This research is dedicated to make a foreseeing of the future state of the Kizildere Geothermal Field in order to suggest acceptable solutions to the current problems. The non-isothermal mechanism of the geothermal field is simulated for the pressure and temperature variables. For this purpose, a finite element model (696 four-nodal elements with 750 nodes) of the field is formulated by considering the geological conditions and the present wells already drilled in the area. Then the model is calibrated to the field for the natural state by using appropriate physical properties, boundary and initial conditions. Comparison of the simulated and the observed pressures and temperatures has emphasized a very successful calibration study. After the calibration, response of the field to the production and injection for the period of 1984-2006 has been simulated by applying a history matching study. History matching runs have yielded very good correlations between the observed and the computed values of the pressure and temperature variables. The calibrated and history matched model has been applied to the field to simulate the future performance of the field for different production and injection scenarios. In the first scenario the field is simulated for the next 10-year production period keeping the on-going production conditions. Then, the influence of the production of two new wells has been investigated in two different scenarios. In the forth scenario, the effect of injection from one of the production wells has been simulated.

The purpose of this thesis is to examine the difference between SVO and OVS sentences in spoken Russian, which is a language with flexible word order although the basic order is SVO. Two experiments were conducted to understand the nature of intonation. Experiment 1 shows that the Subject appears as kontrast in OVS sentences, and as background in SVO sentences. The F0 curve rises in the Object position when the Subject is kontrast in OVS sentences. The analysis of the results of Experiment 2 shows that the initial element of the sentence plays an important role in intonation. When it is kontrasted, it always has higher (Hz) frequency pitch accent than the final element. There is no difference between SVO and OVS sentences in this respect because the initial element has high pitch accent, whether it is the Subject or the Object. The verb has no pitch accent and it has a flat intonation regardless of the WO of the sentence (SVO, OVS).

Even though construction components account for more than fifty percent of the total installed costs, industry practices still solely rely on the human ability to individually track thousands of these components on the site. These primitive tracking processes are inefficient, error-prone, and can significantly hinder project performance. Thus, previous research efforts observed that up to eighteen percent of craft work-hours was attributable to the unavailability of components required for installation. Recently, though, the notion that these ineffective tracking processes can highly benefit from the implementation of information technologies (IT) has gained industry acceptance. However, the reality is that this IT influence on construction performance has not yet been addressed. The objectives of this study are (1) to develop a methodology for the automated identification and localization of engineered components on large industrial projects, and (2) to assess and to quantify the impact of this automating tracking process on project performance. The identification and localization methodology is proposed based on the combination of advanced sensing devices and localization algorithms. The integration of global positioning system (GPS) and radio frequency identification (RFID) receivers facilitates a network-free data collection process capable of detecting the presence of large numbers of RFID-tagged components almost instantly. Based on the collected data, localization algorithms precisely estimate the coordinates of the tagged items. The precision of this automated approach is validated by means of lab and field experiments. Complementarily, the impact of this localization methodology on project performance was quantified during an extensive field trial on a large industrial site. For this purpose, field records from manual and automated tracking processes were collected during the trial. Then, the influence of the automated tracking process on construction performance was determined by considering the manual approach as the baseline for comparison. The results demonstrate that information technologies can significantly enhance project performance. / text

Maximising student attainment is a key issue for every secondary school. Student attainment can be improved by raising their information literacy levels. It is part of a school librarian’s role to promote these skills. This is complicated by the absence of information literacy in secondary school curricula, teachers’ low awareness of the concept and the lack of teacher training in the professional education of librarians. There are a range of definitions and different approaches to teaching information literacy published leading to conflict over choices. Overall there is a lack of empirically tested pedagogy, particularly for synthesis and assessment. This research explores what it means to be information literate and addresses the fundamental question of ‘How can we raise information literacy levels in a secondary school? The research strategy explored the teachers’ perspectives to ascertain their perceptions of information literacy, how it is currently taught by them and their understanding of the librarian’s role. The research was conducted in a secondary school where semi-structured interviews were used with a sample of twelve teachers selected by age, experience and subject. The analysis examined three diverse teacher voices and compared these with insights from the remaining nine teachers’ perspectives. The research findings show that teachers view information literacy differently. This is shaped by the role of information in their subject’s approach to learning. Student progress to higher information literacy levels requires a pedagogy that is situated in subject teaching, rather than generic sessions, with clarity of how skills are deployed in different subject contexts to support learning transfer and work that is differentiated to meet different learning needs. Conceptually it was found that information literacy is contingent upon the context in which it is being used. A new instrument has been designed depicting progress in information literacy to stimulate thinking about possible pedagogy and assessment.

This thesis presents research conducted at the University of Warwick in improving Web 2.0 (or Social Web) authoring, by semi-adaptively recommending data via Information Retrieval methods. Thus this research integrates two main areas, Semantic Web and Information Retrieval. The research has led to a tool for retrieving semantic web data and reusing the retrieved data in authoring Wikipedia pages. The goal of this tool is firstly to enable semantic web crawling with a user friendly interface, by applying a semantic web framework API to an existing web archiving system and, secondly, to find an easy way for reusing the data in authoring, by implementing a delivery engine for the retrieved data. To demonstrate this new tool, this thesis presents example scenarios for retrieving semantic data from a specified domain and utilizing the drag and drop method in authoring. The presented paradigm is evaluated via two case studies, following the two versions of the prototype, and future work is discussed.

M. Tech. Business Information Systems / Companies that can effectively manage available information as they generate competitive intelligence without experiencing information overload are leaders in their industry. The research focus on how to avoid or manage causes of information overload while using Internet technologies to gather or collect intelligence during the competitive intelligence gathering. Furthermore, this study focused on this issue in the context of competitive intelligence as its field of application. The objective of this study was to develop and test a model to be used for developing guidelines for avoiding or managing causes of information overload when using Internet technologies to conduct the competitive intelligence process.

M. Tech. Business Information Systems / Information Systems (IS) capability can be viewed as a firm's valuable resources, and if controlled well, can contribute towards competitive and efficient business value. For the purpose of this study, IS capability is thus defined as the firm's ability to continuously derive business value from Information technology (IT) investments, and this includes the firm's IT personnel skills and competencies. The research argument driving the study was that IS capability is an outcome of good IS management and IT governance. However, to date, IS capability has not been defined beyond an expression of the firm to derive and leverage business value through IS continuously. Consequently, this dissertation conceptualizes a framework towards IS capability in a South African firm. In the study, IS capability is seen as achieved through a sound IT governance, IT management, and corporate governance. That is, the study was about how governance and management of IS happens in a typical firm. IS capability was studied by looking at how the firm makes IT decisions, prioritizes IT investments, business and IT collaborating to create the vision, IT leadership, and the management of information systems resources.

M. Tech. Business Information Systems / In today's Information Society, organizations have to ensure clean and secure data in order to make informed decisions. However, maintaining secure data need systematic Information Security Management. It is important to note that much as Information Security Management is considered the pillar of Enterprise Information Systems, its challenges are numerous. These challenges may include; loss of cooperate information, compromise of sensitive data and continuous cracking into the organization network systems. Academic institutions like many other information based organizations go through a wave of these challenges. Such challenges if not effectively handled could lead to serious security breaches. This study sought to identify metrics needed for Information Security Management in Universities of Technology.
