We have implemented a high-definition 3D audiovisual reproduction system based on higher-order ambisonics (HOA) using a surrounding-157-loudspeaker array combined with a 3D projection display to reproduce information with high sense-of-presence. In this report, we introduce the system overview as well as an investigation to realize good system synchronization, which we are keenly devoted to. Results...
InAs/InP QDs broadband LED more than 450 nm spectrum width was successfully demonstrated. The broadband spectrum was obtained from the height controlled double-cap procedure and strain controlled buffer layer fabricated by the selective MOVPE technique.
In this paper we present a simple but powerful one-step growth method of ultra-long vertically aligned multi-walled CNT (MWNT) array, and its possible applications. Our growth method requires no additional process for catalyst thin film (pre-deposition), and only requires iron chloride powder and acetylene gas. We also present the results of electrical properties of MWNT array, such as electrical...
More than 400 nm spectrum width LED was obtained in the InAs QDs array waveguide using height changed QDs during double-cap procedure and strain controlled buffer in 3 layered QDs.
When the movement of an observer through a three-dimensional (3D) space is simulated via a multimodal display system, the synchrony of cues from different sensory modalities can help or hinder the creation of illusions of self motion. Stereoscopic stimuli provide particularly strong cues to self motion, through both binocular and motion disparity, but in the absence of these visual cues, movement...
Recently, wireless ad hoc communication systems have been receiving attention. In order to improve the efficiency of such networks, researchers have tried to apply adaptive array antennas (AAA) for interference cancellation in the space domain. In this paper, we propose a new method based on a new concept, called cross-degree of freedom (CDOF), for the application of AAA to ad hoc communications....
Two major objectives of a binaural microphone array system are reducing background noise and retaining interaural relationships, for example, ILD and ITD. Hence, a new adaptive microphone array signal processing based on a weighted least squares algorithm for binaural hearing is proposed in this paper. Instead of Lagrange's method of indetenninant coefficients, which is often used in conventional...
