Opis:
The matrix converter is a new generation of power electronic converters and is an alternative to back-to-back converters in applications that dimensions and weight are important. In this paper, a simple control algorithm for a three-phase asynchronous motor based on a direct torque control technique, which is fed through a three-phase direct matrix converter, is presented. For direct matrix converters, 27 switching modes are possible, which using the predictive control technique and for the different modes of the matrix converter, the motor behavior is estimated at the next sampling interval. Then the objective function is determined and the optimal possible mode is selected. Finally, the best switching mode is applied to the direct matrix converter. In order to evaluate the proposed method, simulation of the system in Matlab/Simulink software environment is performed. The results show the effectiveness of the proposed method.

Opis:
This article focuses on the determinants of inward foreign direct investment (FDI) in Russia. The article briefly describes the historical context of foreign investment policymaking in Russia since the beginning of the economic transition to an open market economy after the dissolution of the Soviet Union. When compared to other developing countries, Russia's FDI stocks continue to lag despite a set of proactive measures undertaken by the national government. Following the literature review, the most commonly cited determinants explaining inward FDI in Russia include market size, labour productivity, trade and investment barriers, domestic exchange rate, rule of law and institutional framework.

Opis:
Nowadays, the improvement of ferrous materials performance is a problem of high interest. One of well-known wear- and corrosion properties improving technique is plasma nitriding, in which elemental nitrogen is introduced to the surface of a metal part for subsequent diffusion into the material. As a result, a compound, “white” layer and a diffusion zone are formed at the detail’s surface. Most of the authors positively describe the effects of surface ion nitiding. On the other hand, there are also reports on adverse effects of direct current and pulsed direct current plasma nitriding on ferrous materials performance. Therefore, an attempt to provide comprehensive summary on direct current and pulsed direct current ion nitriding and its influence on ferrous materials’ mechanical and corrosion properties has been made. According to the results, some of the technique drawbacks are hard to avoid in mass production.

Opis:
The paper presents the Monotone Structural Evolution, a direct computational method of optimal control. Its distinctive feature is that the decision space undergoes gradual evolution in the course of optimization, with changing the control parameterization and the number of decision variables. These structural changes are based on an analysis of discrepancy between the current approximation of an optimal solution and the Maximum Principle conditions. Two particular implementations, with spike and flat generations are described in detail and illustrated with computational examples.

Opis:
The market of financial services, including insurance services is a subject of dynamic transformations. The core essence of insurance and their economic and social importance, has remained unchanged for a very long time. However, the circumstances of functioning of the insurance companies are constantly changing. Since the beginning of political changes in Poland, that is, since 1990, many new insurance companies have emerged on the national market. Their growing num-ber contributed to increased competition, and thus, to modification of marketing strategies em-ployed by them. These changes relate in particular to two areas. The first area is the pricing policy, while the second concerns the forms of distribution of insurance services. The intense competition for customers associated with the market penetration forces companies to reduce prices. This in turn requires searching for ways to reduce operating costs of the enterprises. One of them is the cost associated with maintaining permanent business facilities and their staff. Therefore, for sever-al years on, most companies has aimed to curb these costs. The distribution of insurance products through electronic channels is now a rapidly expanding phenomenon in Poland. Modern communication tools are not only a convenient and accessible source of information about insurance products, but they also provide the ability to compare different offers. On the other hand, they are increasingly becoming an effective tool used to sell insurance policies. This article presents the results of studies assessing the selected quality aspects of insurance companies in the opinion of customers using the Direct Purchase Insurance services.
Rynek usług finansowych, w tym usług ubezpieczeniowych, ulega dynamicznym przeobrażeniom. Sama istota ubezpieczeń oraz ich znaczenie ekonomiczne i społeczne, pozostają od lat niezmienione. Zmieniają się natomiast warunki funkcjonowania firm ubezpieczeniowych. Od początku zmian ustrojowych, czyli od 1990 roku, na rynku krajowym pojawiają się wciąż nowe firmy ubezpieczeniowe. Ich rosnąca liczba przyczyniła się do zwiększenia konkurencji, a co za tym idzie, do modyfikacji realizowanej przez nie strategii marketingowej. Jej zmiany dotyczą w szczególności dwóch obszarów. Pierwszy to polityka cenowa, drugi zaś dotyczy form dystrybucji usług ubezpieczeniowych. Intensywna rywalizacja o klienta związana z penetracją rynku wymusza na firmach obniżanie cen. To z kolei wymaga poszukiwania sposobów na ograniczenie kosztów funkcjonowania przedsiębiorstw. Jednym z nich są koszty związane z utrzymywaniem stacjonarnych placówek firmowych oraz ich personelu. Dlatego od kilku lat większość firm z branży zmierza do ograniczenia tych pozycji kosztów. Intensywnie rozwijającym się zjawiskiem w Polsce jest dystrybucja ubezpieczeń za pośrednictwem kanałów elektronicznych. Nowoczesne narzędzia komunikacji stanowią z jednej strony wygodne i dostępne źródło informacji o produk-tach ubezpieczeniowych, dają też możliwość porównywania różnych ofert. Z drugiej strony coraz częściej stają się skutecznym narzędziem wykorzystywanym do sprzedaży polis ubezpieczeniowych. Celem artykułu jest przedstawienie wyników badań dotyczących oceny wybranych aspek-tów jakości oferty firm ubezpieczeniowych w opinii klientów korzystających z usług typu „direct”.

We are here concerned with a different aspect of cancellation. We describe exact conditions on A for which it necessarily follows that A ≅ B. In the process, we do the following: Given an arbitrary digraph A and a digraph C that admits a homomorphism onto an arc, we classify all digraphs B for which A×C ≅ B×C.

Opis:
Given graphs A, B and C for which A×C ≅ B×C, it is not generally true that A ≅ B. However, it is known that A×C ≅ B×C implies A ≅ B provided that C is non-bipartite, or that there are homomorphisms from A and B to C. This note proves an additional cancellation property. We show that if B and C are bipartite, then A×C ≅ B×C implies A ≅ B if and only if no component of B admits an involution that interchanges its partite sets.

Opis:
This paper has been devoted to analyzing the implications of the economic crisis, which was triggered by the mortgage credit defaults in the United States in the summer 2007, on the flows of foreign direct investment (FDI) in the world. The issue has not been broadly studied in the economic literature and the sufficient explanation has not been delivered yet. The problem is essential due to the significant influence of the crises on reshaping the global architecture. The distinctive feature of this paper is focusing on the rising power of emerging economies as new sources of FDI in the distressed world economy. Main numerical analysis was conducted using preliminary data on FDI in year 2009 and beginning of year 2010.

The automotive industry is one of the branches with the highest degree of internationalization of production. The beginnings of the investment activities of automobile concerns, including Western Europe, in the new Member States date back to the early 1960s. The inflow of foreign direct investment to the automotive sector was widespread in the 1990s. The transition to a market economy was accompanied by growing demand for foreign capital with the change in ownership of industrial enterprises. The main form of inflow of FDI to Poland to the automotive sector, since the beginnings of the 90s was the takeover of existing industrial plants by foreign investors for their restructuring and joint ventures.

A coloring of a graph G is an acyclic coloring if the union of any two color classes induces a forest. It is proved that the acyclic chromatic number of direct product of two trees T₁ and T₂ equals min{Δ(T₁) + 1, Δ(T₂) + 1}. We also prove that the acyclic chromatic number of direct product of two complete graphs Kₘ and Kₙ is mn-m-2, where m ≥ n ≥ 4. Several bounds for the acyclic chromatic number of direct products are given and in connection to this some questions are raised.

A standard result states the direct product of two connected bipartite graphs has exactly two components. Jha, Klavžar and Zmazek proved that if one of the factors admits an automorphism that interchanges partite sets, then the components are isomorphic. They conjectured the converse to be true. We prove the converse holds if the factors are square-free. Further, we present a matrix-theoretic conjecture that, if proved, would prove the general case of the converse; if refuted, it would produce a counterexample.

Opis:
In dynamic positioning systems, nonlinear cost functions, as well as nonlinear equality and inequality constraints within optimal thrust allocation procedures cannot be handled directly by means of the solvers like industry-standardized quadratic programing (QP), at least not without appropriate linearization technique applied, which can be computationally very expensive. Thus, if optimization requirements are strict, and problem should be solved for nonlinear objective function with nonlinear equality and inequality constraints, than one should use some appropriate nonlinear optimization technique. The current state-of-the-art in nonlinear optimization for gradient-based algorithms is surely the sequential quadratic programing (SQP), both for general applications and specific thrust allocation problems. On the other hand, in recent time, one can also notice the increased applications of gradient-free optimization methods in various engineering problems. In this context, the implementation of selected derivative free direct search algorithms in optimal thrust allocation is proposed and discussed in this paper, and avenues for future research are provided.
