Relaxation and Dynamic Processes
2 Although multiple pulse and multi-dimensional NMR techniques permit generation of off-diagonal density matrix elements and observation of complex coherence transfer processes, eventually the density operator returns to an equilibrium state in which all coherences (off-diagonal elements of the density operator) have decayed to zero and the populations of the energy levels of the system (diagon...
متن کاملStudying Dynamic behavior of Distributed Parameter Processes Behavior Based on Dominant Gain Concept and it’s Use in Controlling these Processes
In this paper, distributed parameter process systems behavior is studied in frequency domain. Based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. By using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...
متن کاملDynamic Processes in Capillary Fringes
Capillary fringes are highly dynamic and periodically changing zones at the interface between the water-saturated aquifer and the unsaturated zone. As a consequence, we observe steep gradients in terms of hydraulic state variables, biogeochemical conditions, and thus, biological activity (Berkowitz et al., 2004). With fluctuations of the groundwater table, this reactive zone moves dynamically a...
متن کاملModeling Dynamic Processes in TLA
The formal development method of VSE (Veriication Support Environment) for state-based systems is based on a variant of TLA. VSE supports structured speciications, modular reenements, and also modular proofs. There are applications where one wants (or has) to consider an indeenite number of processes or even processes that are created and deleted dynamically. The general problem that arises in ...
متن کاملWorkflows in Dynamic Development Processes
Process management systems are used in many domains to monitor and control processes. Development processes require specific support, which is not provided by conventional workflow systems. On the one hand, they comprise highly dynamic process parts, which cannot be defined until project runtime. On the other hand, development processes may contain subprocesses, which can be executed in the for...
