Regular Stereo Matching Improvement System Based on Kinect-supporting Mechanism  [PDF]
Din-Yuen Chan, Che-Han Hsu
Open Journal of Applied Sciences (OJAppS) , 2013, DOI: 10.4236/ojapps.2013.31B005
Abstract: In this paper, we built a stereoscopic video associated experimental model, which is referenced as Kinect-supporting improved stereo matching scheme. As the depth maps offered by the Kinect IR-projector are resolution-inadequate, noisy, distance-limited, unstable, and material-sensitive, the appropriated de-noising, stabilization and filtering are first performed for retrieving useful IR-projector depths. The disparities are linearly computed from the refined IR-projector depths to provide specifically referable disparity resources. By exploiting these resources with sufficiency, the proposed mechanism can lead to great enhancement on both speed and accuracy of stereo matching processing to offer better extra virtual view generation and the possibility of price-popularized IR-projector embedded stereoscopic camera.

Tzu-Han Yeh, Shih-Che Hsu, Che-Kai Chung, Ming-Shan Lin
Journal of Power and Energy Engineering (JPEE) , 2015, DOI: 10.4236/jpee.2015.34039
Abstract:

In this paper, a conformance test platform is built for intelligent electronic devices (IEDs) from different manufacturers based on IEC 61850 communication protocol. A conformance test of time delay of message transmission between two IEDs, made by the same or different manufacturers, is performed. The conformance test platform, as well as the test results provide a helpful reference for IEC 61850 implementation.

Poly[bis(μ2-4,4′-bipyridine)bis(3-nitrobenzoato)nickel(II)]
Shih-Chen Hsu,Sheng-Han Lo,Ching-Che Kao,Chia-Her Lin
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536810050117
Abstract: The crystal structure of the title complex, [Ni(C7H4NO4)2(C10H8N2)2]n, exhibits a two-dimensional network, which is built up from slightly distorted NiN4O2 polyhedra (2 symmetry), bipyridine ligands, and carboxylate anions. The NiII atoms are six-coordinated by two O atoms of two monodentate carboxylate anions and four N atoms from bipyridine ligands and are connected into layers by the 4,4′-bipyridine ligands.
SEPTIN12 Genetic Variants Confer Susceptibility to Teratozoospermia
Ying-Hung Lin, Ya-Yun Wang, Hau-Inh Chen, Yung-Che Kuo, Yu-Wei Chiou, Hsi-Hui Lin, Ching-Ming Wu, Chao-Chin Hsu, Han-Sun Chiang, Pao-Lin Kuo
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0034011
Abstract: It is estimated that 10–15% of couples are infertile and male factors account for about half of these cases. With the advent of intracytoplasmic sperm injection (ICSI), many infertile men have been able to father offspring. However, teratozoospermia still remains a big challenge to tackle. Septins belong to a family of cytoskeletal proteins with GTPase activity and are involved in various biological processes e.g. morphogenesis, compartmentalization, apoptosis and cytokinesis. SEPTIN12, identified by c-DNA microarray analysis of infertile men, is exclusively expressed in the post meiotic male germ cells. Septin12+/+/Septin12+/? chimeric mice have multiple reproductive defects including the presence of immature sperm in the semen, and sperm with bent neck (defect of the annulus) and nuclear DNA damage. These facts make SEPTIN12 a potential sterile gene in humans. In this study, we sequenced the entire coding region of SEPTIN12 in infertile men (n = 160) and fertile controls (n = 200) and identified ten variants. Among them is the c.474 G>A variant within exon 5 that encodes part of the GTP binding domain. The variant creates a novel splice donor site that causes skipping of a portion of exon 5, resulting in a truncated protein lacking the C-terminal half of SEPTIN12. Most individuals homozygous for the c.474 A allele had teratozoospermia (abnormal sperm <14%) and their sperm showed bent tail and de-condensed nucleus with significant DNA damage. Ex vivo experiment showed truncated SEPT12 inhibits filament formation in a dose-dependent manner. This study provides the first causal link between SEPTIN12 genetic variant and male infertility with distinctive sperm pathology. Our finding also suggests vital roles of SEPT12 in sperm nuclear integrity and tail development.
Taiwanese Gambling Behaviors, Perceptions, and Attitudes  [PDF]
Cheng-Wei Chung, Jiun-Jia Hsu, Che Hao Chang
American Journal of Industrial and Business Management (AJIBM) , 2013, DOI: 10.4236/ajibm.2013.31014
Abstract:

This study categorizes different Taiwanese gambling types using Problem Gambling Severity Index (PGSI), and further evaluates the perceptions and attitudes toward the legalization of casino gambling. A survey was conducted using convenient sampling and distributed by Internet. Results indicate that across groups of different types of gamblers, there are significant differences in perceptions toward the legalized casino gambling industry; and there are significant differences in attitudes toward legalized casino gambling. Additionally, there are significant differences between perceptions toward the legalized casino gambling industry, and attitudes toward the legalization of casino gambling. In general, non-gamblers are relatively more conservative toward the development of the casino gaming industry due to non-gam- blers’ sensitivity toward the involvement of the economic and social costs involved in investing in this particular indus- try. In addition, the results of this study provide the Taiwangovernment with information about Taiwanese gambling behaviors and opinions toward newly legalized gambling. By understandingTaiwanresidents’ gambling behaviors, perceptions, and attitudes prior to the opening of the casinos, this study could benefitTaiwansociety and maximize the benefits and minimize the costs associate with the development of the casino industry.

First-principles study of intermediate-spin ferrous iron in the Earth's lower mantle
Han Hsu,Renata M. Wentzcovitch
Physics , 2014, DOI: 10.1103/PhysRevB.90.195205
Abstract: Spin crossover of iron is of central importance in solid Earth geophysics. It impacts all physical properties of minerals that altogether constitute $\sim 95$ vol\% of the Earth's lower mantle: ferropericlase [(Mg,Fe)O] and Fe-bearing magnesium silicate (MgSiO$_3$) perovskite. Despite great strides made in the past decade, the existence of intermediate-spin (IS) state in ferrous iron (Fe$^{2+}$) (with total electron spin $S=1$) and its possible role in the pressure-induced spin crossover in these lower-mantle minerals still remain controversial. Using density functional theory $+$ self-consistent Hubbard $U$ (DFT$+U_{sc}$) calculations, we investigate all possible types of IS states of Fe$^{2+}$ in (Mg,Fe)O and (Mg,Fe)SiO$_3$ perovskite. Among the possible IS states in these minerals, the most probable IS state has an electronic configuration that significantly reduces the electron overlap and the iron nuclear quadrupole splitting (QS). These most probable IS states, however, are still energetically disfavored, and their QSs are inconsistent with M\"{o}ssbauer spectra. We therefore conclude that IS Fe$^{2+}$ is highly unlikely in the Earth's lower mantle.
A Review of Accelerometry-Based Wearable Motion Detectors for Physical Activity Monitoring
Che-Chang Yang,Yeh-Liang Hsu
Sensors , 2010, DOI: 10.3390/s100807772
Abstract: Characteristics of physical activity are indicative of one’s mobility level, latent chronic diseases and aging process. Accelerometers have been widely accepted as useful and practical sensors for wearable devices to measure and assess physical activity. This paper reviews the development of wearable accelerometry-based motion detectors. The principle of accelerometry measurement, sensor properties and sensor placements are first introduced. Various research using accelerometry-based wearable motion detectors for physical activity monitoring and assessment, including posture and movement classification, estimation of energy expenditure, fall detection and balance control evaluation, are also reviewed. Finally this paper reviews and compares existing commercial products to provide a comprehensive outlook of current development status and possible emerging technologies.
Entropy for Business Failure Prediction: An Improved Prediction Model for the Construction Industry
Jay Bal,Yen Cheung,Hsu-Che Wu
Advances in Decision Sciences , 2013, DOI: 10.1155/2013/459751
Abstract: This paper examines empirically the effectiveness of entropy measures derived from information theory combined with discriminant analysis in the prediction of construction business failure. Such failure in modern complex supply chains is an extremely disruptive force, and its likelihood is a key factor in the prequalification appraisal of contractors. The work described, using financial data from the Taiwanese construction industry, extends the classical methods by applying Shannon's information theory to improve their prediction ability and provides an alternative to newer artificial-intelligence-based approaches. 1. Introduction Over the last 35 years, business failure prediction has become a major research domain especially with increased global business competition [1]. Business failure is an extremely disruptive force in the construction industry [2]. Kangari et al. [3] indicated that the construction industry in the USA has several unique characteristics that sharply distinguish it from other sectors of the economy. The bankruptcy rate within the American construction industry has been increasing in recent years and the USA has the highest percentage of construction company failures each year [4, 5]. The construction industry is also a major industry in the UK and has the highest percentage of company failures each year [6, 7]. Similarly, in Asian countries like Taiwan where there has been phenomenal growth in the last few decades, the construction sector also plays a major economic role. Beaver [8] was one of the first researchers to study business failure prediction. He analysed financial ratios one by one to evaluate their predictive ability. He then developed their predictive abilities using cutoff scores to classify each company as either failed or nonfailed company. However, this classification technique uses one ratio at a time and conflicts arise when one ratio classifies the company as healthy whilst another detects distress. His work was followed by Altman’s [9] model based on discriminant analysis and Ohlson’s work [10] based on the use of logistic regression. Like many other problems in science and engineering, popular machine learning techniques from the 1990s such as neural networks and genetic algorithms have also been applied to business problems such as bankruptcy or business distress detection [11, 12] with some successes. When qualitative data and uncertainties abound, these techniques are very useful indeed. However, techniques such as artificial neural networks require large datasets for training purposes and large models are
Active Queue Management within Large-Scale Wired Networks  [PDF]
Ping-Min Hsu, Chun-Liang Lin, Ching-Han Yu
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2011, DOI: 10.4236/ijcns.2011.44029
Abstract: Signal transmission control protocol sources with the objective of managing queue utilization and delay is actually a feedback control problem in active queue management (AQM) core routers. This paper extends AQM control design for single network systems to large-scale wired network systems with time delays at each communication channel. A system model consisted of several local networks is first constructed. The stability condition guaranteeing overall stability is subsequently derived using Lyapunov stability theory. The results developed have been successfully verified on a network simulator.

Mei-Hui Lin, Tsai-Fu Chuang, Han-Pin Hsu
Journal of Service Science and Management (JSSM) , 2014, DOI: 10.4236/jssm.2014.73017
Abstract:

The objective of this study is to investigate the relationship among teachers’ teaching beliefs, student-centred teaching concept and instructional innovation in Taiwan. The study was conducted with the participation of 538 teachers of elementary schools. A questionnaire of the “teaching beliefs and instructional innovation” designed by the authors was used as the data collection instruments. The descriptive statistics, Pearson product-moment correlation and multiple regression analysis were used in this study. Analysis results showed that: 1) There is a positive relationship between the teaching beliefs and the instructional innovation. 2) Teacher with a high degree of student-centred teaching concept would exhibit a higher level style of instructional innovation. 3) Multiple regression analysis can be used to infer causal relationships between the teachers’ teaching beliefs and instructional innovation.
