  2. 1. Simulation-driven design : Motives, Means, and Opportunities

    Author : Ulf Sellgren; KTH; []
    Keywords : CAD; CAE; FE method; Metamodel; Object model; PDM; Physical behavior; System; Mechanical engineering; Maskinteknik;

    Abstract : Efficiency and innovative problem solving are contradictory requirements for productdevelopment (PD), and both requirements must be satisfied in companies that strive to remainor to become competitive. Efficiency is strongly related to ”doing things right”, whereasinnovative problem solving and creativity is focused on ”doing the right things”. READ MORE

  4. 2. Insight into coronary artery ectasia

    Author : Usama Boles; Michael Y. Henein; Peter Eriksson; Corrado Tamurino; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary artery ectasia; atherosclerosis; acute coronary syndrome; lipidomic profile; cytokines; prognosis of coronary artery ectasia; kardiologi; Cardiology;

    Abstract : Background:Coronary artery ectasia (CAE) is defined as a diffuse dilatation of the epicardial coronary arteries exceeding 1.5 folds the diameter of the normal adjacent arterial segment and/ or the remaining non-dilated part of the same artery. (1) The incidence of CAE has been variably reported between different nations and ranges between 1. READ MORE

  5. 3. Electrophysiological effects of contrast media. Dynamic vectorcardiographic monitoring of patients during coronary angiography

    Author : Agneta Flinck; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dynamic vectorcardiography; electrophysiology; contrast media; cardioangiography; adverse events;

    Abstract : Objective: The aims of this work were to study, by means of dynamic vectorcardiography (VCG), the electrophysiological effects of contrast media (CM) injected into the coronary arteries and to evaluate which VCG variables are most suitable for comparing different CM. We also studied if CM-induced VCG changes differ from those seen after myocardial ischaemia. READ MORE

  6. 4. Engineering information integration and application development using object-oriented mediator databases

    Author : Mattias Nyström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : The thesis deals with methods for efficient integration of engineering information sources, such as CAD and CAE systems, and application development in the product development process. The distributed and heterogeneous engineering computing environment of today does not provide sufficient interoperability between CAD and CAE systems. READ MORE

  7. 5. Metamodel-Based Multidisciplinary Design Optimization of Automotive Structures

    Author : Ann-Britt Ryberg; Larsgunnar Nilsson; Anirban Basudhar; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multidisciplinary design optimization MDO ; metamodel; artificial neural network ANN ; support vector machine SVM ; sequential sampling; crashworthiness; automotive structure; spot weld optimization;

    Abstract : Multidisciplinary design optimization (MDO) can be used in computer aided engineering (CAE) to efficiently improve and balance performance of automotive structures. However, large-scale MDO is not yet generally integrated within automotive product development due to several challenges, of which excessive computing times is the most important one. READ MORE
