Conventional robots navigate much like humans do, relying on detailed maps of the area they are in to get around. This allows the robot to maintain an accurate estimate of its own location, but comes ...

Garmin Edge bike computers are one of the most popular choices for cyclists to navigate, record their rides and train more scientifically. Over time, Garmin has upgraded the capabilities of its GPS ...

The impact of meridional winds on the onset and evolution of equatorial plasma bubbles (EPBs) is reviewed. The conventional wisdom had been that transequatorial meridional winds have a stabilizing ...

The PaStiX (Parallel Sparse matriX package) is a open-source scientific library that provides a high performance parallel solver for very large sparse linear systems based on direct methods. Numerical ...

Abstract: The sailing path of an unmanned sailboat is restricted by the wind direction due to its own design characteristics, and how to choose the sailing direction correctly and reasonably is a ...

Abstract: In this paper, the UAV formation position adjustment is divided into two steps: transmitting signal UAV position adjustment and receiving signal UAV position adjustment. Using geometric ...

The Cummins equation is commonly applied to describe the motion of floating structures. Because of the convolution term, the efficiency of calculation is low and the ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

National grid bottlenecks mean lost revenues are mounting for wind industry Industry body IWEA has raised concerns over bottlenecks within Ireland’s wind energy network. Photo: Pascal ...

Limited landing area as well as interference due to wind disturbance and wave motion make shipboard landings of unmanned aerial vehicles (UAVs) extremely difficult. Use of UAVs at sea can enhance the ...
