Search For A Fourth-Generation Quark More Massive Than The Z0 Boson In Pp̅ Collisions At √S = 1.8 Tev, T. Affolder, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

We present the results of a search for pair production of a fourth-generation charge -⅓ quark (b′) in √s =1.8 TeV pp collisions using 88 pb^-1 of data obtained with the Collider Detector at Fermilab. We assume that both quarks decay via the flavor-changing neutral current process b′ → bZ⁰ and that the b′ mass is greater than m_z+ m_b. We studied the decay mode b′b̅′→ Z⁰Z⁰ bb̅ where one Z⁰ decays into e⁺e^- or μ⁺μ^-and the other decays hadronically, …

Transverse Momentum And Total Cross Section Of E+E- Pairs In The Z-Boson Region, T. Affolder, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

The transverse momentum and total cross section of e⁺e^- pairs in the Z-boson region of 66 < M_ee < 116 GeV/c² from pp̅ collisions at √s =1.8 TeV are measured using 110 pb^-1 of collisions taken by the Collider Detector at Fermilab during 1992–1995. The total cross section is measured to be 248 ± 11 pb. The differential transverse momentum cross section is compared with calculations that match quantum chromodynamics perturbation theory at high transverse momentum with the gluon resummation formalism at low transverse momentum.

Integration Of Multi Lifecycle Assessment And Design For Environment Database Using Relational Moddel Concepts, Bhagyashree Suratran

Theses

Multi-lifecycle Assessment (MLCA) systematically considers and quantifies the consumption of resources and the environmental impact associated with a product or process. Design challenges posed by a multi-lifecycle strategy are significantly more complex than traditional product design. The designer must look forward in time to maximize the product's end-of-life yield of assemblies, parts and materials while looking backward to the world of existing products for feedstock sources for the current design. As MLCA and DEE share some common data items, such as, part geometry, material and manufacturing process, it is advantageous to integrate the database for MLCA and DEE. The integration …

A Comparison Of Field-Delineated Wetlands To The New Jersey Freshwater Wetland Maps, David P. Moskowitz

Theses

A comparison of the New Jersey Freshwater Wetland maps to field-delineated wetlands was undertaken to assess the accuracy of the Freshwater Wetland maps. The evaluation revealed substantial differences in the amount of wetland acreage on the Freshwater Wetland maps compared to field-verified wetlands. Forty study sites comprising 21,877 acres (8,854h) were evaluated. Of these, twenty-seven were overmapped (more wetland acreage than was field-verified), and thirteen were undermapped. Forty-three percent had mapping discrepancies at or above fifty percent; when modified land designations were included as wetlands, the number of sites at this threshold increased to fifty percent.

To Who Or What Do We Owe Sustainable Development? A Search For An Ethical Framework For Sustainable Development, Mia Soderlund

Theses

This thesis focuses on the ethical dimension of sustainable development as described in the Bruntland report. According to this report, we do have certain moral obligations to future generations. This thesis asks whether traditional moral philosophy, such as utilitarian and contractarian theories, can justify moral obligations to future generations, and if they can serve as ethical frameworks for sustainable development.

The basic idea with sustainable development is to create a balance between society, the environment and the economy. If the environment is ascribed instrumental value, which is the case with traditional moral philosophy then there is no balance, because its …

Intelligent Process For Uasb Reactors, Sita Mohan

Theses

The Upflow Anaerobic Sludge Blanket (UASB) reactor is widely used for the anaerobic treatment of concentrated municipal / industrial wastewaters and sludges. Ability to handle high organic loading rates and cost effectiveness are often the most cited merits of the UASB process. Numerous mathematical models have been developed to describe the process and mechanistic phenomena in these systems. However, evidence in the literature of these models having been applied, either as control or diagnostic tools is limited. The use of intelligent process control mechanisms can greatly ease problems associated with operating these reactor systems.

The objective of this study is …

Late Deflation Study : Hemodynamic Effects Of Iab Timing In Humans, Manal Morcos

Theses

Conventional IABP timing deflates 100% of the balloon volume before the onset of left ventricular ejection and has been well established in the literature as a safe and effective method. Yet, recent studies suggest that deflation of the IAB at or near the onset of systole improve myocardial efficiency (Kern, 1999, 1129). To test whether deflation of the JAB at a later deflation time reduces left ventricular workload and enhances coronary perfusion, four timing methods were evaluated in 20 patients: T₁ (100% JAB volume deflated before onset of ejection), T₂ (60% IAB volume deflated before and 40% volume …

Automatic Categorization Of Abstracts Through Bayesian Networks, William Ramirez

Theses

This thesis presents a method for assigning abstracts of Artificial Intelligence papers to their area of the field. The technique is implemented by the use of a Bayesian network where relevant keywords extracted from the abstract being categorized, are entered as evidence and inferencing is made to determine potential subject areas. The structure of the Bayesian network represents the causal relationship between Artificial Intelligence keywords and subject areas. Keyword components of the network are selected from precategorized abstracts. The work reported here is part of a larger project to automatically assign papers to reviewers for Artificial Intelligence conferences. The process …

A Study Of Platinum, Palladium, Bismuth, Copper, And Silver For The Potentiometric Determination Of Chlorine, Maria A. Gottwald

Theses

This research was undertaken to determine which metals would be suitable to be used as electrodes for the determination of the concentration of chlorine in aqueous solutions at various pH levels. Platinum, palladium, bismuth, copper and silver electrodes were constructed and tested to determine their applicability for measuring the concentration of chlorine in drinking water, waste water treatment plant effluent, and swimming pools. Buffer solutions were used which varied in pH from 7 to 8, and in cHorine concentration from 0 to 10 ppm. In addition, the potential variation over time was observed for each electrode in the solutions.

Platinum, …

Editing Mpeg2 Video In Compressed Domain, Ren Egawa

Theses

As MPEG2 becomes the heart of most digital video applications, the need to edit an MPEG2 bitstream video in compressed domain has increased. To realize this need, two major technical issues must be resolved: decoder buffer and segment extraction.

In the decoder buffer issue, the edited stream must ensure that the buffer would not overflow or underfiow as the result of the editing. This thesis invented a mathematical model that could describe the editing task and predict the editing effect on the buffer. Based on this model, the thesis then built a method to edit a stream safely. This method …

A Study Of Factors Affecting Cardiovascular Reactivity, Andrew Gill Ventura

Theses

This pilot study was conducted to determine what affects the cardiovascular reactivity of different people. Variables such as the order of stress-inducing and relaxing activities, performing multiple tasks on different days, personality, familial history of diseases, and general health were investigated as to their effects, if any, on cardiovascular reactivity.

Ten healthy, normal male subjects, aged 18 - 33 years, volunteered to be subjected to studies on three experimental days, the first one being for gathering information. On the second and third days, the subjects performed the following activities: mental arithmetic, numeric repetition, 10 breaths-per-minute (bpm) paced-breathing, and normal breathing, …

A Visualization System For Information Retrieval And Mining In High Dimensional Databases, Xinhuan Zheng

Theses

In this thesis, we present a search engine capable of giving good heuristic answers to the queries on a structural database. A structural database holds structural objects, e.g., protein secondary and tertiary structures, 3D molecules, phylogenetic trees, neuroanatomical networks, parse trees, CAD/CAM parts, and XML documents. Answering queries on such databases often requires solving variants of the graph isomorphism or subisomorphism problems. We also describe a graphic user interface which interacts with users to facilitate visualizing query results. We use 3D molecules (graphs) as illustrating examples, though our prototype is able to handle many other different types of structural data.

Analysis Of Clustering Algorithms For Spike Sorting Of Multiunit Extracellular Recordings, Jayesh Rege

Theses

Various techniques have been considered in the past to identify distinct spike shapes from mulitunit extracellular recording. These techniques involve adaptive filtering techniques or template matching techniques or hierarchical clustering techniques. In this investigation, we have used Principal Component Analysis followed by various clustering techniques to identify distinct spike shapes. The amplitude filter is used to separate spikes from background neuronal activity. The correlation matrix of the spike data is used to compute principal component wave forms. Each spike is thus represented by the coefficients of principal components. Then, We have used agglomorative hierarchical clustering algorithm to perform the initial …

Perturbed Laplacian Matrix And The Structure Of A Graph., Sukanta Pati Dr.

Doctoral Theses

Laplacian matrices Let G be a connected simple graph with vertex set V = {1,2,.,n), edge set E and let each edge be associated with a positive number, the weight of the edge. The above graph is called a weighted graph. An unweighted graph is just a weighted graph with each of the edges bearing weight 1. All the graphs considered are weighted and simple, unless specified otherwise; all the matrices considered are real. The adjacency matrix A(G) related to this graph is defined as A(G) = (aij), whereaij, if (i, j] € E and the weight of the edge …

Correcting Eddy-Covariance Flux Underestimates Over A Grassland, T. E. Twine, W. P. Kustas, J. M. Norman, D. R. Cook, P. R. Houser, T. P. Meyers, J. H. Prueger, P. J. Starks, M. L. Wesley

United States National Aeronautics and Space Administration: Publications

Independent measurements of the major energy balance flux components are not often consistent with the principle of conservation of energy. This is referred to as a lack of closure of the surface energy balance. Most results in the literature have shown the sum of sensible and latent heat fluxes measured by eddy covariance to be less than the difference between net radiation and soil heat fluxes. This under-measurement of sensible and latent heat fluxes by eddy-covariance instruments has occurred in numerous field experiments and among many different manufacturers of instruments. Four eddy-covariance systems consisting of the same models of instruments …

Collegiate Grading Practices And The Gender Pay Gap, Alicia C. Dowd

Education Policy Analysis Archives (EPAA)

Extending research findings by R. Sabot and J. Wakeman-Linn (1991), this article presents a theoretical analysis showing that relatively low grading quantitative fields and high grading verbal fields create a disincentive for college women to invest in quantitative study. Pressures on grading practices are modeled using higher education production functions.
