This study focuses on the identification of aerodynamic coefficients through airdrop data based a known six-degree-of-freedom (6-DOF) model. Since precise modelling parafoil system is prerequisite for design guidance, navigation and control systems, accurate calculation vital. paper first presents rigid 6-DOF nonlinear model simplifies it by linearizing equations around equilibrium point, which...

Today, effective management of information requires an in-depth study its internal organization. The structural organization affects the efficiency choosing a method for solving problem and qualitative presentation about subject area. Therefore, article proposes new semiotic approach to assessing structuredness in area, as well theoretical, practical, general logical methods studying process se...

Medical image classification as an important research topic both in image processing and biomedical engineering. The ridgelet transform has good directional selective ability to locally and sparsely in representing the image compared with the traditional wavelet transform. This paper proposes a novel classification model for medical image, which is using ridgelet transform and dynamic fuzzy the...
