  1. 1. B-spline Parametrized Approximation and Variation of Vehicle Trajectories For Autonomous Vehicles Simulation

    University essay from KTH/Matematik (Avd.)

    Author : Karolina Siemieniuk; [2021]
    Keywords : ;

    Abstract : A big focus of the Automotive Industry’s work is now on the development ofAutonomous Vehicles (AVs). In order to be able to release them on the market,they need to be tested and validated in a safe and efficient way. That is whycompanies working on the development of AVs use simulation to test the workthey are completing. READ MORE

  3. 2. Parameter selection and derivative conditions for B-splines applied to gas turbine blade modeling

    University essay from Lunds universitet/Matematik LTH

    Author : Andreas Söderlund; [2015]
    Keywords : B-splines; spline interpolation; parameter selection; knot selection; Bezier curves; NURBS; derivative conditions; geometric continuity; turbine blade; turbine; compressor; compressor blade; interpolation; Mathematics and Statistics;

    Abstract : In gas turbine blade modeling a stable but yet flexible method of describing the blade shape is crucial. Polynomials and B ́ezier curves have previously been used and in this paper B-splines are employed instead. READ MORE

  4. 3. Numerical Solution of a Nonlinear Inverse Heat Conduction Problem

    University essay from Matematiska institutionen; Linköpings universitet

    Author : Muhammad Anwar Hussain; [2010]
    Keywords : inverse problem; ill-posed; Cauchy problem; heat conduction; well-posed; nonlinear problem; spline derivative; spectral method.;

    Abstract :  The inverse heat conduction problem also frequently referred as the sideways heat equation, in short SHE, is considered as a mathematical model for a real application, where it is desirable for someone to determine the temperature on the surface of a body. Since the surface itself is inaccessible for measurements, one is restricted to use temperature data from the interior measurements. READ MORE

  5. 4. Methods for Residual Generation Using Mixed Causality in Model Based Diagnosis

    University essay from Institutionen för systemteknik

    Author : Magnus Johansson; Johan Kingstedt; [2008]
    Keywords : model based residual generation; derivative estimation; structural methods;

    Abstract : Several different air pollutions are produced during combustion in a diesel engine, for example nitric oxides, NOx, which can be harmful for humans. This has led to stricter emission legislations for heavy duty trucks. The law requires both lower emissions and an On-Board Diagnosis system for all manufactured heavy duty trucks. READ MORE
