The effect of recency to human mobility

Publication ID: pub.1052282068

Publication date: 17/12/2015

Keywords: Brazil; Global; Human Mobility; Mobility Data Analysis; Regularities in Human Dynamics

In recent years, we have seen scientists attempt to model and explain human dynamics and in particular human movement. Many aspects of our complex life are affected by human movement such as disease spread and epidemics modeling, city planning, wireless network development, and disaster relief, to name a few. Given the myriad of applications, it […]

Attribution of extreme weather and climate‐related events

Publication ID: pub.1022075093

Publication date: 16/12/2015

Keywords: Anthropogenic Climate Change; Assessments; Event Attribution; Extreme and Climate-related Events; Global; Human Influence; Magnitude; Natural Climate Variability; Probability; Science

Extreme weather and climate-related events occur in a particular place, by definition, infrequently. It is therefore challenging to detect systematic changes in their occurrence given the relative shortness of observational records. However, there is a clear interest from outside the climate science community in the extent to which recent damaging extreme events can be linked […]

Links between tropical Pacific seasonal, interannual and orbital variability during the Holocene

Publication ID: pub.1013686028

Publication date: 14/12/2015

Keywords: Climate Models; Coral and Mollusc Records; El Niño/Southern Oscillation (ENSO); Holocene; Line Islands; New Caledonia; Orbital Forcing; Pacific Region; Papua New Guinea; Tropical Pacific; Variability

The El Niño/Southern Oscillation (ENSO) is the leading mode of interannual climate variability. However, it is unclear how ENSO has responded to external forcing, particularly orbitally induced changes in the amplitude of the seasonal cycle during the Holocene. Here we present a reconstruction of seasonal and interannual surface conditions in the tropical Pacific Ocean from a […]

The long-term fate of permafrost peatlands under rapid climate warming

Publication ID: pub.1038190801

Publication date: 09/12/2015

Keywords: Abisko; Carbon Store; Climate-feedback Mechanisms; Climate Warming; Hydrology; Methane Emissions; Peat Accumulation; Permafrost Peatlands; Permafrost Thaw; Response; Soil Organic Carbon; Sweden; Vegetation

Permafrost peatlands contain globally important amounts of soil organic carbon, owing to cold conditions which suppress anaerobic decomposition. However, climate warming and permafrost thaw threaten the stability of this carbon store. The ultimate fate of permafrost peatlands and their carbon stores is unclear because of complex feedbacks between peat accumulation, hydrology and vegetation. Field monitoring […]

A framework for estimating forest disturbance intensity from successive remotely sensed biomass maps: moving beyond average biomass loss estimates

Publication ID: pub.1022924282

Publication date: 02/12/2015

Keywords: Biomass; Carbon; Deforestation; Degradation; Disturbance; Forest; Intensity; Mozambique; REDD; Remote Sensing; Satellite; Sofala

Background The success of satellites in mapping deforestation has been invaluable for improving our understanding of the impacts and nature of land cover change and carbon balance. However, current satellite approaches struggle to quantify the intensity of forest disturbance, i.e. whether the average rate of biomass loss for a region arises from heavy disturbance focused […]

Modelling and simulation of operation and maintenance strategy for offshore wind farms based on multi-agent system

Publication ID: pub.1048930130

Publication date: 30/11/2015

Keywords: Failure Modes; Global; Maintenance; Multi-agent Systems; Offshore Wind Turbine; Renewable Energy; Simulation

Maintenance of offshore wind turbines is a complex and costly undertaking which acts as a barrier to the development of this source of energy. Factors such as the size of the turbines, the size of the wind farms, their distance from the coast and meteorological conditions make it difficult for the stakeholders to select the […]
