Assessment of the Impact of GNSS Processing Strategies on the Long-Term Parameters of 20 Years IWV Time Series
PublikacjaAdvanced processing of collected global navigation satellite systems (GNSS) observations allows for the estimation of zenith tropospheric delay (ZTD), which in turn can be converted to the integrated water vapour (IWV). The proper estimation of GNSS IWV can be affected by the adopted GNSS processing strategy. To verify which of its elements cause deterioration and which improve the estimated GNSS IWV, we conducted eight reprocessings...

Inhibition effect of free ammonia on deammonification process under different intermittent aeration strategies in sequencing batch reactor
PublikacjaThe deammonification process involves two steps. The first step is the partial nitrification of ammonia (NH4-N) by ammonia oxidizing bacteria (AOB) to produce nitrite (NO2-N) and the second step is the anammox process to “anaerobically” oxidize ammonia to nitrogen gas with nitrite as an electron acceptor (Lackner et al., 2014). Free ammonia (FA) plays a significant role in the stable, long-term deammonification system operation....

On minimum cost edge searching
PublikacjaWe consider the problem of finding edge search strategies of minimum cost. The cost of a search strategy is the sum of searchers used in the clearing steps of the search. One of the natural questions is whether it is possible to find a search strategy that minimizes both the cost and the number of searchers used to clear a given graph G. We call such a strategy ideal. We prove, by an example, that ideal search strategies do not...
