Red tides off the Japanese coast caused serious damages to aquaculture industries in every year (Honjo 1994). To reduce fisheries damage due to red tide, it is important to inform aquaculturist of red tides in short-t...

We are developing a rhythm practice support system with onset detection. The system produces guiding metronome sounds and processes the performed sound to detect onsets in real time. Spectral flux and dynamic thresholding are used to find onsets in the audio signal. We made three types of prototype display for the system; a survey of user display preference was conducted. An evaluation of the accuracy of the onset detection is also provided.
In this study, we clarified relationship between the interfacial average stress and the non-dimensional intensity of stress singularity for aluminum bonded joints. In experiments, delamination tests were carried out b...

The main contribution of this paper consists in solving the problem of fault tolerant control (FTC) for linear parameter varying (LPV) systems subject to actuator saturation and fault detection and isolation (FDI) delays. The FTC is based on virtual actuators that reconfigure the faulty plant to maintain the stability and to avoid the saturation of the actuators. On the other hand, a design methodology that provides the nominal output-feedback controller, which maximizes the tolerated delay between the fault occurrence and its isolation, is developed. The design process consists in finding the optimal feasible solution to a finite set of linear matrix inequalities (LMIs). Finally, an example is used to illustrate the theoretical results.
Major construction and initial-phase operation of a second-generation gravitational-wave detector KAGRA has been completed. The entire 3-km detector is installed underground in a mine in order to be isolated from back...

Motivated by the fact that bounded variation (often discontinuous) functions frequently appear when studying integral equations that describe physical phenomena, we focus on the existence of bounded variation solutions for Urysohn integral measure driven equations. Due to numerous applications of Urysohn integral equations in various domains, problems of this kind have been extensively studied in literature, under more restrictive assumptions. Our approach concerns the framework of Kurzweil-Stieltjes integration, which allows the occurrence of high oscillatory features on the right hand side of the equation. A discussion about interesting consequences of our main result (given by particular cases of the measure driving the equation) is presented. Finally, we show the generality of our results by investigating two examples of impulsive type problems (from both theoretical and numerical perspective) and giving an application in electronics industry concerning polarization properties of ferroelectric materials.
