International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / In order to reduce the ground segment equipment cost for small space missions, the French national space center (CNES) had the need to develop a CCSDS down-link interface board for low telemetry rates (< 1.5 Mb/s). This board performs frame synchronization and Reed-Solomon decoding. An important part of this design was the Reed-Solomon decoder development. In order to maintain low recurrent cost for this board, this decoder was realized in FPGA technology. Reed-Solomon decoding function, interleaving function (from 1 to 5) and virtual fill management are included in the same component. All set-up parameters are software programmable via the PCI bus, data and status are also available via the PCI bus under windows NT operating system. This paper presents the main features of this board and an overview of the Reed-Solomon decoder development.

This study is concerned with the representation of women in leadership positions in Solomon Islands. In particular, it explores the educational leadership experiences of women working in Solomon Islands' secondary schools. While much research to date has been carried out in the developed and developing countries, very little has been undertaken in Melanesian countries. As such, we know very little about women's experiences in educational leadership in Melanesia. Research data was gathered using qualitative methods. Specifically, interviews were conducted with eight women, five were deputy principals and three were Heads of Departments. All the participants were teaching in schools in an urban centre. Data gathered were analyzed using the thematic analysis approach. The data gathering was conducted in the Solomon Islands in October 2007. The key findings revealed a number of issues that impacted on the women's leadership in their respective schools. Findings include lack of self confidence, difficulties in balancing work and family, discriminatory attitudes and the influence of the cultural patriarchal norms on the attitudes towards women in leadership positions. Other key findings related to the nature of the organization, in this case, the school. This included a lack of initial preparatory and on - going professional development programmes and a lack of consultation in the decision making process. This study also found that while the women embraced the collaborative approach to leadership, the structural barriers through the hierarchical organization of the schools meant they could not lead the way they would like to.

This study used the qualitative semi-structured interview method to collect data to discover Solomon Islands parents' educational and career aspirations for their children and their perceptions of formal secondary education in the Solomon Islands with respect to their children's preparation for meeting these aspirations. In carrying out the research, four couples were selected as participants and categorized into two groups according to their educational attainment (well educated and less educated). What was found was that, although parents have educational and career aspirations for their children, not all parents were specific. The findings also suggested that the career aspirations parents have were mainly influenced by economic and social factors rather than internal factors. In relation to parents' perception of the formal secondary education system in terms of preparing students for work, the findings suggested parents have both a positive and low opinion of formal secondary education in the Solomon Islands. There was also a mixed feeling and point to the idea that there are other factors such as teachers and curriculum subjects that impacted on the perceptions of success or vice-versa of the secondary education system. The findings also suggested that while parents appreciate the vocational curriculum and education system as preparing students for work (than secondary education), preference however was given to secondary education first and foremost.

The particular focus is upon the significance of conversion to Christianity and subsequent Christian practice, in shaping social and cultural issues and practices in the 1990s. Women's lives, in particular those aspects concerned with kinship, are the lens through which historical changes are viewed. By juxtaposing the structures suggested by indigenous lifecycle categories and the differentiation inherent in individual biographical material, I try to reflect the regularities and continuities within Simbo society as well as the variability and unpredictability of sociality at any given moment. At the same time, the mutability of structure is reflected in the transformed significance of institutions and ostensibly similar practices. -- The period under scrutiny is that between c. 1900-1990, which covers social practices and events from immediately prior to pacification and the Methodist Mission's establishment in the New Georgia Group in 1902 up until the present. I argue that since pacification, the progressive development of indigenous Christianity has been the major determinant of Simbo responses to the world system. This is not to argue that pacification represented the first intrusion of Europe or the beginning of social transformations. Constructions of indigenous societies as having been static entities before contact with Europe are critiqued. Pacification, after more than a century of contact with Europe, had revolutionary implications because of its significance from local worldviews, as much as for its demonstration of British political "legitimacy". -- Christianity, then, cannot be divorced from the reality of political and economic subordination throughout the twentieth century. Nor, however, can it be simpHstically treated as merely the ideological face of expanding capitalism. Following J. Comaroff and J.L. Comaroff, I treat the non-material aspects of social life as being as significant as the material. From its earliest days, the Methodist Mission both facilitated and hampered the interests of government and traders. But it is not only mission personnel who are important here. Simbo people have consistently shaped and deployed their own Christian frameworks. If they never resisted it, they have certainly transformed what was imposed on them ninety years ago from ideology to lived hegemony. / Mode of access: World Wide Web. / xxiii, 378 leaves ill.

Med den stora utvecklingen inom teknologi ämnad för förfalskning av dokument och filer ökarbehovet av att kunna verifiera äktheten och integriteten hos digitala filer. Företaget "TheUndisputable Truth" har introducerat en metod för att lösa detta problem genom att användahashkoder i en blockchain. Istället för att spara hela dokument online, sparas en pseudounikhashkod av filen. Hashkoden är en kryptografiskt genererad representation av filen sompraktiskt taget endast kan skapas från originalfilen och är extremt svår att återskapa utan att hatillgång till filen. En minimal ändring i filen genererar en helt annan hashkod, vilket gör detomöjligt att avgöra filernas likhet utifrån hashkoderna.Projektet syftade till att utveckla en metod som bevarar säkerheten hos hashkoderna samtidigtsom den kan detektera och redovisa små avvikelser i innehåll mellan en fil och en krypteradversion av en fil med mycket liknande innehåll i systemet, med frågeställningen huruvida det varpraktiskt och möjligt. För att uppnå detta undersöktes användningen av felkorrigeringstekniker,specifikt Hammingkoder och Reed Solomon.Initialt undersöktes applikationer av felkorrigering på texter. Hammingkoder är till sin naturbegränsade till att detektera och lokalisera ett fel, men visade att felkorrigering var applicerbart.Reed Solomon kunde hantera ett fel per två extrapunkter av information. Dock uppstod problemom en felaktighet försköt texten, vilket resulterade i att allt efter felet betraktades som felaktigt,då Reed Solomon-algoritmen är designad för meddelanden av bestämd längd. För att lösadetta delades texten upp i segment som avgränsades av ett nyckeltecken och ordnades efterbitarnas innehåll, vilket resulterade i att förskjutningsfel begränsades till små segment av texten.Detta bedömdes att tillfredsställa kraven på algoritmen.När det gäller bilder undersöktes möjligheten att hantera beskurna bilder med hjälp av en metodsom inom projektet kallades Reed Solomon snapping. Metoden grundades i att sparasegmenterade bitar och testa en något större bit än de sparade bitarna, för att sedan användaReed Solomon för att fastställa positionen för beskärningen om den fanns med. Dock leddedenna metod till enorm datalagring och betydande tidsåtgång, vilket gjorde det orealistiskt attuppnå projektets mål med den befintliga teknologin. Möjligtvis är det applicerbart på andraområden, till exempel identifiering av huruvida ett kapitel ingår i en bok.Frågeställningen bedömdes besvaras jakande för texter, då algoritmen klarade målet förprojektet. Däremot kunde detta inte sägas för bilder, som kräver vidare forskning.

This thesis absorbs and reflects on Choiseul Island responses and caution towards the making of anthropological knowledge. Initial interests that can easily become familiar to anthropology as research topics such as village life, local cosmology and local alternatives to cosmologies of climate and ecology, make way here for another activity of working through Choiseul responses to anthropology. In taking seriously the precautions and the considerations of people in this Solomon Islands locality, anthropology is invited to put a stoppage to practices that it would consider ordinary and part of anthropological knowledge making. This impasse for the discipline is outlined and explored in various chapters, in which usual styles of ethnography and topic-making take formation in respect of a Choiseul world that does not fit easily into encapsulation by anthropology. Effects for the discipline of anthropology are given consideration, within a wider view of imagining how an alternative anthropology in the vernacular can also entail an obviation of anthropology itself in favour of new forms of cultural sensitivity.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Range Safety Systems are used for destruction of a vehicle should a malfunction cause the vehicle to veer off course. All vehicles launched into space require implementation of a Range Safety System. For years the IRIG receivers have been used with relatively good success. Unfortunately, the IRIG receivers do not provide a high level of security. High alphabet receivers were later developed for use on the big launchers (Atlas, Delta, Titan, etc) and the manned missions (Shuttle) to provide added security. With the IRIG based system, several problems have occurred resulting in the loss millions of dollars worth of equipment. Due to the problems that have occurred it has become apparent that there is a need for a more secure, low cost, type of range safety receiver. This paper describes the design and development of the prototype EFTS system. Mission critical parameters are discussed including selection of the encryption and forward error correction algorithms. Actual measured performance including message error rate characteristic is presented.
