This paper describes the further development of virtual flow meter concept based on author’s simulator an unsteady gas–liquid in wells. The results comparison with commercial simulators real well data are given as practical applications. demonstrated high correspondence (<10% error) for a number target parameters. description architecture and testing algorithm automatic settings model parame...

Training on measurements to determine the characteristics of the three-phase electrical system is very useful for a deep knowledge of the theoretical aspects. Laboratory sessions for measurement by using advanced technologies must be performed. Two implemented tools are presented. The first one fulfils some requirements: it uses a virtual instrument, will be used in distance learning sections a...

iran’s industry has had a considerable number of difficulties to perform so well as was expected in the post – revolutionary era. unfavorable legal, political environments combined with eight –year imposed war may be singled out as the root causes of such performances. however, this paper argues that our industry’s lack of realization of its dire need to adapt to the emerging unprecedented envi...

Weight function distributions for an electromagnetic flow meter with a non-insulating pipe are numerically simulated and verified. The weight function distribution is very important for solution of flow velocity of distribution. In this paper, a finite element method (FEM) is used for solving the weight function distribution for this novel electromagnetic flow meter. First of all, a numerical s...

Automated 3D modeling of building interiors is useful in applications such as virtual reality and entertainment. Using a human-operated backpack system equipped with 2D laser scanners and inertial measurement units, we develop four scan-matching-based algorithms to localize the backpack and compare their performance and tradeoffs. We present results for two datasets of a 30-meter-long indoor ha...

We propose and experimentally demonstrate a new method to extend the range of Brillouin optical time domain analysis (BOTDA) systems. It exploits the virtual transparency created by second-order Raman pumping in optical fibers. The idea is theoretically analyzed and experimentally demonstrated in a 50 km fiber. By working close to transparency, we also show that the measurement length of the BO...

We present a method for measurement of human tissue compliance in vivo using a commercial haptic interface to apply known step changes in force while recording the resulting displacements. We introduce our system, the Softcometer (SOFT-tissue COmpliance METER). Our motivation was to improve the compliance realism of our Virtual Haptic Back model, but there are many potential applications for th...
