In order to model real behavior of jackup platforms subjected to environmental conditions, a nonlinear dynamic analysis considering soil-structure interaction subject to wave loading is investigated. For this purpose, spudcans behavior, soil nolinear behavior near the structure, contact phenomena at the interface of the soil and foundation such as gapping as well as geometrical nonlinear behavi...

Climate change caused the changes in earth surface temperature, precipitation, sea surface level, wind speeds, wave heights, coastlines, etc. Estimation of the effect of climate change is of great importance in long-term studies of such parameters. In this study, the effect of climate change on average wind speed near Chabahar, Gulf of Oman is assessed until the year 2100. For this purpose, win...

In the present paper a novel structure for optical channel drop filter (CDF) based on photonic crystal ring resonator with circular core has been proposed. In order to design the proposed CDF, the plan wave expansion (PWE) method is applied for calculation of band structure and photonic band gap while the transmission characteristics of proposed CDF have been calculated using the finite differe...

W reflection seismology, surface waves or ground roll, are often considered a form of unwanted sourcegenerated noise. Unlike body waves, surface waves propagate exclusively in the lateral direction and are virtually insensitive to structure deeper than one wavelength. For a nominal frequency of 5 Hz and phase velocity of 500 m/s, this means that a surface wave of the Rayleigh or Love type only ...

burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...

near-surface variations can be very complex and may distort amplitudes and arrival times of the reflections events from target reflectors. near-surface complexities include topographic variations, near-surface irregularities, variations in soil conditions and the weathered layer. these perturbations generally have a significant impact on seismic recordings. although there is a general agreement...
