Discovering patterns from large datasets is inevitable in the modern data driven civilization. Many research works, and business models are depending on this excavation task. An efficient method for identifying categorizing different an exponentially growing database required to perform a clear excavation. A set of fresh processes such as Repeat Pattern Finder, Table, Threshold Analyzer, Node c...

In the design of shield tunnels, it is important to determine structure diaphragm wall in order achieve required retaining pattern. this paper, stabilization effect a new (Π-formed wall) investigated based on model experiments and numerical simulations. By varying length wing its angle end wall, possible discuss different styles Π-formed support soil behind during departure reception machine, i...

Archaeological excavation documentation poses several challenges to spatial data management. This work gives a data model, respective query functionality and the description of the resulting prototype system for recording and analyzing the data produced during the course of an excavation. Based on a requirements analysis, we develop a data model that not only captures georeferenced finds (potte...

This paper discusses the development of excavation techniques in England and their application to historical archaeology in Australia. Edward Higginbotham, a consultant archaeologist in Sydney, applies his experience of excavations in both countries to a critical analysis of various excavation methods, including test-pits, trial-trenches, the grid method, and area excavation. The advantages, ef...

Xiaowan Hydropower station’s dam located in south west of China is the second highest arch dam in the world (h = 292 m), its foundation is based on brittle rocks of biotite granite gneiss and amphibolites plagioclase gneiss. A largescale excavation around the foundation of the dam was conducted, near to 90 meters horizontal depth excavation and 130 meters vertical depth excavation, so the found...

Glaucoma is one of the most insidious eye diseases the occurrence and progression of which a human does not feel. This article provides a brief overview of the eye nerve parameterization methods and algorithms. Parameterization itself is an important task that provides and uniquely defines the structure of the optic nerve disc and further can be used in disease detection or other studies that r...

Evaluation of the excavation-induced ground movements is an important design aspect of supporting system in urban areas. This evaluation process is more critical to the old buildings or sensitive structures which exist in the excavation-affected zone. Frame distortion and crack generation are predictor, of building damage resulted from excavation-induced ground movements, which pose challenges ...

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.

Abstract—In order to prevent encountering unpredictable factors, geotechnical engineers always conduct numerical analysis for braced excavation design. Simulation work in advance can predict the response of subsequent excavation and thus will be designed to increase the security coefficient of construction. The parameters that are considered include geological conditions, soil properties, soil ...

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...
