The aim of this essay is to show how both Treasure Island and Black Sails depict master narratives that are mainly influenced by imperialist ideology. The essay analyzes elements present in both the novel and the television series that reflect imperialist practices such as “othering,” propaganda, and exploitation. The aim of this essay is also to underline the plurality of voices created by various narratives of marginalized people present in the two sources. By analyzing the perspective and social organization of minority groups such as children, gay men, and people with disabilities, this essay demonstrates how the narratives of marginalized people can be both subversive and complementary to the master narrative.

Future solar sail and solar power satellite missions require deployment of large and lightweight flexible structures in space. One option is to spin the assembly and use the centrifugal force for deployment, stiffening and stabilization. Some of the main advantages with spin deployment are that the significant forces are in the plane of rotation, a relatively simple control can be used and the tension in the membrane or web can be adjusted by the spin rate to meet the mission requirements. However, a successful deployment requires careful development of new control schemes. The deployment rate can be controlled by a torque, applied either to a satellite in the center or by thrusters in the corners, or by deployment rate control, obtained by tether, spool braking or folding properties. Analytical models with only three degrees of freedom were here used to model the deployment of webs and membranes for various folding patterns and control schemes, with focus on space webs folded in star-like arms coiled around a center hub. The model was used to investigate control requirements and folding patterns and to obtain optimal control laws for centrifugal deployment. New control laws were derived from the optimal control results and previously presented control strategies. Analytical and finite element simulations indicate that the here developed control laws yield less oscillations, and most likely more robustness, than existing controls. Rotation-free (RF) shell elements can be used to model inflation or centrifugal deployment of flexible memebrane structures by the finite element method. RF elements approximate the rotational degrees of freedom from the out-of-plane displacements of a patch of elements, and thus avoid common singularity problems for very thin shells. The performance of RF shell elements on unstructured grids is investigated in the last article of this thesis, and it is shown that a combination of existing RF elements performs well even for unstructured grids. / QC 20100729

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: This thesis describes the development of attitude sensors required for the Attitude Determination and Control System (ADCS) for a Cubesat. The aim is to find the most suitable sensors for use on a small picosatellite by implementing miniaturised sensors with available commercial-off-the-shelf (COTS) technology. Specifically, the algorithms, hardware prototypes, software and filters required to create accurate sensors to determine the 3-axis orientation of a CubeSat are discussed. / AFRIKAANSE OPSOMMING: Hierdie tesis beskryf die ontwikkeling van oriëntasiesensors wat benodig word vir die oriëntasiebepaling en -beheerstelsel (Engels: ADCS) van ’n CubeSat. Die doelwit is om sensors te vind wat die geskikste is om in ’n klein picosatelliet te gebruik, deur miniatuursensors met kommersiële maklik verkrygbare tegnologie (Engels: COTS technology) te implementeer. Daar word in die bespreking veral aandag geskenk aan die algoritmes, hardewareprototipes, programmatuur en filters wat benodig word om akkurate sensors te skep wat op hul beurt 3-as oriëntasie van die CubeSat kan bepaal.

Food Not Bombs provides free meals in public spaces and protests government and corporate policies that harm the poor and homeless. Homes Not Jails is a sister group of Food Not Bombs that opens up unused houses and government buildings to provide housing for homeless residents. During the period 1988-1995, two mayors, progressive Art Agnos (1988-1991) and conservative Frank Jordan (1992-1995), mass-arrested members of Food Not Bombs for distributing food in city parks without a permit, handing out over 1,000 arrest and citations to members of the group in that eight year period. While squatting would seem to be a graver offense than distributing free food, Homes Not Jails was treated far more leniently by city officials during the Jordan administrations. I trace the difference in treatment of the two groups to the fact that Food Not Bombs engages in anarchist direct action in public space, while Homes Not Jails does so in private residences. The public nature of Food Not Bombs made them a visible threat to order to both Agnos and Jordan and one they had to confront and stop. While both mayoral administrations persecuted Food Not Bombs, they treated the organization in different ways, which derived from different conceptions of the cause of homelessness. Agnos saw homelessness as a result of structural inequalities and economic conditions and viewed state welfare programs as the only way to address the problem. In response to Food Not Bombs he tried to incorporate them into the broader charity apparatus of the state, and when that failed he used the police to force them into "negotiated management" with the city Jordan saw homelessness as a criminal and public safety problem and wanted to use the police to clean and reclaim the city for wealthier residents and tourists. Jordan saw Food Not Bombs as a threat to public order and tried to use his police force to exclude the group from public space. / Committee in charge: Gerald Berk, Chairperson, Political Science; Joseph Lowndes, Member, Political Science; Deborah Baumgold, Member, Political Science; Michael Dreiling, Outside Member, Sociology

This exploratory, mixed-methods study investigated the relationship between information literacy and critical thinking. The research question guiding the first portion of the study was: How do information literacy and critical thinking relate in undergraduate students conducting academic research? Using two standardized assessments, the study assessed the information literacy and critical thinking skills of a small population of college students from a private, university in Texas. The correlational analysis of the scores from the two assessments showed a statistically significant, positive, moderate correlation. The study also explored the likelihood of gender differences in cognitive processing using information literacy and critical think skills assessments. The independent samples t-tests for both assessments demonstrated no statistically significant differences between female and male participants. Finally, a qualitative component comprised of a questionnaire provided context to the assessment scores through items requesting information on participant source selection priorities via the three middle stages of Kuhlthau's information search process model as well as their criteria for selecting sources of information. Though only a small number of the participants completed the questionnaire, the responses highlighted areas of interest for future research.

This master thesis studies alternative energy sources for maritime shipping in Sweden. With current climate goals, and a need for change, the maritime sector currently undergoes intense transitions. For shipping companies to lower their carbon footprint, the need to replace non decarbonised fuels is hence critical. With numerous alternatives, currently being developed, actors are phasing obstacles regarding which energy source that is most mature in terms of technical readiness as well as how adequate it will fulfil current climate goals. This study will analyse four different energy sources, liquid hydrogen (LH2), electro-methanol (emethanol), electro-ammonia (e-ammonia) and wind (sails), and answer which out of these energy sources will be most suitable for actors to adapt. To answer this question, the Technological Innovation System framework has been utilised, and the results has been applied to some chosen climate target actions developed by Swedish authorities. The findings proved that e-methanol currently is most mature and has reached most alignment with current climate goals, followed by LH2/wind and lastly e-ammonia. / Detta examensarbete studerar alternativa energikällor för fraktfartyg i Sverige. Med nuvarande klimatmål, och ett behov av förändring, genomgår den maritima sektorn intensiva omställningar. För att rederier ska kunna sänka sitt koldioxidavtryck är behovet att ersätta icke koldioxidneutrala bränslen därför stort. Med ett flertal alternativ, som för närvarande är under utveckling, står aktörer inför hinder angående vilken energikälla som är mest redo gällande teknikmognadsgrad samt hur adekvat den kommer att uppfylla nuvarande klimatmål. Denna studie kommer att analysera fyra olika energikällor, flytande väte (LH2), elektro-metanol (e-metanol), elektro-ammoniak (e-ammoniak) och vind (segel), och ta reda på vilka av dessa energikällor som är mest lämpad för aktörer att använda sig av. För att svara på denna fråga har ramverket Technological Innovation Systems använts och resultaten har tillämpats på några utvalda klimatmålsåtgärder som tagits fram av svenska myndigheter. Resultaten visade att e-metanol för närvarande är mest mogen och har nått mest anpassning till nuvarande klimatmål, följt av LH2/vind och slutligen e-ammoniak.
