Dual-loop integration framework for model-based system design and reliability analysis using Bayesian networks

Results in Engineering
Integrating model-based systems engineering (MBSE) and reliability analysis is challenging due to the lack of life-cycle reliability consideration in system design, difficulty in tracking design changes in reliability modeling, and limited quantitative ...

Correlation functions of small-scale fluctuations of the interplanetary magnetic field

, 2010
The Interplanetary Magnetic Field shows complex spatial and temporal variations. Single spacecraft measurements reveal only a one dimensional section of this rich four dimensional phenomenon.

In situ evidence for the structure of the magnetic null in a 3D reconnection event in the Earth's magnetotail [PDF]

, 2006
Magnetic reconnection is one of the most important processes in astrophysical, space and laboratory plasmas. Identifying the structure around the point at which the magnetic field lines break and subsequently reform, known as the magnetic null point, is ...

Single-event upsets in the Cluster and Double Star Digital Wave Processor instruments [PDF]

, 2013
Radiation-induced upsets are an important issue for electronic circuits operating in space. Upsets due to solar protons, trapped protons, and galactic cosmic rays are frequently observed.

The Cluster Magnetic Field Investigation: overview of in-flight performance and initial results [PDF]

Annales Geophysicae, 2001
The accurate measurement of the magnetic field along the orbits of the four Cluster spacecraft is a primary objective of the mission. The magnetic field is a key constituent of the plasma in and around the magnetosphere, and it plays an active role

ION INJECTION AT QUASI-PARALLEL SHOCKS SEEN BY THE CLUSTER SPACECRAFT

The Astrophysical Journal Letters, 2016
ABSTRACT Collisionless shocks in space plasma are known to be capable of accelerating ions to very high energies through diffusive shock acceleration (DSA). This process requires an injection of suprathermal ions, but the mechanisms producing such a suprathermal ion seed population are still not fully understood. We study acceleration of

Spacecraft potential control for Double Star [PDF]

Annales Geophysicae, 2005
The spacecraft potential of Double Star TC-1 is positive in large parts of the orbits due to the photo-effect from solar EUV irradiation. These positive potentials typically disturb low energy plasma measurements on board. The potential can be reduced,
