On the sub–diffusion fractional initial value problem with time variable order

open access: yesAdvances in Nonlinear Analysis, 2021
We consider a fractional derivative with order varying in time. Then, we derive for it a Leibniz' inequality and an integration by parts formula. We also study an initial value problem with our time variable order fractional derivative and present a ...

Regularization for design

open access: yes53rd IEEE Conference on Decision and Control, 2014
When designing controllers for large-scale systems, the architectural aspects of the controller such as the placement of actuators, sensors, and the communication links between them can no longer be taken as given. The task of designing this architecture is now as important as the design of the control laws themselves.

On the Duality of Regular and Local Functions

open access: yesMathematics, 2017
In this paper, we relate Poisson’s summation formula to Heisenberg’s uncertainty principle. They both express Fourier dualities within the space of tempered distributions and these dualities are also inverse of each other.

A new characterization of fuzzy ideals of semigroups and its applications

open access: yesAutomatika, 2021
In this paper, we develop a new technique for constructing fuzzy ideals of a semigroup. By using generalized Green's relations, fuzzy star ideals are constructed.

Temporal Graphs and Temporal Network Characteristics for Bio-Inspired Networks during Optimization

open access: yesApplied Sciences, 2022
Temporal network analysis and time evolution of network characteristics are powerful tools in describing the changing topology of dynamic networks. This paper uses such approaches to better visualize and provide analytical measures for the changes in ...

Regular Partitions of Regular Graphs [PDF]

open access: yesCanadian Mathematical Bulletin, 1978
In the study of the combinatorial structure of edge-graphs of convex polytopes one may ask whether a given graph possesses a partition consisting of certain kinds of subgraphs.In this paper we describe some special partitions of 3-valent and 4-valent graphs.

Iterative regularization for convex regularizers

open access: yes, 2020
We study iterative regularization for linear models, when the bias is convex but not necessarily strongly convex. We characterize the stability properties of a primal-dual gradient based approach, analyzing its convergence in the presence of worst case deterministic noise.

Regular Model Checking with Regular Relations [PDF]

open access: yes, 2021
Regular model checking is an exploration technique for infinite state systems where state spaces are represented as regular languages and transition relations are expressed using rational relations over infinite (or finite) strings. We extend the regular model checking paradigm to permit the use of more powerful transition relations: the class of ...
