1. 1. Riparian buffer zones widths, windthrows and recruitment of dead wood : A study of headwaters in northern Sweden

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

   Author : Gustaf Nilsson; [2021]
   Keywords : Fixed-width buffers; wind disturbance; small streams; nature consideration;

   Abstract : Riparian buffer zones, that is vegetated strips that are left surrounding streams, are today the general management practice to protect our running waters during forestry. They are created with the intent of preserving a variety of important ecological functions, including provision of dead wood. READ MORE

3. 2. Modelling of metal removal rate in titanium alloy milling

   University essay from Högskolan i Gävle/Maskinteknik

   Author : Niklas Andersson; [2018]
   Keywords : Titanium alloy; carbide; metamodeling; tool life; milling; Ti-6Al-4V;

   Abstract : Titanium is one of fourth most abundant structural metal in earths soil. It is in a composition with other elements, forming titanium alloys. These alloys are used in many different areas, such as medical, energy and sports, but is most commonly used in aerospace applications. READ MORE

4. 3. Spatial Modeling of Wildlife Crossing:GIS-based Approach for Identifying High-priority Locations of Defragmentation across Transport Corridors

   University essay from KTH/Geoinformatik

   Author : Josefine Jonsson; [2017]
   Keywords : wildlife crossing; GIS; Circuit Theory; habitat; defragmentation;

   Abstract : In this report, connectivity modeling has been performed using land cover data to find habitat pinch-points for deer along the study area Norrortsleden in Stockholm. Norrortsleden was chosen because there are a high number of deer accidents in the area, and is a priority area for action according to a barrier analysis for deer made by the Swedish Transport Administration.

5. 4. Skogens struktur och ekonomi över 100 år med fast eller varierad skyddszon runt vattendrag

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

   Author : Anna Jonsson; Sofia Grahn; [2014]
   Keywords : Heureka PlanVis; DTW-index; digital höjdmodell DEM ; rekreationsindex; lövskog;

   Abstract : Skogsbruksåtgärder intill vatten kan ge negativa konsekvenser på vattenkvalitén. Ett sätt att minska den negativa påverkan är att skapa skyddszoner. I denna studie simulerades olika skyddszoner i Heureka PlanVis och utvärderades med avseende på ekologiska, ekonomiska och sociala värden sett över längre tid. READ MORE

6. 5. Numerical simulations of the Cordilleran Ice Sheet (CIS) : Implementing a new module to the ice code ARCTIC-TARAH

   University essay from Institutionen för informationsteknologi

   Author : Asako Fujisaki; [2013]
   Keywords : ;

   Abstract : Paleoglaciology is an area of research where numerical reconstruction is actively used to understand the process of ice sheet growth and decay throughout past glacial periods, and numerical simulation of ice dynamics is a tool to reproduce the behaviors of the ice sheet and shelf under given conditions. ARCTIC-TARAH, designed by the Bolin Centre for Climate Research for simulating ice sheet dynamics, is developed based on the Pennsylvania State University Ice sheet model (PSUI). READ MORE
