In this paper, we present an indoor 3D positioning method for smartphones using acoustic signals. In our proposed 3D Frequency Division Multiplexing--Phase Accordance Method (3D FDM--PAM), four speakers simultaneously emit burst signals comprising two carrier waves at different frequencies to enable the rapid calculation of the position of the smartphone.(More)
This paper describes the QoS control capabilities in the new Japanese academic network, SINET3. SINET3 is a nationwide QoS-aware multi-layer network for more than 700 universities and research institutions and provides a variety of high-quality network services including packet-based QoS services and circuit-based bandwidth-on-demand services. These(More)
talking and singing robot is being developed based on the mechanical model of the human vocal system by using mechatronics and feedback control technologies. While various ways of vocal sound production have been actively studied so far, a mechanical construction of the vocal system is considered to advantageously realize natural vocalization with its fluid(More)
