This paper presents analysis of object location accuracy of a mobile device on the basis of the iBeacon technology. The research starts with radio signal strength indicator analysis along the corridor in order to create a path loss model for iBeacon. Two cases are taken into account: line of sight and non-line of sight for model creation. For both cases two tests: Chi-square, Shapiro-Wilk have been...
Zamieszczono wyniki badań nanostrukturalnych powłok azotkowych nanoszonych łukowo-plazmową metodą PVD na płytki skrawające z węglików spiekanych w Instytucie Zaawansowanych Technologii Wytwarzania w Krakowie. Stosowane były powłoki na bazie azotków chromu i azotków niektórych metali, takich jak np. aluminium i tytan. Przedstawiono struktury ww. powłok, z uwzględnieniem ich wielowarstwowej budowy w...
We have estimated the number of 5S rRNA genes in Aspergillus nidulans using two-dimensional agarose gel electrophoresis and hybridization to appropriate probes, representing the 5'-halves, the 3'-halves of the 5S rRNA sequence and a sequence found at the 3'-end of all known A. nidulans pseudogenes (block C). We have found 23 5S rRNA genes, 15 pseudogenes consisting of the 5'-half of the 5S rRNA sequence...
