The double-axial pump-controlled folding machine is a coupled system and has significant structural interaction. This paper proposes a coupled adaptive self-organizing sliding-mode fuzzy controller (CASOSMFC) to improve its level control performance. CASOSMFC is associated with two basic single-axial sliding-mode fuzzy controllers, self-learning fuzzy rule mechanisms, adaptive laws, coupled controllers and regulators. Different loadings are used to simulate different working pieces and variety coupled intensity folding processes. Experimental results indicate that CASOSMFC applied in the folding machine has excellent level control performance and has strong robustness to different coupled intensity.

This paper presents a novel sliding mode control (SMC) algorithm to handle mismatched uncertainties in systems via a novel self-learning disturbance observer (SLDO). A computationally efficient SLDO is developed within a framework of feedback-error learning scheme in which a conventional estimation law and a neuro-fuzzy structure (NFS) work in parallel. In this framework, the NFS estimates the mismatched disturbances and becomes the leading disturbance estimator while the former feeds the learning error to the NFS to learn system behaviour. The simulation results demonstrate that the proposed SMC based on SLDO (SMC-SLDO) ensures robust control performance in the presence of mismatched time-varying uncertainties when compared to SMC, integral SMC (ISMC) and SMC based on a basic nonlinear disturbance observer (SMC-BNDO), and also remains the nominal control performance in the absence of mismatched uncertainties. Additionally, the SMC-SLDO not only counteracts mismatched time-varying uncertainties, but also improve the transient response performance in the presence of mismatched time-invariant uncertainties. Moreover, the controller gain of the SMC-SLDO is required to be selected larger than the upper bound of the disturbance estimation error rather than the upper bound of the actual disturbance to guarantee system stability, which results in eliminating the chattering effects on the control signal.

The purpose of this research is to investigate and understand how students are using computer. The activities that a student undertakes with the help of computers which might be fulfilling some academic or non academic purpose, is of great interest. It will help in understanding the limitations and potentials offered by the technology for use of computer in classroom. This paper brings out the three major kinds of activities that students undertake with computer; self learning activities, Information collection tasks and communication and group activities. The study further analyses the effect of demographics i.e. gender, age and faculty (department) of students on the activities with computer. The results show that gender has no impact on the activities of students with computer. The age impacts only the activities related to Information collection by using computer where as the faculty of student significantly impacts all the activities viz. self learning activities, Information collection tasks and communication and group activities. The findings from this research can be used in designing future e-learning initiatives and development e-learning tools

Abstract The idea of the conceptualization of adult education has been postulated in the article including its significant differences. The leading distinguishing feature is the personality of pedagogical staff that works with adults. It has been substantiated the dependence of the functions which are performed by pedagogical staff in the adult education system, on the main characteristics of the society. It has been shown the content of the integral-role position of a pedagogue-andragogue which has 3 elements: subject and content, project and technological, organization and diagnostic. The professional activity of a pedagogue-andragogue has been analyzed as the specialist who professionally organizes and conducts adult training and learning, helps create individual programs of training. At the same time, in his/her activity he/she combines different social functions as well. The most typical are to provide the help in renovating the motivation towards learning and professional activity, to combine the content both andragogical and professional activity of his/her learners, to share the methods of supervising adult self-learning.

<p>The purpose of this study were to determine: 1) the influence of the learning <br />model of creative thinking; 2) the influence of self-concept to think creatively, and 3) the influence of the interaction and the concept of self-learning model for creative thinking. The research method used was experimental method. A sample of 80 people selected at random from the 13 study groups. The data was collected by administering a written test questions to measure variables studied. Data analysis using descriptive statistics and 2-way ANOVA. The results showed: 1) a significant difference to the learning model with the ability to think creatively sig = 0.000; 2) there is a significant effect of self-concept of <br />the ability to think creatively with sig = 0.000, and 3) there is a significant interaction effect of learning model and self-concept of the ability to think creatively with sig = 0.018. </p>
