The Lagrange multiplier method for combining observations and models (i.e., the adjoint method or 4D-VAR) has been avoided or approximated when the numerical model is highly nonlinear or chaotic.This approach has been adopted primarily due to difficulties in the initialization of low-dimensional chaotic models, where the search for optimal initial
In this work, an adaptive fuzzy backstepping fault-tolerant control (FTC) issue is tackled for uncertain fractional-order (FO) nonlinear systems with sensor and actuator faults.A fuzzy logic system is exploited to manage unknown Onion Soup Bowls nonlinearity.In addition, a novel FO nonlinear filter-based dynamic surface control (DSC) method is cons
Most of combustible dusts present both fire and explosion hazard.Explosion may occur at certain concentrations of dust mixed with air and in the presence of an ignition source.The threat posed by this real danger was confirmed by the events that took place in economic units such as: feed factories, wood products, textile industry, steel, etc.Among
The rocking motion of two-wheeled Decoupage Paper suitcases is investigated.A rigid body mechanical model of the suitcase is constructed.All of the possible motion states (both wheels on the ground, one wheel on the ground, none of the wheels on the ground) are taken into account.The switching between the motion states is accomplished by a simple i
To prevent Onion Soup Bowls the transmissions of mosquito-borne diseases (e.g., malaria, dengue fever), recent works have considered the problem of using the sterile insect technique to reduce or eradicate the wild mosquito population.It is important to consider how reproductive advantage of the wild mosquito population offsets the success of popul
