Car-to-car and car-to-infrastructure communications are currently under intense research as they enable a wide variety of applications. Besides security-driven applications which require only small amounts of individual data there are also applications which require medium to high amounts of uniform data delivered to an unknown number of nodes. For this kind of broadcast and multicast applications, the use of fountain codes is highly suitable. In this paper, we investigate the applicability of fountain codes in an infrastructure-based automotive communication system and introduce an expedient method to design a system deploying IEEE 802.11p and fountain codes. By means of simulation results obtained for three representative vehicular scenarios we compare the performance of our method to an alternative method also applied in this field, i.e. the data carousel. For specific configurations the system based on fountain codes outperforms the conservative approach by a factor of four in terms of the overall throughput and thus provides the potential to significantly increase the overall efficiency.

This work focuses on the measuring and modeling of phase equilibria of interest for the hydroaminomethylation of 1-decene with syngas (CO/H2) and diethylamine to N,N-diethylundecan-1-amine and water in a solvent system of methanol and n-dodecane. H2 solubilities were measured in undecanal and N,N-dimethyldodecan-1-amine at 343 and 363 K between 2 and 4 MPa via the isochoric saturation method. Vapor–Liquid equilibrium data were measured for the binary systems methanol/N,N-diethylundecan-1-amine, 1-decene/diethylamine, and 1-decene/N,N-diethylundecan-1-amine at temperatures between 299 and 372 K and at pressures of 0.005, 0.018, 0.025, or 0.030 MPa. Liquid–Liquid equilibria were measured in the ternary systems methanol/n-dodecane/diethylamine, methanol/n-dodecane/undecanal, and methanol/n-dodecane/N,N-diethylundecan-1-amine at 0.1 MPa and at temperatures ranging from 278.15 to 308.15 K. Measured and available phase-equilibrium data from literature were modeled using perturbed-chain polar statistical associating fluid theory. This then allowed for modeling the Henry’s law constant for H2 and CO in the liquid components (methanol, n-dodecane, 1-decene, diethylamine, undecanal, N,N-diethylundecan-1-amine, and water) at 373.15 and 393.15 K.

Dès le début de Earth, la cinéaste Deepa Mehta établit un parallèle entre une assiette fracassée, un pays morcelé et le corps endommagée de la jeune Lenny. Par un décodage idéologique de ce physique infirme, la réalité corporelle vécue de ce corps échappe au regard critique. Ôn ne remet pas en question la gestion et le positionnement du corps perclus, qui n'est qu'une métaphore de la gestion et du positionnement postcoloniaux. Le corps de Lenny est empreint de dystrophie. On la réprimande et la tourmente. Les personnages non-handicapés la bousculent. Ce qui illustre le champ social qui démarque Lenny. Pour ces personnages, comme pour le spectateur, le corps de Lenny est une surface qui évoque le « schéma » aristotélicien or le « réceptacle » platonicien, et il est ainsi hors de lui-même. Quand Judith Butler explique que le corps importe, elle note que « ce qui constitue la fixité du corps … sera repensé sous l'action du pouvoir. » Earth nous permet d'explorer l'inscription du pouvoir sur le corps.
