Thermal dehydration of CeP<Subscript>3</Subscript>O<Subscript>9</Subscript>·3H<Subscript>2</Subscript>O by controlled rate thermal analysis

The aim of this work is to highlight the importance of controlling the residual water vapour pressure above the sample as well as the rate of the thermal decomposition during the thermal dehydration of cerium cyclotriphosphate trihydrate CeP₃O₉·3H₂O. For this reason, the dehydration of the titled compound was followed by both techniques: the constant rate thermal analysis at P _H2O = 5 hPa and the conventional TG-DTA in air.     

Feedback stabilization of non-homogeneous bilinear systems with a finite time delay

This paper investigates the feedback stabilization of non-homogeneous delayed bilinear systems in Hilbert state space. More precisely, under an observability-like assumption, we prove the exponential and strong stability of the solution by using bounded feedback control. Partial stabilization is discussed as well. The proofs of the main results are based on the decomposition method. The decay estimates of the stabilized solutions are obtained. Finally, some examples are presented.
