How to Ask Questions “Wisely” to People to Maximize Information?   Crowdsourcing systems have become a popular platform to label and classify items in large-scale databases. A team led by Prof. Hye Won Chung has discovered an efficient way of asking questions to human workers by using a technique from information theory.   Article | Special Issue     Crowdsourcing systems ...

How to Rapidly Modify and Download Huge 3D Meshes   Progressive compression is a multi-resolution scheme for sending large 3D meshes in a network environment. However, if 3D meshes are deformed, it takes too much time to compress them from scratch. Wavelet-based fast recompression speeds up the compression time by up to 33 times.   Article | Special Issue     Imagine that users are do...

A Novel Approach to Reduce Usage of Precious Catalysts for Hydrogen Production   Water electrolysis can efficiently store surplus electricity in the form of hydrogen, a clean future fuel. However, use of precious catalysts limits the dissemination of method of energy storage. This study presents TiO2-MoOx oxide as a support for iridium (Ir) nanoparticle catalyst. By introducing the TiO2-MoOx support...

Project Black Box: Learning and predicting the economy from satellite imagery   High-resolution daytime satellite imagery contains rich and sophisticated geospatial information of faraway regions. This highlight introduces remarkable projects led by an interdisciplinary team of researchers from computer science, economics, and geography, developing deep learning models to quantify fine-grained economic activi...

Interpreting urban mobility big data with graph representation for air and surface transportation   The inundation of urban big data has engendered unprecedented opportunity for a future mobility revolution. Researchers at the TRUE Lab are tackling the challenge to effectively capture the spatial and temporal fluctuations of mobility data in graph representation, both for the air and surface transportation. I...

High Strength and Fatigue Resistant Metal-Graphene Nanolayered Composite   Graphene, when alternated with metal thin films in the form of metal-graphene nanolayered composite, can effectively hinder dislocation propagation to result in ultra high strength and fatigue resistant composite material. Metal-graphene nanolayered composite is, therefore, expected to have enhanced reliability when used as electrodes ...
