An investigation of the Four Area Curriculum Extension and Enrichment Model for Gifted Education as viewed through the Cartesian, Socialist and Deep Ecology epistemologies
… it was deemed necessary to evaluate the Four Area Curriculum Extension and Enrichment model in terms of three epistemological focuses: Cartesian, Socialist and Deep Ecology. Reasons for the selection of these three epistemologies are discussed after which the traditional Cartesian, homunculus …

An economic appraisal of agricultural development and adjustment possibilities for a low income farm area
… profit-maximizing plans for a low income farm area and to indicate the magnitude of resource adjustment required to meet this optimum. The study set out to develop optimum plans for the individual farm units and for the area using the variable resource programming procedure. This procedure …

Effective modeling of throughput time in semiconductor assembly processes
We develop discrete event simulation (DES) models of a semiconductor assembly process capable of predicting average throughput time (TPT) within 6% of factory-floor measured average TPT. This represents a significant improvement over current DES models in the semiconductor industry, which commonly …

Establishing uranium migration parameters for the Indian Springs Range
… in the environmental parameters used to model DU migration in arid soils through extensive soil characterization; and evaluated potential horizontal migration of DU through close examination of erosion tracts traversing the target area. Model error reduction was achieved by developing …

Engine modelling for virtual mapping. Development of a physics based cycle-by-cycle virtual engine that can be used for cyclic engine mapping applications, engine flow modelling, ECU calibration, real-time engine control or vehicle simulation studies.
After undergoing a study about current engine modelling and mapping approaches as well as the engine modelling requirements for different applications, a major problem found to be present is the extensive and time consuming mapping procedure that every engine has to go through so that all control …

Modello bayesiano per la riduzione dell'incertezza nella previsione delle piene del fiume Reno
… last years to reduce uncertainty in hydrological modeling predictions. The principal sources of uncertainty are provided by input errors, for inaccurate rainfall prediction, and model errors, given by the approximation with which the water flow processes in the soil and river discharges are …

Clovis Technology and Settlement in the American Southeast
… that traditionally-accepted, western-centric models do not fully explain Clovis technological characteristics and settlement patterns in the region. My second chapter presents the results of a 40 square meter block excavation on the Topper site (SC) hillside where a buried Clovis assemblage …

Fraction Models That Promote Understanding For Elementary Students
<p>This study examined the use of the set, area, and linear models of fraction representation to enhance elementary students' conceptual understanding of fractions. Students' preferences regarding the set, area, and linear models of fractions during independent work was also investigated. This …

ADVANCING MULTIPHASE PROCESS DEVELOPMENT WITH HYBRID PHYSICS-BASED – MACHINE LEARNING MODELS
… To develop predictive and generalizable models, it is essential to capture both reaction kinetics and the complex transport phenomena that influence system performance. This thesis presents a hybrid modelling framework for reactive multiphase processes, demonstrated on a liquid-liquid …

Characterization and Modeling of the Ionomer-Conductor Interface in Ionic Polymer Transducers
… (SWNT), polyaniline (PANI) powders, high surface area RuO2, and carbon black electrodes. The DAP provided the tool which enabled us to study the effect of electrode architecture on performance of ionic polymer transducers. The DAP allows the variation in the electrode architecture which enabled us …

Flow routing in the parallel pipes of a combined sewer system
A parallel pipe model has been constructed and successfully applied to a twin pipe sewer system. The model predicts flow and level for each of the parallel pipes and deals with the complex behaviour which occurs at cross-connections.<br/><br/>The model DUPPERS is an enhancement of the single pipe …

Beamforming and scan pattern performance evaluation of rotating maritime multi-beam phased array surveillance radar
… This dissertation aimed to provide a simulation model to test and evaluate the effect of different beamforming and scan patterns on the detection performance of different possible targets in the maritime environment per antenna rotation. MATLAB, with various Phased Array Toolbox objects, was used …

Hydrological factors influencing the ecology of riverbed breeding birds on the plains' reaches of Canterbury's braided rivers : a thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy in the University of Canterbury
… numbers also occur on lowland riverbeds. These areas are subject to existing or planned water developments which may have negative impacts on the conservation of these habitats and bird species. The principal goal of this study was to add to the information necessary to conserve lowland riverbed …
