Opis:
A Wiener system, i.e. a cascade system consisting of a linear dynamic subsystem and a nonlinear memoryless subsystem is identified. The a priori information is nonparametric, i.e. neither the functional form of the nonlinear characteristic nor the order of the dynamic part are known. Both the input signal and the disturbance are Gaussian white random processes. Recursive algorithms to estimate the nonlinear characteristic are proposed and their convergence is shown. Results of numerical simulation are also given. A known algorithm recovering the impulse response of the dynamic part is presented in a recursive form.

Opis:
Niniejszy artykuł przedstawia analizę identyfikacji przestrzennej, traktowanej jako proces utożsamiania się jednostki z przestrzenią przez przyjęcie roli mieszkańca określonego terytorium, jak również poczucie łączności ze zbiorowością terytorialną stanowiącą dla jednostki społeczną grupę odniesienia. Przedmiotem analizy są zatem dwa wymiary identyfikacji przestrzennej: identyfikacja indywidualna i kolektywna (zbiorowa). Wynikiem przeprowadzonej analizy jest odpowiedz´ na pytanie, jaki jest zakres spójności przestrzennych odniesień mieszkańców Łodzi. W tym celu utworzono typologię uwzględniającą wskazane aspekty identyfikacji przestrzennej. Uzyskane wyniki prezentują, iż wśród badanych dominuje kategoria uwzględniająca proces utożsamiania się z miastem w wymiarze indywidualnym i traktowaniem zbiorowości sąsiedzkiej jako grupy odniesienia. Należy zatem stwierdzić brak spójności pomiędzy wymiarem indywidualnym i kolektywnym identyfikacji przestrzenne mieszkańców Łodzi.
The paper deals with the analysis of spatial identification treated as the process of individual identification with the particular space by taking the role of the inhabitant of the particular territory as well as the sense of the connection with the territorial community which makes the social group of positive reference for the individual. The paper analyses two measures of spatial identification: individual identification and collective one. The analyse results in answering the question what is the range of coherence of spatial references of Lodz inhabitants. In order to do that the typology including indicated aspects of spatial identification was created. Obtained results present that within investigated individuals category including the process of identification with the city in individual measure and treating the neighbour community as the reference group dominates. That is why it is necessary to notice the lack of the coherence between individual and collective measure of spatial identification of Lodz inhabitants.

Chinese is a tonal language, which differentiates it from non-tonal languages in the Western countries. A Chinese character consists of an initial, a final, and a tone. In the present study, the effects of noise and reverberation on the Chinese syllable, initial, final, and tone identification in rooms were investigated by using simulated binaural impulse responses through auralization method. The results show that the syllable identification score is the lowest, the tone identification score is the highest, and the initial iden- tification scores are lower than those of the final identification under the same reverberation time and signal-to-noise ratio condition. The Chinese syllable, initial, and final identification scores increase with the increase of signal-to-noise ratio and decrease of the reverberation time. The noise and reverberation have insignificant effects on the Chinese tone identification scores under most room acoustical environ- ments. The statistical relationship between the Chinese syllable articulation and phoneme articulation had been experimentally proved under different noise and reverberation conditions in simulated rooms.

Opis:
It has been experimentally verified that most commonly used subspace methods for identification of linear state-space systems with exogenous inputs may, in certain experimental conditions, run into ill-conditioning and lead to ambiguous results. An analysis of the critical situations has lead us to propose a new algorithmic structure which could be used either to test difficult cases and/or to implement a suitable combination of new and old algorithms presented in the literature to help fixing the problem.

The paper presents new approach to estimation of the coefficients of an elementary bilinear time series model (EB). Until now, a lot of authors have considered different identifiability conditions for EB models which implicated different identifiability ranges for the model coefficient. However, all of these ranges have a common feature namely they are significantly narrower than the stability range of the EB model. This paper proposes a simple but efficient solution which makes an estimation of the EB model coefficient possible within its entire stability range.

Opis:
The nature and effects of party identification in post-communist democracies have been an object of disputes, as the existing research does not lead to conclusive results. The present paper contributes to the discussion with analyses of four-fold typology of partisans (Rose, Mishler 1998), who either have a positive or negative party identification, or both, or none. We embed this typology in a contemporary Polish context. Using the PNES data for the 2005–2019 elections, we examine the proportions of each type of partisanship and their stability in time. We also verify what their determinants are and what their influence on electoral participation is. Our results demonstrate that positive and negative party identifications are of rational origin, although since 2015, expressive partisanship is also developing. We also prove that positive, negative, and combined motivations make Poles more prone to vote, contributing to the stability of democracy on a behavioral level.

The ability of identification of meat types using ultrasonic measurement was evaluated in this work. Four types of muscles were analyzed (turkey breast and thigh, and pork loin and ham). Ultrasonic measurements were performed at storage (5 ±1oC) and room (20±1oC) temperatures using the through-transmission technique and differential method of determination of sound velocity and the attenuation coefficient. The mean values of sound velocity for the breast, thigh, loin and ham were respectively: 1550.7, 1536.6, 1558.7, 1559.7 m/s at the storage temperature, and 1582.7, 1578.5, 1596.9, 1592.7 m/s at the room temperature. The mean values of the attenuation coefficient in the same order were: 21.3, 23.2, 30.6, 28.1 m-1 and 22.2, 18.9, 22.0, 22.4 m-1. Statistically significant differences in the sound velocity were observed between pork and turkey muscles, therefore, the meat of those species can be identified based on ultrasound measurements of sound velocity. The attenuation coefficient cannot be applied in the identification of meat types due to absence of significant differences in the mean values.

Opis:
Damage detection and identification is one of the most important tasks of proper operation of technical objects and structures. It is, therefore, essential to develop efficient and sensitive methods of early damage detection. Delamination is the type of damage occurring in laminated composites that is one of the most dangerous and most difficult to detect. In this paper, the computational study was performed on the numerical data of the modal shapes of laminated composite beams with simulated delaminations in order to detect them using a fractal dimension-based approach. The obtained results allowed for improvement of detection accuracy as compared to previously applied wavelet-based approach. An additional benefit was decreasing the computational time. Basing on the obtained results it is reasonable to consider the presented approach as a promising alternative to currently applied signal processing methods used for supporting nondestructive testing of structures.

Opis:
DNA identification, which counts a few decades only, has revolutionized forensic science. Over a short period of time, genetic identification has become the most effective method of human identification, even when a tiny amount of biological material is available. Its dynamic development has allowed shifting efforts from group to individual identification. DNA analysis is broadly used for identification of criminal offenders, and due to computer-based DNA data bases – also allows detection of offenders internationally. The technique is fundamental in identification of disaster victims and also historically – in identification of bone remains. Furthermore, it is very useful in verification of wrongful convictions. In civil litigation, DNA analysis is irreplaceable in cases involving paternity testing. Genetic identification has quite solid scientific foundations and therefore, it has dethroned fingerprint identification, being earlier recognized as the “golden” standard of human identification. What is more, DNA analysis triggered the wave of criticism towards the majority of forensic methods of identification, which are considered to be characteristic by a high level of subjectivity, and which started the process of scientific development of these methods.

This paper presents the possibility of the parametric identification of an unknown low energy explosive basing only on its ballistic curve using advanced optimisation algorithm. What was under investigation here was the approach of an explosive replication for the numerical investigation of ANSYS AUTODYN solver. The emphasis was given here for the propellants used in the automotive safety devices. The results of closed bomb testing was compared with its numerical representation. The required parameters to develop a new numerical model of an explosive was identified with the aid of evolutionary algorithm. In order to perform a parametric identification a mathematical model of considered phenomenon is required. Hence, this paper contains a mathematical model of a deflagration process which was the basis for the evolutionary algorithm. The algorithm verified a variety of parameters until the objective function is obtained. In the case of this paper the objective function was a ballistic curve of an unknown explosive which combust under deflagration regime. The results obtained with this method shows good agreement with the closed bomb test of the propellant. Furthermore, advanced optimisation tools such as an evolutionary algorithms, in oppose to most of other optimisations algorithms, enables to find a global optimum. However, the identified function here was found to be unimodal.

The module applies strong and weak constraints (lexical, morpho-syntactic, and semantic) to automatically identify coreference relations between referential expressions. We evaluate the results obtained by RefGen from a public reports corpus and we discuss the importance of the genre-dependent parameters to improve the reference chains identification.

Opis:
Extension of the method of analog circuit parameter identification for the specified design performances, originally presented by the same author in 1982, is described. These parameters are designated by means of PSpice simulation of the adjoint circuit to the original one. In this adjoint circuit, elements of the original circuit, described by the sized parameters, are replaced by controlled sources. Each such source is controlled by the differential voltage or current, difference between the calculated voltage or current and the specified one, with infinitely large gain. The method is applicable to both linear and nonlinear DC circuits and AC circuits and can be used in many fields of analog circuit design, such as: finding of acceptability region, analog fault diagnosis, postproduction identification and tuning. In the later cases, design performances are replaced by measurements of Circuit Under Test (CUT). Simplicity, extremely low computational complexity and high accuracy are the main benefits of the proposed, basic Circuit Theory based, approach - the solution is found after a single PSpice simulation. For better understanding of the presented methodology, five practical examples are discussed.

Opis:
Over the last few years, kernel adaptive filters have gained in importance as the kernel trick started to be used in classic linear adaptive filters in order to address various regression and time-series prediction issues in nonlinear environments.In this paper, we study a recursive method for identifying finite impulse response (FIR) nonlinear systems based on binary-value observation systems. We also apply the kernel trick to the recursive projection (RP) algorithm, yielding a novel recursive algorithm based on a positive definite kernel. For purposes, our approach is compared with the recursive projection (RP) algorithm in the process of identifying the parameters of two channels, with the first of them being a frequency-selective fading channel, called a broadband radio access network (BRAN B) channel, and the other being a a theoretical frequency-selective channel, known as the Macchi channel. Monte Carlo simulation results are presented to show the performance of the proposed algorithm.

Opis:
The satellite-based Automatic Identification System (AIS) system has continuously been developed by the shipping industry in recent years. This paper introduces the satellite-based AIS including the concept, the system structure, the development and its new applications. The Long Range Identification and Tracking (LRIT) system, which is mandatory to be required on certain classes of ships engaged on international voyages to report their position at least every six hours using onboard communication means however, has similar kind of function of ship monitoring with the satellite-based AIS system. Based on the basic introduction of the LRIT system, this paper presents the comprehensive comparison between satellite-based AIS and LRIT in terms of the ship’s cost, the communication scheme, the monitoring coverage, the information details and the information creditability. The conclusion that the satellite-based AIS should be encouraged to effectively play a complement role to the LRIT system is advanced in the paper.

Transformation of simple language blocks into complex syntactical structures are not of a mechanical nature. Since the nature of this process is psychological therefore it is also unique. With the widespread use of printers the role of language traces is rising as a tool for both particular and group forensic identification. The article will discern ways of language trace application in the research of handwriting studies.

The electromechanical actuator (EMA) model is presented with the methods for identifying its design parameters. The actuator is a part of the system for flap deployment on the commercial transport airplane. The differential equations with the feedback control describe behaviour of the actuator deflection. There are two concepts of drive system simultaneously considered: a high torque/low speed (HT/LS) and a geared low torque/high speed (LT/HS). For parameter identification in both cases the Maximum Likelihood (ML) method with two minimisation algorithms: linearized Gauss-Newton and Levenberg-Marquardt is applied. Both approaches for each of two design solutions were effective, while tested on hypothetical data.

Opis:
The current identification algorithm using sonar signal parameters of bandwidth, frequency, duration and pulse waveform which are easy to detect and imitation, to identify the identity of sonar signal, resulting in part of the sonar signal identity is not easy to distinguish. Therefore, an algorithm based on signal feature extraction and digital watermarking is proposed to recognize the uncertain sonar signals. The algorithm embeds the digital watermark into the detection signal from the uncertain sonar. The identity of the signal is recognized by detecting whether the received signal contains watermarks. Experimental results showed that the proposed algorithm can effectively improve the recognition performance of sonar signal source.

The work is devoted to the identification of microstructure parameters of a porous body under thermal and mechanical loads. The goal of the identification is to determine the parameters of the microstructure on the basis of measurements of displacements and temperatures at the macro level. A two-scale 3D coupled thermomechanical model of porous aluminum is considered. The representative volume element (RVE) concept modeled with periodical boundary conditions is assumed. Boundary-value problems for RVEs (micro-scale) are solved by means of the finite element method (FEM). An evolutionary algorithm (EA) is used for the identification as the optimization technique.

Opis:
This article presents Fast-decision Identification Algorithm (FdIA) of Source Emission (SE) in DataBase (DB). The aim of this identification process is to define signal vector (V) in the form of distinctive features of this signal which is received in the process of its measurement. Superheterodyne ELectronic INTelligence (ELINT) receiver in the measure procedure was used. The next step in identification process is comparison vector with pattern in DB and calculation of decision function. The aim of decision function is to evaluate similarity degree between vector and pattern. Identification process mentioned above differentiates copies of radar of the same type which is a special test challenge defined as Specific Emitter Identification (SEI). The authors of this method drew up FdIA and three-stage parameterization by the implementation of three different ways of defining the degree of similarity between vector and pattern (called ’Compare procedure’). The algorithm was tested on hundreds of signal vectors coming from over a dozen copies of radars of the same type. Fast-decision Identification Algorithm which was drawn up and implemented makes it possible to create Knowledge Base which is an integral part of Expert DataBase. As a result, the amount of the ambiguity of decisions in the process of Source Emission Identification is minimized.

Opis:
In the first place, the main identifications of residents of Austrian Galicia in the period between 1772 and 1918 are discussed; emphasised is the fact that diverse individual hierarchies of identification could be formed. Then, it is shown in what ways these identification directions surfaced in the specified local dimension – namely, in the town of Drohobycz (today Ukrainian Drohobych), in the specific historical moment – that is, during the 1911 election for the Vienna Parliament. On this occasion, the local elite carried out the election of their own candidate, contrary to what the majority of local dwellers demanded – which resulted in protest actions and unusual alliances between the locals. Given the exemplary occurrence with its limited place and time framework, the article seeks to analyse the sympathies and antipathies among the Galicians, which tended at times to be astonishing and not necessarily followed the lines of ethnic/national and political divisions. The argument has it that what was happening tended to be contrary to the image of the conflict that split the province’s three main ethnic groups, on the one hand, and the vision of a concordant coexistence between Poles, Ukrainians, and Jews, on the other.

Opis:
The wavelet transform is one of the most effective tools for many tasks concerning signal and image processing, however it is difficult to obtain all of the necessary properties in one scalar wavelet. This leads to the development of new types of transforms such as a multiwavelet transform, which possesses more than one scaling and wavelet function and makes a possibility to combine these functions in order to obtain necessary properties. In the present study the CL2, LV and DGHM multiwavelets were used for an identification of spatial damage in a composite plate based on the analysis of its modal shapes. The obtained results show that some properties of the multiwavelet transform may improve the damage identification algorithm and replace the classical wavelet-based methods

The paper concerns the possibility of application of magnetometry for object identification. One of the basic conditions for successful use of magnetometric methods is the magnetic contrast t of solids towards surroundings. Another possible use e of magnetometry is for local identification of solids in selected areas, which are situated in the local magnetic field. The magnetometer, which enables to measure up to three vector components of magnetic induction and specialized software were used in order to perform the research. Two experiments were carried out within the research.
W pracy zaprezentowano analizy dotyczące możliwości zastosowania magnetometrii do identyfikacji obiektów. Jednym z podstawowych warunków efektywnego wykorzystania metod magnetometrycznych jest pomiar tła magnetycznego obiektów w odniesieniu do otoczenia. Kolejnym możliwym zastosowaniem magnetometrii jest identyfikacja obiektów w lokalnym polu magnetycznym w wybranym obszarze. W przeprowadzonych badaniach wykorzystano magnetometr umożliwiający pomiar trzech składowych wektora indukcji magnetycznej oraz wyspecjalizowane o oprogramowanie. W ramach pracy zrealizowano dwa eksperymenty naukowe.

In this paper the identification problem is considered for initial conditions in a non-minimal state-space model that includes interpretable state variables generated by non-stationary stochastic processes. In order to solve the identification problem, structural restrictions are imposed on initial conditions in a state-space model with redundant state variables. The corresponding restricted maximum likelihood estimator of initial conditions is derived. The restricted estimator of initial conditions can be used in order to compute uniquely identified realizations of interpretable latent variables. The identification problem is illustrated analytically using a simple structural economic model

Opis:
The aerodynamic model of an aircraft can be considered as a mathematical representation of the forces and moments acting on the aircraft. These forces and moments are usually approximated by polynomials as function of aircraft’s state variables. The coefficients in the polynomials are known as the aerodynamic parameters. These aerodynamic parameters are of importance in the evaluation of aircraft performance and stability-control characteristics of an aircraft. These parameters also can be used in the design of, for example, automatic flight control systems and mathematical model of flight simulator. This paper will discuss the principles of the aerodynamic model identification of the aircraft based on flight test data using parameter identification techniques. The paper starts with discussion of a mathematical model of an aircraft. Next, parameter identification techniques will be described. Two techniques often used for estimation of the aerodynamic parameters will be discussed. Results of the modelling and estimation of the aerodynamic parameters, state trajectory of the aircraft, bias errors in the instrumentation system, and calibration factors of the vane-angle of attack from flight test data of the N-250 turboprop aircraft will be presented in this paper. Original achievement of that paper is the mathematical model of a turboprop aircraft.

Opis:
Elastomer materials are commonly used in manufacture of parts of machines and vehicles. A numerical analysis of these elements is possible with many calculation methods, however, due to such properties as incompressibility, very often large deformations, non-linear constitutive compounds, friction and contact phenomena, an analysis by the fmite element method turns out to be a very complicated task. The purpose of experimental studies which were carried out was to determine parameters of hyperelastic materials used for production of elastomer tracks for industrial vehicles. Experiments were carried out with rubber test samples of the hardness close to the hardness of materials used for manufacture of rubber tracks, lining of the driving wheels and track rollers. These parameters were determined for models of hyperelastic materials (Mooney-Rivlin) used for calculations. The obtained results were comparedby numer ical calculations with the help of the finite element method with a model sample at identical load conditions for various models of a material including a material of linear properties (of the constant Young's modulus). Obtained results of studies and numerical analyses demonstrate only a limited potential of the use of linear models for hyperelastic materials - this use is possible only at small deformations. Obtained results of measurements and analyses can be used for proper modelling of parts made of elastomer materials.

Systemy monitoringu wideo od szeregu lat wykorzystywane są w celu zwiększenia poziomu bezpieczeństwa nadzorowanych obiektów i dóbr materialnych. W każdym z wymienionych zastosowań niezwykle istotnym zagadnieniem jest niezawodność procesów nadzoru i monitorowania. W artykule przedstawiono analizę wpływu oświetlenia, odległości obiektu od sensora czy rozdzielczości sensora na poprawną identyfikację. Przeprowadzone badania umożliwiają określenie przydatności systemu monitoringu w określonych warunkach środowiskowych i technicznych.
Nowadays, many areas have to be protected. Monitoring systems (MS) effectively support this kind of processes. A monitoring system provides an image of the area containing the monitored objects. These systems are also used to increase the safety of people. That is why the efficiency is important in the reliable monitoring system (RMS). These issues are interpreted as the possibility of correct identification of the collected data. The reliability of elements, the environmental exposure as well as the process of object detection and face identification analysis have important impact on the MS. Therefore, the main problem of the research is to answer the question: what is the reliability of the identification data (i.e. people) in the real-time monitoring system? The paper presents the main results of the study. The study was conducted in the MS demonstrator consisting of a telecommunication network with implemented video monitoring sensors. Various experiments were performed to adjust the lighting, the distance from the camera and the number of face images in the database. The developed method has to determine the reliability of the identification data. It takes into account the influence of degrading factors which are present in the monitoring system environment. On the basis of the obtained results we specify a set of recommendations for the reference MS.

Opis:
The evolution and functions of the idea of the nation in Serbia from the twilight of eighteenth centuryThis article represents an attempt to describe the functionalisation of the notion of the nation – as an ideological category and theoretical factor which justifies the integrative mechanics in Serbian sociocultural life. It constitutes an elementary point of reference for the historical, philosophical, theological and cultural considerations from the end of eighteenth century. Its understanding, depending on circumstances, can deal with ethnic identity (linguistic-territorial and religious), or have a mystical-nationalistic or socioeconomic dimension. The examples presented herein, taken from the texts of the Serbian thinkers of these various orientations demonstrate that emphasising the biological, ideological or spatial‑linguistic components often results in their inaccurate application and ideologisation. Among the manifestations of national auto-identification presented as characteristically Serbian are the confessional (with an Orthodox distinguishing feature), Slavonic-romantic, folkloristic‑ethnographic, naturalistic-ethical, organic‑organicistic, as well as messianic‑missionist conceptions. Many of them have an eclectic nature and are marked with historical mythology (also nationalistic ethnopsychology), therefore only some are socioculturally objective. Ewolucja i funkcje idei narodu w Serbii od schyłku XVIII wieku W artykule rozpatrywana jest problematyka funkcjonalizacji pojęcia narodu jako kategorii ideowej oraz czynnika teoretycznego uzasadniającego mechanizmy integracyjne w serbskim życiu społeczno-kulturalnym. Stanowi ono elementarny semantyczny punkt odniesienia dla refleksji historycznej, filozoficznej, teologicznej i kulturowej od końca XVIII wieku. Jego rozumienie w zależności od okoliczności może mieć wymiar tożsamości etnicznej (językowo-terytorialnej i religijnej), mistyczno-nacjonalistyczny lub socjoekonomiczny. Analizowane przykłady pochodzą z tekstów serbskich myślicieli tych rozmaitych orientacji (aż do współczesności) i pokazują, że akcent stawiany na składniki biologiczne, ideologiczne lub lingwistyczno-przestrzenne często wiąże się z niedokładnym ich zastosowaniem i ideologizacją. Jako charakterystyczne dla Serbii manifestacje autoidentyfikacji narodowej przedstawia się między innymi takie koncepcje, jak: wyznaniowa z wyróżnikiem prawosławia oraz romantyczno-słowiańska, folklorystyczno‑etnograficzna, naturalistyczno-etyczna, organiczno-organicystyczna, mesjanistyczno-misjonistyczna. Wiele z nich ma naturę eklektyczną i zabarwioną mitologią historyczną (także nacjonalistyczną etnopsychologią) i tylko niektóre cechuje socjokulturowy obiektywizm.

Opis:
The objective of the study was to demonstrate how mitochondrial DNA (mtDNA) can be used to determine the species origin of animal microtraces. The study included pieces of cat and dog hair without the root, a fragment of cooked chicken bone (0.1g), three goose down samples (0.028 g), a pork swab, a pork scratching (5×5×5 mm), and pork lard (0.22 g). DNA was isolated from all of these samples using the method appropriate for the particular source material. The extracts had DNA concentration exceeding 5.4 ng/µl with A260/280 purity range of 1.14-1.88. Next, the samples were subjected to PCR and real-time PCR with species-specific primers and primers complementary to mitochondrial DNA (mtDNA). Control reactions based on the amplification of eukaryotic-specific fragment (18S rRNA) were additionally performed. PCR and real-time PCR products for detection of species-specific mtDNA were obtained for all templates, whereas during the detection of eukaryote DNA no product was obtained for dog and cat hair only. The poor quality of the obtained DNA did not prevent the analysis. The results showed that mitochondrial DNA is suitable for identification of small or highly processed samples, in which genomic DNA often cannot be analyzed.

Opis:
From the surveyed several Brassica oleracea varieties, two viruses have been isolated and identified, namely cauliflower mosaic caulimovirus (CaMV) and tumip mosaic potyvirus (TuMV). Diagnosis was based on the host range, including test plants, on virus properties in sap and in purified virus suspension, on serological tests and on electron microscopic examinations. The third virus, broccoli necrotic yellows cytorhabdo-like virus (BNYV), was detected sporadically, only by electron microscopic observations. It occurred always together with TuMV and/or CaMV. Its isolation was not successful.
Z roślin szeregu odmian botanicznych kapusty warzywnej, wyizolowano i zidentyfikowano 2 wirusy, a mianowicie wirus mozaiki rzepy (TuMV) i wirus mozaiki kalafiora (CaMV). Badania diagnostyczne obejmowały inokulację roślin testowych, określenie właściwości in vitro wirusów, testy serologiczne oraz obserwacje elektrono-mikroskopowe cząstek wirusowych, zarówno w soku jak i w tkankach zainfekowanych roślin. W sporadycznych przypadkach w roślinach porażonych CaMV lub/oraz TuMV, stwierdzano przy pomocy mikroskopu elektronowego, obecność cząstek „baciliform” podobnych do wirusa nekrotycznej żółtaczki brokułów (BNYV). Wirusa tego nie udało się jednak wyizolować i zidentyfikować. Stwierdzono, że wyizolowany CaMV różnił się nieznacznie od opisywanego w literaturze, oryginalnego tzw. „kapuścianego” szczepu B”, natomiast wirus mozaiki rzepy wykazywał typowe cechy szczepu „kapuścianego” TuMV, a pod względem agresywności najbardziej zbliżony był do szczepu niemieckiego.

Opis:
This article studies the relationship between various dimensions of the legitimization of a political system and national identification. The analysis presented here assumes that the emotional attitudes that link people to their place of residence are conditional. The way the state performs its functions should determine how, and to what extent, such attitudes prevail. The hypothesis suggests that a positive evaluation of government policy enhances identification with the state. An empirical study using data from fourteen post-communist countries provides the basis for accepting a considerable part of the hypothesis. People’s evaluation of social policy, of democracy as a system, and their confidence in public institutions, are of central importance for identification. A separate analysis for Poland shows how perceptions of citizens’ equality before the law have a significant impact on national identification.

Opis:
In the paper attention is focused on the necessity to systematize the procedure for determining the shape of transition curves used in vehicular roads and railway routes. There has been presented a universal method of identifying curvature in transition curves by using differential equations. Curvature equations for such known forms of transition curves as clothoid, quartic parabola, the Bloss curve, cosinusoid and sinusoid, have been worked out and by the use these equations it was possible to determine some appropriate Cartesian coordinates. In addition some approximate solutions obtained in consequence of making certain simplifying assumptions orientated mainly towards railway routes, have been provided. Notice has been taken of limitations occurring in the application of smooth transition curves in railway systems, which can be caused by very small values of the horizontal ordinates in the initial region. This problem has provided an inspiration for finding a new family of the so-called parametric transition curves, being more advantageous not only over the clothoid but also over cubic parabola as far as dynamics is concerned.

Opis:
Iterative learning and repetitive control aim to eliminate the effect of unwanted disturbances over repeated trials or cycles. The disturbance-free system model, if known, can be used in a model-based iterative learning or repetitive control system to eliminate the unwanted disturbances. In the case of periodic disturbances, although the unknown disturbance frequencies may be the same from trial to trial, the disturbance amplitudes, phases, and biases do not necessarily repeat. Furthermore, the system may not return to the same initial state at the end of each trial before starting the next trial. In spite of these constraints, this paper shows how to identify the system disturbance-free dynamics from disturbance-corrupted input-output data collected over multiple trials without having to measure the disturbances directly. The system disturbance-free model can then be used to identify the disturbances as well, for use in learning or repetitive control. This paper represents the first extension of the interaction matrix approach to the multiple-trial environment of iterative learning control.

We prove existence of solutions using the concept of H-convergence and employ variational discretization for the discrete approximation of solutions. Using a discrete version of H-convergence we are able to establish the strong convergence of the discrete solutions. Finally we present some numerical results.

Opis:
The paper addresses a two-dimensional boundary identification (reconstruction) problem in steady-state heat conduction. Having found the solution to the Laplace equation by superpositioning T-complete functions, the unknown boundary of a plane region is approximated by polynomials of an increasing degree. The provided examples indicate that sufficient accuracy can be obtained with a use of polynomials of a relatively low degree, which allows avoidance of large systems of nonlinear equations. Numerical simulations for assessing the performance of the proposed algorithm show better than 1% accuracy after a few iterations and very low sensitivity to small data errors.

W pracy przeanalizowano proces zdalnej identyfikacji w tej postaci, w jakiej jest on realizowany obecnie. Na tej podstawie zdiagnozowano najważniejsze słabe strony metod wykorzystywanych w tym procesie. W przypadku metod niebiometrycznych ich główną słabością jest ograniczenie ich stosowania do weryfikacji określonych danych uwierzytelniających posiadanych przez użytkownika (osobę weryfikującą się), a nie do weryfikacji tożsamości per se. Z kolei stosowane współcześnie metody biometryczne są czasochłonne i obarczone subiektywizmem w ocenie zgodności danych biometrycznych ze wzorcem. Alternatywę dla tych metod stanowi zaprezentowany w niniejszym artykule model, który jest oparty na w pełni zautomatyzowanej, zdalnej identyfikacji biometrycznej, wykorzystującej jako wzorzec dane biometryczne zawarte w dokumentach osobistych i paszportach. Model jest wolny od słabości i ograniczeń innych analizowanych biometrycznych i niebiometrycznych metod identyfikacji i charakteryzuje się bardzo niskim poziomem błędu.
The paper presents an analysis of the present-day process of remote identification. On this basis, the most important weaknesses of the methods were diagnosed. With regard to non-biometric methods, the main weakness and limitation is that they only verify Alternatywne narzędzia zdalnej weryfikacji tożsamości | 101 if the user (the person being verified) has appropriate credentials, and they do not verify the identity per se. On the other hand, the currently applied biometric methods are time-consuming and subjective in assessing the compliance of biometric data with the template. An alternative to these methods is a model, presented in this paper, which is based on fully automated, remote biometric identification using biometric data contained in IDs and passports as a template. The model is free from the weaknesses and limitations of other biometric and non-biometric identification methods analysed in this paper and has a very low error rate.

Friction forces present in the PMSM motor exert a very negative influence on its working parameters. Those effects are extremely nonlinear and their consequences have to be acknowledged at designing both the motor’s mechanical construction and its control system. This paper describes a friction coefficients identification method in the PMSM based on the mathematical model. The results of simulation research have been backed up by the real-world object testing. In the first section of this paper a brief summary of the most important aspects of PMSM motors was included while the second one focuses on the theoretical description of friction model that was used during research. Third part of this paper is focused on the detailed description of the PMSM motor model and its simplifying assumptions. The fourth section contains a description and results of concluded research in the Matlab/Simulink environment. Finally, the article concludes with comparison of theoretical results and experimental results obtained from real-world motor.

Acoustic field of vessels is changing along with their speed changing and is associated with acoustic activity of wave sources installed in vessel’s hull (main engines, electric generating sets, reduction gears, pumps, shaft-lines, piping, ventilating ducts etc) as well as hydro-dynamic sources such as screw propellers and water flow around the hull [5, 7]. Vibration energy generated by the onboard devices is transferred through ship structural elements to water where it propagates in the form of hydro-acoustic waves of a wide frequency band.

Opis:
The aim of the statistical analyses carried out was to identify similarities and to point out differences between the various tributaries of the Narew River, to identify the factors and processes responsible for the transformations occurring in the aquatic environment and finally, to identify the main sources of pollution in the river catchment. For the purposes of statistical analysis, the results of studies conducted as part of diagnostic monitoring by the General Inspectorate for Environmental Protection in 2017–2018 were used. The studies included 8 measurement points located directly on the Narew River and 17 points located on its selected left and right tributaries. Analysis of the collected results indicates that the chemical condition of the water in the Narew catchment is assessed as being poor. This observation may be due to the fact that the Narew catchment is mainly used for agricultural purposes and, in addition, there is a relatively large number of potential anthropogenic sources. As part of the analysis, two potential sources of pollution affecting water quality in the Narew catchment were identified, which include surface run-off and treated wastewater inflow.

In studies of movement essential element of the correctness of the obtained results is correct identification of the reference base. One method for such identification, referred to as “all-pairs method”, is to examine the insignificance of the mutual displacement of potential reference points in all combinations of pairs. It is a well known exact method of identification, but its use in practice is limited to the study of vertical displacements. In this work we present the possibility of application of this method in the study of horizontal displacements. Numerical example illustrates the calculation procedure of the proposed method.

Opis:
Wartość dowodowa wyników uzyskanych w trakcie czynności procesowych z udziałem uczestników zdarzenia może być bardzo zróżnicowana. Dotyczy to również okazania osoby, którego wyjątkowa pozycja w procesie karnym wynika z tego, że jednoznaczne rozpoznanie osoby okazywanej przez świadka stanowi dowód bezpośredni o charakterze obciążającym. Problemy związane z weryfikacją wyniku tej czynności, które często występują nie tylko w polskiej praktyce śledczej, zostały zaprezentowane na przykładzie autentycznej sprawy karnej. Podstawowym dowodem oskarżenia było w niej rozpoznanie przez świadka kilku osób podejrzanych o kradzież. Istotne wątpliwości dotyczące ich sprawstwa pojawiły się jednak dopiero po kilku latach od zdarzenia, w trakcie trwania przewodu sądowego. Sąd postanowił wówczas skorzystać z pomocy biegłego z zakresu antropologicznych badań identyfikacyjnych. Wszechstronna analiza zapisu z monitoringu z miejsca zdarzenia wraz z dodatkowymi badaniami dały możliwość obiektywnej oraz dokładnej weryfikacji wyników okazania. Dla oskarżonych opinia z badań antropologicznych stanowiła przede wszystkim dowód odciążający. Ponadto otworzyła ona nowe możliwości w zakresie pozyskiwania informacji, gdy niska jakość obrazów nie pozwala na szczegółową ocenę cech elementów morfologicznych głowy, w tym jej części przedniej, jaką jest twarz.
Probative value of results obtained in the course of legal proceedings with the participants of the criminal act may vary. This also concerns results of identification by an eyewitness. The exceptional role of its result in the criminal trial derives from the fact that categorical identification of a suspect by the witness becomes directly incriminating evidence. Problems connected with verification of identification parade result, which often occur both in Poland and in other countries, have been presented on the basis of a real criminal case. The main evidence submitted by the prosecutor was identification of several people who had been suspected of theft by an eye witness. Some important doubts relating to their guilt, however, arose in the criminal trial in court several years after the crime. The court decided to use the help of an expert in the field of anthropological identification. Comprehensive analysis of the CCTV recordings from the crime scene and additional examinations carried out by an expert made it possible to verify the results of the identification parade objectively and precisely. For the defendants the anthropological opinion was just exculpatory evidence. However, it opened up new possibilities to obtain information, especially when low quality of CCTV recordings does not allow for a detailed analysis of the characteristics of morphological elements of the head including its front part which is the face.

Opis:
For the tuning of servo controllers as well as for monitoring functions, significant parameters of the controlled system are required. In contrast to identification methods with determined input signals, the paper focuses on the problem of identification with regular process movements (non-invasive identification), leading to a lack of power density in some frequency ranges. A nonlinear Least Squares (LS) approach with single mass system and friction characteristic is investigated regarding the accomplishable accuracy and necessary constraints. The proposed method is applicable on industrial motion controllers and has been carried out with a multitude of input sequences. To verify the performance of the approach, achieved experimental results for the model parameters are exposed.

Opis:
Six bacterial strains isolated from the surface water of the southern Baltic Sea were described on the basis of their morphological, physiological and biochemical features, and were classified on the basis of 16S rDNA sequence analysis. Comparative analyses of the 16S rDNA sequences of five of the six bacterial strains examined displayed a ≥98% similarity to the sequences available in the NCBI GenBank. The 16S rDNA sequence of strain 2 shared only a 96% similarity with other published sequences, which suggests that this is a new, hitherto unknown species. The isolated heterotrophic bacteria belong to the families Bacillaceae (strain 1), Flexibacteriaceae (strain 2), Sphingomonadaceae (strains 3, 5), Micrococcaceae (strain 4) and Aurantimonadaceae (strain 6). This is the first study in which the polyphasic approach has been applied to the identification of heterotrophic bacteria from the brackish waters of the Gulf of Gdańsk and Gdańsk Deep.

Opis:
Weryfikacja poprawności podpisów cyfrowych jest obliczeniowo kosztowna. Aby ją zwiększyć, zamiast pojedynczych podpisów weryfikacji poddaje się kolekcje. Jeżeli wszystkie podpisy w kolekcji są poprawne, to cała kolekcja jest akceptowana. Pojawienie się błędnych podpisów w kolekcji powoduje, że weryfikacja jest błędna. Nie można odrzucić całej kolekcji, zachodzi więc konieczność identyfikacji błędnych podpisów w kolekcji. W artykule zdefiniowano metody identyfikacji błędnych podpisów. W szczególności określono weryfikacje typu "dziel i rządź", w których wejściowe kolekcje są dzielone na podkolekcje tak długo, aż końcowe błędne kolekcje zawierają pojedyncze podpisy. Opisano również weryfikator Hamminga identyfikujący jeden błędny podpis w kolekcji oraz uogólniono ten weryfikator do postaci dwupoziomowego weryfikatora, umożliwiającego identyfikacje dwóch błędnych podpisów. Podano też definicję ogólnego weryfikatora zdolnego do identyfikacji dowolnej liczby błędnych podpisów w kolekcjach.
Verification of digital signatures is expensive in terms of computing resources required to perform the task. Batch verification is a technique that uses homomorphic property to increase efficiency. If all signatures are correct in a batch, the whole batch is accepted otherwise bad signature must be identified and rejected. For obvious reasons, rejection of bad batches is not possible as they typically include also valid signatures that must be accepted. In the paper, methods of bad signature identification are defined. In particular, the identification using the "divide and conquer" method is described. In this method the input batch is repeatedly divided into sub-batches until the final sub-batches contain single bad signatures. The Hamming verifier is defined as the one being able to identify a single bad signature. Its generalisation allowing identification of two bad signatures resulting in the so-called two level Hamming verifier, is given. The work concludes with remarks about verifiers that identify arbitrary number of bad signatures.

In engineering the human is considered as one of the system elements. In most studies, his/her model remains unchanged due to the external factors. The present study shows that a relation between the mental stress and human dynamics cannot be neglected. The dynamic characteristics of the operator model change due to external stimuli, i.e., mental stress. The aim of this study was to present identification of a mathematical human model and measurement methodology of the mental stress level. To determine the level of human response to external stimuli, the electrocardiography (ECG) and electromyography (EMG) methods were applied. The results showed difference in model parameters that cannot be neglected during the modeling of the human operator. The present study points to the need of developing simplified human models, taking into account external stimuli that have direct impact on his/her effectiveness. Some interdisplinary investigation provide may benefits combining part of the automation and ergonomics research areas.

Opis:
The Chinese word identification and sentence intelligibility are evaluated by grades 3 and 5 students in the classrooms with different reverberation times (RTs) from three primary school under different signal-to-noise ratios (SNRs). The relationships between subjective word identification and sentence intelligibility scores and speech transmission index (STI) are analyzed. The results show that both Chinese word identification and sentence intelligibility scores for grades 3 and 5 students in the classroom increased with the increase of SNR (and STI), increased with the increase of the age of students, and decreased with the increase of RT. To achieve a 99% sentence intelligibility score, the STIs required for grades 3, grade 5 students, and adults are 0.71, 0.61, and 0.51, respectively. The required objective acoustical index determined by a certain threshold of the word identification test might be underestimated for younger children (grade 3 students) in classroom but overestimated for adults. A method based on the sentence test is more useful for speech intelligibility evaluation in classrooms than that based on the word test for different age groups. Younger children need more favorable classroom acoustical environment with a higher STI than older children and adults to achieve the optimum speech communication in the classroom.

Opis:
The paper presents experimental results on offline signature identification and verification. At the first stage of the presented system, the binary image of the signature undergoes skeletonization process using KMM algorithm to have a thinned, one pixel-wide line, to which a further reduction is applied. For each thinned signature image a fixed number of points comprising the skeleton line are selected. The recognition process is based on comparing the reference signatures with the questioned samples using distance measure computed by means of Shape Context algorithm. The experiments were carried out using a database containing signatures of 20 individuals. For the verification process random forgeries were used to asses the system error. The main advantage of the presented approach lies in utilizing only one reference signature for both identification and verification tasks, whereas the achieved results are comparable with respect to the systems that use several training samples per subject.

Sturgeons (Acipenseridae) are producers of black caviar, which is sold world-wide. Black caviar differs widely in quality, availability, price and taste and for these reasons it is often the subject of commercial fraud. Identification of sturgeon species is frequently based on molecular methods such as analysis of nuclear DNA and mitochondrial DNA. In this study two fragments of microsatellite DNA: Afu-39 and Afu-68 were analyzed. In caviar samples, four alleles were observed in locus Afu-39, and six alleles in locus Afu-68. This paper describes the use of microsatellite DNA markers for species identification of black caviar.

Opis:
The article presents the use of multiple regression method to identify added wave resistance. Added wave resistance was expressed in the form of a four-state nominal function of: “thrust”, “zero”, “minor” and “major” resistance values. Three regression models were developed for this purpose: a regression model with linear variables, nonlinear variables and a large number of nonlinear variables. The nonlinear models were developed using the author's algorithm based on heuristic techniques. The three models were compared with a model based on an artificial neural network. This study shows that non-linear equations developed through a multiple linear regression method using the author’s algorithm are relatively accurate, and in some respects, are more effective than artificial neural networks.

Quick development of computer techniques and increasing computational power allow for building high-fidelity models of various complex objects and processes using historical data. One of the processes of this kind is an air traffic, and there is a growing need for traffic mathematical models as air traffic is increasing and becoming more complex to manage. This study concerned the modelling of a part of the arrival process. The first part of the research was air separation modelling by using continuous probability distributions. Fisher information matrix was used for the best fit selection. The second part of the research consisted of applying regression models that best match the parameters of representative distributions. Over a dozen airports were analyzed in the study and that allowed to build a generalized model for aircraft air separation in function of traffic intensity. Results showed that building a generalized model which comprises traffic from various airports is possible. Moreover, aircraft air separation can be expressed by easy to use mathematical functions. Models of this kind can be used for various applications, e.g.: air separation management between aircraft, airports arrival capacity management, and higher-level air traffic simulation or optimization tasks.

Opis:
Identification plays an important role in relation to control objects and processes as it enables the control system to be properly tuned. The identification methods described in this paper use the Stochastic Gradient Descent algorithms, which have so far been successfully presented in machine learning. The article presents the results of the Adam and AMSGrad algorithms for online estimation of the Dielectric Electroactive Polymer actuator (DEAP) parameters. This work also aims to validate the learning by batch methodology, which allows to obtain faster convergence and more reliable parameter estimation. This approach is innovative in the field of identification of control systems. The researchwas supplemented with the analysis of the variable amplitude of the input signal. The dynamics of the DEAP parameter convergence depending on the normalization process was presented. Our research has shown how to effectively identify parameters with the use of innovative optimization methods. The results presented graphically confirm that this approach can be successfully applied in the field of control systems.

For the considered ferry operating area, there are distinguished four different climate-weather change processes and their states. Further, there are identified the unknown parameters of those processes, i.e. the probabilities of the climate-weather change processes staying at the initial climate-weather states, the probabilities of the climateweather change transitions between the climate-weather states and the mean values of the climate-weather change processes' conditional sojourn times at particular states. Finally, there are predicted the main characteristics of the climate-weather change processes at the distinguished operating area.

Opis:
Micro Coaxial Helicopter with compact size and vertical takeoff ability offers a good Micro Aerial Vehicle (MAV) configuration to handle indoor mission such as search, rescue and surveillance. An autonomous MAV helicopter equipped with micro vision devices could provide more information of the scene, in which the human present is risky. Toward an autonomous flight, mathematical model of the helicopter should be obtained before controller design takes place. This paper will discuss the mathematical modelling, simulation and identification of a micro coaxial helicopter. The mathematical model of the micro coaxial helicopter will be presented, in which total forces and moment are expressed as a Taylor series expansion as function of the state and control variables. The mathematical model will be used to simulate the helicopter responses due to control input. The simulation was used to obtain better understanding of the characteristics of the helicopter before flight test program are performed. Flight test program dedicated to identify the parameter of the micro coaxial helicopter have been carried out. The micro coaxial helicopter was instrumented with sensory system to measure some input and output variables. The use of Kalman filter to estimate the state and total least squares to estimate the aerodynamic parameter of micro coaxial helicopter based on the flight test data will be presented. Some identification results and model validation will be given in this paper.

The paper presents joint operation of AIS-AtoN and radar. There was brought forward a fact of divergence of the information visualized in radar in cases when AIS receivers are produced by different manufacturers. It happens that the AtoN AIS information is not displayed by radar screen. It is also essential that not every ship is provided with AIS equipment; therefore the users cannot always fully take advantage of AtoN AIS in respect of functionality.

The traditional methods of bacterial identification are based on observation of either the morphology of single cells or colony characteristics. However, the adoption of newer and automated methods offers advantage in terms of rapid and reliable identification of bacterial species. The review provides a comprehensive appreciation of new and improved technologies such fatty acid profiling, sequence analysis of the 16S rRNA gene, matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF), metabolic finger profiling using BIOLOG, ribotyping, together with the computational tools employed for querying the databases that are associated with these identification tools and high throughput genomic sequencing in bacterial identification. It is evident that with the increase in the adoption of new technologies, bacterial identification is becoming easier.

Opis:
Aluminium recycling is cost-effective and beneficial for the environment. It is expected that this trend will continue in the future, and even will steadily increase. The consequence of the use of recycled materials is variable and difficult to predict chemical composition. This causes a significant reduction in the production process, since the properties of produced alloy are determined by the inicrostructure and the presence of precipitates of other phases. For this reason, the type and order of formation of precipitates were systematically investigated in recent decades. These studies involved, however, only the main systems (Al-Cu. Al-Mg-Si, Al-Cu-Mg, Al-Mg-Si-Cu), while more complex systems were not analysed. Even trace amounts of additional elements can significantly affect the alloy inicrostructure and composition of precipitates formed. This fact is particularly important in the case of new technologies such as laser surface treatment. As a result of extremely high temperature and temperature changes after the laser remelting large amount of precipitates are observed. Precipitates are nanometric in size and have different morphology and chemical composition. A full understanding of the processes that occur during the laser remelting requires their precise but also time effectively phase identification, which due to the diversity and nanometric size, is a major research challenge. This work presents the methodology of identification of nanometer phase precipitates in the alloy AlSi9Cu, based on the simultaneous TEM imaging and chemical composition analysis using the dispersion spectroscopy using the characteristic X-ray. Verification is performed by comparing the simulation unit cell of the identified phase with the experimental high-resolution image.

Opis:
This article sets out to present the critical role of positioning theory and social identification theory in the discoursal analysis of authorial presence in academic texts by focusing on the dynamic nature of writer identity. Drawing on Harré’s, Fairclough’s and Hall’s work, and my own focus on the relationship between students’ identities and their experience of academic writing, I claim that discoursal identity often establishes itself in relation to difference and that it refers to the various “selves” which writers employ in the act of writing, which locates identity in socio-cultural and institutionally defined subject positions. An empirical case is then presented. It consists of a description of my own semi-ethnographic study1 on the co-construction of authorial identity in student writing in both English and Polish, focusing on the findings of the macro-level analysis of a text corpus. The findings of the study support my other claim that authorial identity is a dynamic concept which cannot be determined entirely by socio-cultural or institutional factors, but is unique for each writer and can be negotiated and changed.

Opis:
This article presents the procedure of identification radar emitter sources with the trace distinctive features of original signal with the use of fractal features. It is a specific kind of identification called Specific Emitter Identification, where as a result of using transformations, which change measure points, a transformation attractor was received. The use of linear regression and the Lagrange polynomial interpolation resulted in the estimation of the measurement function. The method analysing properties of the measurement function which has been suggested by the authors caused the extraction of two additional distinctive features. These features extended the vector of basic radar signals’ parameters. The extended vector of radar signals’ features made it possible to identify the copy of radar emitter source.

Opis:
The paper presents a new, revisited and unified approach to a linear continuous-time dynamic single-input single-output system identification using input and output signal samples acquired with a deterministic constant or random sampling interval. The approach is based on a specially designed identification experiment with excitation of the form of a continuous-time multisine random excitation and digital processing of the corresponding signal samples obtained without analogue antialiasing filtration in the case of disturbances satisfying or not satisfying the Shannon's sampling theorem. Properties of the proposed approach are discussed taking into account nonlinearity of the excitation generation and data acquisition systems with a focus on model identification in the case of input and output signal levels comparable with data acquisition system accuracy. Methods reducing influence of the disturbances (including aliasing) as well as nonlinearities of the excitation generation and data acquisition systems on identification results are proposed, too.

Spośród znanych technik biometrycznych identyfikacji osób zdecydowanie najwyższy poziom wiarygodności uzyskuje się poprzez porównanie profili DNA. W artykule opisano metodykę identyfikacji opartej o profile STR16. Opracowano oryginalne algorytmy identyfikacji osób i oceny pokrewieństwa bazujące na dwóch uniwersalnych wskaźnikach oraz dokonano statystycznej analizy wiarygodności poszczególnych hipotez. Przetwarzanie danych zostało zintegrowane z innymi biometrycznymi technikami identyfikacji.
Amongst the known biometric authentication techniques, the highest rate of credibility is definitely attained by usage of DNA profiling. This paper describes the methodology of identification based on STR profiles. The created algorithms and methods will allow the identification and evaluation of kinship on the basis of two fundamental indicators. It is a different approach from the ones, which are currently being used. However, its credibility has been proven statistically. Data processing has been integrated with other biometric identification techniques.

Tekst został poświęcony badaniom poziomu subtelnego różnicowania wzrokowego oraz określeniu zależności, jaka zachodzi pomiędzy różnicowaniem wzrokowym a identyfikacją liter w izolacji. Badania odnoszą się również do istnienia zależności pomiędzy dokładnością odwzmorowywania figur prostych oraz złożonych i różnie ułożonych w przestrzeni. Oznacza to, że wśród figur składających się na próbę odwzorowywania figur geometrycznych można wyłonić te, które w swojej grupie warunkują dokładność odwzorowywania pozostałych figur. W związku z uzyskanymi wynikami badań, bardzo istotne i uzasadnione staje się podejmowanie działań zmierzających do wykonywania przesiewowych badań diagnostycznych, pozwalających wyłonić uczniów, którzy powinni zostać skierowani na specjalistyczne badania diagnostyczne. Na ich podstawie szkoła będzie mogła podjąć profesjonalne działania pomocowe, mające na celu korygowanie i kompensowanie funkcji, które decydują o przebiegu dalszej edukacji.
The following paper is devoted to research on the subtle visual differentiation and identification of the dependence which exists between the visual differentiation and identification of letters in isolation. The study also refers to the existence of the relationship between the precision of copying simple and complex figures arranged differently in space. This means that, among the figures involved in the attempt to copy geometric shapes, we can distinguish figures which determine the accuracy of copying the remaining figures within the same group. In reference to the obtained test results, it is very important and reasonable to take measures aimed at carrying out screening diagnostic tests that will enable us to distinguish students who should be subject to further specialized diagnostic tests. On their example, the school will be able to introduce professional assistance activities aimed at correcting and compensating functions that determine the course of further education.

This paper examines the factors affecting the performance of VTS operators. A general review of the human factor as a determinant of navigational safety is presented. The elementary nature of the system and its structure are defined, and the ability of a VTS operator to perform planned tasks within a specified timeframe and in a specific manner is analyzed. A reliability assessment scheme is proposed, which is based on the interpretation of factors affecting the VTS operator’s efficiency. The effective performance of VTS operators, along with the specific nature of the maritime environment and reliability of the vessel traffic management support, are key determinants in the process of ensuring the reliability and security of the entire system.
