Creating a dental model from a series of images of an intra-oral object includes the steps of (a) capturing a series of images of an intra-oral object from a plurality of capture positions, where the object includes common surface features and a control target arranged with respect to the object to provide control features; (b) measuring the common features from the series of images of the object and the control features from the control target imaged with the images of the object; (c) analytically generating a 3-dimensional model of the object by photogrammetrically aligning the measurements of the control features, thereby reducing image errors due to the variability of the capture positions; and (d) adjusting the photogrammetrically aligned 3-dimensional model of the object by aligning the common features of the model to like features on the image of the object, thereby producing an aligned dental model from the series of images.

In a circuit switched mobile telecommunications network a performance analysis is provided. In accordance with the invention a method is implemented, which can be carried out both OFF-LINE and ON-LINE, wherein transport channels carrying the circuit switched traffic of a service are found, then bit-streams of the circuit switched traffic are demultiplexed. A traffic database is built and a set of Key Performance Indicators and usage measures characterizing the service are defined and calculated. A passive traffic monitor is also disclosed, which is attached to a standardized interface of the circuit switched mobile telecommunications network consisting of mobile terminals, radio access network and core network. The passive traffic monitor comprises a trace analyzer connected to a signaling analyzer, to a user plane protocol analyzer and to a traffic database writer. The traffic database writer generating a traffic database is linked to the signaling analyzer, to the trace analyzer and to the user plane analyzer.

This invention relates to a device and method for optical nanoindentation measurement, according to which respective measurement results are obtained by having an indenter tip apply load to a fixed portion of a thin film, having an indenter tip apply load to a non-fixed portion of a thin film, and having a vibrating component transmit the dynamic properties of the vibration to the thin film. By combining the above measurement results in calculations, the Young's modulus, the Poisson's ratio, and the density of the thin film can be obtained.

An electron beam observation device includes a mechanism which disposes a specimen at an upstream side in an electron beam traveling direction outside an objective lens, from which an image is transferred under a magnification of ⅕ to 1 / 30, in addition to an inside of the objective lens in which a specimen is disposed at a time of ordinary observation.
