Dynamics of non-convolution operators and holomorphy types
(Academic Press Inc Elsevier Science, 2018-12)
In this article we study the hypercyclic behavior of non-convolution operators defined on spaces of analytic functions of different holomorphy types over Banach spaces. The operators in the family we analyze are a composition ...
Hypercyclic behavior of some non-convolution operators on H(CN)
(Theta Foundation, 2017-01)
We study hypercyclicity properties of a family of non-convolution operators defined on the spaces of entire functions on CN. These operators are a composition of a differentiation operator and an affine composition operator, ...
Strongly Mixing Convolution Operators on Fréchet Spaces of Holomorphic Functions
(Birkhauser Verlag Ag, 2014-11)
A theorem of Godefroy and Shapiro states that non-trivial convolution operators on the space of entire functions on (Formula Presented.) are hypercyclic. Moreover, it was shown by Bonilla and Grosse-Erdmann that they have ...
Gradient direction analysis for contour tracking and local non maximum suppression
(Proceedings of SPIE - The International Society for Optical Engineering, 2022)
Rank-based self-training for graph convolutional networks
(2021-03-01)
Graph Convolutional Networks (GCNs) have been established as a fundamental approach for representation learning on graphs, based on convolution operations on non-Euclidean domain, defined by graph-structured data. GCNs and ...
Convolutional neural networks for automated damage recognition and damage type identification
(John Wiley and Sons Ltd, 2018)
Recurring expenses associated with preventative maintenance and inspectionproduce operational inefficiencies and unnecessary spending. Human inspec-tors may submit inaccurate damage assessments and physically inaccessibl ...
Two-level genetic algorithm for evolving convolutional neural networks for pattern recognition
(IEEE-Inst Electrical Electronics Engineers, 2021)
The aim of Neuroevolution is to nd neural networks and convolutional neural network (CNN)
architectures automatically through evolutionary algorithms. A crucial problem in neuroevolution is search
time, since multiple ...
Implementação computacional para cálculo da convolução de sinais contínuos e discretos no tempo e aplicações
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Computação, 2020-12-03)
The study of signals and systems makes a study field very important for Engineering. It’s
through this kind of study that it’s possible to model, represent, study and understand various
phenomena that occurs in peoples ...
Welland's type inequalities for fractional operators of convolution with kernels satisfying a Hörmander type condition and their commutators
(Taylor & Francis Ltd, 2018-06)
Let μ be a non-negative Ahlfors n-dimensional measure on Rd. In this context we shall consider convolution type operators Tαf = Kα ∗f, 0 <α< n, where the kernels Kα are supposed to satisfy certain size and regularity ...
