A procedure for automatic monitoring of control-loop performance is presented. The control loop performance monitor (CLPM) detects oscillations in the control loop. These oscillations are normally caused by too-high friction in the control valve, but there are other reasons as well. The CLPM is primarily intended to be connected to PID controllers, but it can also be connected to other controllers
I SvJT 1974 s. 18 behandlades rättsfrågor, som frihandelsavtalet mellan Sverige och EEC kunde förmodas aktualisera. Denna artikel uppdaterar bedömningen och sammanfattar erfarenheterna från den första treårsperioden efter att 2/3 av den förutsedda övergångsperioden för tullavveckling förflutit. Artikeln redogör för de svenska överskottet i bytesbalansen som förbytts i ett underskott; skyddsåtgärde
Regional cerebral blood flow was measured by the 133-xenon inhalation method during resting in 38 healthy men and 38 healthy women matched pairwise for age in the range 18-72 years. The results showed 11% higher global flow level in the women in all ages. A similar and significant regression of flow by age was seen for both sexes. The regional flow distribution also showed some sex-related differe
We extend the definition of the star product introduced by Lunin and Maldacena to study marginal deformations of N=4 SYM. The essential difference from the latter is that instead of considering U(1)xU(1) non-R-symmetry, with charges in a corresponding diagonal matrix, we consider two Z_3-symmetries followed by an SU(3) transformation, with resulting off-diagonal elements. From this procedure we ob
Urban living labs (ULLs) are emerging as a form of collective urban governance and experimentation to address sustainability challenges and opportunities created by urbanisation. ULLs have different goals, they are initiated by various actors, and they form different types of partnerships. There is no uniform ULL definition. However, many projects studying and testing living lab methodologies are
Fast and accurate collision detection between geometric bodies is essential in application areas like virtual reality, animation, simulation, games and robotics. In this work, we address the collision detection problem in applications where deformable bodies are used, which change their overall shape every time step of the simulation. We propose and evaluate suitable bounding volume trees for defo
Om ett monumentprojekt i London där personer får lov att inta en statys position under en timmas tid i Antony Gormleys projekt "One and Other".
När vi har ställt samman det här materialet, har vi tänkt på tre olika grupper av mottagare: De 36 personer som deltagit i Pacemaking Jönköping Det är ni som är de närmast berörda, och det mesta av materialet har ni själva skrivit. Både ni och era närm
This paper describes work in progress exploring influences of product form in design practice based on interviews with five industrial designers in southern Sweden. Participants were asked to list and compare different designers, and to explain how their respective characteristics affected product form. The findings indicate designers as shaped by traditions and acting not only to serve their clie
