Risk-Aware and Stable Edge Server Selection Under Network Latency SLOs

Apr 23, 2026

This work addresses the challenge of dynamic server selection in edge computing under stringent latency SLOs, where decisions must jointly manage tail-risk violations and switching stability. The authors propose a lightweight, interpretable decision framework that uniquely co-optimizes tail-risk control and switching stability: it estimates SLO violation risk using normal approximation and the Cantelli inequality, while incorporating a hysteresis mechanism to suppress excessive switching. Experimental results under a 0.5-second SLO demonstrate that, compared to a baseline relying solely on mean latency, the proposed method reduces deadline miss rate from 39% to 34%, cuts switching frequency by 88% (down to 5.5%), and maintains average latency stably at 0.45 seconds, thereby significantly enhancing both system robustness and efficiency.

Towards an Inclusive Digital Society: Digital Accessibility Framework for Visually Impaired Citizens in Swiss Public Administration

Mar 12, 2025

This study addresses the implementation gap in Swiss public-sector compliance with digital accessibility regulations—particularly the Web Content Accessibility Guidelines (WCAG)—identifying three core barriers: resource constraints, policy fragmentation, and insufficient technical capacity. Adopting a design science research paradigm, we propose the first integrative framework that systematically aligns WCAG standards with Switzerland’s nationally adopted HERMES project management methodology, covering the entire lifecycle of governmental digital services. The framework transforms accessibility from a static compliance requirement into a dynamic, usability-driven practice, substantially bridging the gap between regulatory text and the lived experience of visually impaired citizens. Empirically validated within Swiss federal and cantonal contexts, it delivers a reusable methodological foundation and actionable implementation pathway for inclusive digital governance under Society 5.0. Notably, this work represents the first structured integration of an international accessibility standard with a national project management framework in the public administration domain.
