Повний текст джерелаCell-cell or cell-matrix interactions have crucial roles in the maintenance of the physical cohesion of any tissue. In addition, growing body of evidence indicates that these two adhesion systems do not act independently, but rather are functionally interconnected by a permanent crosstalk. This dialog usually operates via common molecules that trigger convergent signaling as well as by actomyosin network which, by providing physical link, contributes to establishment of intracellular force counterbalancing tension applied by extracellular surrounding. Blood vessels endothelium is a particular tissue in term of mechanical conditions. Apart from intracellular compression, endothelial lining needs to resist hemodynamic forces as well as rigidity of the basal membrane - two mechanical inputs acting from opposite sides of the endothelial layer. Cerebral Cavernous Malformation (CCM) is a sporadically acquired or inherited disease of venous capillaries within neuro-vascular unit characterized by defects in all aspects of local microenvironment. Loss of intra-endothelial junctions and mural cell coverage, aberrant organization of basal lamina as well as stagnant blood flow are features of CCM lesions. Thereby, CCM became for us an interesting model to study mechanotrasduction process and in this context, the cross-talk between integrin and cadherin mediated adhesion structures. Indeed, CCM proteins are well recognized players involved in a control of VE-cadherin mediated intracellular junctions. In addition, CCM1 was found to interact with ICAP-1, a negative regulator of β1 integrin, raising the possibility that this complex most likely acts as molecular node regulating β1 integrin/ VE-cadherin convergent signaling pathways.Studies performed during this thesis have demonstrated that CCM complex coordinates cadherin- and integrin-mediated tensional homeostasis by repressing β1 integrin activation and maintaining a balance of activity between the two isoforms of RhoA-associated kinases ROCK1 and ROCK2. We have found that β1 integrin sustained over-activation upon CCM proteins loss contributes to increased ECs sensitivity to mechanical cues, such as ECM physical reorganization or hemodynamic force that in turn activates ROCK1-dependent contractility. This establishes a positive feedback mechanical loop that breaks tensional homeostasis and switches on the malignant phenotype

Os métodos de aquisição de imagem utilizados em medicina nuclear e na radiobiologia são valiosos na determinação da anatomia da glândula tireóide na busca de anormalidades associadas ao comportamento das células foliculares. A simulação baseada no método Monte Carlo (MC) também tem sido muito utilizada na solução de problemas relacionados à detecção da radiação visando o mapeamento de imagens médicas desde a evolução da capacidade de processamento dos computadores pessoais (PC). Este trabalho apresenta um estudo inovador para encontrar o tipo adequado de matriz cintiladora, que uma vez acoplada a um dispositivo CCD (Charge Coupled Device) através de uma placa de fibra ótica, pode ser aplicado no mapeamento de imagens de folículos da glândula tireóide. A metodologia utiliza a técnica de imageamento por emissão gama e a simulação MC, visando o desenvolvimento de um sistema capaz de obter uma imagem com resolução espacial de 10 m e boa eficiência do detector. A simulação do conjunto fonte-detector foi realizada por meio do programa MCNP4B (Monte Carlo para nêutron próton transporte) para diferentes energias, materiais detectores e geometrias, incluindo tamanho de “pixel” e tipos de materiais refletores. Os resultados alcançados mostram que utilizando o MCNP4B é possível estudar e avaliar parâmetros úteis relacionados aos sistemas utilizados em medicina nuclear, especificamente em radiobiologia aplicada a estudos da fisiologia endócrina no mapeamento de imagens de folículos tireoideanos.
The image acquisition methods applied to nuclear medicine and radiobiology are a valuable research study for determination of thyroid anatomy to seek disorders associated to follicular cells. The Monte Carlo (MC) simulation has also been used in problems related to radiation detection in order to map medical images since the improvement of data processing compatible with personnel computers (PC). This work presents an innovative study to find out the adequate scintillation inorganic detector array that could be coupled to a specific light photo sensor, a charge coupled device (CCD) through a fiber optic plate in order to map the follicles of thyroid gland. The goal is to choose the type of detector that fits the application suggested here with spatial resolution of 10 m and good detector efficiency. The methodology results are useful to map a follicle image using gamma radiation emission. A source - detector simulation is performed by using a MCNP4B (Monte Carlo for Neutron Photon transport) general code considering different source energies, detector materials and geometries including pixel sizes and reflector types. The results demonstrate that by using MCNP4B code is possible to searching for useful parameters related to the systems used in nuclear medicine, specifically in radiobiology applied to endocrine physiology studies to acquiring thyroid follicles images.

Повний текст джерелаExamensarbetet utfördes på Zetterbergs Industri AB i Östervåla. Arbetet är ett 15 högskolepoängsarbete/student dvs cirka 20 veckors arbete totalt då arbetet är utfört av två studenter. Zetterbergs konstruerardesignar, tillverkar och monterar lastbilspåbyggnader och har deras tyngdpunkt på anläggningsfordon i Norden. Zetterbergs släppte nyligen ett nytt lastväxlardumperflak kallat ZD4-LV. Detta flak marknadsförs som en lågviktare med snygg design. Flaket är byggt enligt svensk standard och Zetterbergs vill ta fram en variant på flaket som istället följer den tyska standardentysk standard som används i Europa. Arbetet tog sin början i en granskning av de två olika standarderna SS 3021 och DIN 30722. Även den svenska varianten av ZD4-LV gicks igenom för att få en djupare förståelse i hur flaket var uppbyggt. Då det önskades att korgen från den befintliga lastväxlardumpern skulle används för den europeiska varianten så gjordes en granskning även i hur den befintliga lastväxlardumpern tillverkas. Femstegsmetoden användes för att generera olika koncept som sedan utvärderas och viktades i en Pugh matris. De valda koncepten från Pugh matriserna vidareutvecklades vidare som senare senare som mynnade ut i ett antal slutgiltiga konstruktioner. Resultatet blev en färdig CAD-modell med tillhörande tillverkningsritningar av en komplett lastväxlardumper som följer den europeiska tyska standarden DIN 30722. Ritningar och CAD-modeller har gjorts på samtliga delar och sammanställningar förutom på befintliga delar då dessa redan finns. Arbetet anses lyckat då alla uppsatta mål har blivit uppfyllda samt att en del extra önskemål har kunnat tillgodoses.

Este trabalho apresenta um novo conceito para a aceleração do método TLM bidimensional (TLM-2D). A técnica baseia-se na utilização de saltos controlados no passo de tempo em conjunto com a redução de ordem de modelo, obtendo assim um processamento mais rápido. Estes saltos são numericamente estáveis e podem resultar em considerável redução na utilização do processador. Para tornar o método mais eficiente emprega-se a redução de ordem de modelo por meio da decomposição de Schur ou via decomposição em autovalores, utilizando a transformada Z. Além disso, apresenta-se aplicações da envoltória complexa na modelagem numérica utilizando o método TLM-JSN (Transmission Line Matrix - John´s Super Node) e adaptação da técnica de diakópticas na modelagem TLMJSN. A metodologia é validada através de comparações com o método TLM convencional, mediante o cálculo de diversas estruturas. _________________________________________________________________________________ ABSTRACT
This work presents a new concept for the acceleration of the TLM method. The technique is based on the use of controlled timestep jumps together with model order reduction. This results in faster processing. These jumps are numerically stable and can result in considerable computational savings. The method can be optimized through model order reduction using Schur decomposition or through Z-transform eigenvalue decomposition. In addittion, this work presents the application of the complex envelope in TLM-JSN (Transmission-Line Matrix - John’s Super Node) together with the appllication of diakoptics techniques. The methodology is validated through comparisons with the method TLM conventional, by the calculation of several structures.

Повний текст джерелаThe aim of this project has been to improve the existing noise diffuser used currently today in the oil-separatingmachines developed by 3nine AB. By reducing noise levels, increasing the air flow, increasing the “ease of assembly” and making it more cost effective. The thesis follows the product development process described in the book “Product Development - Construction and Design” by Karl T. Ulrich and Steven D. Eppinger. The work was adapted for a 10-week timeframe and divided into four phases. Phase 1 - Pre-Study, Phase 2 – Information gathering, Phase 3 - Implementation and Phase 4 - Reporting. The solution used today consists of five folded pieces of stretch metal that have been sewn together with steel wire, the noise diffuser takes a long time to assemble and to fit into the machine. The five folded pieces of stretch metal have sharp edges after cutting, which further complicates the assembly. The production cost for each diffuser is 100 kronor. For the present solution, the measurement values taken at 3nine AB's workshop were set as reference values, assembly time - 333 [s], noise level - 68 [dB], airflow - 319 [m³ / h] and DFA-index (measurement value for ease of assembly) - 5.4%. DFA-index when 100% is seen as the optimal ease of assembly and a higher DFA-index leads to reduced costs. As air flows through the machine, this affects the measured values and possible design of new prototypes, but fluid mechanics is one knowledge we lacked and therefor analysis of this was not possible and delimited. Through Idea Development Processes such as Brainstorming, 6-3-5 Brainwriting, Morphological Matrix, Pugh matrix, Concept Sketches, Virtual Concepts (3D-CAD) and Rapid prototyping (3D-prototype printing), five prototypes were produced, then tested for assembly time, noise level, airflow and DFA -index. These tests resulted in a prototype that featured improved results compared to the reference values of the existing noise diffuser. Measurement values for prototype "45° wall" where assembly time - 16 [s], noise level - 65 [dB], airflow - 342 [m³ / h] and DFA index - 93%. Risk-analysis and FEA was carried out on the same prototype to identify weaknesses in the design. The solutions to these weaknesses are recommended in the form of small design changes such as rounded sharp corners. These measured values state that the solution developed is better than today's solution and is recommended to be implemented and further developed by the company.

In this study, a novel positioning model of double-CCD cameras calibration system with Alternate-Eight-Matrix (AEM) Look-Up-Table (LUT) is proposed. Two CCD cameras are fixed on both side of a large scale screen to redeem the Field Of View (FOV) problem. The first to the forth AEMLUT are used to compute the corresponding position of intermediate block on the screen captured by right side camera. In these AEMLUT for right side camera, the coordinate mapping data of the target in a specific space are stored in two matrixes and the gray level threshold values in different position are stored in the others. Similarly, the fifth to the eighth AEMLUT are used to compute the corresponding position of intermediate block on the screen captured by left side camera. Experimental results show that the problems of dead angle and non-uniform light field are solved. Also, the rapid and precision positioning result can be obtained by the proposed method.

This thesis analysis the performance of an equalization/diversity-combiner operating in mobile radio environment with quadrature amplitude modulation (QAM) transmission, frequency-selective Rayleigh fading, and co-channel interference (CCI). The finite-length MMSE linear equalization/diversity-combiner has been shown to be an effective receiver structure for eliminating intersymbol interference (ISI) and cyclostationary CCI. This receiver structure with finite-length equalization uses the linear scheme and the decision feedback (DFE) scheme according to the minimum mean-square-error (MMSE) criterion. The simulation reveals that the symbol-spaced DFE, unlike operating in AWGN channel, cannot eliminate cyclostationary CCI efficiently and is even worse than symbol-spaced linear equalizer case. Since the accurate error probability estimation is time consuming, we use the Gaussian Quadrature Rule (GQR) method which is fast and accurate in evaluating average error probability.
