Nowadays engineer students, typically of automation, need to prove their PLC logic programs against diverse automatic systems, this gives the student a competitive approach to the working world. For a student to prove their knowledge, a fully equipped laboratory oriented for this course is needed. For the purpose of automation only, it is required at least a PLC for control, a PC for communication and of course that something to control. Evidently not all the universities can afford this fully equipped laboratory. For this problematic situation we propose an innovative solution: Virtual Machine Models, which substitute completely the entire components of the previously mentioned laboratory, for one or many virtual not expensive cells or stations. these Virtual Models behave identically to a real mechanical model, but with several advantages. these machines are in 3D, so the user can explore them entirely, they are inexpensive, easy to reproduce, unbreakable, light weighted and can run in any computer. they also are adaptable to be used not only in automation but in other engineering areas.

Starting from their freshman year, automotive engineering students at FH Joanneum are involved in project work within the framework of project-based learning. Software projects complementary to the regular courses in the second and third semester increase the efficiency of knowledge transfer and fortify the students' motivation to learn and to co-operate actively. the second, requirement-intensified phase within this problem oriented curricular framework takes place in the junior year and involves student selected research and development projects. A popular and therefore most frequently chosen project is the development of a formula-style race car within the rules and standards of the Society of Automotive Engineers' international Formula Student competition. In this paper the impact of the Formula Student project on the Freshmen's and Sophomore's choice of student projects is described and discussed by specific examples. the fact that the young students take the initiative and define their own research topics poses new challenges to the project supervisors. the students' motivation, creativity and problem-solving skills ought to be supported while at the same time the projects' feasibility must be assured. Students and advisors need to agree on applicable solution strategies in the different phases of the projects.

In recent years, the declarative programming philosophy has had a visible impact oil new emerging disciplines, such as heterogeneous multi-agent systems and flexible business processes. We address the problem of forma;verification for systems specified using declarative languages, focusing in particular on the Business Process Management field. We propose a verification method based on the g-SCIFF abductive logicprogramming proof procedure and evaluate our method empirically, by comparing its performance withthat of other verification frameworks.

We present a logic interpreted over integer arrays, which allows difference bound comparisons between array elements situated within constant sized window. We show that the satisfiability problem for the logic is Undecidable for formulae with a quantifier prefix {there exists, for all} *for all*there exists*for all*. For formulae With quantifier prefixes in the there exists*for all* fragment, decidability is established by an automata-theoretic argument. For each formula in the there exists*for all* fragment, we can build a flat counter automaton with difference bound transition rules (FCADBM) whose traces correspond to the models of the formula. the construction is modular, following the syntax of the formula. Decidability of the there exists*for all* fragment of the logic is a consequence of the fact that reachability of a control state is decidable for FCADBM.

this paper presents a novel methodology for topic ontology learning from text documents. the proposed methodology, named Onto Term Extraction (Term Extraction for Ontology learning), is based on OntoGen, a semi-automated tool for topic ontology construction, upgraded by using an advanced terminology extraction tool in an iterative, semi-automated ontology construction process. this process consists of (a) document clustering to find the nodes in the topic ontology,(b) term extraction from document clusters, (c) populating the term vocabulary and keyword extraction, and (d) choosing the concept names by comparing the best-ranked terms withthe extracted keywords. the approach was successfully used for generating the ontology of topics in Inductive logicprogramming, learned semi-automatically from papers indexed in the ILPnet2 publications database.
