Generally, reliable speech recognition is a hard problem that required a combination of many techniques. Thus, the combinations of Al-Quran with speech recognition system is quite challenging task to be implemented. It is because the Quran sound, which had been recited by most of recitors will probably tend to differ a lot from one person to another. Although those Quranic sentence were particularly taken from the same verse, but the way of the sentence in Al-Quran been recited or delivered may be different, depend on recitors with the different levels of understanding of Tajweed rules. This paper seeks to provide ...
Anonymous Query Processing In Road Networks, 2010 Singapore Management University
Anonymous Query Processing In Road Networks, Kyriakos Mouratidis, Man Lung Yiu
The increasing availability of location-aware mobile devices has given rise to a flurry of location-based services (LBSs). Due to the nature of spatial queries, an LBS needs the user position in order to process her requests. On the other hand, revealing exact user locations to a (potentially untrusted) LBS may pinpoint their identities and breach their privacy. To address this issue, spatial anonymity techniques obfuscate user locations, forwarding to the LBS a sufficiently large region instead. Existing methods explicitly target processing in the euclidean space and do not apply when proximity to the users is defined according to network distance ...
Continuous Monitoring Of Spatial Queries In Wireless Broadcast Environments, 2010 Singapore Management University
Continuous Monitoring Of Spatial Queries In Wireless Broadcast Environments, Kyriakos Mouratidis, Spiridon Bakiras, Dimitris Papadias
Wireless data broadcast is a promising technique for information dissemination that leverages the computational capabilities of the mobile devices in order to enhance the scalability of the system. Under this environment, the data are continuously broadcast by the server, interleaved with some indexing information for query processing. Clients may then tune in the broadcast channel and process their queries locally without contacting the server. Previous work on spatial query processing for wireless broadcast systems has only considered snapshot queries over static data. In this paper, we propose an air indexing framework that 1) outperforms the existing (i.e., snapshot) techniques ...
Theory And Applications Of Compressive Sensing, 2010 Electrical and Computer Engineering, Purdue University
Theory And Applications Of Compressive Sensing, Atul Divekar, Okan Ersoy
Department of Electrical and Computer Engineering Technical Reports
This thesis develops algorithms and applications for compressive sensing, a topic in signal processing that allows reconstruction of a signal from a limited number of linear combinations of the signal. New algorithms are described for common remote sensing problems including superresolution and fusion of images. The algorithms show superior results in comparison with conventional methods. We describe a method that uses compressive sensing to reduce the size of image databases used for content based image retrieval. The thesis also describes an improved estimator that enhances the performance of Matching Pursuit type algorithms, several variants of which have been developed for ...
Multi-Modular Integral Pressurized Water Reactor Control And Operational Reconfiguration For A Flow Control Loop, 2010 University of Tennessee - Knoxville
Multi-Modular Integral Pressurized Water Reactor Control And Operational Reconfiguration For A Flow Control Loop, Sergio Ricardo Pereira Perillo
This dissertation focused on the IRIS design since this will likely be one of the designs of choice for future deployment in the U.S and developing countries. With a net 335 MWe output IRIS novel design falls in the “medium” size category and it is a potential candidate for the so called modular reactors, which may be appropriate for base load electricity generation, especially in regions with smaller electricity grids, but especially well suited for more specialized non-electrical energy applications such as district heating and process steam for desalination. The first objective of this dissertation is to evaluate and ...

Data Routing In Multicore Processors Using Dimension Increment Method, Arpita H. Kadakia
UNLV Theses, Dissertations, Professional Papers, and Capstones
A Deadlock-free routing algorithm can be generated for arbitrary interconnection network using the concept of virtual channels but the virtual channels will lead to more complex algorithms and more demands of NOC resource.
In this thesis, we study a Torus topology for NOC application, design its structure and propose a routing algorithm exploiting the characteristics of NOC. We have chosen a typical 16 (4 by 4) routers Torus and propose the corresponding route algorithm. In our algorithm, all the channels are assigned 4 different dimensions (n0,n1,n2 & n3). By following the dimension increment method, we break the dependent route ...

An Incremental Multilinear System For Human Face Learning And Recognition, 2010 Florida International University
An Incremental Multilinear System For Human Face Learning And Recognition, Jin Wang
FIU Electronic Theses and Dissertations
This dissertation establishes a novel system for human face learning and recognition based on incremental multilinear Principal Component Analysis (PCA). Most of the existing face recognition systems need training data during the learning process. The system as proposed in this dissertation utilizes an unsupervised or weakly supervised learning approach, in which the learning phase requires a minimal amount of training data. It also overcomes the inability of traditional systems to adapt to the testing phase as the decision process for the newly acquired images continues to rely on that same old training data set. Consequently when a new training set ...

Uwb-Fsk: Performance Tradeoffs For High And Low Complexity Receivers, Todor Cooklev, Fernando Ramirez-Mireles, G. A. Paredes-Orozco
Engineering Faculty Publications
In this work we explore flexible modulations toallow demodulation using receivers with different complexityand cost. More specifically, we study pulse-based ultrawideband (UWB) communications over channels with densemultipath effects using frequency shift keying (FSK) datamodulation. Our aim is to explore the performance tradeoffsbetween high and low complexity receivers. For this purposewe determine the performance of coherent, non-coherent andmismatched (e.g., non-coherent detection using templatesconsisting of a single path) demodulators. We take intoaccount the influence of the frequency response of the antennasystem and the effects of the frequency selectivity of themultipath channel. Given a specific channel condition, wederive expressions for the bit ...
Wavelet Based Islanding Detection Of Dc-Ac Inverter Interfaced Dg Systems, 2010 Dublin Institute of Technology
Wavelet Based Islanding Detection Of Dc-Ac Inverter Interfaced Dg Systems, Mohamed Moin Hanif, Malabika Basu, Kevin Gaughan
The increased penetration of distributed generation (DG) often connected to grid through dc-ac interface has made islanding detection an important and challenging issue to power engineers. Several methods based on passive and active detection scheme have been proposed in the literature. While passive schemes have a large non detection zone (NDZ), concern has been raised on active method due to its degrading power quality effect. This paper proposes a wavelet based passive islanding detection scheme with almost zero NDZ for dc-ac inverter interfaced grid connected DGs. The key idea is to utilize the spectral changes in the higher frequency components ...
Multi-Frequency Processing For Lumen Enhancement With Wideband Intravascular Ultrasound, 2010 California Polytechnic State University - San Luis Obispo
Multi-Frequency Processing For Lumen Enhancement With Wideband Intravascular Ultrasound, Rory A. Carrillo
Master's Theses and Project Reports
The application of high frequency ultrasound is the key to higher resolution intravascular ultrasound (IVUS) images. The need to further improve the IVUS spatial resolution may drive the transducer center frequency even higher than the current 40 MHz range. However, increasing the center frequency may be challenging as it leads to stronger scattering echoes from blood. The high level of blood scattering echoes may obscure the arterial lumen and make image interpretation difficult. Blood backscatter levels increase with transmission center frequency at a much greater rate compared to arterial tissue. These different frequency dependencies provide a potential method to distinguish ...
Enhanced High-Resolution Imaging Through Multiple-Frequency Coarray Augmentation, 2010 University of Pennsylvania
Enhanced High-Resolution Imaging Through Multiple-Frequency Coarray Augmentation, Jeannie L. Moulton
Publicly Accessible Penn Dissertations
In imaging, much attention is paid to increasing the resolution capabilities of a system. Increasing resolution allows for high-accuracy source location and the ability to discriminate between two closely-spaced objects. In conventional narrowband techniques, resolution is fundamentally limited by the size of the aperture. For apertures consisting of individual elements, direction-of-arrival techniques allow for high-resolution images of point sources. The main limiting factor on conventional high-resolution imaging is the number of elements in the aperture. For both passive and active imaging, to resolve K point sources/targets, there must be at least K+1 elements receiving radiation. In active imaging ...
Application Of Signal Advance Technology To Electrophysiology, 2010 University of Texas Graduate School of Biomedical Sciences at Houston
Application Of Signal Advance Technology To Electrophysiology, Chris M. Hymel
UT GSBS Dissertations and Theses (Open Access)
Medical instrumentation used in diagnosis and treatment relies on the accurate detection and processing of various physiological events and signals. While signal detection technology has improved greatly in recent years, there remain inherent delays in signal detection/ processing. These delays may have significant negative clinical consequences during various pathophysiological events. Reducing or eliminating such delays would increase the ability to provide successful early intervention in certain disorders thereby increasing the efficacy of treatment.
In recent years, a physical phenomenon referred to as Negative Group Delay (NGD), demonstrated in simple electronic circuits, has been shown to temporally advance the detection of ...

Scan Loss Pattern Synthesis For Adaptive Array Ground Stations, 2010 Embry-Riddle Aeronautical University
Scan Loss Pattern Synthesis For Adaptive Array Ground Stations, William C. Barott, Mary Ann Ingram, Paul G. Steffes
We present several techniques for maximizing the contact time between low Earth orbiting satellites (LEOs) and a ground station (GS). The GS comprises an adaptive array of electronically steered space-fed lenses (SFLs). Each SFL is manufactured as a low-cost printed circuit with the result that it exhibits scanning loss. By differently orienting the boresights of the SFLs in the adaptive array, the SFL's scanning losses can be made to optimally complement the path loss of the LEO, thereby reducing the cost of the GS while maximizing the download capacity of the satellite link. The optimization, implemented with a genetic ...
Intelligibility Of Electrolarynx Speech Using A Novel Actuator, 2010 Dublin Institute of Technology
Intelligibility Of Electrolarynx Speech Using A Novel Actuator, Brian Madden, Mark Nolan, Ted Burke, James Condron, Eugene Coyle
During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. Following a laryngectomy, some people speak using an electrolarynx which replaces the excitatory function of the absent larynx. Drawbacks of conventional electrolarynx designs include the buzzing monotonic sound emitted, the need for a free hand to operate the device, and difficulty experienced by many laryngectomees in adapting to its use. Despite these shortcomings, it remains the preferred method of speech rehabilitation for a substantial minority of laryngectomees. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal ...

There is a significant demand for a decreasein the size, weight and power (SWaP) associated withwireless systems. In this research, a low-complexityMIMO OFDM system is advanced. The proposedsystem is essentially multiplierless and thus requiresmuch simpler digital hardware to be implemented. As aresult, the chip area associated with the MIMO OFDMsystem can be significantly reduced. The reduction incomplexity is obtained via modification to the FastFourier Transform (FFT) and Inverse Fast FourierTransform (IFFT) algorithms necessary to implementOFDM multi-carrier modulation. Computationalcomplexity is reduced by quantizing what are known asthe “twiddle factors” in traditional FFT algorithms suchas the Radix-4. The quantization allows for allmultiplications ...
