Problem: Leakage of the transmission fluid or oil in powertrain systems (i.e., transmissions, cylinder heads, engine blocks, etc.) can cause engine overheating and/or permanent damage. Therefore, it is crucial to run a leak test to inspect for any possible porosity in the casting parts. However, the inspection results for the amount of leakage at given testing times are sensitive to the tested ...

Many fluids transported by pipelines are hazardous. It is therefore often necessary to install leak detection (and localization) systems (LDS), especially due to legal regulations like • the “Code for Federal Regulations (CFR) Title 49 Part 195” [1], API 1130 2 Ed. [2], both for the USA, or • the “Technische Regeln für Fernleitungen” (TRFL) (Technical Rules for Pipelines) in Germany [5]. This p...

BACKGROUND One of the most serious complications after laparoscopic sleeve gastrectomy (LSG) is gastric leak. Few publications exist concerning the treatment of gastric leak. We sought to determine by way of a prospective study the clinical presentation, postoperative course, and treatment of gastric leak after LSG for obesity. METHODS From October 2005 to August 2008, 214 patients with diffe...

Objective To evaluate the risk factors and outcome of bile leak after liver transplantation. Methods We undertook a retrospective study of patients who underwent liver transplantation in our institution between January 2010 and January 2014. The characteristics and survival rate of patients with or without bile leak were compared. Results Bile leak was observed in sixteen patients after liv...

Pancreatic ascites and effusion is a challenging complication to manage, hence our aim was to evaluate the efficacy of pancreatic endotherapy in pancreatic ascites and pleural effusion. Endotherapy included endoscopic retrograde cholangiopancreatography (ERCP) with a pancreatogram and pancreatic stent placement across the leak in patients with pancreatic ascites/effusion. A total of 53 patients...

OBJECTIVE Primary closure of the dura remains difficult in many neurosurgical cases. One option for dural grafting is the collagen sponge, which is available in multiple forms, namely, monolayer collagen and bilayer collagen. Our primary goal was to assess differences in the incidence of postoperative cerebrospinal fluid (CSF) leak, including fistula and pseudomeningocele, and postoperative inf...

OBJECTIVE • To determine if the RENAL nephrometry score is associated with urine leak after partial nephrectomy for tumours ≤ 7 cm. PATIENTS AND METHODS • Thirty-one patients who developed urine leak after partial nephrectomy between 1998 and 2006 were identified. Each patient was individually matched (1 : 4 by age, gender and surgery date) to 124 patients who had undergone partial nephrectom...

Increased diastolic SR Ca2+ leak (J(leak)) could depress contractility in heart failure, but there are conflicting reports regarding the J(leak) magnitude even in normal, intact myocytes. We have developed a novel approach to measure SR Ca2+ leak in intact, isolated ventricular myocytes. After stimulation, myocytes were exposed to 0 Na+, 0 Ca2+ solution +/-1 mmol/L tetracaine (to block resting ...

This paper proposes a new framework for leak diagnosis in pipelines using leak-augmented scalograms and deep learning. Acoustic emission (AE) scalogram images obtained from the continuous wavelet transform have been useful pipeline health diagnosis, particularly when combined with However, background noise has significant impact on AE signals, which can reduce accuracy of identification classif...
