We demonstrate a method, permitting the observation of dielectric loading of hydrocarbons into a porous coordination polymer nanocrystal (PCP), by spatially resolving the phase difference between the near-field responses of two terahertz resonators.
For example, there exist some wheelchair users, who cannot operate a powered wheelchair well by using a joystick, which is usual manipulation equipment of powered wheelchairs. A prototype of our group has simple manipulation equipment, constructed by buttons or levers. This operation equipment restricts the running performance of wheelchair. On the other hand, due to the restricted running performance,...
On a PET scanner consisting of block detectors, coincidence responses to scattered radiation may differ from those to trues depending on the crystal pair position within a coincidence block pair. Furthermore, these differences are considered to vary according to the radial position of the coincidence block pair. In component-based normalization, a scatter-compensated geometrical component is therefore...
In this paper, a novel method to synthesize a desired trajectory and sensory feedback control laws for robots based on the statistical characteristics of direct teaching data by a human is proposed. This work was motivated by a poor performance of an origami-folding robot developed by the authors. Since the robot simply replayed a given trajectory without sensory feedback control, it often failed...
This paper presents a comparison result of micro helicopter control via a typical linear matrix inequality (LMI) approach and a sum of squares (SOS) approach. First we construct a dynamical model of a micro helicopter and convert it to a Takagi-Sugeno fuzzy model. Next, this paper summarizes a recent developed SOS design approach for polynomial fuzzy control systems based on polynomial Lyapunov functions...
We are studying an intelligent perceptual information processing system in which plural processing can run in parallel. Our proposed mathematical activation-input-modulation (AIM) model controls each execution frequency of plural processing independently based on degrees of stimuli detected by external sensors. When external stimuli are detected by some of external sensors, information processing...
We have developed a wide area intruder detection surveillance system which was delivered to the Japanese market last summer. This technology is known as MELWATCH which stands for MELco WATCH(to keep lookout). It has been installed at several sites in Japan. MELWATCH is composed of a pair of sensor cables, a sensor unit and an intrusion detection terminal. The sensor cables are composed of a transmission...
Highly reliable safety monitoring systems are indispensable for operating large-scale systems, such as nuclear power plants. This paper proposes anew type of reliable safety monitoring system employing a small number of autonomous decentralized mobile sensors. The new system is called ant-like sensor system (ALSS), and consists of autonomous sensors utilizing pheromone communication. Each sensor moves...
