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 ...
A monitoring and control system integrated with smart phones for the efficient use of underground water resources in agricultural product growing
(Hitit University, 2017)
Monitoring and control system is very important for crop development process in agriculture zones. A structure which is carried out based on the type of the product with the knowledge of temperature and humidity values of ...
Modified ultrasound despeckling assessment index for the Field II simulated cyst image
(Institution of Engineering and Technology, 2017)
Various methods have been proposed to reduce speckle noise, which decreases image quality in ultrasound images. The Field II simulated cyst image consists of three classes and is used to compare a proposed despeckle filter ...
Improvements on deinterleaving of radar pulses in dynamically varying signal environments
(Elsevier Inc., 2017)
An electronic support system receiver which is a passive receiver picks up an interleaved stream of pulses and extracts their pulse parameters. These parameters are sent to a deinterleaving subsystem which sorts them and ...
Large bandwidth mode order converter by differential waveguides
(Optical Society of American (OSA), 2015)
In this article, we propose a large bandwidth mode-order converter design by dielectric waveguides with equal lengths but different cross-sectional areas. The efficient conversion between even and odd modes is verified by ...
Üç ayrık ölçüme dayalı parabol algoritması ile termoelektrik modülün Imax, Vmax ve Emax parametrelerinin belirlenmesi
(Gazi University, 2016)
Termoelektrik (TE) modüllerin performansının belirlenmesi amacıyla çeşitli metotlar geliştirilmiştir. Bunlardan biri de Ahıska vd. tarafından geliştirilen sıcaklık, akım ve gerilim gibi kolaylıkla ölçülebilir parametreleri ...
AC chopper application and benefits of auxiliary windings for PSC motors
(2013)
In this work, a novel driver circuit is designed for permanent split capacitor motors (PSC). With this driver circuit, semi-conductive technology is used in place of cumulative winding for this type of motors that are ...
Servo control education tool for industrial applications
(2010)
In this study, a training set consisting of servo motors is designed to assist development of the students, especially who are in electrical, electronics and mechanical engineering, in industrial field. For this training ...
