Nowadays, the trend of maximizing the liquid crystal display panels makes the display firms and the upper suppliers hold the passive and disadvantaged position in Taiwan TFT-LCD industry, and cannot but push them follow Korea¡¦s strategies to set up new plants and promote the yield continuously. However, setting up a new plant indeed costs a lot, thus, how to reduce the total cost of the supply chain becomes an urgent key point in TFT-LCD industry. Therefore, the co-operative relationship between the upper key component firms and the middle panel firms, the complementary and complete extend of the materials, equipment and the key components can be highly home-manufactured or not, becomes the most important subjects. For this reason, how to help Taiwan¡¦s TFT-LCD industry acquire the active and predominant position is worth studying. The major TFT-LCD suppliers of technology and equipment in Taiwan still have to depend on Japan. Thus, this research intends to focuses on the large-size TFT-LCD firms and analyzes the present situation with the following three dimensions: 1. Can Taiwanese firms gain the active and dominant position with continuously building up plants and complete localized supply chain in TFT-LCD industry? 2. Discuss the level of completeness between the TFT-LCD panel firms and the upper key components firms with equipment and materials to survey that TFT-LCD industry is self-contained or not in Taiwan. 3. How to speed up the whole supply chain of TFT-LCD industry and makes it come into being. Eventually, this research results in three findings of TFT-LCD industry: 1.Crystal cycles happen repeatedly, and it not only fluctuates obviously but shorten the circular interval as well. 2. The technologies of TFT-LCD alternate rapidly. 3. The supply chain of Taiwanese TFT-LCD industry is not self-contained enough. In addition, the integrated and localized ability is over-slack. In conclusion, I take one foreign and one domestic industry-upgraded cases for examples, and try to figure out the constructive and positive guiding principle for the TFT-LCD industry and the following studies in the future. Key words: TFT-LCD, key components, supply chain.

In order to adapt with the rapidly changing industrial environment and improve the efficiency of management, enterprise needs to re-engineer their information system. The whole process of business reengineering is induced by motivation of reengineering. After that, enterprise needs to select a reengineering strategy and transform into the executive plan to start the rest part. The information system reengineering process follows the same pathway as process of business reengineering. The wrong strategy might lead the wrong execution, which cause failure of the whole reengineering. In this research, author tried to build a model to explain how reengineering motivation interacts with the choice of reengineering strategy, and verifies the model by real case chosen from Passive Component Electronic Industry. The outcome might be helpful for the enterprises whose information system reengineering is going to take place.

To have a voice link with other diving partners or surface personnel, divers need to put on a communication mask. The second stage regulator or mouthpiece is equipped with a circuit to pick up the voice of the diver. Then the voice is frequency-modulates into ultrasonic signal to be transmitted into water. A receiver on the other side picks up the ultrasonic signal and demodulates it back to voice, and plays back in diver's earphone set. This technology is mature but not widely adopted for its price. Most divers still use their favorite way to communicate with each other, i.e. DSL (divers' sign language.) As more and more intelligent machines or robots are built to help divers for their underwater task, divers not only need to exchange messages with their human partners but also machines. However, it seems that there are not many input devices available other than push buttons or joysticks. We know that divers¡¦hands are always busy with holding tools or gauges. Additional input devices will further complicate their movement, also distract their attention for safety measures. With this consideration, this paper intends to develop an algorithm to read the DSL as input commands for computer-aided diving system. To simplify the image processing part of the problem, we attach an LED at the tip of each finger. The gesture or the hand sign is then captured by a CCD camera. After thresholding, there will only five or less than five bright spots left in the image. The remaining part of the task is to design a classifier that can identify if the unknown sign is one from the pool. Furthermore, a constraint imposed is that the algorithm should work without knowing all of the signs in advance. This is an analogy to that human can recognize a face is someone known seen before or a stranger. We modify the concept of eigenfaces developed by Turk and Pentland into eigenhands. The idea is to choose geometrical properties of the bright spots (finger tips), like distance from fingertips to the centroid or the total area of the polygon with fingertips as its vertices as the features of the corresponding hand sign. All these features are quantitative, so we can put several features together to construct a vector to represent a specific hand sign. These vectors are treated as the raw data of the hand signs, and an essential subset or subspace can be spanned by the eigen vectors of the first few large corresponding values. It is less than the total number of hand signed involved. The projection of the raw vector along these eigen vectors are called the principal components of the hand sign. Principal components are abstract but they can serve as keys to match the candidate from a larger pool. With these types of simple geometrical features, the success rate of cross identification among 30 different subjects' 16 gestures varies to 91.04% .

As is known to all, Yageo plays a decisive role in passive component industry in the world. In 1991, Yageo¡¦s capital was only estimated NT$ 400 million. A series of acquisitions of not more than 10 years, Yageo¡¦s capital has reached NT$ 14 billion. It grows more than 30 times. Thereinto, the most famous and controversial issue was Yageo¡¦s ??650 million (Around NT$ 18.8 billion) acquisition of the passive component division of Philips in 2000. At that time, Walsin Technology quoted 8 billion. Why were the value evaluations of acquiring the passive component division of Philips on the 2 leading companies of passive components diametrically opposed? This study aims at exploring the effectiveness of this acquisition case at high price. In the early stages of Taiwan's passive component industry, Taiwan fell behind Japan, Europe and America in technology. In order to catch up with advanced foreign technology expeditiously, expand the market share, and become a global leading company from local Taiwan, acquisition and strategy alliance are very common method strategically. Nevertheless, through many literatures, we find that actually successful examples of acquisition are not many. Specially, Yageo¡¦s acquisition of the passive component division of Philips is that big beats small. Furthermore, transnational acquisition involves with different business philosophy, management system and corporate culture. Success of acquisition becomes more difficult. In terms of corporate managers, the most important responsibilities are to lead the company's growth, enhance shareholder value, bring prosperity to the community and provide more opportunities for employment and entrepreneurship. This case was studied from pre-acquisition in 1997 to post-acquisition in 2004 on each indicator for analysis and comparison to explore the gains and losses of whole acquisition. When enterprises are in the process of development, acquisition is absolutely one of the strategy options. However, how does acquisition strategy create the maximum value? The wisdom and decision of enterprisers will be strictly tested by market and investor. We hope it can provide usefulness for enterprisers in Taiwan to execute transnational acquisition by exploring this acquisition case.

<p>Component-based Software development is a promising way to improve quality, time to market and handle the increasing complexity of software management. However, The component-based development is still a process with many problems, it is not well de_ned either from theoretical or practical point of view. This thesis gives a brief overview of Component-Based Software development and starts with brief historical evolution followed by a general explanation of the method. A detailed discussion of the underlying principles like components, component framework and compent system architecture are then presented. Some real world component stadards such as .net framework, CORBA CCM and EJB are given in detail. Finally, simple fille-sharing-program based on Apache's Avalon framework and another one based on .net framework are developed as a case study.</p>

A biomechanical model of the human tongue was constructed, based upon a detailed anatomical study of an actual cadaver. Data from the Visible Human Project were segmented to create a volumetric representation of the tongue and its constituent muscles. The volumetric representation was converted to a smooth NURBS-bounded solid model--for compatibility with meshing algorithms--by lofting between splines, the vertices of which were defined by the coordinates of a smoothed triangular mesh representation. Using a hyperelastic constitutive model that allowed for the addition of active stress, the model deforms in response to user-specified muscle activation patterns. A series of meshes was created to perform a mesh validation study; in the validation tests performed, a 245,223-element mesh was found to be sufficient to model tongue behavior.Systematic samples of the behavior of the model were collected. Principal component analyses were performed on the samples to discover low-dimensional representations of tongue postures. Statistical models (linear regression models and neural networks) were fit to predict tongue posture from muscle activation, and vice versa. In all tests, it was found that a relatively small sample of tongue postures can be used to successfully generalize to larger data sets.Finally, a variety of specific tests were performed, based on claims and predictions found in previous literature. Of these, the claims of the muscular hydrostat theory of tongue movement were best supported. Simulations were also run that simulated lingual hemiplegia. It was found that substantially different muscular activation patterns were required to achieve equivalent postures in a hemiplegic tongue, relative to a normal tongue.

NonLinear Principal Component Analysis (NLPCA) using three-hidden-layer feed-forward neural networks can produce solutions that over-fit the data and are non-unique. These problems have been dealt with by subjective methods during the network training. This study shows that these problems are intrinsic due to the three-hidden-layer architecture. A simplified two-hidden-layer feed-forward neural network that has no encoding layer and no bottleneck and output biases is proposed. This new, compact NLPCA model alleviates these problems without employing the subjective methods and is called quasi-objective. The compact NLPCA is applied to the zonal winds observed at seven pressure levels between 10 and 70 hPa in the equatorial stratosphere to represent the Quasi-Biennial Oscillation (QBO) and investigate its variability and structure. The two nonlinear principal components of the dataset offer a clear picture of the QBO. In particular, their structure shows that the QBO phase consists of a predominant 28.4-month cycle that is modulated by an 11-year cycle and a longer-period cycle. The significant difference in variability of the winds between cold and warm seasons and the tendency for a seasonal synchronization of the QBO phases are well captured. The one-dimensional NLPCA approximation of the dataset provides a better representation of the QBO than the classical principal component analysis and a better description of the asymmetry of the QBO between westerly and easterly shear zones and between their transitions. The compact NLPCA is then applied to the Arctic Oscillation (AO) index and aforementioned zonal winds to investigate the relationship of the AO with the QBO. The NLPCA of the AO index and zonal-winds dataset shows clearly that, of covariation of the two oscillations, the phase defined by the two nonlinear principal components progresses with a predominant 28.4-month periodicity, plus the 11-year and longer-period modulations. Large positive values of the AO index occur when westerlies prevail near the middle and upper levels of the equatorial stratosphere. Large negative values of the AO index arise when easterlies occupy over half the layer of the equatorial stratosphere.
