this paper, we introduce and assess the idea of using SRL on generic ... -
Simulating a wavelength-size 2-D lens with an accurate numerical method
(IEEE Computer Society, 2001)The effect of a localized light source directivity improvement due to an arbitrarily shaped dielectric cylinder taken as a 2-D model of a dielectric lens is studied. The source is simulated by the field of a complex ... -
Surface-modified bacterial nanofibrillar PHB scaffolds for bladder tissue repair
(Taylor and Francis Ltd., 2016)The aim of the study is in vitro investigation of the feasibility of surface-modified bacterial nanofibrous poly [(R)-3-hydroxybutyrate] (PHB) graft for bladder reconstruction. In this study, the surface of electrospun ...
