When looking at an image, humans shift their attention towards interesting regions, making sequences of eye fixations. When describing an image, they also come up with simple sentences that highlight the key elements in the scene. What is the correlation between where people look and what they describe in an image? To investigate this problem, we look into eye fixations and image captions, two types...
Large-scale software systems like Amazon and healthcare.gov are used by thousands or millions of people every day. To ensure the quality of these systems, load testing is a required testing procedure in addition to the conventional functional testing techniques like unit and system integration testing. One of the important requirements of load testing is to create a field-like test environment. Unfortunately,...
In the paper, takes high college and university in Jiangxi province as an example, based on the survey in the targeted high college and university and systematic analysis on the high college and university actual situation, with the help of the literature review, research methodology and analytical framework of the competitiveness, the paper established the eight influencing factors that acted on...
The backbone of cloud computing platforms like Amazon S3 and Salesforce is formed by Ultra-Large-Scale (ULS) systems, i.e., complex, globally distributed infrastructure consisting of heterogeneous sets of software and hardware nodes. To ensure that a ULS system can scale to handle increasing service demand, it is important to understand the system's performance behaviour, for example to pro-actively...
According to the characteristic analysis of the LiFePO4 Li-ion battery, and aiming at the real-time identification of the model parameter, the battery model was established based on PNGV. The real-time identification of PNGV model parameter was achieved by fading memory delivery recursive least squares. The simulation results show that this method could identify the model parameters real-time more...
We studied empirically the relations among the CHIBOR, CPI, and PPI with a vector error correction model which is available through various kinds of statistics tests. There is at least a cointegration relation among CHIBOR, CPI, and PPI. Negative rate periods of actual CHIBOR are much more than positive rate periods' based on the cointegrating equation curve. Although the CPI and PPI affect the CHIBOR,...
