1. 1. Sampling uncertainties in ensemble weather forecasting

   Författare :Linus Magnusson; Erland Källén; Jonas Nycander; Jan Barkmeijer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ensemble forecasting; Initial perturbation techniques; Meteorology; Meteorologi; meteorologi; Meteorology;

   Sammanfattning : The aim of ensemble weather forecasting is to provide probability forecasts for the occurrence of meteorological events. The ensembles are constructed by assembling several forecast realisations, each member of the ensemble being constructed to sample the uncertainties in the forecast. LÄS MER

3. 2. Characterization and forecasting of wind conditions over the Baltic Sea

   Författare :Christoffer Hallgren; Erik Sahlée; Julie Lundquist; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; forecasting; low-level jet; lidar; machine learning; mesoscale meteorology; numerical weather prediction; post-processing; reanalysis; sea breeze; turbulence; wind atlas; wind energy; wind power; Meteorologi; Meteorology;

   Sammanfattning : To meet the increasing demand of sustainably produced electricity, the total number of installed wind turbines is rapidly increasing globally. Although onshore installations are dominating, offshore wind power is taking a greater share of the market every year. LÄS MER

4. 3. From data to decision - learning by probabilistic risk analysis of biological invasions

   Författare :Ullrika Sahlin; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; probabilistic models; establishment success; prediction; forecasting; uncertainty; risk; invasive species; Bayesian methods;

   Sammanfattning : Predicting an uncertain future with uncertain knowledge is a challenge. The success of efforts to preserve biodiversity, to maintain biosecurity and to reduce a negative impact from climate change, depend on scientifically based predictions of future events. LÄS MER

5. 4. Spatio-temporal forecasting and optimization for integration of solar energy in urban energy systems

   Författare :Dennis van der Meer; Joakim Widén; Pierre Pinson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forecasting; photovoltaic; electricity use; net load; probabilistic; multivariate; optimization; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Sammanfattning : The increasing penetration of non-dispatchable renewable energy sources such as photovoltaic (PV) systems in the electricity generating mix poses challenges to the operational performance of the power system. On the demand side, advanced schemes that increase the flexibility of customer loads and the increase in electrification are set to noticeably alter electricity demand. LÄS MER

7. 5. Towards forecasting epigenetic repression

   Författare :Moa J. Lundkvist; Yuri B. Schwartz; Ludvig Lizana; Peter V. Kharchenko; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; epigenetics; Polycomb; PRC1; PRC2; H3K27 methylation; Monte-Carlo simulation; chromatin structure; Drosophila; molekylär bioteknik inst f molekylärbiologi ; molecular biotechnology dept of molecular biology ;

   Sammanfattning : Multicellular organisms form many different cell types from one genome, which requires differential gene activity. The Polycomb system upholds the correct gene expression programs by epigenetically silencing genes that encode critical transcription regulators. LÄS MER
