BACKGROUND The purpose of this study was to determine the extent to which measures of lower extremity strength and power contribute to the ability of older men and women to restore postural equilibrium using a single-step recovery following a large postural disturbance. METHODS The postural disturbance, which has been used as a surrogate for forward-directed falls, involved a sudden release f...

It is widely accepted that textureless surfaces cannot be recovered using passive sensing techniques. The problem is approached by viewing image formation as a fully threedimensional mapping. It is shown that the lens encodes structural information of the scene within a compact threedimensional space behind it. After analyzing the information content of this space and by using its properties we...

Original Equipment Manufacturers (OEM) are shifting towards remanufacturing, signalling growth in new investments remanufacturing. It is a noticeable global trend owing to the popularity of circularity and sustainability concepts, catalysed by environmental legislations profit motives. Thus, development effective business models for remanufacturing essential. However, capturing entirety compone...

n-propylsulfamic acid supported onto magnetic fe3o4 nanoparticles (mnps-psa) was investigated as an efficient and magnetically recoverable catalyst for the one-pot synthesis of substituted coumarins from the reaction of coumarin with variety aromatic aldehydes in high to excellent yield at room temperature under solvent-free conditions. the magnetic nanocatalyst can be readily recovered easily ...

Abstract A digital twin is a “live” virtual replica of sensorised component, product, process, human, or system. It accurately copies the entity being modelled by capturing information in real time, near from entity, through embedded sensors and Internet-of-Things. Many applications twins manufacturing industry have been investigated. This article focuses on, contributes to, development product...
