Abstract:Flashed glasses are composed of a base glass and a thin colored layer and have been used since medieval times in stained glass windows. Their study can be challenging because of their complex composition and multilayer structure. In the present work, a set of optical and spectroscopic techniques have been used for the characterization of a representative set of flashed glasses commonly used in the manufacture of stained glass windows. The structural and chemical composition of the pieces were investigated by optical microscopy, field emission scanning electron microscopy-energy dispersive X-ray spectrometry (FESEM-EDS), UV-Vis-IR spectroscopy, laser-induced breakdown spectroscopy (LIBS), and laser-induced fluorescence (LIF). Optical microscopy and FESEM-EDS allowed the determination of the thicknesses of the colored layers, while LIBS, EDS, UV-Vis-IR, and LIF spectroscopies served for elemental, molecular, and chromophores characterization of the base glasses and colored layers. Results obtained using the micro-invasive LIBS technique were compared with those retrieved by the cross-sectional technique FESEM-EDS, which requires sample taking, and showed significant consistency and agreement. In addition, LIBS results revealed the presence of additional elements in the composition of flashed glasses that could not be detected by FESEM-EDS. The combination of UV-Vis-IR and LIF results allowed precise chemical identification of chromophores responsible for the flashed glass coloration.Keywords: flashed glass; multianalytical characterization; chemical composition; chromophores; laser-induced breakdown spectroscopy; thickness measurements
The illustrations are only intended to give a first general impression of the various possibilities of flashed glass. The size of the individual sheets is approx. 60x90 cm (24" x 36"), the thickness is approx. 3 mm. Unfortunately, the printing technology does not allow exact color representation.
How is this helpful? Well, it shows you the anagrams of flashed scrambled in different ways and helps you recognize the set of letters more easily. It will help you the next time these letters, F L A S H E D come up in a word scramble game.
For this project my .bin file is about 18k and my .elf file is about 1.8M. I know the whole .elf doesn't get flashed onto the MCU, but how much of it does? Is it just the size of the .bin that gets flashed, or is there some extra debug information as well?
The size of the .bin is probably the size of what gets flashed onto the MCU. (I say "probably" because it's possible that the .bin file is padded with some empty space depending on how it was created.)
The first aim of our study was to test visual recognition memory for complex natural scenes flashed for only 20 ms. To further test the effect of repetition on memory performance, one group of participants saw the to-be-recognized images only once and a second group saw the same images set over several days for a cumulative time of 440 ms. Such short stimulus presentation time has never been used in long-term memory recognition. Indeed, it reduces the stimulus energy and prevents the possibility of making saccades to encode details about the stimuli. 2b1af7f3a8
