Abstract A thorough understanding of droplet impact and freezing is vital in preventing ice accretion on many outdoor devices.This simulation-based study investigated the effect of surface morphology on the impacting-freezing process of a supercooled droplet.Also, the variations of Weber number and supercooling temperature were studied numerically.

A demonstrated hybrid method based on Blender Parts and Accessories the combination of half-space physical optics method (PO), graphical-electromagnetic computing (GRECO), and Monte Carlo method on echo signals from low-flying targets based on actual environment for airborne radar is presented in this paper.The half-space physical optics method , c

Abstract Background Limb salvage surgery is an important method for treating malignant tumors of the bone involving the adjacent parts of the major joints in children.This technique allows for preservation of limb function, especially in the lower limb.However, the reconstruction of the proximal end of the tibia after removing the tumor mass with B

This article reviews the current status of tropical glaciers in the South American Andes, East Africa, and Australasia by shedding light on past, present, and future glacier coverage in the tropics, the influence of global and regional climates on the tropical Lens Cleaner glaciers, the regional importance of these glaciers, and challenges of ongoi

In the aftermath of a large-scale emergency, Unmanned Aerial Vehicles (UAVs) can play a key role as mobile communication systems supporting rescue operations on the ground.At the same time, the deployment of autonomous UAV swarms still poses severe challenges in terms of distributed mobility, swarm connectivity and mesh networking.To this purpose,
