1. 1. Toward Carbon based NEMS

   Författare :Farzan Alavian Ghavanini; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes CNT ; Nanoelectromechanical systems; and CMOS compatibility ; CNT-based switch; vertically aligned carbon nanofibers VACNF ; NEMS;

   Sammanfattning : A systematic analysis and assessment of carbon nanotube (CNT) based NEMS switches is presented and their features are compared to typical complementary metal-oxide-semiconductor (CMOS) performance parameters. It is shown that CNT-based switches with considerably smaller leakage current compared to CMOS switches can be realized. LÄS MER

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

   Författare :Maria Grahn; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy prices; CSP; CO2 emissions; hydrogen; CCS; carbon tax; biomass; carbon leakage; liquid biofuels; global energy systems modeling; transportation; passenger vehicles;

   Sammanfattning : This thesis analyzes future fuel and technology choices focusing on transport in a carbon constrained world. The analysis tool used in all five appended papers is the cost-minimizing Global Energy Transition (GET) model. LÄS MER

4. 3. Process Models for CO2 Migration and Leakage : Gas Transport, Pore-Scale Displacement and Effects of Impurities

   Författare :Farzad Basirat; Auli Niemi; Karsten Jensen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geological Carbon Storage; CO2 leakage; Field experiment; Laboratory experiment design; Multi-phase flow; Heterogeneity; Wettability; Pore-scale modeling; Impurity gases; Hydrology; Hydrologi;

   Sammanfattning : Geological Carbon Storage (GCS) is considered as one of the key techniques to reduce the rate of atmospheric emissions of CO2 and thereby to contribute to controlling the global warming. A successful application of a GCS project requires the capability of the formation to trap CO2 for a long term. LÄS MER

5. 4. Transport and environment incentive policy instruments : effects and interactions

   Författare :Xing Liu; Lars Hultkrantz; James Odeck; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Congestion pricing; Equity effects; Modal choice; Social marginal cost; Externalities; Transport taxation; Carbon tax; Carbon leakage; Computable General Equilibrium Model; VTTS; Simultaneous decision model; Random utility model; Logistics cost minimization; Additionality; Klimp; Climate subsidy program; Subsidy; CDM; Business Studies; Företagsekonomi;

   Sammanfattning : This dissertation studies issues related to the evaluation of the effects and interactions of transport and environmental incentive policy instruments. Essay 1: Green cars sterilize congestion charges: a model analysis of the reduced impact of Stockholm road tolls calibrates a modal-choice model with data from the Stockholm road toll and uses it to study the sensitivity of congestion toll effects to some seemly subtle changes in the toll system design and external circumstances.

7. 5. Carbon Dioxide in Supermarket Refrigeration

   Författare :Samer Sawalha; Björn Palm; Eckhard Groll; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2; carbon dioxide; refrigeration system; supermarket; cascade; indirect; trans-critical; modelling; simulation; experiment; safety analysis; comparison; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : This thesis theoretically and experimentally investigates different aspects of the application of CO2 in supermarket refrigeration. Theoretical analysis has been performed using computer simulation models developed to simulate CO2 indirect, NH3/CO2 cascade, CO2 trans-critical and direct expansion (DX) R404A systems. LÄS MER
