"We report extensive numerical simulations of the flow of anisotropic self-propelled particles through a constriction. In particular, we explore the role of the particles’ desired orientation with respect to the moving...

Abstract Control of frontal plane mechanics requires active integration of sensory feedback to regulate stability in response to gait perturbations, such as split‐belt walking (SBW). In comparison to sagittal plane mec...

Abstract. During each voyage, the vessel's traction capacity decreases due to the gradual degradation of the characteristics of the propulsion complex. This process is influenced by factors such as fouling of the vessel'...

A conceptual and feasibility study of an RBCC SSTO catapult-launched reusable strap-on parallel-boosted gliding-reentry lifting-body spaceplane for economic manned short-duration 300-kg payload LEO access is presented an...

One of the main figures of merit in laser-ablative propulsion is the specific impulse, Isp, defined as the impulse per unit weight of fuel, and it is related to the exhaust velocity, ve, by the acceleration of gravity, I...

AUVs have essential applications in oceanic investigations, environmental characterization, and subsea surveys where accuracy in positioning and stability for navigation is challenging. AUV proposed in the present work a...

Excessive armature mass fraction in asynchronous induction coil thrusters critically constrains payload capacity and propulsion efficiency. This study addresses this limitation through two lightweight strategies: axial h...

In this paper it is presented the concept and design of a new type of spacecraft that could be used to make the first manned interstellar travel. Solar one would integrate three near-term technologies, namely: compact nu...

"Orbital maneuvering of microsatellite and nanosatellite requirements can be efficiently addressed by planar nozzles, in which realtime thrust control is gained actuating on the nozzle throat area. In the present work, t...
