En nutida gesällvandring - Utlandspraktik vid sex svenska industrigymnasier

Svenskar har under en längre tid besökt internationella kunskapscentra. Redan under medeltiden började hantverkare att göra gesällvandringar på kontinenten och senare reste ingenjörer till ledande industriländer. Dessa grupper kom tillbaka med nya kunskaper som bidrog till att Sverige inte bara kunde hänga med i den teknologiska utvecklingen utan också under perioder tillhöra de ledande länderna.

Another look at the exact bit error probability for Viterbi decoding of convolutional codes

In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 (2-state) convolutional encoder with generator matrix G(D)=(1 1+D) when used to communicate over the binary symmetric channel. Their method was later extended to the rate R=1/2, memory m=2 (4-state) generator matrix G(D)=(1+D^2 1+D+D^2) by Lentmaier et al. In this paper,

Ca-Pd/Pt-Ge Compounds on the Zintl Border

Zintl compounds form a category in intermetallic chemistry somewhere between metallic and ionic compounds. Classical Zintl compounds form between electropositive and electronegative elements, such as the alkaline earth metals and the p-block elements, i.e. elements with a relatively large electronegativity difference. The concept is based on the idea of a complete charge transfer from the electro
