Opis:
W artykule rozważany jest problem budowania zaufania do artefaktów obliczeniowych typu AGI (ang. Artificial General Intelligence), z etycznego punktu widzenia określanych jako podmioty moralne explicite. W wyniku analizy opartej na badaniach literatury oraz przedstawieniu aktualnych trendów w rozwoju systemów AI wskazanych jest kilka warunków skonstruowania testów behawioralnych niezbędnych do sprawdzania poprawności ich działania z etycznego punktu widzenia. Przeprowadzenie takich testów powinno ułatwić procedury etycznej aprobaty systemów AGI zarówno na poziomie wytwórców, indywidualnego użytkownika, jak i jednostek certyfikujących.
The paper considers the problem of building trust in computational artefacts of the AGI (Artificial General Intelligence) type, which are defined from an ethical point of view as explicite moral agents. As a result of an analysis based on research of the literature and current trends in the development of AGI systems, several conditions have been presented for the construction of behavioural tests necessary to check the correctness of their functioning considered both from an ethical and social point of view. Conducting of such tests should simplify the market approval procedures of AGI systems at the level of manufacturers, the individual users and certification authorities.

Opis:
Since January 2021, Havila Kystruten has been one of two companies sailing the coastal route between Bergen and Kirkenes. This paper contains information on the new shipping company Havila Kystruten and their 2019 bid for a 10-year operational license to sail the coastal route. The government's tender documents for the new license specified that the vessels operating the route had to be low-emission vessels. This requirement was in line with the government's white paper on the reduction of emissions for commercial and fishing vessels sailing in Norwegian waters. Thus, companies bidding for the new license had to offer new ships with low emission characteristics or rebuild existing vessels to obtain the low emission requirements. Based on the offers, the government decided to split the operational license between two companies. One part was given to the company previously operating the route (Hurtigruten) and the other to the new company Havila Kystruten. While Hurtigruten would rebuild the engine systems on some of their existing vessels, Havila Kystruten would operate the route using new vessels with low emission signature. The design requirements for these vessels were given by Havila Kystruten to the ship designer, Havyard Design and Solutions (now HAVDesign). Some of the requirements are listed in section 4 below. The latter part of this paper investigates the manoeuvring performance of the new Havila Kystruten vessels, containing a summary of a Research Council of Norway funded innovation project on harsh weather ship handling during port operations. The Port of Trondheim was selected as a case study.

Opis:
Coronavirus (COVID-19) was detected at the end of 2019 and has since caused a worldwide pandemic. This virus is transferred airborne. In this study, an investigation was carried out of the ventilation strategies inside the isolation room based on exhaust air locations. To reduce the infection disease (COVID-19), due to the spreading of exhaled contaminants by humans in interior environments, five models for ventilation systems differing in the position of the outlet and inlet were used. This study aims to increase knowledge regarding the exhaled contaminant distribution under different environ-mental conditions (opening exhaust and negative pressure). The results showed a good agreement be-tween the computational results and the experimental data. Tracer gas CO2 was used to evaluate the air quality experimentally and computationally. The results showed that stable conditions are obtained inside the room at a negative pressure value above –1.5 Pa. The residence time of the infected airborne decreases when the pressure difference increases. The study revealed that the model with an air outlet opening installed behind the patient enabled avoiding the spread of infection in the room.

Opis:
A novel analytical model to predict fracture resistance of a quasi-brittle material, like wood, is presented. The model is based on a scaling parameter introduced into the non-local fracture theory to take into account the specimen size effect on the development of the damage zone. An expression for length of the critical process zone, which can be used in damage tolerant design of wooden structures is derived from this theory. The model is validated with mixedmode bending tests. A numerical analysis using cohesive elements is performed to understand the role of specimen size in the development of the damage zone. The analytical predictions of the fracture resistance and the critical process zone length for wood are compared with numerical results and experimental data available in the literature.

Opis:
The paper proposes a stand that can be used for the testing of propellers and rotors with diameters up to 2.4 m, whose areas of application encompass, inter alia, vertical takeoff and landing (VTOL) type multi-rotor drone systems. The presented solution allows for testing propellers in systems with electric motors. To a certain extent, it is possible to achieve an increase in the measuring range by changing electric motors, power supply systems and measuring sensors. The paper presents several solutions for test stands that can be applied in the testing of propeller parameters, and commercially available propellers have also been deployed in the testing routines. The paper briefly presents the concept of the stand and its design, as well as the principle of operation and structural calculations underlying its functioning, after which the numerical model of the test stand is explained. The article then demonstrates the particular results of the test stand model’s functioning using the EMRAX 188 electric motor and two propellers, namely a commercial Aerobat propeller and a composite propeller designed and manufactured at the Łukasiewicz - Institute of Aviation. Thus, the paper presents both the theoretical results that follow from the model and the results of experimental research.

Opis:
Within the frame of CTO’s standard procedure, a propeller open-water test is preceded by a reference measurement, which is taken for a reference propeller model (P356). The results of these measurements are assembled to conduct an open-water test uncertainty analysis. Additional material was gathered from open-water tests that were conducted throughout several research projects on the CP469 model, which is a model of the Nawigator XXI propeller. The latter is a controllable pitch propeller; its pitch was reset before each test repetition. Known procedures for the determination of the open-water test uncertainty do not allow one to extract the manufacture impact directly, without building many models. This factor was addressed with the use of lifting surface calculations. Under certain additional assumptions, these calculations were performed for 100 generic versions of each propeller’s geometry, which were generated by random deviations from the theoretical data within the limits of allowed tolerances. The results of the conducted analyses made it possible to extract separate factors, which were connected to the test’s repeatability, measurement bias and geometry tolerance.

Opis:
Designing products operating in harsh conditions is a challenging task. Years of experience, developed standards and good practices are crucial in achieving the intended result. The article shows a methodology for designing electronic systems based on the worst-case analysis (WCA) and comparing its outcomes with the experimental verification of an actual circuit through large-scale tests. The analysed diode-based semiconductor circuit is part of a temperature measuring system of industrial application. The objective of the design and analysis process is to achieve a reliable solution, which has all the required functionalities under actual, extreme operating conditions. The preliminary circuit design is developed using ideal components. The truth table, which represents customer requirements, is created to check the correct operation of the system. Simulation software, such as LTSpice, are used as the main tools to verify the correct functioning based on ideal or close-to-real component models. Next, based on the results of computer simulations, the WCA is conducted, considering all extreme (worst) operating environment parameters, such as, among others, ambient temperature or ageing. WCA results were verified through an experimental, large-scale measurement of the real system, with defined forward voltage as a function of the current flowing through the semiconductor at various ambient temperatures.

Opis:
The paper concerns the dimensional analysis of simple acoustic metamaterials and its experimental verification in a computer model. Due to their decreased thickness possible because of the thermoviscous losses and sound dispersion that occur in acoustic metamaterials, such structures are gaining popularity, both as sound absorbers and diffusers. This implies the need to find their equivalents to be used at scale - both for modeling interiors with metamaterials and developing more complicated structures. The paper discusses the dimensional analysis performed for a generalized unit cell of a metamaterial with a resonator. The dimensional analysis shows the need for scaling both the geometrical dimensions of the structure and the parameters of the medium - air. The dimensional analysis was derived based on the transfer matrix method and was proven correct with the finite element method model. The paper also discusses the consequences of neglecting the air criteria, which are impossible to be fulfilled. This opens the question of finding new criterial numbers allowing the correct reflection of acoustic metamaterials at scale.

The primary aim of the paper is the empirical vericfiation of the hypothesis on the convergence of real GDP per capita of the regions (NUTS-2) in Poland and the catch-up eefct of Eastern towards Western Poland. The empirical study is based on a relatively new analytical approach of Phillips and Sul convergence tests which consider signicfiant diefrences in technological advancement between regions. The results show that the convergence hypothesis was rejected in the group of all regions of Poland and the group of Western Poland regions. Convergence was conrfimed in the group of Eastern Poland regions. The strict catch-up eefct of the Eastern towards the Western Poland regions was not observed. Nevertheless, thirteen of seventeen regions of Poland were characterised by convergence but within distinct convergence clubs. The identicfiation of convergence clubs, however, was not determined by a sharp EastWest Poland dividing line.

Opis:
Stropy z płyt kanałowych pomimo ponad stu lat historii i miliarda metrów kwadratowych wykonanych tego typu konstrukcji w samej Europie nadal w pewnych aspektach projektowych budzą wątpliwości. W artykule przedstawiono wyniki wpływu krótkotrwałych i długotrwałych obciążeń na pełnoskalowy strop z płyt kanałowych o wymiarach 6,31 x 6,31 m. Badanie przeprowadzono pod niesymetrycznym obciążeniem grawitacyjnym, a ostatni pomiar wykonano po 665 dniach. Wykonana analiza obliczeniowa wykazała ponad trzykrotne przeszacowanie ugięć modelu płyty jednokierunkowej w odniesieniu do badań doświadczalnych. Przedstawiono uproszczone przestrzenne modele obliczeniowe, wraz z podaniem kryteriów stosowania. Badania i analizy wykazały, że powszechnie stosowana metoda obliczeniowa prowadzi do bardzo konserwatywnych wyników - nie oddając rzeczywistej charakterystyki pracy stropów z płyt kanałowych.
Despite over a hundred years of history and a billion square meters made in Europe alone, hollow-core slabs still raise doubts in some design aspects. The article presents the results of the short-term and long-term loads on a full-scale hollow-core slab with dimensions of 6.31 x 6.31 m. The test was carried out under an unsymmetrical gravity load, and the last measurement was carried out after 665 days. The computational analysis indicates over three times overestimated deflections of the one-way slab model compared to the experimental tests. Simplified spatial computational models are presented, along with application criteria. The research and the presented analyses have shown that the commonly used calculation method leads to very conservative results, without reflecting the actual performance characteristics of hollow-core slabs.

Opis:
A study of dolomite rock material failure using a simple small-scale blast setup is presented. Laboratory tests were conducted using disc specimens drilled with a borehole in the center. A detonation cord and a blasting cap were fitted inside the borehole to induce cracking and fracturing of the specimens. The specimens were inserted between two steel plates, which were compressed against the specimen using bolt screws. Prior to testing, the most suitable screw torque for constraining the vertical displacement of the specimen surfaces without compressing the specimen was selected based on numerical simulations. Then, the experimental tests with the blasting cap were simulated using the Johnson–Holmquist II (JH-2) material model, and the properties of the blasting cap were determined and verified in two special tests with a lead specimen. Possessing the validated model, the influence of specimen thickness on the cracking patterns was finally analyzed. This paper presents a relatively easy method for studying rock material behavior under blast loading and for validating the numerical and constitutive models used for rock simulations.

Opis:
Floating offshore wind turbines are easily affected by typhoons in the deep sea, which may cause serious damage to their structure. Therefore, it is necessary to study further the dynamic response of wind turbine structures under typhoons. This paper took the 5MW floating offshore wind turbine developed by the National Renewable Energy Laboratory (NREL) as the research object. Based on the motion theory of platforms in waves, a physical model with a scale ratio of 1:120 was established, and a hydraulic cradle was used to simulate the effect of waves on the turbines. The dynamic response characteristics of offshore wind turbines under typhoons are systematically studied. The research results clarified that the turbine structure is mainly affected by wave loads under typhoons, and its motion response reaches its maximum value under the action of extreme wave loads. The research results of this paper can provide reference value for the design of offshore wind turbine structures under typhoons.

The application of 3D printing technology has been relatively slow in the fashion industry. Both in the fashion industry and in 3D printing, the material used plays a very important role. In this direction, thermoplastic polyurethane (TPU) is one material that has started to grab the attention of researchers, producers, and customers. While many have studied 3D printing technology using thermoplastic polyurethane material in the fashion industry from different perspectives, fewer researchers have addressed the actual adoption of thermoplastic polyurethane based 3D printing in the fashion industry. Thus, the present research has been focused to propose an adoption model for thermoplastic polyurethane based 3D-printed fashion clothes. Factor analysis was conducted to find and analyse the most relevant factors. Further exploratory factor analysis was conducted to test the proposed model. The study proposed a model for adoption based on four factors: motivation to buy, customer attitude, and the challenges and benefits associated with the adoption of thermoplastic polyurethane based 3-D printed fashion clothes.

Opis:
This concept paper described the process of bridging the gaps in one of the methods for determining wheel over point (WOP). WOP is a marking made on charted courses to indicate a point at which a ship should change course. Identifying WOP is vital to avoid the vessel overshooting the planned track. One method for determining WOP is the advanced transfer technique. However, two issues were identified while reviewing this technique. Therefore, an improved mathematical model could be developed to overcome these problems. A manoeuvring analysis using a ship simulator will be performed to test the developed mathematical model's efficacy. The data obtained from the simulation study can be validated further by its adherence to the cross track limit, reduction in percentage change, and using IBM SPSS for the Mann-Whitney U test. The developed mathematical model is expectantly capable of producing a better track-keeping function and suitable for use onboard a cargo ship. The mathematical model also could be implemented as an algorithm in the Electronic Chart Display and Information System to help navigators make more efficient course changes.

This study aims to explain the association between the quarterly data obtained over the period 2007: Q2–2020: Q3 for Turkey and the countercyclical capital buffer (CCyB) proposed within the framework of Basel III with banking performance and risk indicators. For this purpose the association among the variables was analyzed using the ARDL model and by performing the Toda Yamamoto (T-Y) causality test. According to the analysis results, it was determined that the CCyB has a statistically significant and positive relationship with the capital adequacy indicators of the banks in the long-run, however, it has a statistically significant and negative relationship with the asset quality risk and currency risk indicators. In the short-run it was determined that the CCyB has a statistically significant and positive relationship with the capital adequacy, profitability and liquidity indicators and similar to the long-term relationship, it has a statistically significant and negative relationship with the asset quality risk and exchange rate risk indicators. According to the causality test results, a statistically significant and unilateral causality running from the indicators of capital adequacy, asset quality and exchange rate risk to the CCyB was detected. The obtained estimation results indicate that the CCyB can be increased by policymakers during the periods when the performance indicators of the banking sector rise, whereas can be decreased by policymakers during the periods when the risk indicators of the sector rise. Furthermore, the results of the study asserted that the CCyB was an appropriate instrument for mitigating the macroeconomic and systemic risks for Turkey.
