The economic and environmental losses due to serious leakage in the urban water supply network have increased the effort to control the water leakage. However, current methods for leakage estimation are inaccurate leading to the development of ineffective leakage controls. Therefore, this study proposes a method based on the blind source separation theory (BSS) to calculate the leakage of water...

one of the important factors influencing outdoor insulators performance is pollution phenomenon. the pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of leakage currents (lc) on the insulator surface, which may result in total flashover. the lc characteristics are affected by parameters such as nature and severity of pollution. loca...

introduction: video-assisted thoracic surgery (vats) is now commonly used for primary spontaneous pneumothorax. in the present study we compared the outcomes of this technique with those obtained by conventional thoracotomy.material and methods: in this cross-sectional stud, forty patients were enrolled into two groups: vats (n=20) and thoracotomy (n=20). in both groups the blebs were resected ...

Leakage resilient cryptography designs systems to withstand partial adversary knowledge of secret state. Ideally, leakage-resilient systems withstand current and future attacks; restoring confidence in the security of implemented cryptographic systems. Understanding the relation between classes of leakage functions is an important aspect. In this work, we consider the memory leakage model, wher...

Chylous leakage is a rare complication after major abdominal operations and is characterized by the collection of chylous fluid in the peritoneal cavity. Postoperative chylous leakage mainly develops as a result of surgical trauma to lymphatic channels such as lacteals, tributaries or the main lymphatic duct itself and cysterna chyli. It could be either a localized chylous leakage or diffused c...

BACKGROUND Liver involvement in acute dengue infection is frequently observed and sometimes leads to acute liver failure, with fatal outcomes. Many factors are thought to contribute to liver dysfunction, including hypoxic injury due to decreased perfusion, direct damage by the virus and immune mediated injury. In this study, we sought to identify the pattern in the change in liver enzymes throu...

Aiming to solve the problems of poor uniformity seed flow discharge and serious damage traditional straight grooved wheels improve performance air-assisted maize high-speed precision metering devices, a staggering symmetrical spiral feeding wheel with seeds was designed. To explore influence groove inclination angle length staggered feed on discharge, l ρ were used as experimental factors, vari...
