Huang, Wenqing (author)The excessive nitrogen in waterbodies, often caused by the discharge of ammonia-rich wastewaters, leads to eutrophication, disrupting aquatic ecosystems. Wastewater treatment plants play an important role in the removal and recovery of nitrogen from wastewater streams, thereby preventing pollution. Air stripping in combination with acid...master thesis 2024

Agante de Carvalho, José Rui (author)Waveriders are high-lifting hypersonic configurations with great potential to become a future reusable launch vehicle concept. However, in a re-entry flight scenario, standard waverider designs face challenges such as stability, controllability, heat load management, and performance at off-design conditions. In this research, a baseline...master thesis 2023

Martorelli, Luca (author)The use of CFD-based optimizations is becoming a standard for turbomachinery design. Although the use of such optimizations can lead to great improvements of the machine performances, there are still several shortcomings in the common design procedure of turbomachines. In fact, this entails the optimization of the component shape, and only a...master thesis 2023

Teixeira, Rui (author), Nogal Macho, M. (author), O'Connor, Alan (author)The present work reviews the implementation of adaptive metamodeling for reliability analysis with emphasis in four main types of metamodels: response surfaces, polynomial chaos expansions, support vector machines, and Kriging models. The discussion presented is motivated by the identified spread and little interaction between metamodeling...journal article 2021

Teixeira, Rui (author), Martinez-Pastor, Beatriz (author), Nogal Macho, M. (author), O'Connor, Alan (author)The present work discusses an innovative approach to metamodeling in reliability that uses a field-transversal rationale. Adaptive metamodeling in reliability is characterized by its large spectra of models and techniques with different assumptions. As a result, the reliability engineer is frequently faced with the highly challenging task of...journal article 2021

Romaniuk, Filip (author)The master's thesis explores the possibilities of reusing abandoned post-industrial structures and objects of architectural heritage. Objects, which are usually difficult to renovate due to high costs and their poor physical condition, could be filled with new inflatable volumes and thus be filled with new space, function, and life. The work is...master thesis 2020

Gupta, Tarang (author)The power of sound is immense. It provides an immersive experience for the user in many different forms, such as noise, melodies, voices or even a song. It is a tricky genre unlike light and temperature, and is highly complex to predict and control the user behavior in terms of sound. Thus, the intention is to correct the acoustics as a post...master thesis 2020

Rotteveel, E. (author)This research focuses on identifying the most important stern shape aspects, with regard to resistance and propulsion power, of inland ships. Such information should help designers to determine which hull form aspect to adjust in case design requirements need them to do so. The information is obtained by firstly conducting a large series of CFD...doctoral thesis 2019

Maljaars, J.L. (author)Over the years, the installed capacity of offshore wind turbines is increasing rapidly. However, the Levelized Costs Of Energy (LCOE) is still higher than the LCOE of traditional energy production methods like nuclear power or energy from coals or gas. This research focuses on a further decrease of the LCOE, by minimizing the mass of a monopile...master thesis 2017

Yang, D. (author), Sileryte, R. (author), D'Aquilio, A. (author), Turrin, M. (author)Building performance simulations are usually timeconsuming. They may account for the major portion of time spent in Computational Design Optimization (CDO), for instance, annual hourly daylight and energy simulations. In this case, the optimization may become less efficient or even infeasible within a limited time frame of real-world projects,...conference paper 2016
