Chapters from modeling mortality in Hungary
… by cause of death, 3) investigation of the time-dependence of age-varying parameters, i.e., rotation and their incorporation into the prediction of some mortality models, and 4) application of tree-based machine learning methods to mortality projections. For these research topics, we fitted …

Evaluating multi-satellite chlorophyll-a datasets an ocean colour case study within the Southern Benguela
… multi-satellite products to create consistent long-term time-series datasets for climate studies at a global scale. Their ability to handle variable in-water conditions is critical for their mission parameters. This study compares the performance of two European multi-satellite chl-a products, …

Deep Learning Emulators for Accessible Climate Projections
… can make them more accessible and, at the same time, raise novel challenges in deep learning on physical, long-term time-series, and high-dimensional data. This dissertation shows that deep learning can decrease runtime in dynamical models, increase accuracy in local climate projections, and …

Atmospheric sub-10 nm aerosol number size distributions : measurement, analysis and implications
… is a major source of atmospheric aerosol in terms of number concentration. As the newly formed particles grow, they can affect climate both directly and indirectly. However, understanding the first steps of NPF is an ongoing challenge. This is challenging in terms of the complexity of the …

Media, Representation, Persistence and Relief: the Role of the Internet in Understanding the Physical and Social Dynamics of Catastrophic Natural Hazards.
… basis. The Internet allows for real-time communication and broadcasting of natural hazards information and provides an ever-growing archive of the temporal and spatial patterns within natural hazard event occurrence. Thus, an alternative technique of news media collation, using …

Quantitative Mapping of Cyanobacterial Blooms Using Oceansat-1 OCM Satellite Data
… field data are required to further validate the long-term performance of the algorithms, at present the algorithms may be implemented to process OCM data in an automated setup to provide timely information on the lake’s bloom conditions. Similarly, retrospective processing may provide a long-term …

The Influence of Changing Nutrients and Warming on Phytoplankton and its Interactions with Zooplankton in the North Sea
… and phytoplankton–zooplankton interactions using long-term satellite and in situ data. Satellite ocean-color analyses show predominantly declining Chl-a anomalies across the German Bight, with localized increases near the Elbe estuary. SST explains part of the long-term Chl-a variability, but …

Catchment scale modelling of micro and emerging pollutants
… in conjunction with the well-known travel time transport approach at the catchment-scale. In fact, with the travel time approach to pharmaceuticals represents a framework that allows dealing in a unitary and simple way the main two mitigation mechanisms controlling them, which are dilution …

Strategic Environmental Assessment for Municipal Water Demand Based on Climate Change
… variables drive water consumption in the short-term, and it enhances the accuracy of the prediction model when it is combined with socio-economic factors. However, the impact of climate change on the municipal water demand has yet to be challenged. To surmount this challenge, more research work …

Seismic precursor identification method integrating acoustic emission physical models and multi-source data
… the most challenging scientific problems of our time. Earthquakes result from macroscopic rock fracture in the Earth's crust, and their preparation process shares profound physical homology with the cross-scale damage evolution in materials, from microcrack initiation and propagation to …
