Designing ecotourism routes with time-dependent benefits along arcs and waiting times at nodes
(MDPI, 2024-02-20)
Ecotourism routes serve as powerful tools for fostering environmental awareness. To achieve this, it is crucial to design itineraries within natural parks that strike a balance between visitor experience and ecological ...

On the connectivity and restricted edge-connectivity of 3-arc graphs
(Elsevier, 2014-01-10)
A 3 − arc of a graph G is a 4-tuple (y, a, b, x) of vertices such that both (y, a, b) and (a, b, x) are paths of length two in G. Let ←→G denote the symmetric digraph of a graph G. The 3-arc graph X(G) of a given graph ...

Algorithm for planning faster routes in urban networks with time-dependant arcs and the possibility of introducing waiting periods at nodes
(WIT Press, 2022)
Navigation systems implemented in mobile devices allow users to search for the shortest routes between pairs of points. Many of the existing commercial products assume in a simplified way that the travel time to cross each ...

From octonions to composition superalgebras via tensor categories
(European Mathematical Society, 2024)
The nontrivial unital composition superalgebras, of dimension 3 and 6, which exist only in characteristic 3, are obtained from the split Cayley algebra and its order 3 automorphisms, by means of the process of semisimplification ...

Exact cost minimization of a series-parallel reliable system with multiple component choices using an algebraic method
(2013-11)
The redundancy allocation problem is formulated minimizing the design cost for a series-parallel system with multiple component choices while ensuring a given system reliability level. The obtained model is a nonlinear ...

Parallel homological calculus for 3D binary digital images
(Springer, 2024-01-29)
Topological representations of binary digital images usually take into consideration different adjacency types between colors.Within the cubical-voxel 3D binary image context, we design an algorithm for computing the ...

Simplicial-Map Neural Networks Robust to Adversarial Examples
(MDPI [Commercial Publisher], 2021-01-15)
Broadly speaking, an adversarial example against a classification model occurs when a small perturbation on an input data point produces a change on the output label assigned by the model. Such adversarial examples represent ...

Modelling of bedload sediment transport for weak and strong regimes
(Springer, 2021)
A two-layer shallow water type model is proposed to describe bedload sediment transport for strong and weak interactions between the fluid and the sediment. The key point falls into the definition of the friction law between ...

Non-hydrostatic layer-averaged approximation of Euler system with enhanced dispersion properties
(Springer, 2023-05-10)
A new family of non-hydrostatic layer-averaged models for the non-stationary Euler equations is presented in this work, with improved dispersion relations. They are a generalisation of the layer-averaged models introduced ...

Multilayer models for hydrostatic Herschel-Bulkley viscoplastic flows
(Elsevier, 2023-06-01)
Starting from Navier-Stokes’ equation we derive two shallow water multilayer models for yield stress fluids, depending on the asymptotic analysis. One of them takes into account the normal stress contributions, making ...
