1. Granular Materials for Transport Infrastructures : Mechanical performance of coarse–fine mixtures for unbound layers through DEM analysis
Abstract : Granular materials are widely used as unbound layers within the infrastructure system playing a significant role on performance and maintenance. However, fields like pavement and railway engineering still heavily rely on empirically-based models owing to the complex behaviour of these materials, which partly stems from their discrete nature.

2. DEM Modelling of Unbound Granular Materials for Transport Infrastructures : On soil fabric and rockfill embankments
Abstract : Unbound granular materials (UGM) are widely used as load-bearing layers and for embankment construction within transport infrastructures. These play a significant role on operation and maintenance of transportation systems. However, pavement and railway engineering still today rely heavily on empirical models based on macroscopic observations. READ MORE

3. Advanced methods for the calibration of optical tweezers
Abstract : Optiska pincetter har sedan Arthur Ashkin och hans kollegors uppfinning på 1980-talet möjliggjort noggrann manipulation av mikroskopiska partiklar. Denna teknik har haft betydande inverkan inom flera områden, inklusive biologi, fysik, nanoteknik, spektroskopi, mjuka material och nanotermodynamik. READ MORE

4. Strategies for improving kraftliner pulp properties
Abstract : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. READ MORE

5. Local variation in bending stiffness in structural timber of Norway spruce : for the purpose of strength grading
Abstract : Most strength grading machines on the European market use an averagemodulus of elasticity (MOE), estimated on a relatively large distance along awood member, as the indicating property (IP) to bending strength. Theaccuracy of such grading machines in terms of coefficient of determination israther low at R2 ≈ 0.5. READ MORE
