6 106/2 化材系 黃招財 助理教授 會議論文 發佈 Study on the mechanism of the Surface Defect of the Ceramic Injection molded (CIM) Insulator , [106-2] 摘要:Insulators have been applied in many fields, such as in industry, medical, or military very often. Especially, in high voltage environments, insulator plays a very important role. In general, inorganic or plastic materials are used for the low voltage insulator, but the ceramic material is applied for fabricating the high voltage insulator. The most common method to fabricate ceramic insulator is ceramic powder injection molding (CIM). Based on this method, the good quality for high voltage and mass production can be obtained. In general, the ceramic powder and some plastic are mixed, and then the mixed material is delivered into injection molding process. The major procedures can be divided as the mixing of the ceramic powder and plastics to prepare the feedstock, injection molding to make the green parts, thermal debinding, sintering, and post processing [1-3]. As the CIM process is performed, some surface defects will be generated during the injection molding step. These surface defects will become very serious problem after thermal debinding and sintering. Recently, some researchers suggested that those surface defects could be related to the non-symmetrical volume shrinkage during the injection molding period in the formation of green parts. Thomas and Evans [4] have tried to applied alumina to make ceramic green part. They found out some tiny crack in green parts where would become a big crack. They proposed that the final crack is strongly related to the molding process. Jansen et al [5] tried to understand how the shrinkage behavior happened in injection molding. They had systematically considered various operation conditions including injection speed, package pressure, melt temperature, and mold temperature for seven polymer materials. They found out the major factors to influence the volume shrinkage of injected parts are melt temperature and packing pressure. Moreover, German [6] suggested that the improper high melt temperature will enlarge the defects. The non-uniform volume shrinkage will cause the void and crack defects for the final products. Although many researchers proposed that the surface crack defect is related to green parts during the injection period, how the quantitative relationship is not fully understood yet. Hence, in this paper we will try to build this relationship between the surface defects of final ceramic product and the physical property of the green parts during the injection molding.
7 106/2 化材系 黃招財 助理教授 會議論文 發佈 Study on the Main Driving Force to Cause the Variation of the Core Material Penetration Behavior in Different Materials Arranged Co-injection Molding , [106-2] 摘要:Co-injection molding is widely used in our daily life for manufacturing soft-feel skin/hard core, virgin skin/recycled core, and many other arranged products. However, there are still too many combinations of designs and parameters to cause that the interface between skin and core materials is not easy to be well controlled. In this study, we have applied three different material combination, say PS/PS, PS/PP, and PS/ABS. For each combination, it can be arranged as low viscosity-to-high viscosity (Low/High) or high viscosity-to-low viscosity (High/Low) structure. Results showed that at PS/PS system with a unique skin-to-core ratio and a fixed flow rate, general operation parameters have no significant effect on the change of the interface between skin and core. As in PS/PS combination with Low/High structure, it generates longer and narrower locus. On the other hand, as in High/Low structure, it generates shorter and wider locus. Moreover, as considered the different material combination, PS/PP and PS/ABS with Low/High structure, the core penetration trend of the longer and narrower locus is similar as that of PS/PS system with the same structure. However, the core penetration distance is influenced significantly by the materials. Furthermore, to get more precision prediction on the core penetration distance, it is investigated through the interaction among various material properties and time domain. Results showed that in Low/High structure, the different core penetration distance behavior is proportional to the dynamic change of the viscosity as time period proceeded. Finally, some experimental studies are also performed to verify the numerical predictions. In the general core penetration measurement, the numerical prediction is in a good agreement with the experimental data in trend.
8 106/2 化材系 黃招財 助理教授 會議論文 發佈 Study on the Influences on Fiber Micro-structure Variations and the Connection to Final Shrinkage/Warpage on Long Fiber Reinforced Thermoplastics (FRT) Parts , [106-2] 摘要:Because of its great potential and capability, the fiber-reinforced thermoplastics (FRT) material and technology have been widely utilized into industry recently. However, due to the microstructures of fiber inside plastic matrix are very complex, they are not easy to be visualized. The connection from microstructures to the final shrinkage/warpage is still not fully understood yet. In this study, we have performed a benchmark with three standard specimens based on ISO 527 where those specimens have different gate designs. Due to the geometrical effect, the warpage behaviors are quite different for those three specimens. Specifically, it pushes one specimen warped downward and bended inward, another warped upward, and the other slightly upward at the same time. The difference might be due to the interaction of the entrance effect of molten plastic with fiber content to cause high asymmetrical fiber orientation distribution (FOD). Moreover, the experimental study is also performed to validate the simulation results. From short shot testing to the warpage and bending measurement for each individual model, overall, the tendency for both numerical simulation and experimental results is in a reasonable agreement. However, to get better understand between the microstructures of the fibers and the final shrinkage/warpage, it still needs for further more study
9 106/2 化材系 黃招財 助理教授 會議論文 發佈 Investigation on the P-V-T-C Property Characterization and Its Importance on IC Encapsulation Material Application , [106-2] 摘要:In recent years, various modern technologies such as internet of things (IoT), Automation, Industry 4.0, lead IC chips and related components to higher performance and more strict specification. To fit this trend, EMC or some chemical cured material is widely used as the insulation and package material in plastic IC encapsulation industry. However, during IC encapsulation process, shrinkage and warpage will be one of the main problems for quality control. More specific, how to precisely estimate the causes of volume change during the processing and then manage them is still very challenge. In this paper, we have proposed some new designs to extend previous literature’s concept using a single plunger type dilatometer to measure the volume change interacted with pressure and chemical conversion. Results showed that in the new specimen chamber design with smaller diameter and longer height the precision tolerance can be improved from 1m to 0.01m. The output volume change history curve became more smoothly and robotically. Furthermore, through various testing for general thermoplastic and EMC materials based on our new heating system, the real volume change behavior with or without chemical reaction is in good agreement with that of literatures. Moreover, the obtained measured data has integrated into Moldex3D to perform some real IC complicated design encapsulation process testing, results present that when the system was covered both thermal and chemical shrinkage, the warpage trend can be precisely predicted; however, if it is only considered the thermal shrinkage, the warpage prediction will be opposite to the real one. It displayed how the chemical shrinkage estimate is so important in IC Encapsulation industry

13 107/1 風保系 汪琪玲 教授 會議論文 發佈 Estimating Risk Preferences for Most Investors , [107-1] 摘要:This paper adopts individual portfolio choice data to estimate the preference parameters in almost stochastic dominance (ASD). ASD is a decision criterion for most decision makers to rank distributions on the basis of riskiness. Existing empirical studies have shown that ASD is helpful in explaining some puzzles in …nance and could be applied to evaluate investment strategies. Their conclusions heavily rely on the estimation of the preference parameters in the ASD rules provided by Levy et al. (2010). However, the estimation of Levy et al. (2010) is obtained from arti…cial tasks designed in a lab- oratory by using students as subjects and adopts an incorrect condition for the almost second-degree stochastic dominance. Our paper is the …rst to use empirical observations in portfolio choice decisions and to adopt the correct conditions to estimate the pref- erence parameters in ASD. Our estimation shows that these preference parameters are much lower than the numbers in Levy et al. (2010). Since these parameters serve as upper bounds to obtain the unambiguous prediction on the ranking of distributions, our …ndings suggest the needs of re-examination on the existing empirical conclusions.
14 106/2 航太系 汪愷悌 助理教授 會議論文 發佈 Observations of energetic protons by Van Allen Probes at radiation belts during solar proton events , [106-2] 摘要:Solar proton events have been recorded based on the criteria when the proton fluxes at energies larger than 10MeV measured by GOES spacecraft at geosynchronous orbit exceeds or equals 10 pfu (particle flux unit) for a continuous time. These events have been observed to affect the atmosphere and ionosphere through the Earth’s poles in the form such as enhanced ionization causing radio signal absorption. Some events with intensified fluxes at higher energies (e.g., >100MeV) may be even possible to cause damages on spacecraft in the magnetosphere. Since the Relativistic Proton Spectrometer (RPS) carried by Van Allen Probes, launched on August of 2012, are able to measure protons with energies above ~ 60 MeV up to ~ 2 GeV, in this study, we analyze available observations from RPS during periods of solar proton events for the Solar Cycle 24. Comparisons in the observed fluxes at different energy levels with the intensities of solar proton events will be made through temporal and spatial analyses. This will enhance our understanding on changes in proton fluxes with energies higher than the order of 100 MeV as well as effects on the radiation belts from solar proton events with different intensities.

19 106/2 機電系 康尚文 教授 會議論文 發佈 Experimental Investigation on Startup and Thermal Performance of a High Temperature Heat Pipe , [106-2] 摘要:Heat pipe play an important role in high temperature energy transfer system and storage system. It can be applied to the areas such as solar energy storage system and waste heat recovery. High temperature heat pipes with 420mm in length, 13mm in outer diameter and 2mm in tube thickness have been developed and tested. The device was made of Inconel 600 equipped with a 316 stainless-steel 100 mesh wick. The working fluid was metal sodium with a filling ratio of 10% (2.86g). Heat pipes start-up and thermal characteristics were investigated at different orientations with slopes of -15°, 0°, +45° and +90° while heat sink temperatures were kept at 27°C air environment. The evaporator temperature of 800°C was achieved when the input power was set at 790W. It has been found that the lowest value of the heat pipes thermal resistance was 0.11 °C/W when the inclination angle was at 90°
20 106/2 機電系 康尚文 教授 會議論文 發佈 Development of Heat Pipe Heat Exchanger , [106-2] 摘要:In this study, the gas-to-liquid heat pipe heat exchanger was fabricated and tested, and the thermal recovery capability and thermal performance of heat pipe heat exchangers were investigated. The device consist 19 stainless steel-water heat pipes with an outside diameter of 6.2 mm, a wall thickness of 0.5 mm and a length of 300 mm. The experiment was conducted at conditions for which hot gas and cooling waters enter at temperatures of 150-250 ºC and 30ºC, respectively. The flow rate of gas through the evaporator is at the range of 0.114-0.270 kg/min, while the flow rate of water through the condenser is 0.940 kg/min. The results showed that the maximum heat transfer rate was 445.5 W, and the maximum effectiveness was 0.609. The present research was also carried out the comparison between experimental and theoretical investigation with reference to the correlation in the literature.
21 106/2 風保系 湯惠雯 副教授 會議論文 發佈 CEO Compensation, Board Compensation and Earnings Management , [106-2] 摘要:This study investigates the relationship between excess director compensation and CEO compensation, and the influence of CEO compensation due to excess director compensation on earnings management using firms covered by Standard and Poor’s ExecuComp database during 2007 and 2016. The results show that the characteristics of board of directors, CEOs, and company have a significant impact on the compensations of directors and CEOs. Excess director total compensation, i.e., those cannot be explained by the above characteristics, has a significant positive influence on CEOs’ cash compensation, incentive awards, total compensation and the exercise value of stock options. The parts of CEO’s cash compensation, incentive compensation, total compensation and the exercise value of stock options, which are affected by excess director compensation, have positive and significant effects on aggregate earnings management. This result indicates that the higher the CEO’s compensations, which are affected by excess director compensation, the more the CEO will increase profits by manipulating earnings. This study infers that the increases in these parts of CEO compensations are likely to be the result of earnings management based on common interests between the CEO and the board of directors, rather than a company’s complicated business or high risk, which requires highly-professional CEOs to work together with the board.
22 106/2 土木系 葉怡成 教授 會議論文 發佈 Building multi-factor stock selection models with experimental designs and multi-variable polynomial regression analysis – Empirical evidences from Taiwan stock market , [106-2] 摘要:Some literature adopted a weighted-scoring approach to construct the multi-factor stock selection model. However, this approach leads to two shortcomings. First, it cannot effectively identify the connection between the weights of stock-picking concepts and portfolio performances. Second, it cannot provide the optimal combination of weights of stock-picking concepts to meet various investors’ preferences. This paper aims to employ a mixture experimental design to collect the weights of stock-picking concepts and portfolio performance data, as well as to build up performance prediction models based on the weights of stock-picking concepts with multi-variable polynomial regression analysis. Furthermore, these performance prediction models and optimization techniques are employed to discover the optimal combination of weights of stock-picking concepts. The samples consist of all stocks listed in the Taiwan stock market. The 1997-2008 period and the 2009-2015 period are employed as the modeling period and the testing period. Empirical evidences showed that (1) our methodology is robust in predicting performance accurately, and can discover significant interactions between the weights of stock-picking concepts. (2) It can discover the optimal combination of weight of stock-picking concepts which can form stock portfolios with the best possible performances to meet investors’ preferences. Thus, our methodology is able to resolve the two shortcomings of classical weighted-scoring approach.
23 105/2 土木系 葉怡成 教授 會議論文 發佈 Using Quantile Neural Networks to Estimate the Distribution of Enterprise Values for Construction Enterprise , [105-2] 摘要:In the cases of corporate investment, financing, or transactions, the probability density function of enterprise values may be more useful. This paper proposes a novel method of employing prediction results of the quantile neural networks to build probability density functions with which we may effectively assess enterprise values. Empirical evidence reveals that the estimated cumulative lognormal distribution curves of the Price-to-Book value ratio (PBR) and the data are well-matched. Thus, the corporate market value is also a lognormal distribution. PBR distributions of construction industries are more skewed to the left, implying that enterprise values of construction industries are lower than those of other industries with the same stockholder equity.

29 106/1 機電系 王銀添 教授 會議論文 發佈 Visual Moving Objects Tracking Using Shape Detectors and Object Models , [106-1] 摘要:This paper presents an algorithm of robot visual moving-object tracking (MOT) based on the probabilistic object model with a pe-destrian detector. Three major research topics investigated in the study include the combination of moving feature detection and pe-destrian detection, the improvement of probabilistic object model, and the tuning mechanism of object model training. The developed MOT was further integrated with the visual simultaneous localiza-tion and mapping (vSLAM) to form a simultaneous localization, mapping, and moving object tracking system. The extended Kalman filter (EKF) was used to estimate the system states and the speeded-up robust features (SURFs) were employed to represent the visual environment map. Experiments were carried out in this research to validate the performance of the developed systems.
30 106/2 資圖系 陳亞寧 副教授 會議論文 發佈 An FRBR-based approach for transforming MARC records into linked data , [106-2] 摘要:In this study, a practical workflow is outlined for transforming MARC records into Linked Data according to classes and properties of FRBR and FRAD defined in the RDA Registry. Four bibliographic records of ‘Pride and Prejudice’ were selected as subject, one was English and the other were Chinese records to illustrate the hidden relationships embedded in MARC records, including translation, version and reproduction, relationships between classes in FRBR group 1, and relationships between FRBR group 1 and FRAD for Linked Data. In total, the proposed workflow is composed of three stages and five tasks as follows: data preparation and selection (comprising two tasks. i.e., changing MARC tags into semantic labels with their data and selecting significant labels and their data for Linked Data), data modeling (comprising two tasks, i.e., aligning MARC labels and their data with semantic equivalent classes defined in the RDA Registry and building the relationships between selected classes through the properties of the RDA Registry), and reusing existing value vocabularies for external linking (comprising one task, such as linking terms from VIAF, TGN and so on). Issues related to de-duplication and collaboration of LD are also addressed.
