Because the signal of water pump bearing is seriously disturbed by noise and the fault evolution is complex, it is difficult to describe the performance degradation trend of water pump bearing in a timely and accurate manner using the traditional performance degradation index (PDI).In this paper, a new Cluster Migration Distance (CMD) algorithm is
In the paper titled as "Jackson-type inequality on the sphere" (2004), Ditzian introduced a spherical nonconvolution operator , which played an important role in the proof of the well-known Jackson inequality for spherical harmonics.In Tiffany Table Lamp this paper, we give the lower bound of approximation by this operator.Namely, we prove that the
The art of designing clothing fabrics is a multidisciplinary design important and difficult because Tiffany Table Lamp it is linked to man and his personality and his tastes and habits and behavior being is a form of creative expression here came the problem of the research , which are summarized by asking the following: Is the similar role in the
Vocal production learning and beat perception and synchronization (BPS) share some common characteristics, which makes the vocal learning and rhythmic synchronization hypothesis (VLH) a reasonable explanation for the evolution of the capability for rhythmic synchronization.However, even in vocal learners, it is rare to see non-human animals demonst
