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.

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 …
