    In this thesis, application of Fuzzy Logic controller to the building energy management system using solar power system energy as a renewable energy source has been put into practice in smart home automation buildings. Solar panels with 2 photovoltaic system with 150 Watt force value and 2 accumulators with 12 V 200 Ah values were used in this hybride power system. The aim of this study is to provide the created system both work autonomous and grid connected. According to this purpose, including the grid connection failure providing energy permanence on managed loads is aimed. This process done by Fuzzy logic controllable building energy managament system. Energy which is produced by hybrid system, firstly charges accumulators and then is transfered to grid or loads. If the hybrid system doesn’t produce energy and batteries are empty, continuity of autonomous loads are compensated from city grid. Additionally before the connecting to the city grid, the controller can analyze home distribution system for supply to the life safety and most importance loads such as , fire alarm control system, access door system, wifi network and extar low voltage power supply. The most important factor here is to ensure the stability of the energy supply of important loads. Second issueis that, energy saving by opening unnecessary loads and also reducing unnecessary energy consumption in smart home systems through specially applied lighting, brightness, movement and precense sensors has been studied

    Exchange market pressure and currency crises in Turkey : an empirical investigation

    This thesis investigates the determinants of exchange market pressure and currency crises in Turkey over the period 1989:09 and 2001:04 using three empirical methodologies: the Autoregressive Distributed Lag (ARDL) bounds testing approach to investigate the short-run and the long-run dynamics of exchange market pressure; the binary logit and ordered logit models in order to identify the determinants of currency crises; and third, it applies the signals approach to identify the leading indicators of currency crises. The findings of the thesis have indicated that speculative pressure in the foreign exchange market and currency crises in Turkey in the sample period cannot be attributed entirely to a single cause and that these two phenomena are a result of a diverse set of factors. The results also suggest that both speculative pressure in the exchange market and currency crises in Turkey are linked to the reversals in the capital flows. The findings have also indicated that another important factor which has given rise to speculative pressure in the exchange market and currency crises in Turkey is the weaknesses in the banking sector balance sheets, such as the overexposure to foreign exchange, liquidity and credit risks. The results of the thesis have also revealed that currency crises and speculative pressure in the foreign exchange market are linked to the overvaluation of the Turkish lira. Above all, the results have indicated that currency crises and speculative pressure in the foreign exchange market are not necessarily driven by common factors and that it is misleading to classify explanatory variables strictly as statistically significant and insignificant in the context of currency crises. Last but not least, the findings of this thesis have also suggests that statistically insignificant variables could still convey information regarding the imminence of currency crises if used in a non-parametric signals model.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    Semantic discovery and reuse of business process patterns

    Get PDF
    Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

    INTERNAL AUDIT CHARACTERISTICS AND QUALITY OF ACCOUNTING INFORMATION IN NIGERIA

    Get PDF
    The basic goal of Accounting is to provide enabling accounting information for reliable decision-making. The quality level of this accounting information comes from the company's governance practices, thereby emphasizing the importance of corporate governance in companies. Recently, following the financial crises resulting in accounting scandals, attention has been moving towards Internal Audit Function as an important factor in the structure of Corporate Governance. This paper therefore examined the extent of the relationship between internal audit function and the quality of accounting information of companies. The study adopted the Survey research design. The research instrument employed was Questionnaire which was administered to internal auditors of the “Big Four”. Linear regression analysis was employed in the analysis of the data collected with the use of Statistical Packages for Social Sciences (SPSS). The results revealed that there is a significant relationship between the internal audit characteristics and the quality of accounting information. It was recommended that in order to provide credibility to the financial statement, there should be a law in place mandating attachment of internal auditors report to the financial statemen
