    Resilience, Reliability, and Recoverability (3Rs)

    Recent natural and human-made disasters, mortgage derivatives crises, and the need for stable systems in different areas have renewed interest in the concept of resilience, especially as it relates to complex industrial systems with mechanical failures. This concept in the engineering systems (infrastructure) domain could be interpreted as the probability that system conditions exceed an irrevocable tipping point. But the probability in this subject covers the different areas that different approaches and indicators can evaluate. In this context, reliability engineering is used the reliability (uptime) and recoverability (downtime) indicators (or performance indicators) as the most useful probabilistic tools for performance measurement. Therefore, our research penalty area is the resilience concept in combination with reliability and recoverability. It must be said that the resilience evaluators must be considering a diversity of knowledge sources. In this thesis, the literature review points to several important implications for understanding and applying resilience in the engineering area and The Arctic condition. Indeed, we try to understand the application and interaction of different performance-based resilience concepts. In this way, a collection of the most popular performance-based resilience analysis methods with an engineering perspective is added as a state-of-the-art review. The performance indicators studies reveal that operational conditions significantly affect the components, industry activities, and infrastructures performance in various ways. These influential factors (or heterogeneity) can broadly be studied into two groups: observable and unobservable risk factors in probability analysis of system performance. The covariate-based models (regression), such as proportional hazard models (PHM), and their extent are the most popular methods for quantifying observable and unobservable risk factors. The report is organized as follows: After a brief introduction of resilience, chapters 2,3 priorly provide a comprehensive statistical overview of the reliability and recoverability domain research by using large scientific databases such as Scopus and Web of Science. As the first subsection, a detailed review of publications in the reliability and recoverability assessment of the engineering systems in recent years (since 2015) is provided. The second subsection of these chapters focuses on research done in the Arctic region. The last subsection presents covariate-based reliability and recoverability models. Finally, in chapter 4, the first part presents the concept and definitions of resilience. The literature reviews four main perspectives: resilience in engineering systems, resilience in the Arctic area, the integration of “Resilience, Reliability, and Recoverability (3Rs)”, and performance-based resilience models

    The files on this record represent the various databases that originally composed the CD-ROM issue of "Abstracts on Radio Direction Finding" database, which is now part of the Dudley Knox Library's Abstracts and Selected Full Text Documents on Radio Direction Finding (1899 - 1995) Collection. (See Calhoun record https://calhoun.nps.edu/handle/10945/57364 for further information on this collection and the bibliography). Due to issues of technological obsolescence preventing current and future audiences from accessing the bibliography, DKL exported and converted into the three files on this record the various databases contained in the CD-ROM. The contents of these files are: 1) RDFA_CompleteBibliography_xls.zip [RDFA_CompleteBibliography.xls: Metadata for the complete bibliography, in Excel 97-2003 Workbook format; RDFA_Glossary.xls: Glossary of terms, in Excel 97-2003 Workbookformat; RDFA_Biographies.xls: Biographies of leading figures, in Excel 97-2003 Workbook format]; 2) RDFA_CompleteBibliography_csv.zip [RDFA_CompleteBibliography.TXT: Metadata for the complete bibliography, in CSV format; RDFA_Glossary.TXT: Glossary of terms, in CSV format; RDFA_Biographies.TXT: Biographies of leading figures, in CSV format]; 3) RDFA_CompleteBibliography.pdf: A human readable display of the bibliographic data, as a means of double-checking any possible deviations due to conversion

    Ecological Understanding through Transdisciplinary Art and Participatory Biology

    Full version unavailable due to 3rd party copyright restrictionsIn this study evidence is presented that suggests transdisciplinary art practices and participatory biology programs may successfully increase public understanding of ecological phenomenon. As today’s environmental issues are often complex and large-scale, finding effective strategies that encourage public awareness and stewardship are paramount for long-term conservation of species and ecosystems. Although artists and biologists tend to stay confined to their professional boundaries, and their discourses largely remain inaccessible to larger audiences, arguments here are presented for a combined approach, which may disseminate knowledge about ecology to non-specialists through novel art-science participatory research and exhibitions. Moreover, historically several scientists utilized varied creative art forms to disseminate scientific insights to a larger populace of non-specialists, such strategies as engaging writings and visually provocative artworks may still be effective to captivate contemporary audiences. In addition such historic hybrid science-art practitioners may have laid a conceptual terrain for some of today’s transdisciplinary art and citizen science practices. Furthermore, seminal ecological artworks from the 20th Century by Joseph Beuys, Patricia Johanson and Hans Haacke utilized novel strategies to reach audiences with a message of wetland conservation, blurring boundaries between art, ecology and activism. More recently artists like Cornelia Hesse-Honegger, Helen and Newton Harrison and others have integrated biological research into their art practices, which resulted in new scientific discoveries. Through my own transdisciplinary artwork about frogs, data suggests that the visual strategies I employ were effective to increase non-specialist understanding of the ecological phenomenon of amphibian declines and deformations. In addition through my participatory biology programs, Public Bio-Art Laboratories and Eco-Actions, evidence suggests that non-specialists achieved an increased awareness of the challenges amphibians and ecosystems currently face. Likewise, that through such participatory citizen science research new scientific insights about the proximate causes for deformities in anuran amphibians at select localities in middle England and Quebec were achieved. Here laboratory and field evidence, generated with the aid of public volunteers, found that non-lethal predatory injury to tadpoles from odonate nymphs and some fishes resulted in permanent limb deformities in post-metamorphic anurans. From an environmental-education and larger conservation standpoint, these findings are very relevant as they offer novel strategies for experientially engaging non-specialist audiences while generating important insights into biological communities and wetland ecosystems

    The regulation of innovation

    Get PDF
    This thesis has proposed a fourth model of contact between patient and doctor, that of innovation. The law fails to recognise this and therefore uses principles established in the context of a normal therapeutic doctor patient relationship to determine negligence in cases of innovation. Innovation in turn can take two forms, experimental or personal. The law treats experimentation as if it were normal therapy and is thus too benevolent towards experimenters. The courts currently accept the use of experimental treatment merely no the grounds that a responsible body of medical opinion supports its use. However, it has been argued that the law should change to require the experimenters to justify their actions. On the other hand, with respect to personal innovation and learning new techniques, the law of negligence is too harsh, taking no account of the need for doctors to learn and develop their skills, which is in the interests of future patients. Some suggestions have been proposed to overcome this. In summary, the benefit of recognising that innovation is a separate model of contact between doctor and patient is that it will be fairer to both parties. Two important issues have been raised. Firstly, the context in which the innovative treatment of either variety is administered needs to be taken into consideration by the courts. Standard laws of negligence, based on principles established when considering the normal doctor-patient relationship, do not take this into account. Secondly, the question of what information is disclosed to the patient regarding this innovation also needs to be considered. The doctor should inform the patient, either that the treatment proposed was experimental, or that he or she was inexperienced in the particular technique proposed. Primarily this should lead to better protection from risk for patients and allow them the choice of whether to proceed. However, it is also fairer to the doctor and provides better protection, as the patient cannot then claim that he or she was not fully informed and the realities of medical practice are respected
