   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; active thermal micro-grid; substation operation; performance assessment; distributed heat resources; chauffage urbain basse température; micro-réseaux de chaleur urbains actifs; fonctionnement de la sous-station; évaluation de la performance; sources de chaleur distribuées; lågtemperatur fjärrvärme; aktiv fjärrvärmemikronät; fjärrvärmecentral operation; prestationsbedömning; distribuerada värmekällor; Energy Technology; Energiteknik;

   Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER

3. 7. Integration of BIM and 3D GIS for sustainable cadastre

   Författare :Jing Sun; Kent Eriksson; Lars Harrie; Jenny Paulsson; Milan Horemuz; Peter van Oosterom; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; BIM; 3D GIS; 3D cadastre; LADM; business ecosystem; cadastre ecosystem; sustainability; Geodesi; Geodesy;

   Sammanfattning : Building Information Modelling (BIM) has prominently innovated and digitalized buildingenvironment through digital representation of buildings, lifecycle process and managementfor involved actors. Rapidly developed from Geographical Information System (GIS) domain,three-dimensionally (3D) GIS provides powerful and comprehensive functions of planning,modelling, visualizing and analyzing 3D geodata in large scale.

4. 8. Intrinsically Proton-Conducting Benzimidazole Units Tethered to Different Polymer Chain Architectures

   Författare :Christian Persson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Kemiteknik och kemisk teknologi; Polymer technology; Chemical technology and engineering; Materiallära; materialteknik; Material technology; Makromolekylär kemi; Macromolecular chemistry; proton-exchange membrane fuel cell; structure diffusion; thiol-ene reaction; segmental mobility; high temperature; benzimidazole; block copolymers; polymer electrolyte; anhydrous proton conductivity;

   Sammanfattning : Proton transport is a fundamental process that can be found in many systems in nature, as well as in technical devices, such as fuel cells, electrochromic devices and various types of sensors. Fuel cell technology is considered as environmentally friendly because fuel cells are not limited by the Carnot cycle, and efficiently converts chemical energy into electrical energy which can be used for powering cars, laptops, buildings etc. LÄS MER

5. 9. Harmonisation of 3D geodata : a prerequisite for a digital information flow for applications in the planning and building sector

   Författare :Helen Eriksson; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data harmonisation; schema extension; 3D buildings; 3D city models; GeoBIM; lifecycle and version management; emporal information; user requirements; Guidelines; Hydrography;

   Sammanfattning : Data harmonisation is a prerequisite for smart cities, for a more efficient information flow in the planning and building process and for many applications in the urban environment. Ideally, data harmonisation will result in a digital information flow that include information from the whole lifecycle of a feature, for example for buildings, roads and tunnels. LÄS MER
