Koncepcja przygotowania do życia, która przez długi czas była głównym celem systemów edukacyjnych na całym świecie, stała się zbędna w otwartej perspektywie przez ogromne transformacje w społeczeństwie spowodowane zmianami w technologii i gospodarce. Pięćdziesiąt lat temu uczenie się przez całe życie mogło być postrzegane jako opcja dla osób dysponujących większą ilością wolnego czasu. Teraz stało się ono koniecznością. Oferty edukacyjne i szkoleniowe są dziś segmentowane i zróżnicowane, zgodnie z wymaganiami konsumentów, którzy płacą za moduły edukacyjne dostosowane do ich własnych potrzeb. Kształcenie na odległość jest tylko jednym z przejawów tej nowej orientacji konsumenckiej instytucji szkoleniowych. Akumulacja punktów i transfer, modularyzacja kursów są częścią tej samej strukturalnej transformacji procesu edukacyjnego.

Opis:
In this study, it is aimed to investigate the effects of particle impingement angle and velocity on the surface roughness, erosion rate, and surface morphology of solid particle eroded Ti6Al4V alloy. Ti6Al4V samples were eroded in erosion test rig under various particle impingement angles (15°, 30°, 45°, 60°, 75° and 90°) and impingement velocities (33 m/s, 50 m/s, and 75 m/s) by using 120 mesh garnet erodent particles. Subsequently, erosion rates and surface roughness values of samples were analyzed and calculated as a function of particle impingement angle and velocity. Moreover, 3D surface morphologies of the eroded samples were prepared by using high definition scanner and image processing programs. Results show that erosion rates, surface roughness values and surface morphologies of Ti6Al4V alloy have been varied significantly depending on the both particle impingement angle and velocity. Erosion rates of Ti6Al4V alloy were decreased with increases in particle impingement angle; on the other hand, the surface roughness values were increased with increases in particle impingement angle. Both erosion rates and surface roughness values were increased with increases in particle impingement velocity. Finally, the surface morphologies of the eroded samples were evaluated deeply. It is concluded that the surface morphology variation of the Ti6Al4V alloy depending on the particle impingement angle and velocity were well correlated with the erosion rates and the surface roughness values.

Opis:
This paper investigates the impact of Digital Terrain Model (DTM) resolution on the calculation of the sediment transport capacity coefficient LS within the Bystra catchment, employing various methods through GIS software. The study focuses on the significant role of GIS in environmental research and process modeling, emphasizing the relevance of LS coefficient analysis in morphometry, hydrology, and geomorphology, particularly in the context of agricultural soil erosion. The study presents results from calculating the sediment transport capacity factor LS using three methods for different resolutions (1, 5, 10, 30, 90 meters). LS coefficient determination relies on the catchment area map and slope map, the latter determined using two methods. The catchment area considered is that of the Bystra River, a right tributary of the Vistula, flowing through Nałęczów, Wąwolnica, Celejów, Bochotnica in the Lublin Province. Upon determining the LS coefficient, variations in results are observed, dependent on the chosen method. The discussion section highlights differences in LS coefficient maps based on resolution and method, with notable distinctions in the north-western part for a 10-meter resolution. Analyzing LS coefficient maps at different resolutions, the study observes variations in results based on the method employed. Higher LS coefficient values are noted in the river channel for a 1-meter resolution, attributed to factors such as river bed structure, building rocks, terrain slope, and climate. The conclusions emphasize the use of specific methods for determining slope rasters and highlight the Desmet and Govers method as yielding smaller variances in LS coefficient determination compared to other methods. The study recommends DTM models with resolutions of 1, 5, and 10 meters for LS modeling, considering their beneficial influence on variance and resolution. In summary, this paper contributes valuable insights into the influence of DTM resolution on LS coefficient calculations, providing a nuanced understanding of the interplay between methods, resolution, and terrain characteristics in the context of sediment transport capacity.

The specially elaborated glasses with high values of refractive indices were investigated in the prepared testing stand. The glasses have possessed the refractive index values n in the range 1.6 ≤ n ≤ 2.2. For the glasses the values of the Verdet constants for two waveguides: $λ_1$ = 635 nm and $λ_2$ = 1550 nm were determined. The obtained results showed that the elaborated on the base of new glasses optical fibres are much more sensitive on the action of magnetic field than the silica fibres.

The paper deals with the optical fibre current sensor based on new optical fibre made of glass with a high value of refractive index. This kind of glass was developed to meet the requirements of these optical fibres. The aim of investigations was to develop a new optical fibre with adequate magneto-optical properties and a relatively weak linear birefringence resulting from the process of its production. These features are of essential importance for optical fibre current sensors. The results of investigations concerning such optical fibres have been presented, displaying satisfactory magneto-optical properties, as well as only low linear birefringence induced by stresses arising in the course of their manufacturing.

Opis:
The authors of the presented paper deal with investigations concerning applications of the optical fiber sensor of the magnetic field in electric DC engines with permanent magnets. The aim of the sensor is to measure the state of magnetization of permanent magnets (basing on the measurements of magnetic field induction). The knowledge of the state of magnetization helps to decide whether permanent magnets need to be additionally magnetized in order to prevent damages of the whole engine. This can be done automatically, even when the engine is running. For the purpose the Faraday magnetooptic effect is used. The presented investigations concern an optical fiber sensor of the magnetic field provided with a glass rod characterized a high value of the Verdet constant as the sensing element. Thanks to the application of optical fibers the connection of the sensor head with the whole measuring system is constructed of insulating material without using of electrical connections.

The present paper deals with investigations concerning optical fibre current sensors. They are mainly applied in measurements of the intensity of the electric current in the power lines as so-called optical transformers of the electrical current. The most important advantages of fibre current sensors are: safety of service, insulating power as well as their insensitiveness to electromagnetic interference. The investigations were concentrated on designing of adequate sensing fibre, and particularly on the choice of an adequate kind of glass, of which this fibre could be made. Besides, also the head of the fibre current sensor was designed, basing on the suggested and produced sensing fibre. The paper presents the results of magneto-optic tests of the glass and the sensing fibre.

Opis:
Optical data storage is a rapidly developing technique, which emerges in many varieties. Magneto-optical recording, in particular, applies amorphous rare earth/transition metal films, where a binary coded information is written thermomagnetically and is read by the magneto-optical Kerr or Faraday effect. To increase the writing speed and the recording density, techniques for direct overwrite and magnetically induced superresolution were proposed, which involve these of exchange coupled double layer systems as a storage media. In this paper, the principles and the properties of exchange coupled double layers are discussed with respect to the direct overwrite and the magnetically induced superresolution processes. A formalism based on a switching field diagram is developed yielding all information necessary to achieve reliable and practical writing procedures. As an example, the direct overwrite capability is demonstrated experimentally in antiparallel coupled layer systems.

Opis:
Squirrel cage induction motors suffer from numerous faults, for example cracks in the rotor bars. This paper aims to present a novel algorithm based on Least Squares Support Vector Machine (LS-SVM) for detection partial rupture rotor bar of the squirrel cage asynchronous machine. The stator current spectral analysis based on FFT method is applied in order to extract the fault frequencies related to rotor bar partial rupture. Afterward the LS-SVM approach is established as monitoring system to detect the degree of rupture rotor bar. The training and testing data sets used are derived from the spectral analysis of one stator phase current, containing information about characteristic harmonics related to the partial rupture rotor bar. Satisfactory and more accurate results are obtained by applying LS-SVM to fault diagnosis of rotor bar.

Opis:
The magnetooptics of an asymmetric layered waveguide structure is discussed to investigate the possibility of creating new devices that combine both nonreciprocity and nonlinearity. After addressing some fundamental magnetooptic properties and the kind of materials needed, a straightforward envelope theory is given that exploits the Voigt effect instead of the more obvious Faraday effect. It is emphasised that this choice leads to desirable design features. It is proposed that the introduction of an applied magnetic field to a waveguide structure can be achieved through the use of thin current-carrying strips. It is emphasised that the strips can be arranged to any degree of complexity and that a high degree of control over spatial soliton dynamics can be achieved. Spatial soliton light beams are selected because they can be generated, within a waveguide, in a stable form. The attractive features of using the type of magnetooptic waveguide investigated here are highlighted with examples and it is concluded that the formats proposed can be used for the fully integrated isolator capacity that modern laser systems demand.

The magnetization processes can be effectively studied using magnetization-induced second-harmonic generation effect (MSHG). The aim of the current work is the investigation of inhomogeneous magnetization distributions induced in the surface area of the garnet film by ion implantation. The studies were performed on magnetic garnet film of (111) symmetry, implanted with H⁺₂ ions of 1.5 × 10¹⁶ cm¯² dose and 60 keV energy. The measurements of MSHG effect were performed as a function of the sample rotation angle and the amplitude of external magnetic field. The observed MSHG intensity hystereses were subjected to a decomposition procedure into contributions having different magnetic field dependences. The contributions originating from the implanted and unimplanted parts of the film volume of different magnetic ordering were analyzed and discussed.

Opis:
The paper deals with frequency estimation methods of sine-wave signals for a few signal cycles and consists of two parts. The first part contains a short overview where analytical error formulae for a signal distorted by noise and harmonics are presented. These formulae are compared with other accurate equations presented previously by the authors which are even more accurate below one cycle in the measurement window. The second part contains a comparison of eight estimation methods (ESPRIT, TLS, Prony LS, a newly developed IpDFT method and four other 3-point IpDFT methods) in respect of calculation time and accuracy for an ideal sine-wave signal, signal distorted by AWGN noise and a signal distorted by harmonics. The number of signal cycles is limited from 0.1 to 3 or 5. The results enable to select the most accurate/fastest estimation method in various measurement conditions. Parametric methods are more accurate but also much slower than IpDFT methods (up to 3000 times for the number of samples equal to 5000). The presented method is more accurate than other IpDFT methods and much faster than parametric methods, which makes it possible to use it as an alternative, especially in real-time applications.

Opis:
The paper presents problems related to road safety in terms of the development of the concrete barriers system, dispersing energy of car collision on the roads with high traffic and high accident risk. Particular attention was paid to barriers' basic parameters - weight and length of the segment. The main objective of the numeric researches was to assess the qualitative and quantitative effects of the car collision with a concrete road barrier in accordance with the standard EN 1317. To the model tests a 900 kg passenger car has been used which allowed to perform TB11 test according to EN 1317-2 standard (initial velocity - 100 km/h). Numerical studies were carried out for concrete segments lengths: 2, 4, 6, 8 m for two selected impact points. Detailed comparisons of simulation test results obtained for individual variants were made on the basis of the acceleration courses of selected car bodywork points, calculated indicators, the trajectory of vehicle movement after collision as well as on the basis of the behaviour of the concrete barriers.
Niniejsza praca stanowi rozwinięcie problematyki bezpieczeństwo ruchu drogowego w aspekcie opracowania systemu betonowych barier ochronnych, rozpraszających energią zderzenia samochodu na drogach o dużym natężeniu ruchu i wysokim zagrożeniu wypadkowym, ze szczególnym uwzględnieniem jej podstawowych parametrów konstrukcyjnych (masy i długości segmentu). Głównym celem przeprowadzonych badań numerycznych było dokonanie oceny jakościowej i ilościowej skutków zderzenia samochodu z betonową barierą drogową zgodnie z obowiązującą normą EN 1317. Obliczenia przeprowa-dzono w systemie LS - DYNA wykorzystującego metodę elementów skończonych. Pojazd badany o masie 900 kg poruszał się z prędkością początkową 100 km/h, a następnie uderzał w system barier. Badania numeryczne zrealizowano dla segmentów betonowych o długościach: 2, 4, 6, 8 m, dla dwóch wybranych punktów zderzenia. Szczegółowych porównań wyników badań symulacyjnych, otrzymanych dla poszczególnych wariantów obliczeniowych, dokonano na podstawie przebiegów czasowych przyspieszeń wybranych punktów nadwozia samochodu, obliczonych na ich podstawie wskaźników, trajektorii ruchu pojazdu po zderzeniu, a także na podstawie zachowania się betonowej bariery ochronnej.
