ICE is a new incremental construction algorithm of a hybrid system for continuous learning tasks. The basis of the hybrid system is a radial basis function (RBF) network layer. The second layer consists of local models. The two layers are closely combined with a strong interaction. For example information from the model-layer is used by the RBF-layer to decide if new RBF-neurons are needed and ...

[1] Several continuous observational datasets of Artic seaice concentration are currently available that cover the period since the advent of routine satellite observations. We report on a comparison of three sea-ice concentration datasets. These are the National Ice Center charts, and two passive microwave radiometer datasets derived using different approaches: the NASA team and Bootstrap algo...

The offshore wind industry is growing at high pace and is already one of the major renewable energy sources in Europe. To support this growth, costs must be further decreased, amongst others by efficiently designing the support structure of the offshore wind turbines. This requires accurate prediction of environmental loading such as dynamic ice-structure interaction. From industry practice it ...

The large (7 m×4 m cylinder, 84 m3) AIDA (Aerosol Interactions and Dynamics in the Atmosphere) cloud chamber facility at Forschungszentrum, Karlsruhe, Germany was used to test the ice nucleating ability of two desert dust samples from the Sahara and Asia. Aerosol samples were lognormally distributed with a mode diameter of 0.4(±0.1)μm and geometric standard deviation of ∼1.7(±0.2). At temperatu...

SCIENCE Geological History In past discussions and speculations concerning the early peopling of the New World, the hypothesized "migration cor-ridor" between the Cordilleran and Lau-rentian ice sheets has figured prominently (1). By contrast with this much-mooted route east of the Rocky Mountains , little consideration has been given to possible routes west of the Rockies. I will examine such ...

A controlled experiment was conducted at the Cold Region Research and Engineering Laboratory (CRREL) facilities for retrieving freshwater ice characteristics using a Frequency Modulated Continuous Wave (FM-CW) radar system. The objectives of the experiment are 1) to try to unravel the complex interactions between a backscattered radar signal and ice cover characteristics such as thickness and a...

Of the modern technologies in polar-region monitoring, the remote sensing technology that can instantaneously form large-scale images has become much more important in helping acquire parameters such as the freezing and melting of ice as well as the surface temperature, which can be used in the research of global climate change, Antarctic ice sheet responses, and cap formation and evolution. Ho...
