This contribution presents an innovative and integrated framework for real-time-process reconciliation and optimization (RTRO) in large continuous open pit coal mines. RTRO-Coal is currently developed, validated, tested and implemented as part of a multi-national multi-partner European Union funded R&D project. The key concept is to promote a shift in paradigm from intermittent discontinuous to a continuous process monitoring and quality management system in large scale coal mining operations. The framework is based on a real-time feedback control loop linking online data acquired during extraction rapidly with a sequentially up-datable resource model. The up-to-date model is integrated with a real-time optimization of short-term sequencing and production control decisions. Improved decisions are expected to lead to increased resource-and process efficiency and support a sustainable extraction of natural resources. This contribution introduces to the framework, discusses main building blocks and illustrates the value added by the means of selected examples. ; Geoscience & Engineering ; Civil Engineering and Geosciences

Most practitioners of critical librarianship agree that subject description is both valuable and political. Subject headings can either reinforce or subvert hierarchies of social domination. Outside the library profession, however, even among stakeholders such as authors, there is little awareness that librarians think or care about the politics of subject description. Talking about subject description with the authors whose works we hold and represent can strengthen our relationships, demystify our work, and hold us accountable for our practices. This paper discusses an interview I conducted with author Eli Clare about the Library of Congress Subject Headings assigned to his book, Exile and Pride: Disability, Queerness, and Liberation. Clare describes feeling dismayed by and detached from the subject headings assigned to his book. He offers a sophisticated analysis of individual headings. He also reflects on the subject description project itself, using theories from genderqueer and transgender activism to discuss the limitations of categorization.
