Thrust sheet evolution in the Kinlochewe region of the Moine Thrust Zone, N.W. Scotland and the Pelvoux-Brianconnais, French Alps [PDF]

open access: yes, 1984
Balanced and restored cross sections demonstrate a minimum 16 km shortening below the Moine Thrust and minimum restored wi1ths of 17 km between the La Meije and Combeynot Thrusts (external Alps), and 54 km between the frontal Subbrianconnais Thrust ...

Deformation and fluid processes in thrust sheets from the central Pyrenees [PDF]

open access: yes, 1989
Deformation and fluid processes in thrust sheets are studied using a small thrust system n the footwall of the Gavarnle Thrust, central Pyrenees. This system comprises a set of blind thrusts that Imbricate a thin Mesozoic cover succession (Triassic red ...

Displaced geostationary orbits using hybrid low-thrust propulsion [PDF]

open access: yes, 2012
In this paper, displaced geostationary orbits using hybrid low-thrust propulsion, a complementary combination of Solar Electric Propulsion (SEP) and solar sailing, are investigated to increase the capacity of the geostationary ring that is starting to ...

Design of optimal Earth pole-sitter transfers using low thrust propulsion [PDF]

open access: yes, 2011
Recent studies have shown the feasibility of an Earth pole-sitter mission using low-thrust propulsion. This mission concept involves a spacecraft following the Earth's polar axis to have a continuous, hemispherical view of one of the Earth's poles.

Studies on thrust characteristics of high‐thrust spiral motor

open access: yesElectrical Engineering in Japan, 2009
AbstractLinear actuators are used in various industrial applications. Conventional linear actuators are a combination of a rotational motor and a ball screw, a hydraulic actuator, or a linear motor. However, these actuators have some demerits. This paper proposes a spiral motor (SPRM) that comprises a helical stator and a helical mover.

Multiplicity with a thrust cut [PDF]

open access: yesZeitschrift f�r Physik C Particles and Fields, 1994
We evaluate the multiplicity of hadrons in the $e^+e^-$-annihilation at a given thrust $T$ in the modified leading-log approximation, including $O(\sqrt{α_s})$ corrections. The calculation is done at a large value of $τ=1-T$ by the use of the factorisation which takes place in the one-particle-inclusive cross section at a given $τ$.
