2. 1. Modular long-span timber structures : a systematic framework for buildable construction

   Author : Anders Björnfot; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Abstract : One of the identified reasons for the low amount of timber construction in Sweden is a general lack of knowledge about timber engineering and how timber can be used to its full advantage. One way for increased timber construction is the development of a cost-efficient and easy to comprehend building system. READ MORE

4. 2. Communicating long-span timber structures with 3D computer visualization

   Author : Henrik Janols; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Abstract : One of the reasons for the low amount of timber in construction is a general lack of knowledge about timber engineering and how timber can be used to its full advantage. In this thesis the focus is 3D computer visualisation (3D VIZ) of non-residential long-span timber structures, used for storage, industry and sports where 3D VIZ is defined as a process where a 3D-model is enhanced with environmental information e.

5. 3. Soil-Steel Composite Bridges : Research advances and application

   Author : Amer Wadi; Raid Karoumi; Lars Pettersson; Ian D. Moore; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Ultimate capacity; Avalanche load; Failure load; Low soil cover; Failure mechanism; Long-span; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Soil-steel composite bridges are considered competitive structures being an economical alternative to similar span concrete bridges. This frequently stimulates practitioners to push their design limits and expand the different areas of application including their performance in sloping terrain. READ MORE

6. 4. I-girder Composite Bridges with Lateral Bracing : Improved load distribution

   Author : Victor Vestman; Peter Collin; Robert Hällmark; Hans Petursson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; bridge; composite bridge; steel-concrete composite; I-girder; case study; horizontal trusses; lateral bracing; rehabilitation; strengthening; torsional stiffness; upgrading; Byggkonstruktion; Structural Engineering;

   Abstract : This thesis deals with the subject of lateral bracing between the bottom flanges of I-girder composite bridges. The focus is on the impact of adding lateral bracing on existing bridges, as well as on new bridges. READ MORE

7. 5. In Vivo Accuracy and Precision in Prosthodontics

   Author : Robert Nedelcu; Andreas Thor; Ingela Nyström; Pontus Olsson; Per Vult von Steyern; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; accuracy; precision; in vivo; digital impression; intraoral scanner; polyether impression; implant impression; framework misfit; fully edentulous; Oral and Maxillofacial Surgery; Käkkirurgi; Oral and Maxillofacial Surgery; Käkkirurgi;

   Abstract : Background: There has been a dramatic increase in commercially available intraoral scanners (IOS) in the last decade, offering to replace indirect digitization of models (MOD) fabricated from impressions (IMPR). IOS has benefits of less patient discomfort and a faster workflow to fabricate fixed dental prosthesis (FDP), and implant-supported prostheses (IFD). READ MORE
