The response of the water table of an intertidal salt marsh in NW England has been investigated. During neap tides, water seeps upward from the underlying sand-silt-clay interface. This effect continues as the marsh is overtopped during spring tides but is then dwarfed by penetration of water downward from the surface. Under “typical conditions” the delay between high water in the river and max...

MIDDLE EAST JOURNAL ✮ VOLUME 58, NO. 2, SPRING 2004 Dhufar, the southern region of the Sultanate of Oman, displays a tremendous diversity in its social structure, rather surprising for an area so small. While the people of the coastal plain and the inland Najd are Arabic-speaking, the mountain highlands of the region are home to various non-Arabic speaking communities. Brief descriptions of the...

We analyze a simple model for running: a three-dimensional springloaded inverted pendulum carrying a point mass (3D-SLIP). Our formulation reduces to the sagittal plane SLIP and horizontal plane lateral leg spring (LLS) models in the appropriate limits. Using the intrinsic geometry and symmetries and appealing to the case of stiff springs, in which gravity may be neglected during stance, we der...

Many of Florida’s springs and spring runs are enriched in nitrate due to broad-scale contamination of groundwater supplies. This observation fosters two primary and interrelated concerns regarding the effects of nutrients on flora and fauna in spring systems. High nitrate concentrations can affect fauna directly through toxicity. In addition, high nitrate concentrations can promote eutrophicati...

We propose an integrated facial dynamics model addressing the animation of 3D humanoid faces in real time. The computational model mimics facial motion by reproducing the layered anatomical structure of a human head including the bony structure, overlapping facial muscles and the skin. The model is flexible enough to animate face meshes of various shape, connectivity, and scale. Different from ...

Robust and energy-efficient bipedal locomotion in robotics is still a challenging topic. In order to address issues in this field, we can take inspiration from nature, by studying human locomotion. The Spring-Loaded Inverted Pendulum (SLIP) model has shown to be a good model for this purpose. However, the human musculoskeletal system enables us to actively modulate leg stiffness, for example wh...

All of us at the SMC office hope you had a wonderful holiday season. This Fall has been busy as usual with field work that is actually a bit ahead of schedule. Be sure to note the date and location of our Spring Meeting and the First International Precision Forestry Symposium in the Conferences and Meeting Section. An announcement with registration and program details will be mailed in early 20...

In this paper, we report on a new stability analysis for hybrid legged locomotion systems based on factorization of return maps. We apply this analysis to a family of models of the Spring Loaded Inverted Pendulum (SLIP) with different leg recirculation strategies. We obtain a necessary condition for the asymptotic stability of those models, which is formulated as an exact algebraic expression d...

Global warming has shifted the onset of spring plant phenology towards earlier dates. This shift can lead to “false springs” (plants get frost damage) because the date of last frost has not advanced at the same pace than the advancement of spring onset. Here, we use a cloud computing approach for processing big and high spatial resolution grids of temperature data to map the occurrence of false...
