Algorithms For Adapting Materialised Views In Data Warehouses, Mukesh Mohania, Guozhu Dong Dec 1996

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 ...


On The Portability Of Behavioral Vhdl-93, Krishnaprasad Thirunarayan, Robert Ewing Oct 1996

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.


Perspectives On The Use Of Internet In Art Classrooms, Donalyn Heise, Neal Grandgenett Oct 1996

Perspectives On The Use Of Internet In Art Classrooms, Donalyn Heise, Neal Grandgenett

Teacher Education Faculty Publications

With the emergence of Internet technology, students have the opportunity to develop skills necessary to live, work and play in the 21st century. More than ever before, students will need to be competent in accessing and managing information from a variety of sources. The Internet allows students to engage in global communication, as well as access the most current information available. For art education, the Internet also provides a real opportunity to blend multicultural, multi-age, gender-inclusive educational reform into the art curriculum by incorporating visual resources and contextual information from many different cultures.


Managing Multiple Information Sources Through Ontologies: Relationship Between Vocabulary Heterogeneity And Loss Of Information, Eduardo Mena, Vipul Kashyap, Arantza Illarramendi, Amit P. Sheth Aug 1996

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

Kno.e.sis Publications

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.


Observer: An Approach For Query Processing In Global Information Systems Based On Interoperation Across Pre-Existing Ontologies, Eduardo Mena, Vipul Kashyap, Amit P. Sheth, Arantza Illarramendi Jun 1996

Observer: An Approach For Query Processing In Global Information Systems Based On Interoperation Across Pre-Existing Ontologies, Eduardo Mena, Vipul Kashyap, Amit P. Sheth, Arantza Illarramendi

Kno.e.sis Publications

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 ...

Proof Strategies For Hardware Verification, Robert Eastham, Krishnaprasad Thirunarayan May 1996

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 ...

Beads Among The Juang Of India, Alok Kumar Kanungo Jan 1996

Beads Among The Juang Of India, Alok Kumar Kanungo

BEADS: Journal of the Society of Bead Researchers

The Juang comprise a major primitive community in the state of Orissa in east-central India. Until relatively recently, they had a rich material culture. In particular, their dress and ornaments were very important to them. Today, only very old women wear beads and other ornaments in the traditional way, except on special occasions. This paper seeks to reconstruct the traditional costume of the Juang, with emphasis on the beads, and notes the changes it has undergone over the past 130 years. The findings are based on a survey of the ethnohistoric literature combined with active participant fieldwork in 1995 and ...


Akyem Te: The Technology And Socio-Cultural Setting Of The Abompe Bauxite-Beadmaking Industry, Ghana, Yaw Bredwa-Mensah Jan 1996

Akyem Te: The Technology And Socio-Cultural Setting Of The Abompe Bauxite-Beadmaking Industry, Ghana, Yaw Bredwa-Mensah

BEADS: Journal of the Society of Bead Researchers

Drawing primarily on data obtained from recent research at Akyem Abompe, Ghana, this paper examines the technology and socio-cultural setting of a stone-beadmaking industry in the forest zone of Ghana. Preliminary ethnographic observation of the industry not only reveals that it is community-based, but that it also interacts in a complex way with other local crafts in the village. The production process and marketing of the beads are discussed, as is the antiquity of the industry.


Imitation Pearls In France, Marie-José Opper, Howard Opper Jan 1996

Imitation Pearls In France, Marie-José Opper, Howard Opper

BEADS: Journal of the Society of Bead Researchers

To achieve the perfect imitation pearl has been the goal of numerous European beadmakers for over 700 years. In France, the art of making false-pearls spread rapidly after Jacquin discovered how to fill hollow glass beads with a pearl-like substance in the 17th century. Since that time, many diverse recipes have been tried and used to satisfy the French public's enormous appetite for affordable, yet elegant, imitations of fine pearls. In the 19th and early 20th centuries, these types of beads became even more popular than before, as they emerged as the principal components of costume jewelry worn by ...


A Hoard Of Stone Beads Near Lake Chad, Nigeria, Graham Connah Jan 1996

A Hoard Of Stone Beads Near Lake Chad, Nigeria, Graham Connah

BEADS: Journal of the Society of Bead Researchers

In 1980, a small pot containing 622 carnelian and quartz beads was found accidentally at Ala, in the Nigerian part of the clay plain south of Lake Chad. It appears to constitute a hoard of wealth which its owner buried and subsequently failed to retrieve. Beads of this sort first appear in this area in the second half of the first millennium A.D., but also occur in second-millennium deposits. However, they are usually found as grave goods, and the Ala discovery is almost the only example of a hoard of such beads known to the author. Their presence on ...

Rising Temperatures: Rising Tides, Prof. Elizabeth Burleson

Prof. Elizabeth Burleson

Transboundary environmental problems do not distinguish between political boundaries. Global warming is expected to cause thermal expansion of water and melt glaciers. Both are predicted to lead to a rise in sea level. We must enlarge our paradigms to encompass a global reality and reliance upon global participation.


Beads, Pendants And Buttons From Early Historic Creek Contexts At The Tarver Sites, Georgia, Thomas J. Pluckhahn Jan 1996

Beads, Pendants And Buttons From Early Historic Creek Contexts At The Tarver Sites, Georgia, Thomas J. Pluckhahn

BEADS: Journal of the Society of Bead Researchers

Recent excavations conducted on historic Creek Indian components at the Tarver (9JO6) and Little Tarver (9JO198) sites in central Georgia produced an extensive collection of European trade material, including a large sample of glass and lapidary beads, pendants and buttons. The bead collection is significant for its size, as well as the fact that virtually all of the material was recovered from undisturbed and tightly dated burial contexts attributable to the relatively brief period between about 1695 and 1715.


Semantic And Schematic Similarities Between Database Objects: A Context-Based Approach, Vipul Kashyap, Amit P. Sheth Jan 1996

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 ...

Geological And Land Instability Mapping Using A Gis Package As A Building Block For The Development Of A Risk Assessment Procedure, R N. Chowdhury, P N. Flentje Jan 1996

Geological And Land Instability Mapping Using A Gis Package As A Building Block For The Development Of A Risk Assessment Procedure, R N. Chowdhury, P N. Flentje

Faculty of Engineering and Information Sciences - Papers: Part A

A modern land instability risk assessment procedure must include an accurate geological framework and land instability database. Geological and land instability mapping of the northern suburbs of the City of Wollongong represents a considerable challenge and is to be achieved using computer generated 1:4000 topographic base maps. Using an integrated series of techniques, including computer modelling of the escarpment geology and field mapping techniques, a new series of geological maps has been produced. Meanwhile an exhaustive land instability database of the region has been compiled. A flexible approach to mapping and data compilation is very useful and confirms the ...

Far-Infrared Measurements Of Cyclotron Resonance And Impurity Transitions In Bulk N-Gaas In Pulsed Magnetic Fields, R A. Lewis, R J. Heron, R G. Clark, R P. Starrett, A V. Skougarevsky

Faculty of Engineering and Information Sciences - Papers: Part A

The photoconductive response of n-GaAs has been measured under laser radiation in the wavelength range 71 to 513 /spl mu/m at temperatures as low as 400 mK and at magnetic fields as high as 42 T. A rich variety of spectral features are observed: cyclotron resonance, transitions associated with D/sup -/, and transitions to stable and metastable hydrogenic states. The use of a pulsed magnet has extended the magnetic field range over which data is available by a factor of three.
