Since the implementation of the new mechanism of renminbi exchange rates in 2005, their fluctuation range has become more greater. Therefore, it is very important to control renminbi exchange rates risk via forecasting. This paper describes four alternative renminbi exchange rates forecasting models. These models are based on autocorrelation shell representation and neural networks techniques. An...
Recent advances in sensor technology are facilitating the deployment of sensor networks into the environment that can produce measurements at high spatial and/or temporal resolutions. Through telemetry, these measurements can be delivered in near real time as data streams for use in real-time applications. These data streams can be instrumental in furthering our understanding of the environment, in...
Ontology theory is a scientific methodology which standardizes the description of knowledge and concept by computer language, organizes knowledge, and does knowledge service. Knowledge management is official management for knowledge in order to make it convenient to produce, access and re-use knowledge. The key ontology technologies applied in the knowledge management field are studied in the paper...
Pop-up threats usually appear or disappear randomly in a battle field. If the next pop-up threat locations could be predicted it would assist a search or attack team, such as in a persistent area denial (PAD) mission, in getting a team of unmanned air vehicles (UAVs) to the threats sooner. We present a Markov model for predicting pop-up ground threats in military operations. We first introduce a general...
