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

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

    Författare :Yani di Giovanni; [2019]
    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.

    Sammanfattning : Textual data is one of the most widespread forms of data and the amount of such data available in the world increases at a rapid rate. Text can be understood as either a sequence of characters or words, where the latter approach is the most common. LÄS MER

  5. 5. Crowd evacuation in high-density scenarios

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Ines Cilenti; [2019]
    Nyckelord :Crowd evacuation; high-density; crowd pressure; video analysis; bottleneck; outdoor event; local density.; Technology and Engineering;

    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
