Strategies for comparison of modern probabilistic seismic hazard models and insights from the Germany and France border region

Published: November 2024

Abstract. The latest generation of national and regional probabilistic seismic hazard assessments (PSHAs) in Europe presents stakeholders with multiple representations of the hazard in many regions. This raises the question of why and by how much seismic hazard estimates between two or more models differ, not only where models overlap geographically but also where new models update existing ones. As modern PSHA incorporates increasingly complex analysis of epistemic uncertainty, the resulting hazard is represented not as a single value or spectrum but rather as probability distribution. Focusing on recent PSHA models for France and Germany, alongside the 2020 European Seismic Hazard Model, we explore the differences in model components and highlight the challenges and strategy for harmonising the different models into a common PSHA calculation software. We then quantify the differences in the source model and seismic hazard probability distributions using metrics based on information theory, illustrating their application to the Upper Rhine Graben region. Our analyses reveal the spatial variation in and complexity of model differences when viewed as probability distributions and highlight the need for more detailed transparency and replicability of the models when used as a basis for decision-making and engineering design.
A robust numerical method for the generation and propagation of periodic finite-amplitude internal waves in natural waters using high-accuracy simulations

Published: November 2024

Abstract. The design and implementation of boundary conditions for the robust generation and simulation of periodic finite-amplitude internal waves is examined in a quasi two-layer continuous stratification using a spectral-element-method-based incompressible flow solver. The commonly used Eulerian approach develops spurious, and potentially catastrophic small-scale numerical features near the wave-generating boundary in a non-linear stratification when the parameter A/(δc) is sufficiently larger than unity; A and δ are measures of the maximum wave-induced vertical velocity and pycnocline thickness, respectively, and c is the linear wave propagation speed. To this end, an Euler–Lagrange approach is developed and implemented to generate robust high-amplitude periodic deep-water internal waves. Central to this approach is to take into account the wave-induced (isopycnal) displacement of the pycnocline in both the vertical and (effectively) upstream directions. With amplitudes not restricted by the limits of linear theory, the Euler–Lagrange-generated waves maintain their structural integrity as they propagate away from the source. The advantages of the high-accuracy numerical method, whose minimal numerical dissipation cannot damp the above near-source spurious numerical features of the purely Eulerian case, can still be preserved and leveraged further along the wave propagation path through the robust reproduction of the non-linear adjustments of the waveform. The near- and far-source robustness of the optimized Euler–Lagrange approach is demonstrated for finite-amplitude waves in a sharp quasi two-layer continuous stratification representative of seasonally stratified lakes. The findings of this study provide an enabling framework for two-dimensional simulations of internal swash zones driven by well-developed non-linear internal waves and, ultimately, the accompanying turbulence-resolving three-dimensional simulations.

Authors: Luthra Kaushik , Mays Anna , Atungulu Griffiths
Published: November 2024

The aim of this review paper is to document the role of post-harvest rice cooling in ensuring the safe storage of rice, given the ongoing increase in rice production. The United States exports substantial quantities of rice, with milled and rough rice being the primary exports. The industry has experienced growth, propelled by rising demand, a diverse population, and international trade. Effective storage of harvested rice is essential for year-round utilization, and the USA utilizes both on-farm and off-farm in-bin storage methods equipped with features like moisture control, pest management, and temperature regulation. The adoption of rice cooling technology for storage emerges as a solution to accelerate drying, prolong shelf life, and improve overall quality. Despite challenges such as upfront costs and energy requirements, cooling technology offers benefits for both short-term and long-term storage. Integrating cooling models into mathematical simulations becomes crucial for optimizing storage conditions. Research opportunities in post-harvest rice cooling focus on energy-efficient technologies, smart sensors, modern storage structures, microbial control methods, and economic evaluations. Future trends encompass automation, intelligent monitoring, climate-controlled storage, sustainability measures, and technological integration to enhance the efficiency and security of rice storage facilities in the USA.

AUTOMATIC PATH PROGRAMMING FOR THE MANUFACTURING OF SHEET METAL COMPONENTS USING INCREMENTAL FORMING TECHNOLOGY
Authors: Ortiz Edesa Mikel , PENALVA OSCOZ MARILUZ , ORTIZ DE ZARATE MAITE , Yang Hai , CHEN XIANDONG , Liu Xiaojun
Published: November 2024

Asymmetric Incremental Sheet Forming (AISF) is an unconventional forming technology that involves localized and progressive plastic deformation of a sheet using a tool, typically a punch, following a continuous and numerically controlled path. Due to its specific characteristics and advantages, such as flexibility and relatively low implementation cost, it is considered a technology with great potential for competitively producing small series of sheet metal components. However, there are still some challenges, such as the lack of specific CAM tools for this technology, which has hindered its industrialization.
Although the process may appear simple, with a 3D path sufficient to transform the original flat sheet into the final part, it has been observed that the manufacturing of real designs requires extensive knowledge of the technology to choose the appropriate path based on the target geometry. In this regard, this study presents a new solution developed by Tecnalia that incorporates expert process knowledge and enables automatic programming of Incremental Forming paths. Specifically, the solution allows programming paths aimed at manufacturing different geometric features commonly found in sheet metal components. This development has been validated through the manufacturing of several parts in a robotic cell implemented at Southeast University in Nanjing.

Published: November 2024

In this work experimental results are presented concerning the auxetic behavior of a crumpled metamaterial manufactured with aluminum foil, so far such experimental evidence has not been reported by other authors. Thus, 2D digital image correlation (DIC) was used to make full field measurements of longitudinal and transverse strains on the surface of crumpled aluminum specimens under axial compression; it was no possible to use conventional methods on the measurements of strains, such as strain gages or extensometers, due to the irregular topography on the surface of the specimens. The obtained results exhibit the auxetic nature of the aluminum crumpled material, with Poisson´s ratio values that vary from ?=-0.17 to ?=-0.02 for relative densities in the range ?_r=0.07 to ?_r=0.21.

Keywords: Auxetic, Digital Image Correlation, Crumpled material, Poisson, Computer vision system.

Published: November 2024

Progress towards a decarbonized economy is dependent on the development of energy storage devices enabling the deployment of new strategies in the transport and energy sectors. Lithium-Ion Batteries (LIBs) play a key role in facilitating the shift from fossil fuels to renewables based on ubiquitous sources of decentralized energy. However, the rapidly increasing demand for batteries has generated environmental concerns regarding recycling, and raw materials depletion and exhaustion. Moreover, the level of extraction and processing of battery raw materials from local resources is almost negligible, inducing geopolitical concerns regarding potential threats to production and the stability of local manufactures. Finally, the storage and processing of hazardous wastes remains a difficult challenge in the circular economy concept. Recycling, therefore, is beneficial to the environment and has a high economic value via strengthening local supply chains.
This work presents an alternative, comprehensive, and holistic review of LIB recycling technologies; from traditional metallurgy strategies to innovative, direct recycling methods and pioneering in-production and design-for-recycling approaches. It identifies new directions for making recycling efficient and techno-economically profitable and sustainable - including the vital role of robotics, artificial intelligence, and machine learning.

Published: November 2024

A relevant evaluation index system was established in this study for the objective measurement of emergency management capability for urban flood disasters based on the four stages of emergency response, namely, “prevention, early warning, response, and recovery.” The weight distribution of different evaluation indices was calculated by using the CRITIC method, which generated an evaluation cloud and a result cloud based on the cloud model. A case study on the emergency management of Zhengzhou City in Henan Province of the “7.20 Flood Disaster” was conducted, and the evaluation results were displayed intuitively as the digital features of the cloud model and in the computational cloud diagrams. The evaluation results of the emergency management capability of Zhengzhou City for the “7.20 Flood Disaster” were obtained, and a new direction for emergency management capability improvement was proposed based on a capability enhancement priority matrix. Results showed that Zhengzhou City exhibited only the “simple level - system management mode” in coping with the “7.20 Flood Disaster.” Zhengzhou City can improve its emergency management capability against flood disasters by improving the reliability of its monitoring and communication systems, the effectiveness of its publicity and education measures, and the timeliness of its provision of postdisaster information statistics and reports. The conclusions disclose a new direction for the scientific judgment of emergency management capability for flood disasters and the formulation of capability enhancement strategies.

Рассмотрены проблемы нормирования шероховатости поверхности валов под армированную резиновую манжету. Выявлено, что уменьшение шероховатости поверхности вала, приводит к повышенным утечкам, а при ее увеличении резко возрастает износ манжеты. Показано, что относительная опорная длина профиля будет влиять на износ манжеты. С целью повышения долговечности уплотнительного узла рекомендовано нормировать шероховатость поверхности не только в заданном диапазоне, но и учитывать расположение неровностей, относительную опорную длину профиля, которая может быть обеспечена поверхностно-пластическим деформированием в виде обкати роликами или шариками.

The problems of standardizing the surface roughness of shafts for reinforced rubber seals are considered. It has been revealed that a decrease in the roughness of the shaft surface leads to increased leakage, and with its increase, seal wear increases sharply. It has been shown that the relative support length of the profile will influence seal wear. In order to increase the durability of the sealing unit, it is recommended to normalize the surface roughness not only within a given range, but also to take into account the location of irregularities and the relative supporting length of the profile, which can be provided by surface-plastic deformation in the form of rolling with rollers or balls.

Implantation of nanoparticles into materials using a laser shock wave (INLSW) is a new method of hardening the surfaces of light metals and alloys. The hardening is based on a combination of plastic deformation caused by the well-known laser shock processing technology (LSP) with high mechanical characteristics of solid-phase nanoparticles. In this paper, we study the specific relationships between the hardening mechanisms and the properties of the surface treated with INLSW technology. It has been established that the hardening effect when using the INLSW technology is mainly achieved by two factors: the gradient microstructure caused by plastic deformation and the gradient distribution over the depth of the implanted SiC nanoparticles. It has been established that the hardening effect in the process of injection molding in gradient-reinforced layers is carried out by three competing hardening mechanisms, namely: dispersion hardening with SiC nanoparticles, hardening by grinding grains and dislocation hardening. The contribution of each hardening mechanism to the overall hardening has been studied using a modified Klein computational model.

Во введении обоснована актуальность исследований. Цель работы – с позиций механики микроконтактного взаимодействия частиц с лопастью проанализировать параметры напряженно-деформированного состояния в зоне фрикционного скользящего контакта и выработать рекомендации по выбору материала лопасти. Методика исследований включала математическое моделирование параметров фрикционного скользящего контакта частиц с лопастью ротора. Принята расчетная схема для контакта упругой сферической частицы абразива, прижимаемой силой Кориолиса к лопасти из упругопластического материала. Максимальное контактное давление для взаимодействия сферы с упругим полупространством рассчитано по формуле Герца. Учитывали, что при взаимодействии твердых частиц с поверхностью детали из упругопластического материала возможны три следующих вида деформирования: идеально упругое, стесненное упругопластическое и свободное упругопластическое деформирование с деформационным упрочнением. В основной части работы выполнен анализ и приведена общая характеристика механизмов и закономерностей газоабразивного изнашивания разгонных лопастей типовых конструкций турбомашин. Получены расчетные зависимости, описывающие распределение возникающих контактных напряжений по длине радиальных лопастей центробежных устройств.
Произведена расчетная оценка этих напряжений для средней и выходной частей лопасти на примере контакта радиальных стальных лопастей с типовыми представителями абразивных частиц – кварца и корунда. Показано, что возникающие напряжения во многих случаях превышают пределы текучести конструкционных сталей и неизбежно вызывают эрозионное разрушение поверхностных слоев лопасти.
Предложены зависимости для определения размеров зоны фрикционного газоабразивного изнашивания.
Результаты исследований могут быть использованы в инженерной практике при конструировании радиальных лопастей и в учебном процессе.

Los ecosistemas de manglar son de vital importancia por los servicios ecosistémicos que aportan a las comunidades ribereñas anexas del municipio de Acapulco, Guerrero. El objetivo principal de este estudio fue evaluar el daño estructural que sufrieron estos ecosistemas de manglares en la Laguna Negra de Puerto Marqués y de Tres Palos, por los impactos del huracán Otis. Se utilizó una metodología cualitativa que permitió recolectar evidencias que se obtuvieron a través de recorridos a pie y en cayucos; con el apoyo de una ficha de registro se recolectaron evidencias sobre la situación que guarda este ecosistema con material fotográfico como evidencia; además se realizaron entrevistas semiestructuradas a informantes clave que viven en las localidades anexas al área de estudio. A través de imágenes aéreas de Google Earth y de la NASA se realizó un comparativo de cobertura vegetal y se obtuvieron indicadores visuales de la afectación en la superficie vegetal de las áreas de manglar más representativas de ambos cuerpos lagunares. Se determinó la relevancia espacial del ecosistema de manglar en las lagunas por medio de cartografía en formato Shape a partir de cinco años de referencia con el software QGIS y con base en los resultados se diseñó una propuesta de restauración ecológica fundamentada en la ingeniería y la ecología forense. Los resultados obtenidos mostraron una enorme pérdida de cobertura de manglar en ambas lagunas; en la Laguna Negra la pérdida de este ecosistema prácticamente fue total. Se pudo documentar que los aportes de agua a este ecosistema fueron bloqueados por asolvamientos y arena, piedras, vegetación y árboles derivados, además de la enorme cantidad de residuos que están depositando dentro del área del manglar. Por otro lado, el manglar de la Laguna de Tres Palos, en la cercanía con Barra Vieja, se ha visto deteriorado en las últimas fechas debido a los rellenos del humedal y a los cambios de uso de suelo que acostumbran realizar las comunidades aledañas para cultivar coco o maíz. Se realizó una proyección hipotética aplicable en el proceso de restauración en ambos sistemas lagunares.
Artificial Intelligence. Concepts and Interpretation

Artificial intelligence (AI) has been developing dynamically, and becomes a core issue in the public debate. The related contemporary achievements, such as generative language models, change the way we work, especially in creative fields. The article analyses the historical development of AI, from the Dartmouth workshops in 1956, through John McCarthy’s and Alan Turing’s symbolic approach to artificial intelligence, to the effect of cybernetics on contemporary technologies. It draws attention to Richard Dreyfuss’ and John Searle’s critique of AI, emphasising their meaning in redefining the differences between human and artificial intelligence. In the context of the AI revolution, the article poses a question about the future of design and technology, considering if the process of human adaptation keeps up with the development of machines. It also refers to ethical aspects of automation, and the growing importance of creative thinking in the face of technological progress. Keywords: artificial intelligence (AI), cybernetics, philosophy, history, design
Ethical Design in the Generative AI Era
Authors: Rudnicka Patrycja
Published: November 2024

Implementation of AI solutions is unavoidable on the markets, where the combination of time deficits and the need for constant creation of new solutions is especially demanding, that is i.a. in creative industries. Like a lens, generative AI concentrates the majority of threats and possibilities, resulting from technological changes of the recent decade. Still, despite the constant media confusion, great number of viral content, guides, courses and codes, we have much work to do towards defining the rules and specifics of designers’ collaboration with AI, and the related ethical challenges. The AI development is ahead of legal regulations and stimulates changes, and the constant information overload does not encourage reflection on AI systems and their role in design. Becoming aware of the possibilities and limitations of generative AI, however, is the only way to its sustainable and ethical use. The first step will be to reflect on and understand the possibilities and changes AI carries in the area of creation, intellectual property, and narrowing the competency gap (the lack of competency in reference to a given human team). The second step will be the efficient identification of risks and indication of new areas of responsibility to designers, who would like to apply new technologies in their work. Keywords: design, ethics, artificial intelligence (AI), responsibility, designer’s role
On the Struggle of a Dialogue – Art of Communicating with AI in Design
Authors: Kruk Patrycja
Published: November 2024

The rapid spread of LLMs (large language models) and other technologies based on generated content and image has significantly impacted the perception of creative work, including the area of product design. Tools using generative AI enable the acceleration or facilitation of the ideation processes, producing many different solutions to a given problem. Beside facilitating creative processes due to automation of some tasks, especially those based on working with large databases, generative AI can assume a form of specific creativity stimulator. The key notion conditioning the effective use of generative AI tools is the ability of asking adequate questions. This requires increased engagement in works towards changes in education, currently directed to reproduction and memorisation. Contrary to popular opinion, popularisation of AI as element of design process could result in expanding the spectrum of designer’s possibilities. Methodical education in compliance with the basics of cause-and-effect thinking and teaching the analytical design approach guarantee providing the young generation with solid foundation of collaboration with generative AI models. Keywords: artificial intelligence (AI), design education, creativity
Laboratory of Changes. Design Education in the Face of Artificial Intelligence
Authors: Janota Katarzyna
Published: November 2024

The development of generative AI brings new challenges, which could result in total redefinition of design education and practice alike. The article shortly describes the evolution of design over the recent 15 years. It demonstrates how UX and related areas have risen in importance, which made many persons dealing with the more traditional forms of design acquire new skills, including business ones. Next, it refers this “evolution” to the current moment, when the development and increase in AI use forces designers to, once again, re-evaluate their competenggcy in this context. The text also proposes a thesis that the long-term designers’ engagement in building the foundation of technological status quo does not translate into reflection on the variants of automation conductive of life and well-being. It draws attention to the fact that shaping educational programmes in response to the market needs limits the possibilities of appropriate consideration of other prospective variants of technology or social and economic consequences of automation. In parallel, it indicates the potential of change in this situation, which should be commenced by asking adequate, bold questions and challenging the status quo. Keywords: design education, design critique, evolution of design practice, automation, artificial intelligence (AI)
