Extension of the sun-synchronous Orbit [PDF]
, 2010 Through careful consideration of the orbit perturbation force due to the oblate nature of the primary body a secular variation of the ascending node angle of a near-polar orbit can be induced without expulsion of propellant.

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.

Orbito-sinal foreign body with floor fracture: an unusual presentation
GMS Ophthalmology Cases, 2020 Wooden foreign bodies penetrating through the orbit into paranasal sinuses are rare. We report a case of a young male who complained of double vision, pain and redness after a fall from a tree. There was no external wound over periocular skin.

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

Performance Evaluation of Machine Learning Methods for Anomaly Detection in CubeSat Solar Panels
Applied Sciences, 2022 CubeSat requirements in terms of size, weight, and power restrict the possibility of having redundant systems. Consequently, telemetry data are the primary way to verify the status of the satellites in operation.

Nature Communications, 2019 AbstractMillimeter-sized objects trapped at a liquid surface distort the interface by their weight, which in turn attracts them towards each other. This ubiquitous phenomenon, colloquially called the “Cheerios effect” is seen in the clumping of cereals in a breakfast bowl, and turns out to be a highly promising route towards controlled self-assembly of

Realization of two-dimensional spin-orbit coupling for Bose-Einstein condensates [PDF]
Science, 2015 Spin-orbit coupling in an optical lattice Studying topological matter in cold-atom systems may bring fresh insights, thanks to the intrinsic purity and controllability of this experimental setting. However, the necessary spin-orbit coupling can be tricky

Thermal Bending of the Rotor Due to Rotor-to-Stator Rub
International Journal of Rotating Machinery, 2000 The rotor thermal bending due to the rotor-to-stator rubbing can lead to one of three types of observed rotor lateral motion: (1) spiral with increasing amplitude, (2) oscillating between rub]no-rub conditions, and (3) asymptotical approach to the rotor ...
