The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...

The main purpose of this note is to construct almost complex or structures on certain isoparametric hypersurfaces in unit spheres. As a consequence, S1 × S7 S6, and S3 S2 with vanishing first Chern class, are built.

We describe all binary simple homogeneous structuresM in terms of ∅de nable equivalence relations on M , which coordinatize M and control dividing, and extension properties that respect these equivalence relations.

A relational structure R is rainbow Ramsey if for every finite induced substructure C of R and every colouring of the copies of C with countably many colours, such that each colour is used at most k times for a fixed k, there exists a copy R∗ of R so that the copies of C in R∗ use each colour at most
