PURPOSE The aim of this work was to implement, validate, and compare two procedures for routine image quality (IQ) assurance in dental cone-beam computed tomography (CBCT): 1. the German standard DIN 6868 - 161 introduced in 2013 and 2. the established standard IEC 61,223 - 3-5 for clinical CT x-ray equipment referenced as "DIN" and "IEC" below. MATERIALS AND METHODS The approximated in-plane...

Measurement of serum or plasma and brain cholinesterase (ChE) activities in wild birds is used to diagnose and monitor their exposure to organophosphate and carbamate insecticides (Marden et al., 1994; Burn & Leighton, 1996; Iko et al., 2002; Osten et al., 2005). Reduced enzyme activity is an indicator of exposure and adverse effects of anti ChE insecticides even in the absence of overt signs o...

Let 0= U0,n ≤ U1,n ≤ ··· ≤ Un−1,n ≤ Un,n = 1 be an ordered sample from uniform [0,1] distribution, and Din = Ui,n −Ui−1,n, i = 1,2, . . . ,n; n = 1,2, . . . , be their spacings, and let f1n, . . . , fnn be a set of measurable functions. In this paper, the probabilities of the moderate and Cramer-type large deviation theorems for statistics Rn(D)= f1n(nD1n) + ···+ fnn(nDnn) are proved. Applicati...

Obiectivul acestei lucrări constă în dezvoltarea şi implementarea unui regulator digital PID pentru convertoarele statice. Sunt studiate prin simulare şi experimentări efectele factorilor KP, KI şi KD asupra răspunsului buclei de reglare. În partea a doua a lucrării, este prezentată o analiză comparativă experimentală a două convertoare (un redresor comandat realizat din tiristoare cu filtru ca...

Teoria mulţimilor Rough s-a dovedit a fi o tehnică utilă în analiza datelor incomplete. Fundamentele acesteia au fost îmbunătăţite de-a lungul timpului, iar aplicaţiile se referă la variate domenii, putând fi considerată complementară altor teorii care lucrează cu date incomplete, cum ar fi inferenţa Bayeziană sau teoria mulţimilor fuzzy. Articolul prezintă câteva concepte din teoria mulţimilor...

[1] To assess the effects of increased atmospheric N input on N availability in ombrotrophic peatlands, the relative concentrations of dissolved organic nitrogen (DON) to dissolved inorganic nitrogen (DIN) were measured in bog waters along a natural gradient of atmospheric N deposition. Six European bogs were selected, spanning a range of chronic atmospheric N inputs from 0.2 to 2.0 g m 2 yr . ...
