The authors present the optimisation procedure and results, applied to the system discussed in part I. This procedure utilises a "fixed variables" method from the group of "search methods". The optimisation is related to the specific turbocharged engine STAR T3 70 for which necessary construction data and experimental measurements were available. Calculation results, however, are based mainly on the computer simulation of time dependant flows in the inlet and exhaust systems of this engine. They show that the presented method, after necessary improvements and the use of more advanced optimisation procedures, could represent an additional and attractive tool, which might be used by designers of such systems.

The subject of the article is the occurrence of dialectal features in Internet nicknames. The analysis was carried out on the basis of about 2500 nicknames that contained dialectal features. The names were obtained within the years 2012–2015. In the analysis, linguistic areas were indicated in which we may notice the influence of local dialects on that layer of the Internet anthroponymy. The influence of local dialects is visible in the fact that the Internet users reach for traditional folk names as well as name models related to the folk manner of identifying a human being, e.g. Jagatka, Jantecek, Janielka od Genowefy, Cesiek z Tuchowa. Apart from references to folk anthroponymy, the Internet nicknames reflect the influence of local dialect lexis (e.g. gzub, graślok, fusyt), phonetics (janioł, Carownica, łokrutny łoptymista), inflection (Śpisok z Łapsóf, ciupaga łod tater) and word-formation, e.g. (rzemyszek, cwaniuk).
