We present a new approach for anomaly detection in the context of visual surface inspection. In contrast to existing, purely appearancebased approaches, we explicitly integrate information about the object geometry. The method is tested using the example of wire rope inspection as this is a very challenging problem. A perfectly regular 3d model of the rope is aligned with a sequence of 2d rope ...

Natural convection heat transfer from a tube bundle in the indirect water bath heaters is investigated. A computer-code is used for the solution of the governing equations of mass, momentum and energy transfer based on the SIMPLE-C algorithm. Simulations are carried out for the gas pressure station heater of Kermanshah city with various tube bundle arrangements. In order to validate the numeric...

Aims. We aim to investigate the configuration of a complex flux rope above δ sunspot region in National Oceanic and Atmospheric Administration AR 11515 its eruptive expansion during confined M5.3-class flare. Methods. studied formation using continuum intensity images photospheric vector magnetograms provided by Helioseismic Magnetic Imager on-board Solar Dynamics Observatory (SDO). employed ex...

Aboard a sailboat, when the wind changes unfavourably for our course, we can adjust the sails. We perform the operation of pulling a rope—but when the rope is fastened to the sail as a sheet, pulling the rope means adjusting the sail, while also paying attention to the wind, the sea current, the movements of the boat. The rope-with-sail is the very rope we are pulling: a sociomaterial entanglem...

One of the possible ways to transfer tractive power a drive unit traction element is use fibre friction. When steel rope used as element, there in groove created on perimeter rim driving sheave. The transmission capability directly proportional size angle wrap and shear friction coefficient surface when contact with wall. relationship for calculating grooves given by relevant technical standard...

Let us begin with definitions. Fix two points A and B in R. We shall always assume that A = (0, 0, 0) and B = (1, 0, 0) so, in particular, the line AB is the x-axis and the length of the interval [AB] is equal to 1. (We shall write [AB] for the closed interval between A and B, (AB) for the corresponding open interval, and AB for the line passing through A and B.) A rope is a non-singular C-smoo...

Bubble columns are gas- liquid contactors that are widely used in chemical and bio- chemical industries. High mixing that result in high heat and mass transfer rates are amongst their advantages. Heat transfer in a bubble column having a bundle of heaters investigated and the variation of heat transfer coefficient with variation in heaters pitch to diameter ratios in a bundle of heaters reporte...

The LASCO and EIT instruments on the SOHO spacecraft have provided an unprecedented set of observations for studying the physics of coronal mass ejections (CMEs). They provide the ability to view the pre-event corona, the initiation of the CME and its evolution from the surface of the Sun through 30 R ⊙. An example of the capability of these instruments is provided in a description of a single ...
