Prediction of inner pinch for a supercritical CO2 heat exchanger using artificial neural network and evaluation of its impact on cycle design   The power system using CO2 in the supercritical phase has attracted attention in recent years due to its high efficiency and small component size. Supercritical CO2 shows a dramatic change in thermodynamic properties near the critical point; therefore,...

Ventilated Supercavitation: A technology for reducing the drag force of a moving underwater object   A new technology was introduced that significantly reduces the drag force of a moving body by using the supercavitation phenomenon.   Article | Spring 2019     When a body moves in air, the drag force is lower than that of the same body moving in water. Therefore, during its motion, if a b...

Coatable Electronic Skin: E-skin can be coated on three-dimensional surfaces An electronic skin was created that can be coated on three-dimensional surfaces and can distinguish mechanical stimuli.   Article | Spring 2019     Recently, electronic skin (e-skin) research has been actively carried out to mimic human-level tactile sense for various applications. However, previously reported e-skins...

Crash to Not Crash : Learn to identify dangerous vehicles using a simulator   A deep-learning-based vehicle collision prediction system was developed using data collected from a video game. The proposed system outperforms existing systems relying on simple rules by identifying various accident-related factors (such as nearby vehicles’ wheel angles, orientations, velocities) and is expected to ...

Recombinant Escherichia coli as a biofactory for the biosynthesis of diverse nanomaterials A recombinant E. coli strain that biosynthesizes 60 different nanomaterials covering 35 elements was developed. A strategy using the recombinant E. coli strain provides a new platform for manufacturing diverse industrial nanomaterials in an environmentally-friendly manner.   Article | Spring 2019   &...

Simultaneous magnetic resonance arteriography and venography A new method for simultaneous acquisition of a magnetic resonance (MR) arteriogram and an MR venogram is developed. The approach provides clinicians with diverse vascular information within a short scan time, which is crucial for clinical diagnosis of patients, especially under time-sensitive conditions such as stroke.   Article | Fall 2019 &n...
