First simultaneous observations of flux transfer events at the high-latitude magnetopause by the Cluster spacecraft and pulsed radar signatures in the conjugate ionosphere by the CUTLASS and EISCAT radars

open access: yes, 2001
. Cluster magnetic field data are studied during an outbound pass through the post-noon high-latitude magnetopause region on 14 February 2001. The onset of several minute perturbations in the magnetospheric field was observed in conjunction with a ...

Hierarchical Planning Applied to the Preliminary Design of CubeSats: Nanospace Study

open access: yesSystems Engineering, EarlyView.
ABSTRACT CubeSat design has been already studied and formalized but knowledge representation remains a challenge. The management of human‐learnt knowledge during the process is not an aspect that is often spoken about. This paper discusses the proposal of integrating a hierarchical planning approach with a model‐based one to the open‐source Nanospace ...

Canonical Electromagnetic Observables for Systematic Characterization of Electric and Magnetic Wave Field Data on board Spacecraft [PDF]

open access: yesarXiv, 2008
We present a new characterization of partially coherent electric and magnetic wave vector fields.This characterization is based on the 36 auto/cross correlations of the 3+3 complex Cartesian components of the electric and magnetic wave fields and is particularly suited for analyzing electromagnetic wave data on board spacecraft.

Exploring South Korean Foreign Direct Investment Motives and State‐Level Location Decisions: US Evidence 1995–2008

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT This study uses a novel application of panel fuzzy‐set qualitative comparative analysis (fsQCA) in the international management field. utilizing a unique database capturing reasons for foreign direct investment (FDI), and state‐level location, we explain location decisions of high‐technology South Korean (henceforth Korean) multinational ...

Small-scale dipolarization fronts in the Earth′s magnetotail

open access: yesEarth and Planetary Physics, 2019
Previous studies suggest that dipolarization fronts (DFs) are 1 to 3RE (RE is the earth radius) wide in the dawn-dusk direction. Recent kinetic simulations have found that DFs may break up into small-scale structures after they are produced by ...

Transition from substorm growth to substorm expansion phase as observed with a radial configuration of ISTP and Cluster spacecraft

open access: yes, 2005
Transition from the growth phase to the substorm expansion during a well-isolated substorm with a strong growth phase is investigated using a unique radial (THEMIS- like) spacecraft constellation near midnight, including the probing of the tail current ...

Review of asteroid, meteor, and meteorite‐type links

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.
