This thesis attempts to answer the question "Can we devise a language for interpretation of behavioural simulation of engineered systems (of arbitrary complexity) in terms of the systems’ purpose?" It does so by presenting a language that represents a device’s function as achieving some purpose if the device is in a state that is intended to trigger the function and the function’s expected effect is present. While most work in the qualitative and model-based reasoning community has been concerned with simulation, this language is presented as a basis for interpret- ing the results of the simulation of a system, enabling these results to be expressed in terms of the system’s purpose. This, in turn, enables the automatic production of draft design analysis reports using model based analysis of the subject system. The increasing behavioural complexity of modern systems (resulting from the increasing use of microprocessors and software) has led to a need to interpret the results of simulation in cases beyond the capabilities of earlier functional mod- elling languages. The present work is concerned with such cases and presents a functional modelling language that enables these complex systems to be analysed. Specifically, the language presented herein allows functional description and interpretation of the following. • Cases where it is desired to distinguish between partial and complete failure of a function. • Systems whose functionality depends on achieving a sequence of intermittent effects. • Cases where a function being achieved in an untimely manner (typically late) needs to be distinguished from a function failing completely. • Systems with functions (such as warning functions) that depend upon the state of some other system function. This offers significant increases both in the range of systems and of design analysis tasks for which the language can be used, compared to earlier work.

Studies in the past few years have found that California has the highest recidivism rate in the nation. Until just a few decades ago, many did not believe that the rate of recidivism could be decreased for Robert Martinson’s 1974 study stated that “nothing worked” when trying to rehabilitate criminals. However, a renewed interest has proven that criminals can be rehabilitated. Thus, the California Department of Corrections and Rehabilitation (CDCR), as well as various independent researchers have begun to study the effects of programming on inmates. This thesis evaluates various California in-prison and parole programs in order to determine if recidivism can be reduced, and if it can, how? Researching a CDCR study, as well as other independent studies, it can be concluded that California can reduce its recidivism rates and that there are various principles that will help to accomplish this. However, while various evaluated programs proved successful one cannot accurately determine how successful the programs are at reducing recidivism due to the problem posed by the selection effect. Therefore, while recidivism can be reduced and it appears that specific programs and principles will prove valuable in accomplishing this goal, more research should be conducted in order to determine whether the programs are successful or whether the success is due to the inmates enrolled.

ABSTRACT Almost people hurt or die because of heavy smoke when the building fires. Smoke Management is to keep the smoke in the limited zone or to change its direction and to keep the ways which the people escape bright. It is convenient for fireman to save them and to keep their life and to reduce the money loss. In the developed country of the world, smoke management design is one of the most important factors to affect egress system of the building. Effective smoke management design is to avoid the smoke diffusing or descending and to make the people have enough time to escape. The combination of smoke management and egress system using performance-based fire safety design should be developed safely and economically. In Taiwan,we haven¡¦t the proper law of smoke management and egress system about the atria of the large space. So we must progress the computer simulation about smoke management and egress system and then use full-scale experiment to perform. The major terms of the content are: 1.the optimal distribution zone analysis of smoke management of the building. 2.to design and to analyze smoke management of the atria. 3.the combination of design analysis of smoke management and egress system. 4.full-scale experimental investigation. We hope that the performance-based fire safety design method about smoke management and egress system of the large shopping mall could be the excellent model and enchance the safety of the building in Taiwan.

<p>Policies of tenure mix have been widely adopted in many industrialized nations and are often justified as a means of attenuating the detrimental effects of concentrated urban poverty. In this thesis, the case of Toronto’s Regent Park community is examined. It is the first large-scale mixed tenure redevelopment of a publicly subsidized housing community in Canada. Using a series of 24 semi-structured qualitative interviews with residents from both tenures, I examine their experience of living in a mixed tenure community and gauge their support for policies of tenure mix more generally. Broader determinants of residential satisfaction in the neighbourhood are also examined. The redeveloped Regent Park is considered to be a relatively safe, convivial, well-serviced, well-situated, and aesthetically pleasing neighbourhood by individuals from both tenures. Further, participants from both tenures expressed support for the ostensible goals of the redevelopment. Resident experiences diverge significantly by tenure with regard to their satisfaction with the management and maintenance of their buildings. Particularly, individuals in the public buildings expressed considerable displeasure with how their buildings were managed and experienced serious physical difficulties that, in some cases, had adverse effects on their health and wellbeing. I find that tenure mix enjoys considerable support from residents of both tenures, with especially strong support evinced by a subset of condominium residents. To assess the efficacy of tenure mix, I employ a conceptual framework provided by Joseph (2006) and find some evidence that the redevelopment has strengthened the social capital of publicly-subsidized tenants. For most residents, more proximal concerns take precedence over the mixed nature of the community.</p> / Master of Arts (MA)

The current trend in industry to encourage engineering designers to take an active part in the analysis of their own design solutions is apparent in many companies today, domestically as well as abroad. From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users’ lack of knowledge and experience in the design of lightweight structures and Computer-Based Design Analysis (CBDA). CBDA here refers to the use of analysis tools such as Finite Element Analysis (FEA) and computer-based structural optimization. In order to handle these difficulties, the author introduced the use of templates. In the given context, a template refers to an especially preformatted code, which contains the implemented information/knowledge necessary to perform a specific task on an operational level. It should be noted that the use of templates as a means of support in performing a specific design or analysis task is not a new phenomenon in industrial practice. Inspired by the opportunities provided by the template approach, the main objective set out for the thesis project was to facilitate the active participation of the engineering designers in performing CBDA singlehandedly, or in any other organizational setting, by utilizing a Template-Based Design Analysis (TBDA) approach, as an integrated part of their activities within the engineering design process. The evolutionary research approach for the development of the TBDA approach is based on surveys in Swedish as well as international industry, literature surveys, the development of a Generic Design Analysis (GDA) process model (facilitating integration of the activities between CBDA and engineering design) and a number of demonstrator projects to deepen the insights into TBDA. Note that as the TBDA approach is intended for use in industrial practice, the approach is independent of specific engineering design and product development processes utilized in industry. The conclusion of the thesis work clearly supports the claim that TBDA is not only a competitive approach to current alternatives in supporting the engineering designers performing CBDA, but also of a complementary nature providing functionality not included in the alternative approaches currently used in industrial practice. / Vid framtagning av nya produkter måste man utgå ifrån de behov som den blivande kunden ställer i form av krav och önskemål på produkten för att den ska vara intressant att inhandla och använda. För att säkerställa att den blivande produkten har de egenskaper som efterfrågas, används idag omfattande simuleringar av den blivande produktens egenskaper. Simuleringar består i avancerade beräkningar med hjälp av dator. Genom att utföra dessa tidigt i utvecklingsarbetet, så kan man väsentligen korta ned tiden för utveckling och konstruktion av produkten. Detta uppnås framför allt genom att minska behovet av att bygga och prova prototyper. Beräkningar i utvecklings- och konstruktionsarbetet spelar därför idag en väsentlig roll för att ta fram konkurrenskraftiga produkter på ett snabbt och effektivt sätt. I denna avhandling har ett nytt tillvägagångssätt tagits fram för att låta konstruktörer själva beräkna sina konstruktionsförslag. Hittills har merparten av alla beräkningar av detta slag genomförts av beräkningsingenjörer. Nu kan man genom att tillämpa den i avhandlingen framtagna tillvägagångssättet att med hjälp av digitala mallar (program för att lösa speciella uppgifter i konstruktionsarbetet) och det föreslagna tillvägagångssättet MallBaserad KonstruktionsAnalys (MBKA) tillåta att konstruktörer, som vanligtvis inte är specialister på beräkningar, självständigt kan utföra sådana analyser. Mallarnas roll är alltså att överbrygga brister i kompetens och erfarenheter av konstruktionsberäkningar. Redan idag finns konkurrerande sätt att tillåta konstruktörer att delta i beräkningsarbetet, men då oftast med direkt stöd av en beräkningsingenjör och med tillgång till riktlinjer. Dessa kräver att konstruktören har en viss grundkompetens för att kunna följa och tillämpa dessa. MBKA ställer inte dessa krav på kompetens och insikter, vilket gör att den kan betraktas inte bara som en konkurrent till existerande tillvägagångssätt utan också erbjuda ett helt unikt och nytt stöd genom att inte kräva kunskaper och insikter om konstruktionsberäkningar. Av de reaktioner som erhållits i intervjuer i svensk industri, så ter sig framtiden för MBKA som mycket lovande. Många företag funderar redan idag på att införa tillvägagångssättet. Innan så kan ske, måste dock MBKA utvecklas ytterligare, vilket är målet för den fortsatta forskningen. / <p>ISRN LUTMDN/TMKT-15/1032-SE</p>
