The biological effects of far-infrared ray (FIR) on whole organisms remain poorly understood. The aim of our study was to investigate not only the hyperthermic effect of the FIR irradiation, but also the biological effects of FIR on wound healing. To evaluate the effect of FIR on a skin wound site, the speed of full-thickness skin wound healing was compared(More)
In this paper, an efficient log authentication scheme for forensic computing is proposed. To conduct reliable forensic computing, it is required that the logs as digital evidences be verified. To verify them, digital signatures issued by authorities are needed. However, if many logging hosts connect to the server that issues the signatures, the traffic of(More)
The Standard object color spectra (SOCS) database was developed for proper evaluation of color-sensor quality of image input devices. The SOCS has been published in a ISO technical report, ISO TR 16066. A CD-ROM is attached to the ISO-TR. The CD-ROM contains more than fifty thousands spectra of objects, such as photographic materials, offset prints,(More)
Recently, wide-gamut monitors and printers have begun to appear in the market. However, there are no appropriate tools for evaluating color reproduction in such image output devices. This report describes a method to create the image data for evaluation of the wide-gamut devices. The method expands the gamut of the source image in a manner that a color in(More)
