Proceedings of the GIS Research UK 18th Annual Conference GISRUK 2010

This volume holds the papers from the 18th annual GIS Research UK (GISRUK). This year the conference, hosted at University College London (UCL), from Wednesday 14 to Friday 16 April 2010. The conference covered the areas of core geographic information science research as well as applications domains such as crime and health and technological developments in LBS and the geoweb. UCL’s research mission as a global university is based around a series of Grand Challenges that affect us all, and these were accommodated in GISRUK 2010. The overarching theme this year was “Global Challenges”, with specific focus on the following themes: * Crime and Place * Environmental Change * Intelligent Transport * Public Health and Epidemiology * Simulation and Modelling * London as a global city * The geoweb and neo-geography * Open GIS and Volunteered Geographic Information * Human-Computer Interaction and GIS Traditionally, GISRUK has provided a platform for early career researchers as well as those with a significant track record of achievement in the area. As such, the conference provides a welcome blend of innovative thinking and mature reflection. GISRUK is the premier academic GIS conference in the UK and we are keen to maintain its outstanding record of achievement in developing GIS in the UK and beyond

Optimal seismic retrofitting of existing RC frames through soft-computing approaches

2016 - 2017Ph.D. Thesis proposes a Soft-Computing approach capable of supporting the engineer judgement in the selection and design of the cheapest solution for seismic retrofitting of existing RC framed structure. Chapter 1 points out the need for strengthening the existing buildings as one of the main way of decreasing economic and life losses as direct consequences of earthquake disasters. Moreover, it proposes a wide, but not-exhaustive, list of the most frequently observed deficiencies contributing to the vulnerability of concrete buildings. Chapter 2 collects the state of practice on seismic analysis methods for the assessment the safety of the existing buildings within the framework of a performancebased design. The most common approaches for modeling the material plasticity in the frame non-linear analysis are also reviewed. Chapter 3 presents a wide state of practice on the retrofitting strategies, intended as preventive measures aimed at mitigating the effect of a future earthquake by a) decreasing the seismic hazard demands; b) improving the dynamic characteristics supplied to the existing building. The chapter presents also a list of retrofitting systems, intended as technical interventions commonly classified into local intervention (also known “member-level” techniques) and global intervention (also called “structure-level” techniques) that might be used in synergistic combination to achieve the adopted strategy. In particular, the available approaches and the common criteria, respectively for selecting an optimum retrofit strategy and an optimal system are discussed. Chapter 4 highlights the usefulness of the Soft-Computing methods as efficient tools for providing “objective” answer in reasonable time for complex situation governed by approximation and imprecision. In particular, Chapter 4 collects the applications found in the scientific literature for Fuzzy Logic, Artificial Neural Network and Evolutionary Computing in the fields of structural and earthquake engineering with a taxonomic classification of the problems in modeling, simulation and optimization. Chapter 5 “translates” the search for the cheapest retrofitting system into a constrained optimization problem. To this end, the chapter includes a formulation of a novel procedure that assembles a numerical model for seismic assessment of framed structures within a Soft-Computing-driven optimization algorithm capable to minimize the objective function defined as the total initial cost of intervention. The main components required to assemble the procedure are described in the chapter: the optimization algorithm (Genetic Algorithm); the simulation framework (OpenSees); and the software environment (Matlab). Chapter 6 describes step-by-step the flow-chart of the proposed procedure and it focuses on the main implementation aspects and working details, ranging from a clever initialization of the population of candidate solutions up to a proposal of tuning procedure for the genetic parameters. Chapter 7 discusses numerical examples, where the Soft-Computing procedure is applied to the model of multi-storey RC frames obtained through simulated design. A total of fifteen “scenarios” are studied in order to assess its “robustness” to changes in input data. Finally, Chapter 8, on the base of the outcomes observed, summarizes the capabilities of the proposed procedure, yet highlighting its “limitations” at the current state of development. Some possible modifications are discussed to enhance its efficiency and completeness. [edited by author]XVI n.s

Understanding modes of dwelling: A transdisciplinary approach to phenomenology of landscape

This transdisciplinary PhD addresses the research question: Can some form of phenomenology provide an effective over-arching paradigm for transdisciplinary research in ethnophysiography? Ethnophysiography studies the way people within a language community conceptualise natural landscape, including terms for landscape features and toponyms (placenames). Dwelling involves conceptualisations and affects regarding physical, utilitarian, cultural, spiritual and ethical relationships with landscape. A key achievement is development of an enhanced ethnophysiography case study methodology, supporting the Ethnophysiography Descriptive Model (EDM). Summary phenomenographic tables were prepared from literature reviews of ethnophysiography, transdisciplinarity, phenomenology, concepts of place and relationships with place. The use of tables, summarising key results of literature reviews (via a phenomenographic approach), is integral to the methodology, to operationalize transdisciplinarity. Some tables are utilised in the PTM-ECS, facilitating identification of relevant issues, collection of appropriate data, and hermeneutic analysis processes. To facilitate comparison of landscape terms and toponyms between languages, the EDM was developed and tested. A key contribution is interpretation of the phenomenological concepts of ‘lifeworld’, ‘topology’ and ‘habitus’. Creation of landscape, as place, involves synergistic integration, in a non-deterministic and emergent manner, of the physical attributes of an area of topographic environment (terrain and ecosystem) with the socio-cultural characteristics of a group of people (including linguistic and spiritual aspects). This produces a particular topo-socio-cultural-spiritual mode-of-dwelling (topology). A partial trial of the new methodology is provided, via an ethnophysiography case study with Manyjilyjarra Aboriginal people in Australia’s Western Desert (undertaken by this author with linguist Clair Hill). It demonstrates how the adopted approach facilitates understanding of traditional forms of dwelling and how this relates to Jukurrpa (The Dreaming), the law, lore and social structure of their society. Review of research processes indicates they effectively utilised key features of transdisciplinarity. A summary of the findings, their potential application, a statement of research limitations, and proposals for further research, are provided
