In this paper, using pre-semi-open L-sets and their inequality, a new notion of PS-compactness is introduced in L-topological spaces, where L is a complete De Morgan algebra. This notion does not depend on the structure of the basis lattice L and L does not need any distributivity.

According to the National Cancer Institute, more than 230,000 new cases of prostate cancer will occur in the United States in 2005. Prostate cancer is the second leading cause of cancer death in men, with an estimated 29,900 deaths in 2004 (American Cancer Institute, 2004).

Improving industrial product reliability, maintainability and, thus, availability is a challenging task for many industrial companies. In industry, there is a growing need to process data in real time, since the generated data volume exceeds the available storage capacity. This Paper consists of a review of data stream mining and data stream management systems aimed at improving product availab...

We present a preliminary but broad assessment of the ecloud build-up for the various proposed upgrades of the LHC and its injectors. The study pertains only to the ecloud in bending dipole magnets, and does not shed any light on the effects of the electrons on the beam. We focus on the ecloud heat load, although we have computed many other quantities of interest. The basic variable used to clas...
