In 1989, the Tiananmen Square massacre shocked the world. Under the heavy pressure from Congress and the public opinion, the government of the United States, which regarded human rights as one of its most cherished values, was forced to reexamine its relations with the PRC and to pay more attention to the PRC¡¦s human rights issues. However, the Cliton administration chose to de-link the human rights issue from its consideration whether to give the PRC the MFN status. To Beijing, the human rights issue is only a tool in Washington¡¦s foreign policy. China regards human rights as its domestic affairs. It had always questioned Washington¡¦s purpose and motivation to intervene mainland China¡¦s domestic affairs. This thesis studies the factor of human rights in the U.S.-China relations. U.S. Congress used MFN as an annual check about China¡¦s human rights situation. Before 2000, U.S. Congress members had long time questioned the administration that grantee PNTR would lead to the destruction of China¡¦s motivation about human right improvement. The author intends to review the ¡§Human Right Report¡¨ in the period of Cliton¡¦s administration, trade relations, UN human right debate and bills. Besides, the progress of China¡¦s human rights situation will be evaluated in the thesis. Through the review of the human right factor in the Sino-US relations, we can find that how the strategy of human right been used by U.S. government. However, the human right issue still is one of the important factors which could affect the future Sino-US relations.

This dissertation presents a high-precision positioner with a novel superimposed concentrated-field permanent-magnet matrix. This extended-range multi-axis positioner can generate all 6-DOF (degree-of-freedom) motions with only a single moving part. It is actuated by three planar levitation motors, which are attached on the bottom of the moving part. Three aerostatic bearings are used to provide the suspension force against the gravity for the system. The dynamic model of the system is developed and analyzed. And several control techniques including SISO (single input and single output) and MIMO (multi inputs and multi outputs) controls are discussed in the dissertation. The positioner demonstrates a position resolution of 20 nm and position noise of 10 nm rms in x and y and 15 nm rms in z. The angular resolution around the x-, y-, and z-axes is in sub-microradian order. The planar travel range is 160 mm ?? 160 mm, and the maximum velocity achieved is 0.5 m/s at a 5-m/s2 acceleration, which can enhance the throughput in precision manufacturing. Various experimental results are presented in this dissertation to demonstrate the positioner??s capability of accurately tracking any planar trajectories. Those experimental results verified the potential utility of this 6-DOF high-precision positioner in precision manufacturing and factory automation.

Numerous research efforts have been devoted to characterizing the behavior of granular materials, which is one of the main concerns of pavement engineers. For better understanding of this behavior, laboratory tests where in-situ stress conditions and traffic loads are adequately simulated are needed. This study makes use of an expanded test protocol called a performance test that includes resilient modulus as well as permanent deformation testing. This test protocol determines three nonlinear resilient modulus parameters (k1, k2, k3) and two permanent deformation parameters (?,??). The resilient modulus test results are required inputs in the Level 1 analysis of the proposed American Association of State Highway and Transportation Officials (AASHTO) Pavement Design Guide. In addition, both resilient modulus and permanent deformation test results provide material property inputs to pavement performance prediction models. This study also evaluated the within laboratory repeatability of the performance test and developed a within laboratory precision statement. Further, a statistical analysis was conducted on the test results to estimate the number of test specimens required for testing for specific reliability levels. Two test specimens are required for a reliability level of 15%. A within laboratory study was also conducted to investigate the influence of specimen size on test results. The specimen height was reduced from 12 in. (304 mm) to 8 in. (203 mm), and there was no difference in test results at a confidence level of 95%. The performance test was further used successfully in subsequent studies to evaluate the behavior of granular materials and the influence of various factors on their behavior. As fines content increased, the resilient modulus values decreased and permanent deformation increased. As the moisture content increased, the resilient modulus value decreased and the resistance to permanent deformation decreased. A simplified laboratory measurement tool that is repeatable, relatively cheap and easy to perform might prompt the use of laboratory measured values of resilient modulus in pavement design and facilitate correlation of these values to field measured values on a large scale. Use of measured data for the base properties rather than estimates would insure improved pavement designs and, in many cases, would save money in construction costs.

The EEC (Electron Energy Corporation) in conjunction with the National Aeronautics and Space Administration is researching the magnetic bearings for an alternative to conventional journal or ball bearings. The purpose of this research was to design and develop a high-temperature (1000ºF) hybrid Magnetic Bearing using High Temperature Permanent Magnets (HTPM), developed by the EEC for high performance jet engines at high speeds that supply loads of 500 lbf. Another objective is to design and build a test rig fixture to measure the load capacity of the designed bearing. The permanent magnet bias of the Homopolar radial magnetic bearing reduces the amount of current required for magnetic bearing operation. This reduces the power loss due to the coil current resistance and improves the system efficiency because the magnetic field of the HTPM can suspend the major portion of the static load on bearing. A high temperature radial magnetic bearing was designed via an iterative search employing 3D finite element based electromagnetic field simulations. The bearing was designed to produce 500 lbf of force at 1000ºF and the design weight is 48 lbs. The bias flux of the Homopolar radial bearing is produced by EEC HTPM to reduce the related ohmic losses of an electromagnetic circuit significantly. An experimental procedure was developed to measure actual load capacity of the designed bearing at the test rig. All the results obtained from the experiment were compiled and analyzed to determine the relation between bearing force, applied current and temperature.

Advances in electrical machinery with high efficiencies could significantly reduce the cost of industrial and residential energy systems, thereby reducing fossil fuel needs and emissions. Electrical machine design is a comprehensive process based on several factors, including economic factors, material limitations, specifications and special application-dependent factors. At the same time, machine design is a multi-physics task comprising of electric design, magnetic design, insulation design, thermal design and mechanical design. However, the out-of-date conventional machine design can neither reflect the advances in the past 30 years, nor exploit the trade-offs between design factors from the multi-physics nature of the electrical machine. This work focus on the development a fast and efficient method for the design and optimization of Surface Mount Permanent Magnet (SMPM) machines and induction machines, as influenced by the energy source, mechanical loads, thermal effects, and the up-to-date developments in materials and manufacturing capabilities. A new analytical design method is developed for the electromagnetic design of SMPM machines. Both distributed and concentrated winding types of SMPM machines are considered and compared. Based on the proposed electromagnetic analytical design method and a generic thermo-mechanical machine design model [1], an innovative and computationally efficient electromagnetic-thermo-mechanical integrated design method is developed for SMPM machines. Particle Swarm Optimization (PSO) is applied in a novel way based on this integrated design method for the multi-objective design optimization of SMPM machines. With the proposed method, the thermal and mechanical design is no longer treated separately and heuristically as in the traditional design, but has been systemically integrated with the electromagnetic design; the effect of power source, cooling capability, thermal limits, and up-to-date material capabilities are also reflected in the design and optimization. Superior designs compared to traditional designs can be achieved with PSO based multi-objective optimization. The proposed integrated design approach also has the merit of good computational efficiency and provides a significant time reduction of the design cycle compared to finite element analysis. A novel electromagnetic analytical design method of induction machines has been developed, which needs only six prime design variables but is able to design induction machines in fine details. The advantage over the traditional and other existing design method is that this proposed method does not have the heuristic selection of the design variables and does not need manual design iterations. The computing time is almost negligible and the design cycle is significantly reduced compared to the tradition machine design.

<p>The European Union (EU) is built on the principle of freedom of establishment, meaning that companies have the possibility to establish themselves as a company or by setting up a secondary establishment in other Member States. This right has been confirmed by the European Court of Justice through case law.</p><p>A basic feature in domestic tax legislation is that losses are allowed to be set off against profits when calculating the tax liability of a company. At the moment cross-border loss compensation within the EU is restricted, unfeasible or just accepted on a temporary basis. This lack of recognition of loss-offset gives the fact that double taxation may occur and claims form two or more national tax systems leads to uncertainty in the way a company will be taxed. Depending on whether the secondary establishment is a subsidiary or a branch, the rules relating to loss compensation differs.</p><p>Taxation of secondary establishments is based on the principle of whether or not they are considered as a resident or a non-resident of the state. In regards to taxation of secondary establishments, the PE is considered to be a non-resident and a subsidiary considered to be a resident. However, the European Court of Justice approach of non discriminatory treatment and equal treatment that has been developed and seen in the history of case law leads to the question if the Marks & Spencer ruling that concerned secondary establishments in form of subsidiaries can be applied to permanent establishments.</p><p>The most vital difference between a subsidiary and a permanent establishment is connected to the taxation of the two. The subsidiary is considered to become a resident of the establishing state while the permanent establishment is seen as a non-resident. This legal difference between the two leads to different treatment under tax law. Taxation under a tax treaty leads to the situation where one of the contracting states will either credit or exempt the income deriving from the permanent establishment. Permanent establishments are often taxed under the method of exemption.</p><p>In the Marks & Spencer case it was held that losses and profits were two sides of the same coin. Applying this statement to permanent establishments gives the notion that if a contracting state exempts an income, there will be a set off of the symmetry of having losses and profits within the same tax system. This lead to the fact that if applying the Marks & Spencer ruling on permanent establishments that are taxed under the exemption method, allowing terminal losses to be taken into account at the head office will set off the symmetry. Therefore it can be considered as the Marks & Spencer ruling shall not apply to permanent establishments.</p>

<p>This licentiate thesis describes the modeling and measurements performed with the aim of developing design guidelines for Line Start Permanent Magnet Synchronous Motors, LSPMSMs. LSPMSMs can offer higher efficiency than standard induction motors used in the industry today, especially for small motor sizes. The increase in efficiency results in lower environmental impact and reduced electricity cost. The LSPMSM has, however, several drawbacks, among the most important is the reduced starting capability compared to induction motors. Furthermore, the rotor construction is complex and the added cost of magnet material makes the LSPMSM a comparably expensive motor type. The design of a LSPMSM is a trade-off between starting capability and steady state performance. The thesis discusses these trade-offs and the models that can be used as a basis for design and optimization. The models make use of different motor parameters, and a number of measurement methods for measuring these parameters are described and compared. Among these is a step response adapted measurement method that provides most of the parameters of interest. The development and setup of a brake bench for measuring both start-up and steady state performance is presented. Furthermore the start-up behavior and steady-state performance is calculated using measured parameters. The calculated performance is compared to measured performance and found to correlate well for nominal operating conditions. Thus, design guidelines can be based on the models proposed.</p>

USF completed a research study in 2005, which prioritized the replacement of 85 deteriorating composite precast deck panel bridges. This thesis re-evaluates the original recommendations in the wake of failures of two of these bridges in 2007. Since funding will not allow all identified bridges to be replaced, it was necessary to determine the most effective repair methods. To assess USF’s recommendations, a forensic study was undertaken in which the most current inspection and work program documents on the two failed bridges were reviewed and FDOT personnel interviewed. The best repair procedures were determined by reviewing repair plans, specifications, reports and site visits. The study found the two bridges that failed had been correctly prioritized by USF (No. 1 of 18 and No. 8 of 15). A new, accelerated repair method encompassing complete bay replacement was developed in a pilot project funded by the Florida Department of Transportation.
