The Digital Innovation of Appropriating Traditional Chinese Lyric Poems in Creative Design
Authors: Su Pei Hsuan
Published: March 2013

The research integrates digital editing system while making digital images for interpreting two traditional Chinese lyric poems written by Su Shi (1036-1101 A.D.) in Sung Dynasty. It serves as a digitalized visual language to recognize the Chinese literati aesthetics. The research approach is based on the use of semiotic analysis, in which the researcher emphasizes connections among viewers, content, and its cultural context. Instead of treating each component as a separate entity, the research seeks correspondences. The results suggest the use of visual and sound effects, lighting, color and motion of the digital-image design as possible underlying factors for the significant correlations found between personality traits and design preferences in practice, and should open an opportunity among the viewers to interpret the artworks in person. In addition, the study has to be recognized by its eastern and western viewers underlying a cross-cultural basis of interpretation. In conclusion, the research would make a contribution to explore new types of cognitive interpretation of Chinese lyric poems, and result in a complex interaction between vision and sound in creative design.

Published: March 2013

In this paper, the effect of environment and altitude on ultrahigh frequency (UHF) band has been studied. Both theoretical study and experimental investigations are conducted in order to model and characterize such complex communication medium. The experimental study is primarily aimed at critically analyzing the detrimental impact of channel condition on received power in hilly environment under different altitudes. The propagated signal strength varies from one place to another due to time varying channel condition as a result of obstacles between the transmitter and receiver. There is dramatic need to experimentally investigate such scenario in order to provide an avenue through which service providers can strategies their policies for effective wireless communication. Developing such channel models is extremely useful in communication systems design and simulation. The proposed model has been compared with ITU-R model for verification of the develop model for propagation loss prediction in hilly environment. The results obtained are compared with different measurement at various altitudes in hilly terrain environment.
An Integrated Model of Flexible Design Process for Taiwanese Housing Developments
Authors: Wen Kuo Hsun , Lam Artde D. Kin Tak
Published: March 2013

This paper proposes a human-centered design approach to provide a model of flexible design process for private housing development in Taiwan. By integrating concepts of “Open Building” and “Open Source Building”, this paper suggests the scope for the ongoing customization of individual units within housing developments that intends to facilitate real-world, sustainable development for the Taiwanese housing market. Also, it argues that the current market-led design approach creates inherent problems for the Taiwanese housing developments. However, in Taiwan’s housing sectors are coupled with entrenched, unsustainable decision-making from housing developers and particularly the intractable communication gap between developers, architects and homebuyers. The current circumstance is that architects often lack professional integrity and serve the interests of developers before those of home occupants as well as the wider community. Noticeably, growing global awareness of sustainable development has recast housing as an intrinsic component of the urban environment and successful communities. In Taiwan, short-term profitability rather than long-term sustainability drives private housing. As a result, by employing a series of exploration to current design process and the principle of design management, this paper will 1) analyze the flawed relationships between Taiwanese developers, architects, interior designers and homebuyers, explaining how these lead to inferior housing design and the waste of significant human, material and financial resources; and 2) then concludes a model of flexible design process integrated the concepts of human-centered design approach, Open Building and customization of Taiwanese townhouse developments. Consequently, such approach can significantly improve the flexibility of the present design process in terms of better meeting end-user requirements, the demands of sustainability, whilst ensuring the continued commercial viability of housing developments.

Authors: Chang Chia Lung , Kao Yan Huo , Jao You Lung , Chang Chih Laing
Published: March 2013

Hole drilling strain gage method is a semi-destructive measurement. The method is most commonly used to measure residual stresses. The relieved strains are measured around the drilled hole, and the residual stresses are estimated by the mechanical relationship between relieved strains and residual stresses as well calibration coefficients. The calibration coefficients indicate the relieved strains due to unit stresses within the hole depth. Finite element method is always used to determine the calibration coefficients, and the analytical model is based on the infinite plate. But the geometrical shape and size of cylindrical part are different from the infinite plate. The relieved strains around the drilled hole are different too. Finite element model of the cylindrical part is constructed to obtain the hole drilling calibration coefficients. The measurement of residual stresses in a cylindrical part subject to axial loading calculated by calibration coefficients of both infinite plate and cylindrical part model are compared to show the difference.

Authors: Lee Yi Yeh , See Aaron Raymond , Chen Shih Chung , Liang Chih Kuo
Published: March 2013

Frontal EEG asymmetry has been recognized as a useful method in determining emotional states and psychophysiological conditions. For the current research, resting prefrontal EEG was measured before, during and after listening to sad music video. Data were recorded and analyzed using a wireless EEG module with digital results sent via Bluetooth to a remote computer for further analysis. The relative alpha power was utilized to determine EEG asymmetry indexes. The results indicated that even if a person had a stronger right hemisphere in the initial phase a significant shift first occurred during audio-video stimulation and was followed by a further inclination to left EEG asymmetry as measured after the stimulation. Furthermore the current research was able to use prefrontal EEG to produce results that were mostly measured at the frontal lobe. It was also able to provide significant changes in results using audio and video stimulation as to previous experiments that made use of audio stimulation. In the future, more experiments can be conducted to obtain a better understanding of a person’s appreciation or dislike toward a certain video, commercial or other multimedia contents through the aid of convenient EEG module.

Mechanical Selection System of Stock Portfolio Based on Grey Relational Analysis Attribute Reduction Mechanism
Authors: Jane Chuen Jiuan
Published: March 2013

A stock portfolio selection system based on a Grey Relational Analysis (GRA) model, a Fuzzy C-Means (FCM) clustering scheme and Rough Set (RS) theory is proposed. In the proposed approach, 53 financial indices are collected automatically for each stock item every quarter and a GRA model is used to consolidate these indices into six predetermined financial ratios (Grey Relational Grades (GRGs)). The GRGs of the stock items are then clustered using a FCM scheme and the resulting cluster indices are processed using RS theory to identify the lower approximate set within the stock system. The stock items within the lower approximate set are filtered in accordance with established investment principles and the six GRGs of each surviving stock item are then consolidated to a single GRG indicating the overall merit of the corresponding stock item in terms of its ability to maximize the rate of return on the investment portfolio. The validity of the proposed approach is demonstrated using electronic stock data extracted from the financial database maintained by the Taiwan Economic Journal (TEJ). It is shown that the rate of return on the investment portfolio selected using the proposed GRA/FCM/RS system is higher than the average rate of return predicted by the variation in the Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX) over the same period. Thus, the feasibility of the GRA-based attribute reduction mechanism and the overall viability of the proposed portfolio selection system are confirmed. Introduction

Authors: Wu Chung Min , Chou Sheng Chun , Liaw Horng Twu
Published: March 2013

The stock market is a well-developed and mature market. Nevertheless, it is not immune to international financial market changes, where volatility has reigned in recent years. Investors who misgauge stock trends can suffer dramatic losses. Accurate identification of market trends can still achieve outstanding performance and has become a major investor concern. This paper proposes a new stock price trend clustering model using a genetic algorithm to search for optimal investment strategies. Daily stock prices and trading volume data from the Taiwan stock exchange weighted index (TAIEX) was used to examine the proposed trend clustering model’s performance. The model was also compared to other popular stock market investment strategies to verify its validity. Research results confirmed that the trend clustering model correctly identified three different trends in the stock market. Furthermore, the trend investment strategy model using genetic algorithms performed better than other investment strategies, i.e. Granville’s rules for buy and hold strategies, in both bull and bear markets. Research results confirmed trend investing outperformed the other two investment strategies in return and capital distribution, both during the training period and the testing period.
A Chaotic-Based Pseudo-Random Bit Generator for Navigation Applications
Authors: Chiang Yi Te , Wang He Sheng , Wang Yung Nien
Published: March 2013

In this paper, we propose a novel method to generate pseudo-random-noise (PRN) bits for navigation applications. In the present method, the code sequence generator is constructed based on two chaotic logistic maps running parallel and starting from independent initial conditions. The logistic map is a simple mathematical model that shows bewildering complex behavior. By appro-priately setting the initial conditions, the PRN sequence is then generated by comparing the outputs of both logistic maps. Several simulations are set up to verify the correlation properties of the pseudo-random bit generator (PRBG). The result shows that the code sequences generated by the proposed PRBG have great auto- and cross-correlation properties, which are very similar to the PRN sequences used by GPS navigation system. The RPBG sequences are therefore suitable for signal ranging that is used comprehensively in the navigation system. On the other hand, the chaotic nature of the proposed PRBG codes can provide more secure communication than the traditional PRN sequences. The proposed PRN sequences are well suitable to be incorporated with the so-called chaotic shift keying (CSK) modulation.

In the ideal case, gradient method can obtain higher precision than other methods when detecting the buried metal pipe by detector. But the parameter of coils and signal adjusting circuits cannot be the same because of the manufacturing errors, so it will lead to much error in the actual measurement. Many field experiments have been done in order to explore the law of error and reduce measurement error. From the point of experiment, this paper verifies that the errors of detecting buried metal pipe depth have linear distribution by using the gradient method without any other pipe interference. The precision of metal pipe detector can be improved to within ±5% by linear compensation.

Research on Comfort Performance of Green Building and Conventional Building
Authors: Li Na
Published: March 2013

t has been argued that green buildings have a better indoor environmental quality than conventional buildings and that this translates into a more satisfying workplace for the building's occupants and, inturn, a more productive workforce. Assessing a building's cost effectiveness means taking into account all the costs that will be incurred during its life cycle not just development costs. People found no evidence to believe that green buildings are more comfortable than conventional building. In fact, the only difference between the buildings was that occupants of the green building were more likely to perceive their work environment as warm, and occupants who felt warm were more likely to describe their work environment as poor.

Published: March 2013

The paper is mainly concerned with two parts in morphological observation and tissue culture of Eelgrass (Zostera marina L.).The results areas follows: 1.The microstructure of the plant showed that the cell wall exposing to seawater in epidermal cells of leaves was highly thickened, but the other sides were normal. It was also highly thickened in the side exposing to seawater in the epidermal cells of roots and stems. This structure may function as a barrier against toxic ions to enter the epidermal cells. Chloroplasts were found mainly in the epidermal cells, indicating that epidermal cells were main site where photosynthesis occurred. Aerenchyma was found everywhere in the plant which showed the ability of adaptation to submerged life. Anatomical observation of the inflorescence showed that eelgrass was a monoecious plant; the male flower and carpel were alternating arrangement on the inflorescence. SEM photographs of the stamen and the carpel indicated that the carpel had two stigmas; the pollens of the eelgrass were filamentous. All of the above observation showed that eelgrass is able to adapt to submerged life. The explants were dipped in 75%Alcohol for 10 seconds firstly, they were dipped in 1%NaClO 10 minutes, and this was the best way of sterilization than other treatments.
