New conditions on the existence of eight limit cycles for a class of cubic differential systems were derived by solving a system of large polynomial equations and inequalities.
Analytical expressions for the apparent longitudinal relaxation time of such systems were derived from a combination of the dipolar field theory and product operator formalism.
The results show that three scenarios of collapsed energy systems were described, in which policy options to be taken toward achieving resilient energy systems were derived.
73 indicators for Cultural Identity, Landscape Aesthetics, and Knowledge Systems were derived, revealing that socio-cultural structures and the socioeconomic situation of farmers influence their view on landscape-related cultural services.
Governing equations for evolution of concentration and temperature in three-component systems were derived in the framework of classical irreversible thermodynamics using Onsager's variational principle and were presented for solvent/solvent/polymer and solvent/polymer/polymer systems.
Relatively moving systems were derived and tested (Fiala et al., 2011 [1]), and the influence of the motion on a superposed electromagnetic field was proved to exist already at relative motion speeds.
