Why Benchmarking Is An (Asymptotically) Optimal Approach To Numerical Methods: A Geombinatoric Proof, Vladik Kreinovich, Scott A. Starks
Why Benchmarking Is An (Asymptotically) Optimal Approach To Numerical Methods: A Geombinatoric Proof, Vladik Kreinovich, Scott A. Starks
Departmental Technical Reports (CS)
In numerical mathematics, one of the most frequently used ways of gauging the quality of different numerical methods is benchmarking. Specifically, once we have methods that work well on some (but not all) problems from a given problem class, we find the problem that is the toughest for the existing methods. This problem becomes a benchmark for gauging how well different methods solve problems that previous methods could not. Once we have a method that works well in solving this benchmark problem, we repeat the process again -- by selecting, as a new benchmark, a problem that is the toughest …
A Performance Study Of Lam And Mpich On An Smp Cluster, Brian Patrick Kearns
A Performance Study Of Lam And Mpich On An Smp Cluster, Brian Patrick Kearns
Dissertations and Theses
Many universities and research laboratories have developed low cost clusters, built from Commodity-Off-The-Shelf (COTS) components and running mostly free software. Research has shown that these types of systems are well-equipped to handle many problems requiring parallel processing. The primary components of clusters are hardware, networking, and system software. An important system software consideration for clusters is the choice of the message passing library.
MPI (Message Passing Interface) has arguably become the most widely used message passing library on clusters and other parallel architectures, due in part to its existence as a standard. As a standard, MPI is open for anyone …
On Clustering And Retrieval Of Video Shots Through Temporal Slices Analysis, Chong-Wah Ngo, Ting-Chuen Pong, Hong-Jiang Zhang
On Clustering And Retrieval Of Video Shots Through Temporal Slices Analysis, Chong-Wah Ngo, Ting-Chuen Pong, Hong-Jiang Zhang
Research Collection School Of Computing and Information Systems
Based on the analysis of temporal slices, we propose novel approaches for clustering and retrieval of video shots. Temporal slices are a set of two-dimensional (2-D) images extracted along the time dimension of an image volume. They encode rich set of visual patterns for similarity measure. In this paper, we first demonstrate that tensor histogram features extracted from temporal slices are suitable for motion retrieval. Subsequently, we integrate both tensor and color histograms for constructing a two-level hierarchical clustering structure. Each cluster in the top level contains shots with similar color while each cluster in bottom level consists of shots …

Motion Retrieval By Temporal Slices Analysis, Chong-Wah Ngo, Chong-Wah Ngo, Hong-Jiang Zhang
Research Collection School Of Computing and Information Systems
In this papel; we investigate video shots retrieval based on the analysis of temporal slice images. Temporal slices are a set of2D images extracted along the time dimension of image sequences. They encode rich set of motion clues for shot similarity measure. Because motion is depicted as texture orientation in temporal slices, we utilize various texture features such as tensor histogram, Gabor feature, and the statistical feature of co-occurrence matrix extracted directly from slices for motion description and retrieval. In this way, motion retrieval can be treated in a similar way as texture retrieval problem. Experimental results indicate that the …

Supervisory Control And Data Acquisition (Scada) Systems, George H. Baker, Allan Berg
George H Baker
Our critical national infrastructure systems have become almost universally dependent upon computer-based control systems technically referred to as supervisory control and data acquisition (SCADA) systems. SCADA systems evolved from the telemetry and event-alarm systems developed in the early days of utilities. With the widespread use of SCADA systems, computers have become the "basis element" for much of our critical infrastructure. Thus, the disruption of controlling computer terminals and networks due to natural disasters, electric power failure, accidents or malicious activity can have catastrophic consequences.

Simulation And Analysis Of Network Traffic For Efficient And Reliable Information Transfer, Neelima Boppana
Simulation And Analysis Of Network Traffic For Efficient And Reliable Information Transfer, Neelima Boppana
FIU Electronic Theses and Dissertations
With the growing commercial importance of the Internet and the development of new real-time, connection-oriented services like IP-telephony and electronic commerce resilience is becoming a key issue in the design of TP-based networks. Two emerging technologies, which can accomplish the task of efficient information transfer, are Multiprotocol Label Switching (MPLS) and Differentiated Services. A main benefit of MPLS is the ability to introduce traffic-engineering concepts due to its connection-oriented characteristic. With MPLS it is possible to assign different paths for packets through the network. Differentiated services divides traffic into different classes and treat them differently, especially when there is a …

Designing Interdisciplinary Approaches To Problem Solving Into Computer Languages, Daniel E. Cooke, Vladik Kreinovich, Joseph E. Urban
Designing Interdisciplinary Approaches To Problem Solving Into Computer Languages, Daniel E. Cooke, Vladik Kreinovich, Joseph E. Urban
Departmental Technical Reports (CS)
Many interdisciplinary design efforts require the involvement of computer scientists because of the complexity of the problem solving tools available for the projects. This paper demonstrates how appropriate language design can place high level languages in the hands of scientists and engineers, thus providing a more automated approach to problem solving that may reduce the amount of computer scientist involvement. The language SequenceL serves as an example of this approach.

Universal Approximation Theorem For Uninorm-Based Fuzzy Systems Modeling, Ronald R. Yager, Vladik Kreinovich
Universal Approximation Theorem For Uninorm-Based Fuzzy Systems Modeling, Ronald R. Yager, Vladik Kreinovich
Departmental Technical Reports (CS)
Most existing universal approximation results for fuzzy systems are based on the assumption that we use t-conorms and t-conorms to represent "and" and "or". Yager has proposed to use, within the fuzzy system modeling paradigm, more general operations based on uninorms. In this paper, we show that the universal approximation property holds for an arbitrary choice of a uninorm.

Absolute Bounds On The Mean Of Sum, Product, Max, And Min: A Probabilistic Extension Of Interval Arithmetic, Scott Ferson, Lev Ginzburg, Vladik Kreinovich, Jorge Lopez
Departmental Technical Reports (CS)
We extend the main formulas of interval arithmetic for different arithmetic operations x1*x2 to the case when, for each input xi, in addition to the interval [xi]=[xi-,xi+] of possible values, we also know its mean Ei (or an interval [Ei] of possible values of the mean), and we want to find the corresponding bounds for x1*x2 and its mean.

Departmental Technical Reports (CS)
Georeferencing images is a laborious process so schemes for automating this process have been under investigation for some time. Among the most promising automatic registration algorithms aare those based on Fast Fourier Transform (FFT). The displacement between the two given images can be computed by computing the ratio F1*conj(F2)/|F1*F2|, and then applying the inverse Fourier transform. The result is an impulse-like function, which is approximately zero everywhere except at the displacement that is necessary to optimally register the images. Coverting from rectangular coordinates to log-polar coordinates, shifts representing rotation and scaling can be also determined to complete the georectification process. …

Research On Advanced Soft Computing And Its Applications (Introduction To The Special Issue), Vilem Novak, Irina Perfilieva, Hung T. Nguyen, Vladik Kreinovich
Departmental Technical Reports (CS)
The main objective for the research presented in this special issue is to advance theoretical basis in soft computing, for the purpose of improving applications.
Why is this theoretical research needed? Because soft computing in general (and intelligent control and decision making in particular) are, in many aspects, still an art. To make this methodology easier to apply, we must use the experience of successful applications of fuzzy control, decision making or classification and extract formal rules that would capture this experience. To be able to do that efficiently, we must understand why some versions of soft computing methodology turned …

An Intelligent System For Monitoring The Microgravity Environment Quality On-Board The International Space Station, Paul P. Lin, Kenol Jules
Mechanical Engineering Faculty Publications
An intelligent system for monitoring the microgravity environment quality on-board the International Space Station is presented. The monitoring system uses a new approach combining Kohonen's self-organizing feature map, learning vector quantization, and a back propagation neural network to recognize and classify the known and unknown patterns. Finally, fuzzy logic is used to assess the level of confidence associated with each vibrating source activation detected by the system.
Training Radial Basis Neural Networks With The Extended Kalman Filter, Daniel J. Simon
Training Radial Basis Neural Networks With The Extended Kalman Filter, Daniel J. Simon
Electrical and Computer Engineering Faculty Publications
Radial basis function (RBF) neural networks provide attractive possibilities for solving signal processing and pattern classification problems. Several algorithms have been proposed for choosing the RBF prototypes and training the network. The selection of the RBF prototypes and the network weights can be viewed as a system identification problem. As such, this paper proposes the use of the extended Kalman filter for the learning procedure. After the user chooses how many prototypes to include in the network, the Kalman filter simultaneously solves for the prototype vectors and the weight matrix. A decoupled extended Kalman filter is then proposed in order …

Computer Science Faculty Publications and Presentations
The Law Enforcement community possesses a large, but informal, community memory with respect to digital forensics. Large, because the experiences of every forensics technician and investigator contribute to the whole. Informal because there is seldom an explicit mechanism for disseminating this wisdom except “over the water cooler”. As a consequence, the same problems and mistakes continue to resurface and the same solutions are re-invented. In order to better exploit this informal collection of wisdom, the key points of each experience can be placed into a Repository for later dissemination. We describe a web-based Lessons Learned Repository (LLR) that facilitates contribution …

Congruent Weak Conformance, Ronald W. Brower
Congruent Weak Conformance, Ronald W. Brower
Theses and Dissertations
This research addresses the problem of verifying implementations against specifications through an innovative logic approach. Congruent weak conformance, a formal relationship between agents and specifications, has been developed and proven to be a congruent partial order. This property arises from a set of relations called weak conformations. The largest, called weak conformance, is analogous to Milner's observational equivalence. Weak conformance is not an equivalence, however, but rather an ordering relation among processes. Weak conformance allows behaviors in the implementation that are unreachable in the specification. Furthermore, it exploits output concurrencies and allows interleaving of extraneous output actions in the implementation. …
