data. Although there were some differences they concluded: “Because onset and end dates of the growing season were averaged over the entire Tibetan Plateau, the temporal resolution of the data was deemed sufficiently high for detailed analysis.” So they tested whether winter warming might affect the plants’ chilling requirements in this cold, highaltitude environment. They determined the beginn...

In this paper, we present our implementation of physically-based simulation of hair strips. We used a mass-spring model followed by a hybrid approach where particle systems and the method of clustering of hair strands are employed. All the forces related to springs are implemented: gravity, repulsions from collisions (head and ground), absorption (ground only), frictions (ground and air), inter...

The spring pendulum in resonance is a model system for formal reduction to one degree of freedom, where some symmetry (reversibility) is maintained. The reduction can be handled by equivariant singularity theory with a distinguished parameter, yielding an integrable approximation of the Poincar e map. This makes a concise description of certain bifurcations possible. The computation of reparame...

Digital watermarking techniques have been proposed to protect the copyright of multimedia data. Robustness against geometric distortion is one of the most important issues to be solved to increase the robustness of digital image watermarking systems. Such attacks are very simple to implement, so they can defeat most existing watermarking algorithms without causing serious perceptual distortion....

According to a company developed twelve meters bus, using the multi-body dynamics software ADAMS, they reached the conclusion that the change scope of the toe angle, and camber in the guide mechanism with wheel vertical, affects the operation stability. Utilizing: i) the air suspension guide mechanism of spatial position as design variables, ii) the front wheel alignment parameters as the objec...

The bivalve Macoma balthica migrates twice during the benthic part of its life cycle. During the spring migration (May–June), the newly settled spat (0-group) migrates to the nurseries in the high intertidal. Seven to nine months later, the bivalves migrate back to the low tidal flats and the subtidal (winter migration, 1-group). Both 0and 1-group M. balthica use byssus threads for active pelag...

This work presents a segmentation method based on a region growing approach. It has been implemented in the geographic information and image processing system (SPRING) which has been developed at INPE. The technique is applied to segment images which are being used to assess land use changes in the Amazon region. Segmented Landsat-TM images are shown to illustrate the technique.

The articles on weather and asthma focused on outbreaks of asthma flare-ups during periods of thunderstorms, especially in the late spring and early summer. These studies, conducted in Australia and Great Britain, did seem to find a correlation between spring storms and increased problems with asthma. Researchers speculate the phenomenon may have two possible causes. The most likely is related ...

Creep performance of zinc borate-treated strandboard from southern pine (Pinus taeda L.) and red oak (Quercus falcata) was investigated at 25°C temperature and 65% relative humidity. It was shown that the borate treatment had some signifi cant effect on creep defl ection of the test panels, and the effect varied with wood species. There was no signifi cant effect of creep loading on residual be...

In the framework of Geoland, Infoterra France has mapped with MERIS the distribution of annual crops surfaces in Belgium, Poland and Russia (Rostov oblast). The maps provided are the acreages of main groups of crops per administrative or agricultural circumscriptions unit. The groups are winter, spring and root crops (sugar beet, potatoes). The method for mapping exploits the MERIS capability t...
