To study the effects of spudcan penetration on the adjacent foundations of offshore platforms, experiments and numerical simulations (using business software ABAQUS) are carried out. It is shown that the penetration of spudcan can cause the soil layer affected in an annular zone. The affected zone has a maximum width of one times the diameter of the spudcan. The deflection of the platform’s fou...

This paper presents a modified form of the Walker-Anderson (W-A) model for analyzing high velocity penetration of an eroding projectile into a concrete target in which the W-A model is improved by incorporating calculations for the plastic flow field of concrete in terms of its compressibility and strain rate sensitivity under severe pressure. With the changes to and calculations of plastic fie...

The kagome lattice consisting of corner-sharing triangles has been studied in the context quantum physics for more than seventy years. For novel discovered superconductor CsV3Sb5, identifying pairing symmetry order parameter remained an elusive problem until now. Based on two-band Ginzburg–Landau theory, we study temperature dependence upper critical field and magnetic penetration depth this co...

A theoretical method for extracting diffractograms from a range of depths will be described. The method is non-destructive and requires only a series of traditional data collections, where the incident angle is varied. The measured spectra are transformed to give calculated X-ray diffraction data arising from different depths. This is in contrast to conventional approaches where either a specif...

We present experimental measurements of penetration depths for the impact of spheres into wetted granular media. We observe that the penetration depth in the liquid saturated case scales with projectile density, size, and drop height in a fashion consistent with the scaling observed in the dry case, but with smaller penetrations. Neither viscous drag nor density effects can explain the enhancem...

simultaneous heat and water model (shaw) is based on the assimilation rate of melting and/or freezing of the accumulated snow as well as melting of ice in soil. the main objective of this study was to evaluate applicability of shaw model in determining maximum depth of frost penetration in soils in some typical climates of iran. to this end, the daily data of air temperature, soil temperatures ...

We report a comprehensive study of the ${\mathrm{Zr}}_{5}{\mathrm{Pt}}_{3}{\mathrm{C}}_{x}$ superconductors, with interstitial carbon between 0 and 0.3. At macroscopic level, their superconductivity, ${T}_{c}$ ranging from 4.5 to 6.3 K, was investigated via electrical-resistivity, magnetic-susceptibility, specific-heat measurements. The upper critical fields ${\ensuremath{\mu}}_{0}{H}_{\mathrm{...

The optical properties of single crystals of the high-temperature superconductor La2−xBaxCuO4 have been measured over a wide frequency and temperature range for light polarized in the a-b planes and along the c axis. Three different Ba concentrations have been examined, x = 0.095 with a critical temperature Tc = 32 K, x = 0.125 where the superconductivity is dramatically weakened withTc 2.4 K, ...

Recently, advances in film synthesis methods have enabled a study of extremely overdoped $La_{2-x}Sr_{x}CuO_{4}$. This has revealed surprising behavior the superfluid density as function doping and temperature, explanation which is vividly debated. One popular class models posits electronic phase separation, where superconducting fraction decreases with doping, while some competing (e.g. ferrom...
