The main results of this manuscript consist in converting the infinite-dimensional continuous-time systems into infinite-dimensional discrete-time systems for which the operators dynamics are matrices, in solving the LQ-optimal control problem in discrete-time and then in interpreting the solution in the continuous-time variables, giving rise to the optimal boundary control input. The results are applied to two examples, a small network of three vibrating strings and a co-current heat-exchanger, for which boundary sensors and actuators are considered. 2 2024 10.48550/arXiv.2402.13706 https://arxiv.org/abs/2402.13706 Anthony Hastir Birgit Jacob Hans Zwart inbook Port-Hamiltonian Systems Modelling in Electrical Engineering 2024 10.1007/978-3-031-54517-7_15 Scientific Computing in Electrical Engineering.

Reis article Spectral analysis of a class of linear hyperbolic partial differential equations A class of linear hyperbolic partial differential equations, sometimes called networks of waves, is considered. For this class of systems, necessary and sufficient conditions are formulated for the operator dynamics to generate a C_0-group. This property turns out to be equivalent to the Riesz-spectral nature of that operator. In that case, its spectrum is computed explicitly, leading to easily checkable stability conditions. We apply our results to characterize exponential stability of a co- current heat exchanger. 2024 10.1109/LCSYS.2024.3403472 IEEE Control Systems Letters 8 766-771 https://arxiv.org/abs/2403.00498 Anthony Hastir Birgit Jacob Hans Zwart article Stability via closure relations with applications to dissipative and port-Hamiltonian systems 2024 10.1007/s00028-024-00992-5 J.

201-208 Tanja Eisner Bálint Farkas article kirschNeodymiumIIIMediated2007 Neodymium(III)-Mediated Reformatsky-Type Reactions of α-Halo Ketones with Carbonyl Compounds In a neodymium(III) iodide induced process, alpha-bromo ketones 1 and aldehydes 2 are effectively converted into aldol products 3. This Reformatsky-type reaction proceeds through the formation of a neodymium enolate at room temperature in CH2Cl2. The analogous reaction in the presence of NdBr3/NaI at 50 °C in THF favors the formation of corresponding aldol\textendash Tishchenko products 5 in good yields. Studies to define the scope and limitations of these reactions mediated by neodymium(III) salts are also described. 2007 8 1099-0690 10.1002/ejoc.200700240 European Journal of Organic Chemistry 2007 3711–3717 22 Aldol reactions,Enolates,Lanthanides,Neodymium Stefan F.
