Java Performance Of The Rijndael Encryption Algorithm Across Compilers And Virtual Machines, Gregory Leavitt Orgill Jan 2005

Java Performance Of The Rijndael Encryption Algorithm Across Compilers And Virtual Machines, Gregory Leavitt Orgill

Theses and Dissertations

The Rijndael encryption algorithm has recently been published as the Advanced Encryption Standard (AES), a Federal Information Processing Standard, and is being accepted by developers and designers as the algorithm of choice where encryption is required. Java is becoming the language of choice for E-Business applications, many of which require cryptography. The performance of any Java application is dependent on the compiler and virtual machine used to compile and interpret. Prior research has provided performance information for the Rijndael algorithm in Java for specific virtual machines. This research includes the development of a Rijndael implementation in Java. Using Java system …

Simulation models were equipped with a Visual Basic interface to aid trainees to manipulate the model via ActiveX. Constructed computer simulation was compared with live simulation to answer these research questions: 1. Was computer simulation able to teach additional lean concepts not covered …


High-Throughput Inference Of Protein-Protein Interaction Sites From Unassigned Nmr Data By Analyzing Arrangements Induced By Quadratic Forms On 3-Manifolds, Ramgopal R. Mettu, Ryan H. Lilien, Bruce Randall Donald Jan 2005

High-Throughput Inference Of Protein-Protein Interaction Sites From Unassigned Nmr Data By Analyzing Arrangements Induced By Quadratic Forms On 3-Manifolds, Ramgopal R. Mettu, Ryan H. Lilien, Bruce Randall Donald

Computer Science Technical Reports

We cast the problem of identifying protein-protein interfaces, using only unassigned NMR spectra, into a geometric clustering problem. Identifying protein-protein interfaces is critical to understanding inter- and intra-cellular communication, and NMR allows the study of protein interaction in solution. However it is often the case that NMR studies of a protein complex are very time-consuming, mainly due to the bottleneck in assigning the chemical shifts, even if the apo structures of the constituent proteins are known. We study whether it is possible, in a high-throughput manner, to identify the interface region of a protein complex using only unassigned chemical shift …

A Random Rotation Perturbation Approach To Privacy Preserving Data Classification, Keke Chen, Ling Liu Jan 2005

A Random Rotation Perturbation Approach To Privacy Preserving Data Classification, Keke Chen, Ling Liu

Kno.e.sis Publications

This paper presents a random rotation perturbation approach for privacy preserving data classification. Concretely, we identify the importance of classification-specific information with respect to the loss of information factor, and present a random rotation perturbation framework for privacy preserving data classification. Our approach has two unique characteristics. First, we identify that many classification models utilize the geometric properties of datasets, which can be preserved by geometric rotation. We prove that the three types of classifiers will deliver the same performance over the rotation perturbed dataset as over the original dataset. Second, we propose a multi-column privacy model to address the …

Meteor-S Wsdi: A Scalable P2p Infrastructure Of Registries For Semantic Publication And Discovery Of Web Services, Kunal Verma, Kaarthik Sivashanmugam, Amit P. Sheth, Abhijit Patil, Swapna Oundhakar, John Miller

Kno.e.sis Publications

Web services are the new paradigm for distributed computing. They have much to offer towards interoperability of applications and integration of large scale distributed systems. To make Web services accessible to users, service providers use Web service registries to publish them. Current infrastructure of registries requires replication of all Web service publications in all Universal Business Registries. Large growth in number of Web services as well as the growth in the number of registries would make this replication impractical. In addition, the current Web service discovery mechanism is inefficient, as it does not support discovery based on the capabilities of …


Wsdl-S: Adding Semantics To Wsdl, John Miller, Kunal Verma, Preeda Rajasekaran, Amit P. Sheth, Rohit Aggarwal, Kaarthik Sivashanmugam Jan 2005

Wsdl-S: Adding Semantics To Wsdl, John Miller, Kunal Verma, Preeda Rajasekaran, Amit P. Sheth, Rohit Aggarwal, Kaarthik Sivashanmugam

Kno.e.sis Publications

Web services have primarily been designed for providing inter-operability between business applications. Current technologies assume a large amount of human interaction, for integrating two applications. This is primarily due to the fact that business process integration requires understanding of data and functions of the involved entities. Semantic Web technologies, powered by description logic based languages like OWL[1], aim to add greater meaning to Web content, by annotating the data with ontologies. Ontologies provide a mechanism of providing shared conceptualizations of domains. This allows agents to get an understanding of users’ Web content and greatly reduces human interaction for meaningful Web …


Level Mapping Characterizations Of Selector-Generated Models For Logic Programs, Sibylle Schwarz, Pascal Hitzler Jan 2005

Level Mapping Characterizations Of Selector-Generated Models For Logic Programs, Sibylle Schwarz, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Assigning semantics to logic programs via selector generated models (Schwarz 2002/2003) extends several semantics, like the stable, the inflationary, and the stable generated semantics, to programs with arbitrary formulae in rule heads and bodies. We study this approach by means of a unifying framework for characterizing different logic programming semantics using level mappings (Hitzler and Wendt 200x, Hitzler 2003), thereby supporting the claim that this framework is very flexible and applicable to very diversely defined semantics.

Taxaminer: An Experimentation Framework For Automated Taxonomy Bootstrapping, Vipul Kashyap, Cartic Ramakrishnan, Christopher Thomas, Amit P. Sheth

Kno.e.sis Publications

Construction of domain ontologies on the semantic web is a human and resource intensive process, efforts to reduce which are crucial for the Semantic Web to scale. We present a framework for automated taxonomy construction, that involves: (a) generation of a cluster hierarchy from a document corpus using statistical clustering and NLP techniques; (b) extraction of a topic hierarchy from this cluster hierarchy; and (c) assignment of labels to nodes in the topic hierarchy. Metrics for estimating topic hierarchy quality and parameters of an experimentation framework are identified. MEDLINE was the document corpus and MeSH thesaurus was the gold standard.


Ranking Complex Relationships On The Semantic Web, Boanerges Aleman-Meza, Christian Halaschek-Wiener, I. Budak Arpinar, Cartic Ramakrishnan, Amit P. Sheth Jan 2005

Ranking Complex Relationships On The Semantic Web, Boanerges Aleman-Meza, Christian Halaschek-Wiener, I. Budak Arpinar, Cartic Ramakrishnan, Amit P. Sheth

Kno.e.sis Publications

Industry and academia are both focusing their attention on information retrieval over semantic metadata extracted from the Web, and it is increasingly possible to analyze such metadata to discover interesting relationships. However, just as document ranking is a critical component in today's search engines, the ranking of complex relationships would be an important component in tomorrow's semantic Web engines. This article presents a flexible ranking approach to identify interesting and relevant relationships in the semantic Web. The authors demonstrate the scheme's effectiveness through an empirical evaluation over a real-world data set.


Variational Bayesian Image Modelling, Li Chen, Feng Jiao, Dale Schuurmans, Shaojun Wang Jan 2005

Variational Bayesian Image Modelling, Li Chen, Feng Jiao, Dale Schuurmans, Shaojun Wang

Kno.e.sis Publications

We present a variational Bayesian framework for performing inference, density estimation and model selection in a special class of graphical models—Hidden Markov Random Fields (HMRFs). HMRFs are particularly well suited to image modelling and in this paper, we apply them to the problem of image segmentation. Unfortunately, HMRFs are notoriously hard to train and use because the exact inference problems they create are intractable. Our main contribution is to introduce an efficient variational approach for performing approximate inference of the Bayesian formulation of HMRFs, which we can then apply to the density estimation and model selection problems that arise when …


How To Overcome The Knowledge Paradox: Activate Knowledge Identity, Not Just Organize Information, Sajda Qureshi, Peter Keen Jan 2005

How To Overcome The Knowledge Paradox: Activate Knowledge Identity, Not Just Organize Information, Sajda Qureshi, Peter Keen

Information Systems and Quantitative Analysis Faculty Proceedings & Presentations

A paradox appears to thwart traditional knowledge sharing efforts in organizations: the greater the benefit of a piece of knowledge to an organization the less likely that it will be shared. This paper suggests that in order to mobilize knowledge where there is demand for it, it has to be activated. This paper considers the knowledge identity of the person whose knowledge is to be activated and uses these identities to analyze a case study in which highly distributed knowledge is activated. The analysis reveals activation effects needed to mobilize each of the knowledge identities.


Framework For Semantic Web Process Composition, Kaarthik Sivashanmugam, John A. Miller, Amit P. Sheth, Kunal Verma Jan 2005

Framework For Semantic Web Process Composition, Kaarthik Sivashanmugam, John A. Miller, Amit P. Sheth, Kunal Verma

Kno.e.sis Publications

Web services have the potential to revolutionize e-commerce by enabling businesses to interact with each other on the fly. To date, however, Web processes using Web services have been created mostly at the syntactic level. Current composition standards focus on building processes based on the interface description of the participating services. This rigid approach, with its strong coupling between the process and the interface of the participating services, does not allow businesses to dynamically change partners and services. As shown in this article, Web process composition techniques can be enhanced by using semantic process templates to capture the semantic requirements …
