ABSTRACT The latest researches adopted software technology to improve pointing performance; however, Drag-and-Drop (DnD) operation is also commonly used in modern GUI programming. This study evaluated whether two children with developmental disabilities would be able to improve their DnD performance, through an Automatic DnD Assistive Program (ADnDAP). At first, both participants had their baseline sessions. Then the first participant entered into intervention. New intervention began with the second participant when his performance was consolidated. Finally, maintenance phase occurred with both participants, in which their DnD performance improved significantly. Data showed that both participants improved their DnD efficiency with the assistance of ADnDAP, and remained highly successful through maintenance phase. Implications of the findings are discussed.

    ABSTRACT: The latest research proposed a novel computer input device to improve people with disabilities pointing efficiency. The proposed device adopted Screen-Partitioning method that users could use a commercial numerical keyboard as the input device of the device instead of special-design device to provide users with an inexpensive, flexible, and easily maintained computer pointing device, and adopted an Auxiliary-Window-Screen design that provided users with a visual operating environment. However, the effect of the latest research in moving mouse cursor is likely weak when a target is extremely small or the resolution of computer screen is too high. Thus, this study proposed an extended design according to previous device to help people with disabilities improve the pointing efficiency.

    ABSTRACT: In this paper, the upper bounds for a multivariable fuzzy logic controller under Godel's implication have been investigated and a generalized multivariable structure of a fuzzy controller has been proposed. Contribution operators, such as the max (v) operation, ensure the greatest upper bound as well as the least upper bound. Conditions which determine an appropriate upper bound are also determined. This theory has applications in the design of fuzzy logic controllers.

    ABSTRACT: Measurement errors often lead to large uncertainties in parameter estimation for dynamical systems. However, a considerable improvement of the preciseness may be obtained by a suitable choice of the experimental conditions. An approach is given to calculate optimal input functions by solving a minimization problem, based on a calculation of the Fisher information matrix. This approach is applied to a model describing the growth of plant cells in suspension culture in a stirred tank reactor. The simple model is based on the metabolic structure, limiting rates, mass and energy balances of the cells as well as the reactor equations. A significant increase in the accuracy of the parameter estimations is shown to be possible by fed batch experiment design using the method indicated above, compared to the accuracy which could be obtained using batch experimental data.
