Abstract Climate change and human activities influence the development of ecosystems, with demand ecosystem services altering both land use cover. Fossil pollen records provide time series vegetation characteristics, aim this study was to create spatially continuous reconstructions cover through Holocene in southern Sweden. The Landscape Reconstruction Algorithm (LRA) applied obtain quantitativ...

Modeling and inferring spatial relationships predicting missing values of environmental data are some the main tasks geospatial statisticians. These routine accomplished using multivariate models cokriging technique. The latter requires evaluation expensive Gaussian log-likelihood function, which has impeded adoption for large datasets. However, this large-scale challenge provides a fertile gro...

Temperature is the most used meteorological variable for a large number of applications in urban resilience planning, but direct measurements using traditional sensors are not affordable at usually required spatial density. On other hand, spaceborne remote sensing provides surface temperatures medium to high resolutions, almost compatible with needed requirements. However, this case, limitation...

The role of natural background radiation (NBR) in childhood acute leukemia (AL) remains unclear. Several large record based studies have recently reported heterogeneous results. Differences exposure assessment timing may explain this heterogeneity. In a previous ecological study we did not observe any association between AL incidence France and NBR at the time diagnosis. With same methodology, ...

Due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. The known world class Cu-Mo deposit, Sarcheshmeh Porphyry deposit (central Iran) selected as the study area. The Hypogene zone of the deposit was chosen as the space in which estim...

This paper deals with aerodynamic shape optimization using an high fidelity solver. Due to the computational cost and restitution time needed to solve the RANS equations, this type of optimization framework must improve the solution using very few objective function evaluations despite the high number of design variables. The choice of the optimizer is thus largely based on its speed of converg...

extended abstract   introduction the most important indicator of climate in a region is vegetation community. climate can be different over large areas, because of changes in vegetation community. vegetation influences weather and climate in its surrounding areas mostly by way of evapotranspiration and albedo so they play a role in the earth’s energy balance. these effects on the earth’s energy...

Bamboo forests are widespread in subtropical areas and well known for their rapid growth great carbon sequestration ability. To recognize the potential roles functions of bamboo regional ecosystems, forest aboveground biomass (AGB)—which is closely related to productivity, cycle, and, particular, sinks ecosystems—is calculated applied as an indicator. Among existing studies considering AGB esti...
