1. 26. Modeling and Control of Flexible Manipulators

   Författare :Stig Moberg; Svante Gunnarsson; Bruno Siciliano; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; identification; control; robot manipulator; DAE; flexible multibody dynamics; inverse dynamics; benchmark; Automatic control; Reglerteknik;

   Sammanfattning : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and product quality. Other reasons for using industrial robots are cost saving, and elimination of hazardous and unpleasant work. LÄS MER

3. 27. Modeling Quantum Cascade Lasers : The Challenge of Infra-Red Devices

   Författare :Martin Franckie; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Cascade Lasers; Non-equilibrium Green s functions; Modeling; semiconductor heterostructures; Quantum Cascade Lasers; Non-equilibrium Green s functions; THz radiation; infrared radiation; semiconductor heterostructures; Modeling Simulation Technology; Fysicumarkivet A:2016:Franckié;

   Sammanfattning : We live in a time of rapid scientific and technological advancement. People liv- ing 100 years ago could never dream of inventions like those having completely changed our way of life, and our perception of the world; computers, mobile phones, the Internet, space travel, unraveling the mysteries of the early universe and distant galaxies, and our insight into the microscopic world of quantum phe- nomena.

4. 28. Modeling of Vertical Shaft Impact Crushers

   Författare :Simon Grunditz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DEM; VSI; Energy Modeling; Breakage Modeling;

   Sammanfattning : One of the largest products in most civilized societies is concrete used to build various types of constructions. To create this product, a mixture of cement, chemical binders, and rock aggregates are combined and then poured into molds where it hardens. The sand part of the rock aggregates is either from natural sources or manufactured. LÄS MER

5. 29. A Study on Sandwich Structures : Development, Mechanical Characterization and Numerical Modeling

   Författare :Samuel Hammarberg; Pär Jonsén; Jörgen Kajberg; Simon Larsson; Dan Zenkert; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-High Strength Steel; UHSS; Sandwich; Micro-sandwich; Hybrix; Modeling; Composite; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Legislative demands force the automotive industry to reduce greenhouse gas (GHG) emissions. At the same time, crashworthiness must not be compromised. A ve-hicle’s GHG emissions, such as carbon dioxide, is dependent on its fuel consump-tion. Lowering the vehicle weight, reducing fuel consumption, will therefor reduce emissions. LÄS MER

7. 30. Imaging and modeling the cardiovascular system

   Författare :Elira Maksuti; Michael Broomé; Anna Bjällmark; Matilda Larsson; Martin Ugander; Patrick Segers; KTH; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cardiac pumping; diastolic function; hemodynamics; modeling; simulation; arterial stiffness; ultrasound; shear wave elastography.; Medical Technology; Medicinsk teknologi; Cardiac pumping;

   Sammanfattning : Understanding cardiac pumping function is crucial to guiding diagnosis, predicting outcomes of interventions, and designing medical devices that interact with the cardiovascular system.  Computer simulations of hemodynamics can show how the complex cardiovascular system is influenced by changes in single or multiple parameters and can be used to test clinical hypotheses.
