abstract = {{Shape formation is one of the most thoroughly studied problems in programmable matter and swarm robotics. However, in many models, the class of shapes that can be formed is highly restricted due to the particles’ limited memory. In the hybrid model, an active agent with the computational power of a deterministic finite automaton can form shapes by lifting and placing passive tiles on the triangular lattice. We study the shape reconfiguration problem where the agent additionally has the ability to distinguish so-called target nodes from non-target nodes and needs to form a target shape from the initial tile configuration. We present a worst-case optimal O(mn) algorithm for simply connected target shapes, where m is the initial number of unoccupied target nodes and n is the total number of tiles. Furthermore, we show how an agent can reconfigure a large class of target shapes with holes in O(n^4) steps.}},

Employees in highly demanding, interdependent work environments face a dilemma: while avoidance‐focused job crafting can preserve their own well‐being, these self‐initiated changes to their jobs could negatively affect coworkers. Drawing on qualitative interviews with 81 employees concurrently working for multiple agile teams in a European automotive corporation, we explore how employees navigate this dilemma. Our findings reveal three primary job crafting strategies—eliminating tasks, reducing task investment, and scheduling tasks in uninterrupted time blocks—that decrease employees' emotional exhaustion yet burden coworkers and slow team processes. We identify two distinct pathways for navigating this dilemma: in self‐oriented job crafting, employees announce their strategies unilaterally and implement them despite coworkers' objections, shifting the burden of interdependence onto coworkers and fueling coworker frustration; in prosocial job crafting, they openly suggest crafting strategies, discuss them with coworkers, and adjust plans to balance self‐preservation with coworkers' needs, thus partially internalizing the burden of interdependence. Our study advances research on socially embedded job crafting by revealing contrasting ways to manage interdependence. It also extends job crafting research by showing when and why avoidance crafting can effectively mitigate high job demands and by illustrating how avoidance and approach crafting can blend within a single strategy.}},

abstract = {{Die effiziente Nutzung von Ressourcen ist in der modernen Produktentwicklung von zentraler Bedeutung, nicht nur im Hinblick auf Materialien, sondern auch angesichts des Fachkräftemangels. Dabei sollten menschliche Arbeitskräfte gezielt eingesetzt und unnötige Iterationen zwischen Abteilungen vermieden werden, wobei die Kommunikation zwischen Konstruktion und Berechnung eine entscheidende Rolle spielt. Im Rahmen dieser Arbeit wird eine Methode entwickelt, die es Konstrukteuren ermöglicht, mithilfe künstlicher neuronaler Netze schnell mechanisch optimierte Bauteilgeometrien vorzuschlagen und so Korrekturschleifen zu minimieren. Hierfür wird eine Entwicklungsumgebung analysiert, die die Integration neuronaler Netze in bestehende Konstruktions- und Optimierungsprozesse erlaubt, einschließlich der Definition von Eingaben, Ausgaben, Datenformaten, Datensätzen und Schnittstellen zu kommerzieller Software. Zur Sicher-stellung der generalisierten Nutzbarkeit der Trainingsdaten werden Bauteilgeometrien zunächst mithilfe geometrischer Primitive abstrahiert und anschließend zu Gesamtgeometrien zusammengesetzt. Die Machbarkeitsstudie zeigt, dass mechanisch optimierte Bauteilgeometrien auf diese Weise erfolgreich vorhergesagt werden können. Obwohl noch gewisse Einschränkungen bestehen hinsichtlich der Schnittstellendefinition zwischen den Primitiven oder der Umrechnung von globalen auf lokale Randbedingungen, bietet die Methode eine solide Grundlage für weiterführende Forschungsarbeiten in diesem Bereich.}},

abstract = {{Censorship is employed by many governments and ISPs worldwide, with an increasing trend in recent years. One of the most censored protocols is DNS: censors target unencrypted and encrypted DNS to prevent clients from resolving the domain name of unwanted websites. Despite much research on DNS censorship, only a few tools can circumvent it.To support users affected by DNS censorship, we present DPYProxy-DNS, a DNS resolver that automatically detects and employs a working DNS censorship circumvention. We demonstrate the effectiveness of DPYProxy-DNS by automatically circumventing DNS censorship in China and Iran and analyzing DNS censorship mechanisms in these countries. Our analyses re veal that DNS censorship in Iran is ineffective against encrypted DNS. In China, DPYProxy-DNS revealed two consistently working circumvention techniques for unencrypted DNS: TCP segmentation for DNS over TCP and ignoring DNS responses injected by the Great Firewall of China (GFW). Our findings reveal varying levels of DNS censorship across different countries, underscoring the importance of the automated circumvention approach we provide with DPYProxy-DNS.}},

Separation processes, such as distillation and stripping, are highly energy‐intensive. Typically, energy is supplied indirectly via a reboiler, which is often associated with heat losses. We present a preliminary theoretical evaluation of a novel concept to supply energy directly inside the column using heatable structured packings. These packings can be produced by multi‐material 3D printing, resulting in a conductive inner layer and an insulating outer layer. Functioning as electric resistance heaters, these packings serve as heating elements. In this numerical study, we compared different scenarios of energy supply along the height of the column, including uniform distribution, applying a temperature profile, and using or omitting a reboiler.}},

Clinching is a widely adopted joining technique in the automotive industry, enabling the fabrication of lightweight structures from dissimilar sheet materials. Accurate prediction of the fatigue life of clinched joints is essential for ensuring structural safety and minimizing development costs. However, full 3D fatigue simulations over millions of cycles are computationally intensive due to the complexity of contact mechanics. This study introduces a 2D numerical model that circumvents direct contact modeling by applying a slip condition at the sheet interface, significantly reducing computational demands. A micro‐slip friction model is used to represent the mechanical interface behavior, while a two‐scale damage model captures the fatigue damage evolution. The model is validated against experimental data and used to investigate the influence of friction coefficient and tangential contact stiffness on fatigue life, highlighting its efficiency and predictive capability.}},

Salt-spray testing is widely used in the automotive and materials industries to assess the corrosion resistance of protective coatings, where uniform corrosion is a key indicator of material performance. This work presents a numerical uniform corrosion model that predicts the corrosion rate of hot-dip zinc in salt-spray environments by incorporating electrochemical reactions, mass transport via the Nernst–Planck equation, and ionic-strength effects through the Brønsted–Bjerrum relation. The model is calibrated using immersion-test data and extended to account for electrolyte layer growth, droplet deposition, and periodic run-off in salt-spray environments. The calibration establishes a relationship between the porosity of the zinc oxide layer and the rate constant of zinc oxide precipitation. The validated model reproduces the transition from activation- to diffusion-controlled corrosion and captures the experimentally observed corrosion kinetics with an error margin of 20% when electrolyte renewal is included. The results highlight the decisive role of electrolyte dynamics in salt-spray environments and provide a foundation for extending the framework to more complex cyclic corrosion tests.}},
