During product design, the design office defines dimensional and geometrical parameters according to the use criteria and product functionality. The manufacturing department must integrate the manufacturing and the workpiece position dispersions during the choice of tools and the machine operating modes and parameter values to respect the functional constraints. In this article, the authors sug...

For persons with severe disabilities, a brain-computer interface (BCI) may be a viable means of communication. Lapalacian electroencephalogram (EEG) has been shown to improve classification in EEG recognition. In this work, the effectiveness of signals from tripolar concentric electrodes and disc electrodes were compared for use as a BCI. Two sets of left/right hand motor imagery EEG signals we...

abstract introduction: interferential current is one of the most popular kinds of electrical stimulation that are used in electrotherapy. despite its clinical popularity, there have been limited studies to investigate how this stimulation protocol affects the nerve fibers. this study was aimed to develop a realistic model for the stimulation of nerve fibers by interferential currents and using ...

PURPOSE To investigate whether the multifocal visual evoked potential (mVEP) is dependent on the electrode position, and to confirm the reproducibility of the mVEP. METHODS The mVEPs were recorded using the Veris III system with two different bipolar electrode settings. In Position 1, electrodes were placed at equal distances in vertical alignment 2 cm above and below the inion. In Position 2...

This paper presents a method to estimate geometrical, photometrical, and environmental information of a singleviewed object in one integrated framework under fixed viewing position and fixed illumination direction. These three types of information are important to render a photorealistic image of a real object. Photometrical information represents the texture and the surface roughness of an obj...

Manufacturing tolerancing is intended to determine the intermediate geometrical and dimensional states of the part during its manufacturing process. These manufacturing dimensions also serve to satisfy not only the functional requirements given in the definition drawing, but also the manufacturing constraints, for example geometrical defects of the machine, vibration and the wear of the cutting...

The one-stage electrohydrodynamic (EHD) pumps with electrodes “a diaphragm – a plate hole” and wire are studied. It is established that the help of flow-limiting diaphragms, pump characteristics can be significantly improved. indicated in main multi-stage EHD pumps, it preferable to use lattice-type made bare perforated insulated wires. Optimal geometrical parameters electrodes, dielectric coat...

BACKGROUND Freehand 3D ultrasound is a powerful imaging modality with many potential applications. However, its reliance on add-on position sensors, which can be expensive, obtrusive and difficult to calibrate, is a major drawback. Alternatively, freehand 3D ultrasound can be acquired without a position sensor using image-based techniques. Sensorless reconstructions exhibit good fine scale deta...
