Wireless body area networks (WBANs) are emerging as important networks, applicable in various fields. This paper surveys the WBANs that are designed for applications in healthcare. We present a comprehensive survey consisting of stand-alone sections focusing on important aspects of WBANs. We examine the following: monitoring and sensing, power efficient protocols, system architectures, routing ...

We present a method to automatically register 2D cerebral digital subtraction angiography (DSA) images to 3D-DSA volumes. The method can be used for validation of flow simulation results and surgery planning. The algorithm was tested on clinical studies of six patients.

This paper describes the approaches of sentimental score prediction in the NTOU DSA system participating in DSAP this year. The modules to predict scores for words are adapted from our system last year. The approach to predict scores for phrases is keyword-based machine learning method. The performance of our system is good in predicting scores of phrases.

Despite the importance of sustained use of healthcare information systems, research on the continuous use of these systems is scanty, especially for clinical decision support systems. Moreover, there is an apparent gap between information systems and healthcare research approaches in studying use. We address these gaps by creating a comprehensive model based on the composite attitude-behavior m...

The Dynamic Spectrum Access (DSA) paradigm based on the Cognitive Radio (CR) technology has emerged as a promising solution to conciliate the existing conflicts between spectrum demand growth and current spectrum underutilization without changes to the existing legacy wireless systems. The basic underlying idea of DSA/CR is to allow unlicensed users to access in an opportunistic and non-interfe...

In the paper we detail the reduced form or hazard rate method of pricing credit default swaps, which is a market standard. We then show exactly how the ISDA standard CDS model works, and how it can be independently implemented. Particular attention is paid to the accrual on default formula: We show that the original formula in the standard model is slightly wrong, but more importantly the propo...

Several current healthcare standards support semantic interoperability. These standards are far to be completely adopted in health information system development, however. The objective of this paper is to provide a method and necessary tooling for reusing healthcare standards by exploiting the extensibility mechanisms of UML, by that way supporting the development of semantically interoperable...

There is a critical gap in our nation's ability to accurately measure and manage the quality of medical care. A robust healthcare quality information system (HQIS) has the potential to address this deficiency through the capture, codification, and analysis of information about patient treatments and related outcomes. Because non-technical issues often present the greatest challenges, this paper...

Social media such as We Chat provide new ways of communicating healthcare information and knowledge. Many healthcare institutions leverage We Chat public platform to disseminate healthcare knowledge in the hope of attracting public attention. It is critical for them to build a comprehensive understanding of the factors affecting WeChat users’ willingness to diffuse healthcare knowledge, an issu...
