The High Level Architecture (HLA) defines a federation as a group of simulators. The HLA does not define relations between federations. This makes any complicated structure of a system flat. The absence of hierarchy may bring several issues related to data exchange, security and reusability. The paper proposes the Hierarchical HLA that defines hierarchical relationship between federations. The ...

abstract— due to the daily mass production and the widespread variation of medical x-ray images, it is necessary to classify these for searching and retrieving proposes, especially for content-based medical image retrieval systems. in this paper, a medical x-ray image hierarchical classification structure based on a novel merging and splitting scheme and using shape and texture features is prop...

Recently, deep learning (DL)-based hyperspectral image classification (HSIC) has attracted substantial attention. Many works based on the convolutional neural network (CNN) model have been certificated to be significantly successful for boosting performance of HSIC. However, most these methods extract features by using a fixed kernel and ignore multiscale ground objects images (HSIs). Although ...

bilevel linear programming  is a decision making problem with a two-level decentralized organization. the textquotedblleft leadertextquotedblright~ is in the upper level and the textquotedblleft followertextquotedblright, in the lower. making a decision at one level affects that at the other one. in this paper, bilevel linear programming  with inexact parameters has been studied and a method is...
