Non-Contact And Non-Invasive Method For Measurement Of Head Posture In Neurology

Patrik Kutilek and Jiří Hozman

Abstract


Head posture can be influenced negatively by many diseases of the nervous system, visual and vestibular systems. This article explains our method of non-invasive and non-contact head position measurement by only two cameras mounted opposite each other. By this way we could avoid an influence on patients during the time of measurement of the inclination (roll), flexion (pitch) and rotation (yaw) of the head. This is very important advantage for medical doctors because they can apply various examinations which need open space in front of a face.

Keywords


head posture, neurology, inclination, rotation, flexion, fuzzy logic

Radar Interception Area Analysis

Štefan ŠPIRKO, Zdeněk MATOUŠEK

Abstract


The paper deals with the method proposed for radar interception area analysis, which can be utilized in routine applications. Paper presents formulas derivation for the evaluation of estimated parameters of targets located within radar interception area, which is utilizable for practical radar comparison. Proposed method is demonstrated with example of two particular made-up radar data.

Keywords


Radar cross section, false alarm probability, interception probability, radar interception area, target detection range.
