Using 3.3 pb of data collected with the CMD-2 detector in the 720 – 840 MeV c.m. energy range, the branching fraction of the conversion decay ω → πee has been measured: B(ω → πee) = (8.19 ± 0.71± 0.62) · 10. The upper limits for the branching fractions of the following conversion decays have been obtained at the 90% confidence level: B(ρ → πee) < 1.6 · 10, B(ρ → ηee) < 0.7 · 10 and B(ω → ηee) <...
Two integrator backstepping designs are presented for digitally controlled continuous-time plants in special form. The controller designs are based on the Euler approximate discrete-time model of the plant and the obtained control algorithms are novel. The two control laws yield, respectively, semiglobal-practical stabilization and global asymptotic stabilization of the Euler model. Both design...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

karim khan can be considered as the only authoritative king in the whole zand era, thus the cultural and artistic foundations of this vary era is related to his government and him. seemingly, he was uneducated; however, he was interested in art, literature, and science. therefore, his court was the concourse of scientists, scholars, and artists. moreover, he has supported so many architectural ...
Using a discourse analytic qualitative approach, we investigated the naturally-occurring discourse that arose as part of two kinds of regular course activities, synchronous and asynchronous computer-mediated discussions. The messages contributed by members of a graduate course were analyzed for the kind of discourse functions and the kind of politeness strategies they displayed. Results indicat...
Theoretical studies of process flexibility designs had mostly focused on average-case analysis. In this paper, we take a different approach by studying process flexibility designs from a worst-case point of view. To study the worst-case performances, we introduce the so-called plant cover index, an index defined by a constrained bipartite vertex cover problem associated with a given flexibility...
