Mechanical systems or robots to assist landmine detection are expected to greatly improve quality of humanitarian demining tasks. These new systems could provide: i) safer operation; ii) advanced methods for automatic target recognition and discrimination; iii) consistent performance with less influence of “human-factors”; iv) better detection performance,(More)

The distribution model of wavefront aberrations, which takes on a significant role in the designs and alignments of imaging optical systems without vignetting, is newly presented. This model decomposes the complicated distributions into the characteristic components, which clarifies the alignment criteria. For the actual alignments, only small displacements(More)
As technology is growing there is a considerable demand on machine interface to the controlling system. Robotics is an era where mechanical structures are powered by interfacing personal computers with the improved software tools. Hyperlink is a standalone program to interact with the devices remotely interfaced with the personal computers. Wireless(More)
et al6), and VEZEY et al.7) have been reported the efficacy of SCP on various strains of coccidia. REID et al.8) have shown that SCP was coccidiocidal rather than coccidiostatic in its action. Moreover, in vivo the drug has been shown to be active against staphvlococci in mice and against Salmonella gallinarum and Pasterella in chicks by GABRIEL and(More)
We surveyed interpretation of the ICH guidelines concerning reproductive toxicology. Valid responses were obtained from Japan (JPN), Europe (EUR) and the U.S. The results obtained were compared to those at the time of a previous survey targeted at JPN facilities in 1995-1996 as well as compared among all three regions. Compared to the previous survey in(More)
To measure the use of alternatives to in vivo mammalian toxicity studies during drug research and development, the Japan Pharmaceutical Manufacturers Association (JPMA) distributed a questionnaire to its 99 member companies, of which 85 responded and 50 (59%) of them had some experiences in using alternatives to in vivo mammalian toxicity studies. The(More)
The parametric camera model is newly presented in order to calibrate rotationally nonsymmetric and noncentral cameras. This model assumes cameras designed rotationally symmetric and containing manufacturing errors. For this purpose, the general expression of the principal rays, which are equivalent to the backprojection lines corresponding to the image(More)
