The uses of MCM-41 as adsorbent have been studied as an alternative substitution of activated carbon for theremoval dyes. This adsorbent was prepared at laboratory by authors. Adsorption of safranine on MCM-41was studied to examine adsorption thermodynamics. In this study was investigated the effect of proccesparameters like pH, initial dye concentration, temperature and adsorbent mass. MCM-41,...

Purpose Utilising a database that distinctly classifies firm-level ESG (environmental, social and governance) news sentiment as positive or negative, the authors examine information flow between two types of stock returns for 20 companies listed on Johannesburg Stock Exchange 2015 2021. Design/methodology/approach The use Shannonian transfer entropy to whether significantly flows from modified ...

We propose a non-Gaussianity measure of multimode quantum state based on the negentropy quadrature distributions. Our satisfies desirable properties as measure, i.e., faithfulness, invariance under Gaussian unitary operations, and monotonicity channels. Furthermore, we find quantitative relation between our previously proposed measures defined via relative entropy Hilbert-Schmidt distance. This...

With the rapid growth of digital music today, due to complexity itself, ambiguity definition category, and limited understanding characteristics human auditory perception, research on topics related automatic segmentation is still in its infancy, while infancy. Segmentation a prerequisite for fast effective retrieval resources, potential application needs are huge. Therefore, have important val...

Assessing the safety status of cranes is an important problem. To overcome the inaccuracies and misjudgments in such assessments, this work describes a safety assessment method for cranes that combines entropy and cumulative prospect theory. Firstly, the proposed method transforms the set of evaluation indices into an evaluation vector. Secondly, a decision matrix is then constructed from the e...

The Kolmogorov-Sinai entropy is a far reaching dynamical generalization of Shannon entropy of information systems. This entropy works perfectly for probability measure preserving (p.m.p.) transformations. However, it is not useful when there is no finite invariant measure. There are certain successful extensions of the notion of entropy to infinite measure spaces, or transformations with ...

Health monitoring of world economy is an important issue, especially in a time of profound economic difficulty world-wide. The most important aspect of health monitoring is to accurately predict economic downturns. To gain insights into how economic crises develop, we present two metrics, positive and negative income entropy and distribution analysis, to analyze the collective "spatial" and tem...
