  Monitoring of dioxygen levels is of utmost importance from the view-point of life processes, medical diagnostics, nutrition and chemical industries. In all these measurements both low and high levels of this element are important. The common methods for the determination of dioxygen are the Winkler method, Clark electrode and pulsoxymeters. A new, already strong field of research can be now recognized – the development of miniaturized...

  We consider two-parameter bifurcation of equilibrium states of an elastic rod on a deformable foundation. Our main theorem shows that bifurcation occurs if and only if the linearization of our problem has nontrivial solutions. In fact our proof, based on the concept of the Brouwer degree, gives more, namely that from each bifurcation point there branches off a continuum of solutions.

• Uniform Model Interface for Assurance Case Integration with System Models

  Publication

  - Year 2017

  Assurance cases are developed and maintained in parallel with corresponding system models and therefore need to reference each other. Managing the correctness and consistency of interrelated safety argument and system models is essential for system dependability and is a nontrivial task. The model interface presented in this paper enables a uniform process of establishing and managing assurance case references to various types...

  In this work, we address an everlasting issue in 2 model order reduction (MOR) in electromagnetics that has 3 remained unnoticed until now. Contrary to what has been 4 previously done, we identify for the very first time spurious 5 modes in MOR for time-harmonic Maxwell’s equations and 6 propose a methodology to remove their negative influence on the 7 reduced order model (ROM) response. These spurious modes 8 have nonzero resonance...

  Porównano technikę HPLC i klasyczną metodę spektrofotometryczną Winklera pod względem odzysku, precyzji, wykrywalności i oznaczalności 5-hydroksymetylofurfuralu (HMF) w miodach naturalnych. Zawartości HMF obiema metodami oznaczono w 15 różnych miodach naturalnych. Sześć miodów pochodziło z trójmiejskich punktów handlowych, 9 miodów pozyskano bezpośrednio od pszczelarzy z sześciu pasiek. Testem t-Studenta oszacowano istotność różnic...
