Synchronization in coupled bifurcating neurons was studied from the view point of the selective formation of cell assembly. The bifurcating neuron is a simple chaotic neuron that exhibits chaotic inter-spike interval dynamics via the addition of sinusoidal background oscillation. In this research, we...

The stride is an important parameter in human motion analysis and has been extensively studied by many researchers. This paper focuses on smartphones that are popular in the world, regardless of the measurement environment. In previous research, the stride estimation using the acceleration sensor or...

IoT (Internet of Things) has been attracted attention, and several system data can be obtained by communication and it is stored in database. The input/output data is expected to be utilized to control systems in industries. The data-driven technique has been proposed as a way to utilize database for...

We developed a secure communication method using a discrete wavelet transform. Two users must each have a copy of the same piece of music to be able to communicate with each other. The message receiver can produce audio data similar to the sending user's speech by using our previously proposed method...

In order to reduce the complexity of traditional methods, a PCI (Proportional Complex Integral) controller is adopted to control SVG under unbalance-grid condition, which has better performance than PI controller to eliminate steady-state error to compensate nonlinear loads. Based on the •• frame, the...

In this paper, a catapult separation device equipped with guide mechanism is considered, and the corresponding dynamic model is descripted firstly. Then, employing the dynamic simulation software ADAMS, the virtual prototype model of the separation device is established, and the whole process of on-orbit...

In this paper, we aim to provide a better assembly method for a snap joints assembly task. We create a 3D cellphone model and use ADAMS simulation environment to analyze the relative motion between screen and backer part. We focus on two points in this research. 1) Two kinds of relative motion between...

This paper presents a new design method for a self-repairing adaptive PID control system. The control system has the adaptive adjusting mechanisms for the PID gains, and also can detect the sensor failure by self-test using the integrator in the PID controller. Hence, for plants with unknown parameters,...

Ensuring of the traceability of deliverables is one of effective methods to secure the quality of software. It can verify that the requirements are reflected in the programs. But it has two problems: taking much labor and time, and causing mistakes by human handling. This paper has implemented RETUSS...

In this paper, we propose a new design method of a second-order plus dead-time (SOPDT) sampled-data Proportional-Integral-Derivative (PID) control system, where the continuous-time plant is controlled using the discrete-time controller. The proposed control system is designed so that the tracking performance...

An EPN (Extended Place/transition Net) is used as a formal model that represents the behavior of software. When mutation testing is performed based on the EPN, failures are intentionally inserted into an original EPN (EPN that represents the expected behavior of software) in order to create mutant EPNs....

Molecule Robotics have been realized by using bio molecules such as DNA, proteins, for example in Molecular Robotics Research Project [2012-17, JSPS]; bio molecules, such as DNA or proteins are highly structured and they already have a kind of “intelligence” and adapt to environment change. Hence, we...

Recently, improvement of production efficiency on cars manufacturers is required. However, that improvements under existing circumstances are depending on experience and intuition by workers. We propose to objectively and efficiently improve a production line based on a GA. The difficulty of applying...

This paper proposes a concept of a training system for the speech controlled environmental control system: Bio-Remote based on candidate word discriminations. The proposed system can provide three-types of voice signal training: (1) volume, (2) tempo/timing and (3) candidate word which are important...

This paper combines the niche particle concept and quantum-behaved particle swarm optimization (QPSO) method with chaotic mutation to train neural networks for image inspection. When exploring the methodology of reinforced quantum-behaved particle swarm (RQPSO) to train neural networks (RQPSONNs) for...

Today one of the key disadvantages of robotic surgery is a lack of a haptic feedback, while in traditional surgery a surgeon uses human haptic senses in all tasks. Providing robots with a haptic feedback have a high potential of reducing time that is spent by a surgeon on suturing subtasks and helping...
