A reflectance-based computer aided modelling tool for high speed/high frequency communication systems
(IEEE, 2001)
A reflectance-based method is presented to model the measured or computed data, obtained from a "passive one-port physical device" by means of its Darlington equivalent. The basis of the new modelling tool rests on the ...
Representation of speech signals by single signature base function within optimum frame length
(IEEE, 2000)
Before this study, we proposed a novel method to represent signals in terms of, so called, “Signature Base Functions-SBF" which were extracted from the physical features of the waveform under consideration. SBF were ...
Volumetric imaging using 2D capacitive micromachined ultrasonic transducer arrays (CMUTs): Initial results
(IEEE, 2002)
This paper presents the first volumetric images obtained using a 2D CMUT array with through-wafer via interconnects. An 8×16-element portion of a 32×64-element array flip-chip bonded onto a glass fanout chip was used in ...
Subarray delta-sigma beamforming for ultrasonic imaging
(IEEE, 2002)
We present a beamforming architecture based on subarray processing with non-uniform oversampling 1-bit delta-sigma (??) modulation. The subarray processing combines conventional phased array and synthetic aperture approaches ...
Üç boyutlu akustik görüntüleme için ön alıcı-verici tümdevre
(IEEE, 2004)
Tıbbi ultrasonik görüntüleme sistemleri, genel olarak bir çevirici elemanı ve akustik işaretin üretilip algılanmasından sorumlu elektronik oluşmaktadır. Tek boyutlu dönüştürücü dizileriyle, incelenmekte olan ortamın iki ...
Integrated ultrasonic imaging systems based on CMUT arrays: Recent progress
(IEEE, 2004)
This paper describes the development of an ultrasonic imaging system based on a two-dimensional capacitive micromachined ultrasonic transducer (CMUT) array. The transducer array and front-end electronics are designed to ...
The confluent edge and tip singularities of the electromagnetic wave on material sheets
(2004)
The singularities of the electromagnetic wave at sharp edges and tips effect the performance of electric devices and, hence, requires serious precautions at both the design and production stages. Furthermore, in theoretical ...
Diffraction of two-dimensional high-frequency electromagnetic waves by a locally perturbed two-part impedance plane
(2004)
Among the wave propagation problems, those connected with half-spaces bounded by sectionally homogeneous boundaries take important place because they are motivated by microwave applications. If the boundary are of three ...
Real-time video frame differentiator based on DDR3 SDRAM memory interface
(IEEE Computer Society, 2018-08)
In this paper, design of a real-time video frame differentiator based on an external memory interface is proposed. Furthermore, implementation and simulation processes of the design is discussed. The proposed design is ...
A discussion on spatiotemporal filtering on a third generation real-time cellular neural network processor
(IEEE Computer Society, 2016)
A third generation Real-Time Cellular Neural Network (CNN) Processor (RTCNNP-v3) is a CNN emulator currently being implemented targeting FPGA devices. Thanks to the frame buffer support of the RTCNNP-v3 it will be possible ...
