RADAR Based Collision Avoidance for Unmanned Aircraft Systems

Unmanned Aircraft Systems (UAS) have become increasingly prevalent and will represent an increasing percentage of all aviation. These unmanned aircraft are available in a wide range of sizes and capabilities and can be used for a multitude of civilian and military applications. However, as the number of UAS increases so does the risk of mid-air collisions involving unmanned aircraft. This dissertation aims present one possible solution for addressing the mid-air collision problem in addition to increasing the levels of autonomy of UAS beyond waypoint navigation to include preemptive sensor-based collision avoidance. The presented research goes beyond the current state of the art by demonstrating the feasibility and providing an example of a scalable, self-contained, RADAR-based, collision avoidance system. The technology described herein can be made suitable for use on a miniature (Maximum Takeoff Weight \u3c 10kg) UAS platform. This is of paramount importance as the miniature UAS field has the lowest barriers to entry (acquisition and operating costs) and consequently represents the most rapidly increasing class of UAS

Language maintenance and shift in the Greek community in Johannesburg

Summaries in English and GreekKeywords in English and GreekThis thesis explores the phenomenon of language shift and maintenance in the Greek community of Johannesburg, which is the largest Greek community in South Africa. The main aim of the study is to provide an account of the factors which assist in maintaining the Greek language which is under pressure from English, the dominant official language in the country. This study draws on the theoretical and methodological frameworks established in the many studies conducted on the Greek communities in the USA and Australia. The Greek community has played a significant role in assisting to shape the development of South Africa. Up until the 1980s, they were subject to discrimination from the host society; consequently, many immigrants lived together in certain suburbs and founded their own churches, clubs and schools. These factors contributed greatly to the retention of their language and culture. Since the late 1980s, the discriminatory attitude of the host society toward the immigrant communities has decreased notably, and subsequently, there has been an increased integration and assimilation into the host society. The process of assimilation has resulted, inter alia, in an increased use of English, the dominant language of the host society, consequently the retention of the mother tongue has declined. A number of factors were identified as playing an important role in the maintenance of Greek: education, religion, family, language loyalty and socio-cultural activities; and, to a lesser extent, media and overseas visits. Education has played a key role in maintaining the language, in particular through the establishment of Greek day and afternoon schools. Despite a preference for bilingual church services, the Greek Orthodox Church continues to play a vital role in the maintenance of Greek. The family, loyalty towards the language and culture and a notable pride in being Greek, and participation in socio-cultural activities contribute significantly to the maintenance of the Greek language. Despite a marked shift towards English in the younger generation, the future of Greek in South Africa may be characterized by relatively stable bilingualism, provided that current trends continue.Η παροφςα μελζτθ πραγματεφεται το φαινόμενο τθσ αλλαγισ και διατιρθςθσ τθσ ελλθνικισ γλϊςςασ ςτθν ελλθνικι κοινότθτα του Γιοχάνεςμπουργκ, θ οποία αποτελεί τθν μεγαλφτερθ κοινότθτα ςτο Γιοχάνεςμπουργκ.

Language shift and maintenance in the Portuguese community of Johannesburg

The aim of the study is to provide an account of the present state of Portuguese in the Johannesburg Portuguese community, and to identify factors influencing the maintenance of, and shift from the mother tongue. South African society necessitates a knowledge and daily use of English, and sometimes Afrikaans. Literacy and proficiency in the Portuguese mother tongue is therefore rapidly decreasing, especially amongst the third generation. Despite this decline, certain factors play a role in maintaining Portuguese. The most important factors in the maintenance of the mother tongue are education, cultural activities, contact with Portugal, parental influence and positive attitudes. If measures are not taken, and an awareness created within the community of the need to create a situation of stable bilingualism, the Portuguese language will continue to be eroded.0 objectivo desta tese e analisar o nivel actual da lingua portuguesa, na comunidade Portuguesa em Joanesburgo, e identificar os factores que influenciam a manutenc;ao e ou o afastamento da lingua materna.

Water dynamics about selected monosaccharides in solution

Includes bibliographical references.The solubility of molecules in water is governed, amongst other things, by the inherent properties of the solute molecules and water molecules. Water molecules are able to simultaneously form hydrogen bonds as donors and acceptors and thus have unique properties as solvent molecules. These properties influence how water interacts with solute molecules. The mechanism of hydrogen bond exchange plays a role in the hydration of solute molecules. A key to understanding some of the biological processes lies in understanding how solutes interact with water. In this thesis, the hydration of monosaccharides has been studied using computational methods. The hydration structure is elucidated by pair distribution functions and spatial distribution functions. Hydrogen bond exchange dynamics were investigated on the basis of the molecular jump mechanism. Evaluation of the hydrogen bond exchange dynamics reveals two possible pathways. The first pathway corresponds to the molecular jump mechanism reported in literature. The second pathway is described. This pathway provides details on the water-hydroxyl interactions taking place around the monosaccharides. It is shown that the presence of a primary alcohol on pyranose based molecules induces a configuration that allows favourable interactions between water molecules and hydroxyl groups on the sugar molecules. A region of high water density is formed between the primary alcohol, ring oxygen and the hydroxyl on the anomeric carbon. This is due to rotations by water molecules from one hydroxyl, to the adjacent hydroxyl on the sugar molecule. It is not only the presence of the primary alcohol that plays a role in the hydration of the monosaccharides. The relative position of the hydroxyl on the anomeric carbon is shown to create a topology conducive of hydroxyl to hydroxyl hydrogen bond exchanges. The hydration of monosaccharides is rationalised by these effects

Quantifying The Training and Match-Play External and Internal Load of Elite Gaelic Football Players

The current investigation quantified the training and match-play load of elite Gaelic football players across a two-season period using global positioning system technology (GPS), rating of perceived exertion (RPE) and sessional rating of perceived exertion (sRPE). Total weekly workload variables were collected across GPS, RPE, and sRPE across thirty-six elite Gaelic footballers (mean ± SD, age: 26 ± 5 years; height: 177 ± 8 cm; mass: 81 ± 7 kg) from one elite squad during a two-season observational period. External training load variables included: Total distance (m), High speed running (m; ≥ 17.1 km·h −1 ), Sprint distance (m; 22 km·h −1 ), Accelerations (n), Average metabolic power (W·kg−1 ), High-power distance (m; ≥ 25 W·kg−1 ). Internal load variables included: sRPE and RPE. Repeated measures ANOVA were used to understand the differences in loading patterns across phases, position, and week types when significant main effects were observed a Tukey’s post hoc test was applied and standardized effect sizes were calculated to understand the practical meaning of these differences. When total weekly loading across phases was considered total load was significantly greater in club 1 and provincial 1 with these phases showing the highest loading for players when compared to all other phases (p ≤ 0.001; ES: 2.95–7.22; very large). Furthermore, in-season 1 was greater for total loading when compared to in-season 2 and both championship phases (p ≤ 0.05; ES: 0.47–0.54; small). Total distance in training was greater during preseason 1 when compared to all other phases of the season (p ≤ 0.001; ES: 2.95–7.22; very large). During the in-season period, training based total distance was higher during provincial 1 when compared to other phases with similar trends across all measures (p ≤ 0.005). Finally, a positional profile for load measures was observed, with weekly context (match or non-match) having an impact on the internal and external loading players experienced across phases. The current data provide useful information for practitioners on the training periodization currently present within the elite Gaelic football training process. Specifically, the data provide positional profiles of loading across weekly and segmented phased of an elite Gaelic football season. These data can increase understanding as to the periods of increased and decreased loading across different phases of an elite Gaelic football season, while providing a framework for future analysis concerning Gaelic football periodization
