Abstract Architecture Representation Using VSPEC
(Hindawi Publishing Corporation, 1999)Complex digital systems are often decomposed into architectures very early in the design process. Unfortunately, traditional simulation based languages such as VHDL do not allow the impact of these architectural decisions ... -
Defining a formal coalgebraic semantics for the rosetta specification language
(Graz University of Technology, Institut für Informationssysteme und Computer Medien, 2003)Rosetta is a systems level design language that allows algebraic specification of systems through facets. The usual approach to formally describe a specification is to define an algebra that satisfies the specification. ... -
Optimal Prediction for Prefetching in the Worst Case
(Society for Industrial and Applied Mathematics, 2006-07-28)Response time delays caused by I/O are a major problem in many systems and database applications. Prefetching and cache replacement methods are attracting renewed attention because of their success in avoiding costly I/Os. ... -
Stereo correspondence based on curvelet decomposition, support weights, and disparity calibration
(Society of Photo-optical Instrumentation Engineers, 2010-04-13)A novel multiresolution analysis-based stereo matching method using curvelets, support weights, and disparity calibration is proposed. By introducing curvelet decomposition, we obtain the curvelet coefficients in different ... -
Compressed Suffix Arrays and Suffix Trees with Applications to Text Indexing and String Matching Read More: http://epubs.siam.org/doi/abs/10.1137/S0097539702402354
(Society for Industrial and Applied Mathematics, 2005)The proliferation of online text, such as found on the World Wide Web and in online databases, motivates the need for space-efficient text indexing methods that support fast string searching. We model this scenario as ... -
Efficient Bundle Sorting
(Society for Industrial and Applied Mathematics, 2006)Many data sets to be sorted consist of a limited number of distinct keys. Sorting such data sets can be thought of as bundling together identical keys and having the bundles placed in order; we therefore denote this as ... -

Duality Between Prefetching and Queued Writing with Parallel Disks
(Society for Industrial and Applied Mathematics, 2006-07-27)Parallel disks promise to be a cost effective means for achieving high bandwidth in applications involving massive data sets, but algorithms for parallel disks can be difficult to devise. To combat this problem, we define ... -
Optimal External Memory Interval Management
(Society for Industrial and Applied Mathematics, 2012-02-17)In this paper we present the external interval tree, an optimal external memory data structure for answering stabbing queries on a set of dynamically maintained intervals. The external interval tree can be used in an optimal ... -
Application-Controlled Paging for a Shared Cache
(Society for Industrial and Applied Mathematics, 2006-07-27)We propose a provably efficient application-controlled global strategy for organizing a cache of size k shared among P application processes. Each application has access to information about its own future page requests, ... -
Numerical Methods for Electronic Structure Calculations of Materials
(Society for Industrial and Applied Mathematics, 2010-02-05)The goal of this article is to give an overview of numerical problems encountered when determining the electronic structure of materials and the rich variety of techniques used to solve these problems. The paper is intended ... -
Circuit Elements at Optical Frequencies: Nanoinductors, Nanocapacitors, and Nanoresistors
(American Physical Society, 2005-08-23)We present the concept of circuit nanoelements in the optical domain using plasmonic and nonplasmonic nanoparticles. Three basic circuit elements, i.e., nanoinductors, nanocapacitors, and nanoresistors, are discussed in ... -
Phase noise of four‐wave mixing in semiconductor lasers
(American Institute of Physics, 1992)A simple theoreticalanalysis shows that the linewidth of the conjugate wave produced in four‐wave mixing in semiconductor lasers is equal to the linewidth of the probe plus four times the linewidth of the pump. Experimental ... -
GaN-based waveguide devices for long-wavelength optical communications
(American Institute of Physics, 2003)Refractive indices of AlxGa1−xN with different Al concentrations have been measured in infrared wavelength regions. Single-mode ridged optical waveguidedevices using GaN/AlGaN heterostructures have been designed, fabricated, ... -
Birefringence of GaN/AlGaN optical waveguides
(American Institute of Physics, 2003)We have experimentally studied the birefringence of wurtzite GaNgrown on a sapphire substrate. The measurements were done with single-mode GaN/AlGaN planar optical waveguides on c-plane grownheterostructure films. The ... -
Terahertz generation in multiple laser-induced air plasmas
(American Institute of Physics, 2008)An investigation of the terahertz wavegeneration in multiple laser-induced air plasmas is presented. First, it is demonstrated that the intensity of the terahertz wave increases as the number of air plasmas increases. ... -
Analysis of terahertz generation via nanostructure enhanced plasmonic excitations
(American Institute of Physics, 2009)In this paper, we conduct a quantitative study on the physical mechanism of electrons dynamics near the nanostructured metalfilmsurfaces, as well as the efficiency of generated terahertz radiation associated with different ... -

Towards comprehensive structural motif mining for better fold annotation in the "twilight zone" of sequence dissimilarity
(BioMed Central, 2009-01-30)Background Automatic identification of structure fingerprints from a group of diverse protein structures is challenging, especially for proteins whose divergent amino acid sequences may fall into the "twilight-" or ...
