1. Utilisation of hardwood in cross-laminated timber - A numerical study on vibrations in floors
University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperAbstract : Cross-laminated timber (CLT) is an engineered wood product consisting of several layers of laminations bonded together with adhesives. In contrast to heavier construction materials, timber and other lightweight building materials are more prone to serviceability issues due to vibrations. READ MORE

2. Multibody modelling of the vibrations in an aircraft engine
University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikAbstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE

3. The role of location of low inertia in power systems
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.
