The berth allocation and quay crane assignment problem with crane travel and setup times
(Elsevier, 2024-02)
In this paper, we propose a new approach for including quay crane travel and setup times in the berth allocation and quay crane assignment problem. We first develop a new mixed integer linear programming model (MILP) for ...

Enhancing nonlinear solvers for the Navier–Stokes equations with continuous (noisy) data assimilation
(Elsevier, 2024-05)
We consider nonlinear solvers for the incompressible, steady (or at a fixed time step for unsteady) Navier–Stokes equations in the setting where partial measurement data of the solution is available. The measurement data ...

On the integrability problem for the Hopf-zero singularity and its relation with the inverse Jacobi multiplier
(Elsevier Inc., 2021)
In this paper we use the orbital normal form of the nondegenerate Hopf-zero singularity to obtain necessary conditions for the existence of first integrals for such singularity. Also, we analyze the relation between the ...

A mixed integer linear programming model for resolution of the antenna-satellite scheduling problem
(Institute of Electrical and Electronics Engineers, 2024-02)
This article deals with one of the types of “Satellite Range Scheduling” problems arising in Earth Observation Satellite operations, Antenna-Satellite Scheduling. Given a set of satellites, a set of available antennas and ...

Discussion on different numerical treatments on the loss of hyperbolicity for the two-layer shallow water system
(Elsevier, 2023)
This paper focus on the numerical approximation of two-layer shallow water system. First, a new approximation of the eigenvalues of the system is proposed, which satisfies some interesting properties. From this approximation, ...

On the convergence order of the finite element error in the kinetic energy for high Reynolds number incompressible flows
(Elsevier, 2021-11)
The kinetic energy of a flow is proportional to the square of the L2(Ω) norm of the velocity. Given a sufficient regular velocity field and a velocity finite element space with polynomials of degree r , then the best ...

Separability, Boxicity, and Partial Orders
(Springer, 2023)
A collection S = {Si,..., Sn} of disjoint closed convex sets in Rd is separable if there exists a direction (a non-zero vector) −→v of Rd such that the elements of S can be removed, one at a time, by translating them an ...

A novel methodology for public management of annual greenhouse gas emissions in the European Union
(Elsevier, 2023)
Global warming and climate change, as a result of greenhouse gas emissions, pose a major threat to the international community; therefore, such emissions must be reduced by moving to clean energy resources. In this paper, ...

Constrained many-to-many point matching in two dimensions
(Springer, 2024-01-26)
In the minimum-weight many-to-many point matching problem, we are given a set R of red points and a set B of blue points in the plane, of total size N, and we want to pair up each point in R to one or more points in B and ...

A new commutativity property of exceptional orthogonal polynomials
(Springer, 2024-03-29)
We exhibit three examples showing that the “time-and-band limiting” commutative property found and exploited by D. Slepian, H. Landau and H. Pollak at Bell Labs in the 1960s, and independently by M. Mehta and later by C. ...
