2. 1. Combined solar and pellet heating systems for single-family houses : How to achieve decreased electricity usage, increased system efficiency and increased solar gains

   Author : Tomas Persson; Per Lundqvist; Simon Furbo; Högskolan Dalarna; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin; Pellets; stove; boiler; solar heating; DHW preparation; system design; single-family house; electricity savings; Thermal energy engineering; Termisk energiteknik;

   Abstract : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. READ MORE

4. 2. Distributed Resources in a Re-Regulated Market Environment

   Author : Thomas Ackermann; KTH; []
   Keywords : Distributed Generation; Electricity Markets; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis analyses the value that distributed resources(DR) can contribute to an economically effcient operation of are-regulated electricity market and discusses the relevantchanges in the regulatory framework to allow the appropriatedevelopment of DR whenever DR may increase the economiceffciency of the electricity market. Distributed resources thereby combine two aspects:Distributed generation and demand-side resources. READ MORE

6. 4. Automation and traction control of articulated vehicles

   Author : Ulf Andersson; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Abstract : Articulated machines such as load-haul-dump machines, wheel loaders and haulers operate in many different environments and driving conditions. In particular they need to be able to perform well with road conditions and loads that can change drastically, setting hard requirements on performances and robustness. READ MORE

7. 5. Advancing the state of geospatial electrification modelling: New data, methods, applications, insight and electrification investment outlooks

   Abstract :  I skrivande stund uppskattas 860 miljoner människor globalt sakna tillgång till el. Målet att uppnå universal tillgång till el under det kommande decenniet – i enlighet med mål 7 av de globala målen för hållbar utveckling (SDG 7) – indikerar att många länder snart kommer att behöva införa riktlinjer, handlingsplaner och policys för att påskynda elektrifieringstakten.
