    Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

    We propose a scheme to revolutionise the synthesis of nanodevices, nanomachines, and, ultimately, functional materials via the positional assembly of molecules and nanoscale building blocks. Computer-directed actuators will be used to drive (with sub-nanometre to sub-Angstrom precision) the elements of a nanosystem along pre-defined and entirely deterministic trajectories, thereby achieving structures not accessible by mimicking natural assembly strategies alone. Linkages and bonding between the building blocks will also be initiated, modulated, and - in some cases - terminated by direct computer control. Our proposal rests on the parallel development of novel surface-bound, reconfigurable nanoscale building blocks (molecules, functionalised clusters, nanoparticles) and advanced techniques for automated assembly of matter. We focus on the generation of two major and immensely challenging functionalities for positionally-assembled nanomachines: switchable energy transduction and conformationally-driven motion. Our archetypal system comprises the following units: an energy harvester, a switchable/gateable link, and an optical or mechanical output. By arranging, configuring, and triggering these fundamental units our long-term goal is no less than the fabrication of an autonomous, abiotic nanomachine.

    Meaningful information is a fundamental requirement for informed, logical and reasoned activity. Extracting meaningful information from data can, however, be a challenge, especially given problems that data may, amongst other things, be inaccurate, incomplete, and possibly contradictory as arise from a variety of sources of variable quality and trust level. Data imperfections are a generic problem in information extraction and decision making and so the work is relevant in many disciplines. Imperfect data are, for example, evident in medical diagnosis (e.g. a patient's test results are typically only an imperfect indicator of a condition), in defining nature reserves for species conservation (e.g. the species distribution maps and models are often highly sensitive to 'absence' data - was the species actually present but not observed?) and in security and defence applications (e.g. sub-pixel target detection algorithms applied to surveillance imagery vary in performance and utility between environments). Some problems with imperfect data were recently highly apparent in relation to the response to the Haiti earthquake of 2010, especially in relation to damage mapping to inform relief activities. Vast amounts of well-intentioned assistance was provided by numerous professional and amateur bodies with unprecedented data rates but the volumes of data and the problems with them were a concerns. Key problems were that maps were inaccurate, inconsistent and sometimes contradictory. As such a major mapping challenges arises in how to work with such data. One key issue is the need for information on the accuracy of data sources and methods to help use imperfect data. This project seeks to contribute to this task. It aims to illustrate the impacts of using imperfect data, explore methods to characterise the quality of the data and methods to combine data sources to yield an enhanced product of known accuracy. A range of methods will be used but the core focus is on the use of latent class modelling. This type of analysis is based on multiple observations or data from a variety of sources. The relationships between the observers/data sources are used to attempt to explain their quality and suggest how the data could be interpreted to yield information. The approach is a form of statistical modelling and is highly attractive for the specific research proposal because if a model can be formed that fits the observed data, then model's parameters define the accuracy of the data sources and its outputs can be used to form new products of known accuracy. As such the modelling analysis may add value to data by indicating its quality and combining it usefully for extraction of information. As the problems of imperfect data are generic the proposal has broad potential impacts. For the specific DaISy call there are clear impacts in relation to security and defence. For example methods that enable rapid and qualified information to be derived from sources of variable accuracy, completeness and trust level will increase effectiveness and the quality of decision making. Additionally as a model based approach it removes/reduces the need for reference data to be acquired for validation which could otherwise require deployment of personnel to dangerous locations and so of considerable benefit to health and well-being.
