Evaluation of daylighting strategies based on their embodied carbon emissions: a first methodological framework and case study

Marilyne Andersen, Nazanin Rezaei Oghazi, Thomas Bernard Paul Jusselme

The impact of daylighting strategies on a building’s carbon emissions have so far been assessed mostly based on the building’s use phase and their resulting operational benefits, overlooking embodied carbon emissions of material production, construction, m ...

H∞ and μ-Synthesis for Nanosatellites Rendezvous and Docking

Volker Gass, Camille Sébastien Pirat

In this brief, the nanosatellite rendezvous and docking problem is tackled. It was never attempted for small spacecraft, as critical technologies, such as six-degree-of-freedom (DoF) micropropulsion systems, have only recently become available due to advan ...

Charge Neutralization and Direct Thrust Measurements from Bipolar Pairs of Ionic- Electrospray Thrusters

Herbert Shea, Daniel George Courtney

lectrospray (ES) thrusters are unique in their ability to emit both positive and negative beams, each contributing similarly to thrust. Spacecraft charging could be prevented without a dedicated neutralizer if currents of simultaneously emitted opposing po ...

Realization of a Diamagnetically Levitating Rotor Driven by Electrostatic Field

Hannes Bleuler, Yuanping Xu, Qingwen Cui, Ryosuke Kan, Jin Zhou

In this paper, a novel configuration of frictionless diamagnetic levitation combined with electrostatic glass motor is presented. A 12.5 mm diameter disc shaped rotor comprised of pyrolytic graphite and glass is fabricated. The rotor disc is levitated stab ...

Dual Langmuir-probe array for 3D plasma studies in TORPEX

Ambrogio Fasoli, Ivo Furno, Fabio Avino, Rémy Jacquier, Marcelo Baquero Ruiz, Oulfa Chellaï, Fabian Manke

We have designed and installed a new Langmuir-probe (LP) array diagnostic to determine basic three-dimensional (3D) features of plasmas in TORPEX. The diagnostic consists of two identical LP arrays, placed on opposite sides of the apparatus, which provide ...

Influences of porous reservoir Laplace pressure on emissions from passively fed ionic liquid electrospray sources

Herbert Shea, Daniel George Courtney

Passively fed ionic liquid electrospray sources are capable of efficiently emitting a variety of ion beams with promising applications to spacecraft propulsion and as focused ion beams. Practical devices will require integrated or coupled ionic liquid rese ...

A Methodology for Profiling and Partitioning Stream Programs on Many-core Architectures

Marco Mattavelli, Malgorzata Maria Michalska, Jani Boutellier

Maximizing the data throughput is a very common implementation objective for several streaming applications. Such task is particularly challenging for implementations based on many-core and multi-core target platforms because, in general, it implies tackli ...

FEASIBILITY STUDY OF GNSS AS NAVIGATION SYSTEM TO REACH THE MOON

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano

Reaching the Moon poses very strict requirements in terms of performance, flexibility and cost for all the spacecraft subsystems. These requirements become more stringent if the mission is designed to be accomplished using a small spacecraft. The navigatio ...
