Electrode layout of ZnO pyroelectric sensors

Chun-Ching Hsiao,Shih-Yuan Yu 대한기계학회 2011 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.25 No.11

In the present study, an electrode layout of pyroelectric sensors is developed to improve electric signals. Voltage responsivity is a main target to enhance the performance of pyroelectric sensors. A partially covered, top electrode has been proven to effectively increase the voltage responsivity of pyroelectric sensors. In the experimental results, the proposed electrode layout with an array type in ZnO pyroelectric sensors possessed higher voltage signals, about 3.6 times that of a fully covered type, and about 2 times that of a partially covered type. Moreover, a finite element model is used to explore the temperature variation rate in ZnO pyroelectric sensors for both the fully covered and the partially covered electrodes. In the simulation results, the partially covered electrode can indeed improve the temperature variation rate in the ZnO layer.

Hsiao-Hsuan Hsu,Chun-Yen Chang,Chun-Hu Cheng 한국물리학회 2013 Current Applied Physics Vol.13 No.7

We report a room-temperature and high-mobility InGaZnO thin-film transistor on flexible substrate. To gain both high gate capacitance and low leakage current, we adopt stacked dielectric of Y2O3/TiO2/Y2O3. This flexible IGZO TFT shows a low threshold voltage of 0.45 V, a small sub-threshold swing of 0.16 V/decade and very high field-effect mobility of 40 cm2/V. Such good performance is mainly contributed by improved gate stack structure and thickness modulation of IGZO channel that reduce the interface trap density without apparent mobility degradation.

Evaluation of Ride Comfort for Active Suspension System Based on Selftuning Fuzzy Sliding Mode Control

Chun-Yu Hsiao,Yu-Hsien Wang 제어·로봇·시스템학회 2022 International Journal of Control, Automation, and Vol.20 No.4

This paper describes the application of a self-tuning fuzzy sliding mode controller (STFSMC) to design the control signal of an electro-hydraulic actuator under standard road excitation based on ISO 8608. The proposed damper was designed to achieve effective vibration isolation with an actuator force. The proposed damper was incorporated into a quarter-car system through experiments for the subsequent dynamic analysis of the suspension system. A single-input single-output (SISO) fuzzy inference was strategically used to regulate the slope of a sliding surface. In addition, the fuzzy control methodology was applied to achieve self-tuning online output of the scale factor of the fuzzy sliding mode controller. The comfortable riding time and ride comfort level were also evaluated based on ISO 2631-1. Experimental results revealed that the proposed controller demonstrated evident improvements in vehicle vibration suppression and the ride quality in comparison with passive and fuzzy logic controller control systems.

Antenatal Depression in East Asia: A Review of the Literature

Mei-Chun Hsiao,Mei-Chun Hsiao,Chia-Yih Liu 대한신경정신의학회 2012 PSYCHIATRY INVESTIGATION Vol.9 No.2

This current study’s goal is to summarize the literature regarding Antenatal Depression (AD) in the East Asian countries of Taiwan, China (including Hong Kong and Macau), Japan, and Korea. The main search utilized a Pub med Chinese Electronic Periodical Service (CEPS) literature review using keywords ‘AD’, and ‘Prenatal Depression’ with searches for ‘Japan’, ‘Korea’, ‘Taiwan’, ‘Hong Kong’ and Macau’. The rates of AD in East Asia appear to be relatively close to those in the Western literature, although certain studies showed slightly decreased rates. Many of the risk factors for AD were the same in the Eastern and Western literature. These risk factors included demographic factors such as younger age, smoking, low education and income, and unemployment. Other risk factors were physical symptoms such as menstrual pains and nausea. Finally, psychological factors such as a poor response to the pregnancy, poor spousal support, and poor family support were associated with AD. With regard to treatment, there were no studies examining the administration of psychotropic medications for AD. The literature from East Asia both confirmed many Western findings and made unique contributions to the literature on AD. The treatment of AD in East Asia appears to be an entity which, despite its morbidity, has not been adequately studied.

Low power resistive random access memory using interfaceengineered dielectric stack of SiOx/a-Si/TiOy with 1D1R-like structure

Chun-Hu Cheng,K.I. Chou,Zhi-Wei Zheng,Hsiao-Hsuan Hsu 한국물리학회 2014 Current Applied Physics Vol.14 No.1

In this study, we report a resistive random access memory (RRAM) using trilayer SiOx/a-Si/TiOy film structure. The low switching energy of <10 pJ, highly uniform current distribution (<13% variation), fast 50-ns speed and stable cycling endurance for 106 cycles are simultaneously achieved in this RRAM device. Such good performance can be ascribed to the use of interface-engineered dielectric stack with 1D1R-like structure. The SiOx tunnel barrier in contact with top Ni electrode to form diode-like rectifying element not only lowers self-compliance switching currents, but also improves cycling endurance, which is favorable for the application of high-density 3D memory.

Psychometric Testing of Behavior Assessment for Children

Hsiao-Ling Chuang,Ching-Pyng Kuo,Chia-Ying Li,Wen-Chun Liao 한국간호과학회 2016 Asian Nursing Research Vol.10 No.1

Purpose: The purpose of this study was to test the reliability and validity of the Behavior Assessment for Children (BAC) in a community of school-aged children in Taiwan. Method: A school-based sample comprising third grade and fourth grade students was recruited from Taichung City in Taiwan. The parents (n = 248) and teachers (n = 15) of these students completed structured questionnaires, including the Child Behavior Checklist (CBCL) and the proposed BAC. Content validity, concurrent validity, construct validity, internal consistency, and inter-rater reliability of the BAC were assessed. Results: The BAC comprised three subscales (attention, emotion, and self-control) that included 17 items. The content validity index (CVI) score was 0.98. The result of the confirmatory factor analysis (goodness of fit = .90, root mean square of residual = .03, root mean square error of approximation = .06, and comparative fit index = .94) supported the construct validity of the three BAC subscales. The concurrent validity of the BAC subscales significantly correlated with the compatible CBCL subscales (r = .59-.78, p < .001). Cronbach a of the subscales of the BAC ranged from .78 to .92. The intraclass correlation coefficient between the parents and teachers ranged from .31 to .44, and the joint probability of agreement ranged from 31.4% to 92.2%. Conclusions: The BAC is a valid and reliable instrument for evaluating behavioral problems in schoolaged children.

Due to raising population of tourism and popular experiential tour, more and more people have invested in building their dreamlike Bed & Breakfast (B&Bs). However, B&B industry faces a tight situation because of the growth of B&Bs, especially on competitive travel website. In particular, we can find out a variety of B&Bs‘ images at the same page of travel websites At limited web space and a variety of competitors, how to attract consumers to click it is the primary issue. What kind of image, information, or keywords may influence customers’ decision? This study discusses the attractive factors of Taiwanese B&B on travel websites and the result information can help B&B hosts develop effective advertising and promotional plans. In this study, we chose 127 B&B images which show the first sight of B&Bs from travel websites. The research was divided into three steps. In the first step, Evaluation Grid Method (EGM) was applied to construct attractive factors of B&Bs from interviews. In the second st ep, the hierarchical diagram of EGM was further adopted to organize a questionnaire. A nd then, quantitative type I method was applied to analyze the data collected from the questionnaires. A total of 37 valid samples were collected in this experiment. The main impact factors of four attractiveness aspects of B&Bs information were obtained: "theme style" for " distinguishing characters " aspect, "reunion" for " leisure atmosphere ", "uni que style" for " style of B&B ", and " word of mouth‖. for "satisfaction" aspect. In the third step, cluster analysis was employed to identify the visitor groups as following: peo ple who like characteristic things and relax environment, people who enjoy interacting w ith their friends, family and B&B hosts, and people who are interesting in making com parison of B&Bs and book B&Bs online habitually. The findings of this study may assi st B&B host in promotion and advertising on travel websites more efficiency.
