In this work we demonstrate that high-energy electron beam irradiation (HEEBI) performed in air at room temperature affects remarkably the electrical, optical, and structural properties of undoped ZnO films prepared on SiO 2 substrates by magnetron sputtering techniques. Hall and photoluminescence measurements revealed that the p-type conductivity was realized in HEEBI treated films with low dose of 1014 electrons/ cm2 and converted to n -type conductivity with further increase in the amount of dose. X-ray photoelectron spectroscopy showed that indiffusion of Si from the substrate as well as N from the ambient into the films took place as a result of HEEBI treatment at high and low doses, respectively. X-ray diffraction analysis indicated that all as-grown films were found to have compressive stress, which was relieved to some extent by HEEBI treatment with high dose of 1016 electrons/ cm2. It was also found that better crystallinity with a bigger grain size was observed in HEEBI treated ZnO films with a higher dose. Field emission scanning electron microscope showed that HEEBI treated films with low dose had surface morphologies with big rodlike shapes. The major acceptorlike defects were determined to be oxygen interstitial and zinc vacancy. A model was proposed in terms of O, Zn, N, and Si diffusion to explain the observed results. © 2009 American institute of Physics.

In the situation in which a robot and a human work together by collaborating with each other, a robot and a human share one working environment, and each interferes in each other. In other ward, it is impossible to avoid the physical contact and the interaction of force between a robot and a human. The boundary of each complex dynamic occupation area changes in the connection movement which is the component of collaborative works at this time. The main restraint condition which relates to the robustness of that connection movement is each physical charactristics, that is, the embodiment. A robot body is variability though the embodiment of a human is almost fixed. Therefore, the safe and the robust connection movement is brought when a robot has the robot body which is well suitable for the embodiment of a human. A purpose for this research is that the colaboration works between the self-reconfiguration robot and a human is realized. To achieve this purpose, a self-reconfiguration algorithm based on some indexes to evaluate a robot body in the macroscopic point of view was examined on a modular robot system of the 2-D lattice structure. In this paper, it investigated effect specially that the object of learning of each individual was limited to the cooperative behavior between the adjoining modules toward the macroscopic evaluation index. © 2009 The institute of Electrical Engineers of Japan.

The paper presents a joint state and unmeasured input estimation technique for a special class of nonlinear second order macroscopic traffic model. The freeway traffic system is transformed into a quasi and affine approximate Lin- ear Parameter Varying (LPV) form. Observer design technique is formulated using off-line optimization problem subjected to Linear Matrix Inequality (LMI) conditions, considering uncertain scheduling parameters. Furthermore, locally designed state estimators are interconnected to cover multiple freeway sections. The elaborated method is validated using real traffic measurements. © 2009 EUCA.

This paper considers the optimal reference tracking control of an electropneumatic clutch actuator. To control both supply to and exhaust from the clutch actuator chamber, one pair of on/off valves is used. The on/off valves are controlled by pulse-width modulation. The fast dynamics of the clutch actuator and the presence of both state and input constraints makes it appropriate to design an explicit Model Predictive controller (MPC), where the only computation performed on-line would be a piecewise linear function evaluation. A multi-parametric Nonlinear Programming approach is applied to design the explicit MPC. In order to reduce the computational burden, the design of the explicit controller is based on a simplified 3-rd order model of the clutch actuator. The controller performance is verified by simulating with the full 5-th order model of the actuator dynamics. Also, the closed-loop response is compared to that of an explicit MPC controller without pulse-width modulation, where the valves are directly commanded fully open or fully closed. © 2009 EUCA.

Recently, several multi-parametric Nonlinear Programming approaches to explicit solution of constrained Nonlinear Model Predictive control (NMPC) problems have been suggested. The benefits of an explicit solution, in addition to the efficient on-line computations, include also verifiability of the implementation. However, the off-line computational complexity tends to increase rapidly with the number of states. In this paper, several approaches to reduce the off-line computational burden and the partition complexity of the explicit NMPC are proposed and illustrated with two examples. © 2009 EUCA.

Quantitative analysis and detection of abnormalities for electroencephalogram (EEG) recordings during evoked activities are essential for clinical diagnosis on neurological disorders. However, the process of interpreting EEG is time consuming and requires experienced electroencephalographers (EEGers). In this study, a method of automatic EEG interpretation during hyperventilation was proposed. The purpose is to provide a quantitative interpretation of EEG which is able to conform to EEGers' visual inspection. The final integrated results of automatic interpretation were compared with EEGers' evaluation, and showed high consistence. © 2009 SICE.

Active yaw stabilization for passenger vehicles, following driver yaw rate commands with steer-by-wire and rear break force distribution, is discussed. The problem is solved via a decomposition of the vehicle equations of motion into a static, scheduled tyre characteristics map, and an affine Linear Parameter Varying (LPV) plant. control is provided via a cascade connection of scheduled inverse tyre characteristics and an LPV controller, handling both the nonlinear dynamics an the non-affine tyre characteristics. Excellent tracking results are demonstrated with a high fidelity simulation even in the presence of noise and uncertainty.
