If you’re unsure how to find the area of a space, try using oursquare footage calculator. For example, let’s find how many linear feet of hardwood flooring will be needed to cover a 120 sq. ft. room if the boards are 3″ wide. ...

Drilling was done through approximately 4500 ft of active shale and depleted sands and was complete in about 6 days with an average drilling rate of 32 ft/hr. (For comparison it was estimated that it would have taken 18 days for drilling with a water-based mud). There were no sticking ...

类型Kernel::FT必须满足CGAL中FieldNumberType概念,这大致意味着Kernel::FT是一种定义了+,−,∗和/的类型,其数学语义(大致)与所关联的field的相关运算相同。需要注意的是:内置类型int不满足field类型的要求,因为int对应的是环(ring)而非域(field),特别/运算不是*运算的逆。Kernel::RT的类型要求则相对较弱,...

After the quadrature down conversion of r(t), the lowpass filters (LPFs) are added to remove the high-frequency components, and ADCs are used for the signal sampling. The time delays of I and Q branches are denoted as δI and δQ, respectively. In addition, due to the difference of ...
Introduction The advantages of linear actuators over rotation-to-translation conversion systems when linear motion is needed are well documented in the literature [1]. Applications of linear actuators are mainly in industry and transportation due to its force density, efficiency, levels of acceleration,...
