Negative Linear Compressibility
Negative linear compressibility (NLC) describes the relative increase or decrease in a material's linear dimension when subjected to an increase or decrease in external pressure, or a decrease or increase in internal pressure, respectively. This is a rare material property found

A secure control framework for self-triggered control
Exploiting aperiodic sampling for the detection and prevention of stealthy attacks
Watermarking
Stc
This thesis addresses the detection and prevention of adversarial attacks on self-triggered control (STC) systems and demonstrates how manipulating the sampling times can be used to provide a secure control framework. Secure control is vital to guarantee both the safety and secur

Feature Engineering for Low-Thrust Trajectory Optimization
A Systematic Analysis Using Pontryagin Fuel-Optimal Earth-Mars Transfer Trajectories
Using low-thrust propulsion for interplanetary space missions has the potential to allow for more payload for the same mass put into orbit compared to what impulsive propulsion would allow for. The disadvantages are found in mission planning, however, as the continuous nature of
