2. 1. Renewable Energy in Energy-Efficient, Low-Pollution Systems

   Author : Bengt Johansson; Miljö- och energisystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Abstract : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. READ MORE

4. 2. Supervisory control for emission compliance of heavy-duty vehicles

   Author : Mohammed Razaul Karim; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; supervisory control; Euro VI emission legislation; exhaust aftertreatment system; Pontryagin’s minimum principle; E-NMPC.; Diesel engines;

   Abstract : Heavy freight trucks globally contribute to a significant proportion of transport-related air pollution. The dominant air pollutants from heavy freight trucks with diesel engine and exhaust aftertreatment system (EATS) are CO2, hydrocarbons (HC), CO, particulate matter (PM), NOX (NO and NO2), and NH3.

5. 3. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction

   Author : Mladen Čičić; Karl Henrik Johansson; Miroslav Krstić; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic control; Lagrangian control; mixed traffic models; Intelligent Transportation Systems; Connected and Automated Vehicles; traffic congestion; platoon coordination; moving bottlenecks; bottleneck decongestion; stop-and-go wave dissipation; traffic state reconstruction; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Traffic congestion is a constantly growing problem, with a wide array of negative effects on the society, from wasted time and productivity to elevated air pollution and reduction of safety. The introduction of connected, autonomous vehicles enables a new, Lagrangian paradigm for sensing andcontrolling the traffic, by directly using connected vehicles inside the traffic flow, as opposed to the classical, Eulerian paradigm, which relies on stationary equipment on the road.

6. 4. Dynamics of Energy Systems - Methods of analysing technology change

   Author : Lena Neij; Internationella miljöinstitutet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Abstract : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. READ MORE

7. 5. Tourism, Ecosystem Functions, and Human-Environmental Relations

   Author : Stefan Gössling; Institutionen för tjänstevetenskap; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social geography; Ecology; Zanzibar; world system theory; sustainable tourism; sustainable development; rainforests; human-environmental relations; groundwater; environmental consciousness; ecotourism; ecosystem functions; economic transition; cost-benefit analysis; coastal zone management; coastal communities; climate change; Air-traffic; biodiversity; Environmental technology; pollution control; Ekologi; Zanzibar; Socialgeografi; Miljöteknik; kontroll av utsläpp;

   Abstract : The thesis aims at deconstructing the sustainable tourism paradigm: can tourism be "a global strategy for sustainable development", as the tourist industry claims? And will developing countries in particular profit from tourism development?To most international organizations and institutions (from the World Wide Fund for Nature to The World Bank), tourism, if carefully managed, is a positive, sustainable development tool. However, the research presented in this thesis exposes this view as unrealistically optimistic for at least three reasons: first of all, global environmental change caused by tourism has never been investigated and integrated with the discourse on sustainable tourism development.
