  1. 1. Study of hole mobility in amorphous polyethylene via kinetic Monte Carlo methods

    University essay from KTH/Matematik (Avd.)

    Author : Hannes Aspåker; [2022]
    Keywords : ;

    Abstract : This thesis presents a study of hole mobility in amorphous polyethylene using kinetic Monte Carlo (KMC) methods together with a novel chain segmentation model developed by Unge and Nilsson, which determines hole localization sites based on torsion angles along the polymer chain. An extension to the KMC algorithm was developed which improves performance by modelinground-trips between strongly interconnected localization sites. READ MORE

  3. 2. Approximation of General Semi-Markov Models Using Expolynomials

    University essay from KTH/Matematisk statistik

    Author : Niklas Nyholm; [2021]
    Keywords : applied mathematics; Markov modelling; Semi-Markov process; approximation theory; expolynomial; phase-type distribution; reliability analysis; tillämpad matematik; Markov modellering; Semi-Markov process; approximations teori; expolynom; phase-type fördelning; riskanalys;

    Abstract : Safety analysis is critical when developing new engineering systems. Many systems have to function under randomly occurring events, making stochastic processes useful in a safety modelling context. However, a general stochastic process is very challenging to analyse mathematically. READ MORE

  4. 3. A parameter study when drilling holes in flanges

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Endi Kobaslic; [2017]
    Keywords : Cutting parameters; Deflection; Intetnal turning; Stability; Vibrations; Invändig svarvning; Skärdata; Stabilitet; Utböjning; Vibrationer;

    Abstract : Stabilitet och vibrationer inom invändiga svarvningsprocesser är ett område som kräver mer forskning. Tidigare studier visar att problem med stabilitet och utböjning är vanligt vid dessa processer och att de orsakar oönskade vibrationer i processen. READ MORE

  5. 4. Numerical Solution to a Nonlinear External Ballistics Model for a Direct Fire Control System

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Skande; [2014]
    Keywords : ;

    Abstract : Detta examensarbete är en utvecklings- och evalueringsprocess av en numeriskt löst ytterballistik modell för ett eldledningssystem utvecklat av SAAB Technologies. Den befintliga ballistik modell som används av eldledningssystemet idag är linjäriserad vilket simplifierar problemet att nå upp till de hårda realtidskrav som finns, dock på grund av de approximationer och simplifieringar knutna till linjäriseringen finns det utrymme för förbättringar i termer av beräkningsnoggrannhet.

  6. 5. FX BASKET OPTIONS - Approximation and Smile Prices

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Patrik Karlsson; [2009]
    Keywords : hedging; FX; Black-Scholes; Volatility Smile.; Basket Option; Derivative; Local Volatility; Economics; econometrics; economic theory; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik; Business and Economics;

    Abstract : Pricing a Basket option for Foreign Exchange (FX) both with Monte Carlo (MC) techniques and built on different approximation techniques matching the moments of the Basket option. The thesis is built on the assumption that each underlying FX spot can be represented by a geometric Brownian motion (GBM) and thus have log normally distributed FX returns. READ MORE
