The process of tension control for material testing using the Flexible Circuit Board testing machine (FCBTM) is featured with multi-variable, nonlinearity, time delays and time variation. In order to ensure the tension precision, the stability of servo motor’ speed and the reliability of test results, this paper establishes an accurate system model for the FCBTM, in which a novel three-dimensio...

In this article, the author focuses on issues concerning musical composition practices in which emergent behavior is used to generate musical material, musical form or both. The author gives special attention to the potential of cellular automata and adaptive imitation games for music-making. The article begins by presenting two case-study systems, followed by an assessment of their role in the...

The huge and exponentially growing diversity of digital material confuses the users who are confronted to the difficulty of choosing the right and appropriate document or information. On the same way the federation of Learning Object Repositories could conduct to the same difficulty while wanting to obtain a critical mass of learning object in order to facilitate their reusability. In this pape...

This paper argues that a way to the new generation of powerful E-learning systems starts on the crossroads of two emerging fields: courseware re-use and adaptive educational systems. This paper presents the KnowledgeTree, a framework for adaptive Elearning based on distributed re-usable learning activities that we are currently developing. The goal of KnowledgeTree is to bridge the gap between ...

nonlinear static procedure (nsp) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure. therefore, the pushover analysis is an important part of each nsp. accordingly, the current paper aims at investigating the efficiencyof various algorithms of lateral load patterns applied to the...

We have developed an ultrabroad-band regenerative amplifier with a mirrorless cavity to eliminate the limitation of bandwidth of dielectric coats on cavity mirrors. A large amount of material dispersion in Pellin-Broca prisms which are used instead of the cavity mirrors is compensated using a hybrid technique of Brewster prism pairs in the regenerative amplifier and an adaptive phase controller...

This paper describes a competence–based approach to adaptive e–learning based on knowledge space theory and its competence–performance extension. Assigning to each learning object sets of required and taught competencies, one can easily build a course adapting in each step to the learner’s current knowledge state. The competence assignments implicitly define a prerequisite structure on the set ...

We present an adaptive P1 finite element method for two-dimensional transverse magnetic time harmonic Maxwell’s equations with general material properties and general boundary conditions. It is based on reducing the boundary value problems for Maxwell’s equations to standard second order scalar elliptic problems through the Hodge decomposition. We allow inhomogeneous and anisotropic electric pe...

E-learning may provide a lot of useful features in a wide range of learning and teaching situations. However, the provision of static learning material will not meet the requirements of the users. We believe that well-tailored, highly personalized learning sessions are needed. Regarding to this background, the research project AdeLE (Adaptive e-Learning with Eye-Tracking) aims to develop and im...
