A response surface approach to data analysis in robust parameter design
… obvious that combined arrays and a response surface approach can be effective tools in our quest to reduce (process) variability. An important aspect of the improvement of quality is to suppress the magnitude of the influence coming from subtle changes of noise factors. To model and control …

A response surface approach to the mixture problem when the mixture components are categorized
… of this paper is to show how standard response surface designs and polynomial models can be used for estimating the response to mixtures of the k mixture components. The experimentation is concentrated in an ellipsoidal region chosen by the experimenter, subject to the constraints placed on the …

Teleworker Well-Being in COVID-19 as a Function of Change in the Work/Home Boundary: A Multilevel Response Surface Approach
… better well-being. Using multilevel response surface analysis (MRSA), which enabled illustration of these complex associations in a more nuanced manner than is possible via either change scores or moderation analyses, I found that maintaining higher work/home integration both before and after …

Reflection And The Distance Language Learner
… notions of the 'good' language learner, the deep approach to learning and autonomous learning in the context of adult, part-time, distance language learning. This group of learners is under-represented in the research literature. The research takes an exploratory-interpretative approach. Open …

Response surface designs and analysis for bi-randomization error structures
… may dictate the necessity to run response surface experiments in a bi-randomization error control format of which the split plot design is a special case. A bi-randomization scheme allows for certain factor levels to be applied at random to large experimental units with the remaining factor …

Quantum dynamical study of Si(100) surface-mounted, STM-driven switches at the atomic and molecular scale
… microscope (STM)-controllable, Si(100)(2x1) surface-mounted switches of atomic and molecular scale. The first example considers the switching of single H-atoms between two dangling-bond chemisorption sites on a Si-dimer of the Si(100) surface (Grey et al., 1996). The second system examines …

Student success in an introductory engineering course : an investigation of approach to learning and cultural capital
The construct of approach to learning has proved to be powerful in explaining differences in students' experiences of learning in higher education. However this construct does not explain the impact that students' socio-economic background has on their experiences of higher education. For this …

Assessment for learning in higher education
… in assessment for learning through a case study approach. By examining closely the assessment practice in one higher education institution in the UK, the thesis presents a number of original contributions to the literature, knowledge base and practice of assessment for learning.<br/><br/>The …

THEORETICAL DETERMINATION OF THE YIELD CURVE FOR UNSATURATED SOILS
… is presented. Finally, the Modified State Surface Approach (MSSA) is adopted to calibrate the unsaturated soil parameters on constant water content (undrained) tests and determine the shapes of yield curves for unsaturated soils. A modification to BBM is also proposed to handle the …

Techniques for Stochastic Implicit Surface Modelling and Rendering
Implicit surfaces are a powerful shape primitive for computer graphics. This thesis focuses on a shape modelling approach which generates synthetic shapes by the specification of an implicit surface generating function that has random properties. This type of graphic object can be called a …

Adapting Response Surface Methods for the Optimization of Black-Box Systems
… require many model evaluations, making this approach too computationally expensive. To limit the number of experimental runs, it is common practice to model the departure as a Gaussian stochastic process (GaSP) to develop an emulator of the computer model. One advantage for using an emulator …

Relating college students' learning approach to their quality of learning outcome
… the predictor variables of Locus of Control, Approach to Learning, and Metacognition, and their relationship (singly and in combination) with the quality of learning outcome (structural complexity and depth of cognitive performance). Rotter's Locus of Control Scale (Rotter, 1966), Biggs's …

Interactive media in distance learning for UK farmers: the countryside disc
… interactions with the Disc. Each farmer's approach to learning changed as he or she worked through the program, and was clearly related to the learning outcomes for that person. The Disc demanded a deep approach: two farmers who attempted to use a surface approach were unable to continue. …

An exploratory investigation of the approaches to learning of accounting students studying toward a professionally accredited post-graduate programme at the University of Cape Town
… learning has resulted in interest in student approaches to learning. The aim of this paper is to provide a preliminary investigation into the approaches to learning of accounting students in the context of a South African university by sampling students studying a professionally accredited …

Addressing the learning of chemistry at undergraduate level: towards the development of independent learning
… interaction with learning supports and their approaches to learning at university. In this study, varied and changing student profiles have been observed. It has been shown that factors including student ‘interest’, ‘learning responsibilities’, ‘student attendance’ and their ‘approaches to …

Theoretical and simulations-based modeling of micellization in linear and branched surfactant systems
… (i) formation of surfactant monolayers at surfaces and interfaces, and (ii) self-assembly into finite aggregates (micelles) in the bulk solution beyond the critical micelle concentration (cmc). This concentration-dependent phase behavior induces changes in solution properties. For example, …

The researcher was interested in the strategies adopted by students when faced with their normal learning tasks in a teachers college setting. What determined the strategies that students used? How effective were these strategies? …
