Metamaterials are artificial multifunctional materials that acquire their material properties from their structure, rather than inheriting them directly from bald ass dog the materials they are composed of, and they may provide novel tools to significantly enhance the sensitivity and resolution of sensors.In this paper, we derive the dispersion rel
A method for measuring the thermal diffusivity of solid materials under combined boundary conditions in combination with the idea of inverse heat transfer problem is proposed.Based on the idea of the h?rklype finite volume method and the alternating direction implicit method, MATLAB software is used to numerically solve the temperature field of the
Typhoons often cause huge losses, so it is significant to accurately predict typhoon fender two tone amp tracks.Nowadays, researchers predict typhoon tracks with the single step, while the correlation of adjacent moments data is small in long-term prediction, due to the large step of time.Moreover, recursive multi-step prediction results in the acc
The recent seismic code SNI 1726-2012 is significantly different compared to the older code SNI 1726-2002.The seismic hazard map was significantly changed and the level of maximum considered earthquake was significantly increased.Therefore, buildings designed according to outdated code may not resist the higher demand required by newer code.In this
