In this work, we address the implementation and performance of inexact Newton–Krylov and
quasi-Newton algorithms, more specifically the BFGS method, for the solution of the …

In minimally-invasive liver surgery interventions, augmented reality systems aim to help
medical staff by tracking the motion of the patient's liver in real time. To compute the updated …

We address the problem of organ registration in augmented surgery, where the deformation
of the patient's organ is reconstructed in real-time from a partial observation of its surface …

Quasi-Newton-based nonlinear finite element methods were extensively studied in the
1970s and 1980s. However, they have almost disappeared due to their poorer convergence …

In recent years, many modern optimization techniques have been developed in the field of
mathematical programming. The feasibility of applying these techniques to the …

A family of non‐linear solution methods is investigated based on limited‐memory quasi‐
Newton updates. Depending upon the number of updates and the updating formula, a …

To optimize the design of roll pass schedules and control the mechanical and metallurgical
properties of plate rolled aluminium, a thorough knowledge of metal flow and microstructural …

We address the problem of organ registration in augmented surgery, where the deformation
of the patient's organ is reconstructed in real-time from a partial observation of its surface …

A finite element formulation to deal with the flow of metal that includes high speed effects is
presented. The deformation process of the metal is treated using the rigid-plastic or the rigid …

The present investigation describes the combined effects of dynamic loading, viscoplasticity
and temperature on the development of ductile fracture. The model employed to describe …
