  1. 6. Acoustical properties of earplugs

    Författare :Per Hiselius; Teknisk akustik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; acoustic modelling; objective measurement; insertion loss; earplugs; HPE; HPD; hearing protectors; Two-Port; Four-Pole; attenuation; electro acoustics; acoustics;

    Sammanfattning : In this study an experimental setup for measurements of high impedance objects in ducts, yielding the acoustical Two-Port properties of the object, is applied to earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent on duplicating the human ear. LÄS MER

  3. 7. Limited and universal salvation : A text-oriented and hermeneutical study of two perspectives in Paul

    Författare :Sven Hillert; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Religion; Bible; New Testament; Paul; universal salvation; limited salvation; perspectives; function; argumentation; multidimensionality; liberation theology; Religionsvetenskap Teologi; Religion Theology; Religionsvetenskap Teologi; New Testament Exegesis; nya testamentets exegetik;

    Sammanfattning : The purpose of this dissertation is to determine whether the letters of Paul can be said to support or to refute a modern belief in universal salvation. Theoretically many scholars would regard views of limited and universal salvation as mutually exclusive. LÄS MER

  4. 8. Ömse sidor om vägen : Allén och landskapet i Skåne 1700-1900

    Författare :Patrik Olsson; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Avenue; tree-lined road; landscape; aesthetics; historical geography; Scania.;

    Sammanfattning : This thesis is about avenues (tree-lined roads – in Swedish alléer). Avenues are a characteristic landscape element in many parts of Scania. This is an object created by man with a clear visual effect in the landscape. The avenue is also something which is both nature and culture, a man-made object from nature. LÄS MER

  5. 9. Methods for Reducing the Complexity of Geometrical Structures Based on CFD Programming : Time Efficient Simulations Based on Volume Forces Coupled with Single and Two-phase Flow

    Författare :Kamal Rezk; Lars Nilsson; Jonas Berghel; Erik Dahlquist; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical design cycle; CFD; porous media; volume forces; heat exchanger; vacuum dewatering; time efficient simulations; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Throughout recent years, computer based programs have been applied to solve and analyse industrial problems encountered global fields such as automobile design for reduction of CO2-gas, designing wind parks aimed at increasing power output etc. One of these developed programs is Computational Fluid Dynamics (CFD) which numerically solves complex flow behaviour based on computer power.

  7. 10. Numerical methods for Sylvester-type matrix equations and nonlinear eigenvalue problems

    Författare :Emil Ringh; Elias Jarlebring; Johan Karlsson; Per Enqvist; Daniel Kressner; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matrix equations; Lyapunov equation; Sylvester equation; nonlinear eigenvalue problems; two-parameter eigenvalue problems; Krylov methods; iterative methods; preconditioning; projection methods; Matrisekvationer; Lyapunovekvationen; Sylvesterekvationen; ickelinjära egenvärdesproblem; två-parameters egenvärdesproblem; Krylovmetoder; iterativa metoder; förkonditionering; projektionsmetoder; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Optimization and Systems Theory; Optimeringslära och systemteori; Numerical Analysis; Numerisk analys;

    Sammanfattning : Linear matrix equations and nonlinear eigenvalue problems (NEP) appear in a wide variety of applications in science and engineering. Important special cases of the former are the Lyapunov equation, the Sylvester equation, and their respective generalizations. These appear, e.g. LÄS MER
