Aimed to provide basis for continuous and steady growth in grain output of He'nan, the empirical mode decomposition method and variance decomposition method are comprehensively applied in the paper, and the fluctuation characteristics of grain output in He'nan from 1985 to 2013 are systematically analyzed at different scales. It is indicated from results that: ①at the provincial scale, change in grain...
Development of inland water transport management is the major macroeconomic research of the transport. Using grey theory method, GM (1,1) management parallel calculation model is established. The model analysis the growth rate of highway, waterway and railway, forecasts the trend of the carrying capacity of water transportation, inland waterways mileage and high-grade waterways mileage in China.
Solid-state drives (SSDs) have a growing trend of replacing hard disk drives (HDDs) in large computing systems to meet the requirements of power and space. Data in SSD are stored in NAND flash memory cells. Since 2-dimensional (2D) scaling is facing various limitations, 3D-NAND flash memory architectures have been proposed to maintain the trend of bit density increase and bit cost reduction, which...
The required storage class memory (SCM) capacity and NAND over-provisioning (OP) for SCM/NAND hybrid enterprise solid state drive (SSD) are evaluated for various storage workloads. From the worst case simulations (hot and random data intensive workloads), it is found that less than 8% SCM/NAND capacity ratio with below 25% NAND OP is sufficient assuming SCM bit cost is 10-times as high as that of...
Measurement of transmission lines galloping amplitude is the very important part of wire monitoring. Aimed at reducing errors of the method, this paper presents a improved method which applies acceleration transducer for getting the precise values of galloping amplitude. This paper states the fundamental of the way using acceleration transducer to measure wires' galloping acceleration and then bring...
