Thermal and mechanical piston influence on photoacoustic signal
(Istočno Sarajevo : Elektrotehnički fakultet, 2023)
In this work, the influence of the thermal and mechanical piston effects over the frequency at which the amplitudes of the components of the photoacoustic signal resulting from these two effects are equalized. The analysis ...
Mathematical modeling of anomalous diffusive behavior in transdermal drug-delivery including time-delayed flux concept
(Chaos, Solitons & Fractals, 2023)
Molecular transport through a composite multilayer membrane is a central process in transdermal drug delivery (TDD). Classical Fickean approach treats skin as a pseudo-homogenous membrane, while in reality skin is highly ...
Photoacoustic Characterization of TiO2 Thin-Films Deposited on Silicon Substrate Using Neural Networks
(Materials, 2023)
In this paper, the possibility of determining the thermal, elastic and geometric characteristics of a thin TiO2 film deposited on a silicon substrate, with a thickness of 30 μm, in the frequency range of 20 to 20 kHz with ...
Thermal characterization of n-type silicon based on an electro-acoustic analogy
(Journal of Applied Physics, 2023)
Based on the analogy between resistor-capacitor (RC) filters and the thermoelastic component of a photoacoustic signal, the complex thermoelastic response of an open photoacoustic cell is described as a simple linear ...
Ispitivanje uticaja nanetog sloja boje na površinske temperaturske varijacije laserski sinterovanog poliamida / Investigation of the influence of the applied dye layer on surface temperature variations of laser sintered polyamide
(Istočno Sarajevo : Elektrotehnički fakultet, 2022)
U ovom radu ispitivan je uticaj nanetog sloja boje na površinske temperaturske varijacije uzorka poliamida. Uzorak, dobijen laserskim sinterovanjem industrijskog praha PA2200, se obasjava mnodulisanim laserskim snopom, dok ...
Data Analysis of Impaired Renal and Cardiac Function Using a Combination of Standard Classifiers
(Journal of Personalized Medicine, 2023)
We examine the significance of the predictive potential of EPI cystatin C (EPI CysC) in combination with NTproBNP, sodium, and potassium in the evaluation of renal function in patients with cardiorenal syndrome using ...
Effects of nanosecond laser pulses at 248 nm wavelength on multilayer CrN/(Cr,V)N coatings
(Belgrade : Institute of Physics Belgrade, 2017)
The effects of UV nanosecond laser pulses on multilayer CrN/(Cr,V)N coatings were studied. In the experiment laser irradiation was performed in air at 248 nm wavelength and pulse duration of 25 ns. The surface composition ...
Photoacoustic response of a transmission photoacoustic configuration for twolayer samples with thermal memory
(Belgrade : Institute of Physics Belgrade, 2017)
Over the last thirty years, multilayered systems have increasingly drawn attention due to their growing appearance in both natural and artificial structures. A number of measurements require the adsorption of an electrically ...
Influence of the protective layer on the photoacoustic response of transparent samples
(Belgrade : Institute of Physics Belgrade, 2021)
In the transmision photoacoustic measurements of transparent samples, using minimum volume cell configuration, a thin protective layer is applied on one surface of the examined samples in order to protect the microphone. ...
On the applicability of the effective medium approximation to the photoacoustic responses of multilayered structures
