Повний текст джерелаVirtuella maskiner är idag i hjärtat av en stor del av den kod som styr våra dagliga liv. Deras prestanda och funktionalitet är indirekt mycket viktig för samhället och få har så stor påverkan som JVM:en. I den här uppsatsen så undersöker vi möjligheten att snabba upp stack tracing på Hotspot och OpenJDK genom att implementera en returbarriär. Den här barriären implementeras genom att skriva över returprogramräknaren med en som pekar till en funktion som installerar sig själv på ramen under varje gång den körs. På grund av detta så går den att använda som ett lågvattenmärke och vi utnyttjar detta för att få Java Flight Recorder att kunna återanvända den delen av stacken som redan har traverseras tidigare. Även om det första försöket inte var framgångsrikt när det kommer till att snabba upp prestandan så tar vi en detaljerad titt på kostnaderna och fördelarna med de olika stegen i implementationen och ger råd i hur man skulle kunna använda en sådan här barriär i framtiden.

The cost of photovoltaic systems has declined more rapidly than other electricity production technologies, while nuclear plant costs have risen. Changing costs have contributed to global energy transitions in the past, and our capacity to decarbonize the electricity sector will depend on the cost of low-carbon electricity production technologies like photovoltaic and nuclear energy. Understanding the mechanisms behind historical cost evolution and potential future improvement can inform the design of energy technologies and the policies that advance them. This thesis investigates historical barriers and future opportunities for cost reduction in solar and nuclear power. By developing innovative mathematical and conceptual models, we address the following questions: (1) How can "plug-and-play" design improve costs in photovoltaic systems? (2) What were the sources of cost escalation and overruns in nuclear power plant construction? We address these questions in chapters 2 and 3.
Chapter 2 assesses the potential for plug-and-play designs to reduce non-module costs in photovoltaic systems. This work advances use of the design structure matrix for studying cost change in energy technologies by evaluating design factors across multiple systems. We identify the cost components with significant latent potential for improvement--profit, installation labor, overhead, electrical balance of system, and customer acquisition--and show that plug-and-play designs have advantageous effects on their constituent parts. A conventional small-scale photovoltaic project contains nearly 600 interactions across 30 or more system elements; we show that plug-and-play designs can reduce the number of interactions by two-thirds and elements by half.
Several mechanisms are important to the cost change potential of plug-and-play technology: eliminating various project tasks or shifting their responsibility to the consumer removes the associated overhead and profit of installation firms; pre-assembly of system components and standardization of project tasks eliminates installation labor costs; reduction and simplification of BOS electrical components lowers equipment costs; and standardization of system design precludes time-intensive tasks involved in customer acquisition. We compare the advantages of prevailing plug-and-play designs and consider future opportunities for technological innovation and policy advancement. Chapter 3 examines the engineering assumptions underlying many nuclear cost models using historical cost data from the U.S. nuclear industry. We show that expectations for technological improvement may have underestimated factors external to hardware design.
By mapping separate cost trajectories for standard plant designs, we find that nth-of-a-kind (NOAK) plants have been more expensive than first-of-a-kind (FOAK) plants, counter to traditional expectations. Indirect costs external to technological design were responsible for most of the cost rise observed between 1976 and 1987. Decomposition of cost changes in the reactor containment building shows that while safety was a significant factor driving cost increases, non-safety factors were comparably influential. Comparing productivity data from recent U.S. plant construction to industry expectations, we find that material deployment rates are up to thirteen times slower than cost estimating guidelines suggest. We discuss which technologies could potentially lower the impact of external, previously cost-increasing factors, with the support of regulatory changes and R&D.

Повний текст джерелаTwo major Open Science innovations, Open Access and research data sharing, have been studied in detail in this thesis. A large-scale survey and personal interviews are used to gain detailed insights from a range of disciplines. In addition, a case study in the High Energy Physics (HEP) community was used to study the results in practice. The results show that a rather positive attitude towards both, Open Access and research data sharing is not reflected in the researchers’ practices. Disciplinary differences prevail and relate to the different publishing cultures and research workflows. The results indicate that quality and prestige of research output are perceived as very important in determining a researcher’s reputation. Researchers prefer community-approved publication outlets. They hesitate to explore new innovations, such as data sharing, for which only few established workflows exist in digital scholarly communication. Interviewees highlight the significance of a (missing) link between such approaches on the one hand and the current incentive system and the research assessment schemes on the other. The results indicate that barriers can be overcome. In the case study, a strong collaboration with the community facilitated enhanced feedback loops to develop tailored and targeted services for Open Science. Researchers in the case study were successfully engaged in new innovative workflows: a crowdsourcing tool and data sharing in a digital library. The results highlight that opportunities of Open Science are not yet explored widely. But with targeted support, it is possible to build on best practices and develop strategies that engage communities in new innovations. The results furthermore demand new strategies to establish links from Open Science services to the academic incentive system. It is needed to revisit the current research assessment scheme in regard to potential support mechanisms for Open Science.

Повний текст джерелаTiivistelmä Tämä väitöskirja käsittelee yksinkertaisen sadantaan perustuvan konseptuaalisen vesitasemallin kehitystä ja soveltamista boreaalisille valuma-alueille sekä malliin liittyvää alueellista parametrisointia valuma-alueominaisuuksien ja ilmastoaineiston perusteella. Hydrologinen malli on luotu laskemaan ja ennustamaan valuntaa pohjoisille valuma-alueille, joilta on vähän hydrologista tietoa. Malli yhdistää lumen kertymisen ja sulannan tunnettuun sadantaindeksiin perustuvaan malliin (CPI) ja edelleen simuloi päivittäisen hydrografin valuma-alueille, joilla on selkeä lumipeitteinen ajanjakso. Malli laskee MaxBas funktion avulla CPI:llä muodostetun hydrografin päivittäiseksi valunnaksi valuntaan liittyvien malliparametrien CT ja Lf sekä virtaaman kynnysarvon ThQ avulla. Malli kehitettiin Excel-ympäristössä ja sitä testattiin 32 valuma-alueella Suomessa. Valuma-alueet edustivat maantieteellisesti kattavasti alueita, joilla esiintyy tyypillisesti kausittainen lumipeite. Saadut tulokset osoittivat, että kehitetty malli simuloi ja tuottaa päivittäisen valunnan riittävällä tarkkuudella valuma-alueille, vaikka hydrologista ja fysikaalista tietoa alueilta olisi niukasti. Useimmat malliparametrit olivat vahvasti riippuvaisia joko valuma-alue ominaisuuksista tai ilmastollisista parametreista tai molemmista. Parametrien funktionaalinen yhteys muodostettiin valuma-alueiden ominaisuuksien perusteella ja testattiin riippumattomalla valuma-aluejoukolla hyvin tuloksin. Malliparametrien samatavoitteellisuutta eli ekvifinaliteettiä voitiin vähentää huomioimalla mallissa lumen vesiarvomittaukset sekä hyödyntämällä useita parametrisia funktioita. Tällöin myös optimaalisten parametrien löytyminen nopeutui ja helpottui. Tämän väitöstyön pohjalta syntynyt uusi sadannan indeksiin pohjautuva laskentamalli (CPIsnow) mahdollistaa valunnan arvioinnin pieniltä valuma-alueilta, joilta on niukasti aineistoa saatavilla ja joissa lumen sulanta ja kertyminen ovat keskeisiä hydrologisia prosesseja

Повний текст джерелаBACKGROUND: Patient navigation programs were designed to address barriers to healthcare among underserved populations in order to reduce delays in cancer care delivery. While emerging data suggest modest effects of navigation on reducing delays, there is limited understanding of the association between barriers to care and clinical outcomes within patient navigation programs. OBJECTIVE: To investigate the impact of barriers on timely diagnostic care in the multicenter Patient Navigation Research Program (PNRP). STUDY DESIGN: Secondary analysis of data from the intervention arms of PNRP centers that navigated women for abnormal breast or cervical cancer screening tests from 2007 to 2010. METHODS: Analyses were performed separately for breast and cervical subjects. The main independent variables were (a) number of unique barriers to care (0, 1, 2, or 3+) documented during patient navigation encounters and (b) presence of socio-legal barriers (yes/no), those social problems related to meeting life’s most basic needs that are supported by public policy, regulation, and programming and thus potentially remedied through legal advice or advocacy. The outcome of interest was median time to diagnostic resolution, or the interval from index screening abnormality to diagnostic resolution, estimated using Kaplan-Meier cumulative incidence curves. Multivariable Cox proportional hazards regression with time to diagnostic resolution as the outcome examined the impact of barriers, controlling for socio-demographics and stratifying by study center. RESULTS: Among 2600 breast screening subjects, three-quarters had barriers to care (25% 1 barrier, 16% 2 barriers and 34% 3+ barriers). Among 1387 cervical screening subjects, slightly more than half had barriers (31% 1 barrier, 11% 2 barriers, and 13% 3+ barriers). Among breast subjects, we found the presence of barriers was associated with less timely resolution for any number of barriers compared to no barriers. Among cervical subjects, only the presence of 2 or more barriers was associated with less timely resolution. Both socio-legal and non socio-legal barriers were associated with delay among breast and cervical subjects. CONCLUSIONS: Navigated women with barriers resolve cancer screening abnormalities at a slower rate compared to those with no barriers. Further research is necessary to maximize the impact of patient navigation programs nationwide.

Thesis, Jönköping University, JIBS, Business Informatics, 2010. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-12464.
Повний текст джерелаIntroduction: Along with the rapid spread of the World Wide Web, internet, and personal computers, e-learning has been increasingly adopted by higher educational institutions (HEIs). A serial of studies have been conducted in order to study the implementation of e-learning in HEIs. This study is a comparative study of two Chinese universities and one Swedish university. It is trying to answer the following research questions:
- What are teachers’ attitudes towards e-learning and purpose for using it?
- What are the driving factors and barriers of e-learning implementation?
- How do national cultures influence the e-learning implementation?
Purpose: This study is conducted as an explorative study. It is seeking to find out driving factors and barriers of e-learning implementation in HEIs; Analyse the impact of national culture on e-learning implementation based on the findings and the analysis out of Hofstede´s culture dimension model.
Method: The deductive approach will be adopted in this study. Therefore, a hypothesis has been built and tested by both primary and secondary data. Primary data was collected through questionnaires and the secondary was collected from internet resources, books, published articles and conference papers.
Conclusion: There are similarities and differences between universities from the two countries, however, the differences are relatively greater than the similarities. Taken into consideration the significant differences in culture of these two countries, the conclusion can be drawn that national culture is a significant ingredient of factors that can affect e-learning implementations in HEIs.

Повний текст джерелаNum mundo onde cada vez mais a informação se encontra facilmente disponível, surgem novos desafios à proteção dos dados pessoais dos cidadãos. O tema da proteção de dados pessoais tem ganho crescente importância no contexto atual, isto porque a informação é cada vez mais um bem fundamental e por isso mesmo tem de ser devidamente protegida, pois uma simples divulgação de dados pode causar danos irreversíveis, quer a um nível micro, quer a um nível macro. Deste modo importa conhecer o que a União Europeia já fez e o que está a fazer nesta matéria. Assim, com base neste contexto, o trabalho que aqui se apresenta pretende identificar os fatores (barreiras e facilitadores) que influenciam a implementação e aplicação das diretivas comunitárias de proteção de dados pessoais em Portugal. Para a identificação destes fatores, optámos por uma metodologia de natureza qualitativa e realizámos entrevistas semi-estruturadas a quatro profissionais da área da proteção de dados pessoais. Para a realização da investigação recorremos ainda à pesquisa bibliográfica, análise documental, participação em conferências e entrevistas exploratórias. Na fase de resultados e após a análise de conteúdo das entrevistas, concluiu-se que das catorze questões incorporadas no guião, treze questões são facilitadores do processo de aplicação das diretivas comunitárias de proteção de dados pessoais em Portugal, umas com maior incidência do que outras. No entanto conseguimos identificar as questões com mais facilitadores e com mais barreiras, identificando assim as condições de sucesso e de insucesso para a aplicação das diretivas. Neste trabalho indicamos as diretivas de proteção de dados pessoais e as respetivas leis que as transpõem. A realização deste trabalho permitiu ainda abordar questões importantes no âmbito da proteção de dados pessoais, como é o caso dos direitos dos titulares dos dados, das obrigações dos responsáveis pelo tratamento dos dados ou ainda a Comissão Nacional de Proteção de Dados.
In a world where more and more information is easily available, there are new challenges to the protection of personal data of citizens. The issue of personal data protection has gained increasing importance in the current context, this is because information is increasingly a fundamental and must be properly protected, because a simple disclosure of data can cause irreversible damage, either to a micro level, either at the macro level. Thus it is important to know what the European Union has done and what it is doing in this area. Thus, based on this context, the work presented here aims to identify the factors (barriers and facilitators) that influence the implementation and application of EU directives of personal data protection in Portugal. To identify these factors, we opted for a qualitative methodology and held semi-structured interviews to four professionals in the field of personal data protection. To carry out the research we use also to literature, document analysis, participation in conferences and exploratory interviews. In the results and after the content analysis of the interviews, it was concluded that the fourteen issues incorporated in the script, thirteen issues are facilitators of the process of application of community directives of personal data protection in Portugal, with higher incidence than other. However we can identify the issues with more facilitators and more barriers, identifying the conditions of success and of failure to implement the directives. In this work we indicate the personal data protection directives and the respective laws that transposes. This work also helped to address important issues in the protection of personal data, such as the rights of data subjects, the obligations of data controllers or the National Data Protection Commission.

The aim of this study was to analyze the impact of the 2008 financial crisis on Paraná´s exports through Gravity Model. The Gravity Equation estimated used as the dependent variable the exports of Paraná and as independent variables the Gross Domestic Product (GDP) and population of the state, GDP and population of importers countries of products from Paraná, the distance in kilometers between the state´s capital and the capital of the importer country, commodities prices in the international market, the area of importers countries and the dummies crisis, China, NAFTA, European Union and MERCOSUR. The Equation was estimated using panel data models by Pooled, Fixed Effects and Random Effects. The tests of Chow, Hausman and Breusch-Pagan LM indicated that the best model to be analyzed is the Random Effects. The tests of Breusch -Pagan and Wooldridge indicated, respectively, the presence of heteroscedasticity and autocorrelation. Thus, the Random Effects model was estimated with heteroscedasticity correction, with correction for autocorrelation and both fixes. According to the Equation estimated by the Random Effects model with heteroscedasticity and autocorrelation correction, the variables GDP and population of Paraná, GDP and population of importers countries and commodities prices were statistically significant and their coefficients showed, with the exception of the Paraná´s GDP, a positive relationship with the Paraná´s exports. The variables distance and area of importers countries were statistically insignificant and their coefficients showed an inverse relationship with exports of Paraná. The dummies China, NAFTA, European Union and MERCOSUR were statistically insignificant. Their coefficients showed a positive relationship between the Paraná´s exports and China and MERCOSUR and negative with NAFTA and the European Union. The dummy crisis was statistically significant, indicating that reduction in demand caused by the global financial crisis led to a reduction of 11,68% in Paraná´s exports. However, between 2008 and 2009, the Paraná´s exports fell by 26,3%. Thus, the occurrence of crisis partially explained the drop in exports of Paraná between 2008 and 2009. This can be explained by non-tariff barriers imposed by countries in response to the financial crisis.
O objetivo deste estudo foi analisar o impacto da crise financeira de 2008 nas exportações do Paraná através do Modelo Gravitacional. A Equação Gravitacional estimada utilizou como variável dependente as exportações do Paraná e como variáveis independentes o Produto Interno Bruto (PIB) e a população do estado, o PIB e a população dos países importadores de produtos paranaenses, a distância em quilômetros entre a capital do estado e a capital do país importador, o preço das commodities no mercado internacional, a área dos países importadores e as dummies crise, China, NAFTA, União Europeia e MERCOSUL. A Equação foi estimada por meio de dados em painel pelos modelos Pooled, de Efeitos Fixos e de Efeitos Aleatórios. Os testes de Chow, Hausman e LM de Breusch-Pagan indicaram que o melhor modelo a ser analisado é o de Efeitos Aleatórios. Os testes de Breusch-Pagan e de Wooldridge indicaram, respectivamente, a presença de heterocedasticidade e de autocorrelação. Assim, o modelo de Efeitos Aleatórios foi estimado com correção de heterocedasticidade, com correção de autocorrelação e com ambas as correções. De acordo com a Equação estimada pelo modelo de Efeitos Aleatórios com correção de heterocedasticidade e autocorrelação, as variáveis PIB e população paranaense, PIB e população dos países importadores e preço das commodities foram estatisticamente significativas e seus coeficientes indicaram, com exceção do PIB do Paraná, relação positiva com as exportações paranaenses. As variáveis distância e área dos países importadores foram estatisticamente insignificantes e seus coeficientes mostraram uma relação inversa com as exportações do Paraná. As dummies China, NAFTA, União Europeia e MERCOSUL foram estatisticamente insignificantes. Seus coeficientes indicaram relação positiva entre as exportações paranaenses e a China e o MERCOSUL e negativa com o NAFTA e a União Europeia. A dummy crise foi estatisticamente significativa, indicando que redução da demanda global ocasionada pela crise financeira acarretou redução de 11,68% nas exportações paranaenses. Entretanto, entre 2008 e 2009, as exportações paranaenses apresentaram queda de 26,3%. Assim, a ocorrência da crise explicou parcialmente a queda das exportações do Paraná entre 2008 e 2009. Isto pode ser justificado pelas barreiras não tarifárias impostas pelos países em resposta à crise financeira.

Повний текст джерелаThe study of unbound nuclei beyond the drip-lines allows us to test our understand- ing of the atomic nucleus under extreme conditions. In this thesis, we have analyzed two separate GANIL experiments in which fluorine 15, located two proton beyond the proton drip-line, was studied. One of the interesting particularity of this nucleus is the presence of particularly narrow negative parity states, above the Coulomb and centrifugal barriers. In this work, we were interested in theses states. We have confirmed the existence of the second excited state 1/2- and have observed two new states, a 5/2- state and a 3/2- state by measuring their decay by emitting either one or two protons. The structure of these states has been discussed and we have tried to explain the origin of the asymmetry observed between the 3/2- state of fluorine 15 and its analogue state in carbon 15. We have also detailed the possibility of gamma transitions between unbound states

Повний текст джерелаIn the Pinheira regressive barrier, four coastal depositional environments are recognized, characterized by geological parameters such as lithofacies analysis, sedimentary structures, compaction degree and set of mollusks. Information that is analyzed together with images of geophysical data obtained with the Ground Penetrating Radar (GPR) method to determine these environments. The present work aims to characterize these depositional environments by analyzing the signal amplitude in traces with central frequencies antennas of 80, 100, 200 and 400 MHz in conjunction with the compaction and lithological data of a drill hole. It also shows the behavior of signal attenuation in relation to the humidity present in the environment. The analysis of the traces allowed the identification of the contacts between the environments already described for regressive barriers, showing variation in the value of the amplitudes (decrease or increase), together with the variation in the degree of compaction, which evidences in subsurface the change between the environments of foredune ridges, backshore/foreshore and upper and lower shoreface. The interference of humidity in attenuation of the signal in the studied data can be observed only in the first 0.5 m. Rainfall was not relevant for signal attenuation in the studied sandy deposits with water level close to the surface. The analysis of the radargrams for all the antennas allowed the identification of the patterns of reflectors already described for the environments of the study area and the central frequency antenna of 200 MHz showed the highest resolution for the definition of all the environments.

Повний текст джерелаShifting trips to electric cargo bikes is one possible solution to deal with the growing challenges of urban commercial transport. This thesis combines conceptual, transport-related, and economic aspects as a foundation to assess the feasibility of this vehicle concept for freight and service trips. It contains five scientific papers, which provide three research contributions. The first contribution identifies the potentials of electric cargo bikes among first users (i.e., courier logistics services). Electric cargo bikes are an updated and re-envisioned version of freight bicycles. The features of point-to-point courier logistics assignments offer a substantial market opportunity for electric cargo bikes. However, being positioned between two established modes (i.e., car and bicycle) handicaps the market entry of cargo bikes. For the second contribution, the scope was widened to include all business sectors. A structured description is presented of the various determinants (i.e., drivers and barriers) affecting commercial cargo bike use. Among these were vehicle-specific factors, structures and practices of the company, attitudes of decision-makers, soft factors, regulatory frameworks, and spatial conditions. The third contribution explores the travel time differences between electric cargo bikes and cars for commercial trips. For trip distances of up to 3 kilometers, the travel times of both modes largely overlap. Half of all trips up to 20 kilometers would take only a maximum of 2 to 10 minutes longer by electric cargo bike (excluding the additional time for finding a parking spot). Small modifications in traffic could have considerable effects in reducing the current travel time advantages of cars. Consequently, this dissertation contributes towards the state-of-research by expanding the scientific knowledge of a type of vehicle that has the potential to disrupt car-dependent transportation systems.
