  2. 1. Environmental-flow assessments for current and future run-off in a large river system regulated for hydropower production

    Author : Åsa Widén; Roland Jansson; Birgitta Malm-Renöfält; Michael McClain; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental flows; eco-hydrology; hydropower; river ecosystem; environmental benefits; climate change; collaboration; resource management; Ekologisk reglering; vattenkraft; produktionsoptimering; hydrologi; hydraulik; akvatiskt ekosystem; miljönytta; klimatförändringar; samverkan; vattenresurs management;

    Abstract : In 2019, Sweden implemented legislative changes to renegotiate hydropower permits to both consider environmental rehabilitation and to ensure national supply of hydropower. This means that efforts for environmental rehabilitation of the 2,000 hydropower plants in Sweden need to be considered. READ MORE

  4. 2. Towards Precise Localisation : Subsample Methods, Efficient Estimation and Merging of Maps

    Author : Gabrielle Flood; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; localisation; map merging; subsample; stochastic analysis; time-difference-of-arrival;

    Abstract : Over the last couple of years audio and radio sensors have become cheaper and more common in our everyday life. Such sensors can be used to form a network, from which one can obtain distance measures by correlating the different received signals. READ MORE

  5. 3. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations

    Author : Gabrielle Flood; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time of arrival; TOA; Time-difference of arrival; TDOA; Subsample methods; Uncertainty measure; Constant offset; RANSAC; Map merging; Map fusion; Change detection; Collaborative SLAM; Structure from motion; SfM; SLAM; Mapping; Localisation; Registration; Sparse maps; Point clouds;

    Abstract : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. READ MORE

  6. 4. Flood Prediction in data-scarce basins : Maximising the value of limited hydro-meteorological data

    Author : José Eduardo Reynolds Puga; Sven Halldin; Chong-Yu Xu; Jan Seibert; Thomas J. Grabs; Vazken Andréassian; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Floods; data scarcity; value of information; rainfall-runoff modelling; regionalisation; rainfall-forecasts; event-based calibration; climatological day; discharge day; temporal resolution; modelling time-step.; Databrist; flödestoppsbaserad kalibrering; högflöde; informationsvärde; klimatologiskt dygn; nederbörds-avrinningsmodell; modelltidssteg; regionalisering; regnprognos; tids-upplösning; vattenföringsdygn; översvämning.; Inundaciones; falta de datos; valor de información; modelos lluvia escorrentía; regionalización; pronósticos de lluvia; definición del día; resolución temporal; paso de tiempo.;

    Abstract : Floods pose a threat to society that can cause large socio-economic damages and loss of life in many parts of the world. Flood-forecasting models are required to provide simulations at temporal resolutions higher than a day in basins with concentration times smaller than 24 h. READ MORE

  7. 5. Anxiety and (In)Security in Times of Calamity : The 2014 flood and the Kashmir conflict

    Author : Rasmus Andrén; Eva-Karin Olsson Gardell; Simon Hollis; Scott Watson; Försvarshögskolan; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Disaster; Conflict; Disruption; Anxiety; Ontological Security; Kashmir; Katastrof; konflikt; störning; ångest; ontologisk säkerhet; Kashmir; Political Science; Statsvetenskap;

    Abstract : Environmental calamities and disasters are increasingly found to affect political stability and conflicts. Despite a plethora of research across a range of disciplines, however, explanations remain elusive. READ MORE
