The nature of semistructured data in web collections is evolving. Even when XML web documents are valid with regard to a schema, the actual structure of such documents exhibits significant variations across collections for several reasons: an XML schema may be very lax (e.g., to accommodate the flexibility needed to represent collections of documents in RSS feeds), a schema may be large and different subsets used for different documents (e.g., this is common in industry standards like UBL), or open content models may allow arbitrary schemas to be mixed (e.g., RSS extensions like those used for podcasting). A schema alone may not provide sufficient information for many data management tasks that require knowledge of the actual structure of the collection. Web applications (such as processing RSS feeds or web service messages) rely on XPath-based data manipulation tools. Web developers need to use XPath queries effectively on increasingly larger web collections containing hundreds of thousands of XML documents. Even when tasks only need to deal with a single document at a time, developers benefit from understanding the behaviour of XPath expressions across multiple documents (e.g., what will a query return when run over the thousands of hourly feeds collected during the last few months?). Dealing with the (highly variable) structure of such web collections poses additional challenges. This thesis introduces DescribeX, a powerful framework that is capable of describing arbitrarily complex XML summaries of web collections, providing support for more efficient evaluation of XPath workloads. DescribeX permits the declarative description of document structure using all axes and language constructs in XPath, and generalizes many of the XML indexing and summarization approaches in the literature. DescribeX supports the construction of heterogenous summaries where different document elements sharing a common structure can be declaratively defined and refined by means of path regular expressions on axes, or axis path regular expression (AxPREs). DescribeX can significantly help in the understanding of both the structure of complex, heterogeneous XML collections and the behaviour of XPath queries evaluated on them. Experimental results demonstrate the scalability of DescribeX summary refinements and stabilizations (the key enablers for tailoring summaries) with multi-gigabyte web collections. A comparative study suggests that using a DescribeX summary created from a given workload can produce query evaluation times orders of magnitude better than using existing summaries. DescribeX’s light-weight approach of combining summaries with a file-at-a-time XPath processor can be a very competitive alternative, in terms of performance, to conventional fully-fledged XML query engines that provide DB-like functionality such as security, transaction processing, and native storage.

In recent years we have witnessed an increase in the number of two unrelated phenomena in Canada collaborative partnerships and First Nations casino development. This thesis focuses on the integration of these two phenomena by examining the gaming partnership that the Federation of Saskatchewan Indian Nations (FSIN) and the Province of Saskatchewan established in 1995. The thesis explores the factors that produced the partnership, the issues of negotiations that influenced the partnership arrangement, and the general nature of the partnerships framework from 1995 to 2002. In analyzing these aspects of the partnership, the thesis will address its fundamental question what is the precise nature of the regulatory framework and its implications for the gaming partnership in Saskatchewan? This study reveals that there were deficiencies in the nature of the partnerships framework, particularly with respect to the accountability provisions of the partnering arrangement. Those deficiencies created an accountability crisis in the year 2000, which caused problems both for and between the partners. Eventually, however, the partners decided to move forward in a relatively positive and constructive manner towards a sustainable and successful partnering arrangement.

Wind energy provides an environmentally friendly and renewable source of electricity, that can help meet Canada's Kyoto commitments, help safeguard against future blackouts, reduce air pollution and create economic opportunities in the form of manufacturing jobs and land leases for farmers. From a land use planning perspective, however, wind turbines create challenges that municipalities and planners have to deal with more frequently. Ontario in particular lags behind countries such as Ireland and Australia in terms of providing a clear, equitable and comprehensive land use planning framework to deal with wind energy. <br /><br /> What is lacking in particular is a clear understanding of how Ontario municipalities are dealing with the issue of wind energy developments, whether the policies that are being developed adhere to good planning principles, what are the land use planning issues that are impacting wind energy development in Ontario and what are some recommendations that could be made to improve wind energy policies. A secondary goal of this thesis was to identify common elements of good wind energy planning frameworks that could be used to develop wind energy planning policies in the City of Stratford, which currently does not have any policies or a wind energy land use planning framework and is also where the author is employed as the City Planner. <br /><br /> To address this lack of information, this report focuses on the current state of wind energy planning policy development in southwestern Ontario and in particular; the types of wind energy planning frameworks have been developed in the world, the elements of "good" planning principles and frameworks and whether or not they are found in these frameworks, whether there are components of these policies that would be appropriate for wider adoption in Ontario and finally, what types of framework should the City of Stratford develop for wind energy? <br /><br /> To address these questions, a literature review was conducted on wind energy land use planning issues and examples of international wind energy planning guidelines were reviewed. Additionally, five southwestern Ontario municipalities with wind energy policies were selected as case studies and Planners and other wind energy stakeholders were interviewed. <br /><br /> This study found that the main issues and barriers surrounding wind energy planning policy development in Ontario are visual impact, lack of education and a lack of a municipal planning framework. It was also determined that, the public reaction to wind energy proposals in Southwestern Ontario has been mostly positive and the conflicts that have arisen have been in instances where wind turbines are proposed in the vicinity of recreational properties. In terms of a wind energy planning framework, southwestern Ontario municipalities have for the most part opted for General Official Plan policies supporting wind energy development in principle and directing its development to certain land use designations subject to a zoning by-law amendment. The planning frameworks in the case studies for the most part conform to good planning principles identified, however, there was a large variation between the municipalities in terms of the level of detail within the planning framework. Finally, it was determined that the City of Stratford Official Plan and Zoning By-law are inadequate in terms of policy and regulations for wind energy. <br /><br /> This study recommends that the Ontario Provincial Government should follow up on the Wind Energy Information Sheet and the recent Provincial Policy Statement with a comprehensive land use-planning framework for wind energy developments that should borrow on existing international guidelines that have been developed. This study also recommends that the City of Stratford should update its Official Plan to include policies that address wind energy generation, should initiate a study to determine if there are any areas within the City that are considered to be natural heritage views or areas that should be protected from the visual impacts of wind energy production, should investigate permitting wind energy facilities in certain industrial areas of the City, subject to a zoning by-law amendment and should work with the County of Perth to develop a common set of zoning by-law regulations for wind energy developments.

This thesis aims to apply the reinforcement learning into soccer robot and show the great power of reinforcement learning for the RoboCup. In the first part, the background of reinforcement learning is briefly introduced before showing the previous work on it. Therefore the difficulty in implementing reinforcement learning is proposed. The second section demonstrates basic concepts in reinforcement learning, including three fundamental elements, state, action and reward respectively, and three classical approaches, dynamic programming, monte carlo methods and temporal-difference learning respectively. When it comes to keepaway framework, more explanations are given to further combine keepaway with reinforcement learning. After the suggestion about sarsa algorithm with two function approximation, artificial neural network and tile coding, it is implemented successfully during the simulations. The results show it significantly improves the performance of soccer robot.

The Water Framework Directive (WFD, 2000/60/EC) was introduced in 2000. In implementing the WFD in Sweden expert knowledge in areas relating to the WFD was much needed resulting in establishment of national water management authorities, as the five water authorities, boarded in appointed county administrative boards across the country. As much noted in literature, uncertainties appear when implementing the WFD. Previous literature,with the exception of e.g. Raadgever et al (2011), Brugnach et al (2008) and Sigel et al (2007 and2010), has not put much focus on the types of uncertainty experienced by water management officials working with the implementation of the WFD on a daily basis. There are also few studies in Sweden, such as Gipperth &amp; Elmgren (2010), Hammer et al (2011) and Entson &amp; Gipperth(2010), touching upon the subject although not entirely focusing on practical experiences of uncertainty. Therefore, the aim of this study is to reveal the types of uncertainties experienced by water management officials from: SMHI, the county administrative board in Östergötland and Bothnia Bay, the water authority in the Southern Baltic Sea district, the Northern Baltic Sea and the North Sea, as well as the SEPA. In analysing the empirical data, six types of uncertainties emerged. They showed that water management officials experienced uncertainties in interpreting the WFD e.g. recommendation and manuals from supervisory authorities, measurement techniques, the typology of water bodies, what methods to use in e.g. assessments, knowing the effects of action programmes and lack of data ordata deficiency. In combating these uncertainties, the water management officials used communication as an strategy. Furthermore, responsibility in pointing out uncertainties and ways of reducing uncertainties was also seen as ways of handling uncertainties.

In the world of modeling, Model Validation plays a crucial role. A model editor is not said to becomplete without Validation. ModelicaML is a Modeling Language extended from a subset of UMLand SysML, developed under OpenModelica Project. It is defined to provide time-discrete andtime-continuous models. Papyrus Model Editor is extended to support for ModelicaML usingModelicaML Eclipse plug-in. This plug-in comes with Modelica Code Generator.Previously, ModelicaML plug-in had a prototype of validation which provided only Batch-modevalidation. The validation is used to be done by the Modelica compiler after the code generation phase.Each time the user tried to validate the model; first Modelica code is generated and then validated. Thistype of validation misses certain validation rules to validate due to the conversion from theModelicaML model to Modelica code.The goal of this thesis is to implement Model Validation done at model editor level with both Batch andLive mode validation. This can be done by developing an Eclipse plug-in which does the ModelValidation. This plug-in uses the EMF Validation framework for implementing the constraints andvalidation on ModelicaML models.

Although markets are emerging for commercial off-the-shelf components (such as Sun JavaBeans), there are many barriers to widespread component adoption. This is due to the inherent `black-box' nature of software components: developers have no knowledge or control of the component's internal characteristics. Without source or design details, developers only have the component's interface, documentation and test results to answer important questions about reliability, proper use, behavior andperformance. The current best practice of specifying a component's capabilities by providing only the syntax and informal documentation is insufficient to assemble mission or safety-critical systems successfully. To address these problems we have developed a framework forcreating and analyzing the concise specifications of components and their related interfaces. The framework extends a formal model for software architecture descriptions to support the specification of a range of terms. With formal component specifications developers can use the framework to analyze the properties of individual components or of entire systems. Unlike other approaches, the formal basis and implementation of our framework enhance understanding and automates much of thecomponent analysis process.
