Based on a series of physical model tests and numerical simulations, the bearing characteristics tripod-bucket foundation are investigated. It is found that with decrease in aspect ratio (L/D), rotation center will decrease, displacement change from to uplift. Characteristics earth pressure buckets both finite element analysis studied, which used explain failure mechanism for foundations differ...

The tripod operator is a class of feature extraction operators for range images which facilitate the recognition and localization of objects. It consists of three points in 3-space fixed at the vertices of an equilateral triangle and a procedure for making several scalar measurements in the coordinate frame of the triangle. The triangle is then moved as a rigid body until the three vertices lie...

The tripod (ding 鼎) and the nine tripods (jiuding 九鼎) are significant in ancient China, appearing often Daoist alchemy. However, they have been largely ignored by scholarship on Daoism. Early alchemy saw as critical elements production of immortality, but outer (waidan 外丹) gave up refining elixir due to technical reasons. was merely mentioned elaboration Later, Southern Song dynasty, inner (nei...

We describe for the first time, the synthesis and some bioconjugation applications of an original heterotrifunctional cross-linking reagent (also named tripod) bearing three different bioorthogonal functional groups which are fully compatible amongst themselves. Contrary to the first generation tripod recently reported by us (Org. Biomol. Chem., 2008, 6, 3065), the use of an azido group instead...
