Detection of number of uncorrelated and coherent narrowband signals with L-shaped sensor array
This paper deals with the problem of estimating the number of mixed narrowband signals of uncorrelated and coherent signals impinging on the L-shaped sensor array, which is structured by two uniform linear arrays (ULAs). Since the total num...
Design of ball-cage based miniature stroke for integration in a flexible actuator with thrust wire
Robotic technology is used widely today because of their advantages to support human operator. Robot systems have been used, not only for industrial processes, but also for a wide range of applications, such as minimally invasive surgery. T...
A method for estimation of operational torque with utilizing a hysteresis model
Along with the population aging, human interactive robots are expected to be introduced in our daily lives especially in developed countries. For such robots, bilateral control is widely researched as a technique for transmission of both po...
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...
