3. 7. Investigations of passive safety systems in LWRs : melt coolability with bottom coolant injection, light gas effects on a passive containment cooling system

   Författare :Domenico Paladdino; KTH; []
   Nyckelord :;

   Sammanfattning : The key objectives in introducing passive features in thesafety systems for Light Water Reactor (LWR) are to increasetheir reliability, to simplify the design of the plants and toimprove performance and economics. Component and integralsystem tests in scaled facilities are required for optimizingthe design and for certification of these safety systems. LÄS MER

4. 8. Dynamic response reconstruction using passive components

   Författare :Anders Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

   Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER

5. 9. Approaches to energy efficient building development : studying under Chinese contexts

   Författare :Zhenhong Gu; Ronald Wennersten; Per Heiselberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; China; Passive House; Low Exergy system; Built Environmental Assessment; LCA; Swedish housing; Hammarby Sjöstad; Eco-village; Game theory; System theory; Soft Systems Methodology; Environmental engineering; Miljöteknik;

   Sammanfattning : This thesis presents a general description of approaches to energy efficient building development under Chinese contexts. The purpose of the work is to discuss how Chinese building development can be approved from an energy saving perspective. Building development is a complicated process that relates to many stakeholders’ interests. LÄS MER

7. 10. System-in-a-Package on Low-Cost Liquid Crystal Polymer Substrate

   Författare :Gang Zou; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FDTD; integrated passive components; ACA; liquid crystal polymer; FEM; flip-chip; RF; anisotropic conductive adhesive; system-in-a-package; system-on-a-package;

   Sammanfattning : System-in-a-Package (SiP) is one of the most advanced approaches to meet the requirements for future high-density electronics packaging. In this thesis, a 3D system-in-a-package concept with embedded active and passive components is proposed, where a liquid crystal polymer (LCP) was used as the base substrate. LÄS MER
