AIM: This study aimed to assess the effect of changing the field of view on the dimensional accuracy of CBCT imaging.METHODS: The implant-bone models were randomly numbered from 1 to 13 by the principal researcher, and then on each model at the incisors r... see more

This paper describes measurements of the moisture field of Charles Bridge in Prague. The measurements were scheduled to cover a one-year cycle, including the spring, summer, autumn and winter, in order to monitor the behaviour of the bridge structure over... see more

This paper deals with assesing of the influence of climate temperatures on deformations and stresses in a cross section of the Nusle Bridge. The main purpose is to describe the measurement of the thermal fields, to compare measured and computed temperatur... see more

Ground-based measurements were carried out during field campaigns in April–June of 2010, 2011 and 2012 over northwestern China at Minqin, the Semi-Arid Climate and Environment Observatory of Lanzhou University (SACOL) and Dunhuang. In this study, th... see more

A miniaturised gigahertz transverse electromagnetic (GTEM) cell is designed and fabricated to generate uniform electric (E-) field, essential for studying the radio frequency exposure effect on tissue equivalent liquids at global system for mobile (GSM) c... see more

The radiation of RFID anti-theft gate system based on two parallel coaxial square loop antennas has been analyzed.The system was simulated in FEKO and near electric andmagnetic fields have been calculated. A physical model of thesystem was realized and ne... see more

This paper is dealing with measurement of a near-field strength in the region around a source, which is supply of radiation. Electromagnetic field is distributed inhomogeneously in this case. The field consists of two components field, vectors of electric... see more

A mathematical model describing distribution of an electromagnetic field around a rail with account of skineffect in rail steel is developed and experimental measurements of a magnetic intensity are carried out.

The work proposes a method allowing to check whether the desired accuracy of magnetic flux-density vector’s measurement can be achieved using a magnetic 3D probe based on three sensors with output characteristics dependent on all the magnetic-flux de... see more
