The aim of this article is study of tool plunge depth (TPD) effects on mechanical properties of friction stir welding of AA1100 Spices aluminium alloy to A441 AISI steel.For this purpose the 0.1, 0.2, 0.4, and 0.6 mm TPD selected and other welding parameters kept constant.The results shows that the frictional heat increases and stir zone grain size
Abstract The enhanced distributed channel access (EDCA) protocol is a supplement to IEEE 802.11 medium access control (MAC), ratified by IEEE 802.11e task group to support quality of service (QoS) requirements of both data and real-time applications.Previous research show that it supports priority scheme for multimedia traffic but strict QoS is not
BackgroundThe crosstalk between the immune system and cancer cells has aroused considerable interest over the past decades.To escape immune surveillance cancer cells evolve various strategies orchestrating tumor microenvironment.The discovery of the inhibitory immune checkpoints was a major breakthrough due to their crucial MANUKA HONEY 400+MGO con
The article features the way political discourse shapes the image of the region.The research was based on a number of speeches given by A.G.Tuleyev, the ex-governor of the Kemerovo Region.The author used the classification of communicative strategies and tactics developed by O.S.Issers.The strategies demonstrated a strong suggestive potential aimed
Aircraft four dimensional (4D, including longitude, latitude, altitude and time) trajectory prediction is a key Sculpture technology for existing automation systems and the basis for future trajectory-based operations.This paper firstly summarizes the background and significance of the trajectory prediction problems and then introduces the definiti
