2. 11. Resource-Constrained Embedded Control and Computing Systems

   Author : Dan Henriksson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; reglerteknik; kontroll; Automation; robotics; control engineering; Automatiska system; numerisk analys; system; Datalogi; control; numerical analysis; systems; Computer science; Server control; Simulation tools; Feedback scheduling; Real-time control systems; Resource constraints;

   Abstract : This thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. READ MORE

4. 12. Laminar-flow Liquid-to-air Heat Exchangers - Energy-efficient Display Cabinet Applications

   Author : Caroline Haglund Stignor; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-efficiency; indirect cooling; display cabinet; pressure drop; heat transfer; flat-tube heat exchanger; cooling coil; laminar;

   Abstract : Provisions are stored and displayed in supermarkets and grocery stores, at a temperature lower than the ambient, in display cabinets, which are responsible for a significant amount of the energy use in this sector. During the 1990s, major changes in the regulations governing the use of synthetic refrigerants took place in Sweden. READ MORE

5. 13. Models for Estimation of Software Faults and Failures in Inspection and Test

   Author : Per Runeson; Institutioner vid LTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failures; usage based testing; usage model; statistical testing; faults; capture-recapture; inspections; software quality; software reliability; experiments; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

   Abstract : In software engineering, the quality of software and in particular the software reliability has to be controlled and improved. Hence there is a need for measuring and controlling the number and appearance of software faults and failures. READ MORE

6. 14. The relationship between rolling resistance and tyre operating conditions, with a focus on tyre temperature

   Author : Lisa Ydrefors; Annika Stensson Trigell; Jenny Jerrelind; Jurek Ejsmon; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rolling resistance; tyre temperature; brush model; parametrisation; rolling resistance measurement; drum measurements; operating conditions; tyre; flat track measurements; Rullmotstånd; rullmotståndsmätning; däcktemperatur; driftsförhållanden; trummätning; borstmodellen; parametrisering; däck; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : Efforts to reduce greenhouse gas emissions from today’s increasing number of cars and trucks, are crucial in counteracting global warming. These efforts include the intent to reduce the effects of the resistive forces acting on the vehicle. Rolling resistance is one of these forces. READ MORE

7. 15. Towards a sustainable automotive industry : experiences from the development of emission control systems

   Author : David Bauner; Staffan Laestadius; Lee Schipper; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evolutionary economics; environmental innovation; trajectories; co-evolution; Industrial engineering and economy; Industriell teknik och ekonomi;

   Abstract : From the mid-1970s and on, the contribution to air pollution of carbon monoxide, hydrocarbons and nitrogen oxides from gasoline passenger cars in the developed world has been reduced through co-evolution of regulation and commercial introduction of catalytic emission control technology, now part of hundreds of millions of cars, trucks and buses worldwide. This dissertation is a disaggregated study of the global introduction of catalytic emission control technology as a measure to reduce local air pollution. READ MORE
