This paper presents an experimental and numerical analysis of the uplift resistance pipelines buried in reinforced soil. The behavior system is studied using a set laboratory experiments. pull-out forces some reinforcing are most important factors affecting resistance. Buried elements such as that have high pressure fluids or under temperature need to be order increase their One efficient metho...

Through the theoretical analysis of overburden destabilization mechanism, FLAC 3D simplified plane numerical simulation method and field measurement method, we compared relationship support pressure at 35 m workface recovery, peak decreased from 13.85 Mpa to 11.97 1:1 1:3. With increase mining ratio, over-supporting decreases: with top coal recovery thickness, influence range will be further ex...

We present a method for detecting anomalies in vibration signals of wind turbine components. The predominant characteristics of wind turbine vibration signals are extracted by applying a time-frequency feature extraction method based on Fourier local autocorrelation (FLAC) features. For anomaly detection, one-class classification based on an unsupervised clustering approach is applied in consid...

introduction: three-dimensional (3d) scanners are widely used in medicine. one of the applications of 3d scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. the aim of this study was to evaluate the precision and accuracy of a modified 3d scanner fabricated in this study. methods: in this work, a 3d scan of the human body was o...

In order to verify the applicability of computer numerical simulation method under complex engineering conditions, and solve problem that it is difficult guarantee normal construction underground projects with a depth more than 1 km (it carry out multiple field attempts high-depth if you simply use ordinary calculation method, its accuracy guarantee). For geological conditions an mine 1300 m in...

INTRODUCTION The use of Top Coal Caving for exploiting the thick coal seam with shallow buried depth most likely has a strong negative impact on the stability. CASE DESCRIPTION Anjialing No. 1 Underground Mine is located in Shuozhou City, Shanxi Province of China. The 4# Coal Seam of this coal mine is the thick coal seam with shallow buried depth, which has the thickness of 12 m and the depth...

A series of 102 transfer-deficient (tra(-)) mutants of Flac (84 of which have been previously described) were classified as carrying frameshift, amber, ochre, UGA, and nonsuppressible mutations. Techniques were evolved for using cultures of F prime strains as efficient recipients in matings, for measuring the number of (F'/F') heterozygote cells in transient populations, and for measuring compl...

The replication region fragments from Flac(+) cloned in plasmids pSC138 and pML31 are identical with each other and with EcoRI fragment 5 of plasmid F.
