1. 21. Avverkningslagens tillämpning av metoden Spårlös drivning på Holmen Skog

   University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

   Author : Louise Sunnälv Persson; [2018]
   Keywords : körskador; kvalitativa intervjuer; traktplanering; traktdirektiv; kommunikation;

   Abstract : Körskador i samband med avverkning är ett problem inom skogsbruket. År 2012 togs en branschgemensam miljöpolicy om körskador på skogsmark fram och lade grunden till införandet av metoden Spårlös drivning på Holmen Skog under år 2013. READ MORE

3. 22. Jämförelse av två olika uppföljningsmetoder av miljöhänsyn hos Norra Skogsägarna

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Julia Bergström; Lisa Renman; [2018]
   Keywords : drivning; miljöhänsyn; körskador; uppföljning; planering;

   Abstract : Miljöhänsyn vid skogliga åtgärder har den senaste tiden varit en aktuell fråga inom skogsbruket. God miljöhänsyn vid avverkning minskar risken att negativt påverka omkringliggande miljöer i form av körskador som kan leda till exempelvis kvicksilverutlakning, tillväxtförluster och ökad slamtransport.

4. 23. Knowledge base and perception on sustainability in the long-haul transport sector in Brazil

   University essay from KTH/Energi och klimatstudier, ECS

   Author : Joel Alf Svensson; [2018]
   Keywords : Brazil; eco-driving; Euro classes; Heavy duty transport; Scania; long-haulage; logistics service providers; sustainability; trucks; energy efficiency;

   Abstract : demand for truck transportation is increasing and in the shadow the CO2 (carbon dioxide) emissions. In many parts of the world the majority of the transportation of goods is done by long-haulage trucks. More than 60% of all goods transported in Brazil are made by trucks (André Luiz Cunhaa, 2011).

5. 24. Investigation of Trench Gate IGBTs in MMC based VSC for HVDC

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Kruphalan Tamil Selva; [2018]
   Keywords : Trench-IGBT; VSC; HVDC; IGBT Driving Methods; Trench-IGBT; VSC; HVDC; IGBT drivningsmekanismer;

   Abstract : The following is a thesis project involving investigation of applicability of trench type IGBTs in present and future VSC based HVDC convertors. The work involves three major sections – theoretical loss evaluation of adoption of Trench technology (both IGBT and BIGT) for HVDC Light® applications, testing the Trench IGBT prototype with existing gate units and finalizing with a hypothesis and a practical solution for unexplained turn-on phenomenon observed during testing.

6. 25. Vibration caused by sheet pile driving- effect of driving equipment

   University essay from KTH/Jord- och bergmekanik

   Author : Haftom Tesfay Tsegay; [2018]
   Keywords : Ground vibration; vibratory driving; sheet pile; eccentric moment; markvibrationer; vibrerade drivning; spont; excentriska moment.;

   Abstract : In many construction works in urban areas vibratory driving is the most widely used technique toinstall sheet piles. But due to vibration-sensitive equipment and structures the amount of inducedground vibration need to be minimized. READ MORE
