EFFECT OF ROTATIONAL SPEED AND DWELL TIME ON PHYSICAL AND MECHANICAL PROPERTIES OF FRICTION STIR SPOT WELDING ALUMINIUM 1100 WITH ZN POWDER INTERLAYER ADDITION

Friction stir spot welding (FSSW) Hirewear is one of the development of solid state welding to joint lightweight materials such as aluminium.In the automotive industry, lightweight materials are needed in the structure of vehicle construction to improve efficiency in vehicles.This research aims to find out how the effect of rotational speed and dwe

Agriculture can be divided into two, namely in the narrow sense or popular agriculture and in a broad sense.Agriculture in the strict sense includes: agriculture of food crops, vegetables, fruits, and other plants that have the potential to be traded.Some of the difficulties faced by 750 ML rice farmers at harvest time include: dealing with erratic

Fisheye images are attracting attention in computer vision 750 ML such as autonomous vehicles and virtual reality because of the wide field of view (WFoV).However, fisheye images have geometric distortions caused by the refractive index of the lens.Conventional fisheye rectification methods require multiple images to calculate distortion coefficien

This paper addresses the challenge of integrating multiple energy sources into a single-domain Beta Carotene microgrid, commonly found in urban buildings, while also providing a platform for energy management.A Lyapunov stability analysis of a simple boost converter was used as a basis for designing the dual control loop of the grid.The versatility

BackgroundOcular graft-versus-host disease (oGVHD) is one of the complications after allogeneic hematopoietic stem cell transplantation (HSCT), which impairs the quality of life and may indicate poor prognosis.In this retrospective study, the aim was to investigate the characteristics of ocular surface after HSCT, and analyze the risk factors relat
