Variety in Big Data means we have a wide range of data types and sources: e.g. File systems and database systems co-exist for decades as two popular data-accessing interfaces. This work is to unify these two interfaces by presenting a Data Interface All-iN-A-place (DIANA). The first challenge lies in distinguishing structured and un-structured data and diverting them to different underlying platforms...
The imbalance of autonomic nervous system (ANS) has a close relationship to cardiac mortality. The noninvasive assessment of ANS is of great importance and remains challenging. A new method, characterizing the consistency of short-term nonlinear indexes of heart rate variability (HRV) and QT variability (QTV), is proposed and validated. Holter records from two databases in Telemetric and Holter ECG...
The purpose of this study is to investigate the behavior of autonomic nervous system (ANS), reflected by short-term variability (STV), in the hemodialysis patients with high risk for cardiac arrhythmias and sudden cardiac death. Comparison was performed with normal people. The data were provided by THEW (database ESRD and Normal). STV of RR intervals (STVRR) and QT intervals (STVQT) as well as the...
In order to measure lightning damage risk, this article has introduced the concept of regional lightning risk assessment to make some pre-assessment of the extent of danger and damage. Considering the characteristic of multi-factor, fuzziness and uncertainty, this article applies the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation to provide a hierarchical model of the regional...
This article introduced how to use the idea of fuzzy evaluation to study the problem of regional lightning risk assessment. The fuzzy evaluating model is constructed by influential factors of lightning risk assessment. At the same time, the rules and the measurements of the regional lightning risk assessment based on fuzzy evaluation are presented. Based on the analysis of influential factors and...
