Introduction: The Phoenix probe landed on the northern plains of Mars (68.2°N, 234.2°E) on May 25, 2008, and the landscape seen on the first images acquired on the surface confirmed what was already known since the HiRISE camera began scrutinizing the Martian surface with unprecedented detail, that the existence of polygonal terrains is a predominant feature in that area [1][2]. The polygons ob...

Over 50% of the total bigeye tuna (BET) landed in the Western Central Pacific Ocean is caught incidentally in the purse seine fishery and sold for canning at prices less than US$2/kg. The remainder is landed in longline fisheries directed at BET and sold as fresh or frozen tuna at prices greater than US$10/kg. The combined fishing mortality by all gears will soon reduce the BET biomass in the P...

This paper discusses recent findings in ongoing research on the visual cues that pilots use when landing airplanes. An overview is given of the many visual cues that have been proposed in literature. Some are widely accepted as ‘important cue’ in a certain phase or for a certain decision, others are controversial. Specifically the cues used to time the flare maneuver are discussed in this contr...

The Pacific coast of Colombia has some of the most extensive mangrove forests in South America. As an isolated region and one of the country’s poorest, coastal communities rely on fishing as a main source of animal protein and income. In an attempt to reverse declining trends of fisheries resources, in 2008, an Exclusive Zone of Artisanal Fishing closed to industrial fishing, was established by...

Weight-on-Wheels (WoW) systems are aimed at indicating if the aircraft weight is loading onto landing gear and its wheels, even partially. These an integral part of actuation system for safety-critical applications shall provide reliable information on actual operational status LG. That reveals vehicle in flight or ground. In this way, several kinds accidents may be prevented, relating instance...
