2. 1. Energy transition in transportation : Applying TIMES-based energy system optimisation models to sub-national levels

   Author : Jonas Forsberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Krister Sandberg; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system analysis; ESOM; Transportation; Climate change; Air quality; Energy Engineering; Energiteknik;

   Abstract : Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. READ MORE

4. 2. In the age of IoT : exploring public sector smartness

   Author : Ott Velsberg; Katrin Jonsson; Ulrika H. Westergren; Ulf Melin; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Internet of Things; Smartness; Public sector; data- och systemvetenskap; computer and systems sciences;

   Abstract : Smartness, which is emerging as a desirable attribute of governments, cities, and communities, has received heightened attention from researchers and practitioners. Smartness is a technology-centric view in which it is postulated that the public sector can become more resilient by adopting emergent technologies that improve efficiency, equality, citizen-centricity, transparency, collaboration, and security, thereby shaping the public sector to meet new demands and expectations.

5. 3. Usability in Transportation : Improving the analysis of cognitive work tasks

   Author : Mikael Erlandsson; Anders Jansson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

   Abstract : In most vehicle domains within the transportation sector, traffic is increasing and vehicles are becoming more technologically advanced. In addition to this, drivers are faced with conflicting goals, such as punctuality, maintaining safety, minimizing fuel consumption, ensuring passenger comfort, etc. READ MORE

6. 4. Cost-effective fuel choices in the transportation sector under stringent CO2-emission reduction targets - Global energy systems modelling

   Author : Maria Grahn; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Global energy systems; carbon dioxide emissions; biomass; liquid biofuels; primary energy price; transportation sector; hydrogen; carbon tax; energy scenarios;

   Abstract : This thesis analyzes the worlds future energy supply in general, and cost-effective fuel choices in the transportation sector in particular, under stringent CO2 constraints. The analysis is carried out with the help of a global energy systems model (GET), developed and modified specifically for each project. READ MORE

7. 5. Cost-effective fuel and technology choices in the transportation sector in a future carbon constrained world: Results from the Global Energy Transition (GET) model

   Author : Maria Grahn; Chalmers tekniska högskola; []
