Analysis precision of buck ratio and power efficiency in buck DC-DC converter circuit is improved by proposing adaptive equivalent circuit of flywheel diode in the circuit. In conventional analysis, the flywheel diode wa ... more
A new radio system that deterministically uses reflection waves is proposed. This system transfers data on the rotating polarization wave (RPW) which rotates the polarization at enough lower frequency than that of propag ... more
Maintenance support systems (MSS) monitoring conditions of facilities are indispensable for condition-based maintenance (CBM). A sensor network is used to acquire maintenance data in the MSS, and installation of the sens ... more
This paper proposes a robust compensator design for sinusoidal inverter based on the design methodology named Dual Model Matching and numerical optimization. This proposed method can simply design a controller which ensu ... more
The distance to a target is basic information in many engineering fields. As is generally known, the distance is typically estimated using time-of-flight (TOF) between transmitted and reflected impulses. However, it cann ... more
Finger-spelled sign language recognition is one of hand sign recognition tasks and one of most challenging ones in some research area such as computer vision and human computer interaction. In this research, we especiall ... more
In Real Time Spectral Analysis, Simultaneous Improvement of Both Time Resolution and Frequency Resolution by the Multi-stage Analysis, and Signal Reconstruction
In recent years, analytical method in which the length of time-window for time-localization can be established optionally was shown by the authors. If you decide the time-window width which is in inverse proportion to th ... more
In pronunciation training, we learn to properly control properly our articulator for correct pronunciation. Therefore, the pronunciation training system needs to build effective visual support for the trainee. In this re ... more
This paper proposes a new approach to solve Chance Constrained Problems (CCPs) efficiently. Specifically, the probabilistic constraint in CCP can be evaluated directly if the Cumulative Distribution Function (CDF) of unc ... more
In recent years, presentation with computer is important as a social skill to transfer knowledge and information, but presentation practice is depending on the know-how, such as instructor's experiences or textbooks. We ... more
In semiconductor device manufacturing process, it is necessary to measure overlay error between integrated layers. As semiconductor process design rules continue to shrink, small overlay error comes to lead to the fatal ... more
We develop a new optimization method for the daily water supply pump operation scheduling using the branch and bound method. In the method, we define a search tree as a trinary tree in which the nodes are the number of o ... more
