In order to improve the trajectory tracking accuracy of an Underwater Vehicle Manipulator System (UVMS) under uncertain disturbance conditions ocean current, a Model-free Adaptive Control (MFAC) method was used. Combined with Radial Basis Function Neural Networks (RBFNN), RBFNN-MFAC is proposed performance controller. A hydrodynamic model UVMS defined in commercial software, Fluent, calculate h...

In this paper, we propose new variants of the two-step Adams-Bashforth and the one-step Adams-Moulton methods for the numerical integration of ordinary differential equations (ODEs). The methods are constructed geometrically from an exponentially fitted osculating parabola. The accuracy and stability of the proposed variants is discussed and their applicability to some initial value problems is...

The emerging contaminants are commonly derived from municipal, agricultural, and industrial wastewater sources and pathways. These compounds are polar and poorly biodegradable. The dynamic removal of atenolol from aqueous solutions by activated carbon in fixed bed column systems was investigated. As far as we know, this is the first study reporting the decontamination by adsorption in fixed bed...

The endothelium is an active organ with paracrine-endocrine capabilities that directs a multitude of physiological actions both locally and remotely. Cardiac arrest and resuscitation is a model of whole body ischemia reperfusion injury, interventions that have their basis in cytoprotection, reduction of the inflammatory cascade, fibrinolysis and improvement of microvasculature blood flow target...

The change point model (CPM) framework introduced in Hawkins, Qiu, and Kang (2003) and Hawkins and Zamba (2005) provides an effective and computationally efficient method for sequentially detecting multiple changes points in streams of Gaussian random variables, when no information is available regarding the parameters of the distribution in the various segments. It has since been extended in v...

in this paper, front engine accessory drive (fead) system of automotive engine is modeled with adams software. the model is validated using engine test data. it is then used to investigate the effect of design parameters on the system performance such as belt vibration and loads on the idlers. three alternative layouts were developed in order to improve the performance of original eead system. ...
