Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab
Symbolic Interaction, EarlyView.How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

A Dual-Prediction Framework for High-Energy Proton Flux Driven by Graph Neural Networks
IEEE AccessPredicting high-energy proton flux is essential for radiation-effect protection of satellite devices. We introduce a dual-prediction framework based on Graph Neural Networks (GNN) to model proton flux from both non-time-series and time-series ...

Nonlinear Tracking Control of Rigid Spacecraft under Disturbance using PID-type H-infinity Adaptive State Feedback [PDF]
, 2015 Future space programs will require an agile relative position and attitude control technology for spacecraft. Rendezvous and docking, capture of inoperative spacecraft and formation flight in orbit are the typical scenarios.

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review
Systems Engineering, EarlyView.ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

Numerical Study of the Thermal Model on High Uniformity Temperature Test Platform
MATEC Web of Conferences, 2019 The surface temperature uniformity of a test platform with an effective test area of 600 mm × 600 mm was numerically studied. The conductive heat transfer model for the test platform and the device under test (DUT) installed on the surface was ...

Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack
Systems Engineering, EarlyView.ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...
