3. ## 3. An introduction to some ordinary differential equations governing stellar structures

Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten)

Nyckelord :Mathematics and Statistics;

Sammanfattning : The Lane-Emden equation is a non-linear differential equation governing the equilibrium of polytropic stationary self-gravitating, spherically symmetric star models; $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\theta }{d\xi }}}\right)+\theta ^{n}=0.$$ In the isothermal cases we have the Chandrasekhar equation: $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\psi}{d\xi }}}\right)-e^{-\psi}=0$$ After having derived these models, we will go through all cases for which analytic solutions are achievable.

5. ## 5. Crowd evacuation in high-density scenarios

Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

Sammanfattning : Nowadays, is becoming increasingly frequent holding events in outdoor environments, involving a large number of people, even though these spaces were not designed from a safe prospective, in the way that safety is defined today. In such events, high density conditions is an ongoing issue, as the evacuation becomes very complex, due to the space design and the interaction among the pedestrians. LÄS MER
