The recent advances in mobile computing and distributed multimedia systems allow mobile hosts (clients) to access wireless multimedia Data at anywhere and at anytime. In accessing multimedia information on the distributed multimedia servers from wireless personal communication service systems, a channel assignment problem and synchronization problems should be solved efficiently. Recent demand for mobile telephone service have been growing rapidly while the electro-magnetic spectrum of frequencies allocated for this purpose remain limited. Any solution to the channel assignment problem is subject to this limitation, as well as the interference constraint between adjacent channels in the spectrum. Channel allocation schemes provide a flexible and efficient access to bandwidth in wireless and mobile communication systems. In this dissertation, both an efficient distributed algorithm for dynamic channel allocation based upon mutual exclusion model, and an efficient distributed synchronization algorithm using Quasi-sink for wireless and mobile multimedia systems to ensure and facilitate mobile client access to multimedia objects are proposed. Algorithm's performance with several channel systems using different types of call arrival patterns is determined analytically. A set of simulation experiments to evaluate the performance of our scheme using message complexity and buffer usage at each frame arrival time.

With the development of the internet protocol (IP) and digitization for the global telecommunication industry, the convergence rate of communications and broadcasting has been improved. According to these motives, the domestic telecommunication industry modify present commercial operation managements and combine with the communication networks, the fixed-mobile communication (FMC) networks, and the mobile communication networks into the all-internet protocol (all-IP) communication network structure based on the extended upgrade communication network system. The domestic telecommunication industry expect that the integrated heterogeneous network, including the speech data, the video data, and the communication services, which can provide the omnipresent customizable mobile communication network services and obtain the advance business opportunities in terms of the future development of digital convergence. Hence, the domestic telecommunication industry not only build the next generation network structure to satisfy their demands, but also develop the management information system (MIS) to monitor the operation of telecommunication networks for ensure the quality of communication services and achieve the development of next generation networks. A primary consideration is to assure the usability of MIS for the telecommunication industry and the customers based on the profit rates and the omnipresent mobile network services, respectively¡C However, the current status of the telecommunication industry that meet the many difficult challenges and problems to construct the next generation MIS. For examples, the all-IP-based open network structure will be used instead of the close network structure, the different generation telecommunication systems combine with the operation and maintenance information system, the information security incident, and so on. It is must to consider highly of these situations between the major links above. Otherwise, the service usability of MIS will be destroyed. In this thesis, we adopt the case study approach to analyze the MIS construction process of the domestic telecommunication operator. During the build process, the MIS construction of next generation telecommunication networks must to suffice for the flexibility, the safety, and the stabilization and need to make sure the critical mission on stable operation condition, the lower service interruption, the higher usability. The implementation of the next generation MIS, which will help support the crucial operation procedure of the conglomerate and cope with the fast variation of the market demands.

The subject of diploma thesis is cycle of paintings, animation and video. This work is based on the operation system error. I focusing on well know phenomen of freezing computer and follow layering of system windows over themselves. Due to an error may arise aesthetic shape, which may refer to geometric abstraction. On this phenomenon interested me especially the elementary aspects of painting, building space on surface, geometry, movement and shape.

和顧客保持長期關係，對於企業經營是有利的，然而，由於資訊科技的進步與物流效率的提升，顧客越來越來越聰明，要尋找並取得替代產品與服務也越來越容易。在這樣的環境前提下，如何使顧客願意與企業維持長期關係而不轉向競爭者，是企業的一大挑戰。在文獻探討中本文發現，其關鍵是在於要能夠持續與顧客互動並了解顧客，並且將這些了解應用於產品設計、流程設計與組織設計。對於顧客的了解，本文定義其為顧客知識，就成為了顧客關係的基石。不過，由於與顧客的接觸點越多，了解顧客的管道就越多，其整合上有一定的難度，而資訊科技與傳統行銷方法都能夠產生對於顧客的了解，再加上產生並應用對於顧客的了解，以塑造顧客在消費與使用產品與服務時能得到高度的滿意，已經企業所有部門的責任，這樣跨部門的作業也不是一件簡單的事，這些議題都是企業在顧客知識管理上所需面對的。 在過往的文獻中所談的顧客知識管理，很多都混淆顧客資訊與知識，較無探討企業如何加工與顧客互動所得到的資訊，因此無法清楚了解企業在顧客知識管理上所作的貢獻為何。本文就以流程觀點，並以目前市場需求飽和且競爭激烈的人壽保險產業中的一家企業：保誠人壽為例，探討企業內的顧客知識流程，並且探討主要的影響因素，以了解企業在顧客知識管理上所作的努力。 而在本文個案的探訪後，本文還嘗試以服務業作業系統的角度，提出一種顧客知識的新分類：前台作業所需的顧客知識、後台作業所需的顧客知識，並且根據個案中保誠人壽的實際做法，修正文獻探討所提出的顧客知識管理架構，並且提出三種顧客知識管理的類型以及提出其管理重點，以作為實務界與後人研究的參考。 / It is beneficial for an enterprise to keep long-term relationship with its customers. However, owing to advances of information technology and the improvement of logistics efficiency, it is not difficult to search and acquire better products and services to substitute for what they are using now. Under these circumstances, it is a challenge for enterprises to retain their customers. How to do this? The answer in literatures is: to gain more customer insights (defined as customer knowledge in this study) through interactions with customers and apply them in product design, process design and organizational structure design. Therefore customer knowledge is the basics of long-term relationships with customers. But still, there are issues. First, an enterprise may have many contact points with its customers. Then, there are traditional ways versus information technology ways to generate customer knowledge. Finally, an enterprise has to think how to address appropriate customer knowledge to right departments and use them to enhance the total experience when interacting with customers. These are all issues an enterprise has to face with when trying to do “Customer Knowledge Management” (CKM). Most of past studies on CKM did not tell the difference between information and knowledge, thus can not clearly define what contributions an enterprise makes when implementing CKM. This study attempts to investigate practices of CKM in an enterprise in life insurance industry, in which the demand is saturated and the competition is fierce, from a process perspective to manifest how customer knowledge is generated and applied, and what main factors are to affect CKM in an enterprise. After investigation of the case, this study proposes a new framework, from the operation system in service industry, to classify customer knowledge into two categories: customer knowledge needed for front-office operations, and customer knowledge needed for back-office operations. In addition, according to practices in this case, this study will revise the CKM process framework proposed right after the literature review, and will raise keys to successful CKM in CKM processes, for the reference for following studies.

This thesis deals with the development problems and creating of the multi- purpose hardware platform, which supports operating system Linux. It is focused on the microprocessors using ARM architecture with architecture ARM7, ARM9 and ARM11. The scope of the first part of this thesis was searching the sales of available 32 bit ARM microprocessors. The second part is attended to a particular Mini2440 development kit, its animation and the subsequent development of the kernel drivers for OS Linux platform. One of this thesis details was also the development of my own expansive hardware module and a capacity keypad for a usage with Mini2440 developmental kit.
