Contextual factors can influence health through exposures to health-promoting and risk-inducing factors. The aim of this study was to (1) build, from geotagged Twitter and Yelp data, a national food environment database and (2) to test associations between state food environment indicators and health outcomes.This is a cross-sectional study based upon secondary analyses of publicly available data...
Wireless capsule endoscopy (WCE) is a revolutionary imaging technique that enables direct inspection of the gastrointestinal tract in a non-invasive way. However, viewing the large amounts of images is a very time-consuming and labor intensive task for clinicians. In this paper, we propose an automatic bleeding detection method in the WCE images. We propose a two-stage saliency map extraction method...
In the current medical world, B-ultrasound is usually utilized as the detection technique of fatty liver. However, because of the image resolution at B-Ultrasound is limited, the technique is inadequate to after quantitative data to help doctors make decisions and judgments. Therefore, doctors instead make decisions based on their precedent experiences, which are arguably not precise in many cases...
How to extract envelopes accurately is the most important problem in analyzing heart sound signals, especially for abnormal heart sound signals. An effective envelope extraction is a key to the detection of S1 and S1 periods and noise separation, moreover, for estimating the type of heart disease. This paper compares six efficient envelope extraction methods based on abnormal heart sounds, with comparisons...
This research is part of the ongoing multinational collaboration ldquoAsian English speech corpus projectrdquo (AESOP), whose aim is to build up an Asian English speech corpus representing the varieties of English spoken in Asia. AESOP is an international consortium of linguists, speech scientists, psychologists and educators from Japan, Taiwan, Hong Kong, China, Thailand, Indonesia and Mongolia....
Aiming at the positioning problem of Ad-Hoc networks of sensors node location, a beacon selected localization algorithm (BSLA) is proposed in this paper. The proposed method considers sufficiently both the topology relationship among beacons and the topology relationship between beacon nodes and unknown nodes. We introduce the concept of collinearity and apply it into the localization of the multihop...
The problem of delay-range-dependent robust Hinfin control for uncertain systems with time-varying delays and parameter uncertainties is investigated in this paper. The time delay is assumed to be a time-varying continuous function belonging to a given range. By introducing some free weighting matrices and by exploiting a novel Lyapunov-Krasovskii functional, which includes the information of the...
The traditional model reference adaptive system (MRAS) is of parallel configuration. By representing the reference model as an equivalent closed-loop subsystem, these two subsystems can share a controller virtually. An embedded structure of MRAS is thereby presented. In this paper, two approaches are developed for designing the adaptive laws. The adaptive law based on Lyapunov stability theory is...
