A confidence ellipsoid approach for measurement cost minimization under Gaussian noise
(IEEE, 2012-06)The well-known problem of estimating an unknown deterministic parameter vector over a linear system subject to additive Gaussian noise is studied from the perspective of minimizing total sensor measurement cost under a ... -
Detection of MR signal during RF excitation using a transmit array system
(ISMRM, 2012-05)Most of conventional MRI applications are based on a time interleaved approach for RF excitation and signal detection. The idea of concurrent RF excitation and reception was implemented in a few recent studies using sideband ... -
Analysis of B1 mapping by Bloch Siegert shift
(ISMRM, 2012-05)The Bloch-Siegert shift is a new phase-based B1 mapping method [1]. This method utilizes the fact that for a large off-resonance frequency, square of the B1 field magnitude is proportional to the phase. In this study, ... -
Decreasing SAR of a multi-dimensional central brightening inhomogeneity correction pulse using nonlinear gradient fields and VERSE
(ISMRM, 2012-05)To correct for B1 inhomogeneity artifacts, multi-dimensional pulses are widely used. However, such pulses increase SAR significantly. In this study, we compare, and combine two SAR reduction methods, the variable rate ... -

Principles of feedback control
(Taylor & Francis, 2004)In this chapter, fundamental properties of feedback control are discussed with engineering applications in mind. However, feedback appears in many other disciplines, such as agriculture, biology, medicine, pharmaceutics, ... -

The root locus method
(CRC Press, 2006)The root locus technique is a graphical tool used in feedback control system analysis and design. It has been formally introduced to the engineering community by W. R. Evans [3,4], who received the Richard E. Bellman Control ... -
Online nonlinear modeling via self-organizing trees
(Elsevier, 2018)We study online supervised learning and introduce regression and classification algorithms based on self-organizing trees (SOTs), which adaptively partition the feature space into small regions and combine simple local ... -
On dynamic wavelength assignment in WDM optical networks
(Springer, 2001)Optical fiber has been used as the physical medium for high rate data transmission since late 1960s. Early applications of optical fiber communications modulated data onto a single optical carrier frequency that is commonly ... -
Space-variant filtering in fractional Fourier domains
(Institute of Physics Publishing, 1995)Signals with significant overlap in both the space and frequency domains may have little or no overlap in a fractional Fourier domain. Spatial filtering in these domains may allow us to eliminate distortion components which ... -
Multiagent systems: learning, strategic behavior, cooperation, and network formation
(Elsevier, 2018)Many applications ranging from crowdsourcing to recommender systems involve informationally decentralized agents repeatedly interacting with each other in order to reach their goals. These networked agents base their ... -
Finding it now: networked classifiers in real-time stream mining systems
(Springer, Cham, 2019)The aim of this chapter is to describe and optimize the specifications of signal processing systems, aimed at extracting in real time valuable information out of large-scale decentralized datasets. A first section will ... -

Closed-Form green's functions and their use in the method of moments
(World Scientific Publishing Company, 1996)Derivation of the spatial-domain, closed-form Green's functions of the vector and scalar potentials are demonstrated for planar media, and their use in conjunction with the method of moments (MoM) is presented. As the ... -
Two-dimensional FIR filters
(CRC Press, 2003)In this chapter, methods of designing two-dimensional (2-D) finite-extent impulse response (FIR) discrete-time filters are described. Two-dimensional FIR filters offer the advantages of phase linearity and guaranteed ... -
Levels of abstraction in computing systems and optical interconnection technology
(Springer, 1998)The design of a computing machine takes place at several levels of abstraction ranging from materials and device engineering to system architecture to high-level software. This system of levels of abstraction enables the ... -
Lens geometries for quantitative acoustic microscopy
(Springer, 1995)The purpose of the first Lemons-Quate acoustic microscope(1) was to image the surfaces of materials or biological cells with a high resolution. Unfortunately, competition with the optical microscope was only partially ...
