The paper presents the results of the physicochemical parameters of the springs of Andros which were studied to evaluate the chemistry of the major ions and solute acquisition processes, which control the chemical composition and the suitability of the quality of water for drinking use. Forty two samples were taken for physicochemical analysis almost at the end of the summer period, in September 2014. The Piper plot was used for the hydrogeochemical classification of groundwater which also indicated that the majority of groundwater samples belong to the Ca-Na-HCO3-Cl type. According to the Durov plot the majority of samples, can be positioned in field 2 in which a process of cation exchange is in progress. Also, the HCO3 /(HCO3 +SO4) ratio indicates a weathering process from carbonic acid. In general, the majority of samples can be characterized as potable.

Land Question

This book takes a fresh look at the land question in India. It goes beyond re-engagement in the rich transition debate by critically examining both theoretically and empirically the role of land in contemporary India. Springing from the political economy discourse surrounding the classic capitalist transition issue in agriculture in India, the book gravitates toward the development discourse that inevitably veers toward land and the role of the state in pushing a process of dispossession of peasants through direct expropriation for developmental purposes. Contemporary dispossession may look similar to the historical process of primitive accumulation that makes room for capitalist agriculture and expanded accumulation. But this volume shows that land in India is sought increasingly for non-agricultural purposes as well. These include risk mitigation by farmers, real estate development, infrastructure development by states often on behalf of business, and special economic zones. Tribal communities (advasis), who depend on land for their livelihoods and a moral economy that is independent of any price-driven markets, hold on to land for collective security. Thus land acquisition continues to be a turbulent arena in which classes, castes, and communities are in conflict with the state and capital, each jockeying to determine the terms and conditions of land transactions or their prevention, through both market and non-market mechanisms. The volume collectively addresses the role of the state involved in the process of dispossession of peasants and tribal communities. It provides new analytical insights into the land acquisition processes, their legal-institutional and ethical implications, and captures empirically the multifaceted regional diversity of the contestations surrounding the acquisition experiences in India.

Aims: Future research on health inequality relies on data that cover life-course exposure, different birth cohorts and variation in policy contexts. Nordic register data have long been celebrated as a ‘gold mine’ for research, and fulfil many of these criteria. However, access to and use of such data are hampered by a number of hurdles and bottlenecks. We present and discuss the experiences of an ongoing Nordic consortium from the process of acquiring register data on socio-economic conditions and health in Denmark, Finland, Norway and Sweden. Methods: We compare experiences of data-acquisition processes from a researcher’s perspective in the four countries and discuss the comparability of register data and the modes of collaboration available to researchers, given the prevailing ethical and legal restrictions. Results: The application processes we experienced were time-consuming, and decision structures were often fragmented. We found substantial variation between the countries in terms of processing times, costs and the administrative burden of the researcher. Concerned agencies differed in policy and practice which influenced both how and when data were delivered. These discrepancies present a challenge to comparative research. Conclusions: We conclude that there are few signs of harmonisation, as called for by previous policy documents and research papers. Ethical vetting needs to be centralised both within and between countries in order to improve data access. Institutional factors that seem to facilitate access to register data at the national level include single storage environments for health and social data, simplified ethical vetting and user guidance.

AbstractThis paper addresses the problem of efficient and effective data collection and analytics for applications such as civil infrastructure monitoring and emergency management. Such problem requires the development of techniques by which data acquisition devices, such as IoT devices, can: (a) perform local analysis of collected data; and (b) based on the results of such analysis, autonomously decide further data acquisition. The ability to perform local analysis is critical in order to reduce the transmission costs and latency as the results of an analysis are usually smaller in size than the original data. As an example, in case of strict real-time requirements, the analysis results can be transmitted in real-time, whereas the actual collected data can be uploaded later on. The ability to autonomously decide about further data acquisition enhances scalability and reduces the need of real-time human involvement in data acquisition processes, especially in contexts with critical real-time requirements. The paper focuses on deep neural networks and discusses techniques for supporting transfer learning and pruning, so to reduce the times for training the networks and the size of the networks for deployment at IoT devices. We also discuss approaches based on machine learning reinforcement techniques enhancing the autonomy of IoT devices.

Submarine inspections and surveys require underwater vehicles to operate in deep waters efficiently, safely and reliably. Autonomous Underwater Vehicles employing advanced navigation and control systems present several advantages. Robust control algorithms and novel improvements in positioning and navigation are needed to optimize underwater operations. This paper proposes a new general formulation of this problem together with a basic approach for the management of deep underwater operations. This approach considers the field of view and the operational requirements as a fundamental input in the development of the trajectory in the autonomous guidance system. The constraints and involved variables are also defined, providing more accurate modelling compared with traditional formulations of the positioning system. Different case studies are presented based on commercial underwater cameras/sonars, analysing the influence of the main variables in the measurement process to obtain optimal resolution results. The application of this approach in autonomous underwater operations ensures suitable data acquisition processes according to the payload installed onboard.
