582	Semiotic anomalies in English, as second language learners of immigrant parents acquire first time literacy Snelgar, Elizabeth Claire Gien 11 1900 (has links) Research has shown that literacy acquisition and the ultimate realisation of literacy, comprehension of the written text requires more than the ability to decode individual words. This study brings together a synthesis of current research on early language acquisition, language structure, vocabulary development and its intrinsic underpinning of comprehension in monolinguals thereby providing a theoretical framework for a comparative study of limited English proficient learners (LEP’s)/English language learners (ELLs) acquiring first time literacy with the attendant vocabulary deficits and age appropriate decoding skills. A quantitative and qualitative study examines the statistical differences between reading, vocabulary, rapid automatic naming (RAN/decoding) and comprehension when a learner born of foreign parents acquires first time literacy in a language other than the language spoken at home. The study isolates and specifies an at risk educational minority through the identification of a hidden comprehension deficit (HCD). In summarising the main findings from the literature review and the empirical investigation, an “at risk educational minority” was identified and isolated through the identification of the HCD. The envisioned outcome was achieved and the hypothesis accepted. / Educational Studies / M. Ed.

583	Development of Sensors and Microcontrollers for Underwater Robots Jebelli, Ali January 2014 (has links) Nowadays, small autonomous underwater robots are strongly preferred for remote exploration of unknown and unstructured environments. Such robots allow the exploration and monitoring of underwater environments where a long term underwater presence is required to cover a large area. Furthermore, reducing the robot size, embedding electrical board inside and reducing cost are some of the challenges designers of autonomous underwater robots are facing. As a key device for reliable operation-decision process of autonomous underwater robots, a relatively fast and cost effective controller based on Fuzzy logic and proportional-integral-derivative method is proposed in this thesis. It efficiently models nonlinear system behaviors largely present in robot operation and for which mathematical models are difficult to obtain. To evaluate its response, the fault finding test approach was applied and the response of each task of the robot depicted under different operating conditions. The robot performance while combining all control programs and including sensors was also investigated while the number of program codes and inputs were increased.
