In order to achieve the time domain load signals of CNC lathe during the cutting process, a new signal processing method based on improved Neighbor Block was proposed according to the character of noise in this paper. First, statistical variance smoothing method was utilized to remove the singular points. Then, denoising method of Neighbor Block was chosen. Finally, feasibility of wavelet basis was...
An experiment was conducted in a fixed-base driving simulator to observe young drivers' their physiology changes under high mental workload, while responding to two sets of mental tasks: n-back and sound counting. 20 drivers (9 of them younger than 25 (range 21–24) and 11 older than 25 (range 29–33) were instructed to drive along two sections on a highway at a constant speed. NASA-TLX scores for workload...
Background TAZ is a downstream agent of Hippo signal pathway. β-catenin is a cell adhesion molecule associated with the invasion and metastasis of carcinomas as well as a critical component of Wnt pathway. TAZ and β-catenin have long been thought to play a vital role in tumour development and progression. This study aimed to detect expression of TAZ and β-catenin in adenocarcinoma of the esophagogastric...
Most existing intelligibility indices require access to the input (clean) reference signal to predict speech intelligibility in noise. In some real-world applications, however, only the noise-masked speech is available, rendering existing indices of little use. The present study assessed the performance of an intelligibility measure that could be used to predict non-intrusively (i.e., with no access...
E-learning has become a new technology in the educational field recently because of development of information communication technology. Therefore, the Department of Education, Taipei City Government constructed a digital platform based on the internet, named Easy Teaching Web of Taipei (ET Web), for teachers and academic staffs to surf in 2003. For the purpose of analyzing the effectiveness of the...
In the digital era, using information technology to search valuable information is one of the important skills. Taipei City Government set up Easy Teaching Web of Taipei, integrates scattered knowledge in the field of education and human resources, and build a knowledge-sharing platform for teachers. However, it is still important to understand how to improve the usage of Easy Teaching Web of Taipei...
This paper establishes a quantitative model of bullwhip effect under the max-min inventory management system with the market demand subjecting to the AR (1) demand process in a simple two-level supply system including a single supplier and a single retailer, resulting that the bullwhip effect will be extended with the increasing of lead time and service level. The result couldprovide some significant...
The beam propagation factor and kurtosis parameter of broadband Gaussian shell-model beams propagating in free space are studied numerically based on the intensity moments. The effects of spectral bandwidth and spatial correlation length on these two parameters are analyzed. The beam propagation factor or kurtosis parameter of beams with broader spectral bandwidth and smaller correlation length becomes...
Land use/cover change (LUCC) is an important component of global change research. Based on Geostatistics and taking the TM images in 1985 and ASTER images in 2002 in Fujian Province, the TM images in 1988 and the ASTER images in 2004 in Fuzhou City as the data sources, the present paper built the human impact indexes, compiled the human impact indexes maps and the human impact indexes change maps,...
