Frictional resistance comprises more than 60% of the total resistance for most merchant ships.Active and passive devices have been here used to reduce frictional resistance, but the most effective and practical device is an air lubrication system.Such systems have been applied in several ships, and their effects have been verified in sea trials.On
Over the last half century, neuropsychologists, cognitive psychologists and cognitive neuroscientists interested in human memory have accumulated evidence showing that there is not one general memory function but a variety of memory systems deserving distinct (but for an organism, complementary) functional entities.The first attempts to organize me
The availability of low-cost unmanned aerial vehicles (UAVs), or drones, has made their organisation in fleets more feasible.The required coordination for managing these fleets comes with an increased complexity.When used for long-durability, autonomous inspection missions, it is necessary to recharge the drones due to their limited battery capacit
Frost is a natural disaster here that can cause catastrophic damages in agriculture, while traditional temperature monitoring in orchards has disadvantages such as being imprecise and laborious, which can lead to inadequate or wasteful frost protection treatments.In this article, we presented a heating requirement assessment methodology for frost p
