MODELIRANJE SLIK SAR Z AVTO-BINOMSKIM MODELOM
Marko Hebar, 2010, dissertation

Abstract: Doktorska disertacija predstavlja odpravljanje pegastega šuma z modeliranjem in izločanjem informacij iz posnetkov SAR (ang. Synthetic Aperture Radar - SAR), ki je izvedeno z Bayesovim sklepanjem. Novost, ki jo predstavljam v doktorski disertaciji je uporaba avto-binomskega modela pri Bayesovem sklepanju prvega reda, kjer ga za apriorno verjetnost uporabimo pri modeliranju posnetka. Verjetje v Bayesovem sklepanju prvega reda modelira pegasti šum, ki ga opišemo z gama porazdelitvijo. Odpravljanje pegastega šuma je izvedeno s cenilko največje verjetnosti MAP (ang. maximum a posteriori - MAP), ki jo je analitično zelo težko rešiti, zato z avto-binomskim modelom uporabimo aproksimacijo z diferencialom. Parametri avto-binomskega modela se določijo z Bayesovim sklepanjem drugega reda. Robovi v posnetku se določijo z algoritmom rasti regij. Glede na koeficient variacije so ločene homogene od heterogenih regije in adaptivno prilagajanje okolice avto binomskega modela. Eksperimentalni rezultati so pokazali, da predstavljena metoda zelo dobro modelira teksture in ima dobre lastnosti odpravljanja pegastega šuma in zelo dobro modelira teksture v realnih posnetkih SAR.

Sol-gel/Ag coating and oxygen plasma treatment effect on synthetic wound fluid sorption by non-woven cellulose material
Zdenka Peršin, Tanja Pivec, Miran Mozetič, Karin Stana-Kleinschek, 2017, short scientific article

Abstract: Non-woven cellulose material was functionalized using two techniques, i.e. the coating with AgCl via sol-gel and oxygen plasma. The treatment effects were studied regarding the wound fluid adsorption potential using physiological saline, synthetic exudate and synthetic blood. Plasma treatment was most efficient since a significant improvement by absorbency rate and capacity was evident, less pronounced in case of synthetic blood. The combination of both treatments showed a similar trend, while the effects were less prominent, but still sufficient by managing fluid-associated as well as infected wounds.
Keywords: non-woven cellulose fabric, sol-gel, oxygen plasma, absorption, synthetic wound fluids
