Wearable ECG Monitoring and Alerting Platform : Focusing on ST Segment Detection
FUJITA,Nobuaki;KATSUMATA,Erina;SATO,Akira;KAWARASAKI,Masatoshi
IEICE technical report. MICT, Healthcare and medical information communication technology   114(419) 55-60   Jan 2015
We are developing the "Wearable Heart Disease Monitoring and Alarting System (iHeart)" and carrying out demonstration experiment. In iHeart, a patient mounts the wearable ECG sensor for constant ECG monitoring and, when it detects an abnormality, ...

Heart disease has the second highest mortality rate in Japan. In particular, the ischemic heart disease such as the myocardial infarction and the heart failure requires emergency treatment. Although its symptoms emerge as an elevation or depressio...
Residual Traffic Based Task Scheduling in Hadoop
KAWARASAKI,Masatoshi;TANAKA,Daichi
CLOUD COMPUTING 2015 : The Sixth International Conference on Cloud Computing, GRIDs, and Virtualization   94-102   Mar 2015   [Refereed]
In Hadoop job processing, it is reported that a large amount of data transfer significantly influences job performance. In this paper, we clarify that the cause of performance deterioration in the CPU (Central Processing Unit) heterogeneous enviro...

IEICE Transactions on Information and Systems   E98-D(7) 1275-1285   Jul 2015   [Refereed]
MapReduce and its open software implementation Hadoop are now widely deployed for big data analysis. As MapReduce runs over a cluster of massive machines, data transfer often becomes a bottleneck in job processing. In this paper, we explore the in...
Data Transfer Aware Scheduler for Hadoop
WATANABE,Hyuma;KAWARASAKI,Masatoshi
IEICE technical report. Information networks   113(473) 175-180   Feb 2014
Data transfer time occupies large amount of Hadoop job processing time. In this paper, we propose new Hadoop task scheduling algorithms which take account of network I/O and HDD I/O usage rate of task trackers to shorten the time for data transfer...
