In general, traditional evaluations of target camouflage effects are usually conducted based on observational data and general results of statistical analysis. This widely applied methodology quantifies the detection and identification probabilities of camouflage objects but has considerable shortcomings. This data evaluation process is laborious and time-consuming and very low in reproducibility, which sheds light on the necessity of developing a more efficient method in this study field. The growth of computeraided image processing technology provides technical support for camouflage effect evaluation based on digital image processing. Digital pattern painting, which has been previously applied to combat utility uniforms, is a new methodology full of potential due to its broad geographical adaptability. This study proposes a multi-scale pattern-in-picture method to evaluate camouflage effects at different distances. We also established a computer-aided background image library and camouflage assessments with digital simulation and created an evaluation system that could be effectively applied to combat utility uniforms. More than 40 testers participated in this study, who were asked to score the designed camouflage schemes using the evaluation system proposed. The data from simulation assessments and individual evaluations show that the computer-aided simulation assessments conducted as part of this research can efficiently and objectively evaluate the camouflage effect on military objects.

Celem artykułu jest przedstawienie problemów, jakie się pojawiają przy projektowaniu stropów gęstożebrowych w przypadku ich modelowania i analizy przy użyciu metod komputerowych. Autorzy proponują różne sposoby uwzględnienia specyficznego charakteru pracy tych ustrojów w programie opartym na metodzie elementów skończonych. Omówiono sposób poprawnej interpretacji uzyskanych rezultatów i ich zastosowania inżynierskiego. Wskazano dodatkowe zalety opisanego sposobu projektowania w porównaniu z klasycznymi obliczeniami.

The aim of the article is to present the problems related to designing suspended beam and block floor systems, especially when modelling and analyzing them with the use of computer methods. The authors suggest different ways of taking into account the specific nature of these structures in a program based on a finite element method (FEM). They discuss the way in which obtained results can be interpreted correctly and used for engineering applications. They also indicate additional advantages resulting from the described design method in comparison to traditional calculations.

Wybór strategii eksploatacji systemów SRK ma znaczący wpływ na bezpieczeństwo i koszty eksploatacji urządzeń. Obecnie stosowana strategia wg resursu jest mało opłacalna ekonomicznie. Ponadto strategia ta nie uwzględnia przyspieszonego zużycia, co może pogorszyć bezpieczeństwo systemu. Wprowadzenie proponowanej strategii wg stanu technicznego wymaga ciągłej rejestracji parametrów eksploatowanego systemu. W rozdziale 2 przedstawiono projektowany system akwizycji danych.

Choosing strategies for systems SRK has a significant impact on safety and the operating costs. Currently, the strategy used by TBO is hardly economically viable. Moreover, this strategy does not take into account accelerated wear, which may compromise system security. The introduction of the strategy proposed by the state technical parameters requires continuous registration system operated. Chapter 2 presents designed data acquisition system.
