The secrecy capacity of a discrete memoryless Gaussian Wire-Tap Channel when the input is from a finite complex constellation is studied. It is shown that the secrecy capacity curves of a finite constellation plotted against the SNR, for a fixed noise variance of the eavesdropper’s channel has a global maximum at an internal point. This is in contrast to what is known in the case of Gaussian co...

Ultimate bearing capacity calculation is one of the most important factor to design foundations in geotechnical engineering. In this paper, ultimate values were calculated with finite element and analytical methods compared. A case study Bozozuk (1972) article used for evaluations. On 30 September 1970, 600-ton weight concrete silo suddenly overturned failure. After failure, in-situ Vane shear ...

soil slopes are sometimes curved in plan rather than being straight. this curvature,especially when it is convex, decreases the bearing capacity of the slope. finite element methodhas been used here in this research to investigate the reducing effect of curvature on bearingcapacity of a slope. failure of soil has been assumed to be according to mohr-coulomb criteria;but the flow rule of the soi...
