Twinscan: A Software Package For Homology-Based Gene Prediction, Paul Flicek

All Computer Science and Engineering Research

A complete mapping from genome to proteome would constitute a foundation for genome-based biology and provide targets for pharmaceutical and therapeutic intervention. This is one reason gene structure prediction has been a major subfield of computational biology for over 20 years. Many of the widely used gene prediction systems were developed in the 1990s and are unable to take advantage of the revolution in comparative genomics brought on by the sequencing of the entire genomes of an increasing numbers of vertebrates. Twinscan is a new system for high-throughput gene-structure prediction that exploits the patterns of conservation observed in alignments between …

Statistical And Dempster-Shafer Techniques In Testing Structural Integrity Of Aerospace Structures, Roberto A. Osegueda, Seetharami R. Seelam, Bharat Mulupuru, Vladik Kreinovich

Departmental Technical Reports (CS)

Several techniques are known for non-destructive testing of aerospace structures, such as pulse echo, Eddy current, magnetic resonance, etc. Each of these techniques detects some faults but misses others, so it is desirable to combine (fuse) the results of these techniques. Several methods of data fusion are known. To improve the quality of fault detection, we modified the straightforward statistical method as follows: (1) we computed mean and variance iteratively: detected faults are excluded form the computation on the next iteration; (2) we treated the plate's edge and the inside separately; (3) we dismissed measurements in which only one technique …

A New Cauchy-Based Black-Box Technique For Uncertainty In Risk Analysis, Vladik Kreinovich, Scott Ferson

Departmental Technical Reports (CS)

Uncertainty is very important in risk analysis. A natural way to describe this uncertainty is to describe a set of possible values of each unknown quantity (this set is usually an interval), plus any additional information that we may have about the probability of different values within this set. Traditional statistical techniques deal with the situations in which we have a complete information about the probabilities; in real life, however, we often have only partial information about them. We therefore need to describe methods of handling such partial information in risk analysis. Several such techniques have been presented, often on …

Detection Of Cracks At Rivet Holes In Thin Plates Using Lamb-Wave Scanning, Roberto A. Osegueda, Vladik Kreinovich, Soheil Nazarian, Enrique Roldan

Departmental Technical Reports (CS)

This paper describes a Lamb-wave scanning method for the detection of notches simulating cracks at rivet holes in thin plates. The approach requires the generation of an ultrasonic So-Mode Lamb wave using an incident transmitter excited with a tone burst centered at a near non-dispersive frequency. Area scans are performed of a plate with a hole with a notch to generate times series information which is used to create animations illustrating the wave propagation characteristics. The time series are subject to a sifting process to obtain intrinsic mode functions which contain narrow frequency banded information of the signals. The Hilbert-Huang …

Storage Allocation In Bounded Time, Sharath Reddy Cholleti

All Computer Science and Engineering Research

The correctness of a real-time system is very much dependent on the time at which a specific task is completed. Hence, satisfying a storage allocation request within bounded time is important. Fragmentation of the heap after repeated allocations and deallocations is a major issue for real-time systems, as most allocators depend on garbage collection for defragmentation of the heap, which might not finish in time to honor deadlines. We present the storage requirement for a defragmentation-free binary-buddy allocator. We also study a localized defragmentation algorithm to satisfy a single allocation request, within bounded time, instead of requiring defragmentation of the …

Evaluation Of Intrusion Detection Systems With Automatic Traffic Generation Programs, Friday Bassey Akpan

Theses

In this master's thesis work, a program was developed using the Perl programming language to enable user defined attack programs to run automatically. A similar program was also developed for background traffic. With this program, the different features of the Nmap exploration and scanning tool were exploited to build scenarios of attacks.

Automated scenarios of attacks running in to the order of hundreds were developed. Also, different sets of automated stealthy attacks scenarios running in to the order of hundreds were developed using the timing modes, stealthy scans and scan delay features of Nmap.

These automated attacks scenarios were employed …

The Design And Performance Of Special Purpose Middleware: A Sensor Networks Case Study, Venkita Subramonian, Guoliang Xing, Christopher Gill, Ron Cytron

All Computer Science and Engineering Research

General purpose middleware has been shown to be effective in meeting diverse functional requirements for a wide range of distributed systems. Advanced middleware projects have also supported a single quality-of-service dimension such as real-time, fault tolerance, or small memory footprint. However, there is limited experience supporting multiple quality-of-service dimensions in mid-dleware to meet the needs of special purpose applications. Even though general purpose middleware can cover an entire spectrum of applications by supporting the union of all features required by each application, this approach breaks down for distributed real-time and embedded systems. In particular, features from one dimension such as …

Complexity Of Single-Agent And Equilibrium-Based Multiagent Planning And Plan Checking: Approach When We Have A List Of Valid States, Chitta Baral, Vladik Kreinovich

Departmental Technical Reports (CS)

In a recent paper M. Bowling, R. Jensen, and M. Veloso proposed a new formalization of the problem of multiagent planning - a formalization that is based on the (intuitively natural) notion of an equilibrium. In this paper we analyze the computational complexity of the corresponding equilibrium-based multiagent planning and plan checking. Within the traditional approach in which states are described by fluents, the computational complexity of planning under incompleteness is PSPACE-hard already for a single agent; therefore, to make a meaningful comparison between the complexity of single-agent and multi-agent planning, we analyze complexity in a different approach, in which …

Managing Content-Initiated Application Delivery With A Client-Side Agent, Niall Roche, Gary Clynch

Conference Papers

Mobile devices have evolved with improvements in processing power and support for various application environments such as MExE [1]. Currently a large number of devices and platforms exist, each with various attributes. Such diversity results in problems providing appropriate applications to these devices. This paper outlines need for an integrated approach to application delivery for mobile devices. The solution allows suitable applications to be delivered to devices. Application management is removed from non-technical mobile device users through the presence of a client-side agent to manage the complexity of application provisioning, device resource management and application management.

Common Data Administration, Data Management, And Data Alignment As A Necessary Requirement For Coupling C4isr Systems And M&S Systems, Andreas Tolk

Computational Modeling & Simulation Engineering Faculty Publications

Within the application domain of military simulation systems, training and exercises as well as support to real operations require the coupling of the simulation system delivering the needed functionality with the Command, Control, Computing, Communications, Intelligence, Surveillance, and Reconnaissance (C4ISR) system providing the necessary data. The solution to this challenge is to build appropriate interfaces. Although in long term a more integrated approach will be necessary, in short and mid term, gateways and interfaces are likely to remain the standard. However, in order to succeed with the respective efforts, at least on the data level of interoperability, a common solution …

Towards Foundations Of Processing Imprecise Data: From Traditional Statistical Techniques Of Processing Crisp Data To Statistical Processing Of Fuzzy Data, Hung T. Nguyen, Tonghui Wang, Vladik Kreinovich

Departmental Technical Reports (CS)

In traditional statistics, we process crisp data - usually, results of measurements and/or observations. Not all the knowledge comes from measurements and observations. In many real-life situations, in addition to the results of measurements and observations, we have expert estimates, estimates that are often formulated in terms of natural language, like "x is large". Before we analyze how to process these statements, we must be able to translate them in a language that a computer can understand. This translation of expert statements from natural language into a precise language of numbers is one of the main original objectives of fuzzy …

Rhythmic Parsing Of Sonified Dna And Rna Sequences, Charlie Cullen, Eugene Coyle

Conference papers

Sonification allows existing mathematical data to be used as the model for audio output, notably that the audio produced is related to or representative of that data in some way. Existing work in the field has been largely focused on the aesthetic tailoring of the output audio for compositional benefit rather than as a framework for audio representation and analysis. It is the goal of this research to apply existing techniques for pitch substitution to an analytical method that seeks to define and represent patterns within existing data sets (primarily DNA and RNA sequences). It is often the case that …

A Performance Study Of Dynamic Zone Topology Routing Protocol, Mehran Abolhasan, Tadeusz A. Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

In this paper we present a simulation study of a hybrid routing protocol we proposed in our previous work. Our hybrid routing strategy is called Dynamic Zone Topology Routing protocol (DZTR). This protocol has been designed to provide scalable routing in a Mobile Ad hoc Networking (MANET) environment. DZTR breaks the network into a number of zones by using a GPS. The topology of each zone is maintained proactively and the route to the nodes in other zones are determined reactively. DZTR proposes a number of different strategies to reduce routing overhead in large networks and reduce the single point …

Increasing Performance Of Sqrd Decoding For Lst Systems, Phillip Conder, Tadeusz A. Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

A number of decoding schemes have been proposed for Layered Space-Time systems, such as the Ordered Successive Interference Cancellation and the Sorted QR Decomposition. We describe here a new addition to that group, increasing the performance of Layered Space-Time decoding by using the Sorted QR Decomposition technique to construct a list of constellations to be passed to a Maximum Likelihood decoder. This paper shows that signifcant performance improvement can be obtained for symmetric systems, where there is an equal number of transmit and receive antennas. It shows that the proposed scheme, has a roughly linear increase in complexity compared to …

On The Effect Of Adjacent Sector Multiple Access Interference On Space Time Spreading Systems, Peter Vial, Ibrahim Raad, Tadeusz A. Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

Space Time Spreading systems are proposed as a method to enhance communications between the Base Station (BS) and Mobile Station (MS) by using multiple transmit antennas at the Base Station. This provides a form of transmit diversity when there are more than one transmitting antennas. Space Time Spreading systems have been shown to be efficient in their use of the limited number of orthogonal spreading sequences and to provide a diversity gain, which in the case of two transmitter antennas at the BS and one receiving antenna at the MS, is of order two. The paper looks at the effect …

An Interaction Initiative Model For Documentation, David G. Novick, Karen Ward

Departmental Papers (CS)

In this paper we propose a model of creation and use of documentation based on the concept of mixed-initiative interaction. In our model, successful single-initiative interaction is characterized by grounding of contributions, and successful mixed-initiative interaction is characterized by both grounding and agreement. Just as in spoken conversation, achievement of actual agreement depends on the intentions of both parties; agreement is achieved when the reader follows the documentation’s instructions. In fact, readers are not obligated to—and often do not—act according to the author’s intentions. By making these dynamics explicit, the model can aid authors in developing effective documentation. The paper …

Hands-Free Documentation, Karen Ward, David G. Novick

Departmental Papers (CS)

In this paper, we introduce an analysis of the requirements and design choices for hands-free documentation. Hands-busy tasks such as cooking or car repair may require substantial interruption of the task: moving the pan off the burner and wiping hands, or crawling out from underneath the car. We review the need for hands-free documentation and explore the role of task in the use of documentation. Our central analysis examines the roles and characteristics of input and output modalities of hands-free documentation. In particular, we review the use of speech as an input modality, and then visual means and speech as …

Parametrically Tunable Audio Shelving And Equalizing Ladder Wave Digital Filters, S. A. Samad

Turkish Journal of Electrical Engineering and Computer Sciences

Parametrically tunable audio equalizers are conventionally realized using allpass digital filter networks. They consist of first-order shelving filters and second-order equalizing filters. In this paper, ladder wave digital filters (WDFs) with parametrically tunable coefficients are proposed as shelving and equalizing filters. Similar to the allpass realization, the transfer function power complementary property of WDFs is used to obtain efficient shelving and equalizing filters. However, unlike the allpass structures, the transfer function and the tunable parameters of the ladder WDF are derived from the analog filter equivalent of the digital shelving and equalizing filters. For the shelving WDF, the cut-off frequency …
