1. 21. From CAD to FEA : A design automation perspective

   Författare :Roland Stolt; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Idealisation; CAD; Finite element analysis; mid-surfaces; KBES; Feature based modelling; knowledge based systems; TECHNOLOGY; TEKNIKVETENSKAP; Construction engineering; Konstruktionsteknik;

   Sammanfattning : CAD-models of parts produced by injection moulding or die-casting are often complex making the task of automated geometrical idealisation for finite element analysis difficult. Conventional tools for geometric idealisation are not ideal for the task, as will be shown in the thesis. LÄS MER

3. 22. Automatic Collection Selection using Machine Learning

   Författare :Noric Couderc; Programvaruteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software engineering; Machine Learning; Collection efficiency; Java;

   Sammanfattning : Most recent programming languages include a collection framework as part of their standard library (or runtime). Examples are Java, C#, Python and Ruby. The Java Collection Framework provides a number of collection classes, some of which implement the same abstract data type, which makes them interchangeable. LÄS MER

4. 23. CVD on Iron Powder - Using Fluidising Bed Techniques

   Författare :Lars Nilsson; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium oxide; alumina; chemical vapour deposition; eddy current losses; FBR; iron; fluidising bed reactor; powder; SiO2; SMC; TiO2; Al2O3; soft ma etic com sites; CVD;

   Sammanfattning : Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. LÄS MER

5. 24. On constitutive modelling of the compaction and sintering of cemented carbides

   Författare :Jan Brandt; Viggo Tvergaard; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The common manufacturing procedure for components of cemented carbide is a closed die cold compaction of a powder and a subsequent sintering of the compact to full density and strength.Major problems with the manufacturing process are the possible fracturing on ejection from the tooling and the distortion in the final shape.

7. 25. Technical cost modelling and efficient design of lightweight composites in structural applications

   Författare :Mathilda Karlsson Hagnell; Malin Åkermo; Dan Zenkert; Gerhard Ziegmann; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technical cost modelling; composite materials; carbon fibre; lightweight design; optimization; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : A lightweight transport design reduces fuel costs and emissions and can be achieved through the use of fibre-reinforced composite materials. Although lightweight, the composite raw material can be expensive and the sequential component production challenging and costly. LÄS MER
