  1. 1. Analysis and Implementation of an Age Structured Model of the Cell Cycle

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Anna Broms; [2017]
    Nyckelord :age structured model; cell cycle; cell population dynamics; nonlinear integral equations; Romberg s method; Mathematics and Statistics;

    Sammanfattning : In an age-structured model originating from cancer research, the cell cycle is divided into two phases: Phase 1 of variable length, consisting of the biologically so called G1 phase, and Phase 2 of fixed length, consisting of the so called S, G2 and M phases. A system of nonlinear PDEs along with initial and boundary data describes the number densities of cells in the two phases, depending on time and age (where age is the time spent in a phase). LÄS MER

  3. 2. Numerical simulation of an inertial spheroidal particle in Stokes flow

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Joar Bagge; [2015]
    Nyckelord :Fluid mechanics; Stokes flow; rigid body dynamics; spheroidal particles; inertia; integral equations; boundary integrals; double layer potentials; quadrature by expansion; Jeffery orbits; linear shear flow; quadratic flow; paraboloidal flow; Strömningsmekanik; Stokesflöde; stelkroppsdynamik; sfäroidiska partiklar; tröghet; integralekvationer; randintegraler; dubbellagerpotentialer; quadrature by expansion; Jeffery-banor; linjärt skjuvflöde; kvadratiskt flöde; paraboloidiskt flöde;

    Sammanfattning : Particle suspensions occur in many situations in nature and industry. In this master’s thesis, the motion of a single rigid spheroidal particle immersed in Stokes flow is studied numerically using a boundary integral method and a new specialized quadrature method known as quadrature by expansion (QBX).

  4. 3. On long-range and high frequency propagation alongparallel strip conductors in layered media : A simplified yet accurate method using the mode matching technique in the spectral domain

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektroteknisk teori och konstruktion

    Författare :Benjamin Oakes; [2013]
    Nyckelord :;

    Sammanfattning : Electrical arcing in the railway environment radiates wideband noise that can disturb nearbysensitive electronics e.g. signaling systems. High frequency disturbances follow conducting wiresand rails. LÄS MER

  5. 4. Integralekvationer

    Magister-uppsats, Institutionen för ingenjörsvetenskap, fysik och matematik

    Författare :Fredrik Smeds; [2005]
    Nyckelord :Integralekvationer; Ivar Fredholm;

    Sammanfattning : Denna skrift är huvudsakligen en översättning av delar av kompendiet Integral Equations av Yury V. Shestopalov och Yury G. Smirnov (Karlstads universitet 2002), till vilken jag bifogat några egna exempel och en biografi över Ivar Fredholm. LÄS MER
