We present here a complete description of the quantization of the baker’s map. The method we use is quite different from that used in Balazs and Voros [BV] and Saraceno [S]. We use as the quantum algebra of observables the operators generated by {exp (2πix̂) , exp (2πip̂)} and construct a unitary propagator such that as ~ → 0, the classical dynamics is returned. For Planck’s constant h = 1/N , we...

We show how to do efficient moment based inference using the generalized method of moments (GMM) when data is collected by standard stratified sampling and the maintained assumption is that the aggregate shares are known.

This study aims to explore how environmental, social and governance (ESG) consistency impacts the firm performance, specifically, the relationship between ESG performance and economic performance (EP). This study posits that the company’s commitment and effectiveness towards the creation of consistent competitive advantage in environmental, social and governance dimensions constitutes an intang...

This paper describes a computational procedure which is being developed for the practical analysis of propeller sheet cavitation and propeller-ship interaction including hull pressure fluctuations. The computational procedure consists of three different, coupled methods: (i) a RANS method for the analysis of the viscous flow around the ship hull and the determination of the velocity field in th...

Information-theoretic alternatives to general method of moments (GMM) use over-identifying moments to estimate the data-generating distribution jointly with the parameters of interest. This paper demonstrates how these estimates can be interpreted when the sample is not a random draw from the population of interest. I make explicit the selection probability implied by the empirical likelihood a...

nowadays, combination of gps heights with orthometric heights, derived from precise leveling, is broadly used to obtain point-wise solutions of the geoid, which is called “gps/leveling geoid”. the “gps/leveling geoid” is commonly used to constrain the gravimetric geoid solutions in a least squares surface fitting process. in this paper, unlike the usual application, the “gps/leveling geoid” is ...

We discuss the twist map, with a special interest in its use for finite Frenkel–Kontorova model. explain meaning of tensile force some proposed models. demonstrate that application map FK model is not correct, because procedure ignores necessary boundary conditions.

Within the MNPBEM toolbox, we show how to simulate electron energy loss spectroscopy (EELS) of plasmonic nanoparticles using a boundary element method approach. The methodology underlying our approach closely follows the concepts developed by Garćıa de Abajo and coworkers [for a review see Rev. Mod. Phys. 82, 209 (2010)]. We introduce two classes eelsret and eelsstat that allow in combination w...

Loss functions play an important role in analyzing insurance portfolios. A fundamental issue in the study of loss functions involves the selection of probability models for claim frequencies. In this article, we propose a semiparametric approach based on the generalized method of moments (GMM) to solve the specification problems concerning claim frequency distributions. The GMM-based testing pr...

A new multilayer preceptor initialization method is proposed and compared experimentally with a traditional random initialization method. An operator maps training-set vectors into a two-variate space, inspects bi-variate training-set vectors and controls the complexity of the decision boundary. Simulations with sixteen real-world pattern classi®cation tasks have shown that in small-scale patte...
