Single-board computers, such as Raspberry Pi, have enabled a wide variety of monitoring applications. Microcontroller development boards offer a similar functionality but at a lower cost. Still, they are not widely used, because they are supposed to be slow. This paper aims to evaluate the abilities of modern microcontrollers and compares them with those of single-board computers. For this purpose, experiments concerning power consumption and performance evaluation are conducted. The results suggest that promising low-cost microcontrollers exist, which could be applied to reduce cost and energy consumption per node or increase the number of nodes used simultaneously in one monitoring system. © 2023 ICE Publishing.

This research study examines the applications of the industrial metaverse in supply chain management. Thus, it reviews and analyzes the up-to-date knowledge along the Supply Chain Operations Reference Model. Therefore, a structured literature review is conducted. We derive six core functionalities of the industrial metaverse in supply chains: visibility and monitoring, prediction, simulation, collaboration, training, and optimization. Furthermore, their presence along the different phases of a supply chain is investigated. Besides the functionalities, the relationship between the industrial metaverse and simulation applications and digital twins is analyzed, and a brief description of possible metaverse architectures is provided. This study additionally derives research gaps within the emerging field of metaverse applications and research and defines paths to tackle them. © 2024 IEEE.

Analog and mixed-signal (A/MS) IC design is still a largely manual process. It lags far behind its digital counterpart were synthesis methods automate many key design steps. This advantage in digital roots from the possibility of a high degree of abstraction with manageable information loss from which a highly systematic digital flow arose. Not only does it incorporate automation throughout, but it also links the individual flow steps by well-defined interfaces. In analog, to the contrary, both a comparable flow approach and automation is largely missing. Even though key design steps, such as schematic and layout, are meanwhile linked well, other important steps, like breaking down a specification to a suitable topology, are not yet in place. Therefore, design teams develop individual design approaches in order to handle the complexity of analog design all the way from specification to layout. A major challenge is the lack of reproducibility, which roots from the lack of expert knowledge stored in the design data. Thus, in this tutorial paper, we address the shortcomings of the A/MS design flow and discuss how knowledge-based automaton methods can both systematize and automate key design steps. Also, we discuss how the steps can be linked together in order to form a systematic design flow. Our proposed A/MS IC design design flow considers automation from specification over schematic level to the layout level. © 2024 IEEE.

The emerging trend of Prescriptive Analytics tries to prescribe actionable decisions. The goal is to help production experts in automating their decisions in the factory. Decision making processes in factories mostly rely on experts inside the company. Current trends such as demographic shifts and shortages of skilled personnel are challenging organizations to find ways to become less dependent on the ad hoc availability of expert knowledge through digitalization and data analytics. Existing data analytics approaches for smart factories usually focus on description, diagnosis, and prediction. An approach to differentiate between different application areas of Prescriptive Analytics in a smart factory is presented. Focus areas for a useful application and integration of Prescriptive Analytics are derived. Based on these applications, design principles are constructed. They help decision makers to select future lighthouse use cases for development and help smart factory advocates to strategically decide which prescriptive analytics approaches to highlight. The resulting design principles are based on a literature review and validated in a workshop with experts from research. Approaches are differentiated and key characteristics for future Use Case design decisions are derived. © 2024 Elsevier B.V.. All rights reserved.

Solid-state batteries (SSBs) are a promising emerging battery technology for electromobility application. Along with new technical opportunities (higher energy density, lower safety risks), they introduce new cell chemistry configurations and novel materials in use. This leads to increased complexity of material composition and may reduce the recyclability of SSBs. To ensure circularity of SSB materials, it is important to consider their recyclability at the early stage of SSB development. This paper proposes an approach for identification of target materials for recycling within three types of SSBs with polymer, oxide and sulfide electrolytes. To consider environmental and economic perspectives, interdependencies of material dilution, their cost and environmental material footprint are analyzed using Sherwood and global warming potential (GWP)-plots. Furthermore, a socio-geopolitical aspect of supply risk is considered as a relevant criterion for targeting materials. Li is identified as the main target material for all considered SSBs and Co as a further one for oxide- and sulfide-based cells. Furthermore, an upscaling scenario to a battery pack considered changes in concentration of target materials and revealed direct recycling of composite cathode LLZO and LCO to be very beneficial. Results of this approach can be used by SSB developers and recyclers in order to strive for holistic design enabling recycling of identified target materials. © 2023 The Authors.

Effective balancing group management is vital for ensuring a stable electricity supply. However, significant deviations often occur without clear explanations, challenging grid reliability. This study introduces a comprehensive methodology that integrates correlation analysis, feature-based analysis, and linear regression to examine forecast discrepancies across day-ahead, intraday, and day-after timeframes. Utilizing daily and monthly Key Performance Indicators (KPIs), we analyzed over two million schedule notifications from 928 balance responsible parties within the 50Hertz Transmission System Operator (TSO) region. Our rigorously validated approach provides a sophisticated top-down evaluation of management behaviors, identifying underlying patterns and anomalies with enhanced accuracy. Aligning with the latest advancements in data analytics, this methodology aims to improve energy balance management by effectively detecting anomalies in daily forecast schedules for both production and consumption. © 2024 IEEE.

Testing complex systems is crucial for ensuring safety, especially in automated driving, where diverse data sources and variable environments pose challenges. Here, robust safety validation is critical but exhaustive n-way combinatorial testing is impractical due to the vast number of test cases. The STARS framework uses tree-based scenario classifiers to limit feature combinations in a given domain.

Nursing care jobs are predominantly described as burdensome. In particular, the workload and the time available to deal with it are in a state of imbalance. Nurses are very often under time pressure and have to make decisions under psychological, emotional and physical stresses. Machine learning methods and in particular, Decision Support systems (DSS) can be used to support nurses with improved information (e.g. visualization of individual health risks) for decisions that are not easy to make. As falls are one of the most common health problems in care facilities, we will present a concept of a DSS for the prevention of falls that was developed in the PFLIP research project. We explain our user-centered design process based on ISO 9241-210-2019. User feedback is obtained at each phase so that nurses can identify problems at an early stage. The result is a conceptual design, visualized as a click dummy, to identify individual fall risks and predict preventive measures to reduce the risk of falling. © 2024 The Author(s), published by De Gruyter.

Tunnel inspections require the detection of deformations in the tunnel geometry, cracks, delamination, and water inflow. Solutions for an automated detection of deformations, cracks and water inflow already exist and typically comprise mobile laser-scanners and cameras combined with deep learning methods. Delaminations on the other hand are often not visible on the surface and can’t be detected using these methods. The detection of delamination in tunnel linings is therefore up to date performed by manual hammering and acoustic detection. The results are time consuming and labor-intensive inspections, subjective measurements, poor comparisons over epochs and a low degree of digitization. We present a concept of a novel system that aims to replace the manual hammering for acoustic delamination detection using a remote sensing approach. A strong, pulsed laser serves as a hammer and creates a plasma induced shockwave on the concrete surface. If a delamination is present this shockwave excites characteristic, resonant vibrations. A second, narrow-linewidth laser is employed in a customized laser doppler vibrometer setup to remotely detect these vibrations via a coherent measurement technique. In combination with laser scanners and cameras, the laser based remote sensing technique has the potential to help automating the process of tunnel inspections by delivering objective data that can be used in deep learning-based evaluation methods and for building information modeling (BIM) compliant assessment. A first mobile prototype for measurements outside the lab has been developed and is being presented in detail. © 2023 SPIE.

The digital twin in manufacturing, also called digital factory twin (DFT), is not only a recent technology but also a polymorphic concept which generates a profusion of state-of-the-art work from industry and research without real coherence. The work relates to very different realities including various definitions, shapes, models and applications. A wide variety of architectures are proposed and there is a significant lack of information on how to deploy a digital twin efficiently and how to define an appropriate architecture. The DFT is often implemented use-case-driven and in various ways concerning IT architectures. The paper proposes a reference architecture based on enterprise architecture modelling language ArchiMate and TOGAF principles, which allows to model business architectures and IT architectures. We make use of that and model a DFT business architecture based on the lifecycle of a factory and a DFT IT architecture based on IT applications and IT functions.
