Transparency of centralized controller based bilateral control
This paper analyzes the transparency of a centralized controller based bilateral control system with communication delay. Some previous researches show validity of the centralized controller by experiments. However, the effectiveness has no...
Frequency-domain analysis of wave variable based teleoperation and its equivalent implementation
The wave variable based teleoperation has been analyzed and designed in time domain since it came into being. However, past researches paid little attention to the frequency domain characteristics of this method. Therefore, this study analy...
Energy spectrum and anisotropic g-factor of elliptic quantum dot
We theoretically examine the energy spectrum and anisotropic g-factor of an elliptic quantum dot in the presence of strong spin-orbit (SO) interaction. The Kramers' degeneracy of energy levels in the quantum dot is lifted by applying a magn...
Superfluid/ferromagnet/superfluid-junction and π-phase in a superfluid Fermi gas at finite temperatures
We investigate the stability of π-phase in a polarized superfluid Fermi gas (N<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">↑</sub> >; N<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" x...
Theory of photoemission-type experiment in the BCS-BEC crossover regime of a superfluid Fermi gas
We theoretically investigate the recent photoemission-type experiment on <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">40</sup>K Fermi gases done by JILA group. Including pairing fluctuations...
Pseudogap phenomenon in an ultracold Fermi gas with a p-wave interaction
We investigate fluctuation effects in a single-component ultracold Fermi gas with a p-wave interaction. Within the framework of a strong-coupling T-matrix theory, we calculate the single-particle density of states (DOS) at the superfluid ph...
Hybrid pump-wavelength configuration for optical packet switch with parametric wavelength converters
This paper proposes an optical packet switch (OPS) with parametric wavelength converters (PWCs) that combines the advantages of static pump wavelength assignment (SPA) switch and dynamic pump wavelength selection (DPS) switch to trade off t...
Evaluation of flexibility in hybrid WDM/TDM PONs
Introducing a WDM dimension on the top of a TDM PON system is a natural evolution to increase the capacity of an optical access network, and this can also offer additional flexibility options. Several hybrid WDM/TDM PON architectures can be...
A design method of high-availability and low-optical-loss optical aggregation network architecture
A highly-energy-efficient network using an optical aggregation network and a service cloud has been proposed to reduce the power consumption of today's Internet greatly. The optical aggregation network connects a solitary giant router to us...
A study of next generation metro-access hybrid scalable network by using PLZT ultra high speed optical wavelength selective switch
We have studied a novel optical access network with PLZT (Plomb Lanthanum Zirconate Titanate) optical switches, called ActiON (Active Optical Network), as a next generation access network to replace PON (Passive Optical Network). On the oth...
