On Document Filing Based Upon Predicates, Zhijian Zhu

Dissertations

This dissertation presents a formal approach to modeling documents in a personal office environment, proposes a heterogeneous algebraic query language to manipulating objects (folders) in the document model, and investigates a predicate-driven document filing system for automatically filing documents.

The document model was initially proposed in [38] which adopts a very natural view for describing the office documents using the relational and object-oriented paradigms. The model employs a dual approach to classifying and categorizing office documents by defining both a document type hierarchy and a folder organization. This dissertation extends and specifies formally the document model. Documents are partitioned into …

A Graphical Environment For Change Detection In Structured Documents, Girish A. Patel

Theses

Change detection in structured documents (e.g. SGML is important in data warehousing, digital libraries and Internet databases. This thesis presents a graphical environment for detecting changes in the structured documents. We represent. each document by alp ordered labeled tree based on the underlying markup language. We then compare two documents by invoking previously developed algorithms for approximate pattern matching and pattern discovery in trees. Several operators are developed to support. the comparison of the documents; graphical devices are provided to facilitate the use of the operators. We believe the proposed tool is useful for not only document management, but also …

Object Oriented Partitioning For A Medical Vocabulary Based On Semantic Network, Mansnimar Singh

Theses

Computers have become ubiquitous and indispensable part of everyday life both for personal use and in the workplace. Medicine is one of the few domains that has not fully adopted computerization. One impediment to this emanates from a communication gap between the computer science professional and the medical professional. Besides, medical terminology is full of synonyms and medical professionals use them according to their personal preferences. This lack of common terminology has prevented sharing of knowledge and automating data processing, resulting in the healthcare information explosion.

Semantic network models have been developed to represent medical concepts and to provide a …

Design And Implementation Of On-Line Metrics, Ashok Vantipalli

Theses

The performance of a software product plays an important role in the software industry to survive the tough competition given by the other software vendors. The real test for a software product starts after its release when it is extensively used by the end users and in different environments. And the software goes through a number of tests by the end users which can be very different and insufficient from the regression tests the software vendor performed on it. This critical issue; requires each vendor to have a department mainly dealing with the testing and analysing the performance of a …

Mathematics And Values: Can Philosophy Guide Projects?, Michael H. Veatch

ACMS Conference Proceedings 1997

The philosophy of mathematics has provided insight on questions of foundations and mathematical truth; however, it has not been very fruitful in guiding the practice of mathematics. This paper attempts to find points of contact between a Christian worldview and the choice of mathematical projects and methods. Three areas are considered: (i) dubitability in current research, (ii) the intrinsic value of contemporary mathematics to contemporary society, and (iii) the affirmation of human value in the use of mathematics. Finally, a framework for valuing mathematics is proposed as an encouragement to think more deeply about how a Christian might choose a …

The Circulating Processor Model Of Parallel Systems, Amy Apon, Lawrence Dowdy

Publications

This paper introduces the circulating processor model for parallel computer systems. The circulating processor model is a product form queuing network model where the processors are allowed to circulate between the parallel applications instead of the more traditional circulating task model. Certain behaviors of parallel systems are better captured using this new approach. The circulating processor model may be load dependent or load dependent. The load dependent circulating processor model is exact for systems which contain a single parallel application. An exact error is calculated for the load independent circulating processor model for systems which contain a single parallel application. …

Source-Aware Multidatabase Query Processing, Ee Peng Lim, Yinyan Cao, Roger Hsiang-Li Chiang

Research Collection School Of Computing and Information Systems

We introduce a multidatabase model to represent the information that derives from different local databases. This model, known as Tuple-Source (TS) relational model, accommodates tuples from different local databases by attaching them with their source information in the global relations which are also known as TS-relations. In other words, a source attribute is implicit in every TS-relation. To manipulate the global relations, we have developed the TSSQL query language and implemented a distributed query processor to process such queries. In this paper, we report our distributed query processing architecture and algorithms. Our architecture consists of a query mediator and a …

Terminal Emulation System, Chun-Fu Lee

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Terminal emulation is a personal computer application software which emulates the terminal's behavior to communicate with the mainframe/host computer. It can show the terminal screen on a personal computer screen and make the mainframe/host computer interact with it as it would with a real terminal without any distinction.

Personal computers are increasingly more powerful and efficient today. Their mobility, compatibility, flexibility, and extendibility are definitely superior to the 'dumb' traditional terminals. Terminal emulation is therefore devised to take advantage of these personal computers' redemptions to offset the traditional terminal's drawbacks and inconveniences.

A terminal emulation is actually a very complex …

Characterizing A Portable Subset 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 VHDL-93 features such as shared variables and postponed processes that change the underlying semantic model. In the presence of shared variables, nondeterministic 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. Our specification can serve as a correctness criteria for a VHDL-93 simulator.

On The Automatic Generation Of Network Protocol Simulators, Andrew Chen

Honors Theses

Computers communicate with each other over various communication networks via a language known as a protocol. The design of the protocol can have a significant impact on the efficiency (and effectiveness) of the network. Because building an actual network to test the performance (and reliability) of a new protocol is rather expensive and time consuming, there is an interest in simulating network protocols in order to determine how efficient the communication network is. We are therefore interested in automatically generating simulators that could measure the performance of the new protocols. There are two main parts to this project. The first …

Distributed Query Processing For Structured And Bibliographic Databases, Ee Peng Lim, Ying Lu

Research Collection School Of Computing and Information Systems

To support future digital library systems which draw information from different sources on the internet, we have to provide integrated queries to pre-existing database servers which contain structured, semi-structured and unstructured data. In this paper, we specifically examine the problem of querying both existing structured relational databases and bibliographic databases. By adopting the well-accepted Z39.50 standard protocol to access bibliographic databases in different legacy library systems, we have developed an extended SQL model, known as HarpSQL, to support integrated queries to both SQL databases and bibliographic databases. Using HarpSQL, one can not only query bibliographic databases in an SQL manner, …
