    This paper develops a commute travel mode choice logit model with imprecision explanatory variables to forecast commute travel demand. In traditional travel mode choice logit models, all variables are used in utility function as precision variables. Others, in many fuzzy travel mode choice models, only imprecision variables are used. They will decrease the accuracy of models estimated. In this paper, we deal with imprecision variables using fuzzy reasoning method, then use them and precision variables in utility function of logit model. Excellent correspondence was achieved between the results obtained from using the model and the real data. We also predict the impact of the policy change.

    In pervious psychological studies, human visual distance perception has been investigated minutely. However, the problem of human visual and tactual distance perception is still in controversy. In this study, human visual and tactual characteristics of spatial distance perception are measured. The results of experiment suggest that the human perceptive distance is larger than the actual distance if with tactile information, while the human perceptive distance is smaller than the actual distance if without tactile information. In order to analyze the results of experiment quantitatively, we propose a model of visual and tactual distance perception, while can explain the experimental results in a satisfactory manner.

    The dynamics of a manipulator with free joints is described by nonlinear ordinary differential equations with nonintegrable differential constraints. Such a dynamical system cannot be converted to a linear system using an exact linearization method such as the computed torque method. Control methods using nonlinear properties of such a system are studied in many fields of robotics. In this paper, we consider behavior of the free link on a two-link planer manipulator under commanding repetitive tasks to the actuated link. As previous reported, we numerically observed some periodic motions and chaotic states as a steady state on the manipulator. Computing bifurcation diagrams and basins of attraction for typical periodic motions, we investigate a relation between the viscous friction of the free joint and bifurcation phenomena on the manipulator. We also observe some periodic motions on an experimental manipulator system.

    In this paper we discuss a fuzzy classifier with hyperbox regions which has quadratic membership functions. First we define the classifier with quadratic membership functions and then discuss the training method that maximizes the recognition rate by counting the net increase in the recognition rate when the slope and the center of a membership function are separately changed. Finally, we demonstrate the recognition improvement by quadratic membership functions for four data sets.

    This paper considers measurement feedback switching control of systems with pointwise-in-time state and control constraints. Prior works have proved that switching control strategies have ability to resolve a common conflict in the design of state regulators : meeting performance requirements such as fast response and good disturbance rejection while simultaneously avoiding violation of specified state and control constraints. However, all of such switching control strategies are derived under consideration of full state feedback. In this paper, measurement feedback switching control law is proposed. The main idea is to utilize a set-valued estimation technique which produces a set of possible state vectors consistent with measured output data. Admissibility conditions on the initial state are satisfied, proposed output feedback switching control law is proved to fulfill the constraints and stability requirements. The disadvantage of this approach is that the online computational burden may severely limit its applicability, especially for systems with fast dynamics.
