1. Differentiators based on operational amplifiers do not suffer from drift.

2. An N-order tracking differentiator is put forward, then its convergence is proved.

3. The jam fault of the differentiator is dangerous to steam turbine.

4. By using differentiator series method, the formula of partial integration is obtained.

5. In this paper, introduced the Differentiator Series Method to solve the five - dimensional wave equation problem.

6. Convolutional differentiator (CD) is obtained by inverse Fourier transform of bandlimited Fourier spectra of partial derivative operator. CD is symmetric or antisymmetric and decays rapidly.

7. It consists of a synchronizing input circuit, delayed unit, generator of triangular wave and a differentiator.

8. The latest announcement suggests that security has entered the fray as a new differentiator.

9. This remains a huge opportunity for Apple and, in our view, is a major differentiator for the company. Apple has been able to successfully monetize China where competitors have been challenged.

10. In the near future an RIA pro will be a key resume differentiator.

11. Taking Napster as the first popular example of peer-to-peer computing,(sentence dictionary) the key differentiator was the fact that the nodes in the grid (the users) could exchange data (music) directly with one another.

12. Using forward inverse Fourier transform, we present hybrid order convolutional differentiator algorithm for seismic wave modeling.

13. To enhance the anti - interference capability of the control system, a nonlinear tracking - differentiator is employed.
