  2. 1. Entrepreneurial Methods

    Author : Yashar Mansoori; Chalmers University of Technology; []
    Keywords : entrepreneurial methods; theory and practice; learning; uncertainty; method perspective;

    Abstract : The interest in approaches for creating new ventures has been amplified by a recent surge in practitioner-driven entrepreneurial methods. Entrepreneurship education programs in prestigious institutions as well as prominent incubators and accelerators have started adopting these methods. READ MORE

  4. 2. Active Control of Propeller-Induced Noise in Aircraft : Algorithms & Methods

    Author : Sven Johansson; []

    Abstract : In the last decade acoustic noise has become more and more regarded as a problem. In cars, boats, trains and aircraft, low-frequency noise reduces comfort. Lightweight materials and more powerful engines are used in high-speed vehicles, resulting in a general increase in interior noise levels. READ MORE

  6. 4. Numerical Methods for Wave Propagation : Analysis and Applications in Quantum Dynamics

    Author : Emil Kieri; Sverker Holmgren; Vasile Gradinaru; Hans O. Karlsson; Tobias Jahnke; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; computational wave propagation; quantum dynamics; time-dependent Schrödinger equation; spectral methods; Gaussian beams; splitting methods; low-rank approximation; Scientific Computing; Beräkningsvetenskap;

    Abstract : We study numerical methods for time-dependent partial differential equations describing wave propagation, primarily applied to problems in quantum dynamics governed by the time-dependent Schrödinger equation (TDSE). We consider both methods for spatial approximation and for time stepping. READ MORE
