Flood protection of the non-urban area
Get PDFDue to global warming, the risk of floods is constantly increasing due to the drying up of the soil, followed by more intense rain showers and storms. Therefore, it is essential to pay more attention to this topic now. The article deals with the design of flood protection in the municipality. A flood control measure is proposed for each type of slope of the soil relief in which the municipality is located. Based on the proposed measures, the article aims to minimize the level of flood risk to the lowest possible level with the use of flood protection aimed at the non-urban area of the municipality. The proposed measures are intended not only for smaller municipalities but also for cities.Department of Security Engineering, Faculty of Applied Informatics; Univerzita Tomáše Bati ve Zlíně, (IGA/FAI/2023/001
Developing the concept of task substitution and transformation by defining own equivalences
Get PDFThe presented article is dedicated to a new way of teaching substitution in algebra. In order to effectively master the subject matter, it is necessary for students to perceive the equal sign equivalently, to learn to manipulate expressions as objects, and to perceive and use transformations based on defining their own equivalences. According to the results of several researches, these changes do not occur automatically, and the neglect of their development leads to students' insufficient adoption of substitution. The submitted contribution presents a new way of teaching substitution, the stages of which support the gradual development of the necessary competences of students, so that substitution becomes part of their computing apparatus. The effectiveness of the mentioned method of teaching substitution was also verified experimentally. By conducting a pedagogical experiment, it was confirmed that the application of the substitution teaching method developed by us led to more frequent use of substitution by students from the experimental group (47 students) compared to students from the control group (82 students) who learned substitution in the usual way. It emerged from the interview with experimental group students that they considered the proposed method suitable and that it encouraged them to learn substitution in depth.Ministry of Education, Science, Research and Sport; Agentúra na Podporu Výskumu a Vývoja, APVV, (APVV-14-0446

Achieving market performance via Industry 4.0 enabled dynamic marketing capability, sustainable human resource management, and circular product design
No full textBusiness-to-business (B2B) firms are striving to sustain market growth and share in dynamic marketing environment with an increasing need to protect natural resources in era of sustainability and industry 4.0. Although many firms have adapted industry 4.0 technologies, circular economy and sustainability practices in their business activities, but to sustain market growth is still a challenge. They need dynamic capabilities to face the current dynamic market instead of just resources and their capabilities. This study empirically examines whether Industry 4.0-enabled dynamic marketing capabilities and sustainable human resource management (SHRM) can enable firms to implement circular product design strategies and further improve market performance. The proposed framework is based on a dynamic capability view (DCV) and tested by structural equation modeling using survey data from 424 Indian B2B manufacturing firms. The findings show that SHRM promotes Industry 4.0-enabled dynamic marketing capabilities (IDMC); IDMC and SHRM both support implementation of circular product design strategies. Circular product design is supposed to facilitate IDMC to expand market performance. But, IDMC alone is also enough to significantly enhance market performance, despite the combined positive effect of circular product design and SHRM on market performance. These findings contribute to better understanding on what type of dynamic capabilities of organizational resources should be developed and utilized to improve market performance. The study helps firms to develop dynamic marketing capabilities such as circular product design strategies, SHRM and IDMC for helping them in improving market performance while also growing sustainably

Comparing stacking ensemble and deep learning for software project effort estimation
No full textThis study focuses on improving the accuracy of effort estimation by employing ensemble, deep learning, and transfer learning techniques. An ensemble approach is utilized, incorporating XGBoost, Random Forest, and Histogram Gradient Boost as generators to enhance predictive capabilities. The performance of the ensemble method is compared against both the deep learning approach and the PFA-IFPUG technique. Statistical criteria including MAE, SA, MMRE, PRED(0.25), MBRE, MIBRE, and relevant information related to MMRE and PRED(0.25) are employed for evaluation. The results demonstrate that combining regression models with Random Forest as the final regressor and XGBoost and Histogram Gradient Boost as prior generators yields more accurate effort estimation than other combinations. Furthermore, the findings highlight the potential of transfer learning in the deep learning method, which exhibits superior performance over the ensemble approach. This approach leverages pre-trained models and continuously improves performance by training on new datasets, providing valuable insights for cross-company and cross-time effort estimation problems. The ISBSG dataset is used to build the pre-trained model, and the inductive transfer learning approach is verified based on the Desharnais, Albrecht, Kitchenham, and China datasets. The study underscores the significance of transfer learning and the integration of domain-specific knowledge from existing models to enhance the performance of new models, thereby improving accuracy, reducing errors, and enhancing predictive capabilities in effort estimation.

Investigating the antecedents of ecotourism and destination loyalty among Vietnamese tourists: An expectation–confirmation perspective
No full textWhat makes tourists revisit a particular destination? Contemporary researchers have approached this problem through the lenses of various operant conditioning models. The current study explores the dimensions of ecotourism and destination loyalty anchoring on the expectation-confirmation theory. The findings confirm that factors such as destination image, tourist satisfaction and tourist experience significantly predict destination and ecotourism loyalty. The investigation first employs a confirmative factor analysis (CFA) model with a marker to inspect correlations among the latent variables. After the constructs are validated through the CFA procedure, a series of hierarchical regressions are introduced to test the hypotheses formulated. The empirical observations approve of all direct and indirect pathways in the structural equation model. For the purpose of the study, 522 Vietnamese tourists who travelled to the Czech Republic for tourism were recruited. The examination has profound marketing implications for ecotourism businesses and DMOs to improve their delivery models.Internal Grant Agency of FaME, (FSR FORD 5–6/2022–23/FaME/006, IGA/FaME/2022/012
Computational analysis of indoor thermal comfort in a terraced family house with thermal insulation
Get PDFComputer simulations are used to assess the impact of thermal insulation on the transfer of heat and moisture in the exterior walls of residential buildings. The effects of internal and external thermal insulation on a room in a terraced family house are compared using the COMSOL Multiphysics software package, evaluating the influence of the placement of expanded polystyrene thermal insulation on the distribution of heat and moisture in the external wall while monitoring the indoor air temperature during the heating and cooling regimes. The internal thermal insulation is more efficient in terms of room heating, while the external insulation is preferable in reducing the risk of the condensation water vapor within the wall. The efficiency of heating the room to 20°C increased by 12% when internal thermal insulation was added to the walls, compared to heating without insulation. The maximum value of relative humidity in the critical wall section decreased by 10% when external thermal insulation was added. Implementing internal thermal insulation needs the right choice of insulation material and its installation to prevent air leakage. The results suggest that the proper selection of the placement of the thermal insulation is critical for optimizing the thermal performance and reducing moisture-related problems in residential buildings.

Chaotic attractors of discrete dynamical systems used in the core of evolutionary algorithms: state of art and perspectives
Get PDFThis paper delves into the intersection between discrete dynamical systems and bio-inspired metaheuristic algorithms. Chaos, an inherent phenomenon manifested by both continuous and discrete dynamic nonlinear systems has become an essential component of engineering design. This study examines the relationship between chaos and bio-inspired metaheuristic algorithms from two distinct angles: the presence of chaos within the realm of algorithms, and the application of bio-inspired algorithms for the identification, control, or synthesis of complex systems. Furthermore, this paper offers an in-depth exploration of the interplay between metaheuristics and complex nonlinear dynamics, including potential avenues for future research. The presented simulation studies, along with the design of objective functions for optimization and the implementation of metaheuristics, serve as a valuable foundation for subsequent experiments involving discrete nonlinear systems and complex systems with time delays. Such systems may benefit from multiparametric or multicriteria optimization approaches, paving the way for novel advancements in the field.SGS [SP2023/050]; VSB-Technical University of Ostrava, Czech Republic; Grant Agency of Czech Republic (GACR) [GF21-45465L]; Faculty of Applied Informatics, Tomas Bata University in Zli
Volume change measurements using 2D DIC system
Get PDFThe presented study focuses on measuring volume changes in elastomeric materials using digital image correlation (DIC), specifically the 2D DIC universal system and the 2D DIC video-extensometer directly implemented to the universal testing machine. Optical measurement methods were applied in two-dimensional (2D) configurations during the mechanical testing of dumbbell-shaped test specimens under uniaxial tension. The measured data were used to determine the dependencies of the bulk modulus and Poisson's ratio on the strain. The dependencies obtained by both methods correspond to the model behavior of rubber-like materials. Compared to the 2D DIC implemented video-extensometer, the 2D DIC universal system provides a tool for measuring transverse and longitudinal strain, and a wide range of post-processing options, including change of the input parameters, settings, or calculation relations.TBU in Zlin [IGA/FT/2023/004
