Tailored Heat-Treatment Strategies for W360 Tool Steel Produced by Directed Energy Deposition

Laser-directed energy deposition (L-DED) was used to manufacture samples of the newly developed W360 hot-work tool steel from voestalpine Böhler Edelstahl. Various heat-treatment processes, including austenitising followed by air or water-quenching and tempering, as well as direc...

Crude protein prediction in grain-based powder systems using VIS–NIR hyperspectral imaging and feedforward neural networks

Abstract Crude protein content is a key quality parameter in cereal processing, yet conventional reference methods such as Dumas combustion are destructive and require sample preparation. Hyperspectral imaging (HSI) extends conventional point spectroscopy by coupling broadband sp...

Deterministic, rule-following trajectory generation system for waypoint flight

Abstract Advanced Air Mobility operations require flight guidance systems that exhibit predictable, deterministic behavior and remain compatible with established navigation standards. Many existing online trajectory generation methods rely on numerical optimization, or time-param...

Secure Set-based State Estimation for Safety-Critical Applications under Adversarial Attacks on Sensors

Set-based state estimation provides guaranteed state inclusion certificates that are crucial for the safety verification of dynamical systems. However, when system sensors are subject to cyberattacks, maintaining both safety and security guarantees becomes a fundamental challenge...

Cost Savings of Smart Unidirectional and Bidirectional EVs Under Imperfect Foresight of Electricity Prices

Smart unidirectional and bidirectional charging of electric vehicles (EVs) has raised great attention in recent years, enabling access to enormous flexibility potential for the energy system. One use case often discussed is the utilization of this flexibility for arbitrage tradin...

Plant species richness is key for restoring grassland butterfly assemblages

Abstract Palaearctic grasslands are heavily threatened by land‐use changes that lead to degradation and habitat loss. Thus, successful grassland restoration for vegetation and wildlife is urgently needed. Butterflies, as sensitive indicators, could provide a holistic view of rest...

Sensory data-driven classification of complex regional pain syndrome: a multicentre cohort study

BACKGROUND: The underlying pathophysiological mechanisms of complex regional pain syndrome (CRPS) have been under debate in recent years. Previous studies identified mechanistic CRPS subtypes, which were characterised as 'cold' and 'warm' or peripheral and central phenotypes. Our...

Feasibility of energy expenditure estimation during outdoor walking using multimodal in-ear sensors: a preliminary validation study against indirect calorimetry

Abstract A growing number of portable devices has become available for daily physical activity and energy expenditure (EE) monitoring. Although several studies have examined EE estimation using heart rate (HR) and accelerometry (ACC), no study to date has explored EE prediction b...
