All The Stars We Cannot See: A deep look into real-time satellite traffic

A fresh look into pulsating PG1159 stars

To improve the understanding of the pulsational instabilities of some of the PG1159-type pre-white dwarfs we performed detailed stability analyses on helium star evolutionary models. With the canonical chemical compositions, pulsational instabilities were encountered for all stellar masses considered (0.57, 0.63, 0.7 M⊙). The blue boundary agrees satisfactorily with observations. The red edge, ...

We see only what we look for: imaging cardiac inflammation.

Coordinated look-ahead scheduling for real-time traffic signal control

We take an agent-based approach to real-time traffic signal control based on coordinated look-ahead scheduling. At each decision point, each agent constructs a schedule that optimizes movement of the currently approaching traffic through its intersection. For strengthening its local view, each agent queries the scheduled outflows from its direct upstream neighbors to obtain an optimistic observ...

A further look into the pulsating PG1159 stars

To improve our understanding of the pulsational instabilities found in some of the PG1159-type pre-white dwarfs we performed detailed nonradial stability analyses on heliumstar evolutionary models. Adopting canonical chemical compositions as derived from spectroscopic observations, we found pulsational instabilities for all stellar masses considered (0.57, 0.63, 0.7 M ). The blue boundary of th...
