We examine the electrochemical properties of SAM of alkanethiols terminated with biferrocenyl group (complex 7) to understand the interactions between metal surface and molecules. The cyclic voltammogram of complex 8 shows two successive reversible one-electron redox waves corresponding to the oxidation of the biferrocenyl moiety and all peak-to-peak separations are smaller than 59 mV (ideal value of one electron transfer with diffusing controlling). In addition, the peak currents are linear to scan rate, i.e., i£\V. This observation is corresponding to the electrochemical property of SAM, and we would like to suggest that the electron transfer process in the electrochemical measurements is direct controlling. Furthermore, we synthesized a nano-material by using of redox stable biferrocenylalkanethiol attached to gold cluster (complex 10). The clusters are stable in air, soluble in nonpolar organic solvents and the characters could be examining by traditional chemical instruments such as NMR, IR, UV/Vis, TEM. The cyclic voltammogram shows that the electron transfer process in the electrochemical measurements is also direct controlling. Finally, the well-known mechanism of intramolecular electron transfer in mixed-valence biferroceniums and the stable biferrocene on Au (111) surface and on gold clusters let to the more advanced concept. We believe that the microstructure of biferrocene assembled on an electrode surface or on gold clusters might enable to carry out a particular function extraordinarily well, for example, optical switch.

The Internet is increasingly being used as basic infrastructure for a variety of services. A high-performance server system is the key to the success of all these Internet services. However, the explosive growth of Internet has resulted in heavy demands being placed on Internet servers and has raised great concerns in terms of performance, scalability and availability of the associated services. A monolithic server hosting a service is usually not sufficient to handle these challenges. Distributed server architecture, consisting of multiple heterogeneous computers that appears as a single high performance system, has proven a successful and cost effective alternative to meet these challenges. Consequently, more and more Internet service providers run their service on a cluster of servers, and this trend is accelerating. The distributed server architecture is only an insufficient answer to the challenges faced by Internet service providers today. This thesis presents an integrated system for supporting scalable and highly reliable Internet services on the distributed server architecture. This system is composed consists of two major parts: Server Load Balancer and Distributed Server management System. The server load balancer can intelligently route the incoming requests to the appropriate server node. The Java-based management system can relieve administrator¡¥s burden on managing such a distributed server system. With these mechanisms, we can provide an integrated system to consolidate a group of heterogeneous computers to be a powerful, adaptive, reliable Internet server system.

We described the synthesis of multilayer organic thin films prepared by sequential vapor-phase coupling of monomers. The reactions were carried out at room temperature and atmospheric pressure. Films prepared using up to six sequential coupling reactions are reported. Homobifunctionalized monomers, such as hexamethylenediamine, react primarily via a single endgroup rather than cross coupling to the reactive surface via both reactive groups. We synthesized bifunctionalized polyamidoamine (PAMAM) dendrimers having both quaternary ammonium groups and primary amines on their periphery were prepared. The high positive charge on the surface of these dendrimers prevents agglomeration, and the unquanternized amine groups provide a reactive handle for immobilizing the dendrimer-encapsulated nanoparticles onto surfaces. We prepared highly monodisperse, 1-2 nm diameter Au nanoparticles using bifunctionalized PAMAM dendrimers as templates. The synthesis is carried out in water, takes less than 30 min, and requires no subsequent purification. The high monodispersity is a function of the template synthesis, which avoids size variations arising from random nucleation and growth phenomena, and the use of magic number equivalent ratios of AuCl4-/dendrimer. We investigated the electrochemical properties of Au, Pd and PdAu monolayer-protected clusters (MPCs), prepared by dendrimer-templating and subsequent extraction, are described. Purification of the extracted Au, Pd and PdAu nanoparticles was not required to obtain well-defined differential pulse voltammetry peaks arising from quantized double-layer charging. The calculated sizes of the nanoparticles were essentially identical to those determined from the electrochemical data. The capacitance of the particles was independent of the composition of core metal.

Taiwan¡¦s yacht manufacturing driven by overseas buyers has brought Kaohsiung so far from the local, but so close to the world, in a unique relation between the global production networks (GPN) and the local cluster. In accordance with the commodity flow in the economic geography, it formulates the embeddedness within the yacht cluster, connects to the global market, in terms of recognition of ¡§yacht culture¡¨. The method applied in the study is one-to-one interview. The interview records are to be validated by cross-checking with the publicised written documents, and personal experience to the UK boat shows. Firstly, the specialised cluster of Kaohsiung yacht industry is analysed by members, organisations and business trends. Then, the yacht market is explained globally, such as the characteristics of the transnational corporations (TNCs), the commodity chains, and especially, the dealers/brokers, who act as key controller at the sales channel. In addition, the recognition on yacht industry invisibly dominates the aspects of manufacture and business nature, from local to global, which incubates its importance from yacht culture. Finally, the role played by the state for the past years, as supporter and destroyer, is to be evaluated accordingly. Is yacht implied simply as a product, or a life-style? In fact, Taiwan¡¦s yacht manufacturers grouped in a specialised cluster have been benefiting from job flexibility by producing quality items with fast income. However, the business model of Kaohsiung yacht cluster is to be reshaped, due to the demand of branding and creativity, reinforcement of market access, and inevitable global flows of manpower and resources.

Wireless sensor networks typically consist of a significant number of low-cost sensor nodes which can collaborate among each other to execute a wide range of applications, such as environmental and health monitoring, intrusion detection, etc. Basically, sensor nodes are mainly battery-powered and have a limited amount of energy to spend, thereby they are not likely to be recharged or replenished after being deployed in an inaccessible sensed environment. As a result, in the past decade, power saving has become a critical issue for the design of a media access control (MAC) protocol in wireless sensor networks. By incorporating power-saving mechanism into MAC, we expect to maximize the lifetime of a sensor network. Intuitively, a large amount of research tends to make use of the TDMA protocol because it has inherently more favorable characteristics when compared to the CSMA protocol, that is, sensor nodes only need to wake up to transmit or receive data at its allocated time slots, and other time slots they can go into sleep mode. By doing so, it can reduce power consumption. However, in this master thesis, we found that there exists a rather acute problem, called the Multiple-Cluster Collision (MCC) problem, in the TDMA cluster-based protocol that will degrade the system performance drastically. Therefore, in this thesis, we propose the approach, called Multiple Cluster Collision Problem (MCCP), to perfectly eliminate the MCC problem by sensor nodes. Finally, we will compare our approach with SRSA, proposed by Tao WU et al., to show that the performance of our approach outperforms SRSA in terms of collision reduction, throughput and so on.
