    Notes: This paper describes the integration of a feedforward neural network with a real-time adaptive control technique to model an assembly cell for computer keyboards. The simulation model is able to undertake real-time forecasting of the expected behaviour of the cell, and also able to display in real time the current status of the assembly cell. The potential of integrating artificial neural networks into simulation together with an on-line real-time interface between the simulation model and the real-world system is investigated in this study. A simulation model was built in SIMAN with a neural network written in NeuralWork Professional II Plus embedded in the model to allow training and testing of the network. The control of the cell was achieved through a third-party program written in C that interfaces directly to the cell.

    Notes: Abstract The electrochemical behaviour of a hydrogen/oxygen gas mixture at platinum electrodes in contact with a solid polymer electrolyte (Nafion 115) was studied in two modes: hydrogen enrichment and fuel cell. In the hydrogen enrichment (purification) mode, i/V(V being the applied voltage) characteristics were identified for the electrochemical cell arranged so that the gas mixture with varying ratios which contacts the anode was purified to pure hydrogen gas that was released at the cathode. In the fuel cell mode, V/i (V being the terminal voltage) characteristics were determined for the cell which utilized the gas mixture with varying ratio at the anode and pure oxygen at the cathode. The effect of the decrease in the mole fraction of hydrogen (χH2) on the current density or the terminal voltage was particularly severe for χH2〈0.6. The drop was analysed employing terms such as oxygen reduction current, oxygen adsorption and the change of e.m.f. (electromotive force) due to the decrease in the partial pressure of the hydrogen gas.

    Notes: Abstract The aim of this experimental study is to investigate the heat (mass) transfer of a rotating disk with an impinging circular jet. To facilitate the experiments, the naphthalene sublimation technique was employed. In order to analyze the results, measurements of the heat (mass) transfer of a stationary disk with an impinging jet and a rotating disk without jet impingement were also made. From the experimental results, it is found that the heat (mass) transfer are precisely divided into three regimes, namely the impingement dominated regime; the mixed regime and the rotation dominated regime. Correlation of Sherwood number of a rotating disk with jet impingement is also proposed in the present work.

    Notes: Abstract  Using Genetic Programming (GP)-based approaches to evolve robot controllers has the advantage of operating variable-size genotype. This is an important feature for evolving robot control systems as it allows complete freedom for the control architecture in respect to the task complexity which is difficult to predict. However, GP-based work in evolving controllers has been questioned in the verification of the performance on real robots, the generalisation of defining primitives, and the computational cost needed. In this paper, we present our GP framework in which a special representation of the robot controller is designed; this representation can capture well the characteristic of a behaviour controller so that our system can efficiently evolve desired robot behaviours by a relatively low computational cost. This system has been successfully used to evolve reliable and robust controllers working on a real robot, for a variety of tasks.

    Notes: Abstract  The precision of transferred patterns are highly dependent on the quality of the mask in deep x-ray lithography. Many parameters, such as the critical energy of the synchrotron light, beamline optics and even the microstructure to be exposed should be considered in mask design. In this paper, the design rules and the boundary conditions for deep x-ray mask are discussed in general. The method of making a precision, multilayer mask using UV lithography technique is also described.
