Algorithms For Adapting Materialised Views In Data Warehouses, Mukesh Mohania, Guozhu Dong
Algorithms For Adapting Materialised Views In Data Warehouses, Mukesh Mohania, Guozhu Dong
Kno.e.sis Publications
In this paper we consider the problem of materialised view adaptation in data warehouses. Materialised views are important in data warehousing where they are used to speed up query processing on large amounts of data. User requirements change over time, which may change the definitions of views dynamically. For such situations, the question arises whether the materialised views should be recomputed from scratch for every change in the definition or they should be obtained by adapting old materialised views. Changes to a view definition may be expensive, if the view is recomputed from scratch. Therefore, it is worthwhile to examine …
Gender Discourse In Small Learning Groups Of College-Level Developmental Mathematics Students, Allen W. Emerson
Gender Discourse In Small Learning Groups Of College-Level Developmental Mathematics Students, Allen W. Emerson
Dissertations
This study was motivated by the question as to whether women’s and men’s membership in different gender communicative cultures gives rise to gender differentiated ways of talking that are implicated in the failure of a mixed-sex group to achieve good mathematical discourse when women and men sit face to face engaged in various mathematical tasks. If so, in what ways and to what effect is gender discourse implicated in the failure of a mixed-sex group to achieve good mathematical discourse?
Models of feminine and masculine discourse styles based on the theory of communicative cultural difference, as well as a model …

On The Portability Of Behavioral Vhdl-93, Krishnaprasad Thirunarayan, Robert Ewing
On The Portability Of Behavioral Vhdl-93, Krishnaprasad Thirunarayan, Robert Ewing
Kno.e.sis Publications
Goossens defined a structural operational semantics for a subset of VHDL-87 and proved that the parallelism present in VHDL is benign. We extend this work to include shared variables in VHDL-93 that changes the underlying semantic model. In the presence of shared variables, non-deterministic execution of VHDL-93 processes destroys the unique meaning property. We identify and characterize a class of portable VHDL-93 descriptions for which unique meaning property can be salvaged.

Managing Multiple Information Sources Through Ontologies: Relationship Between Vocabulary Heterogeneity And Loss Of Information, Eduardo Mena, Vipul Kashyap, Arantza Illarramendi, Amit P. Sheth

The ability to deal with a huge number of independent and heterogeneous repositories is the most critical problem in Global Information Systems. One approach to enable efficient query processing is by utilizing semantic descriptions (organized as ontologies) of such repositories whenever available.
In this context semantic relationships among ontologies can be used Query Processors. Three kind of relationships are considered: synonyms and hypernyms. Using synonyms the semantic of the query is preserved; however, when synonyms are not available and hypernyms or hyponyms are used there exists some loss of information that must be measured.

The huge number of autonomous and heterogeneous data repositories accessible on the “global information infrastructure” makes it impossible for users to be aware of the locations structure/organization, query languages and semantics of the data in various repositories. There is a critical need to complement current browsing, navigational and information retrieval techniques with a strategy that focuses on information content and semantics. In any strategy that focuses on information content, the most critical problem is that of different vocabularies used to describe similar information across domains. We discuss a scalable approach for vocabulary sharing. The objects in the repositories are represented …
Proof Strategies For Hardware Verification, Robert Eastham, Krishnaprasad Thirunarayan
Proof Strategies For Hardware Verification, Robert Eastham, Krishnaprasad Thirunarayan
Kno.e.sis Publications
Ascertaining correctness of digital hardware designs through simulation does not scale-up for large designs because of the sheer combinatorics of the problem. Formal verification of hardware designs holds promise because its computational complexity is of the order of number of different types of components (and not number of components in the design). This approach requires the specification of the behavior and the design in a formal language, and reason with them using a theorem prover. In this paper we attempt to develop a methodology for writing and using these specifications for some important classes of hardware circuits. We examine digital …
Visitor Use Of Interpretive Facilities At Fossil Butte National Monument, Wyoming, Rizal Bukhari
Visitor Use Of Interpretive Facilities At Fossil Butte National Monument, Wyoming, Rizal Bukhari
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Visitors expect to a gain high-quality outdoor experiences at any recreation site they visit. In order to support that effort, most recreation managers utilize interpretive facilities to educate and inform visitors about the site. It is important for interpretive managers to be aware of what kind of interpretive media could best be used in a given setting for the type of visitor anticipated. To accomplish this goal, it is necessary to understand visitors' behavior and incorporate that understanding into the interpretive planning process.
This study looks at visitor use of interpretive facilities provided at Fossil Butte National Monument, Wyoming. The …

Semantic And Schematic Similarities Between Database Objects: A Context-Based Approach, Vipul Kashyap, Amit P. Sheth
Semantic And Schematic Similarities Between Database Objects: A Context-Based Approach, Vipul Kashyap, Amit P. Sheth
Kno.e.sis Publications
In a multidatabase system, schematic conflicts between two objects are usually of interest only when the objects have some semantic similarity. We use the concept of semantic proximity, which is essentially an abstraction/mapping between the domains of the two objects associated with the context of comparison. An explicit though partial context representation is proposed and the specificity relationship between contexts is defined. The contexts are organized as a meet semi-lattice and associated operations like the greatest lower bound are defined. The context of comparison and the type of abstractions used to relate the two objects form the basis of a …
