Low complexity inter-mode selection for H.264
(IEEE, 2006)
The coding efficiency of the H.264/AVC standard enables the transmission of high quality video over bandwidth limited networks. Due to the use of multiple Macroblock (MB) partitions, the Motion estimation module has extremely ...
Reflection and transmission of nonlinear waves from arterial branching
(Elsevier Ltd, 2006-10)
In this work, treating the arteries as a prestressed thin walled elastic tube and the blood as an inviscid fluid, we have studied the reflection and transmission of nonlinear waves from arterial branching, through the use ...
Dual-annular-ring CMUT array for forward-looking IVUS imaging
(IEEE, 2006)
We investigate a dual-annular-ring CMUT array configuration for forward-looking intravascular ultrasound (FL-IVUS) imaging. The array consists of separate, concentric transmit and receive ring arrays built on the same ...
Phase transitions of kappa-carrageenan gels in various types of salts
(John Wiley & Sons Inc, 2006-11-05)
Sol-gel and gel-sol phase transitions of K-carrageenan in various types of salts were studied using photon transmission technique. Here, LiCl, NaCl, KCl, MgCl2, CaCl2, and SrCl2 were chosen as the proper salts for the ...
Equivalent dose in quartz from young samples using the SAR protocol and the effect of preheat temperature
(Pergamon-Elsevier Science Ltd, 2006-09)
Major concerns in the dating of samples younger than a few hundred years by the optically stimulated luminescence (OSL) technique are thermal transfer and partial bleaching. Thermal transfer during preheating enhances the ...
An integrated circuit with transmit beamforming and parallel receive channels for real-time three-dimensional ultrasound imaging
(IEEE, 2006)
We present the design of an integrated circuit (IC) that will be flip-chip bonded to a 16 x 16-element CMUT array. The IC provides 16 receive channels which can be configured to receive along either of the array diagonals ...
Beamforming and hardware design for a multichannel front-end integrated circuit for real-time 3D catheter-based ultrasonic imaging
(SPIE-Int Soc Optical Engineering, 2006)
We are working on integrating front-end electronics with the ultrasound transducer array for real-time 3D ultrasound imaging systems. We achieve this integration by flip-chip bonding a two-dimensional transducer array to ...
Volumetric imaging using fan-beam scanning with reduced redundancy 2D arrays
(IEEE, 2006)
Phased array processing with a fully populated 2D array produces the best image quality but requires excessive number of active parallel front-end channels. Here we explore four array designs with reduced redundancy in ...
On the comparative results of "SYMPES: A new method of speech modeling"
(Elsevier GMBH, 2006)
In this paper, the new method of speech modeling which is called SYMPES (A Novel Systematic Procedure to Model Speech Signals via Predefined "Envelope and Signature Sequences") is introduced and it is compared with the ...
Study on critical behaviour in N-isopropyl acrylamide gels by using fluorescence technique
(Taylor & Francis Group, 2006-11)
The steady state fluorescence (SSF) technique was used to study the sol-gel transition for the solution free radical crosslinking copolymerization of N-isopropyl acrylamide (NIPA), with N,N'-methylenebis (acrylamide) (BIS) ...
