Uncertainty quantification and efficient timedependent reliability analysis of stochastic dynamic systems Dr. Marius Bittner (Institute for Risk and Reliability, Leibniz University, Hannover)  This presentation introduces a framework for risk assessment in structural engineering, focusing on dynamic systems with uncertainties. It addresses two main challenges: first, improving the efficiency and accuracy of the Probability Density Evolution Method (PDEM) through the Subset supported Point Selection (S-PS) method, which creates sample sets that better capture critical system behavior. Second, it proposes the use of Evolutionary Power Spectral Density (EPSD) functions, specifically the Relaxed Evolutionary Power Spectral Density (REPSD) function, to model time-varying phenomena like earthquakes or strong winds. By incorporating real data, the REPSD function enhances simulations and analyses, making risk assessments more accurate and reliable for safer design practices in structural engineering.   Webcast link: https://lnkd.in/dc4UNq6B Mais Informações : herbert@mecanica.ufrgs.br Data: 27 de Novembro de 2024 Horário : 10:00h – 11:00h Local: Mezanino GMAp – Eng.

Efficient diagnostics of complex mechanical systems Dr. Jan Grashorn (Institute for Risk and Reliability, Leibniz University, Hannover)  The presentation focuses on fault diagnosis in engineering systems using inverse modeling, where data and computational models are leveraged to infer system states. To address model inaccuracies and sensor noise, a stochastic framework is employed to quantify uncertainties in both models and measurements, providing a more robust approach by capturing a range of possible outcomes and their probabilities. Inverse problems are often ill-posed, but probabilistic methods allow for evaluating multiple models and states to identify the most likely scenarios. The paper explores efficient alternatives to computationally expensive Bayesian methods, particularly through recent advances in optimal transport. By using transport maps—specifically polynomial-based maps, with flexibility for other functions like neural networks—a variational approach is introduced for Bayesian updating, significantly reducing computational costs while maintaining accuracy in structural health monitoring and parameter updating for dynamical systems.   Webcast link: https://lnkd.in/dc4UNq6B Mais Informações: herbert@mecanica.ufrgs.br Data : 25 de Novembro de 2024 Horário: 14:00h – 15:00h Local : Mezanino GMAp – Eng.

Workshop on Uncertainty Quantification utilizing the Julia programming language package Dr. Marius Bittner and Dr. Jan Grashorn (Institute for Risk and Reliability, Leibniz University, Hannover) This presentation introduces a Julia package for uncertainty quantification that offers a range of functionality, including simulation-based reliability analysis, Monte Carlo and Quasi Monte Carlo simulations (e.g., Sobol, Halton, Latin Hypercube, Lattice Rule), Line Sampling, Subset Simulation, and various sensitivity analysis methods (e.g., Sobol indices). It supports metamodeling techniques like Polyharmonic splines, Polynomial Chaos Expansion, and Response Surface Methodology. The package also allows integration with third-party solvers and high-performance computing (HPC) via slurm. The workshop associated with the package consists of three parts: an introduction to Julia programming for uncertainty quantification using the UncertaintyQuantification.jl package, an overview of Bayesian Model Updating Techniques, and a guide to basic reliability analysis, including using third-party solvers such as OpenSees.

Nota de Pesar É com grande pesar que comunicamos o falecimento do Prof. Marco Tullio Mena Barreto de Vilhena, da Universidade Federal do Rio Grande do Sul. O Prof. Vilhena era formado em Eng. Civil pela UFRGS (1968), mestrado pelo Instituto Militar de Engenharia e pelo Instituto de Física da UFRGS. Foi o 1° doutor da Escola de Engenharia da UFRGS, pelo Programa de Pós-Graduação em Engenharia Mecânica (PROMEC), em 1986. Foi professor Titular da UFRGS junto ao extinto Departamento de Engenharia Nuclear. Estava aposentado e integrava o corpo docente do PROMEC como professor convidado. Tinha experiência na área de Engenharia Mecânica, com ênfase em Fenômenos de Transporte, atuando em temas relacionados à equação de transporte e simulação da dispersão de poluentes. O Prof. Vilhena foi o mentor do método LTSN, um método de solução analítica para o conjunto de equações diferenciais ordinárias resultantes da aproximação de ordenadas discretas SN da equação unidimensional de transporte de nêutrons. O método foi mais tarde generalizado e aplicado para um grande número de aplicações em Física e Engenharia. Teve sempre uma grande destreza em tudo que se relacionava a equações integrais e transformada de Laplace, sendo reconhecido em muitos meios internacionais pelo seu conhecimento e por seu jeito cativante. O Prof. Vilhena orientou dezenas de alunos, e é o responsável direto pela formação de grandes doutores e muitos docentes em inúmeras universidades no Brasil e no exterior. Sua influência, seja por suas orientações, seja por seus livros, ou por suas publicações, é incalculável. Sua falta será sempre sentida, mas sua presença perdurará por muitas décadas através das gerações de alunos e professores que tiveram a sorte de compartilhar seu conhecimento e amizade. #promecufrgs #posgraduacao #posgraduacaoengenhariamecanica #ufrgs #engenhariamecanica #engmec #engmecanica #mestrado #mestradoufrgs #doutorado #doutoradoufrgs

Palestra The AutoSapiens Platform for Autonomous Driving Lecturer: Prof. PhD. Gianluca Pepe Sapienza Università di Roma, e-mail: gianluca.pepe@uniroma1.it AutoSapiens is an advanced platform for the development of autonomous vehicles, created by the Mechatronics and Vehicle Dynamics Lab at the University of Sapienza in Rome. The platform serves as a testing ground for advanced control strategies and obstacle avoidance technologies. At the core of the system is a "vehicle-in-the-loop" equipped with actuators for steering, braking, and acceleration, along with an array of sensors capable of real-time monitoring of both the vehicle's dynamics and the surrounding environment. AutoSapiens enables the testing of various control systems, ranging from stability and suspension control to the integration of smart tires and autonomous driving technologies. One of the platform’s distinctive features is vehicle-to-vehicle (V2V) communication, which allows the exchange of critical data such as position and speed, enhancing safety during navigation in complex environments. The innovative architecture supports advanced Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) simulations, creating a realistic testing environment that integrates vehicles and aerial support drones, alongside the real-time simulation of urban scenarios rendered using advanced graphic engines.
