No full textA non-linear subdiffusion model for a cell-cell adhesion in chemotaxis
No full textThe purpose of this work is to propose a non-Markovian and nonlinear model of subdiffusive transport that involves adhesion affects the cells escape rates form position x, with chemotaxis. This leads the escape rates to be dependent on the particles density at the neighbours as well as the chemotactic gradient. We systematically derive subdiffusive fractional master equation, then we consider the diffusive limit of the fractional master equation. We finally solve the resulted fractional subdiffusive master equation stationery and analyse the role of adhesion in the resulted stationary density

No full textStability analysis for time-dependent nonlinear systems. An interval approach
No full textOne of the most important issues in control is determining the stability of a system. Since the 1960’s, Lyapunov-based methods have been developed to determine the stability of linear and nonlinear systems. However, when the system is nonlinear, time-dependent and uncertain, in a set-membership context, stability analysis is challenging and no reliable methods have been developed. This paper proposes an original set-membership based approach for establishing the stability of non-linear, uncertain, time-dependent systems. Two new concepts G-Stability (which is the stability of nonlinear time-dependent uncertain trajectories) and capture tubes (which is an invariant stability region for time-dependent systems) are introduced and illustrated for an autonomous, uncertain, robotic sailboat. Then, G-Stability is used to formulate and prove the safety for a set of capture tubes. This result is then used to analyse the safety of a squad of uncertain, robotic sailboat moving in their environment (no collision among the robots)
Modelling, assessment and Sankey diagrams of integrated electricity-heat-gas networks in multi-vector district energy systems
No full textThe widespread use of decentralised multi-energy supply solutions such as gas-fired Combined Heat and Power (CHP), heat pumps, gas boilers, and so forth is more and more increasing the linkages between electricity, heat and gas distribution networks. However, there is currently no model able to model the three networks in an integrated manner and with a suitable level of detail for operational purposes. A multi-temporal simulation model, which has been implemented in a relevant MATLAB-Excel VBA tool, is presented in this paper to carry out integrated analysis of electricity, heat and gas distribution networks, with specific applications to multi-vector district energy systems. The network linkages have been modelled through a multi-vector efficiency matrix specifically developed to map the transformation of final demands into network energy flows while taking into account the inter-network locations of the individual supply technologies. The relevant coupled electrical, heat and gas flow equations have been solved simultaneously using a Newton-Raphson approach. A real case study of a district multi-energy system in the Campus of the University of Manchester illustrates the quantitative use of the model in different scenarios for technical, economic and environmental studies. Sankey diagrams of the energy flows across the networks are also presented to give a visual picture of the multi-energy interactions and losses in the district in different scenarios. The model can be flexibly adapted to generic network topologies and multi-energy supply technologies, and can thus be used for practical operational implementations as well as to inform planning of low carbon multi-vector energy systems
Politics and Eschatology: Reassessing the Appeal of the “Jewish Indian” Theory in England and New England in the 1650s
No full textThis article examines the “Jewish Indian” theory— which claimed that American Indians were the ten lost tribes of Israel— in 1650s England and New England. The theory found support in England while failing in New England. This difference in reception can be explained by considering its ecclesiological, political, and eschatological implications. Biblical commentators in both England and New England held to a form of “Judeo-Centric” eschatology, which looked for a sudden, miraculous conversion of the Jews and their eventual superiority to Gentile believers. Such beliefs undermined crucial elements of New England ecclesiology when applied to Native Americans. Conversely, the New England Company used the theory in its publications as a fund raising tool in England. These publications impacted upon debates on Jewish readmission to England in the mid-1650s, with New England missionary models suggested as a way of evangelising Jews. This article therefore argues for the importance of understanding eschatological beliefs in local contexts, while demonstrating the way in which such beliefs can be maintained and reoriented in the face of apparent disconfirmation
Open innovation evaluation for Internet-enabled services in smart cities
No full textThis article is focused on public service innovation from an innovation management perspective. It presents research experience gained from a European project for managing social and technological innovation in the production and evaluation of demand-driven internet-enabled services in the public sector. It is based on 5 pilot initiatives, which sought to operationalise a new approach to co-producing and co-evaluating civic services in smart cities – commonly referred to as open innovation for smart city services. Research suggests that the evidence base underpinning this approach is not sufficiently robust to support claims being made about its effectiveness. Instead evaluation research of demand-driven internet-enabled urban services is in its infancy and there are no tested methods or tools in the literature for effectively supporting this approach. The paper reports on the development and trialling of a Co-evaluation Framework, indicators and reporting categories, used to support the co-production of citizens-driven smart city services in an EU-funded project. Our point of departure is that innovation of services is a sub-set of innovation management that requires effective integration of technological with social innovation, supported by the right skills and capacities. The main skills sets needed for effective co-evaluation of open innovation services are the integration of stakeholder management with evaluation capacities
