A shock absorber for a vehicle is disclosed which has a pressure tube defining a fluid chamber, a piston rod, and a piston disposed within the fluid chamber, and carried on the piston rod, which divides the fluid chamber into upper and lower working chambers, and which has a plurality of passages extending between the upper and lower working chambers. A valve disc assembly controls a flow of fluid, and includes a spring disc. The spring disc has a non-symmetrical circumferential shape which enables a stiffness of the valve disc assembly to be tailored so that it begins to open at a first peripheral point, and continuously gradually opens about a non-symmetrical circumferential path until reaching a second peripheral point adjacent the first peripheral point.

Wear and corrosion of materials causes losses of 3-4% of GDP in developed countries and billions of Euros are spent annually on capital replacement and control methods for wear and corrosion infrastructure. As a result many important industries are dependent on surface engineering of protective coatings, making it one of the main critical technologies underpinning the competitiveness of EU industry. There are 2 main techniques that dominate the protective coatings sector: hard chromium (HC) plating and thermal spray (TS). However, HC plating faces a series of issues with most important the extremely negative health and environmental impact leading to the EC restriction of this method for using Cr\6 by the end of 2017. Similarly, recent toxicity studies concerning Co-WC cermet applied by TP have revealed that Co-WC particles are toxic in a dose/time-dependent manner. Consequently, there is the necessity of finding new, less hazardous methods and materials exhibiting the same or better performance compared to existing ones. The PROCETS project will took advantage of the use of nano-particles for production of composite coatings with superior properties compared to those of HC produced by electroplating or to Co-WC produced by TS. These novel nano-particles will be incorporated into existing production lines after appropriate modifications. The new procedures will be easily transferred by minor adaption to the present electroplating and TS facilities, and will combine flexibility and mass customization abilities, restrict environmental and health hazards and finally be available at acceptable cost. Thus, PROCETS main target is to deliver protective coatings covering a wide range of applications such as automotive, aerospace, metal-working, oil and gas and cutting tools industries via thermal spray and electroplating methods by utilizing more environmental friendly materials, compared to the currently used.

The main goal of the CLOVER project is to offer a novel methodology in an environmental mechatronic control system design relying on multidisciplinary knowledge. This methodology should allow aspects to be taken into account, such as controller robustness, indirect measurement of system states and parameters, and disturbances attenuation on the stage of establishing controller architecture. In addition, methods for tuning the control algorithms will be developed and based on the solution of optimization task considering control priorities, such as environment friendliness and energy efficiency. The implementation of the project CLOVER is based on intensive staff exchange that will lead to collaborative research and training between universities and industrial organizations from Germany, Austria, Belgium, Norway, UK, Mexico, and Japan. To guarantee a strong focus of the project activities on real-world problems, the CLOVER concept is based on the R&D and training in three interfacing topics: Mechatronic chassis systems of electric vehicles, Mechatronic-based grid-interconnection circuitry, and Offshore mechatronics, which will identify and facilitate collaborative learning and production of innovative knowledge. The CLOVER objectives will be achieved through intensive networking measures covering knowledge transfer and experience sharing between participants from academic and non-academic sectors, and professional advancement of the consortium members through intersectoral and international collaboration and secondments. In this regard, the CLOVER project is fully consistent with the targets of H2020-MSCA-RISE programme and will provide excellent opportunities for personal career development of participating staff and will lead to the creation of a strong European and international research group to create new environmental mechatronic systems.

Due to the proliferation of ICT Technologies, manufacturing industry is undergoing substantial transformation in terms of HW but also in terms of Cyber-Physical Production Systems and the SW and services used within production environments. In parallel, the manufacturing processes of the future are changing and need to be highly flexible and dynamic in order to satisfy customer demands for, e.g. large series production, mass customization, or changing orders. To keep pace with the needs of the manufacturing industry of the future, in Manufacturing 4.0 companies need to flexibly react to these demands and be able to offer production capacities in a rapid way. Thus companies looking for manufacturing capacity need to be supported by the means to find these capacities, configure them, and integrate them into their own manufacturing processes. To achieve this, one obvious approach is to port successful concepts from the field of Everything-as-a-Service (XaaS) and Cloud computing to manufacturing to mirror agile collaboration through flexible and scalable manufacturing processes: Leasing and releasing manufacturing assets in an on-demand, utility-like fashion Rapid elasticity through scaling leased assets up and down if necessary Pay-per-use through metered service Applying these principles, Cloud manufacturing can move manufacturing processes from production-oriented to service-oriented networks by modelling single manufacturing assets as services in a similar way as SaaS or PaaS solutions. By modelling all process steps and manufacturing assets as services it is possible to realize cross-organization manufacturing orchestrations and integrate distributed resources and ultimately manufacture products more efficiently. While the theoretical foundations for Cloud manufacturing are manifest there are no proven tools and technologies exist in the market - CREMA aims to change this fact by providing Cloud-based Rapid Elastic Manufacturing based on SaaS and Cloud model
