in this paper, the problem of finite time stabilization for guidance system is investigated and a novel nonlinear guidance law against maneuvering targets is proposed based on the principles of parallel navigation. the proposed law is developed using two variable structure control techniques. by applying finite time integral sliding mode and combining it with terminal sliding mode, a new guidan...

Alveolar collapse is a common problem in mechanically ventilated children, particularly those with significant lung disease, such as ARDS. Many different methods are used by clinicians to recruit collapsed alveoli, including sustained inflation or incremental increases in PEEP until recruitment is achieved. These methods have primarily been studied in animal models and adults with varying appro...

OBJECTIVE To assess the efficacy of obstetric maneuvers for resolving shoulder dystocia and the effect that these maneuvers have on neonatal injury when shoulder dystocia occurs. METHODS Using an electronic database encompassing 206,969 deliveries, we identified all women with a vertex fetus beyond 34 0/7 weeks of gestation who incurred a shoulder dystocia during the process of delivery. Wome...

dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. this study is aimed to elaborate this notion in the case of three dimensional (3d) walking and extend it f...

Control interfaces provide the most tangible connection between human users and computer software. This link is especially important in interactive real-time applications, like games and simulations, because users desire efficient controls that allow them to maximize their interactivity and immersion with the software. Traditionally, interfaces have been largely limited to keyboards and mice. R...
