In this communication, hexapod tripod gaits for straightline motion and crab walking are derived. Mathematical relations that express the stability margin, the stride length, and the duty factor are formulated for straight-line motion and for crab walking, respectively. The derived results provide tripod gaits of the hexapod for walking with a prescribed stability margin either over perfect ter...

A vector surveillance trap support was designed as a tripod of polyvinyl chloride pipes to suspend carbon dioxide-baited traps. This system offers several advantages, including increased ease of transport and trap placement at varied sampling sites, particularly in adverse environments not conducive to previous methods of support. Presentation of the simple design and manufacture of the tripod ...

In 1984, S. K. Stein and his co-authors posed a problem concerning simple three-dimensional shapes, known as semicrosses, or tripods. By definition, a tripod is formed by a corner and the three adjacent edges of an integer cube. How densely can one fill the space with nonoverlapping tripods of a given size? In particular, is it possible to fill a constant fraction of the space as the tripod siz...

2014 A tripod field is used as model for a general anisotropic fluid. The elastic energy density is expanded as invariant polynomial in the components of the contortion tensor. Surface energy terms are derived from compatibility conditions for the tripod field. The model is applied to cholesteric liquid crystals of large and small pitch, to 3He-A, and to biaxial nematic liquid crystals. J. Phys...

BACKGROUND Patients who have undergone enucleation during infancy due to retinoblastoma can develop microorbitalism due to the decreased growth stimulation from the eyeball and the surrounding soft tissues. Anatomically, the orbit consist of parts of the frontal bone superiorly, the maxilla inferiorly, the ethmoid bone medially, and the zygoma laterally. Considering the possibility of surgicall...
