Elitlicens infördes för klubbar i hockeyallsvenskan och elitserien i ishockey i början av 2000- talet. Elitlicensen ställer krav på idrottsklubbar, inte bara rent sportsligt utan även på det ekonomiska planet. Trots denna elitlicens uppmärksammas det fortfarande att ishockeylag åker ur hockeyallsvenskan på grund av ekonomiska problem. Dryga tio år efter införandet av elitlicensen ställer vi oss frågan om elitlicensen fungerar på ett tillfredsställande sätt. Syftet med vår studie är att söka svar på huruvida elitlicensen är effektiv som reglering, vi ställer oss frågan om elitlicensen är rätt sätt att reglera och om det därmed är rätt sätt på vilket man vill uppnå syftet med elitlicensen, att skapa stabilitet i serien. Med stabilitet i serien menar vi att klubbar inte får ekonomiska problem under säsongens gång och därmed blir tvungna att lämna pågående serie. Studien bygger på en kvalitativ analys där vi har genomfört intervjuer med representanter från svenska ishockeyklubbar i allsvenskan. Vår undersökning visar att elitlicensen, utifrån vår valda teoretiska referensram, till större del är en effektiv reglering. Studien visar att elitlicensen fungerar tillfredsställande på förebyggande plan men även att elitlicensnämndens roll är viktig för att elitlicensen som reglering skall vara effektiv.

For the application of 802.11a wireless communication system, this thesis aims to develop a novel suspending antenna with periodic structures to reduce electromagnetic wave from substrate using electrochemical deposition, surface micromachining and bulk micromachining technologies. This research presents two particular structures to increase the bandwidth and the radiation efficient and to reduce the return loss of the antenna, including: (i) the optimum design of periodic structures to restrain electromagnetic wave from substrate and to reduce the return loss of the antenna. To reduce the effective dielectric constant of the silicon substrate and to increase the bandwidth of the antenna, anisotropic etching the backside of the silicon substrate formed regular cavities using bulk-micromachining technology, (ii) to utilize a suspending structure to reduce the power loss through the substrate and to confirm the result using high frequency simulator. The implemented Si-based suspending antenna with periodic structures were characterized by a commercial network analyzer under 1~8 GHz testing frequency range. All the bandwidth and the return loss of the antenna proposed in this thesis are extracted by the commercial simulation software. Based on the measurement results, the center frequency is equal to 4.85 GHz, the return loss is around -35.5 dB and the bandwidth is equal to 42.9% (3.75~5.8 GHz). Eventually, this thesis successfully develops a low-loss and broadband antenna with novel structures using high frequency simulator and MEMS technologies for 802.11a wireless communication system.

Multimedia applications in wireless communication have shown notable increases over recent years. Specifically, Quality of Service (QoS) has become an important support mechanism in the context of a variety of applications which utilize network resources. The IEEE 802.16 standard for Wireless Metropolitan Area Networks (WirelessMAN) provides a complete QoS control structure designed to enable flow isolation and service differentiation over the common wireless interface. Although the media access control (MAC) mechanisms defined in this standard can offer predefined QoS provisioning on a pre-connection basis (additionally, many algorithms have been addressed to support QoS guarantees for various kinds of applications), the design for a stable, efficient and flexible MAC scheduling algorithm for such QoS provisioning still remains to be discovered. In this paper, we propose a QoS control scheme, Efficient Bandwidth Allocation (EBA), for the WirelessMAN system. Notably, this schedule enables predefined service parameters to control the service provided for each uplink connection and it provides each connection with different service opportunities such that the BS could allocate the most suitable bandwidth constantly for each connection with the various QoS parameters. Moreover, through MAC layer resource allocation, the proposed algorithm is capable of providing QoS guarantee for the SSs under different distance.

A local reconfiguration algorithm (INP) for reliable routing in wireless sensor networks that consist of many static (fixed) energy-constrained nodes is introduced in the dissertation. For routing around crash fault nodes, a communication tree structure connecting sensor nodes to the base station (sink or root) is dynamically reconfigured during information dissemination. Unlike other location based routing approaches, INP does not take any support from a high costing system that gives position information such as GPS. For reconfigurations, INP uses only local relational information in the tree structure among nearby nodes by collaboration between the nodes that does not need global maintenance, so that INP is energy efficient and it scales to large sensor networks. The performance of the algorithm is compared to the single path with repair routing scheme (SWR) that uses a global metric and the modified GRAdient broadcast scheme (GRAB-F) that uses interleaving multiple paths by computation and by simulations. The comparisons demonstrate that using local relative information is mostly enough for reconfigurations, and it consumes less energy and mostly better delivery rates than other algorithms especially in dense environments. For the control observer to know the network health status, two new diagnosis algorithms (Repre and Local) that deal with crash faults for wireless sensor networks are also introduced in the dissertation. The control observer knows not only the static faults found by periodic testing but also the dynamic faults found by a path reconfiguration algorithm like INP that is invoked from evidence during information dissemination. With based on this information, the control observer properly treats the network without lateness. Local algorithm is introduced for providing scalability to reduce communication energy consumption when the network size grows. The performance of these algorithms is computationally compared with other crash faults identification algorithm (WSNDiag). The comparisons demonstrate that maintaining the communication tree with local reconfigurations in Repre and Local needs less energy than making a tree per each diagnosis procedure in WSNDiag. They also demonstrate that providing scalability in Local needs less energy than other approaches.

Following Chang, Lai, and Chang(1999), this report discusses the policy assignment problem with efficient wage-employment bargaining under perfect capital mobility. Whether it can rescue the default of proposed by Ramirez (1988) that coordinate between fiscal and exchange rate policies to achieve given desirable targets. The conclusion of this report is as follows¡G Under fixed exchange rates with perfect capital mobility, however, an appropriate mixture between monetary and fiscal policies can dynamically adjust to attain simultaneously the internal goal of desired output and the external goal of official foreign reserves. It's conclusion as the same as proposed by Lai, Chang, and Chu (1990). But more importantly, it can rescue the default of proposed by Ramirez (1988) that coordinate between fiscal and exchange rate policies to achieve given the internal and external goals. Accordingly, we can understand that efficient wage-employment bargaining in the labor market plays a curial role in assessing the assignment or policy instrument to targets. Furthmore, this report extends the analysis results under fixed exchange rates shifting to the system of a managed floating regime. It can find that the policy assignment can still achieve given desirable target. Consequently, this report provides further evidence that the efficient wage-employment bargaining is very important for assignment problem.

ABSTRACT After the national universities in Taiwan implementing the college affairs funds, the expenditure comes from not only the government supply but also universities themselves. It¡¦s for the purpose of their needs on teaching, researching, and serving. In order to enhance the elasticity that the funds use independently and the competitiveness of higher education, it is bound to put more focus on both the managing and cost efficiency. This research adopts the efficiency-measuring mode of Data Envelopment Analysis (DEA) to weigh the conditions of managing results and efficiency fluctuations¡]the fluctuation of Malmquist productivity¡^of 51 national universities in Taiwan from year 2001 to 2004. The conclusion of obtaining is as follows: From the aspect of managing efficiency, National Chiao Tung University and National Dong Hwa University perform the best among the general universities; as for the technological universities and vocational colleges, National Taiwan University of Science and Technology and National Chin-Yi Institute of Technology perform the best. The lacks of valid managements in resource usages causes the technical inefficiencies; the general universities performed like the technological and vocational colleges were rather similar and relatively inefficient from the year 2001 to 2004. The reasons of inefficiency came from the technological efficiency of bad management with reached the scale efficiency of the best scale at the same time. The Malmquist indices of National Tsing Hua University and National Taichung University were more than 1 from the year 2001 to 2004; as for the technological and vocational colleges, the Malmquist indices of National Tai-Chung Institute of Technology, National Taichung Nursing College, National Taiwan Junior College of Performing Arts, and National Tainan Institute of Nursing were more than 1 as well. There is a decline trend gradually of productivity in 2001-2004 in both the general universities and technological and vocational colleges, it was mainly that the production technology efficiency retrogresses. Finally, implementing college affair funds may be still affected by other external objective environments, the one of great impact among them: external parameters, such as size of the school, the history of the school, and the location of the school. Through the regression analysis, there are strong correlation between campus size and management efficiency for the general universities; however, not between history and location of the school. On the other hand, the technological and vocational colleges, do not have dominance to whole efficiency value. From the analysis, we can understand the over-all performing, efficiency of the universities in Taiwan. The fund governors should manage and advent different efficiencies with various methods in order to promote the managing efficiency of the whole.

This dissertation presents a hybrid quadrature polar modulator (HQPM) to drive the power amplifier (PA) highly efficiently in a wireless RF transmitter with good potential for multi-mode operation. For enhancing the efficiency, a Class-E PA is used in the transmitter. The HQPM consists of a quadrature modulator for processing the RF modulated carrier and a Class-S modulator for processing the supply-voltage signal. The quadrature modulator and the Class-S modulator deliver the output signals with envelope variation before being inserted into the RF-input terminal and the supply-voltage terminal of Class-E PA, respectively, causing the double envelope modulation to distort the modulated RF signal at the PA output. Therefore, a digital predistorter is proposed to be embedded in the HQPM for compensation. The use of such predistorted HQPM techniques can help reducing the average DC and RF input powers and the output feed-through levels so as to enhance power added efficiency and adjacent channel power rejection quite remarkably.

Energy-efficient building design involves minimizing the energy use and optimizing the performance of individual systems and components of the building. The benefits of energyefficient design, in the residential sector, are direct and tangible, provided that design strategies with a substantial combined energy and cost-saving potential are adopted. Many studies have been performed to evaluate the energy-saving potential and the costeffectiveness of various design options, and to identify conditions for optimizing the performance of building systems and components. The results of these studies, published in various resources, were analyzed discretely using different techniques, and were reported using different bases for comparison. Considering the complex interaction of, and energy flows through various building components, it is difficult to directly compare/combine the results from various studies to determine the energy-saving potential of combination of strategies, and to select an appropriate set of strategies for making design decisions. Therefore, this thesis develops a comprehensive survey and analysis of energy-efficient design strategies and their energy-saving potential, in isolation as well as in combination, using a DOE-2 simulation model of a prototype house in the hot and humid climate of Houston, Texas. Optimized strategies that included building configuration, materials/ assembly for building envelop components, and efficient mechanical and electrical systems, equipment and appliances, were applied in combination that could minimize the annual energy use. Application of these strategies is expected to allow downsizing systems and equipment and to confirm their operation at their rated performance, resulting in additional installation and operation cost savings. The study is concluded by outlining the procedures for selecting optimized set of strategies, and by developing guidelines for achieving maximum energy-efficiency in singlefamily detached houses in hot and humid climates. Thus, this study will facilitate the selection of energy-saving measures for their individual or combined application for developing energyefficient residences in hot and humid climates.
