Visual cues play important roles in sea turtle foraging behavior and likely influence their interactions with fishing gear. Altering these cues may be a useful strategy to reduce the incidental catch of sea turtles in various fisheries. We examined the potential effectiveness of 3 visual cues — shark shapes placed along the length of the gill net, illumination of nets by LED lights, and nets il...

This paper explored how sensation seeking contributes to the likelihood of tanning bed use intentions both directly and indirectly through the way it shapes interaction with peers who use tanning beds and attitudes toward tanning bed. Eight hundred and ninety six (n = 896) male and female college students were recruited for the study. Measured variables included sensation seeking, association w...

[1] We investigate the stability of marine ice sheets by coupling a gravitationally self-consistent sea level model valid for a self-gravitating, viscoelastically deforming Earth to a 1-D marine ice sheet-shelf model. The evolution of the coupled model is explored for a suite of simulations in which we vary the bed slope and the forcing that initiates retreat. We find that the sea level fall at...

The sleep system (i.e. the combination of mattress and bed base) is an important factor of the sleep environment since it allows physical recuperation during sleep by providing proper body support. However, various factors influence the interaction between the human body and the sleep system. Contributing factors include body dimensions, distribution of body weight and stiffness of the sleep sy...

In dynamic analysis of floating structures, the designer needs to know the wave forces due to incident and scattered waves on the structure. In this work, the flow field around the body is solved based on the potential theory with considering the free surface and sea bed effects. Using this theory, the wave forces exerted on two typical sea buoys with spherical and disc-type bodies are determin...

We present a reactive navigation algorithm for safe operation of hospital beds in dynamic environments. The proposed navigation is implementation efficient in the sense that it does not require any measurements from the velocities, shapes, dimensions or orientations of the obstacles. Furthermore, it is applicable for a variety of real world scenario where the natures and the motions of the obst...

Shifts from productive kelp beds to impoverished sea urchin barrens occur globally and represent a wholesale change to the ecology of sub-tidal temperate reefs. Although the theory of shifts between alternative stable states is well advanced, there are few field studies detailing the dynamics of these kinds of transitions. In this study, sea urchin herbivory (a 'top-down' driver of ecosystems) ...

We review electromagnetic interferometry by multidimensional deconvolution (MDD) and investigate its sensitivity to spatial sampling. Two Sea Bed Logging datasets were modeled numerically. One represents a shallow sea situation with a small vertical source-receiver distance and the other a deep sea situation with a large vertical source-receiver distance. The reflection response from below the ...
