The purpose of this study is to explore the integration of the iPad as a learning and teaching technology into the Foundations Program at the two Higher Colleges of Technology in Fujairah: Fujairah Men’s College (FMC) and Fujairah Women’s College (FWC) in the United Arab Emirates. The new technology was introduced to enable the Program’s teachers and students to support their teaching and learning of English as a foreign language. Specifically, the study investigates how these teachers and students used the iPad’s technical affordances to create pedagogical affordances designed to construct and promote English language teaching and learning. It also examines the challenges they faced in doing so, the types of tasks and activities for which the new technology was used. Finally, it sheds light on the limitations of the iPad as perceived by these users as well as other relevant issues arising from the launch of the technology in the two colleges. The data for the research were drawn from class observations, interviews and surveys. Six Foundations Program classes were observed, five teachers were interviewed, five more teachers were asked one written research question, and ten students were asked another written research question. In addition, two surveys – one for the teachers and one for the students – were conducted to obtain further data. The study finds that the Foundations Program’s teachers and students used the iPad’s technical affordances effectively to construct activities that largely enhanced their teaching and learning by making it more interesting, and engaging. In doing so, they faced challenges that they tried to resolve and which had some impact on their teaching and learning. In addition, the study has identified a number of issues relating to the use of the iPad in the Program as well as what these iPad users perceived as limitations of the new technology. Finally, the study stresses the importance of conducting a pilot scheme prior to any proposed rollout of a new educational technology and suggests longitudinal studies with larger and more representative samples to assess and measure any contributions or lack thereof the iPad makes to the teaching and learning of English as a foreign language. I believe that the study contributes to the area of TESOL and mobile learning by its focus on the rich experience of two higher education colleges using the iPad as a teaching and learning technology in classes of Arab learners and by highlighting the challenges the teachers and students at these two colleges faced in their attempt to integrate the new technology in their context as well as what they perceived as the technology’s pedagogical and technical limitations. Another important contribution of the study is the exploration of other issues arising from the use of the iPad in the Fujairah colleges’ teaching and learning environment. It is also important to note that study findings could provide insights into the integration of the iPad into the foundations programs of the other fifteen colleges in the Higher Colleges of Technology system given the similarities these colleges share with the two Fujairah colleges. Neither would it be an exaggeration to suggest that these findings could also provide an insight into the experience of using the iPad in similar learning environments in other UAE educational institutions.

[pt] Os projetos de capacidade de suporte de estacas estão baseados em dados de ensaio de campo de maneira direta ou indireta. Devido a sua praticidade, os métodos empíricos são amplamente utilizados. No Brasil os métodos de Decourt e Quaresma (1978, 1982) e de Aoki e Velloso (1975) se destacam. Este trabalho procura avaliar o uso de dados de SPT e CPT para estimativa de parâmetros geotécnicos necessários na previsão de capacidade de suporte de estacas através de métodos teóricos. São apresentadas e avaliadas formulações empíricas de estimativa de parâmetros para materiais granulares e materiais argilosos. Outro elemento importante na previsão da capacidade de suporte é o estado de tensões atuante em torno da estaca que é analisado através de considerações a respeito do coeficiente de empuxo. Finalmente, são mostrados alguns resultados de provas de carga para a análise da seleção de parâmetros e do estado de tensões, além de uma avaliação dos métodos empíricos de previsão de capacidade de suporte. / [en] The main objective of this thesis is to discuss the applicability of in-situ tests like the Standard Penetration Test (SPT) and the Cone Penetration Test (CPT) to determine directly the design parameters to predict the bearing capacity of pile foundations. In case it will be considered the use of empirical correlation to indicate the mechanical properties of the soil in terms of shear resistance, and the application of these values directly in the classic formulation based on the theory of equilibrium limit to evaluate distinctly the shaft and the base resistance of piles. Adaptations of these values will be proceeded considering aspects related with the non-linear behavior of the soil; the mechanism of load transfer and the influence of the constructive aspects.The results obtained through this new methodology will be compared with experimental results, obtained from static and dynamic load tests and also with other empiric procedures that use the results obtained from in-situ tests to evaluate directly the bearing capacity of deep foundations.

Master of Science / Department of Architectural Engineering and Construction Science / Darren D. Reynolds / Highly expansive soils can severely damage the foundations which they support. These damages create unnecessary maintenance cost to the owner and can be detrimental to the building superstructure. Post-tensioned ribbed mat foundations are commonly used in light commercial construction in areas in the United States that have highly expansive soils. Mild reinforced ribbed mat foundations are rarely used in these areas. This report investigates why post-tensioned ribbed mat foundations are more common in these areas than mild-reinforced ribbed mat foundations. The approach to this investigation is a design example which designs and compares the two foundation types. The design example is a typical 2-story office building located in Dallas, Texas, which is an area that has highly expansive soils. First, a post-tensioned ribbed mat foundation is designed for the office building. Next, a mild-reinforced ribbed mat foundation is designed for the same building. A comparison is done between the two foundations based on serviceability, strength requirements and construction costs. The findings in the comparison is that post-tensioning is a more economical and constructible method. Using mild-reinforcement requires the use of shear reinforcement in the ribs which is not typical in foundation design and construction and is less economical, and additional reinforcement in the slab is needed to resist bending stresses which is also less economical. The finding of the report is that of the two foundation types, the post-tensioned ribbed mat foundation is the better design based on the three areas of interest listed above. The use of a mild-reinforced mat foundation would require construction procedures that are not typical and would be less economical.

Fundações por estacas escavadas com trado mecânico têm sido largamente empregadas para cargas de pequeno e médio porte. Como o processo executivo não consegue evitar a deterioração das propriedades do solo in situ no fundo da escavação, a única parcela confiável de resistência é aquela referente ao atrito lateral. No entanto, a ponta dessas estacas, muitas vezes, atinge estratos com resistência relativamente elevada e não consegue aproveitar as qualidades do estrato. O presente trabalho visou o estudo do comportamento desse tipo de estaca no perfil geotécnico típico da cidade de Londrina, através da execução de provas de carga dinâmica em 16 estacas de 0,25 m de diâmetro e 12 m de comprimento, sendo três estacas tradicionais e 13 estacas com ponta modificada. Foram feitas, também, provas de carga estática em duas estacas tradicionais, inspeção das pontas de todas as estacas e determinação dos parâmetros de resistência do solo. Os resultados mostraram que todas as modificações pesquisadas permitiram a utilização da carga estrutural nominal das estacas e que a mais eficiente foi a do tipo que promoveu a melhoria do solo na ponta com a adição de um estabilizante de solo. / Auger pile foundations have been widely employed for light to medium loads. As the executive process can’t avoid the degradation of the bottom excavation in situ soil properties, the only reliable resistance is a lateral friction parcel. However, these tip piles, many times, reaches relatively resistant strata and can’t take advantage from these strata qualities. The present paper seems study the performance of this kind of piles in typical geotechnical profile of Londrina, by dynamic load tests on 16 piles with diameter equal 0,25 m and length of 12 m, when three traditional piles and on thirteen kinds with tip modification. Were made, also, static load tests on three traditional piles, tip investigation on all piles and soil resistance parameters determination. The results shaw that all modifications researched was able to use the nominal structural load of piles and that the more efficient of them was the soil improvement by soil stabilizer addition.
