METHOD FOR SHIP'S ROLLING PERIOD PREDICTION WITH REGARD TO NON-LINEARITY OF GZ CURVE
PublicationThe paper deals with the problem of prediction of the rolling period. A special emphasis is put on the practical application of the new method for rolling period prediction with regard to non-linearity of the GZ curve. The one degree-of-freedom rolling equation is applied with using the non-linear stiffness moment and linear damping moment formulas. A number of ships are considered to research the discrepancies between the pending...

Experimental evaluation of estimator mean square error curve for cognitive tracking radar
PublicationTo make decisions, cognitive radar must rely on predictions of its own performance. In the literature, these predictions are usually based on some form of Cram\'er-Rao lower bound. This approach is scientifically sound, but it also brings a possibility of the cognitive controller overestimating radar performance. It therefore makes sense to back theoretical predictions with careful experiments which will verify their applicability....

Influence of nitrogen and organic matter fractions on wastewater treatment in treatment wetland
PublicationMunicipal wastewater contains both biodegradable and non-degradable pollutants. Moreover, they are present in dissolved, colloidal and particulate forms. These fractions are characterised by various decomposition rates, hence their bioavailability during microbial respiration. It was confirm that biological degradation rate in terms of COD reduction is influenced by particle size speciation. Therefore, the objective of the study...

Organic matter removal efficiency in treatment wetlands simulation by COD fractions
PublicationThe objective of this paper was to investigate the organic fraction (colloidal, particulate, and dissolved) in sewage treatment in treatment wetland. Performance of TWs was simulated well with a simple first order model k – C* based on monitoring data. In this investigation background or residual concentration (C*) was assumed to be equal concentration of input influent organic matter in particulate (CODp). Calculated reaction...

Evaluation of VSC Impact on Power System Using Adequate P-Q Capability Curve
PublicationRenewable energy sources, which are becoming increasingly popular, often use a voltage source converter (VSC) for connection to the power system. Assessing the effects of connecting such a source to the power system is essential to ensure the proper operation of the power system and the connected source. For this purpose, it is necessary to know the range of active and reactive power generation by the converter. The authors indicate...

Insulin-like growth factor type 2 is better than insulin-like growth factor type 1 a survival marker in patients after acute decompensation of heart failure
PublicationIntroduction:A decreased IGF-1 has been found in heart failure (HF). There are no reports assessing IGF-2 in HF, although in vitro study has shown, that IGF-2 stimulates cardiomyocyte proliferation more than IGF-1. The study aim was to compare the IGF-1 and IGF-2 concentration depending on HF exacerbation and annual survival.Material and methods:Among 75 patients hospitalized...

Dependence between quality and removal effectiveness of organic matter in hybrid constructed wetlands
PublicationW procesie oczyszczania ścieków w Vertical Flow Constructed Wetland (VF-CW) jednym z czynników jest dopływ tlenu. Niewystarczający dopływ tlenu do złoża może być przyczyną braku efektywności usuwania zanieczyszczeń, a więc wskazywać na niewłaściwą eksploatację obiektu.Obiekty badań stanowiły złoża pionowe stanowiące jeden z elementów biologicznego oczyszczania dwóch hybrydowych systemów hydrofitowych zlokalizowanych w Wieszynie...

Influence of COD-fractions on removal effectiveness and accumulation of organic matter in constructed wetlands
PublicationW pracy wykazano, że efektywność usuwania substancji organicznej doprowadzanej w ściekach bytowo-gospodarczych do złóż hydrofitowych zależy od rodzaju frakcji substancji organicznej oraz ich stężeń. Na podstawie analizy poszczególnych frakcji ChZT (rozpuszczonych związków organicznych biologicznie łatwo- i nierozkładalnych oraz zawiesin organicznych biologicznie wolno- i nierozkładalnych) wykazano, że na akumulację substancji organicznej...
