A study on Chinese learners' IELTS preparation efforts

Yu, Yuqing, 余玉青 January 2014 (has links)
In recent decades, autonomous learning has been a hot issue in the field of second language teaching and learning and the previous studies on autonomous learning have made great progress. However, the researches on the individual efforts affecting achievements of major English language proficiency tests from the cognitive perspectives of autonomous learning are still relatively rare. On the basis of the review of literature on learner autonomy at home and abroad, the present study aims to investigate Chinese learners’ IELTS preparation efforts under the guidance of the cognitive theory with the participants of English-medium tertiary institutions for graduate or undergraduate degrees who got high score(at least 7 or above) in IELTS within 2 years and answer what these Chinese learners have done to maximize their IELTS scores to apply for postgraduate programmes in English medium universities autonomously and why they could undertake these efforts to maximize their IELTS scores. Semi-structure interviews on autonomous learning were conducted to find out IELTS preparation experiences. In terms of the data analysis results, the dissertation tries to provide the present or future graduate degree applicants during their IELTS preparation with some suggestions and implications for enhancing recognition on IELTS taking and help language educators better advise these students on undertaking proper preparations for the language challenge in their overseas studies. / published_or_final_version / Education / Master / Master of Education

Assessment of Normal force testing to measure adhesion at organic-inorganic interfaces in organic optoelectronic devices

Das Gupta, Hrishikesh 11 1900 (has links)
Organic photovoltaic (OPV) devices are emerging as a reliable source of energy due to their combination of unique features. Though desired for their flexibility, low cost, light weight, large area fabrication compatibility and eco-friendly nature, these devices face numerous challenges in achieving high performance and stability. The organic-electrode interface specifically plays a key role in controlling device stability. Recent studies have revealed that the stability is heavily affected by the adhesion of the organic-electrode interface. Measurement of adhesion at these interfaces, however, is a challenging task. In this study, Normal Force Adhesion testing was assessed to determine its suitability for organic devices. In this approach, force is applied perpendicular to the substrate, over the entire surface area of one device (9 mm2) until delamination occurs. In addition to the extracted force-distance curves, images of the interfaces before and after each experiment and a real-time, in-situ video taken from a lateral perspective were examined. All three of these critical pieces of information are necessary to obtain a complete picture of the success of a Normal test. A statistical assessment has been made of the testing apparatus, using many samples (> 50) of one metal - organic combination, Al-Alq3 - an archetypal combination for organic electronics. In addition, five other metal-organic combinations widely used in organic electronic devices, have been chosen to assess the Normal force approach. Due to the ease of testing a large number of samples, Normal force testing does appear to be a viable approach to examining interfacial adhesion, though care must be taken in the experimental design to avoid common experimental failures. Based on the results, a few recommendations have been made to improve the utility of the adhesion testing system for rapid quality testing of organic devices. / Thesis / Master of Applied Science (MASc)

Statistické řízení a regulace výrobního procesu / Statisticall Process Control

Neugebauer, Tomáš January 2008 (has links)
This dissertation deals with utilisation of the method SPC in the field of engineering production. The work is outlined as instructions for introduction and usage of SPC in production. The reason for introduction of SPC is the effort to improve the quality constantly. The systematic approach was used for implementation of the very method so that the efficiency of the introduction is as high as possible. The dissertation contains three fundamental parts – theoretical part, suggestion of the process of the solution and practical implementation.

Nástroj pro vyvolávání chyb založený na infrastrukuře Systemtap / A Fault Injection Bug Hunting Tool Based on Systemtap

Zelinka, Martin January 2011 (has links)
This work describes different methods of fault injection, the principles of system calls in operating system Linux and the Systemtap tool. The main aim of thesis is design and implementation of the application that work on the principle of fault injection into the system calls using Systemtap tool. Implemented application automatically identifies the existing system calls with the error return values, which are then replaced the original system calls return value.

Membrane module development for water recovery from humid gas

Matthee, Francois January 2020 (has links)
>Magister Scientiae - MSc / Over the past 5 years, South Africa has been experiencing a severe drought. This has caused industrial and agricultural processes, to compete for a limited supply of water. Since the economy relies mostly on agricultural activities, water consumption by industrial processes is taking its toll. One of these processes is the introduction of wet flue gas desulphurization (FGD) treatment at Eskom coal fired power stations. This dissertation explores the possibility of using membrane technology as a means of water recovery after the coal combustion flue gas has been treated with wet FGD. A lab-scale permeance testing system was specially built and modified to have complete thermal control of the environment inside the system. The permeance testing system produced a gas, similar to that of a wet FGD treated flue gas, which was then tested. A tubular lab-scale membrane module was designed and produced for the permeance testing system. The permeance figures of both Nitrogen gas and water vapour were determined for the membrane used in module production. These figures coincided with figures provided by the supplier, which warranted successful permeance testing. After success of the lab-scale testing, the data was used to design and develop a pilot-scale membrane module. This module was designed to meet pre-determined requirements as set forth by the project team. Producing lab-scale membrane modules helped identify and address possible problems in pilot-scale module design. This lead to the successful design and construction of a pilot-scale membrane module that could be used to recover the water that is needed to run the wet FGD process.
