OBJECTIVE A Valsalva maneuver is used clinically and on imaging in order to determine female pelvic organ prolapse. We have examined the potential confounding effect of levator co-activation at the time of a Valsalva maneuver and the impact of repetition with biofeedback instruction. METHODS Fifty nulliparous women at 36-38 weeks' gestation received 3D/4D translabial ultrasound investigation ...

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 ...

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...

background: sellick's maneuver (cricoid pressure) may make laryngoscopic view and tracheal intubation more difficult. this study compared the different techniques of cricoid pressure (cp) regarding to the laryngoscopic view and time to intubation. methods: in142 anesthetized patients, 4 types of cp was randomly applied; a) one-handed cp using thumb, index and middle fingers, b) one-handed cp us...

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...

In this Letter, we present the third kind of Darboux transformation of the classical Boussinesq system, and discuss its relationship with the two basic Darboux transformations. By applying the Darboux transformations, we obtain the solutions of multiple soliton interactions, including overtaking and head-on collisions.  2001 Published by Elsevier Science B.V.

A study is made of an overtaking optimal problem for a population system consisting of two competing species, which is controlled by fertilities. The existence of optimal policy is proved and a maximum principle is carefully derived under less restrictive conditions. Weak and strong turnpike properties of optimal trajectories are established. © 2007 Elsevier Inc. All rights reserved.

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...

This study was designed to detect the sensitivity of different methods of eliciting knee jerks and to compare the conventional methods with the newly purposed maneuver. Knee jerk (a deep tendon reflex) was elicited in 123 apparently normal population (77 males and 46 females) with three different methods (1) without applying reinforcement, (2) applying Jendrassik maneuver (strong voluntary cont...

Maneuver Regulation, Transverse Feedback Linearization and Zero Dynamics Christopher Nielsen Masters of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2004 The maneuver regulation (or path following) problem has received considerable attention in the control literature where feedback linearization has proven an effective approach to solving the ...
