Numerical modelling of a deep closed-loop geothermal system: evaluating the Eavor-Loop

Efficiency of closed loop geothermal heat pumps: A sensitivity analysis

Geothermal heat pumps are becoming more and more popular as the price of fossil fuels is increasing and a strong reduction of anthropogenic CO2 emissions is needed. The energy performances of these plants are closely related to the thermal and hydrogeological properties of the soil, but a proper design and installation also plays a crucial role. A set of flow and heat transport simulations has ...

Modelling and Experimental Study of Wax Deposition in Transportation Line Using a Flow Loop System

Prototype Closed-Loop Deep Brain Stimulation

Implantable neurostimulators have rapidly become established methods of treating a variety of neurological disorders. The development of implantable neural interfaces enable the testing of Norbert Wiener’s hypotheses regarding neural disorders and their relationship to ideas of cybernetics. However, currently deployed medical devices of this kind are open-loop. For example, DBS for treatment of...

A theory of desynchronisable closed loop system

The task of implementing a supervisory controller is non-trivial, even though different theories exist that allow automatic synthesis of these controllers in the form of automata. One of the reasons for this discord is due to the asynchronous interaction between a plant and its controller in implementations, whereas the existing supervisory control theories assume synchronous interaction. As a ...

Modelling Oligopolistic Closed Loop Supply Chains

This paper uses variational inequalities to model an oligopolistic closed-loop supply chain engaged in a Cournot pricing game. The manufacturers produce a homogenous product for a set of customer markets. The product can be comprised of both virgin materials and recycled materials obtained from used products returned by the customers. Society is modelled as an additional player whose objective ...
