An approach to parallelize the simulation of AC-Radial Shipboard Power Systems (SPSs) using multicore computers is presented. Time domain simulations of SPSs are notoriously slow, due principally to the number of components, and the time-variance of the component models. A common approach to reduce the simulation run-time of power systems is to formulate the electrical network equations using modified nodal analysis, use Bergeron's travelling-wave transmission line model to create subsystems, and to parallelize the simulation using a distributed computer. In this work, an SPS was formulated using loop analysis, defining the subsystems using a diakoptics-based approach, and the simulation parallelized using a multicore computer. A program was developed in C# to conduct multithreaded parallel-sequential simulations of an SPS. The program first represents an SPS as a graph, and then partitions the graph. Each graph partition represents a SPS subsystem and is computationally balanced using iterative refinement heuristics. Once balanced subsystems are obtained, each SPS subsystem's electrical network equations are formulated using loop analysis. Each SPS subsystem is solved using a unique thread, and each thread is manually assigned to a core of a multicore computer. To validate the partitioning approach, performance metrics were created to assess the speed gain and accuracy of the partitioned SPS simulations. The simulation parameters swept for the performance metrics were the number of partitions, the number of cores used, and the time step increment. The results of the performance metrics showed adequate speed gains with negligible error. An increasing simulation speed gain was observed when the number of partitions and cores were augmented, obtaining maximum speed gains of <30x when using a quadcore computer. Results show that the speed gain is more sensitive to the number partitions than is to the number of cores. While multicore computers are suitable for parallel-sequential SPS simulations, increasing the number of cores does not contribute to the gain in speed as much as does partitioning. The simulation error increased with the simulation time step but did not influence the partitioned simulation results. The number of operations caused by protective devices was used to determine whether the simulation error introduced by partitioning SPS simulations produced a inconsistent system behavior. It is shown, for the time step sizes uses, that protective devices did not operate inadvertently, which indicates that the errors did not alter RMS measurement and, hence, were non-influential.

In this thesis, we have compared between dual-core fiber coupler with photonic crystal fiber coupler. From Surface Integral Equation Method derived from Maxwell¡¦s equations, we can simulate tapered fiber coupler, dual-core fiber coupler and photonic crystal fiber coupler. By analyzing the propagating characteristics and performance of these couplers, we hope to discuss between their advantages and dis-advantages. We have found that at the same parameters, conventional fiber coupler¡¦s coupling length is roughly half compared to photonic crystal coupler. In terms of bandwidth, photonic crystal coupler aided by air-hole tuning can achieve multiples times larger than conventional fiber coupler. So, we believe that in communication networks with a lust of bandwidth, photonic crystal coupler can definitely live up its expectations.

In this study we discuss the Vehicle Routing Problem with multiple use of vehicles (VRPM). In this variant of the routing problem the vehicles may replenish at any time at the depot. We present a detailed review of existing literature and propose two mathematical models to solve the VRPM. For these two models and their several variants we provide computational results based on the test problems taken from the literature. We also discuss a case study in which we are simultaneously dealing with side constraints such as time windows, working hour limits, backhaul customers and a heterogeneous vehicle fleet.

In this thesis work, the symptoms in Windows XP operating system for fault monitoring are investigated and a fault monitoring library is developed. A test GUI is implemented to examine this library. Performance tests including memory and CPU usage are done to see its overhead to the system and platform tests on the current version of Windows operating system series (Windows Vista) are done to see for compatibility. In this thesis, fault monitor-fault detector interface is also defined and implemented. To monitor a symptom that is not implemented in the monitoring library, projects can implement their own monitors. A monitoring framework is designed to control and coordinate these monitors with the main one. To create monitors for Java projects easily, a monitor creator library is developed.

This study aims to improve transportation held between six auction centers, Inter-Auction Transportation, of FloraHolland. FloraHolland serves ninety eight percent of the Dutch market and is the largest auction in floriculture industry. The company wants to give the best sale opportunities with the costs as low as possible and this is the main initiative of this study. In this line of thought, FloraHolland wants to have a improvement on its current routing and scheduling mechanism. Exact models do not work due to the complexity and the size of the problem. Therefore, we developed a two-stage approach specific to this study. With this approach, we split exact approach into two, a mathematical model followed by a heuristic. In the exact approach, trucks are routed and scheduled at the same time. On the other hand, our solution approach first determines most efficient routes to be followed with Cycle Assignment Model and then, with Scheduling Heuristic, trucks are assigned to the routes, so within day transportation is planned in detail. Overall, each stage of this approach works in harmony and brings good solutions in a short CPU time.

A single-mode fused biconical 2¡Ñ2 coupler for polarization beamsplitting is fabricated in this thesis. We use simple fused and tapered method to fabricate the polarization beamsplitter(PBS) stably, and then we can get polarization maintaining in the output fibers. Without changing the manufacturing process, we design the device with special combination of fabrication parameters. We have achieved an extinction ratio of 25.78dB at the throughput port and 27.16dB at the coupled port. A usable spectral window as broad as 37nm and 27nm with an extinction ratio larger than 15dB for both ports is obtained. The excess loss is about 0.3dB. Based on a full-wave numerical approach, the performance of the PBS can be well modeled. We get good agreement between the measured and simulated results.

<p>Rapporten undersöker om det är möjligt att använda Clonezilla för distribuerad installation av Windows Vista som alternativ till Symantec Ghost. Ett ytterligare krav är att installationen ska vara automatiserad och inte kräva något extra arbete efter installationens slut. Dessutom ska datorerna vara redo att användas i en Windows-domän efter en färdig installation.</p><p>Programmet Clonezilla är av typen open source och är fritt att använda medan Symantec Ghost är en kommersiell produkt som kräver flertalet licenser beroende på antalet datorer. Clonezilla körs i Linux och saknar grafiskt gränssnitt, Symantec däremot har ett eget gränssnitt för att överskådligt hantera datorer och distribuera operativsystem i välkänd Windows-miljö. Båda lösningarna testas under flera praktiska experiment i labbmiljö. De två programmen jämförs och utvärderas gällande prestanda och användarvänlighet.  Resultaten visar på att skillnaden gällande prestanda är marginell. Gällande användarvänlighet är skillnaden för de båda programmen större då Symantec erbjuder ett grafiskt gränssnitt tillsammans med hjälpavsnitt för produkten. Båda lösningarna fungerar för ändamålet och har olika fördelar respektive nackdelar.</p>

<p>The transfer system was created in order to control player movement between football clubs and has existed since the late nineteenth century. During the negotiation of today’s transfer rules FIFA, UEFA and the Commission found that a breach of contract during the season could upset the balance of competition and therefore should be restricted. It was considered necessary to strengthen the contractual stability and to apply a special rule to preserve the regularity and proper functioning of competition. This was done by the means of a provision stipulating that a football player only can be registered to play with a national association during one of the two registration periods per year, generally known as the transfer windows.</p><p>Sport has never been included in the formal structures of the European Union and the regulation of sport has instead materialized through verdicts from the European Court of Justice. One of the most influential statements emerging from the Court is that sport is subject to Community law in so far it constitutes an economic activity. Consequently, if the activity is economic there is a risk that it infringes EU law. The purpose of this master thesis is to examine the FIFA transfer window system and to determine whether it violates Article 39 and/or Article 81 EC.</p><p>The transfer windows, a regulation strengthened by the ECJ in the case of <em>Lehtonen</em>, restrict the ability of players to seek alternative employment and could therefore be regarded as a violation of the free movement of workers. In order to trigger the Treaty provisions guarding the right of freedom of movement the person in question must be a national of a Member State of the European Union and the activity must have a territorial dimension beyond the borders of a single Member State of the European Union. The person in question must also be engaged in some kind of economic activity. It is, however, clear that football players who are members of the European Union and are applying for a job in another Member State, and are performing at a certain level, fulfil these requirements. Footballers should therefore be considered as workers within the meaning of Article 39 EC and the prohibition of discrimination contained in that article which catches non-discriminatory private collective measures, such as the transfer system, invented by regulatory bodies like FIFA and UEFA.</p><p>When considering the FIFA “windows system” it is clear that it is liable of restricting the ability of players to seek alternative employment in another Member State and should therefore be regarded as a violation of Article 39 EC. Nevertheless, restricted transfer periods have been found by the ECJ to be objectively justified as having sporting benefits in the Belgian Basketball league. It is, however, likely that the “window system”, as it operates in European football, goes beyond what is necessary to achieve team and player contract stability since it is too restrictive and somewhat redundant. Consequently, the FIFA transfer windows do not comply with the requirements of the principle of proportionality and should therefore, if challenged, be regarded as a violation of Article 39 EC.</p><p>The use of transfer windows in European football can also be considered to be an issue for competition law and in particular Article 81 EC. The article prohibits all agreements between undertakings that restrict competition and affect trade between Member States and has the objective to protect consumers, enhance their welfare and to facilitate the creation of a single European market. The ECJ has, however, acknowledged a certain type of sporting rule that, even though it restricts competition, will be granted immunity from Article 81 EC. The FIFA “windows system” should not be regarded as such a rule since it does not fulfil the required conditions.</p><p>The transfer windows do little for the competitive balance within the European football. It may be argued that it preserves the appeal and the unpredictability of the finishing stages of a championship. However, they also prevent clubs from developing their economic activity and restrict the free play of the market forces of supply and demand. Furthermore, the “windows system” hinders certain clubs from raising the quality of their sporting performance since clubs in minor leagues with a closed window are losing their best players to clubs in a better league with an open window, without being able to replace them. All of this affects the small and economically weak clubs and strengthens the position of the financially strong clubs. As a result a few strong clubs will, contrary to the best interest of consumers, continue to dominate European football. The FIFA regulation of transfer windows is therefore likely to fall under Article 81(1) EC.</p><p>It is unlikely that the pro-competitive benefits of the FIFA transfer windows outweigh its restrictive effects since it is improbable that they would be considered the least restrictive means of creating these benefits. Subsequently, the FIFA “windows system” would not qualify for an exemption under Article 81(3) EC and should, if challenged, be void under Article 81(2) EC.</p>
