Preliminary Assessment Of Client Interest In And Needs Of The New England Environmental Finance Center, New England Environmental Finance Center, University Of Southern Maine Dec 2000

Preliminary Assessment Of Client Interest In And Needs Of The New England Environmental Finance Center, New England Environmental Finance Center, University Of Southern Maine

Planning

The New England Environmental Finance Center (NE/EFC) has been conceived as a knowledge-based clearinghouse, training, and change-agent program aimed at helping EPA's constituencies find financially successful approaches to environmental improvements. The NE/EFC will develop approaches to needs of particular priority in New England and potentially useful throughout the nation; share such approaches through the EFC national network; and help make tools from that network accessible throughout New England. In 1999 we began exploring with potential users how this ninth of the nation's EFCs might best address the region's needs. The assessment continued through the Muskie School's EFC proposal to EPA …

Classes Of Logic Programs Which Possess Unique Supported Models, Anthony K. Seda, Pascal Hitzler Oct 2000

Classes Of Logic Programs Which Possess Unique Supported Models, Anthony K. Seda, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Logic programming is concerned with the use of logic as a programming language. The main manifestation of this computing paradigm is in the various versions of Prolog which are now available, in which computation is viewed as deduction from sets of Horn clauses, although there is also growing interest in the related form known as answer set programming, see [10]. The reference [1] contains a good survey of the growth of logic programming over the last twenty-five years both as a stand-alone programming language and as a software component of large information systems. One advantage a logic program P has …

Environmental Finance Charette, Hyannis Park On Lewis Bay: A Case Study, New England Environmental Finance Center, Environmental Finance Center Of University Of Maryland Sep 2000

Environmental Finance Charette, Hyannis Park On Lewis Bay: A Case Study, New England Environmental Finance Center, Environmental Finance Center Of University Of Maryland

Water

The town of Yarmouth currently has a $30 million septic sludge treatment plant and transport lines in place. The vast majority of the dwellings and businesses in the Hyannis Park area are on septic systems that are viable and Title 5 compliant, regardless of age. Conventional, "non-failing" septic systems, however, were never intended to remove form their effluent nutrients such as nitrogen. These have become recognized as an environmental threat only as our understanding of the impacts of excess nutrients on ecosystems has increased in recent decades.


Semantic Web And Information Brokering: Opportunities, Commercialization, And Challenges, Amit P. Sheth Sep 2000

Semantic Web And Information Brokering: Opportunities, Commercialization, And Challenges, Amit P. Sheth

Kno.e.sis Publications

From the chairs' report published in SIGMOD record: The keynote address entitled 'Semantic Web and Information Brokering: Opportunities, Early Commercializations, and Challenges' was delivered by Amit Sheth (University of Georgia and Taalee Corp). Sheth characterized semantics as the next step in the evolution of the WWW and stressed the importance of semantically organized information for supporting ubiquitous, powerful, accurate and efficient access to this information. Sheth also reviewed proposals for semantic interoperability frameworks such as the DAML(DARPA Agent Mark-Up Language), the Oingo family of tools for defining concepts and extracting knowledge from large databases, as well as several scenarios on …


Exception Handling In Workflow Systems, Zongwei Luo, Amit P. Sheth, Krzysztof J. Kochut, John A. Miller Sep 2000

Exception Handling In Workflow Systems, Zongwei Luo, Amit P. Sheth, Krzysztof J. Kochut, John A. Miller

Kno.e.sis Publications

In this paper, defeasible workflow is proposed as a framework to support exception handling for workflow management. By using the “justified” ECA rules to capture more contexts in workflow modeling, defeasible workflow uses context dependent reasoning to enhance the exception handling capability of workflow management systems. In particular, this limits possible alternative exception handler candidates in dealing with exceptional situations. Furthermore, a case-based reasoning (CBR) mechanism with integrated human involvement is used to improve the exception handling capabilities. This involves collecting cases to capture experiences in handling exceptions, retrieving similar prior exception handling cases, and reusing the exception handling experiences …

Pattern recognition generally requires that objects be described in terms of a set of measurable features. The selection and quality of the features representing each pattern affect the success of subsequent classification. Feature extraction is the process of deriving new features from original features to reduce the cost of feature measurement, increase classifier efficiency, and allow higher accuracy. Many feature extraction techniques involve linear transformations of the original pattern vectors to new vectors of lower dimensionality. While this is useful for data visualization and classification efficiency, it does not necessarily reduce the number of features to be measured since each …


A New Fixed-Point Theorem For Logic Programming Semantics, Anthony K. Seda, Pascal Hitzler Jul 2000

A New Fixed-Point Theorem For Logic Programming Semantics, Anthony K. Seda, Pascal Hitzler

Computer Science and Engineering Faculty Publications

We present a new fixed-point theorem akin to the Banach contraction mapping theorem, but in the context of a novel notion of generalized metric space, and show how it can be applied to analyse the denotational semantics of certain logic programs. The theorem is obtained by generalizing a theorem of Priess-Crampe and Ribenboim, which grew out of applications within valuation theory, but is also inspired by a theorem of S.G. Matthews which grew out of applications to conventional programming language semantics. The class of programs to which we apply our theorem was defined previously by us in terms of operators …
