M-Band Multiwavelet Systems
(1999-03-20)In this paper we investigate multiwavelet systems whose scaling functions have disjoint support. We demonstrate that, with the exception of a trivial case, this property may not be attained by two band multiwavelet systems. ... -
MAC for real-time applications over random-access time-varying channels
(2004)This thesis introduces mechanisms for support of real-time applications in high-density random-access networks. Random-access Wireless LANs are increasingly being used to support real-time applications such as voice over ... -
Machine recognition of occluded two-dimensional objects in clutter
(1991)This thesis presents a tree search based approach for recognizing occluded 2-D objects in clutter. The planar shapes are represented in terms of their contour line segments. Each is allowed three degrees of freedom (x, y ... -
Macroscopic Ensembles of Aligned Carbon Nanotubes in Bubble Imprints Studied by Polarized Raman Microscopy
(2014)We study the alignment of single-wall carbon nanotubes (SWCNTs) in bubble imprints through polarized Raman microscopy. A hemispherical bubble containing SWCNTs is pressed against a glass substrate, resulting in an imprint ... -
Magneto-optical Kerr effect and magnetic circular dichroism in ferromagnetic indium-manganese-arsenic/gallium-antimony heterostructures
(2002)This thesis describes a Magneto-Optical Kerr Effect (MOKE) and Magnetic Circular Dichroism (MCD) study of ferromagnetism in III-V magnetic semiconductor heterostructures. This work was initiated due to the much recent ... -
Magneto-optical spectroscopy of novel ferromagnetic materials
(2010)Two types of novel ferromagnetic materials, (Ga,Mn)As and Fei/4TaS2, were studied in this dissertation. Interest in (Ga,Mn)As is stimulated by the emerging field of spintronics, which has a potential of bringing a technology ... -
Magnetooptics of Exciton Rydberg States in a Monolayer Semiconductor
(2018)We report 65 T magnetoabsorption spectroscopy of exciton Rydberg states in the archetypal monolayer semiconductor WSe2. The strongly field-dependent and distinct energy shifts of the 2s, 3s, and 4s excited neutral excitons ... -
Magnetoreflection spectroscopy of monolayer transition-metal dichalcogenide semiconductors in pulsed magnetic fields
(2016)The authors describe recent experimental efforts to perform polarization-resolved optical spectroscopy of monolayer transition-metal dichalcogenide semiconductors in very large pulsed magnetic fields to 65 T. The experimental ... -
Magnitude Squared Design of Recursive Filters with the Chebyshev Norm Using a Constrained Rational Remez Algorithm
(1994-10-01)We describe a Remez type exchange algorithm for the design of stable recursive filters for which the Chebyschev norm of H(w) - F(w) is minimized, where H(w) and F(w) are the realized and desired magnitude squared frequency ... -
Magnitude Squared Design of Recursive Filters with the Chebyshev Norm Using a Constrained Rational Remez Algorithm
(1994-05-01)We describe a Remez type exchange algorithm for the design of stable recursive filters for which the Chebyschev norm of H(w) - F(w) is minimized, where H(w) and F(w) are the realized and desired magnitude squared frequency ... -
Magnitude Weighting and Time Segmentation for Phase-Only Reconstruction of Signals
(1981-04-01)Phase-only reconstruction of signals and its application to blind-deconvolution were introduced recently by Oppenheim, and by Hayes, et.al. In this report, we briefly present another description of this phase-only ... -
MAP Detection with Soft Information in an Estimate and Forward Relay Network
(2011)One proven solution for improving the reliability of a wireless channel is to use relays. We analyze the three-node relay network, focusing on the estimate-and-forward (EF) relay protocol, where the relay node estimates ... -
Marginals vs. Covariance in Joint Distribution Theory
(1995-05-01)Recently, Cohen has proposed a method for constructing joint distributions of arbitrary physical quantities, in direct generalization of joint time-frequency representations. In this paper, we investigate the covariance ... -
Markov analysis of multiple-disk prefetching strategies for external merging
(1994-06-06)Multiple-disk organizations can be used to improve the I/O performance of problems like external merging. Concurrency can be introduced by overlapping I/O requests at different disks and by prefetching additional blocks ... -
A Markov Chain Analysis of Blackjack Strategy
(2004-07-01)Blackjack receives considerable attention from mathematicians and entrepreneurs alike, due to its simple rules, its inherent random nature, and the abundance of "prior" information available to an observant player. Many ... -
A Massively Parallel Implementation of QC-LDPC Decoder on GPU
(2011-06-01)The graphics processor unit (GPU) is able to provide a low-cost and flexible software-based multi-core architecture for high performance computing. However, it is still very challenging to efficiently map the real-world ... -
Material parameter estimation and imaging with terahertz time-domain spectroscopy
(2002)Terahertz time-domain spectroscopy (THz-TDS) offers a range of unique imaging modalities due to the broad bandwidth, sub-picosecond duration, and phase-sensitive detection of the THz pulses. Previous research in the THz ... -
A Mathematical Model of the Vagally Driven SA Nodal Pacemaker
(1975-01-20)A model is developed for the vagal control of SA nodal activity in the heart and consists essentially of a modified bonhoeffer-Van der Pol (BVP) model of the "free-running" SA node and a lumped model of the neural terminations ...
