In practice, the data owners of source projects may need to share data without disclosing sensitive information. Therefore, privacy-preserving data-sharing becomes an important topic in cross-company defect prediction (CCDP). In this context, the challenge is how to achieve a high privacy-preserving level while ensuring the utility of the shared privatized data for CCDP. CLIFF&MORPH is a recently...
Distributed energy systems with solar photovoltaic (PV) power grow rapidly in recent years in China. Accurate power forecasting is important for deep utilization and new exploitation of PV power. This study advances power forecasting modelling of PV systems using a method based on similar day selection and M5' model trees. A one-day-ahead power output forecast model is derived for an experimental...
Extreme learning machine (ELM) is a fast online learning algorithm for single hidden layer feed-forward neural networks (SLFN), which keeps the fast learning speed with good performance. And it has been widely used on function approximation and prediction classification. However, the parameters in hidden layer of ELM are randomly determined which leads to the unstable prediction performance. So the...
Wall thickness has a direct impact on the appearance, performance and cost of a part, wall thickness analysis is important (sometimes essential) to examine and improve the manufacturability of a part after the design is complete. The current method of wall thickness analysis in pro/Engineering environment is to establish equally spaced cross-sections in different directions, which is inefficient and...
It presents an approach of moving target detection by multichannel synthetic aperture radar (SAR), which the receivers displaced in heterogeneous arrays. The approach achieves the maximal unaliased band of radial velocities and Minimum detectable velocity, retains full resolution SAR images, the multiple measurement vectors were employed for improvement of the target focusing, and requires no increase...
In-network content caching has recently emerged in the context of Information-Centric Networking (ICN), which allows content objects to be cached at the content router side. In this paper, we specifically focus on in-network caching of Peer-to-Peer (P2P) content objects for improving both service and operation efficiencies. We propose an intelligent in-network caching scheme of P2P content chunks,...
The design process is driven by product information in nature. The common workflow model is usually pre-defined and not flexible for the dynamic design process. A new product model-based design process modeling technique is proposed. Product model is defined as design entities, domain models, parameters, and revisions. Data node is added to workflow model to represent input and output information...
Web services are a service-oriented architecture that has gradually advanced in recent years. Offering such benefits as protocol interoperability, complete independence from platforms and languages, and high degree of loose coupling, they have become an increasingly important way for seamless application integration. Coupling the characteristics of remote sensing data and genera l principles for designing...
