Design and Development of a Real-Time Monitoring System for Multiple Lead–Acid Batteries Based on Internet of Things
(Journal article; Peer reviewed, 2017)In this paper, real-time monitoring of multiple lead-acid batteries based on Internet of things is proposed and evaluated. Our proposed system monitors and stores parameters that provide an indication of the lead acid ... -
Déjà vu - Predicting the number of players in online games through normalization of historical data
(Chapter; Peer reviewed, 2011)A key factor to delivering a good online gaming experience is to have sufficient server resources relative to the number of players online. In this work, we present a simple profiling technique which allows effective ... -
Discovering Fuzzy Association Rules from Patient's Daily Text Messages to Diagnose Melancholia
(Chapter; Peer reviewed, 2010)With the constant stress from work load and daily life people may show symptoms of melancholia. However, most people are reluctant to describe it or may not know that they already have it. In this paper a novel system ... -
Effects of common keyboard layouts on physical effort : implications for kiosks and Internet banking
(The proceedings of Unitech2010 : International Conference on Universal Technologies;, Chapter; Peer reviewed, 2010)This study investigates the effect common keyboard layouts have physical effort.
