“…Uz to bi bilo planirano da i uređaj sadrži odgovarajuć lek za pacijenta, da u slučaju mu se desi nešto neočekivano, i hitna pomoć ne bi stigla brzo, da taj lek uspe da pomogne osobi, i čak da mu spasi život. Osim toga, u planovima budućeg razvoja aplikacije, planira se njeno integrisanje sa istraživačkim sistemom za razvoj stohastičkog elektorkardiografaelektrokardiografa koji će primeniti koncepte iz ranije razvijenih metoda digitalnog stohastičkog merenja [7][8][9][10][11][12][13][14][15].…”

“…U ovom trenutku se procenjuje da najveća preostala sistematska greška potiče od konačne rezolucije diterskog signala generisanog primenom DA konvertora. Predložena je nova metoda [5] koja daje mogućnost generisanja ditera bez primene DA konvertora. Ovaj rad se bavi softverskim simulacionim modelom namenjenim za proveru predložene metode.…”

U radu je prikazan simulacioni model nove metode za generisanje naponskog šuma uniformne raspodele vrednosti. Ovaj šum, diter, je ključni element u radu stohastičke analogno digitalne (AD) konverzije. Za razliku od uobičajenog načina generisanja primenom šift registra sa linearnom povratnom spregom (Linear Feedback Shift Register - LFSR) i digitalno analognog (DA)konvertora nova metoda je zasnovana na asinhronom odabiranju testerastog ili trougaonog napona. Kao osnovni dobitak predložene metode se navodi kontinualnost ditera po vrednosti, za razliku od prethodnog rešenja koje karakteriše diskretan diter. Primena kontinualnog ditera omogućava dalje povećanje efektivne rezolucije stohastičkog AD konvertora.

“…Knowledge of this single parameter of the medium -the speed of sound is sufficient in many practical cases. At the same time, it is evident that in many essential inverse problems it is impossible to confine oneself to this approximation and it is necessary to use more accurate models of the structure of the medium and introduce other additional parameters that allow a more adequate description of reality (Gibson, 2018;Safarov, 2018;Pejić et al, 2018). These multi-parameter models provide more complete information about the structure of the medium and are therefore of great interest.…”

Nowadays, a large number of methods for solving inverse problems arising in electrodynamics and acoustics have been developed, but the development of practical systems is necessary to combine a large number of equations that contribute to the substantiation of numerical methods for solving various multidimensional problems. Therefore, the main goal of the work is a comparative analysis of statistical methods for solving the one-dimensional inverse acoustic problem, as well as in the search for acoustic resistance. To achieve this goal, the means of description and comparison, which contributed to the identification of the characteristics of acoustic impedance, were used. Also, the finite-difference solution method, the differential circuit circulation method, and the Landweber iteration method were used. It was established that the inversion method of the difference scheme is expedient to apply in the case when additional information is known accurately enough, and the reconstructed solution is quite smooth. It was determined that if one of these conditions is violated, the method of reversing the difference scheme becomes unstable. The problems of the correctness of the issues for the wave equation with complex velocity in the one-dimensional and spatial cases were investigated. Formulas for solving these problems were obtained – analogs of classical formulas. Numerical computations show the kind of results that may be expected from the method under consideration. The materials of the paper imply the practical significance for the university teachers of the information technology specializations.
