In this thesis, we propose two genetic-programming-based models that improve the trading strategies for mutual funds. These two models can help investors get returns and reduce risks. The first model increases the return by selecting funds with high Sortino ratios and allocates the capital equally, achieving the best annualized return. The second model also selects funds with high Sortino ratios, but reduces the risk by allocating the capital with the mean variance model. Most importantly, our model utilizes the genetic programming to generate feasible trading strategies to gain return, which is suitable for the market that changes anytime. To verify our models, we simulate the investment for mutual funds from January 1999 to December 2009 (11 years in total). The experimental results show that our first model can gain return from 2004/1/1 to 2008/12/31, achieving the best annualized return 9.11%, which is better than the annualized return 6.89% of previous approaches. In addition, our second model with smaller downside volatility can achieve almost the same return as previous results.

Sharpe ratio is extensively used in performance of portfolio. However, it is based on assumption that return follows normal distribution. In other words, when return in asset is not normal distribution, the Sharpe ratio is not meaningful. This research focuses on Generalized Sharpe ratio with different distribution in eight indexes from 2001/12/31 to 2010/12/31. We try to find a suitable levy process to fit our data. Instead of Normal distribution assumption, we use Jump diffusion, Variance Gamma, Normal Inverse Gaussian, Hyperbolic, Generalized Hyperbolic, as our distribution to solve stylized fact like skewness and kurtosis. Compared the difference between standard Sharpe ratio and Generalized Sharpe ratio, we come to these conclusions: first of all, Generalized Hyperbolic is better levy process to fit our eight indexes. Second, Sharpe ratio under GH levy process has low autocorrelation, and it present that modified Sharpe ratio is more elastic. Third, Generalized Sharpe ratio can uncover the strategy that fund manager manipulate Sharpe ratio. At last, Generalized Sharpe ratio have better predict than standard Sharpe ratio.

In this thesis we propose a robust PID controller to regulate the hydrogen flow of proton exchange membrane fuel cells. The controller allows the so-called hydrogen excess ratio to track a desired value rapidly in order to achieve saving hydrogen and to avoid damage of the fuel cell when the power output of the fuel cell varies from one level to another. The fuel cell system is governed by a set of complicated nonlinear dynamical equations. To ease the control design task, we model the system, at each operating point, as a feedback interconnection of a linear time-invariant nominal part with a norm-bounded perturbation. We use the technique of system identification to acquire the transfer function representation of the nominal part and the size of the perturbation. To do this, the chirp signal is adopted to excite the system and the observed response is analyzed using spectral analysis to obtain the model. Based on the model, a $H_{infty}$ PID controller is designed for the fuel cell system. The design is tested on an experimental platform. The experimental results verify that the proposed controller can regulate the hydrogen excess ratio rapidly under load variation, and effectively reject the influence of external disturbances.

In this thesis, we investigate the problem of channel estimation in the amplify-and-forward cooperative communication systems when the networks could be in the presence of selfish relays. The information received at the destination will be detected and then used to estimate the channel. In previous studies, the relays will deliver the information under the prerequisite for cooperation and the destination can receive the information sent from the source without any possible selfish relay. Therefore, the channel will be estimated under this over idealistic assumption. Unfortunately, the assumption does not make sense in real applications. Currently, we don¡¦t have a mechanism to guarantee the relays will always be cooperative. The performance of channel estimation will be significantly degraded when the selfish relays present in the network. Therefore, this thesis considers an amplify-and-forward cooperative communication system with direct transmission and proposes a detection mechanism to overcome the misbehaving relay problem. The detection mechanism employed estimation is based on likelihood ratio test using both direct transmission and relayed information. The detection result will then be used to reconstruct the codeword used for estimating product channel gain of the source-to-relay and relay- to-destination links. The mathematical derivation for the considered problem is developed and numerical simulations for illustration is also carried out in the thesis. The numerical simulation results verify that the proposed method is indeed able to achieve robust channel estimation.

The study use preparing the 2011¡¦s pro forma financial statements of China Construction Bank (CCB) at first, and use market stock price as given result, conjecture the Non-Performance Loan ratio of the market investors. And then, using implied Non-Performance Loan ratio, adjust the original financial statements, prepare the 2012¡¦s pro forma financial statements of CCB. In the end, using Copeland, Koller, and Murrin¡]2000¡^¡¦s equity DCF method and Preinreivh¡BEdwards and Bell¡BOhlson¡¦s EBO method to estimate the intrinsic value of the common stock for the China Construction Bank. Based on my analysis, it is suggested that, after preparing the pro forma financial statements by carefully considering economic environment¡Blaws and regulations¡Bindustrial structure and lending proportion¡Bmarket position, and future strategies of the specific bank, use two valuation model by considering implied Non-Performance Loan ratio. The intrinsic value of the common stock is higher than its market price, that is, the market price of the China Construction Bank is undervalued. Therefore, I hope the result of this business evaluation research, will help the investors making more rational decisions.

Abstract Banking industry which contributes significant annual economic growth rate is one of the most important industries in Taiwan. Since the trend that many countries give up the cash-based monetary system, the financial environment grows toward liberalization and globalization. Banking industry has shown more and more influence on the stability of economy. The financial Commissioner of MOU which signed on November 16, 2009 and effected on January 16, 2010 has taken the financial cooperation between Taiwan and China to a new stage. Under the framework of the Economic Cooperation Framework Agreement (ECFA), Mainland China will become an important part of Taiwan banking industry¡¦s future global distribution. With the impact of global financial tsunami and European sovereign debt crisis, the overall economic environment of Taiwan banking industry has been more difficult. On the other side, the number of competitor of the same nature increases since 16 new banks are approved to be set up from 1991 to 1992. According to the statistic of Financial Supervisory Commission, Executive Yuan, there is a total of 38 domestic banks with 3,398 branches and a total of 28 foreign banks with 53 branches over Taiwan. The business volume and profitability of traditional banks has been reduced, and wallet share ratio has been declined too. Thus, it is a must that bank adjust their traditional role from borrowing funds to a assist of asset management as quickly as possible to support customers a omni-bearing service provider. After the implement of Financial Holding Company Act in July 2001, the financial legislation has been lifted. It allow not only the establishment of financial holding companies but also the cross-industry operation of banking, insurance, securities, venture capital, investment trust business that providing customers on stop shopping service. Moreover, based on the principle of equity, the financial authority allow non-financial holding companies including banking, insurance, securities could development cross-industry service. Thus, non-financial holding companies should review their future development strategies and opportunities. The study is based on the simplified financial and insurance market structure which includes a bank and three insurance companies. When a individual bank cooperates with certain insurance company, there are two cooperation models¡Xthe establishment of financial holding company and cross-industry strategic alliance. The establishment of financial holding company adopts ¡§joint marketing¡¨ mode which vertical and horizontal integrates the flow of business, cash, logistic, information and talent to create a synergy of business profit. However, if there are differences of business culture and philosophy, the benefit may not be shown and may even adversely affect the alliance. The strength of ¡§strategic alliance¡¨ lies in the flexibility of operation of business and organization. With the cross-industry operation mode, managers could develop business strategy according to the difference structure and property thus not only retains original business idea and thinking but also capture unique niche of cross-industry then achieve the goal progressively. Through literature review and analysis of banking and insurance strategies, the study develops the research framework, questionnaire and dimensions in the background and motivation of cross-industry alliance, the condition and term of alliance partner selection strategy and interactive communication in the process of strategic alliance and cooperation to discuss the factors that influence the channel strategies of bank-insurance companies and the critical factors that make successful business expansion. The study hope to provide a reference for future development of bank ¡Vinsurance business to enhance the competitiveness of bank insurance industry in Taiwan.

Reducers are commonly used in many types of machines to reduce the speed and increase the torque of motors. For general industrial applications, the reduction ratio of a reducer is usually limited in consideration to its size. To provide high reduction ratios, harmonic drives (speed reducers) can be made very compact and lightweight and thus have been popular with robot manufactures and in other applications where weight is critical. In this study, an innovative design for reducers composed of planar cams and roller followers with high reduction ratios is proposed. It uses the relative motion between rollers and their cams to generate a high reduction ratio. In this thesis, the synthesis procedure of the reducer and the analysis results of the kinematic and dynamic characteristics based on the design parameters are also described. Furthermore, the experiments for testing and verifying the characteristics of the reducer are presented. Finally, a set of design parameters which meets the demand of an application is found by optimization methods.

Much of the current research in magnetic resonance engineering focuses on reducing the acquisition time for obtaining an image while simultaneously maximizing the Signal to Noise ratio (SNR) of the image. It is known that improvement in imaging time or resolution is obtained at the cost of SNR. Therefore wherever possible, RF coil engineers design the coil in such a manner so as to maximize SNR for that coil design. In one such design consideration, most coil designers prefer placing low impedance preamplifiers near the coil. The further the pre-amplifiers are from the coil, the greater will be the signal loss due to transmission and higher will be its input impedance as perceived at the coil which would degrade inter-coil isolation. Owing to the current trend of using increasing number of receiver channels (32, 64 or 128) for parallel imaging, placing the preamplifiers near the coil would greatly complicate the coil construction. The primary objective of this research was to find the relation between SNR and referred preamp impedance and whether preamps need to be placed on the coil, or if they can be placed outside the magnet at the end of a transmission line which would simplify the construction of large count array. In addition, SNR was studied as a function of coil design parameters - coil loading, array coil separation, and system frequency. Both theoretical and experimental methods were used to undertake this investigation. A popular electromagnetic modeling technique, finite difference time domain (FDTD), was used to model SNR in arrays of two 3 inch loop coils at 3T and 1.5T. Results were also verified through bench measurement at 3T and 1.5T and by evaluating SNR. To verify the robustness of our results and to assess the possibility of using low cost standard 50 ohm preamps, we carried out additional bench measurements at 4.7T. Results demonstrated that preamplifier placement is critical at low field strength. At higher field strength, SNR degradation due to preamplifier placement was less owing to heavier coil loading.
