The associations between different modalities of Web images could be very useful for Web image retrieval. In this paper, we investigate the multi-modal associations between two basic modalities of web images, i.e. keyword and visual feature clusters, by data mining technique. The association rule crosses two modalities, in which the antecedent is a single(More)
The purpose of this study is to investigate the impacts of bicyclo-monoterpene promoters (i.e., borneol and camphor) on the in vitro permeation of ligustrazine (LGT) through the hairless porcine dorsal skin. Fourier transform-infrared (FT-IR), scanning electron microscope (SEM) and transdermal delivery kinetics in vitro were performed to investigate the(More)
The bandwidth and reliability of the reverse link (or uplink) as the performance metrics of real-time traffic are studied in this paper. A two-level full factorial design of experiment (DOE) was conducted to identify the impact on the bandwidth and reliability of four factors: packet size, data streaming rate, time of the day, and buffer size in a real(More)
From the driving strategy point of view, a major challenge for autonomous vehicles in urban environment is to behave defensively to potential dangers, yet to not overreact to threats with low probability. As it is overwhelming to program the action rules case-by-case, a unified planning framework under uncertainty is proposed in this paper, which achieves a(More)
<em>Energy</em> is often the most constrained resource for battery-powered wireless devices and the lion&#226;€™s share of energy is often spent on transceiver usage (sending/receiving packets), not on computation. In this paper we study the <em>energy complexity</em> of Leader Election and Approximate Counting in several models of wireless radio networks.(More)
With technology of digital image recognition, the data frames include vehicle’s digital image can be detected automatically from an Audio Video Interleaved (AVI) File, and vehicle type will be recognized automatically. The system consists of four modules: Reading AVI file and decomposing it into digital image frames; Motion detection; Vehicle’s digital(More)
Latent Semantic Indexing (LSI) and Relevance Feedback (RF) have been shown to be extremely useful in information retrieval respectively. But at the context of Web image retrieval, LSI is limited for the Single Value Decomposition (SVD) computation cost to large dataset while RF is confused with the reluctance of interaction for most Web users. In this(More)
