The "Infoharness" Information Integration Platform, Leon Shklar, Satish Thatte, Howard Marcus, Amit P. Sheth Oct 1994

The "Infoharness" Information Integration Platform, Leon Shklar, Satish Thatte, Howard Marcus, Amit P. Sheth

Kno.e.sis Publications

The "InfoHarness" information integration platform, tools, and services being developed at Bellcore are aimed at providing integrated and rapid access to huge amounts of heterogeneous information independent of the type, representation, and location of information. InfoHarness provides advanced search and browsing capabilities without imposing the burden of restructuring, reformatting or relocating information on information suppliers or creators. This is achieved through object-oriented encapsulation of information and the associated meta-information (e.g., type, location, access rights, owner, creation date, etc.). The meta-information extraction methods ensure rapid and largely automatic creation of information repositories. A gateway that supports access to InfoHarness repositories ...

Using Tickets To Enforce The Serializability Of Multidatabase Transactions, Dimitrios Georgakopoulos, Marek Rusinkiewicz, Amit P. Sheth Feb 1994

Using Tickets To Enforce The Serializability Of Multidatabase Transactions, Dimitrios Georgakopoulos, Marek Rusinkiewicz, Amit P. Sheth

Kno.e.sis Publications

To enforce global serializability in a multidatabase environment the multidatabase transaction manager must take into account the indirect (transitive) conflicts between multidatabase transactions caused by local transactions. Such conflicts are difficult to resolve because the behavior or even the existence of local transactions is not known to the multidatabase system. To overcome these difficulties, we propose to incorporate additional data manipulation operations in the subtransactions of each multidatabase transaction. We show that if these operations create direct conflicts between subtransactions at each participating local database system, indirect conflicts can be resolved even if the multidatabase system is not aware of ...

Beads From The African Burial Ground, New York City: A Preliminary Assessment, Cheryl J. Laroche Jan 1994

Beads From The African Burial Ground, New York City: A Preliminary Assessment, Cheryl J. Laroche

BEADS: Journal of the Society of Bead Researchers

Excavation of the African Burial Ground in New York City yielded the skeletal remains of more than 400 individuals. This paper is a preliminary discussion of beads associated with seven of the burials. The in situ bead configurations of three of the interments are distinctive and appear to be indicative of cultural practices of Africans in 18th-century New York. The configurations include necklaces and possibly wristlets, as well as waistbeads. The latter represent the first recorded instance of such use by Africans or African descendants in North America. These objects provide insight into the religious or ritual behavior of the ...


Toward A Social History Of Beadmakers, Peter Francis Jr. Jan 1994

Toward A Social History Of Beadmakers, Peter Francis Jr.

BEADS: Journal of the Society of Bead Researchers

An understanding of beads requires an understanding of the people involved with them. This paper examines three historical aspects of people engaged in beadmaking, especially the production of glass beads. The history of their social relations is considered in regards to the record of their physical movements, the manner in which they organize themselves and pass on their traditions, and their status within society. Information concerning each of these is arranged geographically and chronologically in an attempt to discern the patterns of the social history of beadmakers.

European Beads From Spanish-Colonial Lamanai And Tipu, Belize, Marvin T. Smith, Elizabeth Graham, David M. Pendergast Jan 1994

European Beads From Spanish-Colonial Lamanai And Tipu, Belize, Marvin T. Smith, Elizabeth Graham, David M. Pendergast

BEADS: Journal of the Society of Bead Researchers

Excavation of the contact-period components of the Maya sites of Lamanai and Tipu, in northern and west-central Belize, respectively, have yielded moderate collections of European glass and other beads. The archaeological data are augmented by ethnohistorical documentation regarding the length of Maya/Spanish interaction. Contexts do not provide unequivocal stratigraphic evidence of sequential bead importation, but known dates of bead varieties assist in refining both site chronology and the understanding of bead use. As the first Central American collections to be analyzed, the two assemblages offer an initial glimpse of one aspect of European impact on native material and non-material ...

A Possible Beadmaker's Kit From North America's Lake Superior Copper District, Susan R. Martin Jan 1994

A Possible Beadmaker's Kit From North America's Lake Superior Copper District, Susan R. Martin

BEADS: Journal of the Society of Bead Researchers

Beads of copper are amongst the oldest and most widespread ornament forms known in North America. Native copper was an important material to prehistoric Americans, and certainly the most important metal. It was collected, transported and traded over wide areas from as early as seven thousand years before present, and its for ornaments persisted until it was gradually replaced by European metals over the many years of the contact period. A recently discovered cache of copper beads, bead preforms, awls, a crescent knife and scraps of raw copper at site 20KE20 in northern Michigan offers insight into the process of ...


The Strong Relevance Logics, Martin W. Bunder Jan 1994

The Strong Relevance Logics, Martin W. Bunder

Faculty of Engineering and Information Sciences - Papers: Part A

The tautology p - q - p is not a theorem of the various relevance logics (see Anderson and Belnap [1]) because q is not considered to be relevant in the derivation of final p. We can take this lack of relevance to mean simply that p-q-p could have been proved without q and its -, i.e., p-p. By the same criterion we could say that in ((p-p) -q) -q p-p is not relevant. In general we will say that any theorem A of an implicational logic is strongly relevant if there is no subpart B ! which can be removed from A ...

The Interpretation Of Laser Sensing Measurements For Blast Furnace Operations And Control, Peter C. Wall, R J Turner, Mark Hughes, Peter Huk, Ross J. Haywood, M J Mccarthy, Paul Zulli Jan 1994

The Interpretation Of Laser Sensing Measurements For Blast Furnace Operations And Control, Peter C. Wall, R J Turner, Mark Hughes, Peter Huk, Ross J. Haywood, M J Mccarthy, Paul Zulli

Faculty of Engineering and Information Sciences - Papers: Part A

Several laser-based sensors for use on blast furnaces have been developed and implemented, including a raceway sensor, burden level sensor (single point) and burden surface profiler. These sensors are based on the time-of-flight technique and give high levels of accuracy in all applications. The data obtained from the sensors during normal furnace operations are examined in light of the process models utilised by operators and for the interpretation of pulverised coal injection performance. Raceway sensory data obtained during a furnace blow-in are also discussed.


Low Temperature Synthesis Of Al-Aln Composites From A Nanostructure Made By Controlled Magneto-Ball Milling Of Al In Ammonia, Andrzej Calka, J I. Nikolov, G H. J Wantenaar Jan 1994

Low Temperature Synthesis Of Al-Aln Composites From A Nanostructure Made By Controlled Magneto-Ball Milling Of Al In Ammonia, Andrzej Calka, J I. Nikolov, G H. J Wantenaar

Faculty of Engineering and Information Sciences - Papers: Part A

The formation of an AlN compound in ball milled Al powder in ammonia was studied. In this work a magneto‐ball milling device with controlled ball movement was used. The end milling product was an Al based nanostructure. This product can be transformed into an AlN‐Al nanocomposite upon heating below the melting point of Al. It was found that the level of unreacted Al is dependent on milling time. The maximum amount of AlN was 88.28 wt %. The structure of as‐milled and annealed samples was investigated using x‐ray diffractometry and transmission electron microscopy. Differential thermal analysis ...


New Solutions For The Propagation Of Long Water Waves Over Variable Depth, Yinglong Zhang, Song-Ping Zhu Jan 1994

New Solutions For The Propagation Of Long Water Waves Over Variable Depth, Yinglong Zhang, Song-Ping Zhu

Faculty of Engineering and Information Sciences - Papers: Part A

Based on the linearized long-wave equation, two new analytical solutions are obtained respectively for the propagation of long surface gravity waves around a conical island and over a paraboloidal shoal. Having been intensively studied during the last two decades, these two problems have practical significance and are physically revealing for wave propagation over variable water depth. The newly derived analytical solutions are compared with several previously obtained numerical solutions and the accuracy of those numerical solutions is discussed. The analytical method has the potential to be used to find solutions for wave propagation over more natural bottom topographies.

A Three-Dimensional Numerical Model Of The Response Of The Australian North West Shelf To Tropical Cyclones, Song-Ping Zhu, Jorg Imberger Jan 1994

A Three-Dimensional Numerical Model Of The Response Of The Australian North West Shelf To Tropical Cyclones, Song-Ping Zhu, Jorg Imberger

Faculty of Engineering and Information Sciences - Papers: Part A

A three-dimensional barotropic and baroclinic model is developed to simulate currents and temperature changes induced by tropical cyclones traversing the continental shelf and slope region of the Australian North West Shelf. The model is based on a layered, explicit, finite difference formulation using the nonlinear primitive equations with an embedded entrainment scheme; a mixed-surface-layer interface is defined, which is allowed to shift from one interface to another, depending on the strength of a storm. The model has been tested by simulating the currents and temperature changes induced by tropical cyclones Orson and Ian. The modelled currents and temperatures agreed well ...

Faculty of Engineering and Information Sciences - Papers: Part A

Fresh meat, poultry, and seafood purchased from Seattle area grocery stores were investigated for the presence of Shiga-like toxin-producing Escherichia coli by using DNA probes for Shiga-like toxin (SLT) genes I and II. Of the 294 food samples tested, 17% had colonies with sequence homology to SLT I and/or SLT II genes.


Acceptable Risk: A Conceptual Proposal, Baruch Fischhoff Jan 1994

Acceptable Risk: A Conceptual Proposal, Baruch Fischhoff

RISK: Health, Safety & Environment (1990-2002)

Challenging the "de minimis risk" concept, Dr. Fischhoff argues that risks ought not to be considered apart from a particular technology's benefits. He argues, too, that the acceptability of particular kinds of risks should not be determined without considering the views of all persons who may be exposed. Finally, building upon the "reasonable person" construct, he suggests ways those goals might be achieved.
