1 Lindstrom, Gary E.The schema coercion problemOver the past decade, the ability to incorporate data from a wide variety of sources has become increasingly important to database users. To meet this need, significant effort has been expended in automatic database schema manipulation. However, to date this effort has focused on two aspects of this...Schema coercion; Database schema manipulation; Schema integration1997
2 Lindstrom, Gary E.Migrating relational data to an OODB: strategies and lessions from a molecular biology experienceThe growing maturity of OODB technology is causing many enterprises to consider migrating relational databases to OODBs. While data remapping is relatively straightforward, greater challenges lie in economically and non-invasively adapting legacy application software. We report on a genetics labora...OODB; Relational data; Data migration1997
3 Henderson, Thomas C.Utah range databaseThis document describes in detail the range database provided by the Department of Computer Science at the University of Utah. This document is intended for the person(s) involved in installing the database and those using the database. The images are in four sets: the University of Utah images, SR...Utah range database1986
4 Lindstrom, Gary E.Toward function-based distributed database systemsWe discuss the suitability of a function-based (or "applicative") approach to the construction of distributed database systems. Certain aspects of applicative systems are immediatley appealing for this purpose (e.g. data oriented toward conceptual objects rather than toward particular representation...Function-based; distributed database systems; applicative1982
5 Brandt, Richard C.Building databases for the computer-based memorization systemThe Computer-Based Memorization System (CBMS) consists of eight games used by students to memorize groups of related facts that are stored in an associative network. The instructional design is built into the games. Designing and implementing associative networks for the CBMS is very different from...Computer-Based Memorization System; CBMS1988
6 Lindstrom, Gary E.Consistency and currency in functional databasesWe consider a hybrid model of databases, in which a functional component T is defined as an extension to an imperative component B. T. is loosely coupled to B through a highly parallel function network N. which provides a simple failsafe test of whether an existing assignment of values to a given vi...Functional databases1982
7 Freire, JulianaManaging XML data: an abridged overviewXML's flexibility makes it a natural format for both exchanging and integrating data from diverse data sources. In this survey, the authors give an overview of issues in managing XML data, discuss existing solutions, and outline the current technology's open problems and limitations.XDM2004-07
8 Freire, JulianaDesigning information-preserving mapping schemes for XMLAn XML-to-relational mapping scheme consists of a procedure for shredding XML documents into relational databases, a procedure for publishing databases back as documents, and a set of constraints the databases must satisfy. In previous work, we discussed two notions of information preservation for m...Losslessness; Validation; Mapping scheme; Edge++; LILO; Lossless Inlining; Lossless Outlining; XML Schema2005
9 Riesenfeld, Richard F.Computer aided designThe report is based on the proposal submitted to the National Science Foundation in September 1981, as part of the Coordinated Experimental Computer Science Research Program. The sections covering the budget and biographical data on the senior research personnel have not been included. Also, the sec...1984
10 Henderson, Thomas C.Apparent symmetries in range dataA procedure for extracting symmetrical features from the output of a range scanner is described which is insensitive to sensor noise and robust with respect to object surface complexity. The acquisition of symmetry descriptors for rigid bodies from a range image was in this case motivated by the ne...Symmetry descriptors; Range data; Range scanner; Dextrous manipulation systems1987
11 Henderson, Thomas C.UPE: Utah prototyping environment for robot manipulatorsDeveloping an environment that enables optimal and flexible design of robot manipulators using reconfigurable links, joints, actuators, and sensors is an essential step for efficient robot design and prototyping. Such an environment should have the right "mix" of software and hardware components fo...prototyping environment; robot manipulators1994
12 Freire, JulianaOrganizing hidden-web databases by clustering visible web documentsIn this paper we address the problem of organizing hidden-Web databases. Given a heterogeneous set of Web forms that serve as entry points to hidden-Web databases, our goal is to cluster the forms according to the database domains to which they belong. We propose a new clustering approach that mode...Hidden-web databases; Web documents2007-04
13 Sobh, Tarek M.; Henderson, Thomas C.Prototyping environment for robot manipulatorsDeveloping an environment that enables optimal and flexible design of robot manipulators using reconfigurable links, joints, actuators, and sensors is an essential step for efficient robot design and prototyping. Such an environment should have the right "mix" of software and hardware components for...Prototyping; Robot manipulators1994
14 Freire, JulianaShreX: managing XML documents in relational databasesWe describe ShreX, a freely-available system for shredding, loading and querying XML documents in relational databases. ShreX supports all mapping strategies proposed in the literature as well as strategies available in commercial RDBMSs. It provides generic (mapping-independent) functions for...ShreX; XML Schema; Mapping strategies2004
15 Freire, JulianaBridging the XML-relational divide with LegoDB: a demonstrationWe present LegoDB, a cost-based XML storage mapping engine that automatically explores a space of possible XML-to-relational mappings and selects an efficient mapping for a given application.LegoDB; Storage mappings2003
16 Henderson, Thomas C.RobotShare: a framework for robot knowledge sharingKnowledge representation is a traditional field in artificial intelligence. Researchers have developed various ways to represent and share information among intelligent agents. Agents that share resources, data, information, and knowledge perform better than agents working alone. However, previou...RobotShare; Robot knowledge sharing2007
17 Susarla, Sai R.; Carter, JohnFlexible consistency for wide area peer replicationThe lack of a flexible consistency management solution hinders P2P implementation of applications involving updates, such as read-write file sharing, directory services, online auctions and wide area collaboration. Managing mutable shared data in a P2P setting requires a consistency solution that...Wide area; Peer replication2004-11-18
18 Bruderlin, BeatAn axiomatic approach for solving geometric problems symbolicallyThis paper describes a new approach for solving geometric constraint problems and problems in geometry theorem proving. We developed a rewrite-rule mechanism operating on geometric predicates. Termination and completeness of the problem solving algorithm can be obtained through well foundedness and ...Geometric constraint problems; Geometry theorem proving; Knuth-Bendix completion algorithm1990
19 Henderson, Thomas C.An approach to three-dimensional scene databasesCurrent image database research is concerned for the most part with the encoding and processing of two-dimensional images. However, the most successful approach to computer vision is based on 3-dimensional information, organized as either stacks of 2-D images (e.g., the intrinsic images of Barrow an...Image databases; Three-dimensional; Scene databases1987
20 Freire, Juliana; Silva, Claudio T.VisComplete: automating suggestions for visualization pipelinesBuilding visualization and analysis pipelines is a large hurdle in the adoption of visualization and workflow systems by domain scientists.

24 Freire, JulianaTaking I/O seriously: resolution reconsidered for diskModern compilation techniques can give Prolog programs, in the best cases, a speed comparable to C. However, Prolog has proven to be unacceptable for data-oriented queries for two major reasons: its poor termination and complexity properties for Datalog, and its tuple-at-a-time strategy. A number of...Tabling; SLG-WAM; Prolog; XSB; Datalog1997
25 Freire, JulianaSiphoning hidden-web data through keyword-based interfacesIn this paper, we study the problem of automating the retrieval of data hidden behind simple search interfaces that accept keyword-based queries.
