A Predictive PI Controller for Processes with Long Dead Times

A predictive PI (proportional-integral) controller with dead-time compensation is described. Its advantage compared with previous dead-time compensating controllers is that although it also contains five parameters, only three are adjusted by the operator, namely, the gain, the integral time and the dead time. The controller is also suited for processes with varying dead times. Conceptually, the n

A Study of Number-Ratio Fluctuations in Gold-Gold Interactions at sqrt(s_NN)=200 GeV

Popular Abstract in Swedish Experimentella data från kollisioner mellan guldjoner vid hög energi har analyserat inom ramen för experimentet PHENIX, som finns vid en av kollisionspunkterna vid ''the Relativistic Heavy-Ion Collider'' på ''Brookhaven National Laboratory'', New York (USA). Kollisioner med tunga joner, så som guld, används i försök till att återskapa de förhållanden som fanns i univerThe properties of the basic building blocks of nuclear matter, the quarks, and their interactions are not known in detail, largely because observations are complicated by the confinement of quarks in composite particles. New insights can be gained from the study of nuclear matter in a deconfined phase, like the form of matter that the Universe consited of early in its evolution according to the Bi

Constraints on the temporal dispersion of passive metamaterials

Metamaterial applications such as cloaking, perfect lenses, and artificial permeability are restricted by the frequency dependence of the permittivity, permeability, and index of refraction. Here, causality and passivity together with integral identities for Herglotz functions are used to construct sum rules. The sum rules relate the frequency dependence of the material parameters with their high-

Capacitive Circuit Method for Fast and Efficient Design of Wideband Radar Absorbers

A simple, fast and efficient method for designing wideband radar absorbers is proposed. The idea is to modify the circuit analog absorber method without perturbing the bandwidth. This is done by utilizing the asymptotic behavior of such an absorber at low frequency and replacing the band-stop resonating frequency selective surfaces with low-pass capacitive ones, which can be synthesized by square
