Hierarchical b-Matching
(Springer Science and Business Media Deutschland GmbH, 2021)
A matching of a graph is a subset of edges no two of which share a common vertex, and a maximum matching is a matching of maximum cardinality. In a b-matching every vertex v has an associated bound bv, and a maximum ...
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 ...
Real-time range sensing with a Scheimpflug camera and a single custom sensor/processor chip
(SPIE-Int Soc Optical Engineering, 2003)
An image-based range sensing technique is presented. The technique is originally considered for highway collision avoidance applications but its generality makes it suitable for application in robotics, manufacturing and ...
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 ...
Blind channel estimation for space-time coding systems with Baum-Welch algorithm
(IEEE, 2002)
In recent years, space-time coding is proposed to provide significant capacity gains over the traditional communication systems in fading wireless channels. In this paper, we consider the problem of blind estimation of the ...
A miniature real-time volumetric ultrasound imaging system
(SPIE-Int Soc Optical Engineering, 2005)
Progress made in the development of a miniature real-time volumetric ultrasound imaging system is presented. This system is targeted for use in a 5-mm endoscopic channel and will provide real-time, 30-mm deep, volumetric ...
Dual electrode capacitive micromachined ultrasonic transducer array for 1-D intracardiac echocardiography (ICE)
(American Society of Mechanical Engineers (ASME), 2007)
We designed and fabricated a 64 element 1-D linear dual electrode Capacitive Micromachined Ultrasonic Transducer (CMUT) array operating at 9.5 MHz for Intracardiac Echocardiography (ICE). The dual electrode CMUT structure ...
Micromachined capacitive transducer arrays for intravascular ultrasound
(SPIE, 2005)
Intravascular ultrasound (IVUS) imaging has become an essential imaging modality for the effective diagnosis and treatment of cardiovascular diseases during the past decade enabled by innovative applications of piezoelectric ...
Forward-looking IVUS imaging using an annular-ring CMUT array
(IEEE, 2005)
A 64-element, 1.15mm diameter annular-ring CMUT array was characterized and used for forward-looking IVUS imaging tests. The array was manufactured using low temperature processes suitable for CMOS electronics integration ...
