We combine the adaptive and multilevel approaches to the BDDC and formulate a method which allows an adaptive selection of constraints on each decomposition level. We also present a strategy for the solution of local eigenvalue problems in the adaptive algorithm using the LOBPCG method with a preconditioner based on standard components of the BDDC. The effectiveness of the method is illustrated...

this paper presents a new centralized adaptive method under frequency load shedding. sometimes, after initial frequency drop following severe disturbances, although the system frequency returns to its permissible value, however, the system might become unstable due to voltage problems. in this regard, the paper proposes a new centralized adaptive load shedding method to enhance the voltage stab...

OBJECTIVE Brain-computer interfaces (BCIs) based on sensorimotor rhythms use a variety of motor tasks, such as imagining moving the right or left hand, the feet or the tongue. Finding the tasks that yield best performance, specifically to each user, is a time-consuming preliminary phase to a BCI experiment. This study presents a new adaptive procedure to automatically select (online) the most p...

In this paper, a novel robust adaptive sliding-mode control scheme is presented high precision position control for a permanent magnet synchronous linear motor (PMSLM) servo system under the influence of unknown parameters, nonlinear friction, cogging forces, and external distance. The proposed strategy effectively combines the design techniques of adaptive control and sliding-mode control. In ...

Approximate Bayesian Computation (ABC) methods are increasingly used for inference in situations which the likelihood function is either computationally costly or intractable to evaluate. Extensions of basic ABC rejection algorithm have improved computational efficiency procedure and broadened its applicability. The – Population Monte Carlo (ABC-PMC) approach has become a popular choice approxi...

We propose, analyze and test a new adaptive penalty scheme that picks the parameter $$\epsilon $$ element by small where $$\nabla \cdot u^h$$ is large. start analyzing testing on most simple but interesting setting, Stokes problem. Finally, we extend algorithm incompressible Navier equation complex flow problems. Tests indicate adaptive- method predicts behavior accurately. The developed in als...
