Demersal Seining is an active fishing method applying two long seine ropes and a seine net. Demersal seining relies on fish responding to the seine rope as it moves during the fishing process. The seine ropes and net are deployed in a specific pattern encircling an area on the seabed. In some variants of demersal seining the haul-in procedure includes a towing phase where the fishing vessel mov...

An innovative downscale test rig called V-Track has been constructed for wheel-rail contact experiments under impact loading conditions. In this paper, a force measurement system termed dynamometer was developed in to measure the forces. The consists of four 3-component piezoelectric sensors and mounted between wheel assembly steel frame V-Track, enabling it forces transmitted from interface fr...

The advantages of multihulls over monohulls are better running characteristics at high speeds and a larger deck area, which is critical for passenger ships. When designing, it necessary to choose geometric parameters, include the distance between hulls. A brief description existing methods calculating towing resistance multihull vessels provided in paper. New results an experimental study effec...

The main target of the present work is to characterize effect inclusion natural sheep wool (SW) into a railway brake block composition and then compare it that set three organic fibers commonly used in friction material industry: aramid fiber (AF), cellulose (CF) polyacrylonitrile (PAN). In order achieve this, 4 versions same with fixed amount each were produced one more sample was manufactured...

This paper presents an experimental comparative study of iron losses obtained by means of the Epstein frame, Ring Core and dynamometer tests with non-oriented electrical steel samples. The comparisons are qualitative and they are intended to show the importance of carrying out other tests to evaluate electrical steels in addition to the standard Epstein frame method. In industry, complex or cos...
