Vector Fields and Differential Forms on the Orbit Space of a Proper Action
Axioms, 2021 In this paper, we study differential forms and vector fields on the orbit space of a proper action of a Lie group on a smooth manifold, defining them as multilinear maps on the generators of infinitesimal diffeomorphisms, respectively.

The hot orbit: Orbital cellulitis
Middle East African Journal of Ophthalmology, 2012 Orbital cellulitis is an uncommon condition previously associated with severe complications. If untreated, orbital cellulitis can be potentially sight and life threatening. It can affect both adults and children but has a greater tendency to occur in the pediatric age group. The infection most commonly originates from sinuses, eyelids or face, retained

Robotic Manipulation and Capture in Space: A Survey
Frontiers in Robotics and AI, 2021 Space exploration and exploitation depend on the development of on-orbit robotic capabilities for tasks such as servicing of satellites, removing of orbital debris, or construction and maintenance of orbital assets. Manipulation and capture of objects on-

Haemangiopericytoma of the orbit [PDF]
Australian and New Zealand Journal of Ophthalmology, 1992 AbstractOrbital haemangiopericytomas are ideally managed by complete surgical excision in the first instance. This is frequently not achieved, because difficulty in making the diagnosis preoperatively results in incisional biopsy and the highly vascular nature of the tumour makes complete excision difficult.

Symposium - International Astronomical Union, 1987 Orbits that respect at least three isolating integrals of motion have very special structures in phase space. The main characteristics of this structure are reviewed, and the concrete examples that are provided by orbits in Stäckel potentials, are discussed.

Assessment of S-NPP VIIRS On-Orbit Radiometric Calibration and Performance
Remote Sensing, 2016 The VIIRS instrument on board the S-NPP spacecraft has successfully operated for more than four years since its launch in October 2011. Many VIIRS environmental data records (EDR) have been continuously generated from its sensor data records (SDR) with ...

Rarefied gas effects on the aerodynamics of high area-to-mass ratio spacecraft in orbit [PDF]
, 2013 The aerodynamic situation of a satellite-on-a-chip operating in low Earth orbit bears some resemblance to a classical Crookes radiometer. The large area-to-mass ratio characteristic of a SpaceChip means that very small surface-dependent forces produce ...
