In Iraq, the increase in earthquake activity was observed, but most of existing buildings can still suffer from severe injury or destruction, and therefore cause major issues. this paper, we performed numerically analyses by experimental modeling to demonstrate efficiency using final element analysis (FEA) development modern solutions maintain structures risk earthquakes. Using ABAQUS software ...

We analyze optical phased arrays with aperiodic pitch and element-to-element spacing greater than one wavelength at channel counts exceeding hundreds of elements. We optimize the spacing between waveguides for highest side-mode suppression providing grating lobe free steering in full visible space while preserving the narrow beamwidth. Optimum waveguide placement strategies are derived and desi...

Humanity already possesses the fundamental scientific, technical, and industrial know-how to solve the carbon and climate problem for the next half-century. A portfolio of technologies now exists to meet the world's energy needs over the next 50 years and limit atmospheric CO2 to a trajectory that avoids a doubling of the preindustrial concentration. Every element in this portfolio has passed b...

This algorithm is appropriately named linear search and has worst-case O(N) time complexity where N is the length of the input array corresponding to checking every element in the array. While linear search takes advantage of the sequential nature of an array (and in general, any sequential data structure), it does not take full advantage of this property. In particular, if the array is ordered...
