HOW TO MAKE A RUGGEDIZED SSD

Budd, Chris 11 1900 (has links)
SSDs are now commonplace in all types of computing from consumer laptops to enterprise storage systems. However, most of those SSDs would not survive in environments with extreme temperatures or high shock and vibration such as found in embedded and military systems. The problems in this space are more than just mechanical; they involve all aspects of the design including electrical and even firmware. A combination of all three engineering disciplines is needed to provide a robust ruggedized SSD product.

Dynamic Architectural Simulation Model of YellowCar in MATLAB/Simulink Using AUTOSAR System

Soltani, Saeed 01 November 2016 (has links) (PDF)
The YellowCar at the professorship of computer engineering of TU Chemnitz is a demonstration vehicle. The car is equipped with multiple networked Electronic Control Unit (ECU)s. There are regular software and hardware updates. Before introduction of any new update, it is essential to test the behavior of the car. This can be done through simulation. Since the majority of the ECU in YellowCar are AUTOSAR based, several AUTOSAR simulation tools can be used to do so. However non-AUTOSAR ECU applications can still not be simulated in these tools. Moreover simulating with such tools need the whole application to be implemented and also very expensive. Simulink is one of the most powerful tools for the purpose of Model-in-the-Loop (MIL) testing which is a popular strategy in the embedded world. The scope of this Master thesis is analyzing the YellowCar and its architecture to develop a dynamic Simulink architectural model that can be modified and extended to facilitate future updates. The outcome of this thesis is an implementation of a model for the YellowCar which allows both AUTOSAR and non-AUTOSAR ECUs to be simulated as one system. Also the model supports extension by easy addition of new modules like ECU or sensor through a graphical user interface.

Du territoire d'approvisionnement au territoire culturel : pétroarchéologie et techno-économie du silex Grain de mil durant l’Aurignacien dans le Sud-ouest de la France / From provisioning territories to cultural territories : petroarchaeology and techno-economy of Grain de mil flint during Aurignacian in South-West France

Caux, Solène 23 October 2015 (has links)
La caractérisation des matières premières lithiques est un important moyen d’étude des territoires paléolithiques, permettant d’inférer les modes de déplacement et d’organisation des groupes humains. Le Bassin aquitain est une des provinces archéologiques les mieux documentées d’Europe. Pourtant, certains matériaux depuis longtemps reconnus au sein des collections archéologiques, restent mal identifiés (origine géographique, unicité…). C’est en particulier le cas d’un type de silex dénommé « Grain de mil » par les préhistoriens. Pour combler cette lacune, ce travail s’organise en deux temps :- Une étude pétroarchéologique de ce matériau, axée sur sa caractérisation et la détermination de son origine géographique et géologique. Cette première phase du travail a permis de définir le Grain de mil comme un matériau typique de Charente-Maritime puisque sa formation est liée à l’anticlinal de Jonzac. Elle montre aussi que les critères de sa caractérisation, principalement issus de l’analyse des faciès sédimentaires, peuvent être appliqués lors de l’étude pétro-techno-économique d’une collection archéologique.- Une caractérisation techno-économique des modes de gestion de ce matériau à l’Aurignacien ancien et récent dans les sites nord-aquitains. A l’Aurignacien ancien, les groupes circulent à travers l’ensemble du Bassin aquitain au cours de grands déplacements saisonniers ; il semble que l’exploitation du Grain de mil témoigne d’une faible circulation dans le Nord-ouest du Bassin. A l’Aurignacien récent au contraire, les territoires d’approvisionnements ont centrés sur le Nord du Bassin aquitain mais ouverts à l’Ouest voire au Nord ; le Grain de mil serait alors au coeur de larges réseaux de circulation des groupes. Les moteurs d’évolution des sociétés à l’origine de ces changements de stratégie de déplacement sont ensuite discutés, testant pour cela le rôle des facteurs environnementaux et humains. / Characterising lithic raw materials is an important means of studying palaeolithic territories, allowing modes of mobilityand the organisation of human groups to be deduced. The Aquitaine Basin is one of the best-documented archaeologicalregions of Europe. However, certain materials have long been recognised within archaeological collections without theirgeographic origin or even their uniqueness being clearly demonstrated. This is particularly the case with a specific type offlint, which prehistorians call “Grain de mil”. In order to address these shortcomings, this work was carried in two phases:- a cross-disciplinary study of this material, focusing on its petroarchaeological characterisation and its geographicand geological origins. This initial phase of analysis lead to the definition of Grain de mil flint as a material typical ofthe Charente-Maritime as its formation is tied to the Jonzac anticline. It also shows that criteria for itscharacterisation, which stem mainly from the sedimentological analysis, can be applied to the petro-technoeconomicstudy of an archaeological assemblage.- a techno-economic characterisation of the management of this material during the Early and Late Aurignacian,from northern Aquitaine sites. During the Early Aurignacian, groups move seasonally across the Aquitaine Basin;exploitation of Grain de mil flint seems to indicate little circulation in the north-west of the Basin. In contrast, duringthe Late Aurignacian, provisioning territories centre to the north of the Aquitaine Basin, but open to the west andalso to the north. Grain de mil then appears to be at the heart of large-scale networks of circulations. Finally, theunderlying forces driving these strategic changes in mobility patterns are discussed, evaluating the role of bothenvironmental and human factors.

Capital social e o programa mulheres mil no âmbito do instituto federal de educação, ciência e tecnologia do Maranhão / campus Imperatriz (MA) / Capital social and Mulheres Mil Program under the Federal Institute of Education, Science and Technology Campus of Imperatriz in state of Maranhão

Widglan Barbosa de Sousa Nunes 06 May 2016 (has links)
O programa Mulheres Mil tem como finalidade promover a inclusão social e a melhoria da qualidade de vida das mulheres em situação de vulnerabilidade social por meio da formação no ensino profissionalizante. O objetivo geral desta pesquisa é verificar o capital social, a inserção ao mercado de trabalho e a prática empreendedora das alunas egressas do programa Mulheres Mil, no âmbito do Instituto Federal de Educação, Ciência e Tecnologia do Maranhão, campus Imperatriz. A pesquisa é descritiva, com abordagem quantitativa, delineamento de levantamento dos dados e estudo de caso. A amostra constitui-se de 134 alunas egressas dos cursos de camareira e de construção civil/acabamento e pintura dos períodos de 2013 e 2014, respectivamente. Utilizaram-se, como instrumentos de coleta de dados, os questionários de identificação da amostra; o integrado para medir capital social do Banco Mundial; e o do programa Mulheres Mil. O tratamento dos dados obtidos e analisados foi realizado pelo programa Microsoft Excel, do pacote Office (2013) e Statistical Packageof Social of Science (SPSS), utilizado na análise da correlação entre os dados com o teste estatístico Qui-Quadrado. A caracterização dos dados sociodemográficos apresenta um grupo de mulheres na idade adulta, predominantemente entre 31 e 40 anos, casadas, com emprego informal e baixa escolaridade. Os resultados referentes ao capital social apontam que a maioria participa de pelo menos um grupo, principalmente religioso; tem um círculo de amizade pequeno; vive com certa desconfiança nas pessoas; e participa de ações coletivas, porém com baixa frequência. As mulheres se sentem inseguras em relação à violência, mas mesmo com essa adversidade consideram-se felizes, com a autoconfiança elevada, principalmente após a realização do curso. As respostas do questionário referente ao programa Mulheres Mil mostram que o Programa mudou a vida delas para melhor, tanto no aspecto pessoal como profissional. Embora vivam em sua maioria em ambiente familiar conturbado elas têm apoio familiar e os cursos propiciaram o conhecimento de seus direitos, dando mais autoconfiança no trabalho e, consequentemente, melhoria nos rendimentos, apesar de a maioria ainda trabalhar em casa, ou próximo de suas casas, com vendas autônomas, afazeres domésticos e prestação de pequenos serviços. / The Mulheres Mil Program aims to promote social inclusion and to improve the quality of life of women in situations of social vulnerability, by offering training in vocational education, enabling improvements in the quality of workmanship and potentially influencing the students in improvement of life for their families and their communities. The purpose of this study is to present the social results of Mulheres Mil Program under the Federal Institute of Education, Science and Technology Campus of Imperatriz in state of Maranhão. The overall objective of the research is to ascertain the social capital as well as the integration into the labor market and the perception of benefits by the former students of Mulheres Mil Program under the Federal Institute of Education, Science and Technology of Maranhão / Campus Imperatriz. The type of research will be descriptive with qualitative approach and are used as the design of the data collection with questionnaires. The sample consists of 134 former students. of Maid courses and Construction / Finishing and Painting period 2013 to 2014 the Thousand Women Program of the Federal Institute of Maranhão Campus Imperatriz. The instruments used for research were the questionnaires Sample Identification; Integrated Questionnaire for Measuring Social Capita World Bank and questionnaire to the graduates students of the Thousand Women Program. The processing of the data obtained and analyzed was performed using Microsoft Excel Office suite (2013) and the Statistical Package of Social of Science (SPSS) used to analyze the correlation between the data with the statistical test Chi-square, as well performing the Cronbachs alpha test for reliability analysis of the data. The characterization of demographic data showed a group of women with a predominance in adulthood, married with most informal employment and low education. The results of the questionnaire on the social capital found that the vast majority attend at least one group, mainly religious, presented small circle of friends, living with a certain distrust in people, large membership in collective action but infrequently, women feel very insecure with regard to violence and even with that adversity can feel happy, with high confidence especially after the completion of the course. The results of the questionnaire on the Women Program Thousand prevailed that the program has changed their lives for the better, both personally and professionally, although they have a troubled family environment, had family support, Program courses have left the most knowledgeable women of their rights with more confidence to work, is consequent an improvement in earnings, although most still work at home or close sales, household chores, small service.

Développement de stratégies de désherbage dans les cultures de millet perlé grain, fourrager et sucré (Pennisetum [L.] R. Br.)

Cuerrier, Marie-Edith 13 April 2018 (has links)
Field studies were conducted in 200 5 and in 200 6 at Saint-Augustin-de-Desmaures (Québec) to détermine the effects of two herbicides (s-metolachlor/benoxacor, pendimethalin), applied either pre or early postemergence, and weed harrowing, on control of annual grass weeds and on yield of grain, forage and sweet pearl millet hybrids. Results indicate that s-metolachlor/benoxacor applied preemergence is phytotoxic to pearl millet. Ail other chemical treatments produced a good control of annual grass weeds and generated good yields. In early postemergence, s-metolachlor/benoxacor controlled barnyard grass in a more effective way than pendimethalin. Weed harrowing did not control annual weeds in an effective way, resulting in important yield losses. An integrating weeding strategy including a false seed bed technique and the application of s-metolachlor/benoxacor in early postemergence or of pendimethalin in preemergence or early postemergence represents a solution to the weeding problem in pearl millet. / Des essais ont été mis en place en 2005 et 2006 à Saint-Augustin-de-Desmaures (Québec) afin de préciser les effets de deux herbicides (s-métolachlore/benoxacor, pendiméthaline), appliqués en prélevée ou en postlevée hâtive, et du désherbage mécanique, sur la répression des monocotylédones annuelles et sur le rendement du millet perlé grain, fourrager et sucré. Les résultats indiquent que le s-métolachlore/benoxacor appliqué en prélevée est phytotoxique pour le millet perlé. Les autres traitements chimiques ont produit un bon désherbage des monocotylédones annuelles et ont procuré des rendements très satisfaisants. En postlevée hâtive, le s-métolachlore/benoxacor a réprimé l'échinochloa pied-de-coq plus efficacement que la pendiméthaline. Enfin, le désherbage mécanique a produit un désherbage insuffisant, provoquant d'importantes pertes de rendement. Une stratégie intégrée de désherbage incluant un faux semis et l'application du smétolachlore/ benoxacor en postlevée hâtive ou de la pendiméthaline en prélevée ou en postlevée hâtive constitue une solution au problème de désherbage du millet perlé.

South African naval diplomacy since 1994

Manganyi, Calvin 04 1900 (has links)
Thesis (MMil)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Since the beginning of naval power, navies have been used by their states as instruments of foreign policy. In South Africa, the political transition since 1994 originated the evolution of the country’s foreign policy. Accordingly, foreign policy has implications for the South African Navy (SAN). Traditionally, navies have three main roles, namely: military, policing and diplomatic, roles. This study only focuses on the diplomatic role of the navy, termed naval diplomacy. In this regard, the SAN is the custodian of South African naval diplomacy. The purpose of this study is to investigate and theoretically appraise the nature and scope of South African naval diplomacy since 1994. The study has two objectives: firstly, it seeks to outline the most salient features of South Africa’s foreign policy, post-1994, as the framework for naval diplomacy; and secondly, it seeks to analyse and describe how the SAN has utilised naval diplomacy, namely: maritime coercion, naval cooperation, international maritime assistance, and international conflict resolution and management, in pursuit of South Africa’s foreign policy objectives. The research methodology is a qualitative descriptive analysis, using a literature study, factual data sources, and interviews, as techniques. Both primary and secondary sources are consulted. This study makes an original contribution to the gap in the literature on South African naval diplomacy. In this regard, with the procurement of the recent ships and submarines, South African naval diplomatic capabilities have improved significantly. It is for this reason that the SAN is currently instrumental in maritime coercion in the region, particularly deterrence against piracy and other maritime insecurity issues. The SAN is also immensely involved in naval cooperation. In terms of international maritime assistance, the SAN does not only assist other countries in search and rescue missions, but also empower them. It also plays a vital and evolving role in international conflict resolution and management. The, however, SAN faces several hindrances including ageing equipment and ships (such as strike craft and hydrographic survey vessel); lack of patrol vessels and sea lift capability; loss of skilled personnel; and other challenges. / AFRIKAANSE OPSOMMING: Sedert die ontstaan van vlootmagte het state vlote as buitelandse beleidsinstrumente aangewend. Die politieke oorgang in Suid-Afrika in 1994 het tot ʼn evolusie in die land se buitelandse beleid aanleiding gegee, wat ook gevolge vir die Suid-Afrikaanse Vloot (SAV) ingehou het. Tradisioneel het vlote drie hooffunksies, naamlik ʼn militêre, ʼn polisiëring en ʼn diplomatieke funksie. Hierdie studie fokus slegs op die diplomatieke funksie van die vloot, waarna verwys word as vlootdiplomasie, en die SAV se rol as die ‘bewaarder’ van Suid-Afrikaanse vlootdiplomasie. Die doel van hierdie studie is om ondersoek in te stel na die aard en omvang van Suid-Afrikaanse vlootdiplomasie sedert 1994 en dit aan die hand van relevante teoretiese beginsels te beoordeel. Hieruit voortspruitend is twee doelwitte: eerstens om die wesenskenmerke van Suid-Afrika se buitelandse beleid na 1994 as raamwerk vir vlootdiplomasie te gebruik; en tweedens om die wyse waarop vlootdiplomasie ter ondersteuning van Suid-Afrikaanse buitelandse beleidsdoelwitte aangewend is, te beskryf en te ontleed met spesifieke verwysing na maritieme dwang, samewerking tussen vlootmagte, internasionale maritieme hulpverlening, en internasionale konflikresolusie. Die navorsingsmetodologie is 'n kwalitatiewe beskrywende ontleding, gegrond op 'n literatuurstudie, feitlike bronne, en onderhoude. Beide primêre en sekondêre bronne is in die proses geraadpleeg. Hierdie studie is 'n oorspronklike bydrae om die leemte in die literatuur oor die Suid-Afrikaanse vlootdiplomasie aan te spreek. Na die onlangse aanskaffing van nuwe skepe en duikbote, het die SAV se diplomatieke vermoëns aansienlik verbeter. Die gevolg is dat die SAV tans ʼn wesenlike bydrae met betrekking tot maritieme dwang in die streek speel, veral wat teen-seerowery en ander maritieme veiligheidsbedreigings betref. Die SAV is ook baie betrokke in maritieme samewerking. Wat internasionale maritieme hulp betref, het die SAV ander lande met soek en reddingsoperasies bygestaan en ook bemagtig. Die SAV lewer ook ‘n groeiende bydrae tot internasionale konflikresolusie en bestuur. Maar die SAV staar ook verskeie uitdagings in die gesig wat die volgende insluit: verouderde toerusting en skepe (soos aanvalsvaartuie en die hidrografiese opmetingskip); 'n gebrek aan patrollievaartuie en 'n see-verplasingsvermoë; verlies van opgeleide personeel, en verskeie ander uitdagings.
