    Reflections on the relationship between artificial intelligence and operations research

    Get PDF
    Historically, part of Artificial Intelligence's (AI's) roots lie in Operations Research (OR). How AI has extended the problem solving paradigm developed in OR is explored. In particular, by examining how scheduling problems are solved using OR and AI, it is demonstrated that AI extends OR's model of problem solving through the opportunistic use of knowledge, problem reformulation and learning

    From inanimate matter to living systems

    Since the early part of this century, the Genesis account of the origin and evolution of life has been explained as an extrapolation of astronomical and geochemical processes. The essence of the answer to date is a protoreproductive protocell of much biochemical and cytophysical competance. The processes of its origin, molecular ordering, and its functions are described. A crucial understanding is that of the nonrandomness of evolutionary processes at all stages (with perhaps a minor statistical component). In this way, evolution conflicts with statistical randomness; the latter is a favorite assumption of both scientific and creationistic critics of the proteinoid theory. The principle contribution of the proteinoid theory to the understanding of general biology is to particularize the view that evolutionary direction is rooted in the shapes of molecules, in stereochemistry. After molecules of the right kind first assembled to protocells, life in its various stages of evolution was an inevitable consequence. It is molecules that continue to assemble as part of living process and, in the role of enzymes, continue to direct life cycle of the cell

    Tracking the position Global satellite navigations in Europe Expanding man's understanding ‘GALILEO: 2020!’

    Mankind has a thirst to travel and while travel into outer space is a relatively new concept, we increasingly rely, on Earth, on technologies deployed in space to aid our safety, security – including in a transport context, where we look for efficient and effective means. This paper focuses on satellite navigation systems and European undertakings to compete in, what is becoming, an ever-growing, competitive market. The specific focus is on GALILEO – the journey undertaken in terms of endeavouring to make it fully operational by the end of 2020. As part of this, comment and reflection are provided as to the challenges encountered – including Covid-19 and the relationship between the UK and EU. This includes commentary as to the implications of Brexit, in terms of access and use of, and to, European satellite navigation systems. The research-design applied is historical, policy and legislative based. It commences by considering the origins of global navigations systems before the focus is turned to Europe and reviewing the development of GALILEO (alongside EGNOS and the European Global Navigation Satellite Systems Agency). The research finds that a fully operational GALILEO will likely not be achieved in 2020; and, that the UK, whilst contributing massively (both financially and technologically) is unlikely to reap the full benefits of GALILEO

    Policing: Monitoring, Investigating and Prosecuting ‘Drones’

    Get PDF
    The policing role is constantly changing and becoming more challenging, with the UK seeing reduced numbers and financial cuts. Going forward, it is likely that the police will become more involved in the policing of drones. This research looks at the governance of drones from a top down approach – international-regional-national. The legislative complexity is first reviewed before investigating the blurring of roles between Aviation Administration-Authorities and the police. Focus is given regionally to the EU and nationally to the UK with a comparison study of the USA. The research considers the developing remit of the police and who should police drones at a national level. The research finds that currently, the police are under-trained in this subject area and there is insufficient coordination with the national Aviation Authorities
