Size-selectivity of fishing gear is an extensively studied area in fisheries sciences due to the simple fact that most modern fisheries aim at improving gear-selectivity to minimize by-catch, catches of undersized fish and to maximize catch per unit effort (CPUE) for target species.
It will also be used to help fishers adopt improved gear to reduce discards.
Furthermore, the results also show that it is advantageous to improve gear dynamics with decreasing fractal dimension, reducing time-variant stiffness and increasing damping ratio.
The theory in this paper shows a new method to analyze the gear dynamics in respect of the changing backlash and as well as builds an indirect relationship between gear dynamic performance and tooth surface characters, which can be utilized to improve gear dynamics characters through guiding gear surface design and manufacture in the future.
Epic has improved Gears 2 with subtle differences that make it standout from the original and a much better story (be it a sappy one that focuses on Dom…), but I have to say that everything about the game seems more refreshed and 10x better.
A model trawl was then built and tested in a flume tank, which provided the basis for improving the gear design.
That and improving the Gear's battery life — which has apparently been boosted to up to six days for light usage, or two to three for normal usage (a 3x increase over the first-gen device, according to Samsung).
Because these species travel so far, there is a greater chance they will encounter threats," said Hammill who noted that coastal birds "in some cases" are doing better because of improved management of breeding areas and improved fishing gear.
Records show that since it was announced the Nato conference would be held in Chicago, police have purchased improved riot gear for both officers and horses.
The surveillance techniques offered by closed circuit television, sophisticated long-distance filming, computerised identification and improved riot gear, mean that the old street battles are less common and have been replaced by containment.
