Let g be a complex simple Lie algebra, with fixed Borel subalgebra b⊂g and Weyl group W. Expanding on previous work of Fan Stembridge in the simply laced case, this note aims to study fully commutative elements W, their connections spherical nilpotent orbits g. If is not type G2, it shown that an element w∈W if only b determined by inversions w lies closure orbit. A similar characterization als...

One of the aims of ELENA project (www.elena-project.org) is to support personalized access to distributed learning repositories. In this talk we will present an approach to personalization we employed in ELENA. We take advantage of semantic web technologies and metadata description standards. Explicit descriptions of learning objects described in RDF bindings of LOM and DC, and learners in inte...

The paper presents the concept of a component an aircraft’s automatic flight control system, controlling airplane when in longitudinal motion (i.e., pitch angle, sink rate, airspeed channels) during landing, from final approach until touchdown. It is composed two key parts: vision system and landing system. first part exploits dedicated image-processing algorithms to identify number red white P...

The purpose of the PAPI project is to specify a standard application programming interface (API) for accessing hardware performance counters available on most modern microprocessors. These counters exist as a small set of registers that count events, which are occurrences of specific signals and states related to the processor’s function. Monitoring these events facilitates correlation between ...
