In this paper, we introduce our e-learning project that aims to make of creation, integration and interfacing of multiple ontologies on different layers, i.e. Curriculum ontology, Syllabus ontology, and Subject ontology. The primary objective of our project is to develop ontology-based e-learning support system which allows learners to build adaptive learning paths through understanding curricu...

The application of quality processes to tertiary teaching can result in a more team-based approach to course curriculum planning, the instructional design of individual subjects or units, the learning support associated with subject implementation and subsequent evaluation. The "art" of teaching requires more explicit communication within and across different teams that may be involved in each ...

With the rapid growth of the Internet users and its applications there has been considerable interest in Web-based education systems that facilitates distance education. In this paper, we propose a Subject Model for Web-based Education system. The designed model uses a tree with multiple links. Each link weight has been derived from the conceptual relations, among the concepts of the subject. T...

Consider that a linear time-invariant (LTI) plant is given and that we wish to design a stabilizing controller for it. Admissible controllers are LTI and must comply with a pre-selected sparsity pattern. The sparsity pattern is assumed to be quadratically invariant (QI) with respect to the plant, which, from prior results, guarantees that there is a convex parametrization of all admissible stab...

In this work connected cruise control with digital controllers is investigated for a vehicular string on a single lane. The longitudinal control of each vehicle is based on the information broadcast by other vehicles via wireless communication. We demonstrate that intermittencies and packet loss introduce time-dependent time delays in the control loop that may destabilize the system. We analyze...

Although many attempts have been made in presenting systematic models for design processes, most projects have been implemented by non-systematic methods, which seems that too much emphasis on the description of the final project (product) and the lack of attention to the design process are to be blamed for this. In this paper, a specific pattern of design scenario formation in the framework of...

A new meta-heuristic algorithm is proposed for optimal design of reinforced concrete (RC) frame structures subject to combinations of gravity and lateral static loads based on ACI 318-08 design code. In the present work, artificial bee colony algorithm (ABCA) is focused and an improved ABCA (IABCA) is proposed to achieve the optimization task. The total cost of the RC frames is minimized during...
