The article discusses the book Roizman. The Ural Robin Hood by Valery Panyushkin (2014). The author of the article points out that the novel, which belongs to a non-fiction literature, contains typical features of a reportage (i.e. the category of a participant and the category of a witness). This book also seems to be taking qualities of a narrative prose. The writer uses virtual reported speech form or presents reality from the perspective of his characters’ awareness. Such a narrative method does not lead Panyushkin to blur the boundary between referentiality and fi ctionality in his book but inclines cognitive skepticism. Neither does it neglect the “truth” of facts, nor does it interpret them, but it indicates various ways of interpreting certain events or phenomena.

Mesoscale flows of liquid are of great importance for various nano- and biotechnology applications. Continuum model do not properly capture the physical phenomena related to the diffusion effects, such as Brownian motion. Molecular approach on the other hand, is computationally too expensive to provide information relevant for engineering applications. Hence, the need for a mesoscale approach is apparent. In recent years many mesoscale models have been developed, particularly to study flows of gas. However, mesoscale behaviour of liquid substantially differs from that of gas. This paper presents a numerical study of micro-liquids phenomena by a Voronoi Dissipative Particle Dynamics method. The method has its origin from the material science field and is one of very few numerical techniques which can describe correctly molecular diffusion processes in mesoscale liquids. This paper proves that correct prediction of molecular diffusion effects plays predominant role on the correct prediction of behaviour of immersed structures in the mesoscopic flow.

ARGUMENTUM

Heroinas et heroas, quos mala fortuna in tragoediis Graecis persequitur, aliae personae scenicae commiserantur, aliae autem spernunt et irrident. Narratur hic, quomodo tales animi passiones quarundam tragoediarum actionem afficiant.

The paper concerns the problem of state assignment for finite state machines (FSM), targeting at PAL-based CPLDs implementations. Presented in the paper approach is dedicated to state encoding of fast automata. The main idea is to determine the number of logic levels of the transition function before the state encoding process, and keep the constraints during the process. The number of implicants of every single transition function must be known while assigning states, so elements of two level minimization based on Primary and Secondary Merging Conditions are implemented in the algorithm. The method is based on code length extraction if necessary. In one of the most basic stages of the logic synthesis of sequential devices, the elements referring to constraints of PAL-based CPLDs are taken into account.

The aim of the paper is to present the implementation of a PLC designed in the form of a System-on-a-Chip. The presented PLC is compatible with the IEC61131‒3 standard. More precisely, the Instruction List language is the native language of the designed CPU, so there is no need for multiple language transformations. In the proposed solution each instruction of the CPU program written in Instruction List is directly translated to machine code. The designed CPU is capable of performing logic operations up to 32-bit Boolean data types. However, the developed CPU is very flexible due to its architecture: data memory can be addressed as bit/byte/word/dword. Moreover, diverse blocks such as timers, counters, and hardware acceleration blocks, can be connected to the CPU by means of an APB AMBA bus. The designed PLC has been implemented in an FPGA device and can be used in cyber-physical systems and Industry 4.0.
