The X-ray microbeam method for measurement of articulatory dynamics has been used to acquire large amounts of data, with reduced X-ray dosage, resulting in one of the most widely used freely available speech production databases. The Xray Microbeam Speech Production Database (XRMB-SPD), developed at Wisconsin University, USA, includes a vast amount of coordinate data describing articulatory mov...

Magnetic Resonance Imaging (MRI) is increasingly being used for improving tumor delineation and tumor tracking in the presence of respiratory motion. The purpose of this work is to design and build an MR compatible motion platform and to use it for evaluating the geometric accuracy of MR imaging techniques during respiratory motion. The motion platform presented in this work is composed of a mo...

This paper presents a new six degree-of-freedom parallel mechanism platform, which can be used as a basis for general motion simulators. The unique feature of the platform is that it enables unlimited continuous 360-degree spin in any rotational axes plus finite X, Y, and Z-axis translation motion. The first part of the paper deals with the kinematic design issue of the platform including singu...

The report AGARD-AR-144 provides a framework for systematically assessing the dynamic characteristics of flight simulator motion systems. Several measurements defined in the report were performed on the Stewart platform located at the Max Planck Institute for Biological Cybernetics. The measurements were performed with a setup consisting of real-time hardware and an off-the-shelf IMU. Results i...

A mobile manipulator is defined as a robotic system composed of a nonholonomic mobile platform and a holonomic manipulator fixed to the platform. The kinematics of the mobile manipulator, describing velocity constraints imposed on the platform and determining actual position and orientation of the end effector, are represented by a driftless control system with outputs. The motion planning prob...

An on-grid floating desalination plant (FDP), powered by conventional fossil fuel, was recently proposed to support freshwater demands in some remote coastal cities that have electricity grid networks. The aim of this study is investigate feasibility integrating a wind turbine into the same FDP platform be suitable for off-grid services with sustainable clean energy resources. new concept fully...

This paper introduces Pervaho, a platform for developing and testing mobile ad hoc applications. Such applications exhibit an inherently here & now nature, i.e., they only execute when adequate conditions are met right here and right now. For this reason, the Pervaho platform is founded on a location-based publish/subscribe service. This first cornerstone of our platform allows mobile peers to ...

Nowadays, driving simulators are interactive virtual reality tools which take a considerable place in the human factors studies. The difficulty or impossibility to reproduce in reality some road situations mainly for risk and reproducibility reasons increases the interest of this tool. Nevertheless, the validation of the experiments carried out on driving simulator is closely related to embeddi...
