In this paper, Modelica along with Optimica has been used to formulate and solve a minimum time optimization problem. The problem concerns traversing a given path with a robot in as short time possible under input constraints. Different problem reformulations are discussed that increase the chance of finding optimal solutions. This paper also discusses the use of these optimal solutions for contro
A method for determining evaporation rates and thermodynamic properties of aqueous solution droplets is introduced. The method combines evaporation rate measurements using modified TDMA technique with data evaluation using an accurate evaporation model. The first set of data has been collected and evaluated for succinic acid aqueous solution droplets. Evaporation rates of succinic acid solution d
Resfria möten (RM) är en samlingsterm för möten på distans, i realtid med teknikens hjälp, innefattande telefon-, webb- och videokonferens. Denna rapport beskriver svenska och internationella erfarenheter av dessa mötesformer med fokus på effekter på resandet och utsläpp av klimatgaser. Framtidsprojektioner för resfria mötens effekter 2030 och 2050 görs också.
Using the level crossing technique with parallel magnetic and electric fields the tensor polarizability of the 7 p 2 P 3/2 level in Rb 87 and the 8 p 2 P 3/2 level in Cs 133 was measured with the results α 2 (7 p 2 P 3/2 Rb 87 ) = -3.2 (2) MHz (kV/cm) 2 and α 2 (8 p 2 P 3/2 Rb 133 ) = -7.6 (3) MHz (kV/cm) 2 Theoretical values, calculated with the Coulomb approximation of Bates and Damgaard, agre
In the Akha language - a Tibeto-Burman language - marking of evidentiality is obligatory. The evidential system marks whether a statement is based on factual knowledge or inferred from seeing, hearing or feeling. It also marks whether the speaker makes a statement without being asked or as a result of a question or a reaction to something happening. The evidentials are marked by high tone for non-
Bodil Jönsson, nybliven hedersdoktor vid GU, funderar i sin gästkrönika över universitetens uppgift att skapa och ge bort kunskap.
