Walsh analysis - a convenient preprocessor for period detection in astronomy
(Astronomical Observatory Belgrade, 2016)
Walsh analysis is practically analogous to Fourier analysis, except that square wave is used instead of the sine one. It has one major advantage over Fourier - it can be performed much faster. This may seem of little ...
Antioksidativna aktivnost etanolnih ekstrakata Thymus serpyllum
(Faculty of Technology, Zvornik, 2015)
Wild Thyme (Thymus serpyllum, Lamiaceae) is a subshrub from the Lamiaceae family, with
plants that are rich in essential oils and antioxidative polyphenolic substances. Reducing
potential of phenolic compounds gives them ...
Quantitative structure – property relationship studies of liquid chromatography – mass spectrometry responsiveness of aripiprazole and its impurities using artificial neural networks
(Université de LilleFaculté de Pharmecie de Lille, 2018)
The importance of studying electrospray ionization (ESI) technique stems from its widespread liquid
chromatography – mass spectrometry (LC-MS) character, particularly emphasized in scientific areas with most
of non-volatile ...
Micromechanical investigating of the critical parameter's influence on adhesive properties of porous EVA/PMMA polymer blends using finite element method
(Belgrade : Institute of Technical Sciences of SASA, 2016)
Mechanical properties of two Al-Mg alloys manufactured by accumulative roll bonding (ARB) process
(Belgrade : Association of Metallurgical Engineers of Serbia (AMES), 2017)
The influence of alloying on the mechanical properties of AA5083 type Al-Mg
alloy sheets produced by accumulative roll bonding (ARB) process was studied.
Two investigated Al-Mg alloys: commercial AA5083 alloy with 4.2% ...
The influence of the cationic softeners on the structural and mechanical properties of differently pretreated cotton/elastane single jersey knitted fabrics / Uticaj katjonskog omekšivača na strukturna i mehanička svojstva različito pripremljenih pamuk/elastan desno-levih pletiva
(Beograd : Visoka tekstilna strukovna škola za dizajn, tehnologiju i menadžment, 2014)
In this study the effect of elastane and cationic softener finishing on properties of cotton and cotton/elastane single jersey knitted fabrics were studied, Samples od 100% cotton, elastane yarns in alternating courses ...
Long-term and low-temperature annealing of as-continuous drive friction welded and post-weld heat treated Al/Cu bimetal joints
(Kiev, Ukraine, 2017)
In general, continuous drive friction welding (CDFW) of two metals
may produce three typical regions from a weld interface towards an unaf-
fected base metal: (i) fully deformed or dynamically recrystallized (DRX) ...
The effects of aging on the precipitation of the W-rich phase in the matrix of the 92.5W-5Ni-2,5Fe powder metallurgy heavy alloys
(Association of Metallurgical Engineers of Serbia (AMES), Beograd, 2013)
The precipitation behavior of W-rich phase on the specific matrix locations of
Co-free and Co-containing 92.5W-5Ni-2.5Fe heavy alloys is investigated during
aging of the as-quenched samples. The aging treatment is ...
Assessment of Safety Valve Springs Failure
(Materials Research Society of Serbia, Srbija, 2011)
The aim was to investigate the cause of failure of as-received ultra-high strength steel springs,
which were deposite-coated. The qualitative analysis of surrounding environment was performed.
Springs were visually and ...
CORROSION BEHAVIOUR OF AN Al-Zn-Mg-Cu ALLOY AFTER DIFFERENT HEAT TREATMENTS
(Technical faculty Mihajlo Pupin, Zrenjanin, University of Novi Sad, Srbija, 2012)
The variation of factors such as the amount of alloying elements in solid solution, thermal and
thermo-mechanical treatments changes the corrosion tendency in the Al-Zn-Mg-Cu alloy. The measurements of
electrical ...
