A degradação da paisagem urbana e do património dos núcleos históricos é uma problemática complicada na medida em que a cidade é um sistema complexo que engloba a vertente económica, social e ambiental. Da articulação ...

To simulate the gas metal arc welding (GMAW) process in two ASTM A36 steel plates a finite element numerical model was developed, to obtain the corresponding residual stresses and deformations. The welding process was ...

This paper presents the feasibility study of an under-actuated parallel manipulator with 6-PUS topology, destined to handle work-tables in CNC machine tools. The proposed device exploits the fact that, in such an application, ...

In this paper a one-phase Stefan problem with size-dependent thermal conductivity is analysed. Approximate solutions to the problem are found via perturbation and numerical methods, and compared to the Neumann solution for ...

Propeller optimisation is always the focus of the propeller design process, as such process is aimed at finding the best compromise between often conflicting objectives accounting for many design constraints. The use of ...

O tema do presente estudo é a preservação da Paisagem Cultural enquanto forma inovadora de ensejar a proteção e a gestão do patrimônio cultural. Este artigo pretende apresentar as questões problematizadas para a proteção ...

Este artigo divulga a importância da preservação da paisagem do centro histórico das cidades por meio da conservação do patrimônio histórico construído, o qual se caracteriza como um atributo para o desenvolvimento do ...

A parallelizable algorithm to compute invariant tori of high-dimensional dissipative systems, obtained upon discretization of PDEs is presented. The size of the set of equations to be solved is only a small multiple of the ...

We present a Computational Fluid Dynamics (CFD) modeling strategy for onshore wind farms aimed at predicting and opti- mizing the production of farms using a CFD model that includes meteorological data assimilation, complex ...
