Abstract

An original method for time delay estimation is presented. It is based on changing input signals into cumulative ones, followed by determination of inflection points of cumulative curves, and estimation of time delay as time difference of these points’ occurrences. To determine the inflection points, a suitable algorithm is proposed. The preliminary results show that the proposed method is sufficiently efficient, especially in the case of flow measurements based on tomography technique when the cross-correlation function of the signals has no evident peak. This method has no limitations on its application for different types of input signals.

Abstract

Studies were conducted using a 10-chamber Micro-Oxymax (Columbus, OH, USA) respirometer to determine the effect of bioaugmentation, biostimulation and combination of them on enhancing intrinsic biodegradation of oil hydrocarbons in soil. Contaminated soil was collected from a former military airport in Kluczewo, Poland. Bioaugmentation was realized by addition of indigenous or exogenous bacteria to soil. Biostimulation was done by aerated water supply and surfactant addition. Bioaugmentation + addition of a surfactant was applied as the combined treatment. The intrinsic and enhanced hydrocarbons biodegradation rates were estimated from the slopes of linear regressions of cumulative curves of O2 uptake. Pertinent biodegradation rates were recalculated on the basis of the stoichiometric reaction (mass balance equation) and conversion equation. The results showed that combined treatment (indigenous bacteria bioaugmentation + addition of a surfactant) was the most effective method of biodegradation enhancement as the 20-fold increase of biodegradation rate was observed.

diagram ( Fig. 7 ) we can conclude that the samples taken from the cone are better sorted, because their transport path was theoretically the longest. This relationship can be weakly seen in the samples taken from the upper and middle parts of the valleys.

system, shows a distinct inten- sity increase in the duration sector 10.5 —• 24 hours, caused by intensive rain-inducing mechanisms of the cold front. The problem of classification of rainfall events according to the genetic types is important in the study aimed at design hyetograph development. Temporal distribution of rainfall intensity is closely related to the genetic type of the events. The temporal patterns of rainfall intensity were obtained on the basis of rainfall episodes classified into the genetic types. Dimension- less cumulative curves of rainfall
