This paper is concerned with the fixed-time consensus tracking problem for multi-AUV (autonomous underwater vehicle) systems with uncertain parameters and external disturbances. Firstly, a fixed-time terminal sliding mode is proposed, which can avoid the singularity problem. Then, a continuous distributed...

This study proposes a method of body dynamics analysis for larval zebrafish incorporating a viscoelastic body model and a fluidic environment model to support the study of development mechanisms in motion generation. The results showed that the estimated fluid drag coefficients enabled the body dynamics...

Improvement of the work efficiency is demanded by aging and reducing of the working population in the construction field, so that some automation technologies are applied to construction equipment, such as bulldozers and excavators. However, not only the automation technologies but also expert skills...

In the construction field, the improvement of the work efficiency is one of important problems. However, the work efficiency using construction equipment depends on their operation skills. Thus, in order to increase the work efficiency, the operation skill is required to be quantitatively evaluated....

This paper considers robust containment control problem for uncertain multi-agent systems with inherent nonlinear dynamics. A distributed protocol is proposed using local delayed state information, and then the original problem is converted into an H_∞ control problem by defining an appropriate controlled...

In this study, the aim is to construct a "teacher-student model" for optimal skill acquisition. To support the optimal skill acquisition, modeling and estimation of an individual learning process are very important. The first-order system with time delay is introduced as an individual learning process...

In this study, we propose a system that provides tourist information and obtains trends of visiting tourists using beacons and cloud service. As part of our research, we are working on the promotion of local area tourism in cooperation with a local community. A low energy Bluetooth device is used as...

Aiming at developing high power efficiency system for quadrotor vehicle during height keeping and long distance flight, a quadrotor vehicle with adaptive wing is proposed. Angle of the wing respect to flying direction can be adjusted adaptively according to flying speed, to reduce energy expenditure...

The omni-directional mobile robot with multi DOF, because the operation posture and operation accuracy of the manipulator can be better controlled in a narrow or crowded workplace compared with the general manipulator, is getting more interested in practical applications. The present problem is to improve...

Although kabuki is a genre of, so to speak, traditional performing arts, it also has many of the characteristics of a contemporary genre, including such various elements as narrative, drama, dance, and music. This analysis and study will contribute to the design and development of studies on digital-narrative...

Several studies have proposed a concept called "informational narratology" or "information narratology." In this paper, we integrate narratological studies, including narratology and various literary theories, into information technologies, such as artificial intelligence and cognitive science, in order...

In this paper, we present our modification experience of making a UAV watertight and floatable. Then we present several experiments on taking pictures considering ocean monitoring in the sea near our campus. The watertight experiments are done from our school’s pier. In these experiments, we repeated...

Recent years, data mining techniques have been developed for extracting rules from big data. However, there are some problems to be considered, for example, it is difficult to judge which rules are important and which are not important; and even in simple classification problems with the small number...

A piston finger technique (PFT) was developed for restoring the motor function of chronic plegic fingers, with good treatment outcomes, including reduced spasticity and improved muscle shortening. Before developing a piston finger device (PFD) simulating the PFT, we analyzed the PFT by using a motion...

RoboCup is a competition designed to promote the research related to Artificial Intelligence (AI). We have also organized a RoboCup soccer team "Hibikino-Musashi" and work on one of AI research topics, co-operated behavior control system using multiple autonomous mobile robots. In order to realize co-operated...

Enhancing efficiency is a critical objective of corporate management. While numerous approaches to measure efficiency have been devised, this manuscript suggests a new method referred to as dynamic network-based Data Envelopment Analysis (DEA) as a more advanced procedure for examining transaction priorities...
