Broom fibers have been used as reinforcement for the conventional polypropylene (iPP) and a maleate modified one (iPPMA). A alkaline treatment steam explosion extraction process were applied to obtain cellulosic material from broom branches. Composites prepared by melt mixing materials with different weight percentages of fibers. Also ternary blends (iPPMA/iPP/broom 5/45/50 wt) obtained examine possibility utilizing compatibilizing agent. The composites thermally, morphologically,...
A discrete system constituted of particles interacting by means a centroid-based law is numerically investigated. The elements the move in plane, and range interaction can be varied from more local form (first-neighbours interaction) up to generalized nth order interaction. aim model reproduce behaviour deformable bodies with standard (Cauchy model) or (second gradient) deformation energy density. numerical results suggest that considered effectively first second gradient continua. Moreover,...

Abstract Composites of wheat straw fibers with polypropylene (iPP) and maleic anhydride modified (iPPMA) were prepared. Before being mixed matrices, the subjected to a steam explosion process that induces morphological structural changes in lignocellulosic materials. Such are able enhance interactions thermoplastic matrix. Compared iPP, matrix has shown higher mechanical performances (tensile impact behavior) remarkable decrease water absorption, is one main drawbacks natural fiber...

The subject is the localization problem of an underwater swarm autonomous robots (AUV), in frame HARNESS project; by localization, we mean relative configuration, i.e., geometrical shape group. result achieved using signals that exchange. organized rules and conceived to perform tasks, ranging from environmental monitoring terrorism-attack surveillance. Two methods determining swarm, both based on trilateration calculation, are proposed. first method focuses robot's speed. In this case, use...

Abstract Vegetable fibers deriving from the basts of broom plants have been used as reinforcement for two polypropylenic matrices: a conventional isotactic polypropylene (iPP) and maleate modified one (iPPMA). Before mixing were subjected to different extraction procedures: alkaline treatment an innovative steam explosion process. Afterwards, composites obtained by compression moulding thermally, morphologically, mechanically characterized. Moreover, water absorption tests, examine behaviour...
Abstract In a preceding paper, we have showed as swarm robotics displacement can be related to the deformation of continuum material, discretized by lattice network representing swarm. To reach this aim, it is fundamental know configuration, i.e., its shape; computed from knowledge relative distances between elements and studied geometry problem. Typically, ultrasonic devices are employed measure distances. We propose method based on light signal exchanged machines computing unknown water...
