As software systems become larger and more complex, developers require the ability to model abstract concepts while ensuring consistency across the entire project. The internet has changed the nature of software by increasing the desire for software deployment across multiple distributed platforms. Finally, increased dependence on technology requires assurance that designed software will perfor...

Date syrup powder is a new product which can be used as sugar substitute. First, the date syrupwas spread out on a foil and placed in the oven at 60°C for 24 hours. Date syrup was separated from the foil andgrinded. 2% agar and 2% starch were added and syrup with agar and starch that was in a lumpy shape werecrushed and spread on the foil and placed at 60°C for 24 hours. Powdered granules, agar...

This paper is concerned with FS-FOIL—an extension of Quinlan’s First-Order Inductive Learning Method (FOIL). In contrast to the classical FOIL algorithm, FS-FOIL uses fuzzy predicates and, thereby, allows to deal not only with categorical variables, but also with numerical ones, without the need to draw sharp boundaries. This method is described in full detail along with discussions how it can ...

In comparison to the traditional solutions, active bearings offer great operating flexibility, ensure better conditions over a wider range of rotational speeds and are safe use. order optimum bearing performance control system is used that adapts different geometries during device operation. The selection optimal controller parameters requires use modern optimization methods make it possible qu...

When applied to the free vibration (modal) analysis of foil-air bearing rotor systems, classical linear force coefficients method (LFCM) can be regarded as an indirect form linearisation that eliminates air film and foil state variables. Research into its accuracy has been limited predictive ability for instability onset speed compared against low amplitude response nonlinear system. Two recent...

Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA maintain this important role. The NASA STI Program Office is operated by Langley Research Center, the Lead Center for NASA's scientific and technical information. The NASA STI Program Office provides ...
