In future burning plasma devices measuring the position and its shape with great spatial temporal resolution is a crucial task. Nowadays these information are obtained by means of magnetic coils installed inside vacuum vessel that in (like ITER DEMO), due to harsh environment caused high temperature, will experience degradation over time. Furthermore, long discharges result large integration dr...

This work is motivated by the problem of improving the accuracy of indoor ultra-wideband (UWB) position tracking through the study of the environment noise that affects such a system. Current systems can provide accuracy in the range of 30-100 cm in a small building, suitable for applications that require rough room-level precision such as asset tracking and surveillance. Our long-term goal is ...

Purpose In cardiology the angiography is a method to detect vascular stenosis by using X-ray radiation and contrast medium. There is special equipment, so called C-arms, to produce radioscopic images. An angiography system consists of an X-ray image intensifier (XRII), an X-ray source, and the mechanical structure to position the system around the patient. In general, the measurement and 3-d-re...

The robust three-dimensional position architecture is proposed in the paper, where the hybrid time difference of arrival (TDOA) and direction of arrival (DOA) position system was designed to backup the four-station TDOA position system. The digital time delay estimation (TDE) receiver is used for TDOA measurement and the cylindrical array antenna is used for DOA measurement. The general formula...

we propose a scheme for localizing an atom in a four-level configuration inside a classical standing wave field, conditioned upon the measurement of frequency of a weak probe field. in the classical standing wave field, the interaction between the atom and the field is position dependent due to the rabi-frequency of the driving field. hence, as the absorption frequency of the probe field is mea...

This paper describes progress in the design and testing of the log-ratio-based beamposition/intensity measurement module being built for the Low Energy Demonstration Accelerator (LEDA) and Accelerator Production of Tritium (APT) projects at Los Alamos National Laboratory. The VU-based module uses four, 2 MHz if inputs to perform two-axis position measurements and one intensity measurement. To c...

This paper presents a 3D particle position measurement method based on the defocusing concept introduced by A.Pentland with a single camera. Different from the existing approaches, the blur circle is used to identify the blur extent for various defocused particles, and the depth-blur relation is formulated by the modified A.Pentland mathematical formula. And, an eight-step algorithm based on Ci...

AIM The purpose of this research is to propose a procedure to measure the vertical larynx position in the neck at rest, of young adults without vocal complaint. STUDY DESIGN Transversal cohort study. MATERIAL AND METHOD A number of 68 subjects, aged between 18 to 44 years, 33 female and 35 male, participated in this study. The referential points used for this research were the right and lef...

The health care delivery system in the United States despite being one of the most technologically advanced in the world, still fails to provide evidence-based preventive services and therapies that have been shown to decrease morbidity and mortality in almost half of all patient visits. At the same time that quality deficiencies are being noted, the cost of providing health care in the United ...
