Kodaira, Japan

Musashino Art University is a university in Kodaira, western Tokyo, founded in 1962 and having roots going back to 1929. Teikoku Art School was founded in 1929; in 1948 it became Musashino Art School , and in 1962 it became Musashino Art University. This is known as one of the leading art universities in Japan.From its start, the university taught fine art and industrial design; it later added architecture, fashion, and other fields.MAU has exchange agreements with universities in other countries. It has a graduate school that awards master's degrees and doctorates. Wikipedia.

We study the relation between strong and extreme geomagnetic storms and solar cycle characteristics. The analysis uses an extensive geomagnetic index AA data set spanning over 150 yr complemented by the Kakioka magnetometer recordings. We apply Pearson correlation statistics and estimate the significance of the correlation with a bootstrapping technique. We show that the correlation between the storm occurrence and the strength of the solar cycle decreases from a clear positive correlation with increasing storm magnitude toward a negligible relationship. Hence, the quieter Sun can also launch superstorms that may lead to significant societal and economic impact. Our results show that while weaker storms occur most frequently in the declining phase, the stronger storms have the tendency to occur near solar maximum. Our analysis suggests that the most extreme solar eruptions do not have a direct connection between the solar large-scale dynamo-generated magnetic field, but are rather associated with smaller-scale dynamo and resulting turbulent magnetic fields. The phase distributions of sunspots and storms becoming increasingly in phase with increasing storm strength, on the other hand, may indicate that the extreme storms are related to the toroidal component of the solar large-scale field. © 2015.

The filter simulates 'Shinhanga,' multi-colored woodblock print, which was once popular in Japan around one hundred years ago. We expect that the filter sheds light again on this fascinating art style. The filter follows three steps to simulate contour lines and gradation, which characterize 'Shinhanga'; The filter extracts contour lines based on hue of an original image, then determines the direction of color gradient in each region either vertically or horizontally, based on the amount and the direction of variation of hue in each region. We improved the contour lines and gradation process from the previous filter to broaden its applicability and conducted an experiment to assess it. The result suggests that the filter has less dependency to the types of images comparing to our previously proposed method. © 2013 IEEE. Source

A new stereoscopic measurement technique is developed to obtain an all-sky altitude map of aurora using two ground-based digital single-lens reflex (DSLR) cameras. Two identical full-color all-sky cameras were set with an 8 km separation across the Chatanika area in Alaska (Poker Flat Research Range and Aurora Borealis Lodge) to find localized emission height with the maximum correlation of the apparent patterns in the localized pixels applying a method of the geographical coordinate transform. It is found that a typical ray structure of discrete aurora shows the broad altitude distribution above 100 km, while a typical patchy structure of pulsating aurora shows the narrow altitude distribution of less than 100 km. Because of its portability and low cost of the DSLR camera systems, the new technique may open a unique opportunity not only for scientists but also for night-sky photographers to complementarily attend the aurora science to potentially form a dense observation network. © Author(s) 2013.

Lion Shoes is an art installation, which was created for the 21 21 DESIGN SIGHT Exhibition 'COLOR-HUNTING' directed by Dai Fujiwara. This exhibition promoted a method to bring the power of color into the design process. Lion Shoes was designed by Fujiwara and the shoe manufacturer Camper based on the colors of lions, which were collected in Africa. Our team developed a system of mobile robots that moved the Lion Shoes on a table. We made the robots react to visitors and we observed how visitors viewed the exhibit. Although the results indicated that the reactive behaviors should have been obvious, we found that some visitors made emotional responses to the shoe robots. © 2014 IEEE. Source

Auroral microphysics still remains partly unexplored. Cutting-edge ground-based optical observations using scientific complementary metal-oxide semiconductor (sCMOS) cameras recently enabled us to observe the fine-scale morphology of bright aurora at magnetic zenith for a variety of rapidly varying features for long uninterrupted periods. We report two interesting examples of combinations of fine-scale rapidly varying auroral features as observed by the sCMOS cameras installed at Poker Flat Research Range (PFRR), Alaska, in February 2014. The first example shows that flickering rays and pulsating modulation simultaneously appeared at the middle of a surge in the pre-midnight sector. The second example shows localized flickering aurora associated with growing eddies at the poleward edge of an arc in the midnight sector. © 2015 Kataoka et al.; licensee Springer. Source
