1. 1. Annealed Glass Failure Modelling : A Weakest-Link Approach with Statistical Analysis

   Författare :David Kinsella; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glass strength; structural glass; Weibull distribution; weakest-link system; statistical analysis; experimental tests; numerical modelling; finite element method; fracture mechanics;

   Sammanfattning : Novel and increased use of glass in building construction has been made possible, as a result of methods of mass production introduced during the 20th century and advanced computational structural analyses. With modern use of glass structures, a range of demands emerge which need to be addressed in the strength design process. LÄS MER

3. 2. “A chain is only as strong as its weakest link” : collaborative care planning as a person-centred practice

   Författare :Ingela Jobe; Åsa Engström; Birgitta Lindberg; Helle Wijk; Luleå tekniska universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; collaborative care planning; person-centred practice; health and social care; ethics; older adults; care partners; health and social care professionals; nursing; Nursing; Omvårdnad;

   Sammanfattning : In recent years, person-centred care has become one of the major goals of health and social care policies. A method used, to facilitate collaboration and integrate the person’s perspective in the decision-making process, is the collaborative care planning process. LÄS MER

4. 3. On Evaluation and Modelling of Human Exposure to Vibration and Shock on Planing High-Speed Craft

   Författare :Katrin Olausson; Karl Garme; Jakob Kuttenkeuler; Dominic J. Taunton; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whole-body vibration; high-speed craft; working conditions; seat modelling; apparent mass; ergonomics; human factors; ISO 2631-1; ISO 2631-5; extreme values; acceleration statistics; slamming;

   Sammanfattning : High speed in waves, necessary in for instance rescue or military operations, often result in severe loading on both the craft and the crew. To maximize the performance of the high-speed craft (HSC) system that the craft and crew constitute, balance between these loads is essential. LÄS MER

5. 4. Hydrolytic degradation of dental composites and effects of silane-treatment and filler fraction on compressive strength and thermal expansion of composites

   Författare :Karl-Johan M. Söderholm; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal frictional theory; filler-matrix debonding; stress-corrosion; stressinfluenced diffusion; m icro-crack form ation; crazing; opacity; wear; osmotic pressure; hoop stresses;

   Sammanfattning : Some researchers have suggested that the weakest link of dental composites is the filler-matrix bond. However, due to incompleteness of information dealing with this bond and its stability in a humid environment, it was considered desirable to investigate the effect of water on this region, as well as the influence of filler bonding and filler fraction on compressive strength and thermal expansionExperimental composites containing different filler fractions of either silane-treated or untreated fillers were made.

7. 5. Advanced measurement and modelling methods for noise source analysis

   Författare :Matti Rantatalo; Mats Åbom; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Sammanfattning : In daily life sound is a vital dimension for the perception of the world around us but can in some cases be considered as annoying, irritating, or even harmful. In these cases the sound is labelled as noise and can be addressed in two ways, either by insulating the noise problem from the receiver (person) or by altering the source. LÄS MER
