  1. 1. Core Acquisition Management in Remanufacturing Current Status and Modeling Techniques

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Shuoguo Wei; Linköpings universitet.; Linköpings universitet.; [2015]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Core acquisition; remanufacturing; closed-loop supply chain; quantitative modeling; return uncertainties;

    Abstract : Remanufacturing is an important product recovery option that benefits our sustainable development. Cores, i.e. the used products/parts, are essential resources for remanufacturing. READ MORE

  2. 2. Nonlinear modeling of reinforced dowel joints in timber structures : a combined experimental-numerical study

    University dissertation from Vienna : Vienna University of Technology

    Author : Michael Schweigler; [2018]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology byts ev till Engineering ; Teknik; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Steel dowels are indispensable elements for the design of joints in modern timber structures. Dowels are broadly used because of their flexibility in design and easy assembling on-site, as well as due to their advantageous mechanical behavior. READ MORE

  3. 3. PDEModelica – A High-Level Language for Modeling with Partial Differential Equations

    University dissertation from Institutionen för datavetenskap

    Author : Levon Saldamli; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; PDEModelica; Modelica; object-oriented modeling; equation-based modeling; declarative modeling; high-level modeling languages; mathematical modeling languages; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : This thesis describes work on a new high-level mathematical modeling language and framework called PDEModelica for modeling with partial differential equations. It is an extension to the current Modelica modeling language for object-oriented, equation-based modeling based on differential and algebraic equations. READ MORE

  4. 4. Numerical modeling of air-fiber flows

    University dissertation from Institutionen för datavetenskap

    Author : Jelena Andric; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregation; particle-level simulation; rheology; fiber; dry-forming; fiber suspension;

    Abstract : The dynamics of fiber suspensions are of great importance in applications such as the dry-forming process of pulp mats for use in hygiene products. In this forming process, fibers are transported in flowing air. The fibers interact with the fluid, and may interact with each other and interlock in flocs. READ MORE

  5. 5. Response of cable-stayed and suspension bridges to moving vehicles Analysis methods and practical modeling techniques

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Raid Karoumi; KTH.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cable-stayed bridge; suspension bridge; Great Belt suspension bridge; bridge moving loads; traffic-induced vibrations bridge-vehicle interaction; dynamic analysis; cable element; finite element analysis; finite diffrence method; tuned mass damper; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis presents a state-of-the-art-review and twodifferent approaches for solving the moving load problem ofcable-stayed and suspension bridges.The first approach uses a simplified analysis method tostudy the dynamic response of simple cable-stayed bridgemodels. READ MORE
