Some Solutions to a Lens Model With Applications to Warm-Core Eddies
<p>A model of lens-shaped anticyclonic eddies based on nonlinear shallow water equations is developed. The model is a three-layer fluid and allows for one asymmetric mode as well as specified environmental flows. The solution scheme is a polynomial expansion of the field variables. When inserted …

"Doing and Viewing Gender" : a lens-model approach to the communicative construction of gender in task-oriented groups
… this dissertation focuses on applying a joint model and a corresponding method suited for integrating the many dispersed empirical studies on doing and viewing aspects of gender. An application of Brunswik’s lens-model (Brunswik, 1956) to communication research provides the basis for the …

Fitting binary lens gravitational microlensing events with example-based algorithms
Fitting binary lens models to gravitational microlensing event is currently a time consuming and labour-intensive process. Example-based algorithms more commonly used in the field of data mining were applied to simulatded and observed light curves in order to facilitate the fitting of a …

An attempt to measure the time delays of three gravitational lenses
… and analysis of two seasons of gravitational lens monitoring using the Very Large Array (VLA) at 8.5 GHz. The campaign monitored five gravitational lenses, GL1608, GL1830, GL1632, GL1838, and GL2004 from 24 January 2002 until 18 September 2002, and from 21 May 2003 until 29 January 2004. In …

An analysis of the work roles of chief executive officers in small furniture manufacturing firms
… firms. The approach used in this study to model the judgment of the CEOs is called "Brunswiks Lens Model." This lens model approach provides a quantified, descriptive summary of the way an individual weighs and combines information. The research design utilized in this study is a fixed 2⁸ …

Modeling auditor judgment in nonstatistical sampling
… tests. The research will utilize Egon Brunswik's Lens Model to provide mathematical representations of the auditor's judgment process. Correlational statistics will be used to assess judgment accuracy, agreement (consensus) , and auditor "self-insight" into his decision process. The study will …

Forecasting corporate performance
… accuracy that is expected to be achieved when a model replaces the human decision-maker in the selection of cues. The second major purpose is to examine the information overload phenomenon to provide research evidence to determine the point at which additional information may contaminate …

Instabilities of volatile films and drops
… "octopi" instability, we develop a theoretical model for evaporation of a pure liquid drop on a thermally conductive solid substrate. This model includes all relevant physical effects, including evaporation, thermal conductivity in both liquid and solid, (thermocapillary) Marangoni effect, vapor …

Relevance Thresholds: A Conjunctive/Disjunctive Model of End-User Cognition as an Evaluative Process
… the perceived effectiveness of such systems. The Lens Model of user cognition serves as the foundation for design and interpretation of the study; earlier research in problem solving, decision making, and attitude formation also contribute to the model and analysis. A self reporting instrument …

Statistical analyses of gravitational microlensing probability densities
Gravitational microlensing is a powerful modelling tool, that is essential in accurately understanding the lensing behavior of astronomically strong lensed objects. Using Joachim Wambsganss micro-magnification maps, we discuss the creation of a Monte-Carlo tool that can determine the likelihood for …

Modeling the effect of trend information on human failure detection and diagnosis in spacecraft systems
… system design tool. This tool includes models of human decision making in order to evaluate system design tradeoffs with regard to human performance. An experiment was conducted to evaluate the effect of trend information displays on human decision making performance. Decision latency …

From Irritants to Satisfaction: A Model of a Theory of Meaning Applied to Reading the‘Sabbath of the LORD’ Motif In Exodus 16
… composite postpositivist theory of meaning and a model that can explain the phenomenon of the so-called vicious circle in interpretation. I propose a theory of interpretative relativity, and a model based on the telephoto effect of an actual zoom lens. According to this theory and the zoom lens …

Single cancer cell detection with optofluidic intracavity spectroscopy
… the spectra of HSA cells motivated a new optical model of the cell loaded F-P cavity. The OFIS spectra of individual cells from canine HSA and canine lymphoma cancer cell lines exhibit relatively uniformly spaced multiple transverse modes repeated in each free spectral range of a microfluidic F-P …
