There were three big oil crises in twenty century, and all made international political shakes. The global warming triggered the climate change, the rising of sea horizon and other environmental problems. The advanced countries begin to think about decreasing the dependency of fossil fuels as economic grows. Both the Kyoto Protocol in 1997 and the United Nations Copenhagen Climate Change Conference in 2009 were the evidences that most of the countries in the world are all concerned about climate change and economical environments. Furthermore, the Kyoto Protocol and the United Nations Climate Change Conferences affected the global economic policies, and also generated new ideas of green economy. Because of the impacts from the environmental and economic view, many countries made new green energy policies to develop renewable energy, promote green industry, wake up environment protection ideas, and broadcast the education of save energy saving and carbon reduction. This thesis uses the historical method, content analysis method and comparative method and the public policy theory as the theory basement. Then the thesis introduces the summary of global green energy industry. Taiwan and Singapore are called as Four Asian Little Dragons, but both lack of nature resources and depend on energy importation. The thesis discusses the policies on green industry of the Taiwan and Singapore, and also discusses the outputs of the policies. The final part is the policy comparisons between the two governments.

In this dissertation, we studied methods for improving efficiency and effectiveness of multipath routing in computer networks. We showed that multipath routing can improve network performance for failure recovery, load balancing, Quality of Service (QoS), and energy consumption. We presented a method for reducing the overhead of computing dynamic path metrics, one of the obstacles for implementing dynamic multipath routing in real world networks. In the first part, we proposed a method for building disjoint multipaths that could be used for local failure recovery as well as for multipath routing. Proactive failure recovery schemes have been recently proposed for continuous service of delay-sensitive applications during failure transients at the cost of extra infrastructural support in the form of routing table entries, extra addresses, etc. These extra infrastructure supports could be exploited to build alternative disjoint paths in those frameworks, while keeping the lengths of the alternative paths close to those of the primary paths. The evaluations showed that it was possible to extend the proactive failure recovery schemes to provide support for nearly-disjoint paths which could be employed in multipath routing for load balancing and QoS. In the second part, we proposed a method for reducing overhead of measuring dynamic link state information for multipath routing, specifically path delays used in Wardrop routing. Even when dynamic routing could be shown to offer convergence properties without oscillations, it has not been widely adopted. One of reasons was that the expected cost of keeping the link metrics updated at various nodes in the network. We proposed threshold-based updates to propagate the link state only when the currently measured link state differs from the last updated state consider- ably. Threshold-based updates were shown through analysis and simulations to offer bounded guarantees on path quality while significantly reducing the cost of propagating the dynamic link metric information. The simulation studies indicated that threshold based updates can reduce the number of link updates by up to 90-95% in some cases. In the third part, we proposed methods of using multipath routing for reducing energy consumption in computer networks. Two different approaches have been advocated earlier, from traffic engineering and topology control to hardware-based approaches. We proposed solutions at two different time scales. On a finer time granularity, we employed a method of forwarding through alternate paths to enable longer sleep schedules of links. The proposed schemes achieved more energy saving by increasing the usage of active links and the down time of sleeping links as well as avoiding too frequent link state changes. To the best of our knowledge, this was the first technique combining a routing scheme with hardware scheme to save energy consumption in networks. In our evaluation, alternative forwarding reduced energy consumption by 10% on top of a hardware-based sleeping scheme. On a longer time granularity, we proposed a technique that combined multipath routing with topology control. The proposed scheme achieved increased energy savings by maximizing the link utilization on a reduced topology where the number of active nodes and links are minimized. The proposed technique reduced energy consumption by an additional 17% over previous schemes with single/shortest path routing.

¡§The Financial Institution Merger Act¡¨ and ¡§Financial Holding Company Act¡¨ were legislated in 2000 and 2001 in Taiwan. Based on those Acts, there are 14 financial holding companies established till now . Except for Waterland Financial Holdings, the other 13 financial holding companies include banking industry business. It is obvious that the performance of bank does influence the performance of financial holding company. Bank joins in financial holding company hoping to provide ¡§one-stop shopping¡¨ diverse financial commodities to consumers through joint-marketing, sharing resources and equipment, and hoping to gain ¡§Cross Selling¡¨, ¡§Cost Savings¡¨ and ¡¨Capital Efficiency¡¨ performance¡]3C performance¡^. It expects to pursue broadly business scope and gain more profits through this business model. The research uses Mann-Whitney test of non-parametric statistics to examine the performance of the banking subsidiary of financial holding company in order to understand whether banks can gain expected efficiency after joining in financial holding company. The empirical results are listed as follow¡G First, the ¡§cross-selling¡¨ performance of the banks after joining in financial companies is better than those before joining in financial companies. While there are no significant differentials in ¡§cost-saving¡¨ and ¡§capital-efficiency¡¨ performance. Second, the ¡§profit ability¡¨ performance of the banks after joining in financial companies is better than those before joining in financial companies. Third, there are no significant differentials in growth ability between the banks after joining in financial companies and those before joining in financial companies. Fourth, the cross-selling performance and profit ability of the individual banks such as the Chinatrust Commercial Bank, Taishin International Bank, The International Commercial Bank of China, Cathay United Bank, Taipei Fubon Bank and E.Sun Bank after joining in financial companies is better than those before joining in financial companies. Fifth, the performance of ¡§cost-saving¡¨; ¡§profit ability¡¨; ¡§growth ability¡¨ and ¡§asset quality¡¨ of the banks affiliated to the financial holding companies is better than those not affiliated to the financial holding companies. Sixth, the overall performance of the banks affiliated to the financial holding companies is better than those not affiliated to the financial holding companies. But not all of the banks affiliated to the financial holding companies after joining in financial companies perform better than before. So the banks not affiliated to the financial holding companies can grasp their own niches and enforce core business. They can develop better than before even though their scale not big enough.

In this thesis, We propose two power saving strategy in wireless sensor networks with multi-packet reception and slotted ALOHA is as a systematic model. We concentrate on the case in which the packet arrival process is Bernoulli and the maximum queue is 1.This thesis first simulate results and to compare with the analytical results of pervious thesis. Traditional slotted ALOHA only have transmit and idle state. In this thesis, add a sleep state to decrease the energy consumption, and according to different strategy propose two different methods. This two methods decide to the sleep time and the retransmission probability to achieve the energy-efficient. At last we will use the simulation result to show the performance of our power saving strategy.

Fluidized bed combustion (FBC) ashes containing significant amount of free CaO and CaSO4 in addition to valuable inorganic acidic oxide ingredients such as SiO2, Fe2O3 and Al2O3 can be utilized as potential raw materials in the production of nonexpansive belite-rich calcium sulfoaluminate cement which is one of the special cement type of sulfoaluminate-belite cements having performance characteristics similar to those of ordinary portland cement besides lower energy requirements and CO2 emissions during manufacturing. Therefore, in this thesis study, possibility of producing non-expansive belite-rich calcium sulfoaluminate cement by adding FBC ashes in various proportions to the raw meal was investigated. For this purpose, a raw meal composed a mixture of limestone, bauxite, gypsum together with 10 wt % bottom ash and 15 wt % baghouse filter ash was prepared. It was sintered in a laboratory scale muffle furnace at temperatures of 1200, 1250 and 1300 &deg / C for various holding times. The results of chemical and mineralogical analysis as well as microscopic examination reveal that FBC ashes have the potential to be used in the raw meal due to the presence of characteristic mineral phases of this type of cements, i.e. yeelimite, larnite, ferrite and anhydrite, in the sample obtained at optimum sintering temperature of 1250 &deg / C for 60 min.

As a result of widespread and effective usage of internet, firms tend to collaborate to reduce their operating costs. This thesis analyzes collaboration opportunities for a group of small shippers. A transportation intermediary determining the optimal actions for arriving shippers and a mechanism allocating savings to the shippers is proposed in the thesis. The performance of the intermediary is assessed by using computational analyses. An experimental set is formed that is by changing the parameters that are expected to significantly affect the optimal policy structure and the surplus budget (or deficit) changes. It is seen that increasing variable costs like cross-assignment cost and waiting cost leads to the increase in comparative performance of the optimal policy compared to the na&iuml / ve policy, which is defined according to a simple rule, although increasing dispatching cost, which can be considered as a fixed cost, leads to an opposite result. The performance of the optimal policy is also assessed by using a myopic policy, in which shippers are trying to maximize their own benefit without considering the overall benefit of the grand coalition.

The energy service industry is a newly emerging industry in Taiwan, where related regulations and measures are still at an immature stage. The business operation models include being a motivator in regard to energy conservation, becoming an ESCO, or developing strategies covering both areas. The implementation will help present energy users to break through existing bottlenecks involving: funds, manpower, technology, and recycling term; change the environment where the Government is currently the main motivator; and attract private companies to participate in energy saving and carbon reduction. First, topics for in-depth interviews were established in order to obtain a better understanding of the operational environment of ESCOs in Taiwan, including any obstructions encountered during the development of the ESCO industry. Second, in-depth interviews were carried out with selected ESCOs via explorative research and quantitative methods. The interview data were analyzed and discussed. The following results were obtained regarding the domestic ESCO industry: 1. The status of current development and business opportunities is promising. 2. Factors affecting current development include the lack of regulations, subsidizing plans, third party authentication, energy-saving technologies, and financing solutions. 3. The financing difficulties include: insufficient collateral, sound financial reports, or banks¡¦ understanding of the ESCO industry. 4. The key success factors for the domestic ESCOs to enter the global ESCO market include: the accuracy of the energy-saving reports and income estimates, provision of integrated energy-saving technologies, and utilization of the small and medium business credit guarantee funds and loans. 5. Business models that best suit the development of domestic ESCOs include: sharing energy, performance guarantees, and equipment lease.
