This paper deals with the challenging aspect concerning the state estimation in hydraulic actuators characterized by not negligible nonlinearities. Particularly,. One of the most common hard nonlinearities in hydraulic actuator is the deadzone. More specifically, dead-zone occurs in hydraulic control valves when its spool occludes the orifice with an overlap, so that for a range of spool positi...

Staphylococcus aureus is the most common cause of hospital-acquired infection. Because of the emergence of antibiotic-resistant strains, these infections represent a serious public health threat. To develop a broadly protective vaccine, we tested cell wall-anchored surface proteins of S. aureus as antigens in a murine model of abscess formation. Immunization with four antigens (IsdA, IsdB, SdrD...

To ensure safe operation of unmanned aerial vehicles (UAVs), component hazards need to be dealt with robustly through effective fault diagnosis. The extended Kalman filter (EKF) has proven popular in this realm, though it is known to suffer from linearisation errors that can degrade performance. This paper presents results from initial simulation trials that address sensor fault detection and i...

We formulate an infinite-time quadratic functional minimization problem ofAedes aegyptimosquito population.Three techniques of mosquito population management, chemical insecticide control, sterile insect technique control, and environmental carrying capacity reduction, are combined in order to obtain the most sustainable strategy to reduce mosquito population and consequently dengue disease. Th...

Extended linearization is the process of factoring a nonlinear system into a linear-like structure x = A(x)x + B(x)u which contains state-dependent coefficient (SDC) matrices. An extended linearization control technique is any technique which (a) treats the SDC matrices A(z) and B(x ) as being constant and (b) uses a linear control synthesis method on the linear-like structure to produce a clos...

This paper investigates the inspection-of-pipe topic in a new framework, by rotation around pipe, peculiar to industrial sites and refineries. The evolution of ultimate system requires prototype design preliminary tests. A benchmark has been designed built mimic with main purpose assessing different types rotors control systems. presents mechatronics package including mechanical machining, elec...
