Protection of privacy in databases has become of increasing importance. While a number of techniques have been proposed to query databases while preserving privacy of individual records in the database, very little is done to define a measure on how much privacy is lost after statistical releases. We suggest a definition based on information theory. Intuitively, the privacy loss is proportional...

Vascular changes undoubtedly play a significant role in the pathogenesis of psoriasis. The present study concerns the local hemodynamics of psoriatic plaques measured by skin clearance of radioactive substances. This method gives a rough measure of local vascular dynamics (1—7), and, despite any shortcomings, probably supplies a more realistic picture than does use of colorimetry or plethysmogr...

Abstract Purpose: In the current research, the relationship between financing and the three factors of the quality of educational services, the quality of the educational environment and social interactions was examined. On the other hand, the relationship between the three mentioned factors and achievement of educational goals was also investigated. Methodology: the method was descriptive - c...

The authors address the value of endoscopic retrograde cholangiopancreatography, ultrasonography, computed tomography, magnetic resonance imaging and endoscopic ultrasound for the diagnosis of cystic and solid neoplasms of the pancreas, demonstrating that each of them is of great importance to undoubtedly increase the diagnostic accuracy of the biliopancreatic system diseases. The best method f...

Weakly recognizing morphisms from free semigroups onto finite semigroups are a classical way for defining the class of ω-regular languages, i.e., a set of infinite words is weakly recognizable by such a morphism if and only if it is accepted by some Büchi automaton. We consider the descriptional complexity of various constructions for weakly recognizing morphisms. This includes the conversion f...

The communication structure of parallel communicating grammar systems (PCGS) considered as the descriptional complexity of PCGS is investigated here. The aim of the paper is to compare computational power of PCGS’s with respect to their communication structure. Investigating the generation of the languages over one-letter alphabet the communication structures dags(directed acyclic graphs) and c...
