1. Bearing condition monitoring : An investigation on the possibility of monitoring aging of the lubricating grease by means of acoustic emission and temperature.
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Grease is among the most widely used lubricants in rolling element bearings. Proper understanding of the effect of lubrication due to grease aging can provide a significant increase in the life of the engineering systems. However, at present, there is no sufficient understanding of the grease aging effect in rolling elements bearing. READ MORE

2. Modeling, Simulation and Correlation of Drag losses in a Power Transfer Unit of an All- Wheel Drive System
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : A Power Transfer Unit (PTU) of an All-Wheel Drive System is a hypoid gear transmission unit that distributes the power from the vehicle transmission to all wheels of the vehicle. This thesis aims at increasing the fidelity of the analytical power loss calculation methods through test data correlation and develop a 1D simulation model that can be used to evaluate the drag losses in the PTU at early design stages.

3. Drag Torque and Synchronization Modelling in a Dual Clutch Transmission
University essay from Lunds universitet/MaskinelementAbstract : Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process.

5. Adsorption of Cr(VI) on Mill Scale
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : Mill scale is a by-product from hot rolling of steel. It has a high content of iron oxide which has the ability to adsorb ions. Hexavalent chromium is a pollutant which could be adsorbed to mill scale. Different pre-treatment of the mill scale was tested to optimize the adsorption of hexavalent chromium. READ MORE
