Research papers
- arXiv 2016 · arXiv preprint The mixed-phase version of moist-air entropy The aim of this note is to derive the mixed-phase version of the moist-air entropy potential temperature $θ_s$ derived in Marquet (2011).
- arXiv 2014 · arXiv preprint On the computation of moist-air specific thermal enthalpy The specific thermal enthalpy of a moist-air parcel is defined analytically following a method in which specific moist entropy is derived from the Third Law of thermodynamics.
- arXiv 2019 · arXiv preprint Application of the second law to the atmosphere: impacts of the third-law definition for the moist-air entropy Calculations of entropy fluxes and production rate have been evaluated with some success to study atmospheric processes. However, recurring questions arise as to how best to take into account entropy …
- arXiv 2026 · arXiv preprint Behaviour-aware Hybrid Architecture for Trust-driven Transmissions Reliable and secure communication is essential for mission-critical aerospace and defence operations involving autonomous platforms such as Unmanned Aerial Vehicles (UAVs), satellites, and ground cont…
- arXiv 2026 · arXiv preprint Geometric Inverse Flight Dynamics on SO(3) and Application to Tethered Fixed-Wing Aircraft We present a robotics-oriented, coordinate-free formulation of inverse flight dynamics for fixed-wing aircraft on SO(3). Translational force balance is written in the world frame and rotational dynami…
- Semantic Scholar 2024 · Article (The Journal of Nutrition, Health & Aging) The role of nutritional supplement on post-stroke fatigue: a pilot randomized controlled trial Objectives Post-stroke fatigue (PSF) is an experience characterized by an early feeling of exhaustion with fatigue, a lack of energy, and difficulty in exertion, both motor and cognitive.
