A model-based approach to detect and isolate non-concurrent multiple leaks in a pipeline is proposed, only using pressure and flow sensors placed at the pipeline ends. The approach relies on a nonlinear modeling derived from Water–Hammer equations, and related Extended Kalman Filters used to estimate leak coefficients. This extends former results developed for the single leak case, but with the...

background: aluminum phosphide is the common cause of poisoning in adults in india, with a very high case fatality ratio. we studied five patients of aluminum phosphide poisoning with polyserositis. methods: we enrolled all patients with aluminum phosphide poisoning presenting to emergency medical department, at a tertiary care hospital in northwestern india from january to july 2006. these pat...

BACKGROUND Noninvasive ventilation (NIV) is usually applied using bi-level positive airway pressure devices, and many of these devices use a single-limb patient circuit with an integrated leak port to purge the circuit of exhaled carbon dioxide. Sometimes bronchodilator therapy is indicated in pediatric patients, but there have been no studies of the optimal nebulizer position, with respect to ...

OBJECTIVE The objective of this study was to compare the air leak duration of two regulated chest tube modes following pulmonary lobectomy. METHODS This is a prospective randomized trial on 100 consecutive pulmonary lobectomies (2010-11) performed for lung cancer. A single 24-French chest tube was connected to an electronic system capable of maintaining the pleural pressure within preset valu...

OBJECTIVES During noninvasive positive pressure ventilation (NPPV), the gas leak that commonly occurs around the mask can render NPPV ineffective. We evaluated the effects of gas leak on inspiratory trigger function during NPPV with bilevel pressure and ICU ventilators. In addition, we evaluated the effects of gas leak on fraction of inspired oxygen (Fio(2)) and humidification. METHODS Air le...

OBJECTIVE Prolonged air leak is still one of the most frequent complications after pulmonary resections, particularly upper lobectomy. This study aimed at evaluating the efficacy of pleural tenting in decreasing air leak after upper lobectomy. METHODS This was a prospective randomised study of 48 patients who had upper lobectomy. They were divided into two groups: the first group included 23 ...

This position paper describes the attempt to automate the statistical approach for memory leak detection in JavaTM applications. Proposed system extends the basic statistical memory leak detection method with further intelligence to pinpoint the source of the memory leak in the source code. As the method adds only small overhead in runtime it is designed to be used in production systems and wil...

In this project we implemented Leak Finder, a tool for examining how Android applications use their granted permissions. Leak Finder instruments Android applications with custom log code, then it collects the logs from actual user application runs and uses these logs to create an execution graph. Auditors can use the executing graph to examine when an applications tends to use its permissions. ...

Background: Roux-en-Y gastric bypass is the main type of bariatric surgery. The most formidable and severe complication in morbid obesity patients after gastrojejunostomy leak. Aim: to study possibilities improving treatment outcomes obese during leak surgery using new minimally invasive methods. Methods: This retrospective cohort descriptive included all with treated Department Surgery Federal...

BACKGROUND The differentiation of the nature of a fluid collection as a complication of kidney transplantation is important for management and treatment planning. Early and delayed radionuclide renography can play an important role in the evaluation of a urine leak. However, it is sometimes limited in the evaluation of the exact location and extent of a urine leak. CASE PRESENTATION A 71-year...
