Underground mining of the Kiirunavaara iron mineralization is causing large-scale deformation of the hangingwall of the orebody. To understand and possibly predict future deformation, a structural model of the hanging wall and a good understanding of the petrophysical and mechanical properties of the constituent rocks is necessary. This thesis presents results from the study of Anisotropy of Magnetic Susceptibility (AMS), magneto-mineralogy, fracture frequency (F/m), rock quality (RQD), rock strength (Point Load) and P-wave velocity and anisotropy of the rocks from the hanging wall, as well as seismic reflection surveying and gravity modelling. The results are combined into a structural model of the hanging wall and further used for analysis of the correlation between petrophysical and rock mechanical parameters.In total, 76 samples from 12 outcrops and 295 samples from three drillcores in the hanging wall have been included in the AMS study. Axial and diametrical P-wave velocity was measured on 25 water-saturated samples and 156 samples were used for the Point Load tests. F/m and RQD data for the drillcores already existed. The drillcores are located along the eastern end of the seismic profiles and consist of both crystalline and sedimentary rocks.A high degree of magnetic anisotropy observed in the crystalline rocks indicates a low degree of metamorphism. AMS data also indicates the presence of a magnetic foliation in the rocks. The dip of the magnetic foliation plane (F) and the degree of magnetic anisotropy (Pj) measured in samples from outcrops was plotted as iso-maps and shows that both F and Pj decreases towards the east, which was confirmed by data from the drillcores. The decrease in both parameters is primarily a reflection of a change in rock type, but is also changing within the crystalline rock sequence.A good correlation (r > 0.6) between Pj, and F and RQD, and F and F/m was observed in one drillcore for both crystalline and sedimentary rocks; and between the shape parameter (T) and F/m in crystalline rock in another drillcore. This suggests the AMS parameter may be used as an indicator of rock mechanical properties. AMS data was also correlated to joint strike orientations and it was concluded that AMS can also be used to predict joint orientation.Two parallel reflection seismic profiles were shot within the town of Kiruna i order to locate deformation zones and lithological boundaries in the hangingwall. No deformation zones were found, but five seismic reflectors corresponding to five lithological boundaries were located, and their strike and dip calculated. The result of the seismic survey was used to constrain the gravity model, as was density measurements of 230 samples from the drillcores. The gravity model has a depth of three km, and indicates that the crystalline rock in the hanging wall can be separated into two parallel N-S trending blocks. / Godkänd; 2011; 20111021 (maimos); DISPUTATION Ämnesområde: Tillämpad geofysik/Applied Geophysics Opponent: PhD Satu Mertanen, Geological Survey of Finland, Åbo Ordförande: Professor Sten-Åke Elming, Institutionen för samhällsbyggnad och naturresurser, Luleå tekniska universitet Tid: Måndag den 19 december 2011, kl 10.00 Plats: F531, Luleå tekniska universitet

La sclérose latérale amyotrophique [SLA] est une pathologie idiopathique à issue fatale caractérisée par la dégénérescence progressive et sélective des motoneurones du système nerveux central et périphérique. La SLA n’est pas exclusivement identifiée comme une maladie de la voie pyramidale, mais considérée plus largement comme une pathologie neurodégénérative multisystème. L’étude des mécanismes posturaux dans cette population n’a pas fait l’objet d’une grande attention. Dans ce travail de thèse, une exploration en imagerie cérébrale multimodale (imagerie en tenseur de diffusion [DTI] et morphométrie basée sur le voxel [VBM]) est proposée chez des patients SLA avec instabilité posturale [AIP] et stables [SIP] en vue de vérifier l’intégrité morphologique et structurelle des régions corticales et sous-corticales posturales. La comparaison entre les sujets contrôles et les patients SLA a démontré une augmentation significative du volume de la substance grise au niveau du noyau caudé chez les patients stables (SIP vs contrôle p<0,001 ; SIP vs AIP p<0,01). L’évaluation structurelle a révélé une diminution de la fraction d’anisotropie [FA] au niveau de l’aire motrice supplémentaire [AMS] dans les deux groupes de patients par rapport aux contrôles (contrôle vs SIP p<0,05 ; contrôle vs AIP p<0,001). Au niveau du noyau caudé, le groupe AIP a présenté une diminution de la valeur de la FA par rapport aux sujets contrôles (p<0,001) et aux sujets SIP (p<0,05). Ainsi, ces résultats contribuent à une meilleure caractérisation et compréhension des atteintes corticales et sous corticales des régions qui interviennent dans la posture chez les patients SLA. / The Amyotrophic Lateral Sclerosis [ALS] is an idiopathic pathology with a fatal outcome. It is characterized by a progressive and selective degeneration of motor neurons in the central and peripheral nervous system. ALS is no longer exclusively identified as a disease of the pyramidal pathway, but it is considered more broadly as multisystem neurodegenerative pathology. However, the analysis of postural processes in these patients has not been well studied in the literature. Multimodal brain imaging (Diffusion Tensor Imaging [DTI] and Voxel Based Morphometry [VBM]) exploration was performed for ALS patients with postural instability [AIP] and without postural instability [SIP] to test the morphometric and structural integrity of postural cortical and subcortical regions. A significant increase of gray matter in caudate nucleus volume has been noticed for stable patients (SIP vs controls p<0.001, SIP vs AIP p<0.01). The structural evaluation revealed a decrease of the Fractional Anisotropy [FA] at the Supplementary Motor Area [SMA] level in both groups of patients compared to controls (controls vs SIP p<0.05, controls vs. AIP p<0.001). At the caudate nucleus, the AIP group showed FA value decrease compared to controls (p<0.001) and SIP subjects (p<0.05). Thus, these results would contribute to a better characterization and understanding of the cortical and subcortical impairments of the postural regions in ALS patients.

A novel integrated modeling methodology for NEMS is presented. Nano scale device models include typical effects found, at this scale, in various domains. The methodology facilitates the insertion of quantum corrections to nanoscale device models when they are simulated within multi-domain environments, as is performed in the MEMS industry. This methodology includes domain-oriented approximations from ab-initio modeling. In addition, the methodology includes the selection of quantum mechanical compact models that can be integrated with basic electronic circuits or non-electronic lumped element models. Nanoelectronic device modeling integration in mixed signal systems is reported. The modeling results are compatible with standard hardware description language entities and building blocks. This methodology is based on the IEEE VHDL-AMS, which is an industry standard modeling and simulation hardware description language. The methodology must be object oriented in order to be shared with current and future nanotechnology modeling resources, which are available worldwide. In order to integrate them inside a Learning Management System (LMS), models were formulated and adapted for educational purposes. The electronic nanodevice models were translated to a standardized format for learning objects by following the Shareable Content Object Reference Model (SCORM). The SCORM format not only allows models reusability inside the framework of the LMS, but their applicability to various educational levels as well. The model of a molecular transistor was properly defined, integrated and translated using SCORM rules and reused for educational purposes at various levels. A very popular LMS platform was used to support these tasks. The LMS platform compatibility skills were applied to test the applicability and reusability of the generated learning objects. Model usability was successfully tested and measured within an undergraduate nanotechnology course in an electrical engineering program. The model was reused at the graduate level and adapted afterwards to a nanotechnology education program for school teachers. Following known Learning Management Systems, the developed methodology was successfully formulated and adapted for education.

Les systèmes industriels sont de plus en plus miniaturisés et intégrés. Ils font cohabiter sur le même substrat différentes disciplines techniques (électronique analogique et numérique, optique, mécanique, thermique, différents capteurs ...). Le cycle de conception traditionnel en V ne répond plus aux exigences industrielles et beaucoup de problèmes restent à identifier et à résoudre pour avancer dans ce domaine. Les phénomènes perturbateurs prennent de plus en plus d'importance à mesure que la taille des systèmes diminue. Leur conception doit en tenir compte dés le début de la démarche.<br /> L'évolution industrielle dans ce domaine passe par la fourniture de procédures réalistes et productives pour améliorer le cycle de conception. Le Prototypage Virtuel constitue une voie intéressante pour cela en offrant la possibilité de réduire les temps et les coûts de développement par la formalisation, la capitalisation et la réutilisation de modèles informatiques directement simulables, ainsi que par l'application d'une méthodologie rigoureuse quant à leur conception. Parmi les langages de description matériels utilisables, VHDL-AMS semble un des plus adaptés. En effet, il permet de modéliser les systèmes multidisciplinaires de manière native et offre des possibilités de modélisation à haut niveau d'abstraction. De plus, ce langage se déploie de plus en plus au sein des industries, ce qui génère un nouveau public d'utilisateurs, n'ayant pas de connaissances des HDLs, pour lesquels la nouvelle génération de simulateurs graphiques s'avèrent très utiles.<br /> Cette thèse présente tout d'abord le travail effectué dans le cadre du RMNT sur la modélisation d'un dispositif optoélectronique à haut débit, courte portée et à fortes interactions thermiques et mécaniques de la société THALES. Cette étude a ensuite permis de dégager des éléments de méthodologie qui pourraient rendre la conception de modèles et la simulation de systèmes complexes plus en phase avec un marché toujours plus exigeant.

L'expérience AMS-02 est un détecteur de physique des particules qui sera installé sur la station spatiale internationale (ISS) pour une durée d'au moins 3 ans début 2008. Les motivations physiques sont la mesure des rayons cosmiques (e-, e+, p, p-bar, gamma, He, C,...), la recherche indirecte de matière noire, la recherche d'antimatière pour Z>2 et l'étude des photons du GeV au TeV. L'expérience HEAT a mesuré le spectre de positons jusqu'à 30 GeV. Elle montre une possible distorsion autour de 8 GeV, qui peut s'interpreter comme un signal de matière noire. La mesure du spectre de positons cosmiques nécessite une séparation positons/protons de l'ordre de 10^5, obtenue par l'utilisation conjointe des sous-détecteurs d'AMS-02. Les tests en faisceaux de 2002 du calorimètre électromagnétique ont permis de déterminer son pouvoir de séparation "électrons"/protons grâce à un réseau de neurones. Cette technique, basée sur des variables discriminantes et mise au point sur les données, a été utilisée pour déterminer l'acceptance en positons du détecteur en combinant les informations des autres sous-détecteurs. On peut aussi estimer le nombre de positons d'origine conventionnelle et déterminer la capacité de détection de signaux issus de matière noire froide. Cette étude est présentée pour des signaux issus de neutralinos supersymétriques et de particules stables de Kaluza-Klein. Les flux restent naturellement trop faibles pour être détectables. Le signal peut être amplifié grâce à l'existence de surdensités locales de matière noire qui apparaissent naturellement dans les modèles de formation de galaxie. Une modélisation de ces surdensités a été mise au point et présentée.

<p>For emergency service providers, giving their service in least time shows their best performance. Emergency hospitals will be at their best if the ambulance reaches the site in Golden hour where life of injured persons can be saved. Ambulance uses the road network to reach the accident site. Today there are many GIS based systems being developed for routing of ambulance using GPS and other real-time technologies. These systems are useful and play a major role in solving the routing problem. But now roads are so congested that it difficult for the Ambulance drivers to travel and reach the accident.</p><p>In this thesis present study area is studied and problems faced by emergency service providers on road network are identified. In this thesis GIS/GPS/GSM based prototype system has been developed for routing of ambulance on road network of Hyderabad city (AMS). This prototype is designed such that it finds the accident location on the road network and locates the nearest ambulance to incident site using the real-time technologies (GPS/GSM). AMS creates the fastest route from nearest ambulance to accident site, and from there to nearest hospital. Congestion on roads during peak hours is considered, and the fastest route on both major and minor roads is created.</p><p>In this thesis AMS user interface has been developed using VBA, ArcGIS (network analyst). This Ambulance management system has been developed using software engineering model rapid prototyping model and has been evaluated by GIS users</p>

Abstract Title: To work or not to work, an essay about information and inspiration on www.ams.se. Number of pages: 39 Author: Ann Höglund Tutor: Peder Hård af Segerstad Course: Media and communication Studies D Period: Fall 2005 University: Uppsala University, Department of information science, Division of Media and Communication Purpose/Aim: To investigate the frequency of ethos, logos and pathos in the work-guides on www.ams.se, and study how they match the needs of the respondents in the essay-interviews. Method/Material: To investigate the needs and wishes for information I have made three group-interviews with university students. In order to analyse the texts and films on www.ams.se I have used tools from the modern rhetoric analysis. In the last part of my analysis I compared the results of the rhetoric analysis and the requests from the interviews to see if and how they match. Main Results: The respondents requested inspiration for their future work lives, and information that could de-dramatize the image of working. The texts on www.ams.se consist mostly of facts, while the films made a slightly more emotional contribution to the image of the occupation. The films showing relaxed and satisfied people can be seen as a way to de-dramatize the image of working-life. The people in the films offer the viewer a personal perspective on the job, and the texts present facts and information that might be used for further research. Key words: AMS, working life, information, inspiration, youths, ethos, logos, pathos.
