Heterogeneous photocatalysis under visible light irradiation allows performing of selective oxofunctionalization hydrocarbons at ambient temperature and pressure, using molecular oxygen as a sacrificial reagent potential use sunlight sustainable low-cost energy source. In the present work, photocatalytic material based on heterojunction titanium dioxide bismuth oxyiodide was used photocatalyst ...

The polarity shift problem is amajor factor that affects classification performance ofmachinelearning-based sentiment analysis systems. In this paper, we propose a three-stage cascade model to address the polarity shift problem in the context of document-level sentiment classification. We first split each document into a set of subsentences and build a hybrid model that employs rules and statis...

This paper describes a new approach for precise image shift detection between two images. The approach is based on an analysis of the phase difference spectrum between two images. Image shifts are directly evaluated from the phase difference spectrum without Fourier inversion. The cross s~ectrum is utilized as the weight parameter distribution. Synthetic and real images of typical image pattern...
