Microsoft Word - QAS-TB3.DOC
Quality-Assuring Scheduling (QAS) has been invented to provide statistical guarantees to real-time applications with variable execution times scheduled in a reservation-based fixed-priority system. The admission control is based on a probabilistic model to ensure that a requested percentage of jobs of a periodic application is successfully executed over a longer time span even in permanent over...
متن کاملDetermination of heparin using ciprofloxacin-Tb3+ as a fluorescence probe.
A new spectrofluorometric method was developed for the determination of trace amounts of heparin (Hep). Using ciprofloxacin (CIP)-terbium (Tb3+) as a fluorescent probe, in a buffer solution of pH 7.20, Hep can remarkably enhance the fluorescence intensity of the CIP-Tb3+ complex at lambda = 545 nm; also, the enhanced fluorescence intensity the Tb3+ ion is proportional to the concentration of He...
متن کاملLabel-Free Ag+ Detection by Enhancing DNA Sensitized Tb3+ Luminescence
In this work, the effect of Ag⁺ on DNA sensitized Tb(3+) luminescence was studied initially using the Ag⁺-specific RNA-cleaving DNAzyme, Ag10c. While we expected to observe luminescence quenching by Ag⁺, a significant enhancement was produced. Based on this observation, simple DNA oligonucleotide homopolymers were used with systematically varied sequence and length. We discovered that both poly...
متن کاملGreen-Emitting Gd3Ga5O12: Tb3+ Nanoparticles Phosphor: Synthesis, Structure, and Luminescence
Nano- and microceramics of Gd3Ga5O12 garnet doped with 1 mol % Tb3+ ions were synthesized via co-precipitation and high-temperature solid-state reaction methods. X-ray diffraction measurements confirmed the formation of the garnet structure with Ia3d space group in all investigated samples. Atomic force microscopy surface images and grain-size distribution diagrams of Gd3Ga5O12: 1 mol % Tb3+ na...
متن کاملSynthesis and luminescence properties of YF3:Ce3+/Tb3+ nanocrystals.
YF3:Ce3+, YF3:Tb3+, and YF3:Ce3+/Tb3+ nanocrystals were synthesized by an ethylenediaminetetraacetic acid (EDTA)-assisted hydrothermal method and characterized by X-ray diffraction and scanning electron microscope. In the excitation spectra, there is one broad excitation band at 285 nm for YF3:Ce3+ and 255 nm for YF3:Tb3+, which are related to the f-d excitations of the Ce3+ and Tb3+ in the hos...
