In coastal processes, the strong water movements due to short periodic waves (such as sea swell) can induce irregular water level fluctuations in the swash zone and within the sandy beach. The measured water level fluctuations with very complex entry water level fluctuations in a wave canal with a sloping sandy beach were analyzed by using 7 capacitive sensors. Numerical simulations have also been...
Semi-supervised clustering incorporating biological relevance as a prior knowledge has been favored over the past decade. However, selection of prior knowledge has been a challenge. We generate prior knowledge from Gene Ontology (GO) terms at different levels of GO hierarchy and use them to study their impact on the performance of subsequent clustering of microarray data by using MPCKMeans and GOFuzzy...
More and more public data sets which contain information about individuals are published in recent years. The urgency to reduce the risk of privacy disclosure from such data sets makes the approaches of privacy protection for data publishing widely employed. There are two popular models for privacy protection: k-anonymity and l-diversity. k-anonymity focuses on reducing the probability of identifying...
Based on previous research achievements of marketing channel relationship and the status of channel relationship of China mobile phone market, the authors develop a conceptual model of influential factors of long-term orientation of channel relationship. Using data from a nationwide survey of 344 mobile phone distributors we test the effect of seven factors (Reputation, Specific Investment, Communication,...
This paper proposes a new texture description metric, the color distribution evenness (CDE) measure, and discusses its usage of performing multi-scale texture analysis. Further, CDE measure is applied to color-texture segmentation of natural images, upon which we propose the ISBEC (Image Segmentation Based on the distribution Evenness of Colors) algorithm. Experiments verify the effectiveness of CDE...
For omni-directional imaging based cooperative robot vision system, panorama unrolling is an important problem. We present an eight direction symmetry reuse algorithm for this problem, principles of this algorithm are: 1) Treat the original image to be unrolled as a series of co-centric circles, and uniformly partition them into eight parts of symmetrical sector regions. 2) According to symmetry principle...
Internet is used as one of major sources of health information. However, some studies show that the readability of health information presented on health Web sites is difficult for many consumers. Readability formulas usually measure difficulty of writing style, instead of difficulty of content. In order to recommend health information with appropriate reading level to consumers, we investigate the...
Designing and developing computer-based self-care tools faces challenges for modeling self-care decision making processes and monitoring self-care activities. In this paper, a simplified conceptual model for self-care decision making is presented and a workflow based self-care management system is proposed to implement the process-oriented monitoring. Self-care knowledge of specific conditions is...
