A major computational challenge for a multiscale modeling is the coupling of disparate length and timescales between molecular mechanics and macroscopic transport, spanning the spatial and temporal scales characterizing the complex processes taking place in flow induced blood clotting. Flow and pressure effects on a cell like a platelet can be well(More)
We analyzed an acceleration pattern during natural walking and walking hampered by wearing weights to predict falls. These two types of walking could be distinguished with a peak at the half of the principal frequency of the gait in anterior movement. We measured walking while wearing each individual hampering weight and then analyzed. The peak was bigger(More)
When the International Space Station (ISS) is completed and starts its operation, crew members will be stationed for three months or more in orbit aboard the ISS. As they stay longer in the space environment, "habitability" for them will become most important in the design of the interior space. One of the problems about habitability in a zero gravity (0 G)(More)
Advancement of computed tomography (CT) technology enables us to develop a complete patient-specific geometric model of pulmonary airways. Computational fluid dynamics (CFD) analysis using the patient-specific model should become an essential tool in the future diagnosis. One of the difficulties in pulmonary airflow simulation is that pulmonary airways are(More)
Electroencephalograph (EEG) recordings during right and left hand motor imagery can be used to move a cursor to a target on a computer screen (such system is called BCI). Recently, we have proposed the detection method of Error Potential in order to add the fail safe function to BCI system. In this paper, feature extraction method based on morphological(More)
