The article presents experiments in realistic modelling of facial expressions using volume morphing. The experiments use a variable number of points and face features. As the results are shown meshes deviations (between goal mesh and morphed shape). Experiments have shown that it is impossible to carry out a fully realistic morphing based on existing software. At the same time, even imperfect morphing allows you to show the expected emotional facial expression.

Obowiązujące w Polsce Prawo geologiczne i górnicze nie reguluje w sposób zadawalający zabezpieczenia środków finansowych na likwidację kopalń i rekultywację terenów pogórniczych. Sukcesywne gromadzenie środków na koncie funduszu likwidacji zakładu górniczego nie zapewnia pokrycia kosztów w przypadku wcześniejszej przed wyczerpaniem zasobów złoża konieczności zakończenia eksploatacji. W przepisach określających obowiązki przedsiębiorcy eksploatujących złoża kopaliny na podstawie koncesji udzielanej przez starostę, brakuje konkretnych rozwiązań dotyczących sposobu zabezpieczenia środków finansowych na likwidację kopalni.

Dla rozwiązania tego problemu proponuje się wprowadzić sposób szacowania kosztów likwidacji kopalni wykorzystujący wskaźniki kosztów odniesione do jednostki zasobów operatywnych złoża bądź do jednostki powierzchni zajmowanej pod działalność wydobywczą. Oszacowane koszty likwidacji powinny być wnoszone na konto w banku (podobnie jak w przypadku kopalń tworzących fundusz likwidacji zakładu górniczego). Zaleca się, aby wnoszone one były jednorazowo i w całości, a wyjątkowo w dwóch ratach i stanowiły zabezpieczenie wykonania likwidacji kopalni.

Uzupełnienie obowiązującego systemu prawno-finansowego likwidacji kopalń o proponowane rozwiązanie wymagać będzie nowelizacji przepisów Prawa geologicznego i górniczego oraz przygotowania informacyjno-organizacyjnego tego przedsięwzięcia.

This paper presents a method intended for calculation of steady-state processes in AC/AC three-phase converters that are described by nonstationary periodical differential equations. The method is based on the extension of nonstationary differential equations and the use of Galerkin's method. The results of calculations are presented in the form of a double Fourier series. As an example, a three-phase matrix-reactance frequency converter (MRFC) with boost topology is considered and the results of computation are compared with a numerical method.

The purpose of this paper is to present and analyse the decision-making problem faced by a future house owner - selection of the optimal solution of building thermal insulation in relation to the selected criteria, both related to costs and future benefits. The problem of selecting the best solutions in the construction sector is widely discussed in the science literature. In this paper, the authors decided to solve the raised problem by using the Entropy method.

The Author comments on a new book by Mariusz Mazur O człowieku tendencyjnym... — a book on the communist endeavour to create a new man. He considers the book excellent. Its important positive point is the analysis of the theme in a large framework of human history. Communism was a very singular regime but the idea of a new man appeared several times through centirues and in different countries.

This year we are celebrating 150 anniversary of the discovery of DNA by Friedrich Miescher. His finding initiated a series of discoveries that allowed to depicts life's most famous molecule with novel features with considerable biological interest. In this article we recall the biggest mile stones of 150-year history of DNA and present the context and meaning of several key observations that have brought us closer to understanding DNA. 150 years ago, people had no idea that DNA existed, and they certainly hadn’t heard of DNA structure and sequencing. We now know that DNA is a dynamic, tortuous coil, constantly shuffling and unwinding. Today DNA is all around us, in a physical sense and in a cultural sense. It is really part of our culture. We will discuss also the little known facts, often overlooked in similar discussions. We will focus particularly on Professor Richard Altmann's from Iława, whose contribution to knowledge about nucleic acids is significant, although not well recognized so far.

The article shows that during the forming of grammatical category of gender in Indo-European languages, names of non-living objects and names of those animals whose sex is unimportant for humans were receiving grammatical meanings of gender on the basis of similarity or dissimilarity of designated objects with males or females. Such grammatical metaphors were based on the ideas of different peoples about some minor characteristics of persons of different sex, such as the difference between men and women with higher activity, greater size, strength and independence. By now, the metaphorical motivation of category of gender in the Russian language has survived only in certain nouns. These nouns are interrogative pronouns кто (masc.) ʻwhoʼ and что (neut.) ʻwhatʼ, paired nouns-synonyms, e. g. конь (masc.) ʻstrong horseʼ – лошадь (fem.) ʻordinary horseʼ, generic versions of nouns, e. g. ворон (masc.) ʻravenʼ – ворона (fem.) ʻcrowʼ, and nouns-occasionalisms used in speech oriented to expressiveness and creativity.
