The current paper describes the successful attempt to simulate coupled fluid structure interaction of a 3D solid object using open source software. Often the design of hydrodynamic appendages is performed separately by CFD and FEM simulations. The coupling of structural deformation with fluid dynamic pressure is generally done explicitly with a loo...

Often the design of hydrodynamic appendages is performed separately by CFD and FEM simulations. The coupling of structural deformation with fluid dynamic pressure is generally done explicitly with a loose coupling implementation between engineers of different departments. In the present work we propose a tight coupling CFD+FEM solver solution where...

In order to develop efficient offshore wind turbines, it is necessary to mitigate the effect of the turbine motion due to sea waves. In this regard, numerical modeling becomes of great interest since it can provide useful information that cannot be easily collected by means of experimentation; besides, numerical models are cheaper, more flexible an...

The present manuscript describes a computational model employed to characterize the performance and emissions of a commercial marine diesel engine. This model analyzes several pre-injection parameters, such as starting instant, quantity, and duration. The goal is to reduce nitrogen oxides (NOx), as well as its effect on emissions and consumption. S...

The present work proposes several modifications to optimize both emissions and consumption in a commercial marine diesel engine. A numerical model was carried out to characterize the emissions and consumption of the engine under several performance parameters. Particularly, five internal modifications were analyzed: water addition; exhaust gas reci...

The software library preCICE allows to connect single physics solvers to perform mul-tiphysics cosimulations in a partitioned way. We interfaced preCICE with the multibody dynamics software MBDyn and assessed its performance with the set of well-known benchmarks proposed by Turek and Hron. The setup consists of a laminar incompressible flow around...

We consider the problem of detecting mitotic figures in breast cancer histology slides. We investigate whether the performance of state-of-the-art detection algorithms is comparable to the performance of humans, when they are compared under fair conditions: our test subjects were not previously exposed to the task, and were required to learn their...

In this paper we present an application of Reinforcement Learning (RL) methods in the field of robot control. The main objective is to analyze the behavior of batch RL algorithms when applied to a mobile robot of the kind called Mobile Wheeled Pendulum (MWP). In this paper we focus on the common problem in classical control theory of following a re...

The paper presents the application of a genetic algorithm to determine strategies for disassembly of products that have reached the end of their life. First, a general outline of the proposed methodology is provided and the features and specific properties of the genetic algorithm are described. Then an analysis of the algorithm's behaviour is carr...
