During liver resection clamping of the hepato-duodenal ligament (the Pringle maneuver) is performed to reduce intraoperative blood-loss. During this maneuver acute portal hypertension may lead to spontaneous splenic rupture requiring rapid splenectomy in order to control blood loss. We present 2 case of patients with hemorrhage from the spleen during clamping for liver surgery. A review of the ...

Particle filter is proposed for tracking a torpedo using bearings-only measurements when torpedo is attacking an ownship. Towed array is used to generate torpedo bearing measurements. Ownship evasive maneuver is used for observability of the bearings-only process. Particle filter combined with Modified Gain Bearings-Only Extended Kalman Filter is used to estimate torpedo motion parameters, whic...

The epididymis is the most common source of acute and chronic scrotal pain in the outpatient setting, yet there are no standardized methods for proper palpation of this organ. We describe a novel scrotal examination technique that is reproducible and easy to learn. Our technique utilizes a maneuver we call testicular 'framing', and in our experience this maneuver almost invariably leads to prop...

This paper proposes a multiple-model (MM) hypothesis testing approach for detection of unknown target maneuvers that may have several possible prior distributions. An MM maneuver detector based on sequential hypothesis testing is developed. Simulation results that compare the performance of the proposed MM detector to that of traditional maneuver detectors are presented. They demonstrate that t...

To the Editor: Abdominal compression is a maneuver that is often applied in manually assisted coughing1 to aid patients with mainly neuromuscular disease whose cough is inadequate for removing bronchial secretions.2 We report the case of a woman who was tetraplegic secondary to transverse myelitis. Her caregivers provided manually assisted coughing for years but the maneuver was apparently rela...

This research studies the overtaking maneuver in some representative situations. A simulator using Matlab Simulink connecting its outputs to a Virtual Reality module to show the complete overtaking performance from all points of view has been made. With this useful tool the parameters of the car controllers and decision making systems can be set up, and unforeseen new features of the overtaking...

In this paper, experimental verifications of various jerk-limited control designs are presented. The focus is on a large slew maneuver of a flexible spacecraft where the fast and accurate pointing is required at the end of the maneuver. Various control profiles are investigated including input shaping and jerk-limited optimal control profiles, especially to account the effect of jerk in the con...

In 14 consecutive patients with varying myocardial function, evaluation of the Valsalva maneuver was performed using aortic pulse pressure decay to investigate a possible quantitative relationship between the pattern of response and the degree of myocardial dysfunction. The aortic pulse pressure response during strain correlated with resting left ventricular end-diastolic pressure and pulmonary...
