With the development and wide application of the computing technology, performance testing becomes more and more important. Real simulation of the user behavior becomes a concern of the performance testing. The paper introduces the potential model to establish the model of the visit amount which can be used in the performance testing. Firstly, the paper introduces the role of HBase in the search engine...
The development and wide application of the internet technology produces a large amount of data, in order to storage and manage these massive data, NoSQL database technology comes into beings and develops rapidly, many manufacturers have introduced many different NoSQL storage solutions. In this context, the paper carries out the work about the testing method of the performance of NoSQL database....
In this paper, flexible MEMS inductors based on Parylene-FeNi Compound Substrate (PFCS) were designed, fabricated and analyzed. We choose parylene as substrate to achieve flexibility and good bio-compatibility. Then, a Ni80Fe20 magnetic film was deposited on the parylene film to form a compound substrate. Moreover, a Ni80Fe20 core was also deposited in the center of the spiral inductor to improve...
An electromagnetic acoustic transducer (EMAT) can emit and receive ultrasonic waves though electromagnetic coupling. The non-contact characteristic of EMAT makes no coupling medium, so it is specially concerned by researchers on nondestructive testing and evaluation. This paper mainly introduce the design of electrical parameters and geometric parameters of electromagnetic acoustic surface wave detection...
