This paper describes a GNSS (Global Navigation Satellite System) precise point positioning (PPP) technique that can be applied to mobile robots in urban environments. The multipath signals, which from invisible satellites in urban area, cause serious effect on the GNSS positioning. Our proposed technique mitigates GNSS multipath signals by means of an omnidirectional infrared (IR) camera that can eliminate the need for invisible satellites by using IR images. With an IR camera, the sky appears distinctively dark. This facilitates the detection of the borderline between the sky and the surrounding buildings, which are captured in white, because of the difference in the atmospheric transmittance rates between visible light and IR rays. Positioning evaluation was carried out only with visible satellites that have less multipath errors. The evaluation results confirm the effectiveness of the proposed technique and the feasibility of its highly accurate positioning.

This paper presents a method for estimating player's belief related to Bayesian Nash equilibrium in a class of static Bayesian games. The method is to construct a feedback control system for a nonlinear plant that expresses evolution of a mixed strategy and a belief of the games. A numerical example confirms that their beliefs can be estimated by the proposed method.

Speech dialogue systems, such as Apple's “Siri,” have gradually become more widespread, and in the near future, a greater number of general users will have the opportunity to communicate with such systems. To facilitate this, it is necessary for the system to communicate more naturally with users, and to realize that both verbal and nonverbal information must be taken into consideration. In this research, using an available speech recognition platform, we have developed simple dialogue system that consider utterance timing and evaluated it. As a result, it is clarified that the mean error of generated pause duration is controlled within 20msec, and the proper fixed pause duration is turned to be 600msec in this system. Moreover, the evaluation of generative models of pause duration showed that the model that synchronized the utterance duration weakly or fixed pause duration (600msec) model tended to get best results.

A new method of Differential Non-linearity (DNL) error correction for the successive approximation A/D converter (SAADC) is proposed.The SAADC has very short conversion time and is very useful in various fields. But it has the largest DNL in comparison with any other type of ADC.The DNL is the channel width irregularity of ADC, and is the most difficult error to deal with since it cannot be eliminated by adjustment.The most famous research to equalize the channel width of SAADC is the Gatti's “Sliding Scale Method” proposed 28 years before approximately.This new method of DNL error correction is based upon the peculiar feature of the SAADC.First, the generation mechanism of DNL error is analyzed.Second, a new method of DNL error correction is proposed.Finally, the feasibility of this newly proposed method is confirmed through the computer simulations.

It is well known that the faster runs a train, the more dissipates its energy. In train schedule the running time is settled in advance, so the train needs to be operated in fixed time between stations. As the train could adopt various operation patterns in the fixed schedule, the requisite energy for the train operation varies according to its patterns even in the fixed time and distance. We can, therefore, consider a train operation method which minimizes the requisite energy.Our simple model of train operation enables to show that the train running energy is minimized when it runs in constant speed as long as possible in a specific time and distance supposing that the train moving energy were collected by the regenerating process in the brake operation.While in case of no regeneration of the energy we gained another operation pattern of the minimum energy. The minimum energy has followed from the train operation that after keeping the constant train speed and coasting, the brake should be applied at the instant of a calculated speed when the train stops. But a commuters' train can not take the sufficient coasting time in it's frequently stopped and comparatively high speed operation. We have made clear the energy minimum operation of such a commuters' train as a special case of the no energy regeneration.

Two types of photoelectric polarimeter, one of which is a direct reading polarimeter and the other an automatic polarimeter, have been developed to meet the requirement for rapid and continuous measurement of the optical rotation of optically active solution. In the direct reading polarimeter, each of two plane-polarized beams passes through either a standard liquid container or a sample container and a rotary analyzer, and finally impinges on a photomultiplier. Each of the two photomultipliers receives a flash of light modulated sinusoidally and generates a.c. signals, which are amplified and fed to the phasemeter. The output of the phasemeter indicates the optical rotational angle of the sample. The automatic polarimeter has two fixed analyzers and CdS cells. Each output of the cells is connected differentially and fed to a balancing motor which is connected mechanically to the polarizers. At first, the outputs of the two cells are balanced. When the samples are inserted into two optical paths, the motor rotates the polarizers until balance is restored. Each of the rotational angles of the polarizers indicates the optical rotational angle of the sample. The direct reading polarimeter and automatic polarimeter have an over-all accuracy within about±1% and are handy so that they are suitable for the use in the factory.

An entirely novel shape measurement method to obtain 3D shapes is proposed, based on a bilateral vibration touch probe that outputs feedback voltage in accordance with its position. A bilateral vibration touch probe, with high-stiffness, is developed. The proposed probe consists of a piezo-electric device and a thin needle, and generates feedback voltage according to the relative distance from the object. The structure of this probe is simple, so that it is able to withstand high rates of acceleration during the measurement process. The shape measurement is performed in an object of unknown shape and the shape of the object can be found by scanning the object surface. Moreover, a nonlinear synchronous multi-axis control algorithm is proposed in order to scan the surface of arbitrary objects and measure their 3D shape. The effectiveness of the proposed algorithm is demonstrated through experiments. When actual width of 1 mm was measured using the proposed nonlinear synchronous multi-axis control, a minimum error of 21.7 µm was obtained.

This paper proposes a method of controlling the tracking errors attributable to current based on a Heading Control System (HCS) which focuses on the aspects controlled by the heading of a Track Control System (TCS) and the aspects comprised in the straight and circular-leg segments of the planned route. The HCS is comprised of a reference heading and a 2-degree-of-freedom control (2DOFC) system to provide course keeping and course changing functions. The proposed method pertains to a tracking control loop for both the straight-leg and circular-leg segments of the route and involves separating the TCS into the HCS control loop and the tracking control loop and adopting a reference route derived from the reference heading and ship speed. In the straight-leg segments of the route, constant current components are estimated based on the tracking errors from the reference route and these current component estimates are used to correct side slip angle through feed back control. In the circular-leg segments of the route, the current component estimates are used to correct side slip angle and the turn rate through the reference heading and 2DOFC. As the ship's heading follows the reference heading by means of the feed forward control operation, the side slip angle cancels the current component of the route's normal direction. The rate of turn relates to changes in ground speed (sum of current and ship speed) to maintain a constant radius. Additionally, reach is estimated from the reference heading and the feed forward control. Reach refers to the distance from the start position of the circular-leg. The validity of this proposed method was verified by simulation results.

By using velocity estimation a new robust trajectory tracking control scheme is developed in this paper for wheeled mobile robots. The developed controller has the following features; i) The proposed controller has robustness not only for the weight and the moment of inertia but also for radius of wheels and distance from the reference point to both wheels. ii) It is easy by using design parameters to improve tracking performance.
