Modelling the vehicle kinematics is an essential design task of integrated navigation systems. It has to consider both the vehicle motion and the mechanical meaning of the used measurements. Up to now, a small rigid body with three translational and three rotational degrees of freedom is almost the only model applied (Farrell, & Barth, 1999). (For car navigation systems another rigid body with ...

We report on a comparison between the random disorder effects of an hydrophobic (R812) or an hydrophilic (A380) aerosil on the order and dynamics of the 3βDOXYL-5α-cholestane spin probe in the liquid crystal 4-n-pentyl-4’-cyanobiphenyl (5CB) using the ESR technique. Increasing the aerosil concentration up to 3 wt % the probe order parameter is depressed with a larger effect for the hydrophilic ...

Synchronous programming is a school of thought in embedded software which has been in the air for a while but without being always given clear and thorough explanations. This has led to many misunderstandings as, for instance, opinions like: “we do not use synchronous programming because null execution time is not realistic and infinitely fast machines do not exist”. At the same time many pract...

GLARE (GLAss REinforced) belongs to a family of fibre-metal laminates currently being used as a skin material for the upper and side shells in the forward and rear fuselage body of A380. This composite material consists of thin layers of aluminium sheets and unidirectional prepreg layers of glass fibres embedded into an epoxy based matrix. GLARE demonstrates excellent resistance to fatigue crac...

The VL (Virtual Link) concept used by AFDX network of modern aircraft such as A380 represents a big assumption for input flows characteristics. But mapping of many VL on a multi switch Ethernet architecture lead to potential congestion on a port of a (given) switch. Thus, there is strong need to prove that no frame will be lost by the network (no switch queue will overflow) and to evaluate the ...
