  • Application of the Flipped Learning Methodology at a Business Process Modelling Course – A Case Study
    • Marzena Grzesiak
    • Marek Moszyński
    2024

    Flipped learning has been known for a long time, but its modern use dates back to 2012, with the publication of Bergmann and Saams. In the last decade, it has become an increasingly popular learning method. Every year, the number of publications on implementing flipped learning experiments is growing, just as the amount of research on the effectiveness of this educational method. The aim of the article is to analyze the possibilities of using the flip blended methodology for teaching in the area of BPM. The pilot flipped learning course was implemented as a Business Process Modeling course addressed to Gda´nsk University of Technology students and the feedback from the course participants has been collected. Among the pre-class resources, PDF files (containing descriptions and screenshots of the relevant issue) and videos were most often used. The aim of this research was to gather students’ opinions on flipped learning and, based on these insights, to design well-founded changes. Many students did not point out the disadvantages of flipped learning. Still, some believe this method may be less effective than the traditional one. Based on the research results, a course redesign will be prepared according to the flipped learning framework.

    2024 CURRENT TOPICS IN MEDICINAL CHEMISTRY

    Several classes of compounds are applied in clinics due to their immunosuppressive properties in transplantology and the treatment of autoimmune diseases. Derivatives of mycophe-nolic acid, corticosteroids and chemotherapeutics bearing heterocyclic moieties like methotrexate, azathioprine, mizoribine, and ruxolitinib are active substances with investigated mechanisms of action. However, improved synthetic approaches of known drugs and novel derivatives are still being reported to attempt better accessibility and therapeutic properties. In this review article, we present the synthesis of the designed chemical structures based on recent literature reports con-cerning novel compounds as promising immunosuppressive drugs. Moreover, some of the dis-cussed derivers revealed also other types of activities with prospective medicinal potential.

    • Marek Tatara
    • Zdzisław Kowalczuk
    2024 Pełny tekst International Journal of Applied Mathematics and Computer Science

    The article presents a comprehensive quantitative comparison of four analytical models that, in different ways, describe the flow process in transmission pipelines necessary in the task of detecting and isolating leaks. First, the analyzed models are briefly presented. Then, a novel model comparison framework was introduced along with a methodology for generating data and assessing diagnostic effectiveness. The study presents basic assumptions, experimental conditions and considered scenarios. Finally, the quality of the model-based diagnostic estimators is assessed, focusing on their bias, standard deviation, and computational complexity. Here, several optimality criteria are used as detailed indicators of the quality and performance of the estimators in a multi-criteria Pareto optimality assessment.

    2024 COMPUTERS & OPERATIONS RESEARCH

    The problem of scheduling jobs on parallel machines (identical, uniform, or unrelated), under incompatibility relation modeled as a block graph, under the makespan optimality criterion, is considered in this paper. No two jobs that are in the relation (equivalently in the same block) may be scheduled on the same machine in this model. The presented model stems from a well-established line of research combining scheduling theory with methods relevant to graph coloring. Recently, cluster graphs and their extensions like block graphs were given additional attention. We complement hardness results provided by other researchers for block graphs by providing approximation algorithms. In particular, we provide a 2-approximation algorithm for and a PTAS for the case when the jobs are unit time in addition. In the case of uniform machines, we analyze two cases. The first one is when the number of blocks is bounded, i.e. . For this case, we provide a PTAS, improving upon results presented by D. Page and R. Solis-Oba. The improvement is two-fold: we allow richer graph structure, and we allow the number of machine speeds to be part of the input. Due to strong NP-hardness of , the result establishes the approximation status of . The PTAS might be of independent interest because the problem is tightly related to the NUMERICAL -DIMENSIONAL MATCHING WITH TARGET SUMS problem. The second case that we analyze is when the number of blocks is arbitrary, but the number of cut-vertices is bounded and jobs are of unit time. In this case, we present an exact algorithm. In addition, we present an FPTAS for graphs with bounded treewidth and a bounded number of unrelated machines. The paper ends with extensive tests of the selected algorithms.

    Arabinoxylans (AXs) are compounds with high nutritional value and applicability, including prebiotics or supplementary ingredients, in food manufacturing industries. Unfortunately, the recovery of AXs may require advanced separation and integrated strategies. Here, an analysis of the emerging techniques to extract AXs from cereals and their by-products is discussed. This review covers distinct methods implemented over the last 2–3 years, identifying that the type of method, extraction source, AX physicochemical properties and pre-treatment conditions are the main factors influencing the recovery yield. Alkaline extraction is among the most used methods nowadays, mostly due to its simplicity and high recovery yield. Concurrently, recovered AXs applied in food applications is timely reviewed, such as potential bread ingredient, prebiotic and as a wall material for probiotic encapsulation, in beer and non-alcoholic beverage manufacturing, complementary ingredient in bakery products and cookies, improvers in Chinese noodles, 3D food printing and designing of nanostructures for delivery platforms.

    • Remigiusz Martyniak
    • Bartosz Czaplewski
    2024

    This paper investigates the impact of various modifications introduced to current state-of-the-art Convolutional Neural Network (CNN) architectures specifically designed for the steganalysis of digital images. Usage of deep learning methods has consistently demonstrated improved results in this field over the past few years, primarily due to the development of newer architectures with higher classification accuracy compared to their predecessors. Despite the advances made, further improvements are desired to achieve even better performance in this field. The conducted experiments provide insights into how each modification affects the classification accuracy of the architectures, which is a measure of their ability to distinguish between stego and cover images. Based on the obtained results, potential enhancements are identified that future CNN designs could adopt to achieve higher accuracy while minimizing their complexity compared to current architectures. The impact of modifications on each model’s performance has been found to vary depending on the tested architecture and the steganography embedding method used.

    2024 Thinking Skills and Creativity

    Open Government Data (OGD) has been considered as a potent instrument for value creation and innovation by a range of stakeholders. Given that individual ingenuity is a function of individual and environmental factors, it is important to understand how the OGD adoption and usage is a factor of creative performance behaviors (CPB), viz., Problem Identification (PI), Information Search (IS), Idea Generation (IG) and Idea Promotion (IP) as well as creative self-efficacy (CSE). Invoking the adapted Unified Theory of Acceptance and Use of Technology (UTAUT) constructs alongside the moderating effects of CPB and CSE constructs and also gender, the present study seeks to underline the behavioural intention towards OGD adoption and usage among 362 undergraduate and postgraduate university students in India. Findings show that there are gender differences across the CPB and CSE constructs. The study’s contribution lies in furthering our understanding of OGD adoption and use with creativity literature

    This chapter presents a summary of the description and preliminary results of the use case related to the implementation of artificial intelligence tools in the emerging technology called wireless avionics intra-communications (WAICs). WAICs aims to replace some of the cable buses of modern aircraft. This replacement of infrastructure leads to: (1) complexity reduction of future airplanes, (2) creation of innovative services where wireless links are more flexible than wireline links, and mainly (3) a considerable weight reduction, which in turn leads to fuel consumption efficiency, increase of payload, as well as range extension. Therefore, WAICs is expected to have a large impact on the aeronautics industry, propelling a new generation of greener, more efficient, and less expensive aeronautical services. However, there are still several reliability, trust, interoperability and latency issues that need to be addressed before this technology becomes commercial. It is expected that AI will boost the applicability of this technology, contributing to the realization of the concept of “fly-by-wireless”.

    2024 Pełny tekst Global Journal of Engineering Education

    The rapid advancement of artificial intelligence (AI) technologies has introduced new possibilities and challenges in design education. This article explores the need for changes and adaptations in the teaching process of design as AI-related technologies, based on image generation, transform the creative process and offer novel opportunities. In a research-by-design studio in an architectural faculty in Poland, students who utilised AI tools achieved more innovative and pioneering results than those designed with traditional tools. Based on these results, three alternative methods of working with AI tools were identified. In the semi-traditional approach, AI-generated images served for inspirational purposes solely. In the hybrid system, students integrated fragments of these images into their own urban decisions. Finally, in the hybrid-interactive approach, students used the higher-order loops in computer-human interaction to achieve more site-specific results. The research underscores the vast potential of AI integration, using image generation models in reshaping architectural design methodologies based on best practice.

    2024 Journal of Fungi

    Onychomycosis is a common fungal nail infection that is difficult to diagnose due to its similarity to other nail conditions. Accurate identification is essential for effective treatment. The current gold standard methods include microscopic examination with potassium hydroxide, fungal cultures, and Periodic acid-Schiff biopsy staining. These conventional techniques, however, suffer from high turnover times, variable sensitivity, reliance on human interpretation, and costs. This study examines the potential of integrating AI (artificial intelligence) with visualization tools like dermoscopy and microscopy to improve the accuracy and efficiency of onychomycosis diagnosis. AI algorithms can further improve the interpretation of these images. The review includes 14 studies from PubMed and IEEE databases published between 2010 and 2024, involving clinical and dermoscopic pictures, histopathology slides, and KOH microscopic images. Data extracted include study type, sample size, image assessment model, AI algorithms, test performance, and comparison with clinical diagnostics. Most studies show that AI models achieve an accuracy comparable to or better than clinicians, suggesting a promising role for AI in diagnosing onychomycosis. Nevertheless, the niche nature of the topic indicates a need for further research.

    The objective of this paper is to provide the fatigue life of riveted joints in AA2024 aluminum alloy plates and optimization of riveted joints parameters. At first, the fatigue life of the riveted joints in AA2024 aluminum alloy plates is obtained by experimental tests. Then, an artificial neural network is applied to estimate the fatigue life of riveted lap joints based on the number of lateral and longitudinal holes, punch pressure, gap between the edge of hole and rivet, rivet shank diameter, and rivet shank length. Also, meta heuristic optimization algorithm is applied to calculate the riveting process parameters. Finally, sensitivity analysis is used to obtain the influence of parameters affecting the riveting process on the fatigue life.


  • Asphalt Overlay Enhancement with Fatigue High-Performing Multiaxial Geocomposite
    • Piotr Jaskuła
    • Michał Golos
    2024

    The use of gecomposite incorporating multiaxial geogrid and non-woven fabric of high bitumen retention in asphalt overlays results in the increase of life of the designed pavement structure. Such an approach can offer an opportunity to increase the fatigue life (higher traffic capacity) without the need to increase asphalt overlay thickness or to reduce the thickness of asphalt overlay without reduction of pavement life eventually. This concept results in both economic and environmental benefits. This paper presents the laboratory testing results of the fatigue life of double-layered asphalt specimens with geocomposite used directly in the pavement structure fatigue life calculations. Fatigue testing was performed in the scheme of four-point bending tests (4PB) of large beams in the controlled strain mode – both for reinforced and control specimens. Based on the results obtained, one can conclude that the rated multiaxial geocomposite has a clear and positive effect on asphalt overlay performance and thus has an evident potential to extend the asphalt pavement fatigue life. This paper also presents a slightly modified concept of the Mechanistic-Empirical pavement design method based on fatigue improving factors derived from the laboratory test investigation, allowing reinforcement benefits to be implemented into the design process. Finally, an example of the calculation of reconstructed asphalt pavement with the enhancement of the asphalt overlay reinforced by geocomposite is also presented.

    2024 Archives of Civil Engineering

    The paper briefly describes modern method assessment of the pavement structure based on the simplified viscoelastic continuum damage (S-VECD) model. The method was used to compare two types of pavement structures. There were analysed classical cstructures with asphalt concretes with neat bitumen and innovative one- or two layered structures with SMA 16 with highly polymer modified bitumen (HiMA). Pavement structures using SMA 16 are especially recommended for local roads, thus two traÿc categories were analysed – light and medium. Furthermore, due to specific properties of layers with HiMA, for each variant two di˙erent types of improved sub-base were checked. The examples presented, despite reduced thickness of asphalt layers, structures with SMA 16 HiMA are much more resistant to fatigue than classic structures with asphalt concretes with neat bitumen. The results of the research confirm that it is possible to develop innovative structures with materials with above standard properties. New materials both with new arrangement of layers can bring a lot of advantages especially in the areas of sustainable development, costs reducing and improving properties of asphalt pavements.


  • Assessing climate change threats and urbanization impacts on surface runoff in Gdańsk (Poland): insights from remote sensing, machine learning and hydrological modeling

    2024 Pełny tekst STOCHASTIC ENVIRONMENTAL RESEARCH AND RISK ASSESSMENT

    This study investigates the impacts of Land Use/Land Cover (LULC) changes and climate change on surface runoff in Gdańsk, Poland, which is crucial for local LULC planning and urban flood risk management. The analysis employs two primary methodologies: remote sensing and hydrological modeling. Remote sensing was conducted using Google Earth Engine and Land Change Modeler in IDRISI Terrset software to analyze historical (1985–2022) and future (2050–2100) LULC. Hydrological modeling was performed using the Natural Resources Conservation Service curve number method to assess the overall impact of LULC changes on Gdańsk’s hydrology at the local scale. The Orunia basin, a critical area due to intensive LULC development, was selected for detailed hydrological analysis using the Hydrologic Modeling System (HEC-HMS). The analysis encompassed three scenarios: LULC changes, climate change, and combined LULC and cli- mate change effects. The LULC analysis revealed a marked increase in urban area, a shift in forest and vegetation cover, and a reduction in agricultural land. HEC-HMS simulations showed an increase in the runoff coefficient across selected decades, which was attributed to the combined effect of LULC and climate change. The projected increases under the Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 scenarios for 2050 and 2100 are projected to surpass those observed during the baseline period. The findings highlight that the synergistic effects of LULC and climate change have a more significant impact on Gdańsk’s hydrology at both local and basin scales than their separate effects. These insights into LULC shifts and urban hydrological responses hold implications for sustainable urban planning and effective flood risk management in Gdańsk and similar urban settings.

    2024 SUSTAINABLE DEVELOPMENT

    This research paper delves into the captivating realm of sustainable development, specifically focusing on assessing the degree of implementation of sustainable development goal 7 (SDG7) and its intricate relationship with social, economic and ecological factors within European Union (EU) countries. By comprehensively unravelling the interplay between SDG7 and these multifaceted factors, this study provides invaluable insights into the ongoing sustainable energy revolution within the EU. To verify the research hypotheses, composite indicators (CI) were estimated for SDG7 and selected groups of indicators, employing a methodology grounded in sensitivity analysis. Our findings notably highlight the distinct significance of ecological factors in driving the development of clean energy systems. In contrast, the data did not support our hypothesis, which posited a significant relationship between economic factors and the implementation of SDG7. This evolving perspective underscores the growing recognition of the fundamental role that ecological factors play in shaping our sustainable energy future. Consequently, as we prioritise preserving and conserving our environment, the need to balance economic prosperity with environmental well-being becomes increasingly evident.

    Hydrodynamic cavitation (HC) is widely acknowledged as a promising green approach for enhancing various production and waste management processes, such as water treatment, sludge pretreatment, lignocellulosic biomass (LCB) pretreatment, emulsification, and food processing. Despite demonstrating superior industrialization potential compared with other emerging technologies such as ultrasound and microwave, the widespread commercial adoption of HC remained limited even after three decades of development. This review aims to assess the current distance from industrialization and promote the advancement of HC by summarizing recent progress in the pilot or full-scale applications, particularly in biodiesel synthesis, water treatment, and the pretreatment of sludge and LCB. Special attention is given to treatment capacity and economic efficiency.
