Policy evaluation is central to economic data analysis, but economists mostly work with observational in view of limited opportunities carry out controlled experiments. In the potential outcome framework, panel approach (Hsiao et al., 2012) constructs counterfactual by exploiting correlation between cross-sectional units data. The choice control units, a key step its implementation, nevertheles...

Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...

In contrast to feature selection and gene set analysis, bi-level selection is a process of selecting not only important gene sets but also important genes within those gene sets. Depending on the order of selections, a bi-level selection method can be classified into three categories - forward selection, which first selects relevant gene sets followed by the selection of relevant individual gen...

IPsec is a collection of protocols that provides network layer data integrity and confidentiality services. IKEv1 is a versatile key agreement protocol that allows perfect forward secrecy and identity protection (among other things). IKEv2 has similar functionalities as IKEv1, but provides a simpler and better approach to key exchange. Additionally, IKEv2 provides new methods for authentication...

To keep the diversity of antibodies in artificial immune system evolution process, this paper puts forward a kind of increase simulation surname inheritance algorithm based on the clonal selection algorithm, and identification and forecast the Vibration Data about CA6140 horizontal lathe machining slender shaft workpiece prone. The results show that the algorithm has the characteristics of flex...
