Microwave measurements Part I: Linear Measurements

Rapid estimation of sunflower leaf area from linear measurements

Accuracy and precision of measurements obtained from conventional cephalograms and CBCT scan in orthodontics linear diagnostic measurements

Background and Purpose:  Due to the important role of imaging in the diagnosis and treatment plan in orthodontics, CBCT (Cone Beam Computed Tomography) images because of their three-dimensional nature, can minimize the disadvantages of two-dimensional images such as magnification, distortion, or superimposition. The purpose of this study was to evaluate the accuracy of conventional cephalograms...

Modelling Microwave Measurements in Wood

It is possible to determine properties of wood using microwave scanning techniques. The purpose of this study was to verify the measured values from a microwave imaging sensor. Attenuation and phase shift of an electromagnetic wave transmitted through birch wood were measured and compared with theoretical calculated values. A test piece with varying thickness was measured with a scanner based o...

Ground-Based Microwave Radiometer Measurements

This particular site and time of year was chosen by ARM because it offers a high probability of clearsky, and also a wide range of integrated water vapor amounts. To supplement the routine observing capabilities during the WVIOP2000, a powerful array of tools for measuring water vapor was deployed at the SGP Central Facility area. A comprehensive suite of airborne in situ and ground-based remote

accuracy of linear measurements using cone beam computed tomography in comparison with clinical measurements

objectives: this study sought to evaluate the accuracy and errors of linear measurements of mesiodistal dimensions of kennedy class iii edentulous space using cone beam computed tomography (cbct) in comparison with clinical measurements. materials and methods: nineteen kennedy class iii dental arches were evaluated. an impression was made of each dental arch and poured with dental stone. the di...
