Contingency Management Concept Generation for U-Space System

open access: yes2022 Integrated Communication, Navigation and Surveillance Conference (ICNS), 2022
Contingency management in aviation is a vital concept that ensures safety, security, and efficiency in operations. To fully benefit from the envisioned Advanced Air Mobility system, the need of a structured and system-wide contingency planning will be even more important since the air transportation system paradigm will shift into a highly automated ...

Index boundedness and uniform connectedness of space of the G-permutation degree

open access: yesApplied General Topology, 2021
In this paper the properties of space of the G-permutation degree, like: weight, uniform connectedness and index boundedness are studied. It is proved that: (1) If (X, U) is a uniform space, then the mapping π s n, G : (X n , U n ) → (SP n GX, SP n GU ...

Slow solar wind acceleration through the middle corona: Spacecraft radio studies

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The “Middle Corona”, defined by recent consensus as the region spanning 1.5–6 solar radii (R⊙, heliocentric), is an important zone through which several structural and dynamic changes occur in coronal streamer regions. Among these is a regime change from

Dimension of special μ-spaces [PDF]

open access: yes, 1980
K. Nagami in [5] called a space X a u-space if X is embedded in the countable product of paracompact σ-metric spaces. Especially he called X a cubic u-space if X is the conutable product itself of paracompact ..

Resampling images in Fourier domain [PDF]

open access: yes, 2014
When simulating sky images, one often takes a galaxy image $F(x)$ defined by a set of pixelized samples and an interpolation kernel, and then wants to produce a new sampled image representing this galaxy as it would appear with a different point-spread ...

Priority-Aware Conflict Resolution for U-Space

open access: yesElectronics, 2022
In the context of the future urban mobility airspaces, U-space lays the foundation for unmanned aircrafts to be integrated with conventionally manned traffic to offer a multitude of services to citizens and businesses, such as urban public transport, goods movement, parcel delivery, etc.

The Optical Signature of a Bottom Boundary Layer Ventilation Event in the Northern Gulf of Mexico's Hypoxic Zone

open access: yesGeophysical Research Letters, 2018
Oceanographic observations in the northern Gulf of Mexico captured an unusual combination of atmospheric forcing and shelf frontal dynamics that brought about the surface ventilation of sediment‐laden bottom waters.

Design of Active PWM Control Driver Circuit for Torquer System Using CCII

open access: yesIEEE Access, 2021
This research examines a torquer system for satellite attitude control which requires low energy, or average power, to control its moment. The magnetic torquer consists of an LR component, source and switching pulse.
