Abstract The presence of defects, such as pores, in materials processed using additive manufacturing represents a challenge during the manufacturing of many engineering components.Recently, ultrasonic vibration-assisted (UV-A) directed energy deposition (DED) has been shown to reduce porosity, promote grain refinement, and enhance mechanical perfor

During dropwise condensation on a hydrophobic surface, it is intuitively assumed that droplets will grow with time.However, it can be observed that some droplets follow an opposite fate and instead disappear.This happens, for example, close to hygroscopic particles as they alter Vacuum Flasks the local relative humidity.Here, we show that evaporati
Digital papillary adenocarcinoma (DPA) is a rare cutaneous tumor license plates originating from the eccrine sweat glands.These lesions occur almost exclusively on the digits of the hands and feet, where there is a high concentration of eccrine glands.The diagnosis is made histologically, and the course of the malignancy tends to be very aggressive
This paper deals with the stabilization of an inverted pendulum on cart; the latter is pneumatically actuated by a double acting cylinder controlled by low cost proportional valves.In particular, a numerical model of whole system is developed in order to find the amp; Reins Leather ability of the pneumatic actuation in stabilizing the pendulum and
