By adopting the variational point of view, the constitutive equations of a non linear elastic plate are deduced under kinematical constraints on the admissible deformations.

short-selling prohibition has been one of the primary assumptions of markowitz mean-variance model. solving markowitz quadratic model creates investment efficient frontier by considering only two return and budget constraints. in order to develop a more realistic portfolio selection model, in this paper, a new mathematical model is developed to allow short-selling under some practical constrain...

In this paper, we theoretically address three fundamental problems involving deep convolutional networks regarding invariance, depth and hierarchy. We introduce the paradigm of Transformation Networks (TN) which are a direct generalization of Convolutional Networks (ConvNets). Theoretically, we show that TNs (and thereby ConvNets) are can be invariant to non-linear transformations of the input ...

This work is devoted to the formulation and derivation of the α−κ−μ/gamma distribution which corresponds to a physical fading model. The proposed distribution is composite and is constituted by the α−κ−μ non-linear generalized multipath model and the gamma shadowing model. It also constitute the basis for deriving the α−κ−μ Extreme/gamma model which accounts for non-linear severe multipath and ...

Semiparametric time series regression is often used without checking its suitability, resulting in an unnecessarily complicated model. In practice, one may encounter computational difficulties caused by the curse of dimensionality. The paper suggests that to provide more precise predictions we need to choose the most significant regressors for both the parametric and the nonparametric time seri...

This paper attempts to theoretically understand the process of catching-up or falling behind particularly within the context of developing countries. The main aim of the paper consists in investigating the impact of domestic innovation, via its interaction with the learning capability, on the technology gap of an economy. More specifically, we seek to shed some light on why the tendency for poo...

background and aim: it has been several decades since the technology of frequency lowering (fl) has been proposed. however, primary research has revealed no benefits regarding the use of this technique. currently, new methods for fl and improvement of perception of speech and fricative sounds have led to the application of these methods by numerous companies to produce hearing aids. in this stu...

The process of sexual response is defined in four phases: Desire, Excitement or arousal, Orgasm and Resolution. This model was introduced by Mr. Masters and Mrs. Johnsons for the first time and then completed by Mrs. Kaplan. At that time, this classification was so practical and valuable for understanding sexual response and thereupon defining sexual dysfunctions, even being still used as a cri...
