Full textThe Explanation Hypothesis is a psychological hypothesis about how people attribute moral responsibility. The hypothesis makes general claims about everyday thinking of moral responsibility and is also said to have important consequences for related philosophical issues. Since arguments in favor of the hypothesis are largely based on a number of intuitive cases, there is need to investigate whether it is supported by empirical evidence. In this study, the hypothesis was tested by means of quantitative experimental methods. The data were collected by conducting online surveys in which participants were introduced to a number of different scenarios. For each scenario, questions about moral responsibility were asked. Results provide general support for the Explanation Hypothesis and there are therefore more reasons to take its proposed consequences seriously.

Full textthe effect of length to diameter ratio of the probe on the deformation modulus is minor where as it causes overestimations of undrained shear strength. Pore pressure dissipation in low permeability soils around the pressuremeter was studied using numerical simulations. These analyses suggest that for permeabilities lower that 10-10 m/sec there is no pore pressure dissipation around the pressuremeter probe. It was determined that the inverse analysis yielded successful results for the determination of shear strength parameters of intermediate geomaterials.

The LIGO (Laser Interferometer Gravitational-wave Observatory) project is designed to detect gravitational waves using precision interferometry. The detection from astrophysical sources has the potential to test Einstein's Theory of General Relativity, and additionally open a new window into the universe and its origin. The Initial LIGO detectors are currently operating at a strain sensitivity of 10-21 Hz, or equivalently 1018 m/ [square root of] Hz, at 100 Hz. In order to attain improved sensitivity required for guaranteed detection of astrophysical sources, e.g. coalescing neutron star binaries and black holes, pulsars, and supernovae collapses, improvements of the strain sensitivity must be achieved. Next generation detectors such as Advanced LIGO are under development, which aims to improve the sensitivity by more than a factor of 10 at all frequencies, compared to initial LIGO. This improvement in sensitivity will be achieved in part by improved seismic isolation one component of which is an active vibration isolation platform. Currently, research and development is being conducted at MIT on a prototype of this vibration isolation system. The work described in this thesis focuses on the Internal Seismic Isolation (ISI) system under development for Advanced LIGO.
(cont.) This system consists of a three-stage in-vacuum seismic isolation system which is supported by an external hydraulic actuation stage known as the Hydraulic External Pre-Isolation (HEPI) stages of the active vibration control system. HEPI uses forces generated by hydraulic pressure to cancel low frequency seismic noise, primarily due to forces from ground vibration. The ISI is an actively controlled platform, in which each stage is supported by three maraging steel blade springs. The vibration is sensed in six degrees of freedom and reduced by applying forces through a control feedback loop. In order for the feedback loop to function properly, it is important to know and be able to predict the position of the ISI stages to within a few thousandths of an inch. Since the load being applied to the spring blades is known, the compliance of each spring along with various shim thicknesses will determine the final position of the stages. Although compliance is a material and geometric property, and should remain constant from spring to spring, due to imperfections of the fabrication process and variation in the material properties, small variations in the long and short spring compliance value were detected using a Spring Tester.
(cont.) The blades were designed based on their resonant frequencies and the load which they would be supporting - more specifically, their geometry (length, width, and thickness) were defined such that the load each supported brought them to a 1/3 of their failure stress. For my undergraduate thesis, I determined the compliance of multiple long and short springs was determined using a specially designed apparatus - the "Spring Tester." Ideally, three blade springs of identical compliance should be used to eliminate system imbalance, but to variation during fabrication may be difficult to achieve Using the Spring Tester the mean values for each set of long and short spring linear compliance data were found to be 0.729 +.008 mils/lb and 0.670 ±.027 mils/lb, respectively, while the means for the long and short angular compliance data were 0.078 + .001 mrad/lb and 0.089 ±.003 mrad/lb, respectively.

Aplicações para celular estão se tornando cada vez mais complexas, bem como testá-las. Teste de interfaces gráficas (GUI) é uma tendência atual e se faz, em geral, através da simulação de interações do usuário. Várias técnicas são propostas, no qual, eficiência (custo de execução) e eficácia (possibilidade de encontrar bugs) são os aspectosmais cruciais desejados pela industria. No entanto, avaliações mais sistemáticas são necessárias para identificar quais técnicas melhoram a eficiência e eficácia de tais aplicações. Esta tese apresenta uma avaliação experimental de duas técnicas de testes de GUI, denominadas de DH e BxT, que são usadas para testar aplicações de celulares com um histórico de erros reais. Estas técnicas são executadas por um longo período de tempo (timeout de 40h, por exemplo) tentando identificar as situações críticas que levam o sistema a uma situação inesperada, onde o sistema pode não continuar sua execução normal. Essa situação é chamada de estado de crash. A técnicaDHjá existia e é utilizadapela industriade software, propomos outra chamada de BxT. Em uma avaliação preliminar, comparamos eficácia e eficiência entre DH e BxT através de uma análise descritiva. Demonstramos que uma exploração sistemática, realizada pela BxT, é uma abordagem mais interessante para detectar falhas em aplicativos de celulares. Com base nos resultados preliminares, planejamos e executamos um experimento controlado para obter evidência estatística sobre sua eficiência e eficácia. Como ambas as técnicas são limitadas por um timeout de 40h, o experimento controlado apresenta resultados parciais e, portanto, realizamos uma investigação mais aprofundada através da análise de sobrevivência. Tal análise permite encontrar a probabilidade de crash de uma aplicação usando tanto DH quanto BxT. Como experimentos controlados são onerosos, propomos uma estratégia baseada em experimentos computacionais utilizando a linguagem PRISM e seu verificador de modelos para poder comparar técnicas de teste de GUI, em geral, e DH e BxT em particular. No entanto, os resultados para DH e BxT tem uma limitação: a precisão do modelo não é estatisticamente comprovada. Assim, propomos uma estratégia que consiste em utilizar os resultados anteriores da análise de sobrevivência para calibrar nossos modelos. Finalmente, utilizamos esta estratégia, já com os modelos calibrados, para avaliar uma nova técnica de teste de GUI chamada Hybrid-BxT (ou simplesmente H-BxT), que é uma combinação de DH e BxT

Full textF¨or att m¨ojligg¨ora anv¨andning av kompositpropellrar av kolfiberf¨orst¨arkt polymer (CFRP) f¨or handelsfartyg, m˚aste problemet med kavitation l¨osas. Matrisen i FRP ¨ar i regel v¨aldigt spr¨od och mer k¨anslig f¨or kavitation-serosion ¨an de mera konventionella metallpropellerbladen. Tillverkningsf¨oretaget Nakashima Propeller Co. vill l¨osa detta problem genom att f¨asta en metallplatta fastlimmad i h¨ogriskomr˚adena p˚a bladet. F¨orbandet av FRP och metall ¨ar ett klassiskt problem vid tillverkning av hybridkomponenter, och ¨annu sv˚arare n¨ar det ¨ar utsatt f¨or utmattningsbelastningar, i en marin milj¨o. D˚a det ¨ar en relativt tunn metallplatta ¨ar det sv˚art att best¨amma sprickmots˚andet fr˚an energidissipationshastigheten G och ett nytt tillv¨agag˚angss¨att ¨ar n¨odv¨andigt.Denna rapport fokuserar p˚a beskriver problemet och etablerar en experimentell metod f¨or att genomf¨ora inledande unders¨okningar av robusthet en limbindning f¨or denna applikation. Fyra olika lim testades i kvasi-statiskt lastning av mod I med konstant cross head-hastighet: Denatite 2204, samh¨ardning, Newport 102 och Plexus AO420. Alla lim var epoxibaserade f¨orutom Plexus. Det samh¨ardade systemet anv¨ande samma matris som vid tillverkningen av FRP i de andra provbitarna: Epolam 5015. I st¨allet f¨or att ber¨akna energidissipationshastigheten j¨amf¨ordes vinklarna vid sprickspetsen mellan de olika limsystemen. Dessa m¨atningar var bara internt j¨amf¨orbaa inom testserien. Baserat p˚a resultaten fr˚an den kvasi-statiska belastningen togs enbart Denatite och Plexus vidare till en mindre serie utmattningsprover. De tv˚a andra ans˚ags alltf¨or svaga f¨or att vara av intresse.F¨ors¨oken visade att metakrylatbaserade Plexus AO420 hade en betydligt h¨ogre styrka, i kvasi-statisk belast-ning hade det den h¨ogsta uppm¨atta lasten, n¨astan tio g˚anger s˚a h¨og som Denatite 2204. Det gick inte attd ra npgra direkta slutsatser fr˚an utmattningstestet, men inget drastiskt eller ov¨antat beteende registrerades. Det noterades under processen (inte f¨orv˚anande) att tillverkningsprocessen och skickligheten hos arbetaren ¨ar myckket viktig och p˚averkar f¨orbandsstyrkan i h¨og grad, ibland ¨annu mer ¨an materialegenskaper och de ytbehandlingar som till¨ampas.Slutsatsen att den experimentella metoden, inklusive m¨atningar av sprickspetsvinkeln kan beskrivas som en enkel men effektiv metod f¨or att j¨amf¨ora och dra slutsatser om vidh¨aftningsstyrkan och allm¨anna egenskaper hos de olika limtyperna kan dras. Den andra serien av utmattningsprovning kan utf¨oras f¨or att se allm¨ant utmattningsbeteendet f¨or limmen, men d˚a det faktiska lastfallet p˚a propellern ¨ar ok¨ant kan det vara sv˚art att direkt relatera utmattningsbeteende i testet till den verkliga v¨arlden. B˚ada provserierna kan anv¨andas f¨or att best¨amma allm¨anna beteenden, men p˚a grund av komplexiteten av geometri, deformationstillst˚and och belastningar p˚a den verkliga propellern f¨oresl˚as det att utf¨ora slutliga tester p˚a en riktig propeller, snarare ¨an att f¨ors¨oka dra stora slutsatser fr˚an isolerade experiment.
