This research examines the integration of information and communication technologies in education (ICTE) among teachers, as part of an exploration to evaluate a global model for the successful implementation of ICTE in education. The results revealed widespread adoption of ICTE by teachers, with the majority having used these technologies over a long period of time (60%), testifying to their growing recognition in pedagogical practices. Teachers also noted a positive impact of ICTE on learners’ skills (76%), although there were discrepancies as to their effect on student engagement and motivation). At the same time, challenges remain, including the limited availability of equipment in schools (58%), and the ongoing need for teacher training and support. Overall, this research highlights the growing importance of ICTE in education, while underlining the challenges and professional development needs for more effective integration of these technologies into educational practic. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Effective emergency response planning is vital for regional climate resilience, requiring coordination across multiple government sectors. Collective management of emergency resources enhances allocation efficiency at a regional scale, overcoming local constraints. However, prioritisation becomes challenging when resources are shared collectively. Evolving emergency events further complicate forecasting future demands, as shortages trigger the need for external support whilst increasing estimation uncertainty. To address these challenges, we implemented an emergency response Digital Twin, integrating a Resource Allocation Model with short-term weather-related predictions and real-time updates. This paper focuses on the model’s application within a hybrid simulation framework, tested in a flooding case study in Torbay, UK. The approach enables a holistic assessment of emergency response by leveraging collective resource advantages whilst considering cascading infrastructure failures. By improving resource distribution and resilience strategies, the model supports more effective decision-making for regional emergency preparedness. © 2025 SW 2025 - OR Society 12th simulation Workshop, Proceedings.

The industrial sector accounts for a significant share of global energy consumption and CO 2 emissions, with steam systems playing a critical role in process heating and power generation. This paper presents a comparative analysis of three case studies conducted in Morocco's pulp and paper, agri-food, and plastic industries, all of which are considered energy-intensive sectors. The objective is to assess the performance of these industries' steam systems using the Steam System Scoping Tool (SSST) and evaluate their system efficiencies. The study highlights energy-saving actions implemented in each case and demonstrates how simple maintenance measures, such as repairing steam leaks, controlling excess air, and improving insulation, can significantly enhance energy efficiency and reduce costs. By adopting a systems approach to steam optimization, the study proves that cost-effective actions with short payback periods can lead to substantial energy savings without requiring major capital investments. The annual cumulative financial savings across the three case studies amounted to $608,547, with energy savings of 40,987.65 GJ and an emissions reduction of 2,809.65 tons of CO 2 . Despite focusing on different industries, the findings are applicable to a broad range of sectors, as the core components of steam systems are widely shared. Additionally, this work supports the African Union's Agenda 2063 and the United Nations Sustainable Development Goals (SDGs) by providing practical insights and recommendations for improving industrial energy efficiency and reducing environmental impact.

The demand for natural fiber-reinforced composites in engineering design has increased, offering advantages like low density and environmental benefits. However, their long-term behavior, particularly under cyclic loading, remains limited. This study aims to predict the fatigue behavior of composites reinforced with natural fiber using several predictive models of regression trained on a database of studies. This model reduces experimental testing and improves prediction quality by avoiding computationally intensive data points.

Revisiting convolutive blind source separation for identifying spiking motor neuron activity: From theory to practice

arXiv 2025年

作者： Klotz, Thomas Rohlén, Robin Institute for Modelling and Simulation of Biomechanical Systems University of Stuttgart Pfaffenwaldring 5a Stuttgart70569 Germany Department of Diagnostics and Intervention Umeå University Umeå901 87 Sweden

Objective: Identifying the spiking activity of alpha motor neurons (MNs) non-invasively is possible by decomposing signals from active muscles, e.g., obtained with surface electromyography (EMG) or ultrasound. The theoretical background of MN identification using these techniques is convolutive blind source separation (cBSS), in which different algorithms have been developed and validated. However, the existence and identifiability of inverse solutions and the corresponding estimation errors are not fully understood. In addition, the guidelines for selecting appropriate parameters are often built on empirical observations, limiting the translation to clinical applications and other modalities. Approach: We revisited the cBSS model for EMG-based MN identification, augmented it with new theoretical insights and derived a framework that can predict the existence of solutions for spike train estimates. This framework allows the quantification of source estimation errors due to the imperfect inversion of the motor unit action potentials (MUAP), physiological and non-physiological noise, and the ill-conditioning of the inverse problem. To bridge the gap between theory and practice, we used computer simulations. Main results: (1) Increasing the similarity of MUAPs or the correlation between spike trains increases the bias for detecting MN spike trains linked with high amplitude MUAPs. (2) The optimal objective function depends on the expected spike amplitude, spike amplitude statistics and the amplitude of background spikes. (3) There is some wiggle room for MN detection given non-stationary MUAPs. (4) There is no connection between MUAP duration and extension factor, in contrast to previous guidelines. (5) Source quality metrics like the silhouette score (SIL) or the pulse-to-noise ratio (PNR) are highly correlated with a source’s objective function output. (6) Considering established source quality measures, SIL is superior to PNR. Significance: We expect these findings

This paper describes the delivery of a spacecraft to Saturn's moon Titan. Once captured at Titan and deployed, a Zeppelin type spacecraft would ride the moon's stratified and dynamic wind currents, operating for several years. The inflatable spacecraft and science package would flyover and survey large segments of the surface of Titan including its poles, mountains, valleys and liquid lakes. The NASA Space Launch System (SLS) is capable of injecting a 24.1-mt payload to an injection energy (C3) of 29 km2/s2, required for launch in 2035. Flight time to Saturn will be 7.8-years. Carried with the spacecraft will be trailing tethers, deployable probes, and drones that descend through the clouds and the various layers of the atmosphere to the surface. The SLS Block 1 vehicle successfully flew its first mission in late 2022. The SLS is being upgraded to the new Block 2 configuration with the addition of a new large Exploration Upper Stage (EUS). The EUS will substantially increase SLS payload capability, making robust, high science outer planet missions like this mission to Titan a reality © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA.

This research evaluates the effectiveness of two types of phase-change materials (PCMs): one paraffin-based (PCM1) and the other bio-based (PCM2), integrated within a multi-layer wall system. The thermal management and energy-saving capabilities of these MCPs were examined under diverse climatic conditions by numerical simulations performed with ANSYS 2021 R1. The results indicate that PCM1 is more efficient at storing latent heat, allowing it to maintain thermal conditions for extended durations, which makes it particularly suitable for regions experiencing constant temperature fluctuations. On the other hand, PCM2 reacts quickly to sudden temperature shifts because of its reduced melting point and enhanced thermal conductivity, optimizing performance across various environmental settings. Both PCMs markedly diminished indoor temperature fluctuations, achieving energy savings of roughly 18% for cooling requirements. Furthermore, PCM2's bio-based composition provides significant environmental benefits, consistent with sustainable construction methodologies. The results highlight the synergistic advantages of PCM1 and PCM2, stressing the necessity to customize PCM selection according to particular climatic and operational demands to improve building energy efficiency and thermal comfort. This research advocates for the incorporation of phase change materials into wall systems as an effective strategy for sustainable architectural solutions.

modelling Material Injection Into Porous Structures With the Theory of Porous Media Under Non-isothermal Conditions

arXiv 2025年

作者： Völter, Jan-Sören L. Trivedi, Zubin Ricken, Tim Röhrle, Oliver Institute for Modelling and Simulation of Biomechanical Systems University of Stuttgart Pfaffenwaldring 5a Stuttgart70569 Germany Institute of Structural Mechanics and Dynamics of Aerospace Structures University of Stuttgart Pfaffenwaldring 27 Stuttgart70569 Germany University of Stuttgart Pfaffenwaldring 5a Stuttgart70569 Germany

In this work, the Theory of Porous Media (TPM) is employed to model percutaneous vertebroplasty, a medical procedure in which acrylic cement is injected into cancellous vertebral bone. Previously, isothermal macroscale models have been derived to describe this material injection and the mechanical interactions which arise. However, the temperature of the injected cement is typically below the human body temperature, necessitating the extension of these models to the non-isothermal case. Following the modelling principles of the TPM and considering local thermal non-equilibrium conditions, our model introduces three energy balances as well as additional constitutive relations. If restricted to local thermal equilibrium conditions, our model equations are in agreement with other examples of TPM-based models. We observe that our model elicits physically reasonable behaviour in numerical simulations which employ parameter values and initial and boundary conditions relevant for our application. Noting that we neglect capillary effects, we claim our model to be thermodynamically consistent despite the employment of simplifying assumptions during its derivation, such as the Coleman and Noll procedure. © 2025, CC BY.

Effective collaboration in simulation modelling is possibly one of the key factors in the success of a simulation project. Computer Supported Cooperative Work is a research field that has investigated this in other domains. This field has led to the technological development of software, or groupware, to facilitate group working. This paper investigates the appropriateness of groupware in simulation modelling by introducing Microsoft’s NetMeeting, an exemplar of this technology. This groupware is discussed in terms of simulation modelling activities. A short survey of expert opinion is also presented to evaluate the usefulness of this technology. The survey shows that application sharing is clearly perceived to be the most useful feature of NetMeeting. © 2000, UK simulation Society. All right reserved.
