Numeric Memory: Developing Representations
… (FTT) and the representational change account of numerical cognition, the present study introduced a single number recall task in which 39 preschool-aged children were asked to remember a quantity between 0 and 20 following a brief distractor task. Emphasizing accuracy of single number recall, …

Numeric Keyboard Layouts: An Ergonomic Approach
… study investigated the most effective method of numeric data entry, by means of a numeric keypad. The methods of numeric data entry were (a) two keypads with different numerical configurations, (b) two keypads with identical numerical configurations, and (c) one keypad with only a single …

Numeric Conversions Ameliorate the Framing Effect
People make judgments and decisions differently depending on whether information that prompts these judgments or decisions is presented in a positive or negative light. This bias is known as the framing effect. Previous research has shown that high numeracy, the ability to understand simple …

Symbolic-numeric programming in scientific computing
… notation, and the ability to express efficient numerical algorithms. To meet these goals simultaneously, languages use imperative surface syntaxes that mimic mathematical notation. However, mimicking does not make them the same—mathematics is declarative, pliable, and caters to exploratory human …

Hybrid Symbolic-Numeric Computing in Linear and Polynomial Algebra
In this thesis, we introduce hybrid symbolic-numeric methods for solving problems in linear and polynomial algebra. We mainly address the approximate GCD problem for polynomials, and problems related to parametric and polynomial matrices. For symbolic methods, our main concern is their complexity …

Selective catalytic reduction: testing, numeric modeling, and control strategies
… to NOx molar feed ratio were varied. A Simulink numeric model was created to examine the SCR transient phenomena. The Simulink numeric model showed in-catalyst ammonia and NOx concentration as a function of length in the direction of exhaust flow. This helped explain the SCR transient results. …

Data prefetch mechanisms for accelerating symbolic and numeric computation
Despite rapid increases in CPU performance, the primary obstacles to achieving higher performance in contemporary processor organizations remain control and data hazards. Primary data cache misses are responsible for the majority of the data hazards. With CPU primary cache sizes limited by clock …

Discovery through Numeric Strata: A Balance of Form and Aesthetics.
<p>This thesis is in support of my Master of Fine Arts exhibition in the Carroll Reece Museum at East Tennessee State University. It describes a body of work that strives for a balance of form and aesthetics. Chapter 1 charts how I refined my personal stylistic qualities. Chapter 2 gives a brief …

Comparative advantages of graphic versus numeric representation of quantitative data
… bar chart) representation--as opposed to numeric table--of a large, multivariate quantitative dataset (twenty variables with twenty four observations each), displayed and manipulated h interactively in a personal computer-based system. If the more complex observations made possible by …

Improving Steering Module Efficiency for Incremental Loading Finite Element Numeric Models
Engineers frequently use computerized numeric models to calculate and predict water levels and current patterns for rivers, bays, and other bodies of water. This computation often involves an iterative process known as incremental loading that can cause frustration and consume a lot of time. …

The Advantage of Numeric Uncertainty Information For Decision-Making With Two Thresholds
… make better decisions based on forecasts with numeric uncertainty estimates (e.g., 30%) compared to single value (deterministic) forecasts. Much of this work has focused on binary tasks. However, most real-world situations include more array of options. Advantages for uncertainty information …

Efficient Numeric Computation of a Phase Diagram in Biased Diffusion of Two Species
… equations for this system are evolved in time numerically, and the locus of this transition is determined via the presence of a stable state with coexisting regions of order and disorder. The Crank-Nicholson, nonlinear Gauss-Seidel, and GMRES algorithms used to solve the model equations are …

Analyzing and Manipulating Numeric Business Data: An Aid to Non-Expert Users (Spreadsheet Programs)
… of data it contains; i.e., the structure of numeric data is mapped onto the TF. TF can be used for presentation, storage, representation, and manipulation, though it is used mostly for presentation. Currently, spreadsheet programs which are based on the tabular framework are widely used in …

A first principles model and numeric solution methods for a system of self-organizing conductors
… retains the essential physics while still being numerically solvable. In this work, we develop a first-principles model of a system of electrically conducting particles which self-organizes to form complex electrical networks. The resulting model contains many non-linear interactions between the …
