This paper aims is to design an integrated navigation system constituted by low-cost inertial sensors to estimate the orientation of an Autonomous Underwater Vehicle (AUV) during all phases of under water and surface missions. The proposed approach relied on global positioning system, inertial measurement unit (accelerometer & rate gyro), magnetometer and complementary filter technique. Complem...
Purpose: We evaluated the short-term effects of cobalt-60 gyro rotating stereotactic radiotherapy (gyro knife) for primary hepatocellular carcinoma (HCC) ineligible for local therapy or surgery. Methods: Between August 2010 and December 2014, gyro knife radiotherapy was used in our department of radiation oncology to treat 63 patients with HCC who met the inclusion criteria and were unable or u...
Modes and quasi-modes for mϭ1,2 are studied in a gyro-kinetic model for a pure-electron plasma. Only z-independent perturbations are considered. Numerical methods are used to solve the relevant differential equations for smooth, analytic density profiles. Different temperatures and representative profiles are considered and comparison is made with the familiar cold fluid model from which the re...
This paper presents the design and performance evaluation of a novel integrated attitude filter with application to space navigation. The design is based directly on the sensor measurements as opposed to traditional solutions that resort to rotation parameterizations. The information provided by a low-cost star tracker is merged with the measurements of a triaxial rate gyro to provide accurate ...
Some FTU plasma scenarios are characterised either by high electron temperature, produced by ECRH, or high densities, by pellet injection. This paper discusses the energy transport characteristics of these configurations and compares them with the predictions of mixed Bohm/Gyro-Bohm model that has been recently proposed. The Gyro-Bohm term of the model overestimate the measured energy transport...
Abstract In this paper, we present an analysis of the conservation currents in a full-F electromagnetic gyro-kinetic model long-wavelength limit. This equation corresponds to what is usually called ‘vorticity equation’, which not strictly correct as it cannot be formulated curl velocity equation. will therefore use term ‘current equation’ instead. Our results are relevant reduced plasma descrip...
The current GPS signal structure and signal power levels are barely sufficient for indoor applications. Recent developments in high sensitivity receiver technology are promising for indoor positioning inside light structures such as wooden frame houses but generally not for concrete high rise buildings. Errors due to multipath and noise associated with weak indoor signals limit the accuracy and...
