I Certification of a mono or multicore processor is going to request to demonstrate that we are able to master the determinism of the execution for all the applications which are going to be executed. Regarding the multicore we introduce a level of complexity to be managed regarding the execution of the application in parallel on each of the cores of the multicore processor whatever is the internal architecture of the processor. In an IMA context: This determinism is insured by the control of the WCET allowing defining a maximal boundary for all the accesses to all the services offered by the Operating System. The Platform Provider has no information about the applications which are going to be executed by his platform. In this condition the computation of a WCET on a multi-core, like it is done currently on a mono-core, will be realized by introducing constraints at the level of the internal functioning of the multi-core processor.

Abstract Heavy-duty vehicles (HDVs) account for some 5% of the EU’s total greenhouse gas emissions. They present a variety of possible configurations that are deployed depending on the intended use. This variety makes the quantification of their CO2 emissions and fuel consumption difficult. For this reason, the European Commission has adopted a simulation-based approach for the certification of CO2 emissions and fuel consumption of HDVs in Europe; the VECTO simulation software has been developed as the official tool for the purpose. The current study investigates the impact of various technologies on the CO2 emissions of European trucks through vehicle simulations performed in VECTO. The chosen vehicles represent average 2015 vehicles and comprised of two rigid trucks (Class 2 and 4) and a tractor-trailer (Class 5), which were simulated under their reference configurations and official driving cycles.

AS5714A
This SAE Aerospace Standard (AS) prescribes the Minimum Performance Standards (MPS) for wheel, brake, and wheel and brake assemblies to be used on aircraft certificated under 14 CFR Parts 23, 27, and 29. Compliance with this specification is not considered approval for installation on any aircraft.

AS5420G
This SAE Aerospace Standard (AS) covers the requirements for a flexible, lightweight, low pressure, self-extinguishing, integrally heated silicone hose assembly. The hose has a fully fluorinated fluoropolymer inner liner and is primarily intended for use in aircraft potable water systems with an environmental operating temperature range of -65 °F (-54 °C) to +160 °F (+71 °C).

ARP6481
This SAE Aerospace Recommended Practice (ARP) describes a method for assessing size dependent particle losses in a sampling and measurement system of specified geometry utilizing on the non-volatile PM (nvPM) mass and number concentrations measured at the end of the sampling system. The penetration functions of the sampling and measurement system may be determined either by measurement or by analytic computational methods. Loss mechanisms including thermophoretic (which has a very weak size dependence) and size dependent losses are considered in this method along with the uncertainties due to both measurement error and the assumptions of the method. The results of this system loss assessment allow development of estimated correction factors for nvPM mass and number concentrations to account for the system losses facilitating estimation of the nvPM mass and number at the engine exhaust nozzle exit plane.
