a new approach for analyzing cracked problems in 2d orthotropic materials using the well-known element free galerkin method and orthotropic enrichment functions is proposed. the element free galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. in this study, element free galerkin is extrinsically enriched by the recently developed crack-tip orthot...

row/column have eigenvalues with absolute value strictly less than λmax = ρA. Informally, this says: ρA increases when any entry of A increases. 3. That eigenvalue ρA has algebraic and geometric multiplicity equal to one. 4. If y ≥ 0, y 6= 0 is a vector and μ is a number such that Ay ≤ μy, then y > 0 and μ ≥ λmax; with μ = λmax iff y is a multiple of x. Informally, this says: there is no other ...

Abstract We prove some important properties of the extremal coefficients a stable tail dependence function (“STDF”) and characterise logistic related STDFs. The well known sufficient conditions for composebility STDFs are shown to be also necessary.

In this study, a simple 4-node locking-alleviated mixed finite element (denoted as CEQ4) is developed, for the modeling of homogeneous or functionally graded or laminated thick-section composite beam structures, without using higher-order (in the thickness direction) or layer-wise zig-zag theories of composite laminates which are widely popularized in current literature. Following the work of [...

This paper deals with the calculation of full-field displacement over a surface of metallic foam. Owing to the failure of traditional displacement measurement method which calculates the correlation of intensity pattern between two regions, we propose a cellular based full field displacement calculation. The nodes are extracted from the cell boundary and nodal displacement is found by a thin pl...

This research was conducted to optimize the distribution system using Adaptive Neuro Fuzzy Inference System (ANFIS) method. Objective functions used are to minimize active power loss, node voltage deviation, number of switches, and maintain balance of the feeder. This function is modeled in a fuzzy set to build basic characteristics. The Method has been applied to the 32 bus IEEE standard distr...

background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...
