A Unified Benchmarking Platform for UQ Algorithms in UQLab
(2024)Thorough validation and benchmarking against the state-of-the-art are critical components in the development of novel algorithms and tools. Nevertheless, the comprehensive performance comparison between different solutions to the same problem is still sparse in the literature, mostly relegated to dedicated review studies rather than a standard practice. This is especially noticeable in the field of uncertainty quantification, where algorithm ...Other Conference Item -
UQLab & UQ[py]Lab - project updates and outlook
(2023)The adoption of advanced uncertainty quantification techniques is steadily increasing throughout the academic and industrial applications landscape. The assessment of uncertainty in technological systems of societal relevance (e.g. in civil and aerospace engineering) is being gradually mandated, or at least included in engineering construction codes all around the world. In parallel, the design and maintenance of renewable energy systems ...Other Conference Item -
Surrogate modelling for stochastic simulators
(2023)Computational models, a.k.a. simulators, are used in all fields of engineering and applied sciences to help design and assess complex systems. Advanced analyses such as optimization or uncertainty quantification, which require repeated runs by varying input parameters, cannot be carried out with brute force methods such as Monte Carlo simulation due to computational costs. Thus the recent development of surrogate models such as polynomial ...Other Conference Item -
Defining what is a probability of failure for systems modelled by stochastic simulators
(2023)Reliability analysis is a field of uncertainty quantification primarily concerned with estimating the probability that a system response exceeds a critical threshold, resulting in failure. By design, such a probability of failure is small. Consequently, accurately computing it requires many evaluations of the so-called limit state function, a computational model that classifies whether the system fails or not, and that is often expensive ...Other Conference Item -
Different methods for increasing transmission in cyclotron-based proton therapy facilities
(2022)In proton therapy (PT), high dose rates could allow efficient utilization of motion mitigation techniques for moving targets, and potentially enhance normal tissue sparing due to the FLASH effect. Cyclotrons are currently the most common accelerator for PT, accounting for two-thirds of the total installations. However, for cyclotron-based facilities, high dose rates are difficult to reach for low energy beams, which are generated passing ...Other Conference Item -

The Advocacy Planning and the Civil Rights Movement in the United States: The Architects’ Renewal Committee and the Democratization of Urban Planning
(2021)This paper takes as its point of departure advocacy planning approaches’ consideration that urban renewal is incompatible with any kind of socially effective urban planning. It focuses on analysing the Architects’ Renewal Committee in Harlem (ARCH), the first organisation solely devoted to advocacy planning in the United States, and places particular emphasis on the critiques of urban renewal strategies in the late 1960s in the North-Eastern ...Other Conference Item -
Recent developments on surrogate models for stochastic simulators
(2021)Computational models, a.k.a. simulators, are used in all fields of engineering and applied sciences to help design and assess complex systems in silico. Advanced analyses such as optimization or uncertainty quantification, which require repeated runs by varying input parameters, cannot be carried out with brute force methods such as Monte Carlo simulation due to computational costs. Thus the recent development of surrogate models such as ...Other Conference Item
