1. 1. Data uncertinties in material flow analysis.Local case study and literature survey

   Författare :Lena Danius; KTH; []
   Nyckelord :data uncertainies; sensitivity analysis; material flow analysis; MFA; method to determine data uncertainties; case study; ComBox model; nitrogen flows;

   Sammanfattning : The aim of this thesis is to discuss and analyse the influenceof data uncertainties with regard to the reliability of materialflow analysis (MFA) studies. MFA, as a part of environmentalsystems analysis, is a method belonging to the research field ofindustrial ecology and more specifically industrial metabolism. LÄS MER

3. 2. Nuclear data uncertainty quantification and data assimilation for a lead-cooled fast reactor : Using integral experiments for improved accuracy

   Författare :Erwin Alhassan; Henrik Sjöstrand; Rochman Dimitri; Michael Österlund; Stephan Pomp; Oscar Cabellos; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Total Monte Carlo; ELECTRA; nuclear data; uncertainty propagation; integral experiments; nuclear data adjustment; uncertainty reduction;

   Sammanfattning : For the successful deployment of advanced nuclear systems and optimization of current reactor designs, high quality nuclear data are required. Before nuclear data can be used in applications they must first be evaluated, tested and validated against a set of integral experiments, and then converted into formats usable for applications.

4. 3. Statistical Methods for Computational Markets : Proportional Share Market Prediction and Admission Control

   Författare :Thomas Sandholm; Magnus Boman; Mark Baker; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Grid Computing; Performance Analysis; Workload Modeling; Middleware; Quality of Service; Prediction; Admission Control; Computer and systems science; Data- och systemvetenskap;

   Sammanfattning : We design, implement and evaluate statistical methods for managing uncertainty when consuming and provisioning resources in a federated computational market. To enable efficient allocation of resources in this environment, providers need to know consumers' risk preferences, and the expected future demand. LÄS MER

5. 4. From Strange to Charm : Meson production in electron-positron collisions

   Författare :Joachim Pettersson; Karin Schönning; Andrzej Kupsc; Simon Eidelman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hadronic decays; Light mesons; Charmonium; Meson production; BESIII; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

   Sammanfattning : Decays of pseudoscalar mesons into a lepton-antilepton pair are very rare within the Standard Model since they cannot proceed via a single photon process. The C-even neutral mesons can be produced in electron-positron collisions by a two-photon intermediate state. LÄS MER

7. 5. Energy Reduction of Robot Stations with Uncertainties

   Författare :Mattias Hovgard; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robot station; Stochastic uncertainties; Energy optimization; Industrial robot;

   Sammanfattning : This thesis aims to present a practical approach to reducing the energy use of industrial robot stations. The starting point of this work is different types of robot stations and production systems found in the automotive industry, such as welding stations and human-robot collaborative stations, and the aim is to find and verify methods of reducing the energy use in such systems.
