Business Strategy and the Environment, EarlyView.ABSTRACT The governance of chemicals and nanomaterials presents a critical challenge, as significant uncertainties regarding safety and sustainability match their innovation potential. This creates a “knowledge‐to‐action” gap, hindering the practical implementation of safety and sustainability by design (SSbD) principles.

Preconditioned AOR iterative methods for M-matrices
, 2009 Linear systems with M-matrices often appear in a wide variety of areas. In this paper, we give general preconditioners for solving the systems with nonsingular M-matrix.

Lecture 10: Preconditioned Iterative Methods for Linear Systems
, 2021 Iterative methods for the solution of linear systems of equations – such as stationary, semi-iterative, and Krylov subspace methods – are classical methods taught in numerical analysis courses, but adapting these methods to run efficiently at large-scale

Business Strategy and the Environment, EarlyView.ABSTRACT While industry platforms are widely recognized as enablers of circular innovation, we still know little about how they evolve to scale and sustain innovation as economic conditions tighten and circular economy funding schemes become more selective.

Connecting Thoughts and Actions: A Managerial Process Model on Circular Business Model Innovation
Business Strategy and the Environment, EarlyView.ABSTRACT Addressing environmental grand challenges such as resource scarcity requires circular business model innovation (CBMI) that enables firms to efficiently close and slow resource cycles through novel activity systems. Drawing on a grounded theory approach based on 59 in‐depth interviews with top managers from Swiss SMEs, we developed a process ...

All-at-once preconditioning in PDE-constrained optimization
, 2006 The optimization of functions subject to partial differential equations (PDE) plays an important role in many areas of science and industry. In this paper we introduce the basic concepts of PDE-constrained optimization and show how the all-at-once ...
