Design of Sliding Mode Autopilot with Steady-state Error Elimination for Autonomous Underwater Vehicles [PDF]
, 2006 Autonomous Underwater Vehicles (AUVs) have nonlinear and time-varying behaviour and unmodelled dynamics. This paper describes the design, development and evaluation of nonlinear sliding mode autopilot system for an AUV to control the speed, steering and ...

Damage and strain rate optical characterisation of standard and tufted non crimp fabric carbon composites for Meso-scale impact models [PDF]
, 2009 As global warming is a prime concern to the wellbeing of the planet, lighter planes are a requirement to reduce CO2 emissions. Light structures made of carbon epoxy composite materials are of particular interest but are sensitive to impacts such as

A Test of Mode-Coupling Theory [PDF]
, 1990 In the history of the kinetic theory of fluids, 1969–1970 was a crucial year. In that year Alder and Wainwright [2] published a paper in which they demonstrated the breakdown of the ‘Molecular Chaos’ assumption. The Molecular Chaos assumption, originally introduced by Boltzmann as the ‘Stoszahlansatz’, states that the collisions experienced by a ...

Finite element modelling of mode I delamination specimens by means of implicit and explicit solvers [PDF]
, 2012 The simulation of delamination using the Finite Element Method (FEM) is a useful tool to analyse fracture mechanics. In this paper, simulations are performed by means of two different fracture mechanics models: Two Step Extension (TSEM) and Cohesive Zone

A Novel Vibration Mode Testing Method for Cylindrical Resonators Based on Microphones
Sensors, 2015 Non-contact testing is an important method for the study of the vibrating characteristic of cylindrical resonators. For the vibratory cylinder gyroscope excited by piezo-electric electrodes, mode testing of the cylindrical resonator is difficult.

A strong test of the dual-mode hypothesis [PDF]
Perception & Psychophysics, 2005 One account of facial cognition, the dual-mode hypothesis, maintains that there are two sources of information in a human face, featural and configural, and that these sources are processed simultaneously and independently of one another. According to the hypothesis, the processing and identification of upright faces relies primarily on configural ...
