background the number of laparoscopic procedures done each year continues to rise substantially. clinically significant hemorrhage from secondary port sites at laparoscopy is an uncommon but serious complication and can become unrecognized intraoperatively. abdominal wall hemorrhage and bruising may complicate laparoscopic operative procedures. methods we propose an easy technical gesture to st...

Abstract Two methods for extraction of the effective tensor surface impedance representing metasurfaces with printed elements and arbitrary geometry are presented. The can be modelled as a shunt admittance on transmission line. extracted combined line theory enables to compute easily efficiently coefficient through multilayer metasurface structure. modelling conduct multi‐parameter study reflec...

The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...

In the last years the use of the so-called bag-of-features approach, often referred to also as the codebook approach, has extensively gained large popularity among researchers in the image classification field, as it exhibited high levels of performance. A large variety of image classification, scene recognition, and more in general computer vision problems have been addressed according to this...
