Opis:

The monitoring of the environmental components condition, exposed to the influence of the cement production enterprises, was the aim of the conducted research. One of the largest cement production factories in Russia, where the territory of negative impact has a total area of over 300 square kilometers, was the object of the study. The observations of the dust content in atmospheric air, as well as the determination of degradation degree of vegetation in the area of influence of the considered production facility were conducted. Chemical and granulometric composition of the cement dust, which is emitted in atmospheric air, were identified in the laboratory. Mapping model, which indicates the complex ecological welfare of the territory, exposed to the cement production industry, was compiled by the authors on the basis of the data, obtained in conducted research. The mapping model takes into account both the content of dust in near-ground atmosphere, and the extent of its deposition to soil, vegetation and surface water bodies.

Opis:

In order to limit dust transfer during the operations of material transportation at the factories of the construction industry, factories of the mineral and raw materials complex employ special dust suppression bunkers. These devices are structures located above a railway hopper (either a truck body or a conveyor). Through the input portal of the device, the transported material is transferred. Dusting can also be carried out under the bunkers from the side of the hopper, into which the material is poured. The design of dust suppression bins should be accompanied by a simulation of dust propagation processes. The simulation should be carried out in order to minimize the dust emissions and to select the optimum locations for the dust suppression sprayers.

Opis:

The construction of subway stations is inevitably accompanied by the formation of a large amount of waste that is extracted from the underground workings by rock. When the waste is transported, the air is polluted with the exhaust gases of the dump trucks, some of the waste can stay on the road surface, the use of dump trucks increases the load on the roadway, the disposal of waste at landfills harms the environment, and enterprises pay fees for the transportation as well as placement of the waste. The article deals with the waste from the construction of new stations in the Saint-Petersburg subway. In order to determine the possibility of using waste in the municipal economy, a comprehensive analysis of this waste was carried out, including determination of moisture content, acidity, total carbon content, as well as chemical and granulometric composition. On the basis of the study results, it was established that the waste in question belongs to the hazard class 5, which enables to use it as a component of the soil mixture. Afterwards, the hazard class 5 was confirmed by the method of bioassay based on the determination of water toxicity by changing the optical density of the Chlorella algae culture.

Opis:

Organization of effective management of municipal waste is a complex management task, characterized by a multiplicity and heterogeneity of the factors that must be taken into account, and multistage associated with different content process applicable at each stage. To make effective management decisions we must to decide the problem of the availability of reliable and timely information. The geo-information system for monitoring and waste management can be seen as a higher-order system element, including for complex socio-eco-economic assessment of the status of the region. The main task of achieving economic efficiency of waste sorting is: "It must be economically profitable for population and management companies to sort waste and dispose them in different containers." To do this, the tariff for the export of unsorted waste containers should be maximized and the cost of removal of sorted waste should be minimal (ideally - zero). The results obtained have allowed significantly improve the capacity and effectiveness of the decisions made, in particular, on issues such as the optimization of traffic flows, division of human settlements into separate areas on a territorial basis and a reasonable preparation of technical tasks in the organization of tender procedures in the management system of sanitary clearing settlements.
Organizacja efektywnego zarządzania odpadami komunalnymi jest złożonym zadaniem, które charakteryzuje się wielością i różnorodnością czynników, które muszą być brane pod uwagę. Jest to wieloetapowy proces związany z różnymi procesami technologicznymi mającymi zastosowanie na po-szczególnych etapach. Problem dostępności wiarygodnej i aktualnej informacji jest wspólny dla wszystkich etapów podejmowania skutecznych decyzji w zakresie obchodzenia się z twardymi odpadami komunalnymi. Geoinformacyjne systemy monitorowania i zarządzania odpadami mogą być postrzegane jako element wyższego rzędu systemowego, również dla kompleksowej oceny społeczno-ekologicznego i gospodarczego statusu regionu. Głównym zadaniem osiągnięcia efektywności ekonomicznej segregacji odpadów jest: „Ludność i spółki zarządzające, które muszą mieć korzyść z sortowania odpadów i wyrzucania ich do różnych pojemników”. Aby to zrobić, taryfy na wywóz nieposortowanych pojemników na odpady powinny być zmaksymalizowane, koszt usuwania odpadów segregowanych powinien być minimalnym (idealnie – zero). Otrzymane wyniki wskazują na znaczne poprawienie skuteczności podejmowanych decyzji szczególnie w takich kwestiach jak optymalizacja ruchu transportowego, podział na osobne obszary terytorium mieszkaniowego, bardziej uzasadnione przygotowania zadań technicznych w organizacji proce-dur przetargowych w systemie zarządzania sanitarnych oczyszczeń zamieszkałych obszarów.

The ground-state energy and the number of the phonons are calculated as functions of the parameters of the Hamiltonian. The renormalizations of the phonon frequency and electron hopping for bonding and antibonding states are considered. The destruction of quasiclassical mean field solution is discussed.

The main goal of the presented work was to study the behavior of the lithium CPS in the condition simulating the influence of plasma in various operating regimes of the thermonuclear reactor. The tests were conducted in a Plasma Focus (PF) installation. The preliminary analysis of the received results confirms the high resistance of the lithium CPS to the pulse influence of plasma flows.

Optical absorption measurements were exploited to study periodic InN:In structures grown by plasma-assisted molecular beam epitaxy with the thickness of the metallic inclusions varied from 2 to 48 monolayers. We demonstrate that the observed higher-energy shift of an effective absorption edge may be due to In depletion of the InN matrix via the coalescence of In into large clusters, accompanied by the respective higher-energy shift of the Mie resonance. The relevant uncertainty in the optical gap of InN is discussed.

Experimental investigations were performed to evaluate the focusing properties of the plasma focus for high-energy intense ion beams manipulating. Magnetic probes and optical spectroscopy were used for temporal and spatial plasma geometry investigations. Ion beam portrait was determined at the luminescence screen. In the experiments performed, the focusing coefficient was obtained as the ten times beam compression at the 30 cm length. By variations of the gas volume input, gun voltage, time delay, magnetic field value etc. the dependence of focused ion beam diameter upon various parameters of the plasma focus lens has been investigated. It was revealed that the main focusing effect was caused by the azimuthal magnetic field of the currents carried by the plasma.

Using such an approach, we reconsider the two-dimensional electron gas with the Rashba spin-orbit interaction and show that impurity scattering processes suppress the spin Hall effect.

A comparative analysis of several methods of interpretation of solvent influence on molar Kerr constants of solutes was done. The analysis was based on experimentally determined electro-optical and dielectric properties of binary solutions of organic substances with various polarities, polarizabilities and optical anisotropies. It was found that the role of universal van-der-Waals interactions treated via London-Debye-Keesom potentials was best accounted for by a modified orientational theory of Kerr effect that developed the ansatz of reactive field and local dielectric permittivity. An extrapolation method of determination of gas phase molar Kerr constants of solutes was deduced from the theory.

Opis:

The Dense Plasma Focus (DPF) devices PF-1000, PF-6 and PF-5M working with different gases and in dissimilar irradiation modes were used to carry out experimental investigations of irradiation of a number of materials by powerful pulsed ion and high-temperature plasma streams. The materials under test were designed for application in structural and functional components of thermonuclear fusion devices with magnetic (MPC) and inertial (IPC) plasma confinement, as well as for working chambers of plasma and accelerator devices. The main features of the materials are low-activation and radiation-resistant properties. On the basis of the investigations a significant progress was achieved in understanding of dynamics of high-energy nano- and micro-second pulsed streams in DPF from one side as well as on the mechanisms of their influence upon materials under irradiation from the other one. We demonstrated that this approach can be useful for certain tests of plasma-facing materials (e.g. W for MPC and stainless steels for IPC) and of structural (construction) elements of the above-mentioned devices subjected to pulsed high-energy radiation streams. The results obtained suggest also that DPF devices can be used in new pulse technologies for material treatment by means of powerful nanosecond and microsecond pulses of plasma and ion streams.

Opis:

Zirconia-based bulk glasses were prepared for the first time by sol-gel method. Such materials are very promising for application as photochromic devices, catalytic systems, chemical sensors, lasers and other nonlinear optics devices. Obtained transparent and semi-transparent materials were studied by small and ultra-small angle neutron scattering (SANS and USANS) methods. As evidenced by SANS, morphology of zirconia glasses is very sensitive to parameters of sol-gel synthesis, e.g. temperature and concentration of reactants. SANS data correlates rather well with surface porosity data. Increasing water concentration in reaction mixtures containing zirconium propylate leads to a significant increase in fractal cluster size, while decrease of the temperature results in an increase of the fractal dimension. The obtained results indicate that parameters of the microstructure and consequently physical properties of zirconia glasses can be effectively controlled by parameters of synthesis.

Opis:

The electronic structure of the ternary RAgSn (R=Ce,Pr,Nd,Dy) compounds which crystallize in the hexagonal LiGaGe-type structure was studied by X-ray photoemission spectroscopy. Core-levels and valence bands were investigated. The X-ray photoemission spectroscopy valence bands are compared with the ones calculated using the spin-polarized tight-binding linear muffin-tin orbital method. The obtained results indicate that the valence bands are mainly determined by the Ag 4d band. The spin-orbit splitting values Δ$\text{}_{SO}$ determined from the XPS spectra of 3d$\text{}_{5}\text{}_{/}\text{}_{2}$ and 3d$\text{}_{3}\text{}_{/}\text{}_{2}$ are equal to 18.8eV for R= Ce, 20.2eV for R = Pr and 22.6eV for R = Nd. The analysis of these spectra on the basis of the Gunnarsson-Schönhammer model gives a hybridization of f orbitals with the conduction band. The calculation of the total energy for two models of the crystal structure: an ordered of the LiGaGe-type and a disordered one of the CaIn$\text{}_{2}$-type indicate that in these compounds the LiGaGe-type structure is stable. Additionally, the temperature dependences of the electrical resistivity of CeAgSn and DyAgSn are investigated. At high temperatures the resistivity is not a linear function of temperature which indicates an electron-phonon interaction in the presence of a small s-d scattering, whereas at low temperatures anomalies connected with the magnetic phase transitions are observed.

We report on molecular beam epitaxy of InSb insertions in InAs and InAsSb matrices, emitting at wavelengths beyond 4μm. Different growth techniques for deposition of InSb quantum dots in the 1-2 monolayer range of the InSb nominal thickness, namely conventional molecular beam epitaxy and migration enhanced epitaxy, as well as different matrices (InAs and InAsSb) have been employed for increasing the emission wavelength of the InSb/InAs nanostructures. The formation of InSb quantum dots has been studied in situ using reflection high energy electron diffraction and ex situ by using transmission electron microscopy. The peculiarities of In(Ga)AsSb alloys growth and compositional control are also discussed. Bright photoluminescence up to 4.5μm has been observed at 80 K.

Opis:

The isolated teeth of a new euselachian shark Artiodus prominens Ivanov and Duffin gen. et sp. nov. have been found in the Artinskian Stage (Early Permian) of Krasnoufimskie Klyuchiki quarry (Sverdlovsk Region, Middle Urals, Russia). The teeth of Artiodus possess a multicuspid orthodont crown with from four to nine triangular cusps; prominent labial projection terminating in a large round tubercle; distinct ornamentation from straight or recurved cristae; oval or semilunar, elongate, considerably vascularized base; dense vascular network formed of transverse horizontal, ascending, short secondary and semicircular canals. The teeth of the new taxon otherwise most closely resemble the teeth of some protacrodontid and sphenacanthid euselachians possessing a protacrodont-type crown, but differ from the teeth of all other known euselachians in the unique structure of the labial projection. The studied teeth vary in crown and base morphology, and three tooth morphotypes can be distinguished in the collection reflecting a moderate degree of linear gradient monognathic heterodonty. The range of morphologies otherwise displayed by the collection of teeth shows the greatest similarity to that described for the dentitions of relatively high-crowned hybodontids from the Mesozoic. The internal structure of the teeth, including their vascularization system is reconstructed using microtomography. The highest chondrichthyan taxonomic diversity is found in the Artinskian, especially from the localities of the Middle and South Urals.

The report describes some of the results obtained in an experimental study of the impact of a powerful plasma stream and a fast ion beam generated in a PF-1000 device on different materials perspective for the use in radiation loaded parts of pulsed plasma installations. Investigations were done during and after the interaction processes. It is shown that in case of irradiation of samples only by high power flux density plasma streams the effect of detachment still preserved. At the same time a low power flux density high-energy ion beam plays an important role in the process of saturation of the irradiated material by hydrogen.

Opis:

The paper presents various designs of several medium and small size Dense Plasma Focus (DPF) chambers intended for numerous applications, a description of technologies used in these facilities, and some results reached with these devices by using a number of diagnostic techniques. In present experiments the DP foci have been used mainly as an X-ray source. We discuss here how it is possible to satisfy absolutely new and very strict demands on the construction and technology for the devices to be eventually applied in science and industry. Between these characteristics there are a high repetition rate (typically 1…15 Hz) and a long lifetime (over 1 million shots). Their switching elements, a collector and chambers must withstand a high quasi-continuous heat load (up to 100 kW). High energy density in the central part of the chamber anode and the necessity to provide a channel for radiation extraction demanded a special construction and specific materials implementation in this region. Their X-ray spectrum should be tuned. They have to operate with different working gases and preferably in a wide range of pressures. All these points are discussed in this report. Capabilities of the described techniques are illustrated by results of the recent experimental studies carried out with facilities located at the Nanyang Technological University (NX1) as well as at the Lebedev Physical Institute (PF-0.2).

The Mn 2p core-level spectra for both compounds were ascribed to the relevant Mn sites in their crystal structure. The valence band spectra were compared with the result of ab-initio band calculations using the tight-binding linear muffin-tin orbital method. It was concluded that the enhancement of the spectral density within the 2 eV binding energy region below the Fermi energy comes from the effect of strongly correlated Mn 3d electrons.

Opis:

Very rare chondrichthyan spines from the Famennian (Upper Devonian) of European Russia are referred here to ctenacanthiforms, euselachians and a chondrichthyan group of uncertain systematic position. Ctenacanthus Agassiz, 1837 is recorded from the lower and middle Famennian of the central and north-western parts of the area. Sculptospina makhlaevi Lebedev gen. et sp. nov. originates from the lower Famennian of the Lipetsk Region. The holotype of ‘Ctenacanthus’ jaekeli Gross, 1933 and a new specimen from the upper Famennian of the South Urals are shown to belong to the same taxon, which is transferred to Acondylacanthus St. John and Worthen, 1875. New specimens of Tuberospina nataliae Lebedev, 1995 from the upper Famennian of Central Russia are described in detail. The newly presented material increases our knowledge of the composition of Famennian marine assemblages from the East European Platform. It is suggested that these assemblages may be classified as chondrichthyan-dominated and dipnoan-dominated. Hypothetically, after the end- Devonian Hangenberg extinction event, which affected numerous secondary consumers in vertebrate communities, some chondrichthyan groups could have encroached to take advantage of previously occupied ecological niches. Ctenacanthus, as well as Acondylacanthus and Amelacanthus survived the end-Devonian mass extinction to continue into the Carboniferous.

Such laser system can have widespread applications in medicine as laser scalpels with regulated cutting depth. We further demonstrate a stimulated emission under Cr2+ to 1+ photo-ionization pumping. The latter opens chances for laser emission under carrier injection conditions.

Opis:

The procedure of the qualitative analysis of complex technical systems is discussed. One may use such methods of analysis for time series characterized the functioning of such systems. These time serious aren’t confirmed the hypothesis of trend existence. One may use at this qualitative analysis the methods of nonlinear dynamics and the theory of chaos. The basis for similar researches is Takens’s theorem. The randomness of the studied dynamical system as the model of the complex technical system given by time realizations is established by means of Lyapunov’s indicator. The state stability is estimated by Hausdorf’s fractal dimension and the fractality index. Visual evaluation of the time series was carried out by means of the phase trajectory restoration procedure. As a result of the analysis of the phase points in the phase space the split attractor is indicated, which gives the chance to speak about its bifurcation.

Jak wynika z doświadczenia światowego, efektywną metodą stworzenia, wdrożenia i kontroli przedsiębiorczości jest system Balanced Scorecard (BSC) - Zrównoważony System Wskaźników rozwoju firmy. Celem niniejszej publikacji jest rozpatrzenie istoty i znaczenia tego systemu w strategicznym zarządzaniu przedsiębiorstwem oraz analiza zalet nowego podejścia, jako narzędzia w stymulowaniu pracy personelu. Należy zauważyć, że w specjalistycznej terminologii krajowej często używana jest nieprawidłowa definicja "Zrównoważona Karta Wyników". Stosowanie terminu "wynik" zamiast "wskaźnik" jest według autorów nie do przyjęcia, ponieważ wynik oznacza końcowy rezultat działalności, natomiast stosowanie BSC oznacza strategię zarządzania w celu osiągnięcia przyszłych wyników. Również bezpośrednie tłumaczenie słowa "Card" w oderwaniu od "Scorecard" jest typowym błędem, ponieważ w obróbce danych całe to słowo tłumaczy się, jako "System Wskaźników". Aby uniknąć niepotrzebnych rozbieżności w terminologii autorzy zostają przy definicji "Zrównoważony System Wskaźników", stosując przy tym angielski skrót BSC.
An effective method of creation, adaptation and control of entrepreneur-ship is the Balanced Scorecard (BSC) of a company development. The (BSC) is semi-standard structured report supported by proven design methods and automation tools. It can be used by managers to keep track of the execution of activities by staff within -their control and monitor the consequences arising from these actions. It is perhaps the best known of several such frameworks, and was widely adopted in the world. The concept of the BSC is based on forming a company development strategy and its subsequent realization with consideration of the current results of the key directions of the company's activities. In practice, it is a strategic performance management tool and mechanism of consistent understanding by the personnel of the strategic goals of the company and of the controls of their achievement through the so called Key Performance Indicator (KPI). Those indicators are the measure of the goals' achievability and, also, the characteristics of the business processes and of the work of each individual employee. The core characteristic of the BSC and its derivatives is the presentation of a mixture of financial and non-financial measures each compared to a 'target' value within a single concise report. The report is not meant to be a replacement for traditional financial or operational reports, rather a succinct summary that captures the information most relevant to those reading it. It is the methods by which this 'most relevant' information is determined (i.e. the design processes used to select the content) that most differentiates the various versions of the tool in circulation. This ideology has been known for a long time and an opinion is widespread that there is no need of developing any new strategies of management. It is enough to study the existing models of strategy that are widely known and described in literature (Table 1). By using those strategies, one is able to create their own that is the most appropriate for the particular conditions of activity. The BSI system has four projections, each of which is associated with the key questions of functioning of the company. The answers to those questions are the objectives, the achievement of which will be the evidence of progress on the way to realization of the whole strategy of development (Table 2). Mutual dependencies must be established between those projections as well as the order of realization of the key directions of the company's activity. An example of the objective development scheme for particular projections is depicted in Drawing 1. Certain methods and tricks have been developed within the BSI for the purpose of effective solution of those questions. First of all, the BSI methodology has convenient and graphic tool -the Strategic Map. This Map describes the cause-effect relations between the strategic goals according to the key development prospects: finances, clients, business processes and personnel (Table 3). The other important tool of the BSI is the Strategic Topic. It is the consolidated group of identical goals and indicators of the activity effectiveness. Such combination of indicators allows making the strategy more understandable and accessible.

Anti-Stokes luminescence is observed in chromium doped and in undoped ZnSe crystals. In the former case anti-Stokes luminescence is due to two complementary ionization transitions of Cr ions. In the latter case two-photon absorption becomes important at a high excitation density.

Opis:

Role of deep impurity levels in carrier generation, transport, and recombination were investigated in bulk ZnSe:Cr and ZnTe:V:Al crystals by four-wave mixing technique. The temporal and exposure dependencies of optical nonlinearities in ZnSe:Cr evidenced an influence of Cr1+/Cr2+ states in carrier generation, exhibited very fast carrier relaxation, and revealed the presence of competing recombination mechanisms. Similar investigations in ZnTe:V:Al showed an effective carrier generation from Al-induced defect complexes as well as very fast carrier capture by Zn-vacancies.

Opis:

Photoluminescence transitions in (CdTe,CdCrTe)/CdMgTe structure grown by molecular beam epitaxy are studied. Photoluminescence investigations show a very strong reduction of the photoluminescence intensity from chromium doped quantum wells. We explain this fact by a very efficient nonradiative recombination in the chromium-doped quantum wells. The present results indicate that the Auger-type energy transfer from excitons to chromium ions is responsible for the photoluminescence deactivation. The efficiency of this process is evaluated.

Opis:

The influence of addition of Zn on band parameters of Zn$\text{}_{x}$Cd$\text{}_{y}$Hg$\text{}_{1-x-y}$Te solid solution at different temperatures (4.2-200 K) was investigated. The cyclotron resonance at 4.2 K and magnetophonon resonance at 77-200 K were used to determine band structure parameters. The temperature dependence of band structure parameters (energy gap, effective mass of electron) for the composition of series of epilayers (x varied in 0.08-0.20 range and y - 0.07-0.12) was obtained. It is found that band structure parameters for some compositions (for example x = 0.17, y = 0.08) are almost independent from temperature and equal: γ₁$\text{}^{L}$= 19.55, γ₂$\text{}^{L}$ = γ₃$\text{}^{L}$ = 8.5, K$\text{}^{L}$ = 6.48, F = -0.5, E$\text{}_{g}$ = 0.35 eV, E$\text{}_{p}$ = 17.9 eV. The effective mass of electrons was found to be greater with addition of Zn while the effective mass of heavy holes is left unchanged.

Opis:

The results of experimental investigations of powerful hydrogen plasma jets and fast ion beams interaction with various materials (austenitic chromium-manganese steels, pure vanadium, tungsten, graphite, copper, and their alloys: Cu-4 mass% Ni and Cu-10 mass% Ga) are presented. The materials were placed on the discharge axis of the PF-1000 device and irradiated with fluxes of fast ions (of energy in the range from tens keV up to several MeV) and with plasma streams (of power flux density q~(108 109) W/cm2). It was found that the fast ions and plasma streams caused different damages to the aforementioned materials. A diverse character of the damages to the individual investigated material was revealed. Some peculiarities of the process as well as the correlation between the surface density of the "macroscopic" structural defects (blisters and craters) and the fluence of the fast ions implanted in the specimen are discussed.

Opis:

Changes in the optical characteristics in synthetic sapphire specimens produced by microsecond pulse irradiation with a stream of hydrogen ions of energies ranging up to tens keV have been observed. Data on decrease in the optical reflection, measured within the wavelength range of 200 900 nm, are presented. This characterization is compared with the data received by optical and atomic force microscopy as well as by lattice structure analysis performed with X-rays. The measurements indicate that the changes of optical parameters are not a consequence of absorption increase and/or sapphire decomposition. They result from modifications of the morphology and structure of surface layer of the sapphire samples, induced by irradiation.

Opis:

Energy up-conversion in chromium and iron doped ZnSe results in the appearance of an anti-Stokes luminescence. The process is efficient in ZnSe:Cr, but not in ZnSe:Fe. We conclude that very efficient three-center Auger processes in ZnSe:Fe quench the anti-Stokes luminescence emission. For chromium doped samples influence of the Auger mechanism is weaker, which we explain by less efficient carrier retrapping by Cr ions. We further discuss possibility of efficient pumping of infrared Cr-related emissions via Cr photoionization transition.

It is demonstrated that a fast component of the photoluminescence decay, reported previously for quantum dot structure and related to quantum confinement effects, is also observed in bulk samples and is related by us to very efficient spin cross-relaxation effects.

Prior to the growth Si substrate was annealed at 1300-1400°C in propane. The so-prepared substrate is covered with a thin (≈ 4 nm) SiC wafer, which allowed a successful growth of good morphological quality cubic phase GaN epilayers. The present results confirm recent suggestion on smaller ionization energies of acceptors in cubic phase GaN epilayers.

Opis:

A review of results on the design and operation of the new efficient Dense Plasma Focus device PF-6 of medium size (transportable) having bank energy of ca. 7 kJ and possessing a long lifetime is presented. New data on the interaction of the pulsed fast ion beams and dense plasma streams generated at this apparatus with various materials are given. These results are compared with the analogous information received at the biggest facility PF-1000. It is shown that it is possible to have about the same power flux density (in the range of 105 109 W/cm2) in both devices however in different areas. Doses of soft X-rays produced by the device within the resists for the goals of microlithography and micromachining appear to be several times less that it is with the conventional X-ray tube. In biological application of this device, medium- and hard-energy X-rays are exploited in the field of radioenzymology. It was found that the necessary dose producing activation/inactivation of enzymes can be by several orders of magnitude lower if used at a high-power flux density in comparison with those received with isotope sources. In medicine, short-life isotope production for the goals of the positron emission tomography (medicine diagnostics) is possible by means of the fast ions generated within DPF. All these experiments are discussed in the framework of pulsed radiation physics and chemistry in its perfect sense thereto the criteria are formulated.

Opis:

The paper discusses an approach to the question of the possibility of a mathematical description of discrete processes. On the basis of these processes a large class of manufacturing equipment – production lines and systems for the processing of fish was generated. The use of mathematical models in the early stages of the design will improve the efficiency and quality of the produced equipment and reduce the risks and costs during the design work. We propose to describe the processes of fish processing by topological models that are presented in the form of functional graphs. Overall, the proposed approach will develop new design methods of fish processing equipment.
W pracy omówiono podejście do kwestii możliwości matematycznego opisu dyskretnych procesów. Na podstawie tych procesów tworzona jest szeroka gama urządzeń przemysłowych - linie produkcyjne i systemy do przetwarzania ryb. Wykorzystanie modeli matematycznych we wczesnych etapach tworzenia może poprawić wydajność i jakość wytwarzanych maszyn i zmniejszenia ryzyka oraz koszty podczas prac projektowych. Zaproponowano opis procesów przetwórstwa ryb z wykorzystaniem modeli topologicznych, które są prezentowane w postaci wykresów funkcjonalnych. Ogólnie rzecz biorąc, proponowane podejście umożliwi opracowanie nowych metod projektowania urządzeń przetwórstwa rybnego.
