Emission of terahertz radiation is observed when a single layer graphene on a glass slide is excited with femtosecond near-infrared laser pulses. Furthermore, we can enhance the amplitude of terahertz emission by surface plasmon resonance excitation on a thin gold film in the Kretschmann geometry.
Currently, brain-computer interface experiments have progressed actively, but in the repeated experiments, variation of the electrode location used causes accuracy of result to decrease. The aim of this study was to compare and evaluate methods of feature extraction for electrode location robustness in BCI to prevent accuracy from decreasing. Features were extracted by using power spectrum density,...
In this paper, a technique for combination of fast moving least square reproducing kernel method (FMLSRKM) which is a kind of meshfree methods and finite element method (FEM). Point collocation scheme is used for FMSLRKM. Combined method is tested using 2D electrostatic problem.
This paper proposes a new approach named electrocorticographic (ECoG) signals characteristics driven approach (ESCDA) to precisely estimate focal sources. The ESCDA is driven by the unique spatio-temporal-spectral characteristics of brain activity provided by ECoG signals. From feasibility studies, it is concluded that the ESCDA is a reasonable and robust technique to enhance the performance of focal...
3-dimensional (3D) model retrieval is one of an important research fields to retrieve a query for models with matching shape from the database. This paper proposes a new shape descriptor using histograms of 2D slice images to cut in the x-, y-, and z-coordinates, respectively for solving the similarity measure from 3D models. Our approach is to compute the slices of 3D model for the x-, y-, and z-coordinates,...
We propose a new vehicle tracking system which can detect and monitor vehicles as they break traffic lane rules. Our proposed tracking scheme is based on characteristics of both traffic scene and vehicle. These include: background information, local position, and the size of a moving vehicle. The initial size and position of the vehicle are obtained using a 4-directional contour tracking method. The...
In this paper, we describe AR squash game, which is a squash-style game based on AR (augmented reality) technique. We made this game using AR technique to estimate geometric information of images taken from a CCD camera. A CCD camera takes real-time images of a room formed by some number of walls, and the geometric information of the image is estimated using markers attached on the walls. By the geometric...
From the recent trends in the demand for buildings, the customers increasingly prefer high-rise buildings. This reinforces the fact the general contractors focus on the cut-down of costs to reduce the term of works in construction. As this effort, the ASCI (automation system for curtain-wall installation) which combined with a multi-D.O.F. manipulator to a mini-excavator was developed and applied...
