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. 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. The transfer windows, a regulation strengthened by the ECJ in the case of Lehtonen, 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. 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. 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. 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. 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.

Cloud computing is emerging as a promising platform for compute and data intensive scientific applications. Thanks to the on-demand elastic provisioning capabilities, cloud computing has instigated curiosity among researchers from a wide range of disciplines. However, even though many vendors have rolled out their commercial cloud infrastructures, the service offerings are usually only best-effort based without any performance guarantees. Utilization of these resources will be questionable if it can not meet the performance expectations of deployed applications. Additionally, the lack of the familiar development tools hamper the productivity of eScience developers to write robust scientific high performance computing (HPC) applications. There are no standard frameworks that are currently supported by any large set of vendors offering cloud computing services. Consequently, the application portability among different cloud platforms for scientific applications is hard. Among all clouds, the emerging Azure cloud from Microsoft in particular remains a challenge for HPC program development both due to lack of its support for traditional parallel programming support such as Message Passing Interface (MPI) and map-reduce and due to its evolving application programming interfaces (APIs). We have designed newer frameworks and runtime environments to help HPC application developers by providing them with easy to use tools similar to those known from traditional parallel and distributed computing environment set- ting, such as MPI, for scientific application development on the Azure cloud platform. It is challenging to create an efficient framework for any cloud platform, including the Windows Azure platform, as they are mostly offered to users as a black-box with a set of application programming interfaces (APIs) to access various service components. The primary contributions of this Ph.D. thesis are (i) creating a generic framework for bag-of-tasks HPC applications to serve as the basic building block for application development on the Azure cloud platform, (ii) creating a set of APIs for HPC application development over the Azure cloud platform, which is similar to message passing interface (MPI) from traditional parallel and distributed setting, and (iii) implementing Crayons using the proposed APIs as the first end-to-end parallel scientific application to parallelize the fundamental GIS operations.

In this study, we consider the Air Cargo Scheduling Problem based on a real life application. The aim is to move cargo and passengers that have different priorities and delivery time window, from a number of origin airports to destination airports by means of a transportation system. The system has predefined carrier routes and a heterogeneous fleet of aircraft. The problem is formulated as a heterogeneous vehicle, multi commodity, pick-up, and delivery network flow problem with a large set of system specific constraints. The proposed model determines set of movement requirements assigned on each route leg and number and type of aircraft assigned for each route in a reasonable amount of time. The model is tested with the real and generated data and the results are compared with the current methodology under different scenarios. The model produced better results in a short amount of time compared to the current methodology.

ISA extensions are a very powerful approach to implement new hardware techniques that require or benefit from compiler support: decisions made at compile time can be complemented at runtime, achieving a synergistic effect between the compiler and the processor. This thesis is focused on two ISA extensions: predicate execution and register windows. Predicate execution is exploited by the if-conversion compiler technique. If-conversion removes control dependences by transforming them to data dependences, which helps to exploit ILP beyond a single basic-block. Register windows help to reduce the amount of loads and stores required to save and restore registers across procedure calls by storing multiple contexts into a large architectural register file.In-order processors specially benefit from using both ISA extensions to overcome the limitations that control dependences and memory hierarchy impose on static scheduling. Predicate execution allows to move control dependence instructions past branches. Register windows reduce the amount of memory operations across procedure calls. Although if-conversion and register windows techniques have not been exclusively developed for in-order processors, their use for out-of-order processors has been studied very little. In this thesis we show that the uses of if-conversion and register windows introduce new performance opportunities and new challenges to face in out-of-order processors.The use of if-conversion in out-of-order processors helps to eliminate hard-to-predict branches, alleviating the severe performance penalties caused by branch mispredictions. However, the removal of some conditional branches by if-conversion may adversely affect the predictability of the remaining branches, because it may reduce the amount of correlation information available to the branch predictor. Moreover, predicate execution in out-of-order processors has to deal with two performance issues. First, multiple definitions of the same logical register can be merged into a single control flow, where each definition is guarded with a different predicate. Second, instructions whose guarding predicate evaluates to false consume unnecessary resources. This thesis proposes a branch prediction scheme based on predicate prediction that solves the three problems mentioned above. This scheme, which is built on top of a predicated ISA that implement a compare-and-branch model such as the one considered in this thesis, has two advantages: First, the branch accuracy is improved because the correlation information is not lost after if-conversion and the mechanism we propose permits using the computed value of the branch predicate when available, achieving 100% of accuracy. Second it avoids the predicate out-of-order execution problems.Regarding register windows, we propose a mechanism that reduces physical register requirements of an out-of-order processor to the bare minimum with almost no performance loss. The mechanism is based on identifying which architectural registers are in use by current in-flight instructions. The registers which are not in use, i.e. there is no in-flight instruction that references them, can be early released.In this thesis we propose a very efficient and low-cost hardware implementation of predicate execution and register windows that provide important benefits to out-of-order processors.

Shading devices have the potential to reduce peak cooling load and annual energy consumption because they can be used to control solar gain. Thus, the need to model shading devices in a glazing system analysis is important. This thesis deals with various measurement techniques and model development related to solar optics in windows with shading devices. It also considers longwave radiative properties of shading devices via model development and experimentation. The different shading devices examined were roller blinds, insect screens, pleated drapes and venetian blinds. The energy performance of windows with shading devices was modeled using a two step procedure. Solar radiation was considered in the first step by developing a multi-layer solar optical model for glazing/shading systems. This newly developed model is an extension of an existing model for systems of specular glazing layers and includes the effect of layers that create scattered, specifically diffuse, radiation in reflection and/or transmission. Spatially-averaged (effective) optical properties were used to characterise shading layers, including their beam-diffuse split. The multi-layer solar optical model estimates the system solar transmission and absorbed solar components. The absorbed solar components appear as energy source terms in the second step – the heat transfer analysis. The heat transfer analysis involves the formulation of energy balance equations and requires both effective longwave properties and convective heat transfer coefficients as input. The simultaneous solution of the energy balance equations yields the temperature as well as the convective and radiative fluxes. The effective solar optical properties of flat materials like drapery fabrics, roller blinds and insect screens were obtained by developing a new measurement technique. Special sample holders were designed and fabricated to facilitate measurements using an integrating sphere installed in a commercially available spectrophotometer. Semi-empirical models were then developed to quantify the variation of solar optical properties with respect to incidence angle. In turn, effective layer properties of venetian blinds and pleated drapes were modeled using a more fundamental net radiation scheme. The effective longwave properties of flat materials were obtained by taking measurements with an infrared reflectometer using two backing surfaces. The results enabled simple models to be developed relating emittance and longwave transmittance to openness, emittance and longwave transmittance of the structure. In turn, effective longwave properties of venetian blinds and pleated drapes were modeled using a net radiation scheme. Convective heat transfer correlations were readily available. Finally, the newly developed models were validated by measuring the solar gain through various shading devices attached to a double glazed window using the National Solar Test Facility (NSTF) solar simulator and solar calorimeter. Solar gain results were also obtained from simulation software that incorporated the models. There was good agreement between the measured and the simulated results thus strengthening confidence in the newly developed models.
