Quality Evaluation Methods – A Review, Boyan N. Dimitrov

Mathematics Publications

Quality is understood as a set of features that determine how a product fits to satisfy certain needs. Therefore, a set of measurements X1, X2,…, Xn characterizes each product, and also serves as information in evaluation of product's quality. Individual measurements Xi are quantitative (numerical) or qualitative (non-numerical) variables expressing the value of the ith index of quality. Evaluation of the overall level of quality, comparison of similar products, measuring and reporting quality improvement and other related problems need construction of some integral quality index Q in which all individual measurements are taken into account. Several proposals for integral quality …

Holistic Approaches In A Secondary Discipline-Based Art Education Curriculum, Jennifer Hicks Limle

Theses, Dissertations and Capstones

The primary objective of this study is to examine the possible advantages of incorporating the principles and strategies of whole language to a secondary art education curriculum. Reading, or the process of decoding symbols, is an integral part of the learning process. It is particularly pertinent to the three academically oriented components of Discipline-Based Art Education: art criticism, art history, and the study of aesthetics. The holistic strategies promoted by the whole language movement, may be characterized by an emphasis on written responses and experience-oriented, student-centered curriculum. This approach is expected to enhance the DBAE curriculum.

Influences Of Acid Mine Drainage On Water Chemistry Of Blackwater River Watershed, Carla C. Morato-Lara

Theses, Dissertations and Capstones

Acidic mine drainage flow from active and abandoned coal mines has been a major source of water pollution in the Appalachian Mountain region of the eastern USA. Water samples were collected and analyzed from Blackwater River watershed during 2 years (September 1996 - May 1998). The water quality measurements determined that the Beaver Creek and North Fork tributaries were affected by acid mine drainage but not Yellow Creek. Beaver Creek and North Fork stations had high sulfate and manganese markers of acid mine drainage, whereas Yellow Creek was slightly acidic with low sulfate and manganese. North Fork was the primary …

Approaches To A Generalized Synthesis For Hexaphenylbutadiene, Karena Kaye Linkenhoger Robinson

Theses, Dissertations and Capstones

This study was concerned with the attempted development of a generalized synthesis of hexaphenylbutadiene. Three methods were attempted: Michael Addition of cyanide to -phenylcinnamate followed by organolithium or Grignard addition; reaction of benzil with two moles of the Wittig reagent prepared from bromodiphenylmethane; reaction of two moles of benzophenone with the bisphosphorane prepared from 1,2- dibromo-1,2-diphenylethane.

The Mechanics And Regulation Of Rat Aortic Smooth Muscle Contraction: Implications Of Cytoskeletal Remodeling, Protein Phosphorylations, And Microtubule-Based Kinase Transport, Alison Summers Battistella-Patterson

Theses, Dissertations and Capstones

The exact nature of the mechanisms and the regulation of vascular smooth muscle contraction is not well understood. To better understand these processes, we examined two systems involved in smooth muscle contraction, the cytoskeleton and the protein kinases. In order to study the role of the cytoskeleton in smooth muscle contraction, we examined the contractile and mechanical effects of cytoskeleton disruption. We found that the relationship between passive tension applied to aortic rings and the resulting increase in tissue length was nearly linear over the range of 1 g to 15 g. However, even with increasing tissue length, within the …

Twisting Of X-Ray Isophotes In Triaxial Galaxies, Aaron J. Romanowsky, C. S. Kochanek

Faculty Publications

We investigate X-ray isophote twists created by triaxiality differences between the luminous stellar distributions and the dark halos in elliptical galaxies. For a typically oblate luminous galaxy embedded in a more prolate halo formed by dissipationless collapse, the triaxiality difference of ΔT simeq 0.7 leads to typical isophote twists of langΔψXrang simeq 16° ± 19° at 3 effective stellar radii. In a model that includes baryonic dissipation, the effect is smaller, with ΔT simeq 0.3 and langΔψXrang simeq 5° ± 8°. Thus, accurate measurements of X-ray isophote twists may be able to set constraints on the interactions between baryons and …

Definitional Interpreters For Higher-Order Programming Languages, John C. Reynolds

College of Engineering and Computer Science - Former Departments, Centers, Institutes and Projects

Abstract. Higher-order programming languages (i.e., languages in which procedures or labels can occur as values) are usually defined by interpreters that are themselves written in a programming language based on the lambda calculus (i.e., an applicative language such as pure LISP). Examples include McCarthy’s definition of LISP, Landin’s SECD machine, the Vienna definition of PL/I, Reynolds ’ definitions of GEDANKEN, and recent unpublished work by L. Morris and C. Wadsworth. Such definitions can be classified according to whether the interpreter contains higher-order functions, and whether the order of application (i.e., call by value versus call by name) in the defined …

Dynamic Management Of Heterogeneous Resources, Jerrell Watts, Marc Rieffel, Stephen Taylor

College of Engineering and Computer Science - Former Departments, Centers, Institutes and Projects

This paper presents techniques for dynamic load balancing in heterogeneous computing environments. That is, the techniques are designed for sets of machines with varying processing capabilities and memory capacities. These methods can also be applied to homogenous systems in which the effective compute speed or memory availability is reduced by the presence of other programs running outside the target computation. To handle heterogeneous systems, a precise distinction is made between an abstract quantity of work, which might be measured as the number of iterations of a loop or the count of some data structure, and the utilization of resources, measured …

Visual Interactive Modeling In A Java-Based Hierarchical Modeling And Simulation System, Robert G. Sargent, Thorsten Daum

College of Engineering and Computer Science - Former Departments, Centers, Institutes and Projects

The desired set of properties of a modern simulation system is presented. The portion of the Hierarchical Modeling And Simulation System-Java (HiMASS-j) used for specifying Hierarchical Control Flow Graph (HCFG) Models is described. The specification of HCFG Models in HiMASS-j is by visual interactive modeling through the use of graphical user interfaces and dialog boxes. HCFG Models are specified using two complementary hierarchical specification structures: one to specify the components that comprise a model and how these components are interconnected, and the other to specify the behaviors of individual atomic components. A simulation of a traffic intersection using HiMASS-j is …

Why Use Noise?, Denis G. Pelli, Bart Farell

Biomedical and Chemical Engineering - All Scholarship

Measuring the dependence of visual sensitivity on parameters of the visual stimulus is a mainstay of vision science. However, it is not widely appreciated that visual sensitivity is a product of two factors that are each invariant with respect to many properties of the stimulus and task. By estimating these two factors, one can isolate visual processes more easily than by using sensitivity measures alone. The underlying idea is that noise limits all forms of communication, including vision. As an empirical matter, it is often useful to measure the human observer’s threshold with and without a noise background added to …

Arginine To Glutamine Substitutions In The Fourth Module Of Xenopus Interphotoreceptor Retinoid-Binding Protein, Mark S. Braiman, Claxton A. Baer, Ellen E. Van Niel, Jeffrey W. Cronk, Michael T. Kinter, Nicholas E. Sherman, Federico Gonzalez-Fernandez

Chemistry - All Scholarship

Interphotoreceptor retinoid-binding protein (IRBP) is unusual for a lipid-binding protein in that its gene is expressed uniquely by cells of photoreceptor origin and consists of four homologous repeats, each coding for a module of~300 amino acid residues. All-trans retinol binding domains, which appear to be present in each module, are composed of conserved hydrophobic regions [Baer et al, Exp Eye Res 1998; 66:249-262]. Here we investigate the role of highly conserved arginines contained in these regions.

Partial Shape Matching Using Genetic Algorithms, Ender Ozcan, Chilukuri K. Mohan

Electrical Engineering and Computer Science - All Scholarship

Shape recognition is a challenging task when images contain overlapping, noisy, occluded, partial shapes. This paper addresses the task of matching input shapes with model shapes described in terms of features such as line segments and angles. The quality of matching is gauged using a measure derived from attributed shape grammars. We apply genetic algorithms to the partial shape-matching task. Preliminary results, using model shapes with 6 to 70 features each, are extremely encouraging.

An Efficient Parallel Algorithm For High Dimensional Similarity Join, Khaled Alsabti, Sanjay Ranka, Vineet Singh

Electrical Engineering and Computer Science - All Scholarship

Multidimensional similarity join finds pairs of multi-dimensional points that are within some small distance of each other: The 6-k-d-B tree has been proposed as a data structure that scales better as the number of dimensions in-creases compared to previous data structures. We present a cost model of the E-k-d-B tree and use it to optimize the leaf size. We present novel parallel algorithms for the similarity join using the E-k-d-B tree. A load-balancing strategy based on equi-depth histograms is shown to work well for uniform or low-skew situations, whereas another based on weighted equi-depth histograms works far better for high-skew …

The Coming Age Of Scarcity : Preventing Mass Death And Genocide In The Twenty-First Century, Michael N. Dobkowski, Isidor Wallimann

Books

The structure of the book is simple. The first part analyzes major forces having an impact on the survivability of civilization as we know it into the twenty-first century. It outlines the challenges we face, including overpopulation, pressure upon the land, migration, ecological damage, and social instability. In part two, we present more detailed discussion of the problem of scarcity and how it relates to conflict. The authors in this section argue that the current level of human activity is unsustain­able. They demonstrate that population growth in particular affects the natural world and can affect the social order and international …

Hydrogen And Oxygen Isotope Fractionation Between Brucite And Aqueous Nacl Solutions From 250 To 450°C, Peter Saccocia, J. S. Seewald, W. C. Shanks Iii

Geological Sciences Faculty Publications

Hydrogen and oxygen isotope fractionation factors between brucite and aqueous NaCl solutions (1000lnα_br-sw) have been calibrated by experiment from 250 to 450°C at 0.5 Kb. For D/H fractionation, 1000lnα _br-sw values are as follows: −32 ± 6‰ (250°C, 3.2 wt% NaCl), −21 ± 2‰ (350°C, 10.0 wt% NaCl), and −22 ± 2‰ (450°C, 3.2 wt% NaCl), indicating that brucite is depleted in D relative to coexisting aqueous NaCl solutions. These results are in good agreement with previous D/H fractionation factors determined in the brucite-water system, indicating that any effects of dissolved salt on D/H fractionation are relatively small, …

Climatology And Interannual Variability Of Wind Speeds In And Around Minnesota, Kevin J. Lawless, Katherine Klink

Journal of the Minnesota Academy of Science

Wind is receiving renewed attention as an energy resource. Unfortunately, many wind energy assessments are based on records that may not be representative of the long-term wind resource. To better evaluate wind energy potential in and around Minnesota, we analyze wind speeds from 1961 to 1990 for seven stations in the region at a height of about 6.1 m above ground level. We used hourly and three-hourly speed observations to develop a 30-year time series of mean monthly wind speeds, their maxima and minima, and the diurnal wind speed range. Simple linear regression was used to evaluate long-term trends in …
