One of the main distinctions between geomaterials and other engineering materials is the spatial variation of their properties in different directions. This characteristic of geomaterials -so called heterogeneity- is studied herewith. Several spatial distributions are introduced to describe probabilistic variation of geotechnical properties of soils. Among all, the absolute normal distribution ...

– We study the electrostatic effects on the undulation of a flexible membrane with non-vanishing excess charges and charge fluctuation. It is shown that the membrane becomes unstable to a long-wavelength undulation due to Coulomb repulsion between excess charges on the membrane. This instability is suppressed both by charge fluctuation which induces an effective attraction and by free ions in s...

In order to solve the problem of energy consumption, improve efficiency utilization and develop new energy, total consumption fluctuation thermal integrated were analyzed. Four suggestions are put forward for power system flexible plant, namely, electric heat storage system, pump g, heating high pressure via steam turbine, which can air capacity reduce coal system. Among them, in case small con...

purpose: to introduce a patient with best disease and fluctuation in vision and oct changes. case report: a 26-year-old man presented with decreased va in his left eye due to cnv secondary to best disease. va improved after ivb injection. after 3 years he complained of metamorphopsia in his right eye with a decrease in subretinal deposits which improved spontaneously. the same sequence of event...

Chromosome condensation is one of the most critical steps during cell division. However, the structure of condensed mitotic chromosomes is poorly understood. In this paper we describe a new approach based on elasticity measurements for studying the structure of in vitro assembled mitotic chromosomes in Xenopus egg extract. The approach is based on a unique combination of measurements of both lo...

Direct drive wave energy converters (DDWECs) have gradually become the mainstream of (WECs). In order to make better use energy, storage devices and other renewable sources are often used suppress power fluctuation in DDWECs. However, addition will increase complexity converter system number switches. Considering flexibility nine-switch (NSCs), this paper proposes a novel grid-connected/off-gri...

This study examines the impact of French Revolution on Convergence Ottoman-British politics in period from 1789 to 1815. where it reviews status both Ottoman Empire and state that period, showing nature development relations arose between two parties. The importance lies its attempt address political developments contributed fluctuation mutual Britain during period. aimed shed light role policy...

statistical studies on palynology contents of late cretaceous to paleocene age gurpi formation in a surface section in zagros basin,sw iran indicate changes in abundance, species diversity, ratio of spiniferites to cyclonephelium (s/c), palynological marine index(pmi) values and organic facies. these palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...
