An Innovative Approach to the Forecasting of Energetic Effects While Wood Sawing
PublicationIn the classical approach, energetic effects (cutting forces and cutting power) of wood sawing process are generally calculated on the basis of the specifi c cutting resistance, which is in the case of wood cutting the function of more or less important factors. On the other hand, the cutting forces (power) problem may be tackled with an innovative, up-to-date fundamental analysis of the mechanics of sawing based on modern fracture mechanics....

Revisiting the estimation of cutting power with different energetic methods while sawing soft and hard woods on the circular sawing machine: a Central European case
PublicationIn the classical approaches, used in Central Europe in practice, cutting forces and cutting power in sawing processes of timber are commonly computed by means of the specific cutting resistance kc. It needs to be highlighted that accessible sources in handbooks and the scientific literature do not provide any data about wood provenance, nor about cutting conditions, in which cutting resistance has been empirically determined. In...

Zagrożenie katastrofą budowlaną Mostu Uniwersyteckiego w Bydgoszczy. Analiza i badania
PublicationMost Uniwersytecki został zamknięty po 7 latach od oddania do użytku. Powodem były błędy projektowe ujawnione w przeglądzie w roku 2020, potwierdzone teoretycznymi analizami nośności. Bezpośrednim powodem zamknięcia przeprawy było stwierdzenie zagrożenia katastrofą budowlaną. W roku 2021, zgodnie z zaleceniem i koncepcją ekspercką, krytyczne elementy konstrukcji mostu zostały wzmocnione. W styczniu 2022 most został przywrócony...

Crystal structure and electronic structure of CePt2In7
PublicationWe report a corrected crystal structure for the CePt2In7 superconductor, refined from single crystal x-ray diffraction data. The corrected crystal structure shows a different Pt–In stacking along the c-direction in this layered material than was previously reported. In addition, all of the atomic sites are fully occupied with no evidence of atom site mixing, resolving a discrepancy between the observed high resistivity ratio of...

Support for argument structures review and assessment
PublicationArgument structures are commonly used to develop and present cases for safety, security and for other properties of systems. Such structures tend to grow excessively, which causes problems with their review and assessment. Two issues are of particular interest: (1) systematic and explicit assessment of the compelling power of an argument, and (2) communication of the result of such an assessment to relevant recipients. The paper...
