An important topic in formal concept analysis is to cope with a possibly large number of formal concepts extracted from formal context (input data). We propose a method to reduce the number of extracted formal concepts by means of constraints expressed by particular formulas (attribute-dependency formulas, ADF). ADF represent a form of dependencies specified by a user expressing relative import...

The paper contains data on sexual size dimorphism of Bufotes sitibundus Pallas, 1771 with samples from the “Greater Caucasus”, “Lankaran” and “Absheron” territories Azerbaijan. 139 adult specimens (62♂ 77♀) 3 populations were collected. They released after morphometric measurements pattern morphs analysis. processed in STATISTICA Stat Soft 10 program. Reliability differences was estimated using...

Fibre metal laminates (FMLs) are lightweight structures with high structural performance and suitable for many industrial applications. This work describes the impact behaviour of novel sisal fibre-reinforced aluminium (SiRAL) their dependence upon orientations fibres, composite core used surface treatment skins. A cold-pressing technique is to produce SiRALs in six configurations. The FMLs her...

This study concerns with the optimisation of a fibre-reinforced composite material ply book and application to an aeronautical component. The presented solution is recyclable FML (Fibre Metal Laminate). Recyclable structural PMCs (Polymeric Matrix Composites) developed up-to now in ENEA had be improved satisfy high-demanding fire characteristics requirements aeronautics, particularly for case c...

Abstract. During the forming of woven fabrics, different multiaxial stress states can occur, depending on given process conditions and complex deformation mechanisms interwoven structure textile. Particularly under constrained conditions, induced e.g. by blank holders or adjacent metal layers in fiber-metal-laminate (FML) forming, may include in-plane compression. A hyperelastic, invariant-base...

Fibre metal laminates (FMLs), as a class of hybrid material taking advantages both metals and composites, have shown great promise lightweight structural materials in the transportation industry. Accordingly, manufacturing technologies FMLs are attracting increasing research interests. This review emphasises developing forming FML components, with other aspects related to being briefly introduc...

The present study investigates the effect of climatic parameters, such as air relative humidity and wind speed, on fire spread propagation indexes in Malekroud Forest, Iran using FARSITE simulator based Rothermel’s original equation. Standard fuel models are used to calibrate vegetation cover. Sorensen (SC) kappa (κ) coefficients, well Overestimation Index (OI), estimate simulation’s accuracy. ...

the idea of combining low weight and good mechanical properties has led to efforts to develop a new light fiber/metal laminate (fml) in the last decade. fmls are hybrid composites consisting of alternating thin layers of metal sheets and fiber-reinforced epoxy prepregs. in this study, the effect of fiber orientation on tensile properties of this material is investigated both analytically and ex...
