In line with the requirements of circular economy, European Union’s waste management legislative changes also concern treatment sewage sludge. Although sludge production cannot be prevented, its quantities may reduced by synergetic effect energy recovery via choosing a proper technology. Sewage is difficult to apply as fuel alone, because high moisture and ash content. However, use will increased adding suitable materials (different types plastics, tires paper rejects). Most recently,...
The paper presents reliability analysis which was realized for an industrial company.The aim of the is to present usage discrete time Markov chains and flow in network approach.Discrete a well-known method stochastic modelling describes issue.The suitable many systems occurring practice where we can easily distinguish various amount states.Markov are used describe transitions between states process.The process described as graph network.The maximal corresponds production.The Ford-Fulkerson...
Fracture surfaces of X70 steel DWTT broken samples are analyzed using statistical methods and fractal concepts. Besides geometry concept the new approach based on normal vectors analysis is presented. The fracture surface covered by a triangle net. For every vector determined. Fractal dimension significantly correlated to angular deviation neighboring vectors. mean value angles lower for ductile than brittle areas. k-means cluster multivariate probability distribution applied determine local...
BACKGROUND Indication of oral appliances for the treatment an obstructive sleep apnea (OSA) includes both patients with primary snoring and mild OSA, as well moderate to severe OSA who refuse other or in whom such failed. The aim this study was verify effectiveness current by objective measurements, assess means a questionnaire patients' satisfaction manufactured our laboratory. MATERIAL AND METHODS enrolled 58 adult (40 men, 18 women) mean age 50.5 years; most were overweight had class I...
Fracture surfaces of X70 steel DWTT broken samples are analyzed using statistical methods and fractal concept. A new approach for identifying the fracture is presented. To distinguish surface area deviations between normal vectors two neighbouring elementary triangles has been evaluated. The distribution angular deviation can be described as a Gaussian mixture or lognormal distribution. mixtures parameters obtained well-known EM algorithm. Calculated map brittle probability highly...
This study describes the statistical analysis of peak forces industrial washing machines. The data source comes from twelve different measurements are done using a force gauge installed in places for fastening screws. A new software based on LabView has been developed to acting forces. To determine extreme values, various probability distributions applied. Furthermore, convex combination lognormal distribution is used more complicated cases. parameters mixtures determined modified an...
