Harp: A Distributed Query System For Legacy Public Libraries And Structured Databases, Ee Peng Lim, Ying Lu

Research Collection School Of Computing and Information Systems

The main purpose of a digital library is to facilitate users easy access to enormous amount of globally networked information. Typically, this information includes preexisting public library catalog data, digitized document collections, and other databases. In this article, we describe the distributed query system of a digital library prototype system known as HARP. In the HARP project, we have designed and implemented a distributed query processor and its query front-end to support integrated queries to preexisting public library catalogs and structured databases. This article describes our experiences in the design of an extended Sequel (SQL) query language known as HarpSQL. …

Making Sharing Pervasive: Ubiquitous Computing For Shared Note Taking, James A. Landay, Richard C. Davis

Research Collection School Of Computing and Information Systems

As a variety of low-cost note-taking devices becomes pervasive, shared notes can help work groups better communicate ideas and information. To explore this idea further, we carried out three related case studies of how members of a large research group shared meeting notes. The group found value in combining personal notes and presentation slides with a single, unifying document, such as regular meeting minutes. The minutes provided structure when there were too many sources of notes. We used this insight in our design of NotePals, a note-sharing system with a lightweight process, an interface, and hardware that distinguish it from …

Measurement Of W-Pair Production In E+E- Collisions At 183 Gev, R. Barate, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

The production of W+W− pairs is analysed in a data sample collected by ALEPH at a mean centre-of-mass energy of 182.7 GeV, corresponding to an integrated luminosity of 57 pb−1 . Cross sections are given for different topologies of W decays into leptons or hadrons. Under Standard Model assumptions for the W-pair production and decay, the W-pair cross section is measured to be 15.57 ± 0.62(stat.) ± 0.29(syst.) pb. Using also the W-pair data samples collected by ALEPH at lower centre-of-mass energies, the decay branching ratio of the W boson into hadrons is measured to be B(W → hadrons) = …

Search For Invisible Higgs Boson Decays In E+E- Collisions At Centre-Of-Mass Energies Up To 184 Gev, R. Barate, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

In a data sample of 78.3 pb−1 collected in 1996 and 1997 by the ALEPH detector at centre-of-mass energies from 161 to 184 GeV, invisible decays of a Higgs boson have been searched for in the reaction e+e− → hZ, where the Z can decay into e+e−, µ+µ− or q¯q. No evidence for a signal is found and limits on the production cross section are derived as a function of the Higgs boson mass. These results are combined with those obtained in an update of the analyses of the ALEPH data taken at LEP 1. For a production cross section …

Measurement Of The Hadronic Photon Structure Function At Lep 1 For 〈Q2〉 Values Between 9.9 And 284 Gev2, Barate, R.; Et Al., M. Thulasidas

Research Collection School Of Computing and Information Systems

Inclusive γ∗γ interactions to hadronic final states where one scattered electron or positron is detected in the electromagnetic calorimeters have been studied in the LEP 1 data taken by ALEPH from 1991 to 1995. The event sample has been used to measure the hadronic structure function of the photon F2γ in three bins with 〈Q2〉 of 9.9, 20.7 and 284 GeV2.

Measurement Of The W Mass In E+E- Collisions At 183 Gev, Barate, R.; Et Al., M. Thulasidas

Research Collection School Of Computing and Information Systems

The mass of the W boson is obtained from reconstructed invariant mass distributions in W-pair events. The sample of W pairs is selected from 57 pb−1 collected with the ALEPH detector in 1997 at a centre-of-mass energy of 183 GeV.

Search For The Standard Model Higgs Boson At The Lep2 Collider Near √S = 183 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

During 1997 the ALEPH experiment at LEP gathered 57pb−1 of data at centre-of-mass energies near 183 GeV. These data are used to look for possible signals from the production of the Standard Model Higgs boson in the reaction e+e−→HZ. No evidence of a signal is found in the data; seven events are selected, in agreement with the expectation of 7.2 events from background processes. This observation results in an improved lower limit on the mass of the Higgs boson: mH>87.9GeV/c2 at 95% confidence level.

Determination Of |Vub| From The Measurement Of The Inclusive Charmless Semileptonic Branching Ratio Of B Hadrons, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

From a study of the kinematic properties of the final state produced in the semileptonic decays b→Xℓνℓb→Xℓνℓ, the inclusive charmless semileptonic branching ratio of b hadrons is measured. With a sample of 3.6 million hadronic Z decays recorded between 1992 and 1995 with the ALEPH detector at LEP, the value Br(b→Xuℓνℓ)Br(b→Xuℓνℓ) is determined to be (1.73±0.55stat±0.55syst)×10−3(1.73±0.55stat±0.55syst)×10−3, where XuXu represents any charmless hadronic state and b is a mixture of b hadrons weighted by their production rates. This measurement yields the result|Vub|2=(18.68±5.94stat±5.94syst±1.45HQE)×10−6,|Vub|2=(18.68±5.94stat±5.94syst±1.45HQE)×10−6,where the last error comes from the conversion of the branching ratio to the CKM matrix element squared.

Search For Supersymmetry With A Dominant R-Parity Violating Lqd̄ Coupling In E+E- Collisions At Centre-Of-Mass Energies Of 130 Gev To 172 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

A search for pair-production of supersymmetric particles under the assumption that R-parity is violated via a dominant LQD¯LQD¯ coupling has been performed using the data collected by ALEPH at centre-of-mass energies of 130–172 GeV. The observed candidate events in the data are in agreement with the Standard Model expectation. This result is translated into lower limits on the masses of charginos, neutralinos, sleptons, sneutrinos and squarks. For instance, for m0=500m0=500 GeV/c2/c2 and tanβ=2–√tan⁡β=2 charginos with masses smaller than 81 GeV/c2/c2 and neutralinos with masses smaller than 29 GeV/c2/c2 are excluded at the 95% confidence level for any generation structure of …

Decision Analytic Approach To Severe Head Injury Management., Harmanec D., Tze-Yun Leong, Sundaresh S., Poh K., Yeo T., Ng I., Lew T.

Research Collection School Of Computing and Information Systems

Severe head injury management in the intensive care unit is extremely challenging due to the complex domain, the uncertain intervention efficacies, and the time-critical setting. We adopt a decision analytic approach to automate the management process. We document our experience in building a simplified influence diagram that involves about 3000 numerical parameters. We identify the inherent problems in structuring a model with unclear domain relationships, numerous interacting variables, and real-time multiple inputs. We analyze the effectiveness and limitations of the decision analytic approach and present a set of desiderata for effective knowledge acquisition in this setting. We also propose a …

A Submersible Battery-Powered Flow Injection (Fi) Sensor For The Determination Of Nitrate In Estuarine And Coastal Waters., Anthony R.J. David, Trevor Mccormack, Paul J. Worsfold

School of Geography, Earth and Environmental Sciences

The design, construction and performance of a remotely deployed submersible flow injection-based nutrient (total oxidized nitrogen) sensor are described. The sensor featured a custom-built microcomputer and a solid-state, flow-through spectrophotometric detector, and the derivatization chemistry was based on in-line copper-cadmium reduction of nitrate to nitrite, and diazotization with N1NED and sulphanilamide. The limit of detection was 0.0014 mg l(-1) NO3-N and the linear range was 0.0014- 0.77 mg l(-1) with a 260 microl sample volume and a 20 mm path length flow cell. Results from submersed deployments in the Tamar estuary and North Sea are also reported.

The purpose of this phenomenological study is to explore and describe the lived experience of women's health centre coordinators. In addition to the intrinsic value of telling these women's stories, this research provides data which can he used to strengthen the economic, political, organisational and social position of women’s health centres and the women who work in them. Four women managers from regional urban women's health centres in Australia were interviewed about their subjective experiences with respect to their current working roles. Interviews were audio taped, transcribed and coded to produce themes and to preserve anonymity. Data was analysed using …

Malpractice And The Tax Practitioner: An Analysis Of The Areas In Which Malpractice Occurs, Jacob L. Todres

Faculty Publications

(Excerpt)

As an attorney for approximately twenty-five years, I have been cognizant of the apparent increase in litigiousness of modem society, and of the concomitant increase in malpractice suits against professionals, both lawyers as well as non-lawyers. As a teacher of tax law, I am especially interested in how this trend impacts the tax lawyer, as well as other tax practitioners. What I am especially interested in is determining which areas of tax law and tax practice have generated the most malpractice claims so that practitioners may embark into such areas forewarned. Unfortunately, most of the existing literature focuses on …

Efficient Dynamic Unstructured Methods And Applications For Transonic Flows And Hypersonic Stage Separation, Xiaobing Luo

Mechanical & Aerospace Engineering Theses & Dissertations

Relative-moving boundary problems have a wide variety of applications. They appear in staging during a launch process, store separation from a military aircraft, rotor-stator interaction in turbomachinery, and dynamic aeroelasticity.

The dynamic unstructured technology (DUT) is potentially a strong approach to simulate unsteady flows around relative-moving bodies, by solving time-dependent governing equations. The dual-time stepping scheme is implemented to improve its efficiency while not compromising the accuracy of solutions. The validation of the implicit scheme is performed on a pitching NACA0012 airfoil and a rectangular wing with low reduced frequencies in transonic flows. All the matured accelerating techniques, including the …

The Impacts And Implementation Of Integrated Marketing Communications, Min-Fang Wu

Theses

In the current market place, there are two points that occupy the marketer's attention. One is the necessity of integration; the other is the importance of communications. Integrated Marketing Communications (IMC) is the crystallization of the two thoughts.

Because the entire market place is changing so rapidly, factors that result in a successful business are too complicated. Integration of all kinds of market resources is no longer a marketing theory which is discussed by academics. It has become a necessary solution to business.

On the other hand, the popular issue of communication does not simply reflect the deep relationship of …

Vitamin Effect On The Aerobic Biodegradation Of Phenanthrene, Antracene, Fluoranthene, And Pyrene In A Contaminated Soil From An Industrial Site, Ilkay Cam

Theses

Bioremediation of organic wastes is often a cost-effective technology for the in situ treatment of contaminated soils. In this study, the possibility of increasing the rate and extent of biodegradation for phenathrene, anthracene, fluoranthene, and pyrene in an industrial PAH contaminated soil via vitamin mixture supplementation was explored.

Soil contained with PAHs was obtainecl from the Bayway refinery site formerly owned by Exxon (Linden, NJ). Experiments were conducted in which the contaminated soil was amended with a mixtures of four vitamins (niacin, biotin, folic acid, and panthothenic acid). Peat moss, a common soil amendment, was also added in some experiments. …

A Comparative Analysis Of Women's Issues: Toward A Contextualized Approach, Antoinette M. Sedillo Lopez

Faculty Scholarship

"This Article proposes a methodology for comparative analysis of women's rights using insights from critical race theory and feminism. Comparative analysis by a Western scholar must reconcile a perspective developed in the United States with respect for another culture. In discussing women's rights, lawyers, judges, students and sociologists have justified certain women's situations as an inherent aspect of culture. For example, traditional "female genital surgery" has been defended as a "mere bodily mutilation" that is the "sine qua non of the whole teaching of tribal law, religion, and morality." In Mexico, "machismo" has been justified as an immutable characteristic of …

Introduction: Latcrit Theory: Mapping It's Intellectual And Political Foundations And Future Self-Critical Directions, Margaret E. Montoya

Faculty Scholarship

The third annual gathering of LatCrit scholars has resulted in this cluster of essays and articles that continue the work of defining the foundations and the future directions of this legal scholarship movement. As described in some of the articles within this cluster, LatCrit has had the benefit of learning valuable lessons from other slightly older schools of critical legal theory, most particularly from the Critical Race Theory ("CRT") Workshop. The LatCrit movement has been strengthened because scholars identified primarily with CRT working with and alongside scholars identified primarily with LatCrit have struggled to recognize, name and address the hetero-normativity …

Emphasizing Torts In Claims Of Discrimination Against Black Female Athletes, Alfred Dennis Mathewson

Faculty Scholarship

In Black Women, Gender Equity and the Function at the Junction, I argued that an equality-based legal regime does not provide an adequate remedy for African-American female athletes. Instead I suggested that a tort-based regime may be more appropriate. I did so knowing that gender and racial discrimination are torts and I did not intend to suggest otherwise. They are statutory torts founded upon equality principles. What I intended was to draw more upon the general tort principles involved in an antidiscrimination action. I specifically invoked the notion of using mass tort theories. I wish to sketch a brief but …

Entrenching Interests: State Supermajority Requirements To Raise Taxes, Max J. Minzner

Faculty Scholarship

At the opening of the 104th Congress, the new Republican majority imposed the first supermajority requirement "limited to particular cases" in the history of Congress. The unanswered question is whether the Rule is a good idea, particularly whether this Rule is well designed. The states have extensive experience with supermajority requirements for tax increases. This article attempts to answer the question of supermajority design. If alterations in the tax code are to be restricted, how should they be limited? To what type of bills should a supermajority requirement apply? At what level should the requirement be implemented? When and how …
