In this paper, a minimum and near-minimum time optimal control laws are developed and compared for a rigid space platform with flexible links during an orientating maneuver with large angle of rotation. The control commands are considered as typical bang-bang with multiple symmetrical switches, the time optimal control solution for the rigid-body mode is obtained as a bang-bang function and app...

STUDY OBJECTIVE The Epworth Sleepiness Scale (ESS) has been used to detect patients with potential sleep disordered breathing (SDB). Recently, a 4-Variable screening tool was proposed to identify patients with SDB, in addition to the STOP and STOP-Bang questionnaires. This study evaluated the abilities of the 4-Variable screening tool, STOP, STOP-Bang, and ESS questionnaires in identifying subj...

Study background: Obstructive sleep apnoea may be one of the few reversible causes of cognitive impairment. Hence its reliable identification in patients referred to dedicated cognitive disorders clinics is important. Method: STOP-Bang, a validated questionnaire for obstructive sleep apnoea, was administered to consecutive new patients attending a dedicated cognitive disorders clinic based in a...

Objective: To translate and perform a cross-cultural adaptation of the Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and Gender (STOP-Bang) questionnaire so that it can be used as a screening tool for the diagnosis of obstructive sleep apnea in Brazil. Methods: Based on the principles of good practice for the translation and cross-cultural ...
