Numerous studies have reported on the healing powers of plants and nature, but there have not been so many instances of experimental research. In particular, there are very few psychological and physiological studies using tactile stimuli. This study examines the psychological and physiological effects of touching plant foliage by using an evaluation(More)
Numerical studies of lattice eld theories have developed signi cantly in parallel with the development of computers during the past decade. Of particular importance in this regard has been the construction of dedicated QCD computers (see Table 1 and for earlier reviews see Ref.[1]) and the move of commercial vendors toward parallel computers in recent(More)
Photography gives us pleasures in many ways. Shooting a photo itself is fun. It is also interesting to express one's emotion by photography. You can show pictures to friends and share memories. We focus on shooting and consider how to enhance a pleasure of shooting. One of the interesting things about shooting photos is storing information of a scene and(More)
The CP-PACS project is a five year plan, which formally started in April 1992 and has been completed in March 1997, to develop a massively parallel computer for carrying out research in computational physics with primary emphasis on lattice QCD. The initial version of the CP-PACS computer with a theoretical peak speed of 307 GFLOPS with 1024 processors was(More)
The aim of the CP-PACS project was to develop a massively parallel computer for performing numerical research in computational physics with primary emphasis on lattice QCD. The CP-PACS computer with a peak speed of 614 GFLOPS with 2048 processors was completed in September 1996, and has been in full operation since October 1996. We present an overview of(More)
Conventional interaction researches deal with relatively small spaces with physical proximity or completely distant spaces without physical proximity. However, there is an intermediate range of them. The distance to a target for interaction is longer than physical proximity but the target can be seen in a view. Such situations occur in sport stadiums,(More)
Finding a good subject or scenery is a key to take a good picture. Usually a photographer walks around to look for them, but sometimes he/she doesn't want to do and instead he/she wants to do something more interesting. In such a case, it would be good to have an assistant system which autonomously looks for shooting locations and takes you there at your(More)
