This work discusses the accuracies of geophysical model functions (GMFs) for retrieval of sea surface wind speed from satellite-borne Synthetic Aperture Radar (SAR) images in Japanese coastal waters characterized by short fetches and variable atmospheric stability conditions. In situ observations from two validation sites, Hiratsuka and Shirahama, are used(More)
Offshore wind resource maps for the coastal waters off Shirahama, Japan were made based on 104 images of the Advanced Synthetic Aperture Radar (ASAR) onboard the ENVISAT satellite. Wind speed fields were derived from the SAR images with the geophysical model function CMOD5.N. Mean wind speed and energy density were estimated using the Weibull distribution(More)
Evaporation residue cross sections in the 16O+238U reaction were measured for the energy range from above- to extreme sub-barrier. The cross sections are reproduced by a statistical model calculation, for which partial cross sections are calculated by a coupled-channel model taking into account the prolate deformation of 238U. Complete fusion was observed(More)
Vanadium K-edge XAFS measurements of five compounds were carried out. The compounds studied were crystalline V(2)O(5) and four types of Li(x)V(2)O(5) with different insertion levels x, which show different EMFs (2.0-3.4 V). The EXAFS data analysis shows no remarkable difference in the V-O distances in the five compounds, showing that the structure of the(More)
