The constant technological advances and progresses in tokamak research constantly show up new control challenges. In this context, the control of the poloidal beta has arisen as a relevant issue. In this paper a real-time observer based on the real-time analysis of diamagnetic measurements that has been developed for the Tokamak a Configuration Variable (TCV) is presented. The algorithm proposed combine measurements of the diamagnetic loops, flux loops and magnetic probes. Afterwards, some simulations are carried out with the purpose of testing the observer. Finally, once the observer has been developed and validated through simulations, it is implemented on the TCV reactor and applied to the real-time control of poloidal beta of the plasma. The results of the experiments show the feasibility of the observer for real-time tokamak plasma control purposes.

To help health economic modelers respond to demands for greater use of complex systems models in public health. To propose identifiable features of such models and support researchers to plan public health modeling projects using these models. A working group of experts in complex systems modeling and economic evaluation was brought together to develop and jointly write guidance for the use of complex systems models for health economic analysis. The content of workshops was informed by a scoping review. A public health complex systems model for economic evaluation is defined as a quantitative, dynamic, non-linear model that incorporates feedback and interactions among model elements, in order to capture emergent outcomes and estimate health, economic and potentially other consequences to inform public policies. The guidance covers: when complex systems modeling is needed;principles for designing a complex systems model;and how to choose an appropriate modeling technique. This paper provides a definition to identify and characterize complex systems models for economic evaluations and proposes guidance on key aspects of the process for health economics analysis. This document will support the development of complex systems models, with impact on public health systems policy and decision making.
