BACKGROUND The most appropriate lock solution for central venous access devices is still to be defined. GAVeCeLT - the Italian group for venous access devices - has developed a consensus on the evidence-based criteria for the choice and the clinical use of the most appropriate lock solution for central venous catheters (excluding dialysis catheters). METHOD After the constitution of a panel o...

Any variable frequency drive requires an efficient and controlled braking system. Therefore, different braking techniques have been the subject area of researchers to enhance the performance as well as overall life of the drives. In this paper, a literature study is made of various existing braking methods, focused on induction motor (IM) drive performance. The braking methods are compared and ...

In most studies, braking of vehicle in a straight path has been considered. When vehicle moves in a curved path, the effect of camber angle and fork angle should be considered. The variable camber angle assists braking in a curved road but the turning radius of vehicle changes due to varying camber angle and fork angle. The antilock braking system (ABS) is used for enhancing vehicle directional...

Pre-eclampsia is a vascular disorder of pregnancy where anti-angiogenic factors, systemic inflammation and oxidative stress predominate, but none can claim to cause pre-eclampsia. This review provides an alternative to the 'two-stage model' of pre-eclampsia in which abnormal spiral arteries modification leads to placental hypoxia, oxidative stress and aberrant maternal systemic inflammation. Ve...

This paper presents the formulation of a slipcontrol model for purposes of performing slip tracking of target slip. Antilock braking system modelling is performed to develop a quarter car vehicle deceleration model for braking without cornering. Input-state based feedback linearisation is applied to the highly non-linear developed antilock braking system model. Input-state feedback linearisatio...

The aircraft anti-skid braking system (AABS) plays an important role in taking off, taxiing, and safe landing. In addition to the disturbances from complex runway environment, potential component faults, such as actuators can also reduce safety reliability of AABS. To meet increasing performance requirements AABS under fault disturbance conditions, a novel reconfiguration controller based on li...
