Mitigating heat generated by hot spots inside of power electronic devices is a formidable obstacle to further increases in power density. This paper presents the first demonstration of active cooling for hot spots via jumping droplet condensation. This newly discovered phase change cooling mechanism comprises 10 to 100 μm sized droplets leaping from a cold superhydrophobic surface onto a hot GaN transistor...
Many people incorporate music into their daily lives, and the development of robots with musical awareness provides an opportunity for rich forms of human-robot interaction. Robots must, however, acquire a variety of skills before being able to participate in musical activities. In order to dance or play an instrument, for example, a robot be able to utilize substantial auditory and visual information...
The recent advance in SNP genotyping has made a significant contribution to reduction of the costs for large-scale genotyping. The development also has dramatically increased the size of the SNP genotype data. The increase of the volume of the data, however, has posed a huge obstacle to the conventional analysis techniques that are typically vulnerable to the high-dimensionality problem. To address...
Humanoid robotics development often depends on simulation and prototypes for new walking algorithms. The advantages of simulation such as low cost and risk make repeated experiments and development more straightforward. However, real world implementation can require extensive porting to move from a simulation environment to a hardware platform. This tedious task can be a huge time sink that drastically...
An interactive participant in a live musical performance requires a multitude of senses in order to perform. These senses include hearing, sight, and touch. Our long-term goal is to have our adult size humanoid robot Jaemi Hubo be an interactive participant in a live music ensemble. This work focuses on Jaemi Hubo's sense of sight as it pertains to a musical environment. Jaemi Hubo's musical awareness...
