We study a generalized version of reversal bounded Turing machines where, apart from several tapes on which the number of head reversals is bounded by r(n), there are several further tapes on which head reversals remain unrestricted, but size is bounded by s(n) (where n denotes the input length). Recently [9,10], such machines were introduced as a formalization of a computation model that restr...

Demands for realization of communications with a high sense of presence have become great. For such communications, it is important acoustically to capture and transmit comprehensive sound space information of remote places to a local site. The authors developed an avatar robot, which was developed as a simplified version of TeleHead proposed by Toshima et al. The robot’s head moves synchronous...

The impression of space and perception distance may be different in real space, 3D on the flat display (DP space), immersive head-mounted (HMD space). In this study, mean value standard deviation were calculated verified based data obtained from experiment. difference between DP HMD for is described. results showed differences perceived and, psychological evaluations, openness presence object.

Introduction Post Gadolinium MR head and neck examinations remain challenging due to the need for a large anatomic coverage in minimum acquisition time. For cranial nerves and skull base investigations, 3D acquisitions are very useful not only to better visualize and analyze the cranial nerves but also to provide large head and neck coverage of wide-spread or multi-focal pathology. Until recent...
