A Super - Element Based on Finite Element Method for Latticed Columns Computational Aspect and Numerical Results
This paper presents a new super-element with twelve degrees of freedom for latticed columns. This elements is developed such that it behaves, with an acceptable approximation, in the same manner as a reference model does. The reference model is constructed by using many Solid elements. The cross section area, moments of inertia, shear coefficient and torsoinal rigidity of the developed new elem...
متن کاملA Sign Preserving Mixed Finite Element Approximation for Contact Problems
This paper is concerned with the frictionless unilateral contact problem (i.e., a Signorini problem with the elasticity operator). We consider a mixed finite element method in which the unknowns are the displacement field and the contact pressure. The particularity of the method is that it furnishes a normal displacement field and a contact pressure satisfying the sign conditions of the continu...
متن کاملBeware of Chilaiditi sign!!
A 41-year-old male with a history of Down’s syndrome, seizure disorder, renal calculi, and chronic respiratory failure was admitted for complicated urinary tract infection. Chest X-ray (Fig. 1) showed elevated right hemidiaphragm. CT abdomen (red arrows Figs. 2 and 3) demonstrated interposition of colon between right hemidiaphragm and liver (Chilaiditi sign) as well as gallstones. Chilaiditi si...

متن کاملThere may be no nowhere dense ultrafilter
We show the consistency of ZFC + ”there is no NWD-ultrafilter on ω”, which means: for every non-principal ultrafilter D on the set of natural numbers, there is a function f from the set of natural numbers to the reals, such that for every nowhere dense set A of reals, {n : f(n) ∈ A} / ∈ D. This answers a question of van Douwen, which was put in more general context by Baumgartner. ∗ The researc...
