   Abstract : Nowadays, the forestry industry still uses heavy machinery damaging both the forest and the soil. The start-up AirForestry is currently developing a sustainable way to thin and harvest trees. With their 6.2m wide electric drone carrying a harvesting tool, they can reach, thin, cut and carry trees without the need for access roads. READ MORE

3. 2. Vibration reduction over junctions in buildings

   University essay from KTH/Marcus Wallenberg Laboratoriet MWL

   Author : Alexander Forsberg; Aras Wali; [2021]
   Keywords : Vibration reduction; Junction; Building acoustics; Vibrations minskning; Knutpunkt; Byggnadsakustik;

   Abstract : Structure borne sound can travel multiple paths from one office to another and choosing to sound insulate a specific building element can be difficult since all the building elements are connected together and form a coupled system. The current approach by engineers when investigating transmission paths between spaces in a building is using a computer model and assuming that the junctions are firmly clamped or free. READ MORE

   Abstract : Facing global warming and its dramatic consequences, it is now of the utmost urgency to improve our understanding of the carbon cycle mechanisms through which global climate change unfolds. The MicroCarb mission will allow to accurately monitor CO2 global sources and sinks over the entire surface of the Earth. READ MORE

5. 4. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats

   University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion

   Author : Daniel Kostet; [2018]
   Keywords : ballasted track; bridge; elastic mat; expansion; finite element method FEM ; finite element analysis FEA ; floating slab mat; interaction; International union of railways UIC ; non-ballasted track; SOFiSTiK; ballasterat spår; ballastfritt spår; bro; dilatationsfogar; finita elementmetoden FEM ; finit elementanalys FEA ; fixerat spår; interaktion; Internationella järnvägsunionen UIC ; SOFiSTiK; vibrationer; vibrationsdämpande matta;

   Abstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. READ MORE

6. 5. Transmission Dynamics Modelling : Gear Whine Simulation Using AVL Excite
