Enabling connectivity for tactical networks in mountainous areas by aerial relays

The dimension of the Meiac as a diffuser of Latin American art has been key in Spain in the late twentieth century. The genesis of the museum, its cultural policy of debate and diffusion, and the creation of a Latin American collection, which until then did not exist in Spain, forced Spanish art criticism to look at and reconsider work from Latin America. At present the Meiac has developed the new technological platforms, as a new perspective of identity and common imaginaries between Spain and Latin America.La dimensión del Meiac como difusor del arte latinoamericano ha sido clave en España a finales del siglo XX. La génesis del museo, su política cultural de debate y difusión y la creación de una colección latinoamericana, hasta entonces inexistente en España, obligó a la crítica artística española a mirar y a reconsiderar la obra procedente de Latinoamérica.

Enabling connectivity for tactical networks in mountainous areas by aerial relays

A general modeling framework for realistic performance evaluations of tactical mobile ad-hoc networks deployed in mountainous areas is presented. The framework is easily extensible, and can be eventually automated. It can be also used to generate data for other network simulators. The framework utilizes the freely downloadable high resolution 3D terrain data to define time dependent trajectories of network nodes. The node speeds and directions are linked to the terrain profile which extends the previously proposed mobility models. The path-loss analysis along the node trajectories revealed the need for aerial relays to enable full network connectivity at all times. The network consisting of 5 cluster heads and a single stationary relay is considered as a case study. The relay location and its antenna height are optimized to achieve the line-of-sight connectivity over the whole mission duration. The antenna radiation pattern at the relay is incorporated in the analysis. The resulting star network topology is used by the cluster heads to broadcast their packets to all other cluster heads. Several relaying schemes including the amplify-and-forward and the decode-and-forward relaying are studied together with the go-back-N retransmissions to achieve the reliable data transfer

The national geomagnetic initiative

The Earth's magnetic field, through its variability over a spectrum of spatial and temporal scales, contains fundamental information on the solid Earth and geospace environment (the latter comprising the atmosphere, ionosphere, and magnetosphere). Integrated studies of the geomagnetic field have the potential to address a wide range of important processes in the deep mantle and core, asthenosphere, lithosphere, oceans, and the solar-terrestrial environment. These studies have direct applications to important societal problems, including resource assessment and exploration, natural hazard mitigation, safe navigation, and the maintenance and survivability of communications and power systems on the ground and in space. Studies of the Earth's magnetic field are supported by a variety of federal and state agencies as well as by private industry. Both basic and applied research is presently supported by several federal agencies, including the National Science Foundation (NSF), U.S. Geological Survey (USGS), U.S. Department of Energy (DOE), National Oceanic and Atmospheric Administration (NOAA), National Aeronautics and Space Administration (NASA), and U.S. Department of Defense (DOD) (through the Navy, Air Force, and Defense Mapping Agency). Although each agency has a unique, well-defined mission in geomagnetic studies, many areas of interest overlap. For example, NASA, the Navy, and USGS collaborate closely in the development of main field reference models. NASA, NSF, and the Air Force collaborate in space physics. These interagency linkages need to be strengthened. Over the past decade, new opportunities for fundamental advances in geomagnetic research have emerged as a result of three factors: well-posed, first-order scientific questions; increased interrelation of research activities dealing with geomagnetic phenomena; and recent developments in technology. These new opportunities can be exploited through a national geomagnetic initiative to define objectives and encourage coordination of efforts among federal and state agencies, academic institutions, and industry to systematically characterize the spatial and temporal behavior of the Earth's magnetic field on local, regional, and global scales in order to understand the physical processes in the solid earth and geospace environment, and to apply this understanding to a variety of scientific problems and to technical and societal needs

Still Dirty After All These Years: Political Leadership, Knowledge, and Socialization and Regional Environmental Cooperation in Northeast Asia

This dissertation examines the microprocesses of regime creation in Northeast Asia regarding transboundary environmental problems. Despite the growing need for international environmental cooperation and policy coordination at the regional and global levels, Northeast Asia has not yet succeeded in reaching any binding regional agreement on any environmental issue, even though it has developed various environmental cooperative mechanisms regarding transboundary pollution. Rather than characterizing regional environmental cooperative mechanisms in Northeast Asia as “non-regime,” this study unpacks the varying forms of collective action in terms of the speed of development of cooperative mechanisms and the substantive content of the development undertaken by states in the region. The causal relationships between specific forms of political leadership, knowledge, and socialization and the degrees and forms of regional collective action is explored regarding the transboundary air pollution issues of the region, including acid rain, dust and sandstorms, and various long-range transboundary air pollutants. In addition to comparing the participation of countries in this region in broader Northeast Asian cooperative mechanisms, the study also analyzes the differences between European and East Asian experiences on this topic. An analysis of the three cases indicates that all three independent variables areonly partly associated with varying degrees of collective action as measured by formal features and concrete collective action in Northeast Asia. The study’s comparison of the varying degrees of collective action in Northeast Asia and Europe and among the three studied Northeast Asian environmental cooperative mechanisms discovers two useful insights. First, the analysis supports the hypothesis on social mechanisms among political leadership, shared knowledge, and socialization, which asserts that the stronger the political leadership and the greater the shared knowledge in the region, the more likely participants in regional cooperation are to engage in the learning process of socialization and thereby create the most formal and concrete collective action. The study finds that st strong rong political leadership is not itself sufficient to lead member countries to engage in the learning process of socialization and that a lack of shared scientific knowledge is positively associated with the adaption process of socialization among participants in the cooperative activities of these three regional mechanisms. Another insight is that the lack of shared knowledge and of the learning mode of socialization helps explain why all three regional cooperative mechanisms have failed to advance to becomethe legally binding regional environmental regimes rather than the comparatively higher degrees of collective action in terms of formalization and concreteness among regional entities within the UNEP’s second category of regional action. This study argues that knowledge and socialization barriers are key determinants of the development of regulatory regional environmental regimes. Without shared scientific knowledge and engagement in the learning process of socialization, even given strong political leadership by a participating country, it is not likely for a region to develop a legally binding regional environmental regime.Therefore, this study concludes that to make the transformation from the least formal and concrete collective action to the most formal and concrete depends on creating shared knowledge and the learning process of socialization

The Digitalisation of African Agriculture Report 2018-2019

An inclusive, digitally-enabled agricultural transformation could help achieve meaningful livelihood improvements for Africa’s smallholder farmers and pastoralists. It could drive greater engagement in agriculture from women and youth and create employment opportunities along the value chain. At CTA we staked a claim on this power of digitalisation to more systematically transform agriculture early on. Digitalisation, focusing on not individual ICTs but the application of these technologies to entire value chains, is a theme that cuts across all of our work. In youth entrepreneurship, we are fostering a new breed of young ICT ‘agripreneurs’. In climate-smart agriculture multiple projects provide information that can help towards building resilience for smallholder farmers. And in women empowerment we are supporting digital platforms to drive greater inclusion for women entrepreneurs in agricultural value chains

Fighting the network: MANET management in support of littoral operations

Advances in computer processing and communications capabilities have contributed to the recent explosion of mesh network technologies. These technologies’ operational benefits are of particular interest for those operating in the littorals. The dynamic complexities of the littorals force tactical decision-makers to adapt to a constantly changing battlespace in a constrained temporal and spatial environment. Ongoing research into the integration of unmanned systems and sensors as mobile ad-hoc network (MANET) nodes highlights the significant potential to improve situational awareness and force efficiency in the littoral environment. However, difficulties associated with tactical network operations and management make the littorals particularly challenging. There remains a need for a unified approach to managing these networks in a coherent and effective manner. The complexity of the littorals emphasizes the inherent interconnectedness of MANET management and command and control (C2). As a result, new and innovative approaches to C2 are also required. This thesis explores the value of modern network management systems as they contribute to the richness of the human-network interface, as well as the integration of network management and maneuver at the tactical level. The result is a proposal for a novel framework for littoral MANET management and C2 as a corollary of cyber-physical maneuver.http://archive.org/details/fightingnetworkm1094548561Outstanding ThesisLieutenant, United States NavyApproved for public release; distribution is unlimited

Command and Control in the Information Age: A Case Study of a Representative Air Power Command and Control Node

As operations command structures change, it is important to be able to explore and understand their fundamental nature; researchers should unearth the gestalt nature of the operational node. The organizational structure and the infrastructure can significantly affect overall command and control (C2) performance. Thus, it is necessary to develop understanding of effectiveness of the technical network and the people using the system as a whole. The purpose of this research is to conduct an analysis of a representative Air Power Operational C2 node, create and use a repeatable method, and present the results as a case study to elicit fundamental understanding. I posit that there is a recognizable (and discoverable) relationship between the social (human) network and technical supporting network. Examining the system under change can result in an understanding of this relationship. In this work, I enhanced an existing simulation tool to investigate the effects of organizational structure on task effectiveness. The primary research question examined is how a representative AOC system changes varying noise and system fragmentation when operating in two different organizational constructs. Network-Enabled Capability (as the term is used in NATO), Network Centric Operations, or Edge Organizations, is a core C2 transformation predicated upon a set of network-centric tenets. These tenets form the intellectual foundation for ongoing transformations. The secondary research question is to determine if these tenets are unbound, and what elucidation results if they are not. This research produces four significant contributions to Operational Command and Control and Engineering Management disciplines. First, I combined social networking theory and information theory into a single lens for evaluation. By using this new concept, I will be able to accomplish a quantitative evaluation by something other than mission treads, field exercise, historical evaluation, or actual combat. Second, I used both information theory and social networking concepts in a non-traditional setting. Third, I hope this research will start the process required to gain the knowledge to achieve some sort of future C2 structure. Fourth, this research suggests directions for future research to enhance understanding of core Operational Command and Control concepts

Nature-based Interventions and the Environment-Microbiome-Health Axis

This interdisciplinary PhD is an innovative socioecological investigation into two key phenomena: 1. nature-based interventions, which are structured nature-based activities that aim to facilitate behavioural changes for the benefit of health and wellbeing; and 2. the relationship between the environment, the microbiome and human health. The aims of the PhD study include: o Determining the distribution of, and socioecological constraints and opportunities associated with nature-based interventions. o Ascertaining how engagement with nature may have supported population health during the COVID-19 pandemic, and whether the pandemic affected nature engagement. o Investigating the environment-microbiome-health axis, including a review of potential anthropogenic disruptions to this relationship, and determining the spatio-compositional and ecological factors that affect exposure to the aerobiome (microbiome of the air) in urban green spaces. o Determining whether relationships with and knowledge of biodiversity affect attitudes towards microbes. o The development of novel conceptualisations that transcend the boundaries of current knowledge, including Microbiome-Inspired Green Infrastructure (MIG) – multifunctional green infrastructure that aims to enhance ecosystem functionality and human health through considerations for the microbiome; the Lovebug Effect – microbially-mediated nature affinity; and, the Holobiont Blindspot – a newly proposed cognitive bias that may result from the failure to recognise the microbiome’s role in behaviour and health. This is a PhD by publication comprising 9 chapters and 12 publications. Chapter 2 presents publications on nature-based interventions (Robinson and Breed, 2019; Robinson et al. 2020a), and the potential health benefits of engaging with nature are presented in Chapter 3 (Robinson et al. 2020b). This is followed by an overview of the environment-microbiome-health axis (Robinson and Jorgensen, 2020) and how nature engagement may affect our attitudes towards microbes in Chapter 4 (Robinson et al. 2021e). This is followed by the aerobiome studies in Chapter 5 (Robinson et al. 2020c; Robinson et al. 2021b) and potential disruptions to the environmental microbiome and human health in Chapter 6 (Robinson et al. 2021c). Chapter 7 presents Microbiome-Inspired Green Infrastructure (Robinson et al. 2018; Watkins and Robinson et al. 2020), and finally in Chapter 8, novel conceptualisations are presented, including the Lovebug Effect (Robinson and Breed, 2020) and the Holobiont Blindspot (Robinson and Cameron, 2020). The methods used in the nature-based intervention studies included geospatial analysis using geographic information systems (GIS) and online questionnaires. The methods used in the microbiome studies included the creation of novel sampling methods to collect bacterial DNA in urban green spaces, DNA sequencing, and the application of bioinformatic tools. Although systematic reviews were not included, the reviews in this thesis did follow the preferred reporting system for systematic reviews (PRISMA) method to ensure robust data collection. This PhD makes several important contributions to knowledge. For example, constraints to nature-based interventions were identified, and these show that enhanced transdisciplinary collaborative pathways and efficient infrastructure are needed. The research also identified that people significantly changed their patterns of nature engagement during the COVID-19 pandemic and many visited nature for important wellbeing and coping benefits. This highlights the immense value of nature to health and wellbeing during unprecedented times. The research also revealed for the first time that attitudes towards microbes might be influenced by nature engagement and biodiversity literacy, and that anthropogenic pollution (light and sound) could affect the microbiome with important ecological and health implications. In the aerobiome studies, the cutting-edge discovery of ecological factors that drive aerobiome assembly and potentially affect exposure types and routes could have important implications for public health and landscape management. Nature-based interventions have the potential to enhance human and environmental health, and the environmental microbiome will likely play an important role. The novel conceptualisations developed during this PhD add new knowledge to the fields of landscape design, microbiome science, and environmental psychology and have stimulated new research agendas across the world. The work in this thesis is influenced by the emerging planetary health paradigm, the ‘interconnectedness’ and intrinsic value narrative associated with Indigenous cultures, and ‘systems thinking’ (a holistic analytical approach that focuses on the way a system’s constituent parts – – and how systems themselves –– interrelate). Fostering deep reciprocity with the natural world to enhance personal and planetary health has never been more important. We have a key opportunity to redefine our relationship with the wider biotic community by establishing a new appreciation of our ‘microbial friends’ and the profound interconnectedness between the environment, the microbiome and human health.

Holistic biomimicry: a biologically inspired approach to environmentally benign engineering

Humanity's activities increasingly threaten Earth's richness of life, of which mankind is a part. As part of the response, the environmentally conscious attempt to engineer products, processes and systems that interact harmoniously with the living world. Current environmental design guidance draws upon a wealth of experiences with the products of engineering that damaged humanity's environment. Efforts to create such guidelines inductively attempt to tease right action from examination of past mistakes. Unfortunately, avoidance of past errors cannot guarantee environmentally sustainable designs in the future. One needs to examine and understand an example of an environmentally sustainable, complex, multi-scale system to engineer designs with similar characteristics. This dissertation benchmarks and evaluates the efficacy of guidance from one such environmentally sustainable system resting at humanity's doorstep - the biosphere. Taking a holistic view of biomimicry, emulation of and inspiration by life, this work extracts overarching principles of life from academic life science literature using a sociological technique known as constant comparative method. It translates these principles into bio-inspired sustainable engineering guidelines. During this process, it identifies physically rooted measures and metrics that link guidelines to engineering applications. Qualitative validation for principles and guidelines takes the form of review by biology experts and comparison with existing environmentally benign design and manufacturing guidelines. Three select bio-inspired guidelines at three different organizational scales of engineering interest are quantitatively validated. Physical experiments with self-cleaning surfaces quantify the potential environmental benefits generated by applying the first, sub-product scale guideline. An interpretation of a metabolically rooted guideline applied at the product / organism organizational scale is shown to correlate with existing environmental metrics and predict a sustainability threshold. Finally, design of a carpet recycling network illustrates the quantitative environmental benefits one reaps by applying the third, multi-facility scale bio-inspired sustainability guideline. Taken as a whole, this work contributes (1) a set of biologically inspired sustainability principles for engineering, (2) a translation of these principles into measures applicable to design, (3) examples demonstrating a new, holistic form of biomimicry and (4) a deductive, novel approach to environmentally benign engineering. Life, the collection of processes that tamed and maintained themselves on planet Earth's once hostile surface, long ago confronted and solved the fundamental problems facing all organisms. Through this work, it is hoped that humanity has taken one small step toward self-mastery, thus drawing closer to a solution to the latest problem facing all organisms.Ph.D.Committee Chair: Bert Bras; Committee Member: David Rosen; Committee Member: Dayna Baumeister; Committee Member: Janet Allen; Committee Member: Jeannette Yen; Committee Member: Matthew Realf
