Multi-Level process integration of heat pumps in a non-continuous processing site
… In New Zealand, many industries operate in a non-continuous manner, creating challenges in the accurate application of these existing Heat Integration methods. This thesis presents a multi-level process integration method for heat pump and thermal storage retrofit on non-continuous industrial …

Mathematical modelling of the onset of transformation from austenite to pearlite under non-continuous cooling conditions
… for three different cooling conditions; namely, continuous, semi-continuous and non-continuous cooling conditions. The predictions were consistent in all cases and compared favourably against other methods which have been employed frequently frequently to estimate the transformation start …

A One Pass Line-Following Algorithm for Linear Feature Extraction
… roads), irregular double lines (rivers), and non-continuous lines of any pattern (streams, railroads); (2) it can ignore most common noise found in scanned raster data; (3) it has high speed performance (running in time linearly proportional to the number of interior black pixels). The …

Creation of nonlinear density gradients for use in internal wave research
A method was developed to create a nonlinear density gradient in a tank of water. Such gradients are useful for studying internal waves, an ocean phenomenon that plays an important role in climate and ocean circulation. The method was developed by expanding on the two-tank system currently used to …

Development of a miniature, continuous measurement, stochastic perturbation gas chromatograph
… traditional chromatographic measurements are non-continuous. The first part of this thesis explores the application of stochastic system identification techniques applied to chromatography to enable continuous chromatographic measurements, multiplexing of instrument components, and the ability …

CLASSIFICATION OF HIGH IMPEDANCE FAULTS, INCIPIENT FAULTS AND CIRCUIT BREAKER RESTRIKES DURING CAPACITOR BANK DE-ENERGIZATION IN RADIAL DISTRIBUTION FEEDERS
… classifies the event as normal operation, continuous and non-continuous arcing events (C.A.E. and N.C.A.E.). Additional information from the supervisory control and data acquisition (SCADA) can be used to precisely identify the event. The proposed method is meticulously tested on the IEEE …

Open-Source tools for practical heat integration and utility system evaluation
… and real-world cost savings, especially for non-continuous processes. This thesis addresses these challenges by developing two complementary open-source tools that bridge the gap between advanced process integration methods and practical industrial implementation. The novel contributions in …

Wearable Lab and BioFab on body : towards closed-loop bio-digital human augmentation
… are currently limited to one-time use, are non-continuous and don't provide flexibility in choosing which biomarker they sense. We believe that the future for wearable biosensors lies in going beyond specific sensing capabilities and becoming a wearable "lab" on body, where a small device …

Continuous manufacture of enabling formulations for a poorly soluble compound using hot melt extrusion technology
… and the associated high costs arising from its non-continuous processing structure and inefficiency, the industry welcomes ideas which generate increased efficiency and cost-effectiveness. A concept which hot melt extrusion processing embodies.<br/><br/>The work presented in this thesis sought …

Assessing the spatiotemporal variation of phytoplankton biomass in Nandoni reservoir in the Vhembe District (South Africa) using LANDSAT satellite imagery
… system are time consuming, expensive, and non–continuous, therefore, Remote Sensing technologies are qualitative for monitoring the status for water quality in large scale and low cost. The aim of this study was to assess the spatial and temporal variation of phytoplankton biomass in …

A study comparing outcomes of appendectomy between HIV-infected and HIV-negative patients
… using the Chi-Squared or Fisher's exact test for non-continuous variables, and non- parametric ANOVA and Wilcoxon ranked sum test for continuous variables. A P-value less than 0·05 was considered statistically significant. Results: The study group comprised 134 patients; 18 (13.4 %) tested …

Dna Profiling of Captive Roseate Spoonbill (Ajaia Ajaja) Populations As a Mechanism of Determining Lineage in Colonial Nesting Birds.
… and Sedgwick County (Kansas) zoos revealed a non-continuous distribution of allele frequencies, consistent with the effects of a population bottleneck. Allelic frequencies also differed significantly between the isolated zoo populations. Although extra-pair copulations were suspected and …

Laminated Sediments of Loch Ness, Scotland: Indicators of Holocene Environmental Change
… that the hypothesis was correct, and that a non-continuous chronology had been obtained, spanning the period ca 9000 to 1500 BP. Lamination thickness data derived from recent sediments was compared with meteorological data, especially rainfall, in order to test the hypothesis that prevailing …

Low-Density Cluster Separators for Large, High-Dimensional, Mixed and Non-Linearly Separable Data.
… in high-dimensional spaces. This requires continuous observations; thus, to extend the applicability of the proposed algorithms to mixed datasets, methods for producing an appropriate continuous representation of datasets containing non-continuous features are investigated. The exact …

Understanding extreme behavior by optimizing tail dependence with application to ground level ozone via data mining and spatial modeling
… how our method can be modified to deal with non-continuous covariates such as precipitation. Lastly, we seek to model how a set of primary drivers varies spatially over a study region. We utilize data from 160 EPA stations in 13 US states plus the District of Columbia. We model the parameters …

A space-constrained resource-constrained scheduling system for multi-story buildings
… The model adopts a procedure to schedule non-continuous activities using variable length segments along the typical floors. In addition, the model allows for adjusting the initial defined resource demand pools for different activities to account for any modifications that may occur to the …

The Impact of Loss Aversion and Market Sentiment on Implied Volatility Skews.
… within the standard option pricing models. Non-normal distribution functions, leverage effects and non-continuous trading markets which follow a jump diffusion process, can all result in distortions in the implied volatility surface. Furthermore, a limitation of arbitrage due to herding and …

The Importance of Multiple Study Areas in Landscape Genetics: The American Black Bear in the Rocky Mountains
… (IBD) after removing landscape effects were non-significant in nearly all study areas. Five study areas had significant landscape genetic models (p <0.05, partial Mantel tests). These results suggest landscape features were a better predictor of gene flow than IBD, which re-affirms previous …
