  1. 11. The Hanging Rope: A Convex Optimization Problem in the Calculus of Variations

    University essay from Lunds universitet/Matematik LTH

    Author : Erik Steen; [2020]
    Keywords : Elasticity theory; non-linear materials; calculus of variation; convex analysis; Legendre transform; Mathematics and Statistics;

    Abstract : We study the problem first introduced by Verma and Keller in 1984 of how to taper a heavy rope such that its elongation is minimized. The problem is stated as an optimization problem of a functional J[w]. Specifically we provide a proof of optimality for the solution using traditional convex optimization techniques. READ MORE

    Keywords : häst; anestesi; uppvakning; assisterad uppvakning; assisterad resning; stress;

    Abstract : Hästars uppvakning efter anestesi innebär många risker. Detta bidrar till att mortaliteten vid hästanestesi är mycket högre jämfört med mortaliteten vid anestesi av smådjur och människor. Hästars naturliga flyktbeteende gör ofta att de försöker resa sig innan narkosläkemedlen eliminerats. READ MORE
