We describe an implementation of a Java program to perform automated deduction in propositional multi-modal logics on a Java smart card. The tight space limits of Java smart cards make the implementation non-trivial. ...

We describe the implementation and management of a flexible model for multilevel distance learning-based teacher training. The model was implemented to introduce curricular and pedagogical aspects of teaching logic programming, to high school computerscience leading teachers, in the framework of an in service course. Although the advantages of preparing a unique training program for each teacher and initiating peer collaboration were clearly demonstrated during the course, we also noticed several difficulties that may be associated with the decentralization of the course and the exposure and accessibility of the Web-based communication.

The paper develops novel bounded model checking (BMC) techniques for labeled transition systems. The aim is to increase the efficiency of BMC by exploiting the inherent concurrency in the product of LTSs in order to cover more executions of the product within a given bound. This is done by considering a non-standard execution model, step executions, where multiple actions can take place simultaneously and where component LTSs are determinized on-the-fly, i.e., a component may be in a set of states in a step instead of in just one as in standard interleaving executions. Step executions can be further restricted to a subclass called process executions without losing reachable states. For bounded model checking of reachability properties of the product of LTSs the paper presents translation schemes from LTSs to a constrained Boolean circuit such that satisfying valuations of the circuit correspond to step (process) executions of the product. The translation schemes have been implemented and some experimental comparisons performed. The results show that the bound needed for step and process executions is in most cases lower than in interleaving executions and that the running time of the model checker using process executions is smaller than using steps. Moreover, the performance compares favorably to a state-of-the-art interleaving BMC implementation in the NuSMV system.

Effectiveness of testing criteria is the ability to detect failure in a software program. We consider not only effectiveness of some testing criterion in itself but a variance of effectiveness of different test sets satisfied the same testing criterion. We name this property "tolerance" of a testing criterion and show that, for practical using a criterion, a high tolerance is as well important as high effectiveness. The results of empirical evaluation of tolerance for different criteria, types of faults and decisions are presented. As well as quite simple and well-known control-flow criteria, we study more complicated criteria: full predicate coverage, modified condition/decision coverage and reinforced condition/decision coverage criteria.

We describe a program in multidisciplinary education of microelectronics systems design at the University of Notre Dame. In the "Bits-to-Chips" course sequence, faculty from the Electrical Engineering and computerscience and Engineering Departments, and the Kaneb Center for teaching and Learning have coordinated their related courses and teachingmethods, and team-teach a course on advanced technologies and systems-on-a-chip (SOC). Projects in the capstone course have involved the design and fabrication, completely by the students, of CMOS circuits with 10,000 transistors, and are now developing projects with roughly 50,000 devices. A recent project is an accelerometer control chip for insertion into a model rocket launch. Projects are also submitted to MOSIS for comparison with the students' efforts.
