Soma Farag  Medical Department at Imperial College, London University, London, UK I read with interest the study by Khan and Arsanious1 which gave insight into the perception of the severity of medical errors of practitioners of different grades and believed that there is much to be gained from it.Medical error in the duration of one&rsqu

Designing of a sliding mode Wall Cabinet observer was finished based on the motion model of autonomous underwater vehicle (AUV).A Flutter decrease strategy for the sliding mode observer was discussed and the sliding mode observer was applied to the fault diagnosis of the AUV.Simulation experiment without faults was designed.Simulation experiment of

Big leaf mahogany (Swietenia macrophylla, King) is a valuable Neotropic timber species.It is the first extensively traded timber species to be listed in Appendix II of the CITES in 2002.The tree was introduced to India in 1795 and Kerala in 1872.The present study aimed at selecting plus trees of Swietenia macrophylla and evaluating their genetic va

In utilizing a variable-structure multiple-model (VSMM) algorithm for kinematic state estimation, the core step is the model set design.This study aims to refine the existing expected-mode augmentation (EMA) algorithm, a method of model set design.First, the OTSU algorithm is employed to determine an adaptive threshold, which in turn allows for a r

The design features of the grinding devices that implement the impact destruction of the ferromagnetic materials particles in a magneto vibrating layer formed in a non-uniform magnetic field are considered.It is shown that when a magnetizable powder is affected by an alternating magnetic field with certain parameters, a magneto vibrating layer is f
