Zusammenfassung. Eine wichtige Frage in der mobilen Robotik ist die sichere Navigation in unbekannten Umgebungen unter der Anwendung preiswerter Sensorik. Solch eine Navigation kann ein künstliches Neuronales Netz (kNN) übernehmen, welches die Kopplung der Sensoren des Roboters mit dessen Antriebssystem herstellt. ” Neuro Evolution of Augmenting Topologies“ (NEAT) von Stanley und Miikkulainen [...

This paper is inspired by that of Boston and Mazur [B-M], and work on this problem was begun when the author was a graduate student of Barry Mazur (supported by an NSF Graduate Fellowship). In the paper [B-M], the authors study the deformation theory of a certain type of S3-extensions of Q, which they term neat, and more specifically that of generic S3-extensions, which satisfy an additional co...

A series of 1H amorphous tri-phenyl pyridine (HAPPY) dyes have been synthesized from luminescent triphenyl-group-containing 2-methyl-6-styryl-substituted-4H-pyran-4-ylidene derivatives in reactions with benzylamine and investigated for suitability as solution-processable light-emitting medium components thin films amplified spontaneous emission (ASE). Conversion a 4H-pyrane ring into 1H-pyridin...

This article presents a "Hybrid Self-Attention NEAT" method to improve the original NeuroEvolution of Augmenting Topologies (NEAT) algorithm in high-dimensional inputs. Although NEAT has shown significant result different challenging tasks, as input representations are high dimensional, it cannot create well-tuned network. Our study addresses this limitation by using self-attention an indirect ...

Herewith we report the first attempt towards non-covalent immobilization of Trametes versicolor laccase on neat and magnetically responsive highly porous polyamide 6 (PA6) microparticles their application for catechol oxidation. Four supports, namely PA6 such carrying Fe, phosphate-coated Fe Fe3O4 cores were synthesized in suspension by activated anionic ring-opening polymerization (AAROP) ?-ca...

we introduce center-like subsets z*(r,f), z**(r,f) and z1(r,f), where r is a ring and f is a map from r to r. for f a derivation or a non-identity epimorphism and r a suitably-chosen prime or semiprime ring, we prove that these sets coincide with the center of r.
