A new low order facet type triangular shell finite element is presented. The element is combined from the Arnold-Falk plate bending element and the membrane element based on the noncorming element of Crouzeix-Raviart with conforming drilling rotation. Formulation of the membrane element is based on the variational principle of Hughes and Brezzi employing independent rotation field. Interpolatio...

We show that a full element-index can be as space-efficient as a direct index with Dewey ids, after compression using typical techniques. 1 Full Element-Index for XML Keyword Search Keyword search is a crucial operation that has to be supported on XML data. Earlier works attacking this problem from information retrieval (IR) perspective essentially consider disjunctive query semantics (e.g., se...

In this paper, the linearly conforming enriched radial basis point interpolation method is implemented for the elasto-plastic analysis of discontinuous medium. The linear conformability of the method is satisfied by the application of stabilized nodal integration and the enrichment of radial basis functions is achieved by the addition of linear polynomial terms. To implement the method for the ...

BACKGROUND In some cases, it may be necessary to combine distinct finite element meshes into a single system. The present work describes a scheme for coupling a finite element mesh, which may have curvilinear elements, to a voxel based finite element mesh. METHODS The method is described with reference to a sample problem that involves combining a heart, which is defined by a curvilinear mesh...

Background: To explore a possible rela!onship among blood groups and the prognosis of breast cancer, this case- control study was carried out in Arak city, Arak province, Iran. Materials and Methods: One hundred and thirty four pa!ents with breast cancer were inves!gated. ABO blood groups were obtained from medical records. Mul!variate analyses were performed, including size of tumor, axilla...

Recent research has shown that using a mobile element to collect and carry data mechanically from a sensor network has many advantages over static multihop routing. We have an implementation as well employing a single mobile element. But the network scalability and traffic may make a single mobile element insufficient. In this paper we investigate the use of multiple mobile elements. In particu...

Stiffness matrix of the four-node quadrilateral plane stress element is decomposed into normal and shear components. A computer program is developed to obtain the straining modes using adequate and reduced integration. Then a solution for the problem of mixing straining modes is found. Accuracy of the computer program is validated by a closed-form stiffness matrix, derived for the plane rectang...
