In order to fabrication of transparent glass-ceramics with Li-mica nano crystals, the glasses with chemical composition of 94.9 mass% Li(1+x)Mg3AlSi3(1+x)F2 (x=0.5) with 5.1 mass% MgF2 were crystallized. The glasses were fabricated via the conventional melt-quenching technique. Mica crystals were precipitated in the glass phase by later heat treatment. Glass samples had glass transition tempera...

The RobotMODIC project run by the Universities of Essex and Sheffield investigates ways of quantitative description and accurate, transparent modelling of robot-environment interaction. Transparent, analysable models allow the evaluation of robot controllers with regard to issues such as stability, relevance of individual sensor perceptions for the control task at hand, and quantitative compari...

The purpose of this study was to investigate the relationship between stock futures fall risk with non-transparent financial reporting at three levels of size, efficiency and return on equity, in the period 2010 to 2014 was in Tehran Stock Exchange. The population of the study are all companies listed in Tehran Stock Exchange. Data collected and calculated by using Excel software Eviews 7 been ...

1: Given the predictions of increased drought probabilities under various climate change scenarios, there have been numerous experimental field studies simulating drought using transparent roofs in different ecosystems and regions. Such roofs may, however, have unknown side effects, called artifacts, on the measured variables potentially confounding the experimental results. A roofed control al...

A time delay estimation(TDE) method for MIMO systems, using combined continuous wavelet transform(CWT) and cross correlation method, is proposed. By calculating and handling the cross correlation between the CWT coefficients of system input and output data, a series of time delays over scales (frequencies) are calculated and an unbiased estimation is deduced from them. The TDE method under clos...
