Innovation Policy Roadmapping for the Future Finnish Smart City Digital Twins : Towards Finland National Digital Twin Programme

Smart City Digital Twins (SCDTs) emerge as a transforming concept with the ability to redefine the future of cities in the fast-paced evolving landscape of urban development. This qualitative futures research explores thoroughly into the complex interaction of socio-technical dynamics in the Finnish setting, investigating the several ways SCDTs might revolutionise urban spaces and create resilience. By utilizing Innovation Policy Roadmapping (IPRM) method for the first time on SCDTs, it reveals the diverse capacities of SCDTs across domains such as urban planning, scenario developing, What-IF analysis, and public involvement through a rigorous examination of academic literature and multi-level analysis of expert interviews. The research emphasises the critical role of policymakers and sectoral actors in building an environment that allows Finnish SCDTs to survive in the face of technological improvements. Furthermore, it emphasises the convergence of SCDTs and Futures Studies approaches, giving a visionary path to adaptable and forward-thinking urban futures. The contributions of this study extend beyond the scope of Finnish SCDTs, giving inspiration for sustainable smart city transformations, potential foundational insights towards Finland National Digital Twin Programme and paving the way for the incorporation of futures studies methodologies and digital twins to mitigate uncertainties and create resilient urban futures. Longitudinal impact assessments, real-time citizen-centric foresight applications via SCDT, and the investigation of SCDTs' role in disaster mitigation and social well-being are among the identified future research directions, providing a comprehensive roadmap for leveraging SCDTs as transformative tools for building sustainable urban futures

Dual Queue Coupled AQM: Deployable Very Low Queuing Delay for All

On the Internet, sub-millisecond queueing delay and capacity-seeking have traditionally been considered mutually exclusive. We introduce a service that offers both: Low Latency Low Loss Scalable throughput (L4S). When tested under a wide range of conditions emulated on a testbed using real residential broadband equipment, queue delay remained both low (median 100--300 $\mu$s) and consistent (99th percentile below 2 ms even under highly dynamic workloads), without compromising other metrics (zero congestion loss and close to full utilization). L4S exploits the properties of `Scalable' congestion controls (e.g., DCTCP, TCP Prague). Flows using such congestion control are however very aggressive, which causes a deployment challenge as L4S has to coexist with so-called `Classic' flows (e.g., Reno, CUBIC). This paper introduces an architectural solution: `Dual Queue Coupled Active Queue Management', which enables balance between Scalable and Classic flows. It counterbalances the more aggressive response of Scalable flows with more aggressive marking, without having to inspect flow identifiers. The Dual Queue structure has been implemented as a Linux queuing discipline. It acts like a semi-permeable membrane, isolating the latency of Scalable and `Classic' traffic, but coupling their capacity into a single bandwidth pool. This paper justifies the design and implementation choices, and visualizes a representative selection of hundreds of thousands of experiment runs to test our claims.Comment: Preprint. 17pp, 12 Figs, 60 refs.

Measuring and modelling towline responses using GPS aided inertial navigation

The offshore towage of large floating structures has been the broad subject of research since the 1960’s. The selection of a tug to engage in a tow is based on rules laid down by class and marine warranty surveyors derived from years of experience but a rigorous assessment of these rules based on a comprehensive real world datasets has not been possible. This is principally due to the nature of these tows, usually employing tugs chartered at short notice from the spot market, the long towline lengths when under tow and the high value of the tow itself. Given the commercial implications in being able to better match a suitable tug to any given tow, this research lays down the requirements of an ideal dataset, i.e. one that has a record of towline tensions, complete 6DOF of both the tug and tow all recorded to a universal timeline, along with the seastate experienced by the tow at any given point. It then reviews the historical restrictions in gathering this data and that the key issue has been gathering the motions of the unpowered tow and recording the towline tensions.A methodology is then developed which requires no interference with the towline and draws upon Kalman filters for optimal state estimation of the tug and tow’s position and attitude in 3D space driving a lumped mass simulation of the towline coded in MatLab. The stiffness properties of key elements of the towline are assessed by FEA and observations made on areas where normal industry practice’s may be lacking. Observations on advances in sensor technology as well as other areas for development are then made that provide fertile areas for further research. Finally the full code base for a MatLab, lumped mass simulator is presented in an appendix for future use.The offshore towage of large floating structures has been the broad subject of research since the 1960’s.

Macroeconomic Policy Advice and the Article IV Consultations: A European Union Case Study

The IMF makes policy recommendations to European countries through its Article IV consultations and resulting papers. This paper examines IMF policy recommendations to see whether they have contributed to the ongoing crisis in Europe, and also how they might affect other European Union goals such as those of Europe 2020, which seeks to reduce social exclusion, promote public investment in research and development, and promote employment and education.The paper examines the policy advice given by the IMF to European Union countries in 67 Article IV agreements for the four years 2008-2011 (IMF 2012c).Content analysis finds a consistent pattern of policy recommendations, which indicates (1) a macroeconomic policy that focuses on reducing spending and shrinking the size of government, in many cases regardless of whether this is appropriate or necessary, or may even exacerbate an economic downturn; and (2) a focus on other policy issues that would tend to reduce social protections for broad sectors of the population (including public pensions, health care, and employment protections), reduce labor's share of national income, and possibly increase poverty, social exclusion, and economic and social inequality as a result.Europe remains mired in its second recession in three years, and the International Monetary Fund's (IMF's) most recent (October 2012) World Economic Outlook (WEO) sees its problems as perhaps the most important drag on world economic growth. The IMF is also part of the so-called "troika" -- with the European Commission (EC) and European Central Bank (ECB) that has been deciding or strongly influencing economic policy in the eurozone, as well as affecting policy in the rest of the European Union, especially since the world economic crisis and recession of 2008-2009. This paper raises questions as to whether the IMF's policy advice has contributed to the ongoing economic problems in Europe

Decoupling Information and Connectivity via Information-Centric Transport

The power of Information-Centric Networking (ICN) architectures lies in their abstraction for communication --- the request for named data. This abstraction promises that applications can choose to operate only in the information plane, agnostic to the mechanisms implemented in the connectivity plane. However, despite this powerful promise, the information and connectivity planes are presently coupled in today\u27s incarnations of leading ICNs by a core architectural component, the forwarding strategy. Presently, this component is not sustainable: it implements both the information and connectivity mechanisms without specifying who should choose a forwarding strategy --- an application developer or the network operator. In practice, application developers can specify a strategy only if they understand connectivity details, while network operators can assign strategies only if they understand application expectations. In this paper, we define the role of forwarding strategies, and we introduce Information-Centric Transport (ICT) as an abstraction for cleanly decoupling the information plane from the connectivity plane. We discuss how ICTs allow applications to operate in the information plane, concerned only with namespaces and trust identities, leaving network node operators free to deploy whatever strategy mechanisms make sense for the connectivity that they manage. To illustrate the ICT concept, we demonstrate ICT-Sync and ICT-Notify. We show how these ICTs 1) enable applications to operate regardless of connectivity details, 2) are designed to satisfy a predefined set of application requirements and are free from application-specifics, and 3) can be deployed by network operators where needed, without requiring any change to the application logic

Mobilizing city-regional urbanization: The political economy of transportation and the Production of the metropolis in Chicago and Toronto

Studies of cities and urbanization are confronted with significant theoretical and methodological challenges as the urban question is reposed at the city-regional scale. Normative understandings of city-regions as sites of economic innovation and distinct political actors on the world stage belie the complex processes underlying their production. This has significant implications for social justice and political practice. This dissertation engages the challenges of city-regional urbanization through a critical comparative analysis of urban transportation institutions and infrastructure in the Chicago and Toronto city-regions. Focusing on long-term historical and spatial structures, the study demonstrates how multiscalar political, economic and social processes crystallize in specific urban formations and in tum, how processes of urbanization shape urban governance and practices of everyday life. The dissertation develops three central theoretical innovations. First, it introduces a geographical historical-materialist comparative framework to examine the contingent evolution of city-regional formations in space and across time using a cross-national perspective. Second, it reframes urban transportation as a key realm of political economy inquiry, redressing the limitations of traditional transportation geography and the poststructural approaches which dominate urban infrastructures literature. Third, it incorporates diverse urban, suburban and post-suburban spaces within an overarching theorization of city-regional urbanization as an expression of centripetal and centrifugal forces. Qualitative methods are used to uncover and analyze socially-entangled and geographically-disparate urban relations. The empirical analysis reveals that the prioritization of particular scales of mobility spurs the emergence of new city-regional topologies which do not neatly align with territorially-defined forms of state space. Strategies of regionalization are as likely to open new fissures in city-regional space as they are to fuse collective regional agency. The convergences and divergences witnessed between the Chicago and Toronto city-regions illustrate the place-specific path dependent properties of institutional and infrastructure fixes that highlight the importance of historically and geographically sensitive comparative research. The dissertation's dialectical and comparative contributions open the city-region as a multifaceted, multiscalar and multilayered object of analysis. It concludes by outlining how the study's dialectical approach to city-regional urbanization can inform debates on urban transformation and social change
