Edge detection is the basis of many computer vision applications. State art predominantly relies on deep learning with two decisive factors: dataset content and network architecture. Most publicly available datasets are not curated for edge tasks. Here, we address this limitation. First, argue that edges, contours boundaries, despite their overlaps, three distinct visual features requiring sepa...

Unresolved pressure fluctuations at the sub-grid scale (SGS) level of large eddy simulation (LES) or Reynolds-averaged Navier–Stokes computations affect cavitation inception predictions, as SGS low pressures are simply ignored. We present a framework to take unresolved flow into account. Representing canonical turbulence, in this paper, homogeneous isotropic turbulence (HIT), fluctuations, and ...

The 2012 Lasker-DeBakey Clinical Medical Research Award will be conferred on Thomas Starzl of the University of Pittsburgh School of Medicine in Pittsburgh, Pennsylvania, USA and Roy Calne of the University of Cambridge in Cambridge, UK. They are recognized for pioneering the development of liver transplantation, an intervention that saves 20,000 lives world-wide each year.

Radio spectrum has increasingly become a strategic scarce resource in the digital world. The demand for pervasive wireless connectivity has exploded driven by smart devices and the consumption of video and Internet on the move as well as innovative services in various sectors such as transport, healthcare or energy. The Digital Agenda for Europe (DAE) and the Radio Spectrum Policy Programme (RS...

It is a pleasure to introduce this issue on electron transfer processes. The field has developed greatly and in many different directions not envisioned in the late 1940s. The modern electron transfer era began at that time in the form of studies on the simplest class of reactions in all of chemistry, isotopic exchange reactions of the electron transfer type. In their simplest form no chemical ...

Soot volume fraction and number density in a turbulent diffusion flame burning kerosene/air were predicted using two approaches. The first used a conventional soot inception model based on the acetylene concentration and is referred to as the acetylene model. The second used a soot inception model based on the formation rate of three and two ring aromatics [1] and is referred to as the PAH ince...

Weibull distribution has been used widely by many researches around the world especially in the analysis of high voltage experimental data. Unfortunately, the statistical techniques used to analyse the high voltage experimental data are not highly accurate. In view of the foregoing, this paper presents a new statistical approach to analyze the tree inception voltage of silicone rubber and epoxy...
