Opis:
The production of flint projectile points in the late stage of the Neman culture shows certain elements which are clearly similar in terms of technology and typology to the solutions known from flint-working of the people representing the Neolithic and Early Bronze Age cultures. The occurrence of such features has already been presented in relation to Neman culture ceramic production which lies at the heart of the concept of separating horizons within Linin type complexes. An in-depth analysis of the techno-typological features of flintworking in the Neman culture, and especially the typological category of projectile points, reveals similar patterns as well as cultural and chronological references in the case of ceramics. The most striking elements show analogies to those known from the south-eastern area of the cultural groupings influenced by impulses flowing from the civilization centres of the time. Traces of these influences are clear in certain typological and technological solutions, such as the forms of triangular projectile points, or in applying a trough-like retouch on such points. At the current stage of research, it is hard to determine whether the analogies observed result from not yet recognised intercultural contacts, or rather constitute a certain signum temporis characteristic of production in a wider area but during a single, specific chronological interval.

Opis:
This article discusses the most important issues regarding the implementation of digital algorithms for control and drive technology in industrial machines, especially in open mining machines. The article presents the results of tests in which the algorithm and drive control parameter settings were not selected appropriately for voltage-fed induction motors, and where the control speed was not verified by any of the available motoring or simulation methods. We then show how the results can be improved using field-oriented control algorithms and deep parameters analysis for sensorless field-oriented performance.
