BACKGROUND After radiotherapy to the head and neck, many patients experience swallowing difficulties. Preliminary work indicates that these patients benefit from the super-supraglottic swallow maneuver. METHODS Lateral videofluoroscopic studies examined oropharyngeal swallowing in 9 patients who suffered from dysphagia after radiation to the head and neck. Each patient completed two swallows ...

In this paper we describe the control logic that enabled a small-scale unmanned helicopter to execute a completely automatic aerobatic maneuver. The logic consists of steady-state trim trajectory controllers, used prior to, and upon the exit from the maneuver; and a maneuver logic inspired by human pilot strategies. Extensive flight tests with this control logic demonstrated smooth entry into t...

objectives comparing the effects of spontaneous pushing in the lateral position with the valsalva maneuver during the second stage of labor on maternal and fetal outcomes. methods inclusion criteria in this randomized clinical trial conducted in iran were as follows: nulliparous mothers, live fetus with vertex presentation, gestational age of 37 - 40 weeks, spontaneous labor, and no complicatio...

In this paper a novel approach for detecting unknown target maneuver using range rate information is proposed based on the generalized Page’s test with the estimated target acceleration magnitude. Due to the high nonlinearity between the range rate measurement and the target state, a measurement conversion technique is used to treat range rate as a linear measurement in Cartesian coordinates so...

UNLABELLED The use of nasopharyngoscopy during the application of intrathoracic pressure (Müller maneuver) is frequently employed to establish the site of upper airway obstruction. The Müller maneuver, however, is used when the patient is awake and therefore may not correlate with obstruction occurring during sleep. AIM To compare the degree of pharyngeal obstruction in the retropalatal and r...

OBJECTIVE To evaluate the effectiveness of the Epley maneuver compared with vestibular rehabilitation on patient-reported symptom relief and conversion of the Dix-Hallpike from positive to negative in patients with posterior benign paroxysmal positional vertigo (p-BPPV). DATA SOURCES PubMed, Embase, and the Cochrane Library. REVIEW METHODS A systematic search was conducted. Studies reportin...

Moving target cyber-defense systems encompass a wide variety of techniques in multiple areas of cyber-security. The dynamic system reconfiguration aspect of moving target cyber-defense can be used as a basis for providing an adaptive attack surface. The goal of this research is to develop novel control theoretic mechanisms by which a range of cyber maneuver techniques are provided such that whe...

The Valsalva maneuver is frequently used to test autonomic function. Previous work demonstrated that the blood pressure decrease during the Valsalva maneuver relates to thoracic hypovolemia, which may preclude pressure recovery during phase II, even with normal resting peripheral vasoconstriction. We hypothesized that increased regional blood volume, specifically splanchnic hypervolemia, accoun...

The lane change maneuver is among the most popular driving behaviors. It is also the basic element of important maneuvers like overtaking maneuver. Therefore, it is chosen as the focus of this study and novel multi-input multi-output adaptive neuro-fuzzy inference system models (MANFIS) are proposed for this behavior. These models are able to simulate and predict the future behavior of a Dri...
