Multiple annular ring capacitive micromachined ultrasonic transducer arrays for forward-looking intravascular ultrasound imaging catheters
(American Society of Mechanical Engineers (ASME), 2007)
We investigate multiple-annular-ring CMUT array configuration for forward-looking intravascular ultrasound (FL-IVUS) imaging. This configuration has the potential for independent optimization of each ring and uses the ...
Probability distributions and variances of quadratic loss functions
(2006)
The use of quadratic loss functions has been advocated in quality engineering and experimental design for process optimization and robust design. We derive theoretical density functions and variances for nominal-the-best, ...
Wavelet-based image compression by hierarchical quantization indexing
(IEEE, 2009)
In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet coefficients. A hierarchical classification map is defined in each wavelet subband, which describes the ...
Circuit model for given reflectance data constructed with mixed lumped and distributed elements for high speed/high frequency communication systems
(IEEE, 2005)
In this paper, a reflectance-based "non linear interpolation method" is presented to model the measured or computed data, obtained from a "passive one-port physical device" using mixed lumped and distributed elements. Mixed ...
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 ...
Extremum seeking control of uncertain systems
(Işık University Press, 2017)
Extremum seeking is used in control problems where the reference trajectory or reference set point of the system is not known but it is searched in real time in order to maximize or minimize a performance function representing ...
Optimal project duration for resource leveling
(Elsevier Science BV, 2018-04-16)
Resource leveling is important in project management as resource fluctuations are costly and undesired. Typically, schedules with better resource profiles are obtained by shifting the activities within their float times ...
Design of a global extremum seeking algorithm for an omni-directional robot model
(Romanian Soc Control Tech Informatics, 2017-06)
A global extremum seeking algorithm is developed for a mobile robot model where the aim is to find the location of the most powerful signal source among the others. In other words, the control problem is to seek the global ...
Subset selection for tuning of hyper-parameters in artificial neural networks
(IEEE, 2017)
Hyper-parameters of a machine learning architecture define its design. Tuning of hyper-parameters is costly and for large data sets outright impractical, whether it is performed manually or algorithmically. In this study ...
