The majority of ankle prostheses available today are passive, lacking the net positive energy output of biological ankles, which tends to lead to asymmetric gait and related health issues. Recent advancements in powered prostheses tend to mimic ankle joint behavior, but design constraints like weight, size, and energy efficiency, along with challenges in performance evaluation and control development, remain significant.

The global shift towards carbon-neutral energy systems necessitates in-depth, forward-looking analysis and modelling, motivated by the scale and multifaceted nature of the transformations at hand. This thesis examines the coupling of macroeconomic models and energy system models to generate policy-relevant insights into the dynamics of the energy transition. Such integrative approach reveals new dynamics and trajectories that would remain hidden if each model were considered in isolation.

Given the environmental challenges related to the construction sector which is one of the most impacting sectors in terms of energy demand, CO2 emissions, natural resources consumption and waste production, a new class of circular waste-based materials for construction applications is developed. This new class of materials attempts to respond to the environmental challenges through their compositions, applications and environmental impacts, studied through an interdisciplinary research combining materials science, architecture and environment.

Wall-modeling in LES is of crucial importance to allow scale-resolving simulations of turbulent flows in industrial-scale devices. Numerous models were developed and validated for incompressible flows, including the simple quasi-analytical model based on Reichardt formula to approximate the ``law of the wall’’ (which covers the laminar sublayer, the transition region and the log layer). This work presents a new scaling of Reichardt formula to properly take into account strong compressibility effects in wall-modeled LES (wmLES).
