Partition piles are widely used in tunnel displacement control under excavation. However, the effect of partition has not been systematically studied, and centrifuge model test is lacking. In view this situation, design deformation adjacent existing caused by excavation terms dry sand foundation was carried out, a series optimization designs were out experimental process according to numerical ...

Stability of the vertical excavation had been examined using finite element method for a different depth of excavation while structural static and dynamic load with worst possible moment criteria .The critical depth had been examined based on finite element method value of two dimensional interface stresses, ignoring the third dimension stresses, were verified experimentally for an exact analys...

The objective of this study is to design a robust direct model reference adaptive controller (DMRAC) for a nonlinear cardiovascular model over a range of plant parameters representing a variety of physical conditions. The direct adaptive controllers used in thisd study require the plant to be almost strictly positive real (ASPR) that is, for a plant to be controlled there must exist a feedback ...

I F we consider that agriculture employed a majority of the population in non-industrial societies and is still man's staple occupation, we must ad-mit that the agriculture of Roman Britain has concerned archaeologists and historians much less than it should, for on its vicissitudes depended to no small degree the well-being and decline of the province. The existence of Roman 'villas' was first...

PURPOSE To report the clinical findings of 2 patients with focal choroidal excavation in the macula detected by spectral-domain optical coherence tomography (SD-OCT). METHODS Three eyes of 2 patients with a focal macular choroidal excavation detected by SD-OCT were studied. The eyes were examined by fundus autofluorescence (FAF), fluorescein angiography, fundus-related microperimetry, and mul...

Seismic pounding occurs as a result of lateral vibration and insufficient separation distance between two adjacent structures during earthquake excitation. This research aims to evaluate the stochastic behavior of adjacent structures with equal heights under earthquake-induced pounding. For this purpose, many stochastic analyses through comprehensive numerical simulations are carried out. About...

Focal choroidal excavation is a choroidal pit that can be detected by optical coherence tomography. Central serous chorioretinopathy, choroidal neovascularization and polypoidal choroidal vasculopathy are pathologies associated with focal choroidal excavation. In this article, we present the follow-up and treatment outcomes of three eyes of two patients with focal choroidal excavation.

The cartographic generalization prepares and arranges the contents of a map for a given scale and application in order to improve its comprehensibility. In recent years, the data sets for map-like presentations in 3D has become widespread available. Concerning urban areas, the most important objects therein are buildings. Whereas quiet a number of generalization algorithms for 3D data have been...

A new presupporting technology named freeze-sealing pipe roof (FSPR) method was adopted in the construction of Gongbei tunnel (Zhuhai, P.R. China), which a critical part Hong Kong-Zhuhai-Macau Bridge (HZMB). The combined pipe-roofing with artificial ground freezing (AGF). water resistance performance FSPR surrounded by water-rich soils studied based on field temperature data. time-dependent cha...
