   Sammanfattning : The thesis focuses on the efficiency of the space heating system. In particular, the efficiency factors measure the efficiency of thermal zone. The efficiency factors measures how the energy is used in a space heating. LÄS MER

3. 12. On Pose Estimation in Room-Scaled Environments

   Författare :Hanna E. Nyqvist; Gustaf Hendeby; Fredrk Gustafsson; Isaac Skog; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Pose (position and orientation) tracking in room-scaled environments is an enabling technique for many applications. Today, virtual reality (vr) and augmented reality (ar) are two examples of such applications, receiving high interest both from the public and the research community. LÄS MER

   Författare :Sasan Sadrizadeh; Sture Holmberg; Christian Poelma; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Computational Fluid Dynamics CFD ; Ventilation System; Hospital Operating Room; Bacteria Carrying Particle; Surgical Site Infection; Colony Forming Unit; Airborne Particle Control; Air Quality; Thermal Comfort; Active-Passive Air Sampling methods; Computational Fluid Dynamics CFD ; ventilationssystem; operationssal på sjukhus; bakteriebärande partikel; infektion i samband med operation; kolonibildande enhet; kontroll av luftburna partiklar; luftkvalitet; termisk komfort; aktiva-passiva provtagningsmetoder för luft; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. LÄS MER

5. 14. Measures and method characteristics for early evaluation of safe operation in nuclear power plant control room systems

   Författare :Eva Simonsen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control room; early development; human factors engineering; safe operation; resilience engineering; evaluation methods; nuclear power;

   Sammanfattning : Safe operation is a central objective for high-risk industries such as nuclear power plants. Operation of the plant is managed from a central control room, which is a complex socio-technical system of physical and organisational structures such as operators, procedures, routines, and operator interfaces.

7. 15. Hydronic Heating Systems The Effect of Design on System Sensitivity

   Författare :Anders Trüschel; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shunt group; controllability; district heating; room temperature; air heater; heating coil; thermal power output; deviations; water return temperature; valve group; hydronic heating; radiator system; P-band;

   Sammanfattning : This thesis starts from the recognition that a hydronic heating system can be optimised, but can never be totally perfect. Sooner or later, in practice, deviations - caused by one or more components having slightly different characteristics or settings than they are assumed or supposed to have - arise. LÄS MER
