Transparent thin film transistors fabricated at room temperature by radio frequency magnetron sputtering using indium oxide material system were proposed. The electrodes of the transparent thin film transistors were obtained by depositing indium oxide with 10% tim doping. Resistivity as low as 4¡Ñ10-4£[-cm at room temperature was achieved. The channel layers of the transparent thin film transistors were fabricated using pure indium oxide target in an Argon and oxygen environment. Resistivity larger than 10-5£[-cm was obtained with 60% oxygen partial pressure. Silicon nitride prepared by room temperature radio frequency sputtering were used for the gate dielectric layer with low leakage current. Environmental-safe lift-off processes were used to fabricated the electrodes, the isolation layer, and the channel layer. The transistor characteristics were obtained by standard I-V measurement. The on-off ratio of the 30£gm ¡Ñ 150£gm transparent thin film transistor is 100.

Level densities and spin cut-off factors have been investigated within the microscopic approach based on BCS Hamiltonian. In particular the spin cut-off parameters have been calculated at neutron binding energies over a large range of nuclear mass using the BCS theory. The results are compared with their corresponding macroscopic values. It is found that the values of spin cut-off parameter do not increase smoothly with A as expected based on macroscopic theory. Instead, the values of spin cut-off parameter show structures re&deg / ecting the angular momentum of the shell model orbitals near the Fermi energy. The spin cut-off parameter has also been computed from the knowl- edge of nuclear level density, at neutron binding energy, Bn and the average s-wave neutron spacing. The values of spin cut-off parameter are compared with their corresponding values from the model calculations. The in&deg / uence of the isospin in nuclear level density in particular the isospin cut-off parameter has also been investigated and are compared with their corre- sponding spin cut-off parameters.

Prior to concerns of sustainability, almost all industrial engineering models tried to minimize cost or maximize profit. Sustainability awareness has recently forced the decision makers to also take into consideration such aspects as clean water use, or carbon dioxide emissions. In an effort to incorporate more aspects of sustainability in optimizing production efforts, we present a network model to handle trade-offs among dissimilar sustainability criteria. Since typically there are alternative choices for the various operations, the network allows parallel arcs between the same nodes. We also introduce the concept of generalized cost. Generalized cost is a vector quantity that includes not only a monetary measure, but also measures relevant to sustainability, such as carbon use or embodied energy. The approach leads to a multi-criteria decision making model, whose efficient frontier is obtained by the epsilon constraint method. Numerical work shows that the computational effort to obtain the efficient frontier is reasonable, allowing products of up to about a hundred activities to be solved with the current generation of personal computers.

Aluminum nitride (AlN) thin films were deposited on SiO2/Si substrates using the reactive RF magnetron sputtering in this thesis. By means of the analysis of XRD, SEM, TEM and AFM, the optimal deposition conditions of highly C-axis oriented AlN films were obtained with RF power of 190W, sputtering pressure of 3mTorr, nitrogen concentration (N2/N2+Ar) of 30%, and substrate temperature of 400¢J. The characteristics of films annealed at temperature range from 600¢J to 1150¢J with N2 flow for 2 hours has been studied. Experimental results reveal that the films retain the high quality up to 800¢J. But when the temperature above 1000¢J, AlN films will be oxided to AlO:N. In addition, the interdigital transducers (IDTs) were fabricated on the films annealed at 800¢J for 2 hours to study the characteristics of SAW devices. The results show that the central frequency, insertion loss and phase velocity of SAW were 182.25 MHz, -12.95 dB and 5824 m/sec, respectively. At the same time, we try to match the impedence of devices and improve the frequency response by using a simulation program. After the impedence was matched, the insertion are not strongly improved but the frequency response and closed-in sidelobe rejection exhibit better. The effects of temperature on the SAW devices show that the central frequency almost does not shift when the temperature increases. But the insertion loss slightly increases with the temperature increased, the variation is about -0.02 dB/¢J.

Abstract The finance literature offers two major models about the capital structure of a firm. In the tradeoff model, firms tradeoff the costs and benefits of borrowing to identify their optimal capital structure and gradually move towards it. On the contrast, firms do not have an optimal capital structure in the pecking order model. The moving of the capital structure is simply the result of the financing hierarchy: retained earnings, safe debt, risky debt, and finally equity. The purpose of this study is to test whether the public firms in Taiwan have optimal capital structure. We address the question with cross-section regressions. If the tradeoff exists, moving towards the optimal capital structure will explain the change of capital structure. On the other hand ,the deficit-in funds¡]DEF¡^will explain the change of capital structure when the pecking order model exists. The empirical result shows that the public firms in Taiwan have optimal capital structure, and their realized capital structures are moving towards it, but the speed of adjustment is quite slow.

Abstract The ratio of unemployment in 2000 is 2.99%. The ratio of unemployment in 2001 is 4.57%. The ratio of unemployment in 2002 is 5.17%(narrow sense). The ratio of unemployment in 2002 is 7.26% (broad sense). They achieve the highest record in history at the same time. Mention as above we know unemployment has become the most serious problem in Taiwan now. The top three motorcycle companies in Taiwan are KYMCO, SYM, and YAMAHA which have different business styles, so there must be some differences in design and practice of downsizing programs. Finding the same points and the differences in downsizing programs are the motives of this research. And forming experience rules for business to use can show the value of this research. On the other side, we can find manpower market problems in manufacturing industries in Taiwan from researching Taiwan motorcycle industries. The quantities method researches about quitting are very popular recently. Although the research contents can provide many ideas for business, the business truly needs the know-how of planning in advance and implementing steps in downsizing programs that are key factors whether the downsizing programs can smoothly succeed or not. But we seldom read such descriptive researches that business readers really want to consult. This research tries to discuss with process design and tasks of every stages of downsizing programs according to time axis. Secondary data are from newspapers, periodical, thesis, books, company publication, and network. Primary data come from case companies interview (the first step) and questionnaire (the second step). The objects who this researcher interviews are HR department managers of KYMCO, SYM, and YAMAHA. The in-depth interview of the first step¡Gthis research analyzes the origin of downsizing programs from business condition, gets together the practice process and situation of downsizing programs from history vestige, records the improved activities after downsizing programs from holding the present situation, and describes business vision from future chance. The questionnaire of the second step¡Gtry to understand the feeling that personnel matters workers feel at heart in carrying out downsizing programs, the opinions that personnel matters workers think about downsizing programs, the belief that decision-making managers have to personnel matters workers¡¦ professional performance in downsizing programs. From the comparison and analyses of interview data of case companies, we can clearly know the cause, entire process, and effect of downsizing programs of the top three motorcycle companies in Taiwan. At last this research submits the related proposals from different views¡Gthe proposal for employees (create high additional value), the proposal for government (create occupation advantage by improving political and economical environment), the proposal for business (laws side. human kindness side. management side. implementation side ), the proposal for case companies (strategy. internation. system. science and technology).

The research takes depth interview of the case study method. It focuses on the engineering department of the telecommunications industry which is transformed into an independent engineering company by spin-off. It also discusses the motive of diversification and the model of operation. The research expects to understand the interactive relation between successful entrepreneur, management abilities and resource using. The research chooses a successful spin-off company as it's case study. It discusses the strategy phase and implementation phase to find out the key success factors. By analyzing the documents about entrepreneur, the research investigates the managements and strategies of spin-off and integrates the theories and practices into a conclusion: 1. Strategy is the motive power of entrepreneur: The right strategy is "Do the right thing". Whether a start-up can start or not depends on the right combination of core strategies, strategic resources and value net. 2. Implementation is the driving power of entrepreneur: The good implementation is "Do the thing right". Whether a strategy can operate or not depends on the efficient combination of organization structure, human resource, technical R&D, manufacturing, marketing, customer relationship and financial planning. 3. Key success factor (KSF) is the accelerating power of entrepreneur: Only if the strategy phase and implemetation phase operate in coordination, the start-up possesses the condition of success. However, just a fast success is a real success in the speedily changing time. A start-up company cannot shorten the time to success unless it owns some special KSF. 4. The success in the entrepreneurial phase can't ensure that the start-up will also succeed in the future operation. It must transform the success factors in the entrepreneurial phase into the ones in the future operation.

Marine energy is a renewable source that has not been exploited widely. Fetching the off-shore marine energy requires a lot of investments, thus, maximizing the power delivered by the marine current system is important. Marine current power generation may be limited during certain periods due to weather situation and far distance power transmission that makes failure rate arise and repair time long. In this thesis, using marine current speed recorded at Taiwan coastline, we analyze the reliability and not-delivery energy indices of different off-shore power collection topologies and transmission system by using fault tree analysis and network reduction method. Model parameter uncertainty effects on the system reliability are studied and economic assessments of these configurations are also conducted.

<p>Shaped charges are a well established type of projectile, subjected to a lot of research ever since emerging as a viable technology in the 1940s. The penetration achieved by shaped charges decreases with increased standoff distance. This is often attributed to the shaped charge jet losing its coherence. The Swedish Defence Research Agency however, noted no such loss of coherence in its experiments. An alternative explanation to the decrease of penetration was instead proposed. The object of this thesis was to investigate this proposed theory. To this end, the hydrocode Autodyn was used, modelling the impact of a high-velocity projectile into a generic target and analysing the resulting behaviour of the target. Several setups were used and several parameters were considered when evaluating the results. The conclusion of this thesis is that the alternative explanation offered is not supported by the observed behaviour of the target in the computer model.</p>
