Opis:
Objectives During computed tomography (CT), a large amount of ionizing radiation is emitted to ensure high quality of the obtained radiological image. This study measured the dose distribution around the CT scanner and the exposure of people staying near the CT scanner during the examination. Material and Methods The measurements used an anthropomorphic phantom to assess human exposure to ionizing radiation. The probability of inducing leukemia and other cancers as a result of absorbing doses recorded around the CT device was also calculated. Results The highest exposure to scattered radiation in the proximity of the CT scanner is recorded at the gantry of the tomograph, i.e., 55.7 μGy, and the lowest, below lower detection limit of 6 μGy at the end of the diagnostic table. The whole-body detector placed on the anthropomorphic phantom located at the diagnostic table right next to the CT gantry recorded 59.5 μSv and at the end of the table 1.5 μSv. The average doses to the lenses in these locations were: 32.1 μSv and 2.9 μSv, respectively. Conclusions The probability of induction of leukemia or other types of cancer is low, but the need for people to stay in the examination room during a CT examination should be limited to the necessary minimum.

Opis:
The dynamic development of microelectronics and wireless communication at the turn of the 20th and 21st centuries contributed to the increase in the availability and popularity of all kinds of unmanned platforms, air, land, surface, and underwater. In the case of unmanned aerial vehicles (UAVs), also popularly known as drones, the significant (crucial) advantages are high freedom of motion (i.e., the ability to move in three planes) and the possibility of using it practically anywhere (as opposed to water platforms). These factors influenced the dynamic development of this market sector and the high availability of various models and equipment. UAVs are being used in many sectors and services, both for civil and military purposes. Widespread availability, low cost, and ease of use also favor the possibility of using civilian UAVs for criminal, smuggling, terrorist, or military purposes. Recent armed conflicts, e.g., in Nagorno-Karabakh or Ukraine, and the situation on the eastern Polish-Belarusian border clearly show this. All countries recognize the potential and threat posed by the development of unmanned platforms. Therefore, for several years, special attention has been paid to analyses and research in sensors, effectors, and anti-drone systems. It is worth emphasizing that some effectors (e.g., jammers or spoofers) may significantly affect the navigation process of neighboring objects that use global navigation satellite systems (GNSSs). On the other hand, the use of anti-drone systems is important, especially in the context of protecting institutions and facilities of companies, state administration (i.a., embassies, consulates), army, strategic importance objects (e.g., related to energy, chemical industry), or protection of mass events. In this paper, we present an overview of solutions available on the market and development directions in the field of anti-drone technology.

Selected geometric properties of cauliflower heads cv. Gohan F1 were analyzed by building numerical models with the use of a 3D scanner. Geometric models of cauliflower heads were developed in ScanStudio HD PRO, FreeCAD, and MeshLab programs. Five geometric models describing the shape of cauliflower heads were generated with the use basic geometric figures and drawing tools in FreeCAD. The geometry of numerical models and geometric models was compared in GOM Inspect. The surface area, volume, and detailed geometric dimensions of the developed models were determined. The deviations in cauliflower dimensions calculated by geometric models were mapped. The surface area, volume, and geometric dimensions of cauliflower heads were most accurately represented by the model generated with the Quadric Edge Collapse Decimation (QECD) function. In this model, the relative error of surface area measurements did not exceed 5%, and the relative error of volume measurements did not exceed 4%. This model was also characterized by the smallest average maximum deviation (+) and the smallest average minimum deviation (-) which was estimated at 8%. The proposed geometric model can be used for research and design purposes.

Opis:
Numerical models approximating a kernel shape in wheat cv. Eta were developed with the use of a 3D scanner and applied to analyze selected geometric properties of wheat kernels. Geometric models were built in ScanStudio HD PRO, FreeCAD, and MeshLab programs. Ten geometric models describing the shape of wheat kernels were generated with the use of basic geometric figures and drawing tools in FreeCAD. The geometry of numerical models and geometric models was compared in GOM Inspect. The surface area, volume, and accurate geometric dimensions of the developed models were determined. Deviations in the dimensions of geometric models were mapped. The relative error of surface area measurements was the lowest in solid of revolution obtained by rotating a polygonal chain around an axis at 0.36%. The relative error of measurement reached 4.44% in sphere and around 5% in solid of revolution obtained by rotating two curves around an axis and solid of revolution obtained by rotating three curves around an axis. The relative error of volume measurements was the lowest in rotational ellipsoid (spheroid) and ellipsoid at 3.58% and 4.48%, respectively. The developed geometric models can be used in research and design.

Za pomocą podstawowych brył geometrycznych oraz dostępnych funkcji rysunkowych w programie FreeCAD zbudowano dziesięć modeli geometrycznych o kształcie zbliżonym do ziarna pszenicy. Porównanie geometrii modeli numerycznych i modeli geometrycznych wykonano programem GOM Inspect. Określano pole powierzchni, objętość oraz dokładne wymiary geometryczne modeli. Wykonano mapy odchyłek wymiarów dla badanych modeli geometrycznych. Błąd względny pomiaru pola powierzchni dla modelu geometrycznego zbudowanego jako bryła obrotowa na podstawie obrysu wykonanego za pomocą łamanej był najmniejszy i wynosił 0,36%. Błąd względny dla kuli wynosił 4,44%. Błąd względny dla modelu geometrycznego zbudowanego jako bryła obrotowa z wykorzystaniem obrysu wykonanego za pomocą dwóch łuków oraz modelu geometrycznego zbudowanego jako bryła obrotowa z wykorzystaniem obrysu wykonanego za pomocą trzech łuków wynosił około 5%. Błąd metody pomiaru objętości jest najmniejszy dla elipsoidy obrotowej oraz elipsoidy i wynosił odpowiednio 3,58% i 4,48%. Zaproponowane modele geometryczne można wykorzystać w pracach badawczych i projektowych.

Opis:
A wide variety of retailers (supermarkets, home electronics, Internet shops, etc.) provide scanner data containing information at the level of the barcode, e.g. the Global Trade Item Number (GTIN). As scanner data provide complete transaction information, we may use the expenditure shares of items as weightsfor calculating price indices at the lowest (elementary) level of data aggregation. The challenge here is the choice of the index formula which should be able to reduce chain drift bias and substitution bias. Multilateral index methods seem to be the best choice due to the dynamic character of scanner data. These indices work on a wholetime window and are transitive, which is key to the elimination of the chain drift effect. Following what is called an identity test, however, it may be expected that even when only prices return to their original values, the index becomes one. Unfortunately, the commonly used multilateral indices (GEKS, CCDI, GK, TPD, TDH) do not meet the identity test. The paper discusses the proposal of two multilateral indices and their weighted versions. On the one hand, the design of the proposed indices is based on the idea of the GEKS index. On the other hand, similarly to the Geary-Khamis method, it requires quality adjusting. It is shown that the proposed indices meet the identity test and most other tests. In an empirical and simulation study, these indices are compared with the SPQ index, which is relatively new and also meets the identity test. The analytical considerations as well as empirical studies confirm the high usefulness of the proposed indices.

Opis:
Scanner data are electronic transaction data most often from retail chains and obtained from electronic retail terminals. The identification of products takes place after scanning their characteristic barcode (e.g. EAN or GTIN), thus in the case of scanner data, we have full product information (price, sales volume, weight, description, etc.) at the most disaggregated level. In the cases of many countries, as well as Poland, this type of data is a valuable alternative source of information when estimating inflation. This paper discusses the main advantages but also the challenges of using scanner data in the CPI measurement. The main purpose of the paper, however, is to discuss the problem of selecting an optimal price index formula that would be appropriate for the highly dynamic (in terms of product rotation) scanner data. The considerations, supported by examples of empirical studies, will be demonstrated using the PriceIndices package in the R environment.

Opis:
Although laser scanning ideas and hardware solutions are well-known to experts in the field, there is still a large area for optimization. Especially, if long-range and high-resolution scanning is considered, the smallest defects in optical quality should be perfected. On the other hand, the simplicity, reliability, and finally the cost of the solution plays an important role, too. In this paper, a very simple but efficient method of optical correction is presented. It is dedicated to laser scanners operating from inside cylindrical glass domes. Such covers normally introduce aberrations into both the laser beam and receiving optics. If these effects are uncorrected, the laser scanner performance is degraded both in terms of angular resolution and maximum range of operation. It may not be critical for short-range scanning applications; however, if more challenging concepts are considered, this issue becomes crucial. The proposed method does not require sophisticated optical solutions based on aspheric or freeform components, which are frequently used for similar purposes in imaging-through-dome correction but is based on a simple cylindrical refractive correction plate.

Opis:
One of the greatest challenges facing official statistics in the 21st century is the use of alternative sources of data about prices (scanned and scraped data) in the analysis of price dynamics, which also involves selecting the appropriate formula of the price index at the elementary group (5-digit) level. When consumer price indices of goods and services are constructed, a number of subjective decisions are made at different stages, e.g. regarding the choice of data sources and types of indices used for the purpose of estimation. All of these decisions can affect the bias of consumer price indices, i.e. the extent to which they contribute to the overall uncertainty about the resulting index values. By measuring how robust consumer price indices are, one can assess the impact that the decisions made at the different stages of index construction have on the index values. This assessment involves analysing uncertainty and sensitivity. The purpose of the study described in the article was to determine how much and in which direction the consumer price index changes when including scanner and scraped data in the analysis, in addition to the data on prices collected by enumerators. The impact of these new data sources was assessed by analysing uncertainty and sensitivity under the deterministic approach. To the best of the authors' knowledge, it is a novel application of robustness analysis to measure inflation using new data sources. The empirical study was based on data for February and March 2021, while scanner and scraped data about selected categories of food products were obtained from one retail chain operating hundreds of points of sale in Poland and selling products online. It was found that the choice of a data source has the most significant impact on the final value of the index at the elementary group level, while the choice of the aggregation formula used to consolidate different data sources is of secondary importance.

Opis:
In dentistry, 3D intraoral scanners (IOSs) are gaining increasing popularity in the production of dental prostheses. However, the quality of an IOS in terms of resolution remains the determining factor of choice for the practitioner; a high resolution is a quality parameter that can reduce error in the production chain. To the best of our knowledge, the evaluation of IOS resolution is not clearly established in the literature. This study provides a simple assessment of resolution of an IOS by measuring a reference sample and highlights various factors that may influence the resolution. A ceramic tip was prepared to create a very thin object with an edge smaller than the current resolution stated by the company. The sample was scanned with microCT (micro-computed tomography) and an IOS. The resulting meshes were compared. In the mesh obtained with the IOS, the distance between two planes on the edge was approximately 100 micrometers, and that obtained with microtomography was 25 micrometers. The curvature values were 27.46 (standard deviation - SD) 14.71) μm-1 and 5.18 (SD 1.16) μm-1 for microCT and IOS, respectively. These results show a clear loss of information for objects that are smaller than 100 μm. As there is no normalized procedure to evaluate resolution of IOSs, the method that we have developed can provide a positive parameter for control of IOSs performance by practitioners.

Opis:
Projektowanie nahełmowego systemu wyznaczania celów opiera się na następujących założeniach. Głowica wskaźnika nahełmowego zawiera dwa skanery oparte na wielopłaszczyznowych pryzmatach zwierciadlanych, tworzących wachlarzowate pola widzenia. Trzy diody LED na hełmie lotnika tworzą płaszczyznę, której normalna jest równoległa do linii widzenia wskaźnika nahełmowego. Kąty namiaru diod LED są mierzone metodą triangulacji i obliczane jest położenie kątowe linii widzenia. Dwie opcje organizacji procesu skanowania są analizowane. W pierwszej wersji jeden z pryzmatów obraca się zgodnie z ruchem wskazówek zegara, a drugi - przeciwnie do ruchu wskazówek zegara. W drugiej wersji oba pryzmaty obracają się w tym samym kierunku, na przykład zgodnie z ruchem wskazówek zegara. Wykazano, że jeśli oba pryzmaty obracają się w tym samym kierunku, to dokładność wyznaczania celu jest większa. Opracowany algorytm dotyczący dokładności wyznaczania celów może być wykorzystany przy doborze prędkości skanowania oraz parametrów geometrycznych systemu nahełmowego wyznaczania celów przy zadanej dokładności.
Following design principles are important for helmet-mounted targeting systems. Two scanners on base of the polygonal reflector-type prisms forming the fanned field of view are fastened to head-up display. Three LEDs installed on pilot helmet form a plane, the normal of which is collinear to helmet indicator viewing line. Angles of LED bearings are measured with triangulation method and angular position of viewing line is calculated. Two options for organization of scanning process are analyzed in the paper. In the first variant, one prism rotates in clockwise and the other in counterclockwise direction. In the second variant both prisms rotate in the same direction, clockwise for example. It is shown that if the prisms rotate in the same direction the targeting accuracy is greater. The algorithm developed for determination of targeting accuracy may be used to matching the rate of scanning and geometric parameters of helmet-mounted targeting system at prescribed accuracy of targeting.

Opis:
The Lower Paleozoic shales of SW Sweden and Eastern Pomerania (Poland) have a common history related to the depositional and tectonic evolution of the Baltic Basin. The major tectonic events are recorded, among others, as joints, which are either exposed in outcrops in SW Sweden or recognised in deep boreholes located in Pomerania. We present a comparison of the regional joint systems recognized by multiple methods in the studied region. In effect of a statistical compilation of measurements, five joint sets (named JS 1 to JS 5) were identified, traceable between Eastern Pomerania and SW Sweden. Our analysis showed a general consistency of joint set orientations, independent of their distance to the Tornquist tectonic zone passing through the study region. Three of the joint sets, JS 1 striking NNE, JS 2 striking WNW, and JS 3 striking NNW, are found to be the most frequent sets, occurring in most sites. Having more constant orientation, the JS 1 and JS 3 served as indicators of possible rotation of the tectonic block or stress field in the region. JS 1 and JS 2 are interpreted as an effect of late Carboniferous stress relaxation after Variscan collision, while JS 3 and the E–W striking JS 4 might be related to the Early Devonian Caledonian compressive stage.

Opis:
3D optical scanning method, is employed to digital shape and geometric dimension analysis of fuel tanks. The following paper presents the application possibilities of the optical 3D measurement method for measuring and archiving dimensions of geometrically complex parts, on the example of a passenger car fuel tank in local company. Based on the conducted measurements, for a specific type and size of the population of fuel tanks, proposed model that classifies the geometric accuracy of the tanks produced in the production line. For the analysis and data processing different informatics techniques have been used. The main objective of theirs was to identify the possibility of implementing the system for automation of the measurement to the production line. The measurements were implementation at local company - a manufacturer of polymer tanks in the automotive industry. For most of the measuring points, the mean value of the measuring deviations ranged from -1 mm to +1 mm. The mean values of the standard deviations are presented for a representative deviation of the X dimension of 0.1; 5; 10; 15 and 20 mm were respectively: 0.014; 0.150; 0.172; 0.289; 0.340 mm. The dimensional shape assessment of the manufactured tanks is extremely important from the point of view of the automation of this task in the production line. The optimization of the measurement of tanks carried out in laboratory conditions was implemented on the production line. The main task of optical scanning for the assessment of dimensional conformity has not been used so far in factory. This is due not only to the cost of such systems, but also to certain limitations that have been resolved thanks to laboratory tests. The obtained results of the metrological inspection make it possible to identify significant dimensional and shape deviations of automatically manufactured tanks. The proposed use of artificial neural networks allows the production with a high quality of tanks accuracy with the minimum the number of scanned tanks in the production line. The paper also presents the possibilities of the computer software to analyze the deviations of geometrically very complex parts.

Opis:
This article analyzes the 1977 science-fiction novel A Scanner Darkly by Philip K. Dick, and focuses on the split personalities of the main character: Bob/Fred/Bruce. The reading is supplemented by the use of the concepts of Line of Flight and Body without Organs introduced by Gilles Deleuze and Félix Guattari in Capitalism and Schizophrenia as well as Catherine Malabou’s concept of brain plasticity. The article argues that the progressing deterioration of the protagonist’s mental state caused by drug abuse and social environment may be seen as a representation of a “botched BwO” – a body that has lost its productive potential and cannot be reintegrated into a stable territory. At the same time, I contend that the final chapter of the novel depicts a reparative transformation in which, thanks to brain plasticity, he is integrated into an autopoietic system of his environment.

Biometrics is one of the basic detection techniques used in law enforcement activities on a daily basis. Like other techniques, it is constantly changing. This article aims to provide an overview of what was in the past, what is now, and what will be in the near future. It presents the selected methods of collecting some of the data, as well as the systems used to process them. In addition, practical guidance is provided on how individual biometric data should be collected and, for specific cases, it explains why the data collection procedure is carried out in one way and not another, and what it means for its subsequent processing. As problems sometimes arise during recovery of the material they have been presented together with an overview of the reasons for that. In addition to information on the technical aspects, the article also includes references to legal acts regulating issues related to biometrics.
