On some open questions for Ramsey and Folkman numbers
PublicationWe discuss some of our favorite open questions about Ramsey numbers and a related problem on edge Folkman numbers. For the classical two-color Ramsey numbers, we first focus on constructive bounds for the difference between consecutive Ramsey numbers. We present the history of progress on the Ramsey number R(5,5) and discuss the conjecture that it is equal to 43.

Using Continuous Integration Techniques in Open Source Projects – An Exploratory Study
PublicationFor a growing number of software projects, continuous integration (CI) techniques are becoming an essential part of the process. However, the maturity of their adoption in open source projects varies. In this paper, we present an empirical study on GitHub repositories to explore the use of continuous integration techniques in open source projects. Following the Goal-Question-Metric (GQM) approach, 3 research questions and 7 metrics...

Data Acquisition in a Manoeuver Auto-negotiation System
PublicationTypical approach to collision avoidance systems with artificial intelligence support is that such systems assume a central communication and management point (such as e.g. VTS station), usually located on shore. This approach is, however, not applicable in case of an open water encounter. Thus, recently a new approach towards collision avoidance has been proposed, assuming that all ships in the encounter, either restricted or open...

Vacuum Rabi oscillation in nonzero-temperature open cavity
PublicationPorównania teorii oscylacji Rabiego z eksperymentem [M. Wilczewski, M. Czachor, Phys. Rev. A 79, 0333836 (2009)] sugerują, że parametry wnęki doświadczeniu z dużą ilością fotonów mogą być znacznie mniejsze niż te otrzymane dla stanów prawie próżniowych. W tym kontekście pokazujemy, że wniosek pozostaje bez zmian, nawet jeśli do opisu stanu początkowego wnęki zastosuje się bardziej realistyczny opis.
