The analysis of tissue temperature rise caused by linear array transducers with Program Spheresum
(Institute of Electrical and Electronics Engineers Inc., 2016)
Diagnostic ultrasounds transmit sound waves into the body, and thus reveal important information about it. Because the transmitted sound waves cause tissue heating, diagnostic ultrasounds can produce adverse biologic effects ...
Thin wideband infrared metamaterial absorber with coplanar metallic patches of different sizes
(Institute of Electrical and Electronics Engineers Inc., 2016)
Infrared absorber concept is a vibrant research topic because of the importance of real world applications such as infrared detectors, thermal coolers and energy harvesters. In this paper, we propose and numerically analyze ...
The effects of the median filter with different window sizes for ultrasound image
(Institute of Electrical and Electronics Engineers Inc., 2017)
Ultrasound is widely used in medical imaging. Unfortunately, speckle noise decreases the quality of the ultrasound image. One of the filters to reduce speckle noise in ultrasound image is the median filter. The median ...
Broadband one way propagation via dielectric waveguides with unequal effective index
(Institute of Electrical and Electronics Engineers Inc., 2014)
We present an efficient approach for broad band one way propagation of light by parallel and unequal dielectric waveguides leading different effective phase shifts. Three dimensional numerical simulations show that 30% ...
Wide bandwidth absorption in the MWIR region using a thin and simple metamaterial absorber
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, metamaterial absorber structures that operate in the mid-wave infrared (MWIR) region are presented. The advantage of the design stems from the high absorptance in the region of interest and the ease of ...
Low velocity impact response of glass fiber reinforced aluminium foam sandwich
(European Conference on Composite Materials, ECCM, 2012)
The aim of this study was the analysis of the bending and the low - velocity impact response of aluminium foam sandwich reinforced by the outer skins made of glass fiber reinforced epoxy matrix and the results were compared ...
Elastoplastic stress analysis of functionally graded disc under internal pressure-complas XII
(2013)
The study deals with elastoplastic stress analysis of a hollow disk made of functionally graded materials (FGMs) subjected to an internal pressure. The material properties of disc are assumed to vary radially according to ...
Design of sma based actuators used in robotics
(2013)
This work introduces to Shape Memory Alloy (SMA) using in Robotics as actuators. We investigated a quadruped platform actuated by SMAs which act with variable elasticity. SMAs ought to prove necessary forces for all gaits. ...
Pesticide effect on kinetic properties of catalase enzyme
(Hitit Üniversitesi, 2017)
Catalase is a metalloenzyme. Contains Cu(II) as the metal ion. It is a detoxification agent for the H2O2 compound and protects tissues and cells from oxidative damage [1]. Cryogels are synthetic materials generally used ...
The use of BMWP and ASPT indices for evaluation of water quality according to macroinvertebrates in Kucuk Menderes River (Turkey)
(De Gruyter Open Ltd, 2016)
This study was carried out in the Kucuk Menderes River basin in order to determine the water quality and investigate the environmental quality and the applicability of both the Biological Monitoring Working Party (BMWP) ...
