Opis:: The emergence of globalization processes and transnational market integration has become a more and more challenging issue for scientific research in many fields, also and in particular within management science. Against this background the paper presents conceptualizations of globalizing networks based on theories and approaches such Global Commodity Chains, Global Value Chains and Global Production Networks. In particular, the paper aims to conceptualize and discuss globalizing networks with a specific focus on foreign direct investments (FDI) and special economic zones (SEZs). The article is based on heuristic approach and in-depth literature study. The text has been prepared based on heuristic approach and literature studies and it can make a small contribution to the conceptualization within in management science theory.
Postępująca globalizacja w połączeniu z wzrastającymi zjawiskami sieciowania stają się coraz większym wyzwaniem dla badań naukowych w wielu dziedzinach. W niniejszym artykule przedstawiono konceptualizację globalizujących się sieci opartą na teorii, Global Commodity Chains, Global Value Chains and Global Production Networks. Celem artykułu jest przyczynek do konceptualizacji tych zjawisk i kontynuacja dyskusji naukowej na temat roli globalizacji sieci w globalnym środowisku gospodarczym. Ponadto artykuł odwołuje się do znaczenia FDI oraz specjalnych stref ekonomicznych w procesie globalizacji sieci produkcyjnych. Tekst został opracowany na podstawie podejść heurystycznych oraz studiów literaturowych.

Opis:: 1. Introduction. It is well known that methods of algebraic geometry and, in particular, Riemann surface techniques are well suited for the solution of nonlinear integrable equations. For instance, for nonlinear evolution equations, so called 'finite gap' solutions have been found by the help of these methods. In 1989 Korotkin [9] succeeded in applying these techniques to the Ernst equation, which is equivalent to Einstein's vacuum equation for axisymmetric stationary fields. But, the Ernst equation is not an evolution equation and, due to this fact, one is in this case usually confronted with boundary value problems which have not been considered there. On the other hand, Neugebauer and Meinel [10] were able to transform the boundary value problem for the rigidly rotating disk of dust into a scalar Riemann-Hilbert problem on a hyperelliptic Riemann surface and gave the solution to this problem in terms of theta functions. The methods they used were suited to the particular problem and one may ask to which extent algebro-geometric methods are useful for the solution of boundary value problems of the Ernst equation. In order to tackle this problem one should at first develop the Riemann-Hilbert technique on Riemann surfaces in detail and then apply this method in order to find solutions to the Ernst equation. The first of these two papers is devoted to the brief introduction into Riemann surface techniques (for a more detailed exposition see the cited literature). The second paper shows how the developed methods apply to the Ernst equation.

Opis:: The article discusses the role of the modern approach to the design of autonomous utility vehicles. The study has been exemplified by a currently designed multi-purpose hybrid engineer vehicle. The article covers the application of modern hybrid drive and the suspension allowing for the regulation of the tension wheel. The drive system used in the described vehicle is a serial type. In contrast to the conventional solutions used so far in a similar vehicle, this system eliminate heavy and difficult parts to produce (e.g., gears) which allows to significant reduction of a vehicle's weight. The suspension system is based on the classical concept - with a torsional shafts. A movable tension wheel is an innovative element, which has been used in this suspension system. When the wheel is in the lower position the area of pressure increased so the force exerted on the ground is less. This option is useful in difficult, muddy off-road conditions. The Volvo Company wants to apply similar capabilities in their prototype diggers. In the article, the importance of the external appearance of the vehicle has been considered as well. A removable cab allows the remote control of the vehicle at any time and the same has been provided as an example of a modern solution concerning the external appearance of the vehicle.
