Commercial dental lithium disilicate based glass-ceramics containing various amounts of P2O5 were synthesized. Regarding the crystallization behavior and physico-chemical properties of the glasses, the optimum percent of P2O5 was determined.as 8 %wt. Crystallization behavior of the glasses was investigated by X-ray diffraction (XRD) and differential thermal analysis (DTA). The micro-hardness a...

Although the Biot-Gassmann equations are known to predict acoustic data for water-saturated glass bead packings very well, these equations often seem to give anomalous results for naturally occurring rocks. The theory shows that, as the compressibility of the pore uid increases, the inverse of the coeecients C and M in Biot's equations should increase linearly, and the theory also gives deenite...

Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at T f535 K and frequency-dependent susceptibility below T f . The field-cooled and zero-field-cooled magnetization diverge below T f , with hysteresis characteristic of a spin glass. A resistivity minimum just above T f is explained in terms of c...

In this work, Er 3+ -doped phosphate glass with good flatness of the emission spectrum L+ band was prepared by optimizing content BaO. The absorption and spectra were measured. Increase BaO is conducive to broadening in band. dependence Raman intensity has been shown linear fitting. results show...

Achromatic doublets have been used for decades to minimize the effects of chromatic aberrations inherent to single-glass optical lenses. Here, we propose a fundamentally different solution to correct the chromatic aberrations based on a nanowire metamaterial with low loss anomalous dispersion. We show that by coating a standard glass lens with the metamaterial it may be possible to design a com...

We study a model in which particles interact through a hard-core repulsion complemented by a short-ranged attractive potential of the kind found in colloidal suspensions. Combining theoretical and numerical work we locate the line of higher-order glass-transition singularities and its end point-named A4-on the fluid-glass line. Close to the A4 point, we detect logarithmic decay of density corre...

An important application in network analysis is the detection of anomalous events in a network time series. These events could merely be times of interest in the network timeline or they could be examples of malicious activity or network malfunction. Once a set of events are identified by the anomaly detection algorithm, a more detailed examination of the graph at these times can reveal importa...

The aim of this paper is to provide an active inference algorithm for anomalous behavior. As a main concept we introduce fuzzy temporal consistency covering set, and put forward a fuzzy temporal selection model based on temporal inference and covering technology. Fuzzy set is used to describe network anomaly behavior omen and character, as well as the relations between behavior omen and charact...
