An adaptive finite element strategy is employed to solve the Perona-Malik model as modified by Catté, Lions, Morel and Coll for image processing by (often highly) nonlinear diffusion. FEMLAB® and MATLAB® are used to implement the experiments and they prove to be very suitable tools to run this type of problem. Refinement and coarsening of the grids are used as needed and the approach leads to ...

The capillary network is a complex-interconnected structure. A single blood cell traveling from the arteriole to a venule via a capillary bed passes through, on average, 40−100 capillary segments. The cardiovascular systems responsible of delivering blood to the tissue under sufficient pressure to exchange materials. This is a two way process, at which nutrients, Oxygen, and other ...

Objective of this contribution is to present a procedure for evaluating second order drift forces on floating bodies, often the most important loading component for mooring design, in case of high waves propagating in relatively shallow water depths. The non linearity associated to this condition, which is typical of installations involving wave energy converters, makes this problem particularly ...

During the past 50 years, Computational Science has developed as its own branch of mathematics. This development was mainly initiated by the progress of modern computers. Todays modeling of physical phenomena must not only account for the computational time but also the time engineers spend on setting up the computation. This in turn has introduced new fields, such as human interaction, to ...

The paper presents the development of a method that determines building material and surface properties using relative simple and low-budget experiments, The method comprehends an optimal design of an experimental set up for smart determination of heat and moisture properties using both normal and inverse modeling techniques. It is concluded that the suggested methodology of the inverse ...

As embalagens de produtos alimentícios são hoje em dia predominantemente feitas com cartão tipo LPB (Liquid Packaging Board) e usualmente estocadas de forma empilhada, tanto nas prateleiras como nos depósitos dos supermercados. O LPB é um compósito multicamadas de construção complexa, envolvendo, tipicamente, papel produzido com fibras virgens, polietileno e alumínio. O alimento líquido ...

Ensuring the quality of underground water and controlling its quantity is of major concern for the population. Therefore, this subject attracts many students from different specialties at different levels of their curriculum. In fact, the pedagogic objectives of the course may be different according to the level or/and interest of the students and COMSOL is used due to its versatility. In this ...

Partial differential equations which exhibit solutions that are spatial temporal patterns are often found in biological and chemical systems, e.g. when describing pattern formation in reaction-diffusion systems.Special classes of such patterns are relative equilibria and relative periodic orbits, which are solutions that in an appropriately co-moving frame of reference are stationary and ...

Bone resorption around hip stems, in particular periprosthetic bone loss, is a common observation post-operatively. A number of factors influence the amount of bone loss over time and the mechanical environment following total hip replacement (THR) is important. Conventional long stem prostheses have been shown to transfer loads distally, resulting in bone loss of the proximal femur. More ...
