1. 11. Getting physical : tangibles in a distributed virtual environment

   Författare :Mattias Bergström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Funktionella produkter; Functional Product Development;

   Sammanfattning : The design of products is an increasingly complex task, where companies do not have and do not want the in-house competence to manage the development of entire products. Consequently, companies outsource parts of product development projects to other companies or join in partnerships. LÄS MER

3. 12. Integration and communication of engineering information in collaborative design

   Författare :Haoxue Ma; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Sammanfattning : In recent years, the rapid development of computer technologies has greatly impacted the product development process. In the engineering area, powerful computer-based tools such as Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) systems enable engineers to fulfil various design tasks and realise product concepts in the early phase of the product development process, without physical parts actually being manufactured.

4. 13. On Functional Tolerances in Machine Design

   Författare :Rikard Söderberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; loss functions; tolerance chains; quality loss; computer aided tolerancing; manufacturing cost; functional tolerances; quality; tolerances;

   Sammanfattning : This thesis describes a method that allows tolerances on critical dimensions to be assigned with respect to both quality and manufacturing cost. To be able to quantify and include customer needs in the process of assigning tolerances, the concept of functionality loss is used. LÄS MER

5. 14. High-Level Synthesis for SiLago : Advances in Optimization of High-Level Synthesis Tool and Neural Network Algorithms

   Författare :Yu Yang; Ahmed Hemani; Zhonghai Lu; Madhura Purnaprajna; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic Design Automation EDA ; Computer Aided Design CAD ; Algorithm-level Synthesis; SiLago; Optimization Techniques; Neural Network; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Embedded hardware designs and their automation improve energy and engineering efficiency. However, these two goals are often contradictory. The attempts to improve energy efficiency often come at the cost of engineering efficiency and vice-versa. High-level synthesis (HLS) is a good example of this challenge. LÄS MER

7. 15. Modeller och modellering med digitala verktyg i högstadiets teknikundervisning

   Författare :Helen Brink; Niklas Gericke; Nina Kilbrink; Jonas Hallström; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Modeller; Modellering; Digitala verktyg; Tekniklärare; Teknikundervisning; CAD; Fenomenografi; Livsvärldsfenomenologi; Pedagogiskt arbete; Educational Work;

   Sammanfattning : This licentiate thesis is about secondary school technology teachers’ experiences of teaching with models and modelling using digital tools.The aim of this thesis is to gain new in-depth knowledge of teaching in relation to digital models and digital modelling, and create better preconditions for technology teachers when it comes to their choices of content and methods of teaching in the area.
