Seawater hydraulics: From the sea surface to depths of 11000 meters

Using seawater as the working medium,the seawater hydraulic system has significant advantages in the deep sea,such as eliminating contamination caused by oil leaks,no oil tanks,and the ability to automatically adapt to sea depths.As working depths increase,seawater hydraulic technology faces enormous challenges.First,the physical and chemical properties of seawater,such as density,temperature,and composition,change significantly.Second,hydraulic components are subject to an environmental pressur...     

Power Minimization of FPRM Functions Based on Polarity Conversion

For an n-variable Boolean function,there are 2^n fixed polarity Reed -Muler(FPRM)forms.In this paper,a frame of power dissipation estimation for FPRM functions is presented and the polarity conversion is introduced to minimize the power for FPRM functions.Based on searching the best polarity for low power dissipation,an optimal algorithm is proposed and implemented in C.The algorithm is tested on seven single output functions from MCNC benchmark circuits.The experimenta results are shown in this paper.
