I am deeply involved in the projects listed here. The projects are sorted in reverse chronological order.
This research focuses on a distributed software design pattern and protocol to guarantee the safety of the subject even the communication fail between the wireless connected devices on a Cyber-Physical Environment. For example, in the wireless medical environment, devices can be conflicted due to communication fail or packet lost, which may, further, threaten the patient’s health.

Open Information System for Disaster Management (OpenISDM) is a thematic project of Academia Sinica, Taiwan. Its goal is to develop an open framework for systems that provide data and information needed to support decisions and operations during disaster preparedness, response and recovery, and research and planning in disaster reduction.
I collaborate with Prof. Jane W.S. Liu in Sub-Project: Virtual Repository (VR) from Insititute of Information Science, Academia Sinica. I also collaborate with both Prof. Jane W.S. Liu and Prof. Chi-Sheng (Daniel) Shih in Sub-Project: Open Information Gateway (OIGY).
In the VR project, I am in charge of building the VR framework as a repository source and a collection of tools to assist develop semantic web based disaster preparedness and response systems. The first tool I involved is to construct legacy data to linked data. The focus of this work is making the translated linked data connected to existing ontologies and let the newly created URI can be linked, modified and constructed by domain experts. Hence, the newly translated data is alive and connected to the semantic web. The second tool I developed is named Intelligent Active Storage Service, it is a distributed polling service to transform the passive source such as weather observation sources to active push sources. This tool saves the developer’s efforts to monitor individual sources and integrate multiple sources into their information system. I was deeply involved in the VR development from problem definition and modeling to software construction. The efforts are published at IEEE SOCA-RITMAN 2012 and at WIT Disaster Management 2013.
In OIGY project, I was involved building a Pub/Sub message delivery service for delivering prioritized alert message on the open network. This service allows prioritizing alert message according to its urgency and severity. The delivering service provides QoS according to priorities of messages. The work is published at IEEE Cyber-Physical System, Network and Application (CPSNA) conference 2013 as well as IEEE Innovative Mobile and Internet Services in Ubiquitous Computing (IMIS) conference 2013.
Although lots of medication auxiliary devices have been developed and used for assisting patients to take medication, they do not guarantee the patients are taking the right medication with the right dosage at the right time. For example, they rely on patients to read the prescriptions and schedule the medication. They do not check medication interactions. When patients are late to take medication, they do not know what to do. To solve this kind of problems, we developed an Intelligent Medication Use Solution called iMUS.
iMUS is designed for users to take medication correctly and safely, especially for outpatients without professional supervision. Its functions include storing and automatically locking drugs, saving medication historical records, scheduling medication, avoiding medication misuse and instructing medication dosage.
I collaborate with Prof. Pei-Hsuan Tsai of the Institute of Manufacturing Information and Systems, National Cheng Kung University. In this project, I design the iMUS device from the industrial design of the prototype, embedded system to software architecture. iMUS is demonstrated at the 2012 IEEE Biomedical Circuits and Systems Conference (BioCAS). A demonstration video is available on YouTube.

Topic: Head-to-Head: Which is the Better Cloud Platform for Early Stage Start-up? Docker versus OpenStack
We design a decison tree for choosing between OpenStack and Docker cloud platforms. We use YCSB key-value store benchmark to evalute the performance of MongoDB and Cassandra on both cloud platforms. Course website.

Timestamp Log Parser (TLP) is deisgned to pre-process the log data. Developers can use the output file for other numerical analyis software such as Excel. TLP is for calcuating the time consuming between each stage in software components. For example, a messages oriented middleware (MOM) is using to deliver the message to another software component. We want to evaluate how much time does a message spend between each processing stage of software components. We use TLP in pre-processing the performance data mentioned in the paper at IEEE CPSNA 2013. Please visit our project at GitHub for more detail and documentation.
