This paper deals with the problem of nonlinear uncertainties when tracking an infrared dim small target fast maneuvers. The particle filter (PF)-based methods are mostly considered. existing improvement for PF can handle conventional maneuver, motion state which changes slowly and in most cases is assumed to be linear. However, maneuvers appear on target, PF-based method will soon suffer from d...

Objectives To evaluate the feasibility of ΔP and Pplat continuous monitoring during volume (VCV) and pressure (PCV) controlled ventilation, we compared with gold standard (occlusion maneuvers at end-inspiration and end-expiration) two different methods: 1Least Square Fitting (LSF) method that provide maneuver-free Pplat and ΔP values; 2Mini Occlusion (MO) method by performing brief occlusion ma...

BACKGROUND The measure of the maximal expiratory pressure (MEP) has some contraindications, as it is believed that the responses obtained in this measure are similar to the Valsalva maneuver (VM). OBJECTIVE The main purpose of this study was to evaluate the heart rate responses (HR) during the MEP and the VM measures in healthy young men into different postures aiming to identify whether and ...

The aim of this classic paper by Paul Webb (Webb, 1976) was to investigate the effect of size on fast-start performance and to use the results in order to make some theoretical considerations on predator–prey interactions. Until the 1970s, most work on fish swimming had focused on steady conditions, with the goal of studying the relationship between the energetics, performance and kinematics of...

The injurious effects of alveolar overdistention are well accepted, and there is little debate regarding the importance of pressure and volume limitation during mechanical ventilation. The role of recruitment maneuvers is more controversial. Alveolar recruitment is desirable if it can be achieved, but the potential for recruitment is variable among patients with ARDS. A stepwise recruitment man...
