RF Helicon-based Plasma Thruster (IPT): Design, Set-up, and First Ignition
(International Astronautical Federation, 2019)
Conference report
Restricted access - publisher's policyTo extend missions lifetime at very low altitudes, an efficient propulsion system is requiredto compensate for aerodynamic drag. One solution is Atmosphere-Breathing Electric Propulsion (ABEP). It collects atmospheric ... -
Ground-based experimental facility for orbital aerodynamics research: design, construction and characterisation
(International Astronautical Federation, 2020)
Conference lecture
Restricted access - publisher's policyIn very low Earth orbits (VLEO), below 450 km altitude, the aerodynamic properties of satellites are primarily determined by the flow regime, free molecular flow, and the interaction of atomic oxygen with the surfacesof ... -

(International Astronautical Federation, 2020)
Conference lecture
Restricted access - publisher's policyThe DISCOVERER project is developing technologies to enable commercially-viablesustained-operation of satellites in very low Earth orbitsfor communications and remote sensing applications. Operatingcloser to the surface ... -
Investigation of Novel Drag-Reducing and Atomic Oxygen Resistant Materials in Very Low Earth Orbit using SOAR (Satellite for Orbital Aerodynamics Research)
(International Astronautical Federation, 2020)
Conference report
Restricted access - publisher's policyInterest in operating spacecraft in very low Earth orbits (VLEO), those below approximately 450 km, is growing due to the numerous benefits offered by reducing altitude. For remote sensing and Earth observation applications, ... -
Commissioning of a beam screen test bench experiment with a future circular hadron collider type synchrotron radiation beam
(American Physical Society (APS), 2019-08-23)
Article
Open AccessCoping with synchrotron radiation (SR) that originated at superconducting bending magnets is one of the major challenges in the design of the vacuum beam pipes of hadron colliders. In the case of the Future Circular hadron ... -
Transposition of the mechanical behavior from model to prototype of Francis turbines
(Elsevier, 2020-06-01)
Article
Restricted access - publisher's policyHydropower is nowadays essential for balancing the electrical grid providing flexibility and fast response. The role of hydraulic turbines has changed from working at their Best Efficiency Point (BEP) to work in the whole ... -

Article
Open AccessAdditive manufacturing (AM) processes have undergone significant progress in recent years, having been implemented in sectors as diverse as automotive, aerospace, electrical component manufacturing, etc. In the medical ... -
Optimal postponement in supply chain network design under uncertainty: an application for additive manufacturing
(Taylor & Francis, 2020-06-17)
Article
Open AccessThis study presents a new two-stage stochastic programming decision model for assessing how to introduce some new manufacturing technology into any generic supply and distribution chain. It additionally determines the ... -
Surface damaging of brass and steel pins when sliding over nitrided samples cut by finishing and roughing EDM conditions
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-07-17)
Article
Open AccessIn the forging industry, surface quality and surface treatments of dies are crucial parameters to extend their life. These components are usually machined by milling or by Electrical Discharge Machining (EDM), and the final ... -
Fatigue behavior of PLA-wood composite manufactured by fused filament fabrication
(Elsevier, 2020-07-08)
Article
Open AccessIn this paper, the fatigue behavior of a polylactic acid-based composite reinforced with wood (trademarked as Timberfill) processed through fused filament fabrication is analyzed through rotating bending fatigue tests. ... -
Topology optimization of thermal problems in a nonsmooth variational setting: closed-form optimality criteria
(Springer, 2020-06)
Article
Restricted access - publisher's policyThis paper extends the nonsmooth Relaxed Variational Approach (RVA) to topology optimization, proposed by the authors in a preceding work, to the solution of thermal optimization problems. First, the RVA topology optimization ... -
