For the proper function of the Fluorescence olographic microscope, it is necessary to adjust all the optical components of the microscope. Furthermore, the precise adjustment is the very critical condition for proper imaging of the Coherence-controlled holographic microscope. Therefore, it is necessary to create a sight collimator for these microscopes for their adjustment. The fluorescence holographic microscope is based on an interference and holographic principles, whose history is mentioned in the theoretical part of the thesis. The existing state of the art of laser sight collimators and their use in practice is also mentioned. The optical and mechanical design of the laser sight collimator and its realization are described in the next part of the thesis. The software for detecting the black sight cross was created for the use of the laser sight collimator in practice. The software is necessary to evaluate the correctness of the alignment of the adjusted microscope. The descriptions of the adjustment procedures for the laser sight collimator and for the Fluorescence holographic microscope are mentioned in the last part of the thesis. These procedures are necessary for proper manipulation and use with the proposed laser sight collimator.

This thesis deals with testing of astronomical measurement system MAAS-1, which was developed at the Institute of Geodesy, Faculty of Civil Engineering, Brno University of Technology. Several reference measurements were done on the terrace of B building Faculty of Civil Engineering during this testing. The data obtained were processed into astronomical geographic coordinates and . These coordinates, as well as atmospheric conditions and calibration measurements, are basis for evaluation. In this test I try to detect the influence of the CCD sensor mounting of the accuracy on the final data and to assess if the construction needs to be modified.

Indoor positioning is desired in many areas for various reasons, such as positioning products in industrial environments, hospital equipment or firefighters inside a building on fire. One even tougher situation where indoor positioning can be useful is locating a specific object on a shelf in a commercial setting. This thesis aims to investigate and design different network deployment strategies in an indoor environment in order to achieve both high position estimation accuracy and availability. The investigation considers the two positioning techniques downlink time difference of arrival, DL-TDOA, and round trip time, RTT. Simulations of several deployments are performed in two standard scenarios which mimic an indoor open office and an indoor factory, respectively. Factors having an impact on the positioning accuracy and availability are found to be deployment geometry, number of base stations, line-of-sight conditions and interference, with the most important being deployment geometry. Two deployment strategies are designed with the goal of optimising the deployment geometry. In order to achieve both high positioning accuracy and availability in a simple, sparsely cluttered environment, the strategy is to deploy the base stations evenly around the edges of the deployment area. In a more problematic, densely cluttered environment the approach somewhat differs. The proposed strategy is now to identify and strategically place some base stations in the most cluttered areas but still place a majority of the base stations around the edges of the deployment area. A robust positioning algorithm is able to handle interference well and to decrease its impact on the positioning accuracy. The cost, in terms of frequency resources, of using more orthogonal signals may not be worth the small improvement in accuracy and availability.

I tid och otid har elgitarrister fått dras med stigmat att vara bristfälliga notläsare. Rimligtvis borde det gå att lösa med lite övning, men hur ska en strukturera upp sådan övning och ger det några resultat? Deras motparter i den klassiska genren åtnjuter inte samma stämpel, tack vare dess långa tradition av notläsning. Kan svaret ligga hos den klassiska gitarrens läroresurser som bara behöver översättas till elgitarr för att notläsningen ska ta fart? I denna självstudie utforskar jag min egen övning på avistaläsning för både el- och klassisk gitarr med hjälp av en videodagbok, analyserad ur ett multimodalt designteoretiskt perspektiv. / Time and again, electric guitarists have had to live with the stigma of being deficient note readers. Presumedly, this should be solvable with a little practice, but how should one structure such practice and does it produce results? Their counterparts in the classic genre do not inherit the same label, thanks to their long tradition of reading sheet music. Could the answer lie with the classical guitar's teaching methods that need only to be translated into electric guitar for the sheet music reading to take off? In this self-study, I explore my own exercise in sight reading for both electric and classical guitars with the help of a video diary, analyzed from a multimodal perspective.

Fog of War is a term for uncertainty in situational awareness. Fog of War is an essential part of a wargame which causes the participating units’ perception of the environment to be distorted and altered. Introducing a certain amount of uncertainty helps to better mimic the situation on the battlefield. Fog of War comes in multiple forms and levels, whereas the visual detection level is of primary interest for this thesis. Two forms of visual detection have been implemented to simulate a simple and advanced form of Fog of War. The simple level is based solely on the distance between two units, while the advanced level determines whether two units possess a clear line of sight between them, to decisively add realism to a played scenario. The two models were created based on the Entity Component System software architecture, and the maps used for the wargame were based on data from ArcGIS. Extensive testing of the two models, for different types of terrains, show good performance and computational efficiency, however with the expected caveat that flat landscape requires significantly more processing power and memory capacity than a hilly terrain. / Krigsdimma är en term för osäkerhet inom situationsmedvetenhet. Krigsdimma är en väsentlig del av ett krigsspel och medför att deltagande förbands uppfattning av miljön förvrängs och förändras samt att ett visst mått av osäkerhet introduceras för att bättre efterlikna situationen på slagfältet. Krigsdimma kommer i flera former och flera nivåer, där visuell detektering är av primärt intresse för denna avhandling. Två former av visuell detektering har implementerats för att simulera en enkel och en avancerad form av krigsdimma. Den enkla nivån bygger enbart på avståndet mellan två förband medan den avancerade nivån kan avgöra om två enheter i verkligheten har en fri siktlinje mellan sig, något som på ett avgörande sätt kan tillföra realism till ett spelat scenario. De två realiseringarna skapades baserat på en Entity Component System mjukvaruarkitektur, och kartorna som användes för krigsspelet baserade sig på data från ArcGIS. Omfattande tester av de två modellerna, för olika terrängtyper, visar på god funktion och beräkningseffektivitet, dock kräver flackt landskap betydligt mer processorkraft och minneskapacitet än kuperad terräng.

This study introduces a multi-objective optimization framework for the re-dimensioning of the cross-section elements of rural horizontal curves with limited sight distance. The optimization aims at minimizing both the risk of collision associated with the limited sight distance and the expected collision frequency corresponding to the cross-section elements’ dimensions. The risk component was assessed using an index known as (Pnc), which is developed based on the reliability theory. The change in collision frequency corresponding to the change of the cross-section elements was extracted from the literature. The risk and the safety components were then combined into one measure (CMFcombined) to develop a direct measure of the safety impacts of the optimization. The proposed framework was applied to five restricted curves in British Columbia, Canada, considering various scenarios. The results showed a considerable reduction in the Pnc value (ranging from 12% to 73%) and the expected collision frequency (ranging from 10% to 31%) after optimization. The estimated combined reduction in collision frequency (CMFcombined) was estimated to vary between 48% and 76%. The results showed that the optimization of cross-section elements can improve the safety of horizontal curves significantly. The framework presented in this study would support transportation engineers in selecting optimal dimensions of cross-section elements of restricted horizontal curves, understanding the safety consequences of selecting a specific cross-section configuration, and assessing the economic viability of different design options. / Thesis / Master of Applied Science (MASc)

Aluminium har flera fördelar inom konstruktion och produktframtagning. Aimpoint AB har resonerat för kostnad samt viktreducering i sikteshuset Micro T-2. Syftet med rapporten var att undersöka möjligheterna att implementera polymera material som tillfredsställer framlagd kravspecifikation för Aimpoint AB. Målet med arbetet var att identifiera lämpligt material i form av polymer, med lämplig tillverkningsmetod som kan appliceras för sikteshuset utan att påverka de mekaniska egenskaperna negativt.  Lämpliga material som identifierades under litteraturstudien i arbetet var termoplasterna polyfenylensulfid (PPS) och polyetereterketon (PEEK) med implementerat kolfiber. Valet av polymerbaserade material utgjorde ett mindre omfång av lämpliga tillverkningsmetoder, som med hjälp av leverantörer och kostnadskalkylscenarier i Excel jämfördes.  Med hjälp av tredimensionella verktyg utfördes FEM-analyser i ABAQUS CAE® av det exemplifierade sikteshuset. Baserat på simuleringarna i ABAQUS CAE®, presenterar arbetet en jämförelse mellan befintligt sikteshus av Al6082-T6 och sikteshus av polymera material med implementerad förstärkning för modellen Micro T-2. Simuleringarna konstaterade deformation vid det dynamiska explicita fallet mot en konstruerad laminatskiva enligt standarden MIL-STD-810G.  För att bekräfta material och tillverkningsmetod krävs vidare undersökning. Detta för att med säkerhet besvara arbetets frågeställningar då FEM - analyser är en approximativ lösning. / SvenskaAluminum has several advantages in construction and product development. Aimpoint AB requires to reduce both the costs and the weight of their aluminum reflex sight of model Micro T-2.   The aim with the report was to investigate the possibility to implement polymeric materials as a substitute to aluminum that fulfills the requirements specification set by the manufacturer Aimpoint AB.   In addition to that, the aim was also to find suitable polymeric materials with an alternative production technique that is applicable for the reflex sight without compromising the mechanical integrity.  Suitable materials identified during the literature part of this report were two types of thermoplastic materials, polyphenylene sulfide (PPS) and polyetheretherketone (PEEK), both with addition of carbon fiber. The selection process of the polymeric materials was based on several factors and together with contractors, different cost estimation scenarios were compared in Excel. By help from three dimensional tools, FEM-analysis of the sight were performed in ABAQUS CAE®. Based on the results from the simulations performed in ABAQUS CAE®, the report presents a comparison between the original aluminum sight with the two types of carbon fiber reinforced thermoplastic sights. During the dynamic explicit case the simulation was performed as a drop test against a laminate board according to standard MIL-STD-810G. The results of the simulation presented a deformation of the tested sight. To confirm the material and manufacturing method, further investigation is required. This is necessary to address the questions posed in the current project since the FEM - analysis is an approximate solution. / <p>2023-06-28</p>

Språket är den viktigaste faktorn för integration och nyligen har kraven på kunskaper i svenska skärpts. För att fungera fullt ut i det svenska samhället krävs en läsförmåga i nivå med årskurs 6, men en tidigare undersökning visar att majoriteten av vuxna invandrare efter avslutad SFI-utbildning endast har en läsförmåga i nivå med årskurs 3-5. En läsintervention med single-subject design har därför genomförts med tre elever på kurs C på SFI. Läsinterventionen har genomförts med Wendick-modellens läslistor tre gånger i veckan under sju veckor, totalt 20 lektioner. Resultaten visade en ökning på Avkodning Ord för en av eleverna och en ökning på Avkodning Nonord för alla tre eleverna. Dessa resultat visar att Wendick-modellens läslistor är en fungerande metod i en-till-en-situationer då elevernas avkodning på nonord har förbättrats av interventionen. Studiens resultat visar även vikten av tidiga insatser för att ge elever med bristande läs- och skrivfärdigheter rätt hjälp och stöd från studiestart för att de snabbare ska kunna integreras i samhället.
