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

   Författare :Michael Schweigler; Josef Eberhardsteiner; Thomas K. Bader; Thierry Descamps; Vienna University of Technology; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Core Acquisition Management in Remanufacturing : Current Status and Modeling Techniques

   Författare :Shuoguo Wei; Ou Tang; Erik Sundin; Jan Olhager; Moritz Fleischmann; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Core acquisition; remanufacturing; closed-loop supply chain; quantitative modeling; return uncertainties;

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

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

   Författare :Levon Saldamli; Peter Fritzson; Bernhard Bachmann; Francesco di Casella; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; PDEModelica; Modelica; object-oriented modeling; equation-based modeling; declarative modeling; high-level modeling languages; mathematical modeling languages; Computer science; Datavetenskap;

   Sammanfattning : 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. LÄS MER

5. 4. Numerical modeling of air-fiber flows

   Författare :Jelena Andric; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregation; particle-level simulation; rheology; fiber; dry-forming; fiber suspension;

   Sammanfattning : 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. LÄS MER

7. 5. Random and Hybrid Medium Access for M2M Communication : Scalability and Energy Analysis

   Författare :Luca Beltramelli; Mikael Gidlund; Patrik Österberg; Aamir Mahmood; Preben Mogensen; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; M2M; LoRa; IEEE 802.1ah; energy; mathematical modeling;

   Sammanfattning : The term machine-to-machine (M2M) communication identifies any fully automated communication between intelligent devices, autonomous from human intervention. M2M communication is a key enabling technology for the Internet of Things (IoT), where it is used to provide ubiquitous connectivity between a large number of intelligent devices. LÄS MER
