  2. 21. On failure of high strength steel bridge roller bearings

    Author : Pourya Noury; Ove Lagerqvist; Kjell Eriksson; John Yates; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Abstract : This thesis is concerned with failure analysis of high strength steel bridge roller bearings.Paper Adescribes how the commonly used Hertz formulas for contact stresses underestimate the actual stresses in practice due to temperature differences, misalignments and other construction-related conditions.

  4. 22. On healing of titanium implants in iliac crest bone grafts

    Author : Mats Sjöström; Stefan Lundgren; Lars Sennerby; Christian Lindqvist; Umeå universitet; []
    Keywords : Surgery; Edentulous atrophic maxilla; Autogenous bone graft; Endosteal implants; Microimplants; Resonance frequency analysis; Implant survival; Graft volume changes; Kirurgi; odontologi; Odontology;

    Abstract : Bone grafts and titanium implants are commonly used for surgical/prosthetic rehabilitation of the atrophic edentulous maxilla. The factors which influence bone graft healing and implant integration are not sufficiently understood. READ MORE

  5. 23. Radiographic follow-up analysis of Br?nemark? dental implants

    Author : Solweig Sundén Pikner; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cluster effect; Dental implants; Dependency; Diagnostic accuracy; Long-term follow-up; Marginal bone level; Observer variation; Osseointegration; Prediction;

    Abstract : Radiography plays an important role in clinical routine practice and in research projects evaluating dental implants, among them Br?nemark? System. Presence of a peri-implant radiolucency has been used in studies as a criterion for implant failure without knowledge of its diagnostic accuracy. READ MORE

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

    Author : Yu Yang; Ahmed Hemani; Zhonghai Lu; Madhura Purnaprajna; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 25. On the role of number of fixtures, surgical technique and timing of loading

    Author : Alf Eliasson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Computer numerical control; dental implants; fixed prostheses; non-submerged; CNC-milling;

    Abstract : Aims: The aims of this thesis were to analyze reduced number of implants supporting full arch fixed mandibular prostheses and fixed partial dentures (FPDs), non-submerged healing and early loading in the edentulous mandible. A further aim was to evaluate fit of Computer Numerical Control (CNC)-milled I-Bridge? frameworks. READ MORE
