HelenOS VFS-FUSE connector / HelenOS VFS-FUSE connectorBouška, Zdeněk January 2014 (has links)
This master thesis deals with the implementation of a connector between FUSE file system drivers and HelenOS native VFS interface. The thesis first describes the way of finding the best solution and the potential possibilities. The low level layer solution is described as the best one. Further the thesis describes the real implementation of the connector. As the implementation of the connector was successful the thesis then describes in detail the parts of the fully functional solution in real-life HelenOS system. With this solution in place almost no changes are necessary to be done neither in FUSE nor in Helenos VFS. The connector implementation is demonstrated on a real-life FUSE file system exFAT ported to HelenOS. Powered by TCPDF (www.tcpdf.org)

HelenOS VFS-FUSE connector / HelenOS VFS-FUSE connectorBouška, Zdeněk January 2013 (has links)
This master thesis deals with the implementation of a connector between FUSE filelesystem drivers and HelenOS native VFS interface. The thesis first describes the way of finding the best solution and the potential possibilities. The low level layer solution is described as the best. Then the concern is focused on the real implementation of the connector. The implementation was successful, so the thesis describes in detail the parts of the fully functional solution in real-life HelenOS system. The solution enables almost no need of changes to be made in both FUSE and Helenos VFS. The connector implementation is demonstrated on a real-life FUSE filesystem Exfat ported to HelenOS.

Slimming virtual machines based on filesystem profile dataNickurak, Jeremy 11 1900 (has links)
Virtual machines (VMs) are useful mechanisms for better resource utilization, support for special software configurations, and the movement of packaged software across systems. Exploiting VM advantages in a production setting, however, often requires computer systems with the smallest possible disk-size footprint. Administrators and programmers who create VMs, however, may need a robust set of tools for development. This introduces an important conflict: Minimalism demands that packaged software be as small as possible, while completeness demands that nothing required is missing. We present a system called Lilliputia, which combines resource usage monitoring (through a Linux FUSE filesystem we created called StatFS), with a filtered cloning system, which copies an existing physical or virtual machine into a smaller clone. Finally, we show how Lilliputia can reduce the size of the Trellis Network-Attached-Storage (NAS) Bridge Appliance and the Chemical Shift to 3D Structure protein structure predictor to 10-30% of their original size.

Modeling of a DC fuse for protection of semiconductor devices using PSCAD/EMTDCDevarajan, Bhargavi 01 November 2010 (has links)
This thesis presents a new simulation model for DC fuses used to protect semiconductor devices using PSCAD /EMTDC. The basic construction and operation of fuses is discussed, highlighting the difference between the operations of AC and DC fuses. The melting and arcing models of the fuse are implemented separately. The modeling concept is explained in detail and the model is validated with experimental results. / text

Envolvimento do núcleo Kölliker-Fuse e do núcleo parabraquial lateral no controle cardiorrespiratório promovido pela ativação dos quimiorreceptores centrais e periféricos. / Involvement of the Kölliker-Fuse nucleus and lateral parabrachial nucleus in cardiorespiratory control elicited by central and peripheral chemoreceptors activation.Damasceno, Rosélia dos Santos 20 March 2014 (has links)
No presente trabalho, avaliamos o envolvimento da região Kölliker Fuse (KF) e núcleo parabraquial lateral (NPBL) nas respostas cardiorrespiratórias induzidas pela ativação dos quimiorreceptores centrais e periféricos em ratos não anestesiados. A injeção bilateral de muscimol (200 pmol/100 nl) no KF reduziu a ventilação basal (978 ± 100, vs. salina: 1436 ± 155 ml/kg/min). Injeção de muscimol no KF reduziu a hiperventilação (1827 ± 61, vs. salina: 3179 ± 325 ml/kg/min) e a taquicardia (380 ± 9, vs. salina: 423 ± 12 bpm), produzidos pela hipóxia (8% O2 - 10 min). Muscimol no KF reduziu a hiperventilação (1488 ± 277, vs. salina: 3539 ± 374 ml/kg/min) produzida por hipercapnia (7% CO2 - 10 min). Injeção de muscimol no NPBL promoveu um aumento de PAM (D = 119 ± 2, vs. salina: 104 ± 2 mmHg), mas não foi capaz de alterar a hiperventilação produzida por hipóxia e hipercapnia. Nossos experimentos mostram a participação da região KF, e não do NPBL, no controle do respiratório durante a ativação do quimiorreflexo central e periférico. / Here we evaluated the involvement of Kölliker-Fuse region (KF) and lateral parabrachial nucleus (LPBN) in the cardiorespiratory responses elicited by chemoreceptor activation in conscious rats. Bilateral injection of muscimol (200 pmol/100 nl) into the KF decreased resting ventilation (978 ± 100, vs. saline: 1436 ± 155 ml/kg/min). Muscimol injection into the KF reduced the increase in ventilation (1827 ± 61, vs. saline: 3179 ± 325 ml/kg/min) produced by hypoxia (8% O2 - 10 min) or hypercapnia (7% CO2 - 10 min) (1488 ± 277, vs. saline: 3539 ± 374 ml/kg/min). The injection of muscimol into the LPBN increased resting MAP (D =119 ± 2, vs. saline: 104 ± 2 mmHg). Muscimol into the LPBN did not change the increase in ventilation elicited by hypoxia or hypercapnia in unrestrained rats. The results of the present study suggest that KF region, but not LPBN, have mechanisms to control the ventilation in resting, hypoxic or hypercapnic conditions in conscious rats.

Comparação entre coordenadas geográficas-geodésicas transportadas pelo método clássico e por GPS / Comparison between geodetic coordinates calculated by a private classic method and geodetic coordinates performed through the global positioning system methodMenzori, Mauro 27 April 2001 (has links)
Este trabalho tem o objetivo de apresentar a revisão do clássico procedimento geodésico, adotado pela DSG - Diretoria do Serviço Geográfico do Exército, para o cálculo do transporte de coordenadas geográficas-geodésicas dos vértices da rede fundamental implantados no Brasil entre 1940 e 1970, antes do surgimento das técnicas de posicionamento. Neste trabalho, uma aplicação prática do método foi desenvolvida, empregando-o na solução de um problema específico da projeção cartográfica UTM, que é o transporte de coordenadas na passagem do limite entre fusos. Para isto foi escolhida uma área localizada na divisa entre os municípios de São Carlos e Ibaté no Estado de São Paulo, atravessada pelo meridiano de 48º, limite entre os fusos 22 e 23 desta projeção. Na área implantou-se duas bases geodésicas determinadas através de técnicas de observação do Sistema de Posicionamento Global, sendo uma base posicionada no fuso 22 e outra no fuso 23. Inicialmente, entre estas bases, desenvolveu-se uma poligonal de adensamento constituída de 7 vértices, que teve seus lados e ângulos observados com estação total, possibilitando o cálculo de suas coordenadas geográficas-geodésicas pelo método clássico em pauta. Numa segunda etapa do trabalho, foram observados com receptores GPS de uma freqüência, os 8 vetores relativos aos lados da poligonal de adensamento, empregando o método diferencial estático. Cada um dos 7 vértices da poligonal teve suas coordenadas geográficas-geodésicas determinadas por pós-processamento, permitindo a comparação entre os resultados obtidos nos dois procedimentos utilizados. Na etapa final, comparando-se os resultados obtidos pelos dois diferentes métodos, pode-se verificar que apesar da técnica em desuso empregada pelo método clássico, ela conduziu os cálculos com o rigor e aproximação adequados, produzindo coordenadas de valores significativamente próximos aos valores determinados pela mais avançada tecnologia empregada nos dias atuais que é a tecnologia GPS. / The main objective of this job, is a review about the classic mathematical proceedings applied to the polygonals which cross the fuses limits of the Universal Traverse of Mercator projection. In this cases, the poligonal begin to be measured in a baseline located in a private fuse and finishs in a different baseline located in the next fuse, where the coordinates are refered to a different origin. In this conditions, the rules of UTM projection defines a range of 30 minutes over the fuse limit, where the coordinates can be calculated either in the first or int the second fuse. However, there are specials situations where the polygonals has a baseline for ending so far over this 30 minutes range. In this cases, the mathematical proceeding is to calculate the transportation of geodetic-coordinates in the ellipsoid obtaining the latitude \'fi\' and the longitude \'lâmbda\' for all points in the polygonal and after, making the transformation, observing in which fuse each point is positioned, to get the UTM planned coordinates. The Global Positioning System will be used in this job to do the control over the classic measurements and over the classic calculated coordinates, offering conditions to the comparison between them.
