Modelling of the plasma transport for inherently three-dimensional (3D) problems as in stellarators requires dedicated complex codes. FINDIF is a 3D multifl uid plasma edge transport code that has been previously successfully used for the analysis of energy transport in the TEXTOR-DED tokamak [1], where 3D perturbations led to an ergodic structure of fi eld lines in the plasma edge. The ongoing efforts to apply it meaningfully to Wendelstein 7-X (W7-X) plasma problems resulted in advancements in the main model and accompanying tools for mesh generation and post-processing. In order to verify the applicability of the code and to compare with the reported simulation (EMC3-EIRENE) and experimental (OP1.1) results, a series of simulations for varying plasma density, temperature and anomalous transport coeffi cients as well as for fi xed input power were performed. The connection length pattern of FINDIF traced magnetic fi eld lines on the limiter was reproduced and its impact on heat loads was confi rmed. An increase in the peak heat load on the limiter with a rise in plasma density, temperature and anomalous plasma transport coeffi cients was observed. The decay lengths of density, electron temperature and heat fl ux did not change with density, and were decreasing with temperature and increasing with anomalous plasma transport coeffi cient, which was compared to the simple scrape-off layer (SOL) model.

The article presents the results of an experiment related to wildlife inventory control with the use of data from terrestrial laser scanning. The measurements were performed with the terrestrial laser scanning system – Riegl VZ-400i. The study area was the Obrońców Westerplatte square in Wrocław. The collected measurement data were pre-processed in a commercial – dedicated RiSCAN Pro environment. Operations related to point cloud georeferencing and its filtering were performed. The tree parameters were measured on the basis of a cloud point obtained in field surveys. This operation was performed with the use of the 3D Forest software. The investigations covered the main parameters of the tree (height and diameter) along with additional parameters, such as the distance between two points of the tree located furthest apart, the surface area of the orthogonal projection of the tree on the reference surface (terrain surface) and the height of the tree crown above the terrain surface. As a result of the performed analyses, an inventory of 70 trees was made within the Obrońców Westerplatte square in Wrocław. Part of the experiment was also to prepare a 3D model of a tree by using some available modeling algorithms. This part was performed in Sequoia software - dedicated to such operations. The software offers three modeling algorithms: Zhu/Bridson, metaballs and union of spheres.

Currently, the modelling of historic buildings is most often performed on the basis of data obtained by terrestrial laser scanning. It ensures both the speed of information acquisition and the high accuracy of the final elaboration. However, there are situations in which the terrain layout or the structure of the building limits the possibility of obtaining full information on its shape. In such situations, the solution is to integrate data from various measurement devices. In the case of creating a full 3D model of large buildings, one of the ways to supplement the data, especially the roof of the building, is to use data from airborne laser scanning. The research used the integration of airborne laser scanning data with data recorded with the Leica ScanStation P40 terrestrial laser scanner. Combined point clouds were used for 3D modelling of two different historic buildings in Krakow. Modelling was performed with the Bentley CAD software and in Leica Cyclon 3DR and 3DReshaper. The accuracy of data integration was determined and the advantages and disadvantages of using the above-mentioned software for 3D modelling of architectural objects were shown. The result of the study is a 3D model of St. Florian’s Gate and the Palace of Art in Krakow.

The Potwar sub-basin is an important hydrocarbon producing zone of the Upper Indus basin and has significant oil and gas potential. The Balkassar area is the main oil field of the Potwar sub-basin and oil is mainly produced from Eocene carbonates. The Chorgali Formation is of Eocene age and is the main reservoir rock in this area. Structurally, the Potwar sub-basin is complicated, and surface features often do not reflect subsurface structures. This is due to the presence of detachments at different levels. In such cases, it is necessary to integrate seismic data with geological information for an accurate delineation of subsurface structures. Eleven seismic profiles were interpreted to understand subsurface structural style. To correlate well data with seismic data, a synthetic seismogram has been generated. Time, velocity and depth contour maps have been prepared. A 3D model for the Chorgali Formation has been prepared which confirms that this is a four-way anticlinal structure bounded by faults. It makes this structure more favorable for hydrocarbon accumulation. Moreover, a cross section has been prepared for five wells to show that the Chorgali Formation is spreading. Based on it, to show the relationship between compressional tectonics and basement slope, a 3D structural model has been prepared. In this case study, the Balkassar anticline was interpreted as a four-way closure pop-up structure which provides a structural trap for the accumulation of hydrocarbons. This study will help us understand the accumulation of hydrocarbons in the same type of structural traps in the Potwar sub-basin and in similar kinds of basins. It is also relevant to oil exploration within Pakistan.

Buildings are often complex and hindered by identifying and measuring deformation in both the building itself and its elements. However, we have the assistance of 3D laser scanning technology which allows us to collect geometric data. Scanners are particularly effective for measuring high and hard-to-reach locations. This paper focuses on the measuring and modeling of roof drainage installations, which are usually placed at elevated heights, making it impossible to measure using traditional methods. Rain gutters need constant monitoring in order to fulfill their function and ensure proper drainage of rainwater. Laser scanning produces a point cloud which can be converted in a 3D model using software such as Leica Cyclone, AutoCad and ReCap. This study demonstrates the successful utilization of laser scanning in identifying geometric features and deformations in building installations.

The aim of this research is to evaluate the performance of four UAV image processing software for the automatic estimation of volumes based on estimated volume accuracy, spatial accuracy, and execution time, with and without Ground Control Points (GCPs). A total of 52 images of a building were captured using a DJI Mavic Air UAV at 60m altitude and 80% forward and side overlap. The dataset was processed with and without GCPs using Pix4DMapper, Agisoft Metashape Pro, Reality Capture, and 3DF Zephyr. The UAV-based estimated volume generated from the software was compared with the true volume of the building generated from its as-built 3D building information modeled in Revit 2018 environment. The resulting percentage difference was computed. The average volumes estimated from the four software with the use of GCPs were 4757.448 m3 (3.87%), 4728.1 m3 (2.54%), 4291.561 m3 (11.5%), and 4154.938 m3 (14.35%), respectively. Similarly, when GCPs were not used for the image processing, average volumes of 4631.385 m3 (4.52%), 4773.025 m3 (1.6%), 4617.899 m3 (4.89%), and 4420.403 m3 (8.92%) were obtained in the same order. In addition to the volume estimation analysis, other parameters, including execution time, positional RMSE, and spatial resolution, were evaluated. Based on these parameters, Agisoft Metashape Pro proved to be more accurate, time-efficient, and reliable for volumetric estimations from UAV images compared to the other investigated software. The findings of this study can guide decision-making in selecting the appropriate software for UAV-based volume estimation in different applications.

The sedimentary architecture of the Middle Sanaga deposits in the Central Cameroon Region was studied by combining sedimentological and surface geoelectrical techniques. Lithologic columns from hand augers and pits were correlated to geoelectrical profiles. All of these data were analysed to determine the volumes of lithological units that constitute significant potential geomaterial deposits (gravels, sands, and clays). From surface to depth, geoelectrical results show four main units: conductive GU1 (100 Ωm), semi-resistive GU2 (800 Ωm), resistive UG3 (1000–2000 Ωm), and highly resistive GU4 (over 2000 Ωm). The calibration results identify three lithological units: LU1 composed of poorly sorted pebbles and gravels; LU2 consisting of well-classified medium to coarse sands, asymmetry towards fine to coarse elements; and LU3 consisting of silty clays and clayey sands. Correlation of results assigns UG1 and LU3 to low hydrodynamics, GU2 and LU2 to medium hydrodynamics, and GU3 with LU1 to high hydrodynamics. A 3D filling model has been developed. This model shows that the volume of GU1-LU3 is estimated of 33,549,496 m3 , for GU2-LU2 is estimated of 18,352,728 m3 , and of GU3-LU1 of 7,687,875m3 . This study has important implications for the knowledge and characterization of lithological units, especially geomaterials.

The development of science and technology had a strong impact on all branches of engineering, including geodesy and the possibility of acquiring and processing measurement data. The best example of this is the Terrestrial Laser Scanning, whih can perform measurements in the form of a multi-million-point cloud. The cloud, representing places and objects, becomes a spatial database. The current problem in engineering is no longer data acquisition and processing, but information excess and redundancy. The solution to this problem is optimisation, which is the process of reducing the amount of data. It should implement its assumptions in such a way as to remove or reduce unnecessary information without losing the information presented by an object. This issue is particularly important in the process of using point clouds in 3D modelling at various levels of detail. The appropriate levels of the LOD0–LOD4 model require a different type of data: on the one hand ensuring the obtainment of the appropriate accuracy class in the study, and on the other hand, the data source should not contain too detailed information that is unnecessary for the study, which makes the work harder and slows it down due to the need to operate on a huge amount of redundant information Therefore, the purpose of this paper is to determine the scope of work on the optimisation of the point cloud in order to adjust its number and quality to the needs of individual LODs. The results of the work allowed to determine the scope of data unification for the respective precision groups of 3D models generating.

Rozwój nauki i techniki wpłynął mocno na wszystkie gałęzie inżynierii, w tym również na geodezję oraz możliwości pozyskiwania i przetworzenia danych pomiarowych. Najlepszym tego przykładem jest naziemnym skaning laserowym, który realizuje pomiar w postaci wielomilionowej chmury punktów. Chmura ta, będącą reprezentacją miejsc i obiektów, staje się przestrzenną bazą danych. Aktualnym problem w inżynierii nie jest już pozyskiwanie i przetwarzanie danych, a natomiast nadmiarowością i redundancja informacji. Rozwiązaniem tego problemu jest optymalizacja, czyli proces zmniejszenia ilości danych. Powinien on w taki sposób realizować swoje założenia, aby usunąć bądź zredukować zbędne informacje bez straty informacji prezentowanej przez obiekt. To zagadnienie szczególnie istotne jest w procesie wykorzystania chmur punktów w modelowaniu 3D na różnych poziom szczegółowości. Odpowiednie poziomy modelu LOD0-LOD4 wymagają innego rodzaju danych z jednej strony zapewniających uzyskanie odpowiedniej klasy dokładnościowej opracowaniu, z drugiej źródło danych nie powinno zawierać zbyt szczegółowych informacji, niepotrzebnych dla opracowania, co utrudnia i spowalnia pracę z uwagi na konieczność operowania na ogromnej liczbie nadmiarowych informacji. Dlatego celem niniejszej pracy jest określenie zakresu prowadzonych prac nad optymalizacją chmury punktów, celem dostosowania jej liczby oraz jakości dla potrzeb poszczególnych poziomów szczegółowości LoD. Wyniki prac pozwoliły określić zakres unifikacji danych dla odpowiednich grup dokładnościowych generowania modeli 3D.

Topological properties of objects should be maintained and preserved to concisely represent objects. However, the implementation of 2D topological rules requires the decomposition of 3D objects into lower dimensions to determine topological relationships. This results in 2D topological relationships although the connected objects are in 3D. Hence, accurate representation of 3D connectivity in 3D models is limited. 3D topological rules can be implemented to include topological connectivity in 3D space. This paper implemented an extension of the 27-Intersection Model (27-IM) called the 36-Intersection Model (36-IM) to represent 3D topological adjacencies of two objects in 3D space. This resulted in a 12 × 3 intersection matrix or 36-IM that represented the intersections in terms of dimension and number of separations. Six cases were tested, consisting of “meets”, “disjoint” “intersects at a line”, “intersects at a point”, “contains”, and “overlaps”. The resulting 36-IM matrices provided an accurate representation of how the objects in 3D space were related and their dimension of intersections. The formalisms of the 36-IM matrices were also interoperable which allowed the interpretation of 36-IM using the 9IM and DE-9IM to determine general topological relationships. By examining the intersection of interiors, boundaries and exteriors of 3D objects without object decomposition, 3D topological relationships can be determined as well as the dimension and manner of intersection.

Extremely intensive development of technology has resulted in many innovations. There are new methods of acquiring spatial data, such as laser scanning, unmanned aerial vehicles or digital non-metric cameras, which are the subject of this study. Integration of this data has become a new tool that has expanded existing measurement capabilities, finding applications in 3D modelling, archaeology and monument conservation. Owing to scanning, we can get the coordinates of almost every point of the scanned surface, obtaining full and detailed information about the object dimensions. The level of technical advancement of digital cameras allows them to be successfully used in short-range photogrammetry [27], and recently also in low-altitude aerial photogrammetry (unmanned aerial vehicles). Two different test objects were selected to achieve the intended purpose. The monument located on the 14-meter-high top of the Wanda Mound was adopted as the first object. It consists of a simple rectangular plinth made of brown marble. On its top there is a figure of an eagle with a crown of white marble. On the west wall of the plinth there is an inscription “Wanda” and a drawing showing a sword crossed with a distaff. The following features supported the choice of the monument: interesting shape of the object, which includes both simple geometric forms with large and flat surfaces (plinth), and more detailed surfaces (figure of an eagle); detailed texture of the object (complicated marble veins, wing details). The second object under study was The Helena Modrzejewska National Stary Theatre. The building was rebuilt in the style of Viennese Art Nouveau, so that it fully incorporates into the rest of buildings. Measurements included data obtained from a non-metric camera, Leica ScanStation scanner and DJI S 1000 multi-rotor.

Niezwykle intensywny rozwój technologii od początku obecnego stulecia, zaowocował wieloma innowacjami, również w dziedzinie geodezji i kartografii, a w szczególności w zakresie fotogrametrii i teledetekcji. Oprócz ewolucji znanych już form pomiarów jak przejście ze zobrazowań analogowych na cyfrowe, pojawiły się też nowe metody pozyskiwania danych przestrzennych jak skaning laserowy, bezzałogowe statki powietrzne czy cyfrowe kamery niemetryczne, będące przedmiotem niniejszego opracowania. Integracja tych danych stała się nowym narzędziem, które rozszerzyło dotychczasowe możliwości pomiarowe, jak również znalazło zastosowanie poza branżą geodezyjną, na przykład w modelowaniu 3D, archeologii czy konserwacji zabytków. Dzięki skaningowi otrzymujemy współrzędne niemal każdego punktu skanowanej powierzchni w dowolnym miejscu, nawet już po zakończeniu pomiaru i opuszczeniu obiektu. Otrzymujemy zatem pełną i szczegółową informację o wymiarach obiektu, o znajdującej się wewnątrz infrastrukturze niekiedy trudno dostępnej bądź skomplikowanej. Poziom zaawansowania technicznego aparatów cyfrowych pozwala już od kilkunastu lat na stosowanie ich z powodzeniem w fotogrametrii bliskiego zasięgu [27], a od niedawna także i w fotogrametrii lotniczej niskiego pułapu (bezzałogowe statki powietrzne). Bezzałogowe statki powietrzne okazują się świetnym narzędziem wspomagającym proces zbierania danych o wysokorozdzielczych metrycznych zdjęciach elewacji budynków.

Counteracting the social and educational exclusion of visually impaired people is an important issue in the area of knowledge transfer, also in the area of cultural heritage. Visually impaired people get to know the world in an organoleptic way, where the leading cognitive factor is touch. This type of cognitive method cannot be used in museology and historical architecture. Current attempts to solve this problem lead to the use of additive technology understood as 3D printing. The paper presents a modified procedure for obtaining digital 3D models with the use of Autodesk Inventor version 2021, dedicated to creating scalable replicas of architectural objects using additive technology. The applied procedure uses the decomposition of the object into its components and the acquisition of data from terrestrial 3D laser scanning (FARO Focus 3D scanner, Faro Scene software). Printing in the Fused Filament Fabrication technology of a designed minaret representing the architecture of the Timuridian period (minaret of the Ulugh Beg Madrasa in Samarkand, Uzbekistan), originating from the Silk Road area, was carried out due to the size of the facility, divided into several parts. The obtained replica of the minaret was presented to people with simulated pattern dysfunction and tested in a pilot test. The obtained results confirmed that the decomposition of the object for the purposes of 3D modelling, the diversified scaling of individual elements to make real 3D replicas of the digital model facilitated the kinesthetic recognition of the relevant architectural object for the respondents.

The paper describes an innovative design of a bionic robot for applications in felinotherapy supporting hospital and home psychotherapeutic treatment of bedridden children and adults. The project was engineered by biomimicrating a biological cat, reaching its robotic model. Particular attention in this process was devoted to capturing the essence of feline motorics behavior and the possibility of mapping them in a mechatronic model. The geometry, kinematics and kinetics of this model were analyzed, creating assumptions for its practical implementation in the real mechanism of cat skeleton movement. The used software used the topology of elements in Autodesk Fusion 360 Simulation workspace by performing the critical elements of the mechatronic model in print using SLS technology. The work was also supported by a graphical simulation in the PyBullet environment.

W artykule przedstawiono możliwości wykorzystania sztucznych sieci neuronowych (SSN) do predykcji parametrycznej w profilach otworów wiertniczych, której zastosowanie uzupełniło zestaw informacji we wszystkich otworach wiertniczych zlokalizowanych w obrębie analizowanego obszaru. Zaprezentowana w artykule metodologia może być użyta w przypadku braku możliwości specjalistycznej interpretacji krzywych geofizyki wiertniczej, uzupełniającej brakujące dane. Zestaw wykorzystanych w pracy danych obejmował rozwiązania w profilach 10 otworów wiertniczych, z których cztery otwory charakteryzowały się pełnym zestawem danych analizowanych w ramach niniejszego artykułu, obejmujących prędkość fali podłużnej, porowatość efektywną, nasycenie węglowodorami, moduł Younga i współczynnik Poissona. Wykorzystując technikę działania sztucznych sieci neuronowych, przeprowadzono predykcję brakujących informacji, bazując na relacjach pomiędzy analizowanymi parametrami w otworach, gdzie estymowane dane były dostępne. W ostatnich latach obserwuje się dynamiczny rozwój technologii szeroko pojętego uczenia maszynowego (ang. machine learning) i tak zwanej sztucznej inteligencji. Niewiele pozostaje dziedzin nauki, w których nie miałyby one zastosowania. Tak jest również w branży naftowo-gazowniczej. Parametr nasycenia węglowodorami, pomimo wyzwań, jakie niesie za sobą interpretacja tego parametru, również został poddany próbie estymacji, potwierdzając niskimi wartościami korelacji pomiędzy analizowanymi parametrami, że wymaga zdecydowanie bardziej zaawansowanych prac o indywidualnym charakterze. Wyniki predykcji parametrycznej, poddane wcześniej walidacji poprzez charakterystykę parametrów R (różnica pomiędzy wartością rzeczywistą a estymowaną) i RMSE (pierwiastek błędu średniokwadratowego), zostały w kolejnym kroku zaaplikowane w procesie modelowania przestrzennego wszystkich analizowanych parametrów. Finalnie, w celu wizualizacji różnic pomiędzy wykorzystaniem niepełnego i po części estymowanego zestawu danych w analizie przestrzennej, zaprezentowano mapę średnich wartości wybranego parametru w obrębie analizowanego interwału stratygraficznego. Tak przygotowany zestaw danych pozwolił na bardziej wiarygodne odtworzenie przestrzenne rozkładu parametrów istotnych w kontekście charakterystyki złoża węglowodorów, na podstawie którego w kolejnych etapach możliwa jest wiarygodniejsza ocena potencjału złożowego analizowanego obiektu. Zaprezentowana w artykule metodyka, oparta na rozwiązaniu rzeczywistego problemu badawczego, stanowi alternatywę, dla koszto- i czasochłonnych interpretacji geofizycznych, niekiedy znacznych liczb otworów wiertniczych, szczególnie dla obszarów charakteryzujących się relatywnie niewielką przestrzenną zmiennością i złożonością tektoniczną.

The article presents the possibilities of using artificial neural networks for parametric prediction in borehole profiles, the application of which supplemented the set of information in all boreholes located within the analyzed area. The approach presented in the article will be used when there is no possibility of specialized interpretation of the drilling geophysics curves, supplementing the missing data. The set of data used in the study included solutions in the profiles of 10 boreholes, four of which were characterized by the availability of the full data set analyzed in this article, including compressional wave velocity, effective porosity, hydrocarbon saturation, Young’s modulus and Poisson’s ratio. Using the technique of the operation of artificial neural networks, a prediction of missing information was carried out based on the relationships between the analyzed parameters in the wells, where the estimated data was available. In recent years, there has been a dynamic development of machine learning technology and the so-called artificial intelligence. There are very few fields of science in which they find no application. The hydrocarbon saturation parameter, despite the challenges posed by the interpretation of this parameter, was also subjected to an estimation attempt, confirming the low correlation values between the analyzed parameters and requiring much more advanced work of an individual nature. The results of parametric prediction, previously validated by characterizing the R and RMSE parameters, were applied in the next step in the spatial modeling process of all analyzed parameters. Finally, as part of the visualization of the differences between the use of an incomplete and partially estimated data set in spatial analysis, a map of mean values of the selected parameter within the analyzed interval was presented. The set of data prepared in this way allowed for a more reliable spatial reconstruction of the distribution of parameters important in the context of the characteristics of the hydrocarbon reservoir, on the basis of which, in the subsequent stages, it is possible to more fully assess the deposit potential of the analyzed object. The methodology presented in the article, supported by a real case study, is an alternative to geophysical interpretations that require financial and time resources, sometimes large numbers of boreholes, especially for areas characterized by relatively low spatial variability and tectonic complexity. The condition is the availability of the interpretation in at least several boreholes, constituting a pattern for recreating the variability of the tested parameter / parameters in the remaining profiles of the boreholes.

Numerical 3D parametric models of temperature and thermal gradient distribution within the Polish Carpathians and the Carpathian Foredeep are constructed for the interval between ground level and the 160°C isotherm. The model construction was preceded by detailed analysis of over 500 thermal logs from the area investigated and its closest vicinity. This analysis showed that the vertical changes in temperature and thermal gradient have a non-linear character with no regular pattern in the distribution of the parameters modelled, so a 3D modeling approach was chosen as the most appropriate method for their quantitative description. Furthermore, standardization of the thermal logs was recognized as mandatory so the influence of drilling process would be eliminated. Among a broad array of methods and their preconditions discussed, the Kukkonen-Szewczyk method was selected for the data collected in the study area. Modeling results show a close relationship between thermal gradient, lithology and petrophysical rock properties as well as a correlation between the distribution of positive thermal anomalies and yield of hydrocarbon accumulations within the Carpathian Foredeep. The accuracy of the model has been assessed as ~10%. The model was then used for discussion of hydrocarbon generation and prediction of formation temperature.

The paper presents technical application of TeX high-level, descriptive markup language for processing geological dataset from soil laboratory. Geotechnical measurements included equivalent soil cohesion, absolute and absolute deformation index, soil compressibility coefficient by time of immersion depth, exposure time to compressive strength to samples and physical and mechanical properties (humidity, density). Dataset was received from laboratory based experimental tests of the physical and mechanical properties of soils. Data were converted to csv table and processed by LaTeX. Methodology is based on LaTeX packages: {tikz}, {tikz-3dplot}, {tikzpicture}, {pgfplot}, {filecontetns}, {spy} for 3D plotting showing correlation in variables and descriptive statistical analysis based on the data array processing. Results demonstrated LaTeX scripts and graphics: 2D and 3D scatterplots, ternaries, bar charts, boxplots, zooming techniques detailing fragment of the plot, flowchart. Research novelty consists in technical approach of TeX language application for geo- logical data processing and graphical visualization. Engineering graphics by TeX was demonstrated with screenshots of the codes used for plotting.
