Three-Dimensional Imaging for a Very Large Excavator
نویسندگان
چکیده
In this paper we describe the development of a three-dimensional (3D) imaging system for a 3500 tonne mining machine (dragline). Draglines are large walking cranes used for removing the dirt that covers a coal seam. Our group has been developing a dragline swing automation system since 1994. The system so far has been “blind” to its external environment. The work presented in this paper attempts to give the dragline an ability to sense its surroundings. A 3D digital terrain map (DTM) is created from data obtained from a twodimensional laser scanner while the dragline swings. Experimental data from an operational dragline are presented. KEY WORDS—mining, dragline, terrain map, lasers, automation

Three-Dimensional Image of A Communicating Uterus
Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).
متن کاملEvaluation of a fast method of EPID-based dosimetry for IMRT and Comparison with 3D EPID-based dosimetry system using conventional two- and three-dimensional detectors for VMAT
Introduction: Electronic portal imaging devices (EPIDs) could potentially be useful for intensity-modulated radiation therapy (IMRT) and VMAT QA. The data density, high resolution, large active area, and efficiency of the MV EPID make it an attractive option. However, EPIDs were designed as imaging devices, not dosimeters, and as a result they do not inherently measure dose in ...

Analysis of Planar Microstrip Circuits Using Three-Dimensional Transmission Line Matrix Method
The frequency-dependent characteristics of microstrip planar circuits have been previously analyzed using several full-wave approaches. All those methods directly give characteristic of the circuits frequency by frequency. Computation time becomes important if these planar circuits have to be studied over a very large bandwidth. The transmission line matrix (TLM) method presented in this paper ...

Human hydatid cyst is a wide spread disease. It is an endemic disease in Iran. Hydatid cyst is extremely rare in the female reproductive organs. This is a case report of ovarian hydatid cyst in a 42-year-old woman. She presented with feeling of enlargement of abdomen and abdominal pain. On physical examination, a large mass in lower abdomen palpated. Ultrasonography reported a heterogeneous ...
