Background: Pulmonary nodular excavation should firstly evoke tuberculosis or necrosis broncho-pulmonary tumor, particularly: epidermoid carcinoma. The case discussed here illustrated these difficulties in patients with rheumatoid arthritis (RA). Case Presentation: A 63-year-old woman was presented with a-three-year history of RA and a recent discovery of an excavated pulmonary nodule. Initi...

The Beaver Creek Trail Crossing Site was a fording location along the Nebraska City Cut-Off of the Oregon and California Trail, occupiedfrom 1862 through 1871. The site was situated on both creek banks and contained a road ranch. saloon, store, and post office. Geophysical data showed anomalies corresponding to irregularities in the ground surface. While excavation units placed at these locatio...

Motion measurements obtained from a maneuvering 1/16-scale dragline excavation system using a six camera motion capture system are compared against motion predictions of the same scenario using a complex dragline excavation system simulation. The dynamic model includes motion of the bucket, spreader bar, hoist cluster, and drag cluster, along with flexible rope and chain segments including the ...

With the large-scale construction and rapid development of underground engineering, a large number of underground engineering construction, such as tunnel and subway emerged. The geological structure of the tunnel is complex and the roc is fragmented. Tunnel seismic image is a new geophysical technique. This method has advantages such as high resolution, high reliability and obvious image chara...

We are developing a collaborative system for offsite visualization of an archaeological dig site through both virtual and augmented reality. Multiple users, wearing tracked, head-worn, see-through displays, can interact with the environment using tracked, instrumented gloves, a multi-user, multi-touch, projected table surface, large wall displays and tracked hand-held displays. We take advantag...

As the Semantic Web gains momentum, so grows the interest in making knowledge kept in various repositories available. In this paper we describe a case study using a methodological approach for porting cultural repositories to the Semantic Web. The approach consists of thesaurus conversion, meta-data schema mapping, meta-data value mapping, and thesauri alignment. It is derived from our experien...

Information concerning the size and shape of tunnel boring machine (TBM) debris is essential for designing efficient loading, hauling and dumping systems for TBM excavation. It is also very important in deciding how to recycle the TBM debris. However, only very limited information is available at present, and theoretical or calculation methods to estimate the size and shape are still open to di...

PURPOSE To study the prevalence, tomographic features, and clinical characteristics of focal choroidal excavation (FCE) in eyes with exudative age-related macular degeneration (AMD). METHODS We examined 243 consecutive eyes with exudative AMD with a prototype swept-source optical coherence tomography (OCT) system. Three-dimensional images of the macular area, covering 6 × 6 mm(2), were recons...

In this paper, an innovative instrument for the measurement of the soil displacement, developed at the laboratories of the Departments of Civil and Information Engineering of the University of Parma and currently under patenting, is presented. The instrument, which can be used in any application requiring soil movement measurements, has been originally designed for the measurement of the axial ...
