Computational modelling suggests complex interactions between interstitial flow and tumour angiogenesis
(Royal Society, 2018)[Abstract:] Angiogenesis, the growth of capillaries from pre-existing ones, plays a key role in cancer progression. Tumours release tumour angiogenic factors (TAFs) into the extracellular matrix (ECM) that trigger angiogenesis ... -
Computer analysis of earthing systems in horizontally or vertically layered soils
(Elsevier, 2001)[Abstract] The main objectives of grounding systems are to guarantee the personal safety, the equipment protection and the continuity of the power supply. To attain these goals, the potential distribution on the earth ... -
Computer software for analysis and design optimization of power transmission structures by simulated annealing and sensitivity analysis
(Springer, 2021)[Abstract:] This paper presents a computer software for the optimization of power transmission structures. The software employs a modified version of the Simulated Annealing algorithm that has been proven effective in large ... -
Estimation of long-term fatigue damage of fixed substructures using fully-coupled models and non-linear dynamic analysis
(Elsevier, 2020)[Abstract:] Typical industry models for Offshore Wind Turbines with fixed substructures are based on decoupled models between the wind turbine and the substructure. It is proved that the complete dynamic response of the ... -
Finite volume solvers and moving least-squares approximations for the compressible Navier-Stokes equations on unstructured grids
(Elsevier, 2005)[Abstract] This paper introduces the use of Moving Least-Squares (MLS) approximations for the development of high order upwind schemes on unstructured grids, applied to the numerical solution of the compressible Navier-Stokes ... -

High order finite volume schemes on unstructured grids using Moving Least Squares reconstruction. Application to shallow water dynamics
(John Wiley and Sons, 2005)[Abstract] This paper introduces the use of Moving Least Squares (MLS) approximations for the development of high-order finite volume discretizations on unstructured grids. The field variables and their succesive derivatives ... -
High Order Shape Design Sensitivity: A Unified Approach
(Elsevier, 2000)[Abstract] Three basic analytical approaches have been proposed for the calculation of sen- sitivity derivatives in shape optimization problems. The first approach is based on differentiation of the discretized equations ... -
IGA-based topology optimization in the design of stress-constrained compliant mechanisms
(Springer, 2023)[Abstract:] Topology design of compliant mechanisms has gained wide popularity among the scientific community, and their use in the mechanical engineering field is being of upmost importance. In this paper, an isogeometric ... -
Improved δ-SPH Scheme With Automatic and Adaptive Numerical Dissipation
(MDPI, 2020)[Abstract] In this work we present a δ-Smoothed Particle Hydrodynamics (SPH) scheme for weakly compressible flows with automatic adaptive numerical dissipation. The resulting scheme is a meshless self-adaptive method, in ... -
Krein’s theorem in the context of topological abelian groups
(MDPI, 2022)[Abstract:] A topological abelian group G is said to have the quasi-convex compactness property (briefly, qcp) if the quasi-convex hull of every compact subset of G is again compact. In this paper we prove that there exist ... -
MLS-SPH-ALE: A Review of Meshless-FV Methods and a Unifying Formulation for Particle Discretizations
(Springer, 2023)[Abstract:] Mesh-based and particle methods were conceived as two different discretization strategies to solve partial differential equations. In the last two decades computational methods have diversified and a myriad of ... -
