幸福家庭六要素(Six elements of a happy family) What kind of family is happy? In my opinion, the first is to make all the family healthy. If there is one person in the family who is not healthy, at least it will affect the lives of fifty people. If parents are not healthy, we do...
finite element , fracture mechanics , composite materials , FINITE-ELEMENTS , INTERFACEA new finite element family which contains a lambda singularity is developed. Three elements are derived; namely three-, four- and five-noded elements which are compatible with linear, quadratic and cubic standard...
We propose two families of mixed finite elements to solve the discrete problem, in the first family, the unknowns are approximated by piecewise continuous... V Anaya,D Mora,R Ruiz-Baier - 《Computer Methods in Applied Mechanics & Engineering》 被引量: 11发表: 2013年 Novel analysis approach ...
A physical technique known as two-dimensional S1 nuclease heteroduplex mapping has been applied to genomic DNA from the Gram-negative coccus Neisseria gonorrhoeae. This has resulted in the detection of two novel types of repetitive sequences. The first type is a repetitive sequence family of 152...

Short interspersed repetitive elements (SINEs) have been shown to be excellent markers of molecular phylogeny, since the integration of a SINE at a particular position in a genome can be considered an unambiguous derived homologous character. In the present study, we isolated a new family of SINEs...

We present a family of mixed finite element spaces for second order elliptic equations in two and three space dimensions. Our spaces approximate the vector flux by a continuous function. Our spaces generalize certain spaces used for approximation of Stokes problems. The finite element method incorpora...
