The overall aim of LoCoMaTech is, in the first place, to enable the novel HFQ process, (patented by ICL) in its latest most advanced form, which includes 10 recently patented refining technologies (TRL4), to be used for the manufacture of lightweight, high strength body and chassis structures and components for low-cost vehicles, by establishing a prototype, full scale pilot production line (TRL6), supported by a supply chain ranging from raw material to end of life. This will be the first low-cost technology in the world enabling manufacture of high-strength lightweight complex-shaped aluminium parts and low environmental impact. The 1st generation of HFQ technology has already been commercially used in manufacturing 4 types of niche vehicles. This project aims at bringing the materials and manufacturing cost significantly down, through introducing newly patented technological measures, by which the technology could be used for producing low-cost vehicles. The low-cost HFQ technology will be used first for mass production of aluminium car body and chassis structures (eventually for all vehicles), which will lead to substantial improvement in energy efficiency, performance and travel range of low-end vehicles. LoCoMaTech will construct a world first low-cost HFQ aluminium production line (prototype), targeting reduction of energy consumption per vehicle by 15.3-22%, and cost-effective weight savings from 8.55 to 2.16 /kg-saved and improvement of LCA environmental impact by 15.39-26.8%. LoCoMaTech plans to assist in creating 53 commercial production lines and 1700 jobs, in year 6 from the completion of the project. The potential market for low-cost HFQ technology for passenger cars alone is over 160 billion pa, and double this, if buses, trucks, trains and aircraft are considered. This will create huge wealth for Europe and place European automotive industry in a world leading position for lightweight manufacturing technologies for low-end vehicle production.

This Centre for Doctoral Training in Embedded Intelligence, the first in the UK, addresses high priority areas for economic growth such as autonomous complex manufactured products and systems, functional materials with high performance systems, data-to-knowledge solutions (e.g. digital healthcare and digitally connected citizens), and engineering for industry, life and health, which are also key priorities for Horizon 2020, the new EU framework programme for research and innovation. Horizon 2020 explicitly spells out ICT and Manufacturing as key industrial technologies. Its remit fits the EPSRC priority areas of ICT for Manufacturing and Data to Knowledge, and has an impact on industrial sectors as diverse as logistics, metrology, food, automotive, oil & gas, chemistry, or robotics. In addition, our world (homes, transport, workplaces, supplies of food, utilities, leisure or healthcare) is constantly seeking for interactive technologies and enhanced functionalities, and we will rely on these graduates who can translate technologies for the end-user. The uniqueness of this Centre resides on the capability to innovatively address a myriad of Embedded Intelligence challenges posed by technical needs ranging from the EI supply chain: the design stage, through manufacturing of embedded or on-bedded devices, to the software behind data collection, as well as integrative technologies, to finally the requirements from end-users. The thematic areas, discussed conjointly with industry during the preparation of this proposal, allow us also to recruit students from a vast range of educational backgrounds. A strong user pull defines the nature of the challenges that this CDT will tackle. The graduates who shall come to alleviate the shortage of skilled engineers and technologists in the field will be exposed to the following thematic areas: > Device design, specification of sensors and measurement devices (power scavenging, processing, wire & wireless communications, design for low power, condition monitoring); > Packaging & integration technologies (reliability and robustness, physical and soft integration of devices, sub-components and wider system environment); > Intelligent software (low level, embedded, system level, database integration, ontology interrogation, service oriented architectures, services design); > Manufacturing solutions (design for manufacture of embedded systems, advanced and hybrid manufacturing processes for embedding, process consolidation technologies, biomimetics and cradle-to-cradle for sustainability production, etc.); > Applications engineering (design and implementation of embedded technologies for in-time, in-line products, processes and supply chains; product and process design for embedded intelligence); > System Services: (i) Service Foundations (e.g., dynamically reconfigurable architectures, data and process integration and semantic enhanced service discovery); (ii) Service Composition (e.g. composability analyses, dynamic and adaptive processes, quality of service compositions, business driven compositions); (iii) Service Management and Monitoring (e.g. self: -configuring, -adapting, -healing, -optimising and -protecting) and (iv) Service Design and Development (e.g. engineering of business services, versioning and adaptivity, governance across supply chains). Our flagship, the Transition Zone training, will facilitate the transition into doctoral studies in the first year of studies, and, closer to the end of the programme, out to industry or self-employment. As employable high calibre individuals with a good understanding of enterprising, commercialisation of research, social responsibility, gender equality and diversity, innovation management, workplaces, leadership and management, our doctorates will grow prosperity bottom up, enjoying a wealthy network of academic and industrial contacts from their years at the CDT, as well as their peers at the Centre.
