2. 6. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation

   Author : Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Ingo Hansen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway operation; Railway capacity; Single-track; Double-track; Partial double-track; Inter-station distance; Delay; Delay propagation; Crossing; Overtaking; Timetable flexibility; Simulation; Experimental design; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. READ MORE

4. 7. Two Topics in Survey Methodology : Inference from Nonprobability Samples Using the Double Samples Setup

   Author : Boris Lorenc; Daniel Thorburn; Lars Lyberg; Gösta Forsman; Stockholms universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; response process; establishment surveys; socially distributed cognition; response burden; measurement error; nonprobability samples; web surveys; double samples; propensity scores; model-based estimation; imputation; nonparametric imputation; weighting; Surveying; Lantmäteri;

   Abstract : Modelling the response process in establishment surveys proceeded thus far by adding steps of operational character to the core cognitive steps of the individual cognitive model. Here (Paper 1) a larger unit of the cognitive analysis is posited: that part of the enterprise that is engaged in responding to a survey, consisting of one or more employees, the tools they use and the established practices of record keeping and survey responding.

5. 8. Airborne sound insulation of single and double plate constructions

   Author : Ulrica Kernen; Gudni Jóhannesson; Waldemar Maysenhölder; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; : Airborne sound insulation; single plate; double plate; floating-floor; sound reduction index; sound transmission.; Byggnadsteknik; Building engineering; Byggnadsteknik;

   Abstract : The sound insulation demands for dwellings and public building has increased over the years as the number of sound sources has grown. From the outside our homes are exposed to noise from cars, trains, airplanes, etc. Noise intrudes from our neighbours and their television and stereo equipments. READ MORE

6. 9. Double Pion Production in the dd to αππ reaction

   Author : Samson Keleta; Pia Thörngren Engblom; Bo Höistad; Hans Ströher; Uppsala universitet; []
   Keywords : Nuclear physics; ABC effect; double pion; Kärnfysik; Nuclear Physics; kärnfysik;

   Abstract : The reaction dd → 4Heππ has been measured exclusively for the first time. The measurements were performed at Td = 712 MeV and Td = 1029 MeV, with the WASA detector assembly at CELSIUS (Uppsala-Sweden). The aim was to investigate a long standing puzzle, the so called ABC effect. READ MORE

7. 10. Shear walls with double plasterboards : evalutation of design models

   Author : Tomas Filipsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : This thesis presents a part of the ECSC-project Development of dry composite construction systems based on steel in residential application that focus on design recommendations for stabilizing buildings by using shear resistance in the walls. The existing design method suggested and used by the Swedish plasterboard manufacturer Gyproc AB is considered as a bit conservative and it does not consider double plasterboards properly. READ MORE
