2. 1. Automation of front-end loaders : electronic self leveling and payload estimation

   Author : I Yung; Leonid Freidovich; Sven Rönnbäck; Carlos Vázquez; Tomas Nygren; Heikki Handroos; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Front-End Loaders; Electronic Self Leveling; Modeling; Control; Disturbance estimation; Payload estimation; Equations of motion; Pressure-based friction;

   Abstract : A growing population is driving automatization in agricultural industry to strive for more productive arable land. Being part of this process, this work is aimed to investigate the possibility to implement sensor-based automation in a particular system called Front End Loader, which is a lifting arms that is commonly mounted on the front of a tractor.

4. 2. Particulate Debris Spreading and Coolability

   Author : Simone Basso; Pavel Kudinov; Florian Fichot; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-leveling; debris bed; spreading; coolability; severe accident; probabilistic framework; Monte Carlo; uncertainty; sensitivity; Fysik; Physics;

   Abstract : In Nordic design of boiling water reactors, a deep water pool under the reactor vessel is employed for the core melt fragmentation and the long term cooling of decay heated corium debris in case of a severe accident. To assess the effectiveness of such accident management strategy the Risk-Oriented Accident Analysis Methodology has been proposed. READ MORE

5. 3. Determination of Land uplift in Areas not covered by Repeated Levellings with application to South-Norway

   Author : Jan Danielsen; Lars Sjöberg; KTH; []
   Keywords : ;

   Abstract :  The fennoscandia post glacial uplift rate of today, the time averaged vertical velocity, is usually determined by mareographs and repeated leveling. We consider situations where parts of the levelling not are observed only once. READ MORE

6. 4. Moisture redistribution in screeded concrete slabs

   Author : Magnus Åhs; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hysteresis; Scanning; Relative humidity; Moisture redistribution; Sorption isotherms; Screeded slab;

   Abstract : The principal objective for this licentiate thesis is to develop a methodology and evaluation model in order to make the future relative humidity in a screeded concrete slab predictable. Residual moisture in screeded concrete slabs may redistribute to the top screed surface under semi-permeable flooring, thus elevating the relative humidity, RH, and possibly exceed the critical humidity level.

7. 5. The Rhetoric of Pravda Editorials : A Diachronic Study of a Political Genre

   Author : Ludmila Pöppel; Milan Bily; Anatolii Shaikevich; Dmitrii Dobrovolskii; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; political discourse; discourse analysis; language of revolution; totalitarian language; Soviet political language; Pravda editorials; rhetorical changes; Slavic languages; Slaviska språk; slaviska språk; Slavic Languages;

   Abstract : The present study considers the diachronic changes that took place in Soviet political discourse as reflected in six selections of Pravda editorials from the 1920s through the 1950s, as well as slogans and headlines in that newspaper from 1917 through 1933. The principal goal of analyses conducted on various levels is to identify and investigate a number of tendencies demonstrating the gradual transformation of the language of revolution into totalitarian language.
