Digital computers use numbers based on flawed representations of real numbers, which may lead to inaccuracies when simulating the motion of molecules, weather systems and fluids, find scientists.
Read moreIdentifying geological features in a densely vegetated, steep, and rough terrain can be almost impossible. Imagery like LiDAR can help researchers see through the tree cover, but subtle landforms can often be missed by the human eye.
Read moreThis study aimed to propose a new method for a bi-objective optimization. Ten student participants used a touch screen at 3 different installation heights, 3 tilt angles and with 3 button sizes. The joint angles, while using a touch screen, were measured to estimate physical workload. With the subjective screen visibility determined, the Pareto optimal solution showed ranges of 1124-1251 mm height and 44.4-67.9° tilt angle for the optimal installation of touch screens.
