1. 1. Vibrational Response Reconstruction and Model Validation

   Författare :Anders Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; error metrics; response reconstruction; controllability; rig test; drive signal identification; inverse problems; model validation; state space; model updating;

   Sammanfattning : In this thesis, laboratory response reconstruction andcomputational model validation is investigated. The former concernsapplications of control theory as the objective is to reproduce acertain loading for a known component, while the latter concernsoptimization of a parameterized model as the objective is to modifya computational model to mimic a certain component's behavior.

3. 2. Long-Term Simulation of Coastal Evolution

   Författare :Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

   Sammanfattning : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. LÄS MER

4. 3. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine

   Författare :Göran Almkvist; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic; A F; model; transient; air to fuel; response; time constant; film; behavior; lambda; time-delay; fuel; mass; deposit factor;

   Sammanfattning : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. LÄS MER

5. 4. 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

7. 5. Oxidative Dissolution of Spent Fuel and Release of Nuclides from a Copper/Iron Canister : Model Developments and Applications

   Författare :Longcheng Liu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model; oxidative dissolution; spent fuel; radiolysis; release; mass transport; radionuclide; hydrogen; corrosion; canister; near field; repository; Chemical engineering; Kemiteknik;

   Sammanfattning : Three models have been developed and applied in the performance assessment of a final repository. They are based on accepted theories and experimental results for known and possible mechanisms that may dominate in the oxidative dissolution of spent fuel and the release of nuclides from a canister.
