A distributed localization scheme based on mobility prediction for mobile underwater wireless sensor networks is proposed. Anchor nodes perform self-localization and mobility prediction, and serve as reference nodes to localize ordinary nodes. According to the group movement properties of underwater objects, ordinary nodes perform self-localization by utilizing the neighboring nodes' locations and...
In the electricity market, the price as the lever results in the dramatic variations, especially, the capacity or willingness of electricity consumers and then demand may be low, particularly over short time frames. Therefore demand-side management (DSM) has been put into practice, and the market supervisors become more and more focused on the price dynamics of the short-term, because of its effects...
Accurate and frequent measurements of quality variables are important for real-time process monitoring and control. However, because online measuring instruments commonly have the limitations of high investment and low accuracy, while offline laboratory analyses are obtained manually and infrequently, neither online instruments nor offline analyses can satisfy the requirements of real-time applications...
There are some small-sample cases in economic forecast, for lacking of quantitative information, in which it happens that some given forecasting method fits well while behaves badly in forecasting, while to the contrary, the situation behaves well when we make the combination of both qualitative and quantitative methods in forecasting. The concept of risk of forecasting is defined, as well as the...
The similar growth mechanism of equipment scale and single species scale was analyzed. Then, take the equipment expenditure scale as monetary measurement of equipment scale, the basic growth model of equipment expenditure scale was established on the base of Multhus model of single species growth. Next, take the equipment expenditure scale growth ratio as linear minus function, the basic model was...
