Evaluating aesthetic value of digital photographs is a challenging task, mainly due to the subjective manner of the process. In this paper, we propose to approach this problem using deep convolutional neural networks. Using a dataset of over 1.7 million photos collected from Flickr, we train and evaluate a deep learning model whose goal is to classify photographs by analysing their aesthetics. The...
In this paper, we report on measurements of absorption spectra of hexogen, penthrite, and octogen. The measurements were carried out by means of time domain spectroscopy and compared to spectra obtained from a setup, which bases on an optical parametric oscillator combined with a Golay cell. For time domain spectroscopy measurement, Teraview TPS 3000 unit with accessories in transmission configuration...
In this paper we report on measurement of spectra of commonly applied explosives, some materials which can be used for manufacture of explosive and THz simulants of explosives in transmission mode. Substances were prepared as pellets, and the measurements were performed using the Time Domain Spectroscopy system in the range 0.1–3.0 THz.
We report on influence of phlegmatization of two explosives: hexogen and octogen on their spectra in 0.5-5.0 THz range. Measurements were carried out by means of Fourier Transform Spectrometry. Increase in attenuation is observed for both materials.
W artykule opisano technikę pomiarów spektrometrycznych w dziedzinie czasu (TDS-THz). Przedstawiono układ badawczy do tego typu pomiarów oraz omówiono metodykę przygotowania próbek materiałów niebezpiecznych. Przedstawiono również wyniki pomiarów uzyskane tą metodą.
