      This paper presents a systematic method for designing linear residual generators for fault detection and estimation in nonlinear systems. The approach is significant because it provides a structured way to address a critical problem in control systems: identifying and quantifying faults. The use of linear functional observers and disturbance-decoupling properties offers a potentially robust and efficient solution. The chemical reactor case study suggests practical applicability.

      Analysis

      This paper investigates the challenges of identifying divisive proposals in public policy discussions based on ranked preferences. It's relevant for designing online platforms for digital democracy, aiming to highlight issues needing further debate. The paper uses an axiomatic approach to demonstrate fundamental difficulties in defining and selecting divisive proposals that meet certain normative requirements.

      The paper shows that selecting the most divisive proposals in a manner that satisfies certain seemingly mild normative requirements faces a number of fundamental difficulties.

      Analysis

      This paper introduces a geometric approach to identify and model extremal dependence in bivariate data. It leverages the shape of a limit set (characterized by a gauge function) to determine asymptotic dependence or independence. The use of additively mixed gauge functions provides a flexible modeling framework that doesn't require prior knowledge of the dependence structure, offering a computationally efficient alternative to copula models. The paper's significance lies in its novel geometric perspective and its ability to handle both asymptotic dependence and independence scenarios.
