Extracts of Aloe vera whole plant, Eucalyptus globulus leaves, Ficus infectoria bark, Ficus religiosa bark and Piper betel leaves were studied for antibacterial activity on resistant and sensitive strains, isolated from skin and soft tissue infections. A combination of hot alcoholic extracts of Ficus infectoria, Ficus religiosa and Piper betel were found to be more effective against all the iso...

We consider in this report systems modeled by timed automata. The timing bounds involved in the action guards and location invariants of our timed automata are not constants, but parameters. Those parametric timed automata allow to model various kinds of timed systems, e.g. communication protocols or asynchronous circuits. We will also assume that we are given an initial tuple π0 of values for ...

In recent decade security systems based on biometric technologies have played an important role in our community. Fingerprint identification is one of the most important biometric approaches. The uniqueness of a fingerprint is exclusively determined by the local ridge characteristics called minutiae. The automatic fingerprint matching depends on the comparison of these minutiae and their relati...

Environmental pollution and its eco-toxicological impacts have become a large interesting concern worldwide as result of fast urbanization, population expansion, sewage discharge, heavy industrial development. Nine metals (Pb, Cd, Fe, Mn, Zn, Ni, Cu, Cr, Co) were evaluated in 20 sediment samples from the estuaries four major drains along Mediterranean shoreline (Nile Delta coast) to determine p...

This chapter introduces the first basic concepts of co-modelling and co-simulation, including notions of system, model and co-model, simulation and co-simulation, etc. It also describes the ways in which co-modelling and co-simulation can be integrated with established development processes such as IEEE 15288 (Systems and Software Engineering—System Life Cycle Processes, [45]) and IEEE 12207 (S...

Results from phylogenetic analysis of nuclear rDNA internal transcribed spacer (ITS) sequences from a worldwide sample of Sanicula indicate that Hawaiian sanicles (Sanicula sect. Sandwicenses) constitute a monophyletic group that descended from a western North American ancestor in Sanicula sect. Sanicoria, a paraphyletic assemblage of mostly Californian species. A monophyletic group comprising ...

Preface Designing Screening Experiments (DSE) is a class of information-theoretical models for multiple-access channels (MAC). In Sect. 2-4, we discuss the combinatorial model of DSE called a disjunct channel model. This model is the most important for applications and closely connected with the superimposed code concept. In Sect. 2, we give a detailed survey of lower and upper bounds on the ra...

Pad6 approximants are a frequently used tool for the solution of mathematical problems. One of the main drawbacks of their use for multivariate functions is the calculation of the derivatives of f ( x 1 .... ,xp). Therefore multivariate Newton-Pad6 approximants are introduced; their computation will only use the value of f at some points. In Sect. 1 we shall repeat the univariate Newton-Pad6 ap...
