1. Norra polcirkelns uppvärmning och ännu varmare maktkapplöpning
Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionenSammanfattning : Today the climate in the arctic regions are changing at a rapid rate, faster than any speed previously recorded in human history but how is it impacting the geopolitical situation in these regions? New territory is being created by the ice melting and new natural resources are being found, how can this impact the current situation? This study looks at and discusses the current geopolitical situation in the Arctic using two theories from international relations, realism and liberalism and how the situation can develop using these theories. From a realist standpoint it is a balance of power held in check primarily by nuclear weapons. LÄS MER
2. Modeling of the trajectory of ice thrown from a wind turbine
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

3. Multifunctional ice and snow repellent coatings for photovoltaic modules
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/SolcellsteknikSammanfattning : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. LÄS MER
4. Väderförmildrande åtgärder för Sveriges nya stambanor- Analys av befintliga och nya åtgärder
Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och vägSammanfattning : Sverige står inför en mycket stor investering inom järnvägen. Nya stambanor kommer att koppla samman Sveriges stora regioner och samtidigt minska restiden mellan dem. Järnvägen ses även som ett klimatsmart resealternativ, vilket bidrar till att fler väljer att ta tåget framfört till exempel flyget. LÄS MER
5. Internal strain in the magnetocaloric alloy MnCoSi
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : Cooling systems based on magnetic refrigeration are a promising and environmentally friendly alternative to commonly used gas-compression refrigeration. Magnetic refrigeration is based on the magnetocaloric effect. LÄS MER
