A novel illumination normalisation (IN) method using a convolutional neural network (CNN) is proposed. The proposed network is composed of the local pattern extraction (LPE) and illumination elimination (IE) layers. The LPE layers model the relationships between the pixels in each local region in order to handle various types of local shadow and shading in the face image. Based on the commonly used...
The Smart Grid resilience in power systems could be improved thanks to remote monitoring of civil structures existing at concrete and earth-filled dams, which indicates any atypical behavior of these structures. Among the various sensors and transducers used, the direct and inverted pendulums present an additional challenge. These instruments are widely used in hydroelectric reservoirs to monitor...
Using a novel interatomic force field, called MMP, we study the morphology of Graphene layers under a variety of strain conditions. We report that strain induced ripples possess the “right” kind of elastic deformation that is necessary in order to produce appreciable bandgap opening, which we calculate using Tight Binding, even for low enough strain that can be accessed through realistic means. At...
In the past decade ZnO nanowires have been the key enabling material for demonstrating novel electronics components in the field of piezotronics and in the first realization of a nanogenerator. What are the materials that will be crucial in demonstrating even more novel devices in future years? We propose the use of both core shell nanowires and graphene as key enablers of new functionalities.
One of the barriers in remote operation of circuit-switchers installed in subtransmission lines is to be aware of the actual conditions of each of the poles of the circuit-switcher, as well as confirmation of the success, or failure, of the operation. Often the visual confirmation of the maneuver is part of the procedure, requiring the displacement of the ground crew and creating schedule delays....
Pulse modulation technique was applied for microwave excited atmospheric pressure air and Ar plasmas with fixed average power. Breakdown and sustain powers were measured and UV-Vis emission spectra were observed. As the duty ratio decreased, pulse modulated plasmas showed enhanced results as compared to continuous signal excited plasmas. Breakdown powers of both of air and Ar plasmas were reduced...
This paper describes the upgraded portable test bench for the Tile Calorimeter of the ATLAS experiment at CERN. The previous version of the portable test bench was extensively used for certification and qualification of the front-end electronics during the commissioning phase as well as during the short maintenance periods of 2010 and 2011. The new version described here is designed to be an easily...
For the remote operation of transmission line circuit-switchers that are equipped with electric arches extinction chamber must be known the signal provided by mechanical flags that signalizes the status of SF6 gas pressure as well the state of the electrical contact inside of the chamber. This visual inspection required is costly and may generate delays, reducing the availability of the equipment...
The authors report on one-dimensional (1D) aluminium oxide (Al2O3) nanoflakes fabrication on hollow periphery by using a simple hydrothermal corrosion method on the aluminium foil. The authors used the electrospun poly(acrylnitrile) (PAN) nanofibres as a template on aluminium foil to obtain 1D Al2O3 nanoflakes structure. Two important experimental parameters were governed in forming the 1D Al2O3 nanoflakes;...
