2. 1. Modelling District Heating Network Costs

   Author : Luis Sánchez-García; Urban Persson; Helge Averfalk; Erik Möllerström; Marcus Thern; Magnus Åberg; Sweden Lund Lund University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District Heating; Pipe network; Cost analysis; Distribution Capital Cost; Effective Width; Plot Ratio; Heat Density; GIS; Smart Cities and Communities; Smarta städer och samhällen;

   Abstract : The solution of the undergoing climate and energy crises requires a radical transformation of the energy system, in which sustainability, no carbon emissions and energy efficiency ought to play a paramount role. This revolution should extend to all areas of the energy system, including the space heating and cooling sector, which accounts for a third of the European final energy demand and, in the European continent, it is still mostly supplied by fossil fuels.

4. 2. Self-Monitoring using Joint Human-Machine Learning : Algorithms and Applications

   Author : Ece Calikus; Sławomir Nowaczyk; Onur Dikmen; Stefan Byttner; Rita Ribeiro; Högskolan i Halmstad; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-monitoring; anomaly detection; machine learning;

   Abstract : The ability to diagnose deviations and predict faults effectively is an important task in various industrial domains for minimizing costs and productivity loss and also conserving environmental resources. However, the majority of the efforts for diagnostics are still carried out by human experts in a time-consuming and expensive manner. READ MORE

5. 3. Efficient driving of CBTC ATO operated trains

   Author : William Carvajal Carreño; Paloma Cucala García; Antonio Fernández-Cardador; Lennart Söder; Rafael Palacios Hielscher; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; CBTC signalling system; ATO; Metro; Ecodriving; NSGA-II-F; pseudo-Pareto front; Tracking algorithm; Fuzzy parameters; Moving-block; Train Simulation.; Electrical Engineering; Elektro- och systemteknik; Energy Technology; Energiteknik; Transportvetenskap; Transport Science;

   Abstract : Energy consumption reduction is one of the priorities of metro operators, due to financial cost and environmental impact. The new signalling system Communications-Based Train Control (CBTC) is being installed in new and upgraded metro lines to increase transportation capacity. READ MORE

6. 4. Improved Energy Efficiency in the Aluminium Industry and its Supply Chains

   Author : Joakim Haraldsson; Magnus Karlsson; Maria Johansson; Max Åhman; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Energy is an essential resource in the daily lives of humans. However, the extraction and use of energy has an impact on the environment. The industrial sector accounts for a large share of the global final energy use and greenhouse gas (GHG) emissions. The largest source of industrial GHG emissions is energy use. READ MORE

7. 5. Phosphate and Arsenic Cycling under Experimental Early Proterozoic Marine Conditions

   Author : Christoffer Hemmingsson; Iain Pitcairn; Ernest Chi Fru; Per Andersson; Christophe Dupraz; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; DIP; Early Proterozoic; coprecipitation; adsorption; Iron formations; BIF; geokemi; Geochemistry;

   Abstract : Nutrient dynamics in the Archean-Paleoproterozoic oceans strongly influenced primary productivity and the rise of atmospheric O2. Reconstructing the cycling of key nutrients such as dissolved inorganic phosphate (DIP) at this time is important for our understanding of the timing, rate and extent of atmospheric oxygenation at this time.
