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, ...
Power allocation for cooperative communications
(IGI Global, 2009)
In this chapter, we review the optimal power allocation policies for fading channels in single user and multiple access scenarios. We provide some background on cooperative communications, starting with the relay channel, ...
Biclustering expression data based on expanding localized substructures
(Springer-Verlag Berlin Heidelberg, 2009)
Biclustering gene expression data is the problem of extracting submatrices of genes and conditions exhibiting significant correlation across both the rows and the columns of a data matrix of expression values. We provide ...
A tunable analog delay element for high-frequency dynamic beamforming
(IEEE, 2009)
Implementing beamforming for high frequency arrays is challenging because of the accurate delay requirements at high frequencies. High frequency digital beamforming is not suitable for catheter based applications as a large ...
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 ...
Evaluation of CMUT annular arrays for side-looking IVUS
(IEEE, 2009)
Side-looking (SL) IVUS probes are extensively used for management of cardiovascular diseases. Currently SL-IVUS imaging probes use either a single rotating transducer element or solid-state arrays. Probes with single ...
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 ...
Reflectance data model with mixed lumped and distributed elements for wireless communication systems
(IEEE, 2005)
In this paper, a new method is presented to model the given reflectance data obtained from a "passive one-port physical device", as a lossless two port consists of lumped and distributed elements. Basis of the new method ...
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 ...
A lumped circuit model for the radiation impedance of a 2D CMUT array element
(IEEE, 2005)
Elements of a 2D array used for 3D acoustic imaging have dimensions smaller than half of the acoustic wavelength due to the Nyquist criteria for spatial sampling. Therefore, analyses involving circuit models for the array ...
