UMHexagonS is one of the fast motion estimation algorithm adopted by H.264/AVC. It saves about 90% computational work compared with the Full Search Algorithm, and still keeps a good rate-distortion quality. In this paper, the characteristics of UMHexagonS were firstly analyzed, and three aspects of improvements, which include zero-motion block pre-determination after starting point prediction; improvement...
Tensile creep of Ni 80 P 20 and Fe 78 B 13 Si 9 alloys with grain sizes of 27-28 nm has been studied at temperatures around 0.5 T m (T m is the respective melting point). The strain-time relation in the primary creep is found to obey the Andrade's law. The stress exponents and activation energies measured in the steady state...
