The homogeneity map method for speckle reduction in diagnostic ultrasound images
(Elsevier B.V., 2015)
This paper proposes a new method to reduce speckle noise in diagnostic ultrasound images by improving the speckle reduction capacity of an edge-sensitive filter. A homogeneity map is generated according to the local ...
Health risk assessment of selected pesticide residues in green pepper and cucumber
(Elsevier Ltd, 2018)
This report describes levels of 170 pesticide residues in green pepper and cucumber marketed in Turkey. The report also comprises the outcome of the consumer risk assessment of selected pesticides. In total, 725 samples ...
Assessment of an IGCC based trigeneration system for power, hydrogen and synthesis fuel production
(Elsevier Ltd, 2016)
In this study, an integrated gasification combined cycle based trigeneration system is proposed to produce power, hydrogen and various Fischer-Tropsch (FT) synthesis products. The proposed plant consists of an (a) air ...
Novel 2D micro-porous metal-organic framework for hydrogen storage
(Elsevier Ltd, 2016)
A novel two dimensional Metal-Organic Framework (MOF) structured compound with trimesic acid (TMA), 1,10 Phenantroline (Phen) and Cu(II) building blocks were synthesized and characterized experimentally. Then Grand Canonical ...
Energy and exergy analyses of hydrogen production by coal gasification
(Elsevier Ltd, 2017)
In this study, we examine an integrated coal based gasification system developed for hydrogen production and power generation. The proposed plant consists of air separation unit, gasification unit, gas cooling and cleaning ...
Synthesis of Zn(II) ion-imprinted polymeric adsorbent for selective removal of zinc from aqueous solutions
(2011)
In this study, Zn(II)-imprinted polymer microbeads were synthesized for selective removal of Zn(II) from aqueous solutions. The microbeads were prepared using methacrylic acid and 1,4-vinyl pyrrolidone as functional monomers, ...
An experimental study on combustion, engine performance and exhaust emissions in a HCCI engine fuelled with diethyl ether-ethanol fuel blends
(Elsevier, 2016)
In this study, the effects of diethyl ether–ethanol fuel blends on HCCI combustion, engine performance and exhaust emissions were investigated experimentally in a single cylinder, port injection HCCI engine. In the ...
Broadband LWIR and MWIR metamaterial absorbers with a simple design topology: Almost perfect absorption and super-octave band operation in MWIR band
(OSA - The Optical Society, 2017)
Infrared absorbers are essential structures in the design of thermal emitters and thermal infrared imagers. In this study, we propose simple topologies of wideband metamaterial absorbers operating in the long-wave infrared ...
Ultra-broadband long-wavelength infrared metamaterial absorber based on a double-layer metasurface structure
(OSA - The Optical Society, 2017)
In this paper, we report a metamaterial absorber design that achieves a broad absorption band encompassing the whole long-wavelength infrared (LWIR) region. The structure consists of two parallel metasurfaces buried in an ...
Efficient and broadband guided wave one-way mode-order conversion with theoretical and numerical analysis
(Optical Society of American (OSA), 2013)
In this article, an efficient method of asymmetric conversion of guided modes is investigated. From a basic excitation consisting of (mainly) the lowest-order mode of the input multimode strip waveguide, we achieve a ...
