  1. 1. Precipitation phase determination in cold region conceptual models - analysis and method development

    Författare :James Feiccabrino; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Snow Models; Precipitation Phase Uncertainty; ; Snow; Conceptual Model; Cold Regions;

    Sammanfattning : Precipitation phase uncertainty is a known source of error in conceptual models used for many hydrological, climatological, and environmental applications. These conceptual models often use the simple approach of calibrating an air temperature threshold (TRS) over a large area irrespective of physiographic characteristics such as distance to the ocean and topographic relief.

  3. 2. Computational Methods in Conceptual Structural Design

    Författare :Vedad Alic; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual design; conceptual structural design; ground-borne vibrations; form finding; optimization; dynamic relaxation; graphic statics; reciprocal figures; strut-and-tie; finite element method; isogeometric analysis; NURBS; CAD; numerical modelling;

    Sammanfattning : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. LÄS MER

  4. 3. Hg Cuprate Superconductors Technological and Conceptual Tools

    Författare :Rafael Gatt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mercury; high pressure; pulsed laser deposition; crystal growth; high temperature superconductors; cluster calculations; flat bands; thin oxide films; powder diffraction; structure refinement; phase transition; electronic structure; liquid phase epitaxy;

    Sammanfattning : This work concerns superconductivity in the cuprates. It touches some of the problems that this field displays. As a representing case, the Hg based cuprates are chosen. LÄS MER

  5. 4. Aircraft conceptual design methods

    Författare :Patrick Berry; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Generally aircraft conceptual design is defined as the starting point for concept sketcing and evaluation, but before that work can start an even earlier stage has to be covered.This is the stage where different scenarios are being worked through in which the aircraft as a platform is supposed to work.

  7. 5. Aircraft Systems Conceptual Design : An object-oriented approach from to

    Författare :Ingo Staack; Petter Krus; Frank Thielecke; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required of the nowadays complex system design. Namely the integration of models and simulations of different fidelity levels to enhance the analysis capability while maintaining a streamlined, transparent, and low cost working process is required.
