1. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

3. Evaluation of Models and Optimisation Methods for Energy Minimisation of Drill Riggs
University essay from Linköpings universitet/FordonssystemAbstract : There are many benefits from using electrical powertrains over diesel powertrains within the mining industries, where some of these benefits come from reducing the pollution within the mines and therefore improve the working environment as well as reduce the ventilation costs required from ventilating these pollution. It is also desired to optimise the use of the vehicle to increase the efficiency and reduce fuel consumption of the vehicle. READ MORE

4. Identification and strength classification of weakness zones in the Garpenberg mine based on measurement while drilling (MWD)
University essay from Luleå tekniska universitet/GeoteknologiAbstract : Boliden’s Garpenberg mine produces Zn-Pb-Ag(Cu-Au) using a sublevel stoping with pastefill mining method. The orebody is strongly affected by the existence of weakness zones mainly consisting of Talc Schist and Phlogopite Schist which affect the design, planning and production of the stope. READ MORE

5. Identifying Important Features to Minimize Hole Deviation in Percussive Drilling
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : Hole deviation is one of the most significant problems in drilling applications. Deviated holes result in inefficient blasting and have severe economic impacts due to increased equipment consumption. Conversely, straighter holes help in increasing production scales and reduce operational costs. READ MORE
