Size-dependent self-organization of colloidal particles on chemically patterned surfaces
(SP Zhejiang University Press, 2006-04-14)
A study of the self-organization of colloidal particles during the evaporation of particle solutions on chemically patterned surfaces is presented. On a surface with hydrophilic and hydrophobic regions, colloidal particles ...
Coherent-array imaging using phased subarrays. Part I: Basic principles
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)
The front-end hardware complexity of a coherent array imaging system scales with the number of active array elements that are simultaneously used for transmission or reception of signals. Different imaging methods use ...
Annular-ring CMUT arrays for forward-looking IVUS: Transducer characterization and imaging
(IEEE, 2006-02)
In this study, a 64-element, 1.15-mm diameter annular-ring capacitive micromachined ultrasonic transducer (CMUT) array was characterized and used for forward-looking intravascular ultrasound (IVUS) imaging tests. The array ...
Ceramic encapsulated latex composites
(Elsevier Inc, 2006-04-15)
This work reports the encapsulation of latex particles in Al(2)O(3)-polystyrene (PS) composite films. These films were prepared from PS particles in Al(2)O(3) dispersion at room temperature in various latex contents. ...
Design and analysis of classifier learning experiments in bioinformatics: survey and case studies
(IEEE Computer Soc, 2012-12)
In many bioinformatics applications, it is important to assess and compare the performances of algorithms trained from data, to be able to draw conclusions unaffected by chance and are therefore significant. Both the design ...
Relocating sensor nodes to maximize cumulative connected coverage in wireless sensor networks
(Molecular Diversity Preservation Int, 2008-04)
In order to extend the availability of the wireless sensor network and to extract maximum possible information from the surveillance area, proper usage of the power capacity of the sensor nodes is important. Our work ...
An analog integrated circuit beamformer for high-frequency medical ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2012-10)
We designed and fabricated a dynamic receive beamformer integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer IC is suitable for integration with an annular array transducer for high-frequency (30-50 MHz) ...
Integration of 2D CMUT arrays with front-end electronics for volumetric ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)
For three-dimensional (3D) ultrasound imaging, connecting elements of a two-dimensional (2D) transducer array to the imaging system's front-end electronics is a challenge because of the large number of array elements and ...
Robust stability analysis of a class of neural networks with discrete time delays
(Pergamon-Elsevier Science Ltd, 2012-05)
This paper studies the existence, uniqueness and global asymptotic stability of the equilibrium point for the class of neural networks with discrete constant time delays under parameter uncertainties. The class of the ...
Dissolution and subsequent re-crystallization as zeroing mechanism, thermal properties and component resolved dose response of salt (NaCl) for retrospective dosimetry
(Pergamon-Elsevier Science Ltd, 2011-09)
In the present study we report dosimetric properties of iodized salt aiming at using it as an accidental luminescent dosimeter. It was found that the very good sensitivity of its main dosimetric peak is strongly affected ...
