1. 1. Space Situational Awareness with the Swedish Allsky Meteor Network

   Master-uppsats, Uppsala universitet/Observationell astrofysik

   Författare :Simon Alinder; [2019]
   Nyckelord :SSA; space situational awareness; IOD; initial orbit determination; orbit determination; satellite identification; all-sky; rymdlägessituation; SSA; omloppsbana; banbestämning;

   Sammanfattning : This thesis investigates the use of the Swedish Allsky Meteor Network (SAMN) for observing, identifying, and determining the orbits of satellites. The overall goal of this project is to determine the feasibility of using such a network for Space Situational Awareness (SSA) purposes, which requires identification and monitoring of objects in orbit.

3. 2. Numerical experiments with FEMLAB® to support mathematical research

   Uppsats för yrkesexamina på grundnivå, Matematiska institutionen

   Författare :Mattias Hansson; [2005]
   Nyckelord :FEMLAB; numerical experiments; Dirichlet problems for the Infinity-Laplace equation; AMLE; Absolutely Minimizing Lipschitz Extension; sets of uniqueness; critical segments; lines of singularity;

   Sammanfattning : Using the finite element software FEMLAB® solutions are computed to Dirichlet problems for the Infinity-Laplace equation ∆∞(u) ≡ u2xuxx + 2uxuyuxy + u2yuyy = 0. For numerical reasons ∆q(u) = div (|▼u|q▼u) = 0, which (formally) approaches as ∆∞(u) = 0 as q → ∞, is used in computation. LÄS MER
