Translation invariant transformations of discrete random sets
Proceedings SIBGRAPI'98. International Symposium on Computer Graphics, Image Processing, and Vision (Cat. No.98EX237), 2002Random modeling is an important technique for solving hard problems in coding, quantitative description and restoration of images. In the sixties. Matheron introduced the theory of Random Closed Sets (RACS), that permits the creation of models by morphological transformations of primitive processes.

Translations of the Discrete Bose-Einstein Operators
Journal of Mathematical Physics, 1966The effects on a certain family of representations of the commutation relations of the operator-translations ak → ak + ck, ak* → ak* + ck*, are investigated. Here ak and ak* are the annihilation and creation operators of the representations, the ck are complex numbers (scalar operators), and the representations considered are the discrete ...

Translating Discrete-Time Simulink to Lustre
2003We present a method of translating discrete-time Simulink models to Lustre programs. Our method consists of three steps: type inference, clock inference and hierarchical bottom-up translation. In the process, we formalise typing and timing mechanisms of Simulink. The method has been implemented in a prototype tool called S2L.

Crystal Spacetimes with Discrete Translational Symmetry
2019The aim of this work is to construct exact solutions of Einstein–Maxwell(-dilaton) equations possessing a discrete translational symmetry. We present two approaches to the problem. The first one is to solve Einstein–Maxwell equations in 4D, the second one relies on dimensional reduction from 5D.

Translation invariant quantum walks with discrete symmetries
2018Quantenwalks sind diskrete Zeitentwicklungen von Einteilchen-Gittersystemen, die Konzepte klassischer Random Walks in die Quantentheorie übertragen. Topologische Isolatoren versprechen Randzustände für Transport an Grenzflächen, die topologisch geschützt sind.

Disjoint Hypercyclicity and Weighted Translations on Discrete Groups
Canadian Mathematical Bulletin, 2017Let 1 ≤ p < ∞, and let G be a discrete group. We give a sufficient and necessary condition for weighted translation operators on the Lebesgue space ℓp(G) to be densely disjoint hypercyclic. The characterization for the dual of a weighted translation to be densely disjoint hypercyclic is also obtained.

Translation-invariant data visualization with orthogonal discrete wavelets
IEEE Transactions on Signal Processing, 1998Orthogonal discrete wavelet transforms can be made translation-invariant by adding redundant wavelet coefficients through repeated shifting operations. Orthogonality is lost, but isometry and compact time support can be preserved. The practical application to data visualization of scalograms based on such transforms is discussed and illustrated with ...

Translating Discrete Time SIMULINK to SIGNAL
2014As Cyber Physical Systems (CPS) are getting more complex and safety critical, Model Based Design (MBD), which consists of building formal models of a system in order to be used in verification and correct-by-construction code generation, is becoming a promising methodology for the development of the embedded software of such systems.
