On-Orbit Magnetometer Data Calibration Using Genetic Algorithm and Interchangeability of the Calibration Parameters

open access: yesApplied Sciences, 2023
Magnetometers are important sensors with applications in the attitude determination and control systems of satellites. CubeSats have certain limitations related to power, mass, and volume.

Cyclic Orbit Codes [PDF]

open access: yes, 2011
In network coding a constant dimension code consists of a set of k-dimensional subspaces of F_q^n. Orbit codes are constant dimension codes which are defined as orbits of a subgroup of the general linear group, acting on the set of all subspaces of F_q^n.

Orbits [PDF]

open access: yesSymposium - 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

open access: yesGMS 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.

Extension of the sun-synchronous Orbit [PDF]

open access: yes, 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.

Orbital Rhabdomyosarcoma [PDF]

open access: yesCancer Control, 2004
Although rhabdomyosarcoma (RMS) is a rare tumor among the entire group of mesenchymal malignancies, it is a relatively common lesion and significant challenge for the ocular oncologist in terms of its diagnosis and management.A comprehensive literature search of articles published over the past 30 years in PubMed was conducted.Orbital RMS usually ...

The hot orbit: Orbital cellulitis

open access: yesMiddle 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

Rescue of the MERTK phagocytic defect in a human iPSC disease model using translational read-through inducing drugs

open access: yesScientific Reports, 2017
Inherited retinal dystrophies are an important cause of blindness, for which currently there are no effective treatments. In order to study this heterogeneous group of diseases, adequate disease models are required in order to better understand pathology

Thermal Bending of the Rotor Due to Rotor-to-Stator Rub

open access: yesInternational 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 ...

Performance Evaluation of Machine Learning Methods for Anomaly Detection in CubeSat Solar Panels

open access: yesApplied 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.
