A fault-tolerant data processing computer system and method for implementing a distributed two-tier state machine aimed for distributed (replicated) data stores, in which consistency is maintained despite the failure of any number of replicas and communication paths. In the distributed two-tier state machine, one process (device) in a network of processes (devices) is chosen as the leader, and that leader is responsible for executing functions that return state machine commands, and for broadcasting the commands to the other processes. The processes execute the commands in the logical precedence order that corresponds to the order of function executions that return these commands. The system and method ensures that each of the processes issues exactly the same sequence of commands for execution, such that each command in the sequence, except the first one, has a precedent command on which the command logically depends.

In order to realize sustainable mobility in Europe, both urban and long distance vehicles for road transport will have to be significantly more efficient by 2020\ and a considerable contribution will have to come from the energy efficiency improvement of the powertrain. Moreover, together with the progressive efficiency increase coming from the engine technology evolution, the use of Low-Carbon Alternative Fuels, such as Natural Gas, will play a fundamental role to accelerate the process of decarbonization of the transportation sector that in Europe is targeted for the 2050 time horizon. In this context, being well-known the benefits of the Natural Gas Vehicles adoption in Europe, this proposal aims to exploit the main benefits of gas-powered engines developing CNG-only, mono-fuel-engines able to comply with: post Euro 6 noxious emissions 2020\ CO2 emissions targets new homologation cycle and Real Driving conditions and simultaneously improving engine efficiency and vehicle performance also with regard to its CNG range capability. These engines, based on new combustion processes, require also dedicated technological solutions for: Innovative injection, ignition and boosting system concepts Advanced exhaust gas aftertreatment system Detecting the gas-quality and its composition The results obtained from the experimental activities on the demonstration vehicles and engines will be harmonized and analysed throughout a final overall assessment of the different approaches. The demonstrator vehicles will be assessed in terms of performance and emissions with regard to NEDC, WLTP and under real driving conditions. Moreover, the final assessment of the vehicles will be certified, as independent testing, by JRC (Joint Research Centre) which will carry out additional measurements in their own testing facilities both on chassis dyno and by means of PEMS (Portable Emissions Measurement System).

DESTINATE aims to develop tools and methodologies for railway noise simulation and cost-benefit analysis of mitigation actions of interior and exterior noise. For accurate noise prediction it is essential to characterize the structure-borne and airborne sound sources accurately in order to create valid input for sound prediction simulation models. The calculated interior and exterior noise can be auralised and visualised in a studio to evaluate the sound quality and sound comfort of potential mitigation measures in the vehicle design process. Auralisation and visualisation of noise can be used to assess the annoyance reduction of a given measure. Thus human perception is adequately taken into account. For decision-making the cost of different design options is a very important parameter. DESTINATE aims to further develop cost effectiveness prediction and thus create the foundation for powerful tools to support decision-making on noise & vibration mitigation measures.

The exponential growth of mobile traffic, drastically increasing of network complexity, and the strong need for inter-network coordination of wireless network resources call for breakthroughs in control, coordination and flexible spectrum management in 5G heterogeneous radio access networks. The COHERENT project aims to address these problems by researching, developing and validating a novel control framework for future mobile networks. The key innovation of COHERENT is to develop a unified programmable control framework to coordinate the underlying heterogeneous mobile networks as a whole. The COHERENT control framework has two unique features to deal with the insufficiency of current control solutions for inter-network coordination. First, theories and methods to abstract the low layer network states and behaviors of different underlying mobile networks are developed, which provides a simplified but sufficient abstracted network view for network-wide control and resource coordination. Network abstraction will significantly reduce the signaling overhead, making scalable network-wide control solutions feasible, and enable more flexible spectrum management, which are key for the success of 5G networks. Second, based on the abstracted network view, common interfaces and software-development kits will be developed to enable programmability in controlling and coordinating heterogeneous mobile networks. The programmable control will provide operators a flexible and cost efficient way to implement new control functions and thus to support new services. The innovative impact of the COHERENT project is in enabling a unified control and coordination framework for heterogeneous mobile networks by combining innovative approaches on abstraction of low layers in underlying mobile networks, software defined networking, and flexible spectrum management. COHERENT will build a true proof-of-concept prototype to demonstrate the applicability and benefits of its approach.


Metal ion release from metallic materials, e.g. metallic alloys and pure metals, implanted into the human body in dental and orthopedic surgery is becoming a major cause for concern. This review briefly provides an overview of both metallic alloys and pure metals used in implant materials in dental and orthopedic surgery. Additionally, a short section is dedicated to important biomaterials and their corrosive behavior in both real solutions and various types of media that model human biological fluids and tissues. The present review gives an overview of analytical methods, techniques and different approaches applied to the measurement of in vivo trace metals released into body fluids and tissues from patients carrying metal-on-metal prostheses and metal dental implants. Reference levels of ion concentrations in body fluids and tissues that have been determined by a host of studies are compiled, reviewed and presented in this paper. Finally, a collection of published clinical data on in vivo released trace metals from metallic medical implants is included. © 2014 Acta Materialia Inc. Published by Elsevier Ltd.
