Symmetric graphs have non-trivial automorphism groups. This article starts with the proof that all partition comparison measures we have found in the literature fail on symmetric graphs, because they are not invariant with regard to the graph automor

The analysis of symmetry is a main principle in natural sciences, especially physics. For network sciences, for example, in social sciences, computer science and data science, only a few small-scale studies of the symmetry of complex real-world graph

Access control mechanisms are needed in almost every system nowadays to control what kind of access each user has to which resources and when. On the one hand access control systems need to be flexible to allow the definition of the access rules that

The study evaluates the performance of laboratory, single-layered particleboards made out of fructose-hydroxymethylfurfural-bishexamethylenetriamine (SusB) adhesive as a sustainable alternative. Several production parameters such as mat moisture cont

A batch reaction system (volume 1 L) for scaled-up production of 5-HMF-based adhesive precursor solutions from industrially available fructose syrup was developed. The stabilizing effect of sodium dithionite addition was demonstrated. With this syste

Dark matter or violations of the Einstein equivalence principle influence the motion of atoms, their internal states as well as electromagnetic fields, thus causing a signature in the signal of atomic detectors. To model such new physics, we introduc

Incorporating Financial News for Forecasting Bitcoin Prices Based on Long Short-Term Memory Networks
Publikováno v:
SSRN Electronic Journal.
In this paper we investigate how a deep learning machine learning model can be applied to improve Bitcoin price forecasting and trading by incorporating unstructured information from financial news. The two-stage model we propose outperforms other ma

The Petersen graph has been of long term interest to many graph theorists because of its appearance as counterexample in many places. In this contribution we use the Petersen graph—because of its transitivity and its large, but not too large automo

Increasingly, retailers rely on interactive technologies to improve consumers' shopping experiences. On the one side, interactive kiosks and smart mirrors make use of dedicated devices and software to explain, configure, and recommend products. On th
