Quasi-phase-matched (QPM) GaAs structures, 0.5 mm thick, 10 mm long, and with 61-mum grating periods, were grown by a combination of molecular-beam epitaxy and hydride vapor phase epitaxy. These were characterized by use of mid-IR second-harmonic generation (SHG) with a ZnGeP(2) (ZGP) optical parametric oscillator as a pump source. The SHG efficiencies of QPM GaAs and QPM LiNbO(3) were directly...

Various types of multi-view camera systems have been proposed for capturing three dimensional scenes. Yet, color distributions among multi-view images remain inconsistent in most cases, degrading multi-view video coding performance. In this paper, we propose a color correction algorithm based on the camera characteristics to effectively solve such a problem. Initially, we model camera character...

In the image parameter estimation by the linear regression, it has very high degrees of freedom for the decision of regression coefficients, because the dimension of image vector is huge high. In this paper, we discuss its potential by the learning of the dense samples. For the learning process, we employed a sequential regression coefficient calculation algorithm and realize its calculation fo...

In networks with small-world topology, which are characterized by a high clustering coefficient and a short characteristic path length, information can be transmitted efficiently and at relatively low costs. The brain is composed of small-world networks, and evolution may have optimized brain connectivity for efficient information processing. Despite many studies on the impact of topology on in...

In this research paper, we have discussed the estimation of location and scale parameters of Weibull distribution using concept of generalized order statistics by the best linear unbiased estimator (BLUE) and an alternative linear estimates (Gupta) from Type II singly and doubly censored samples. Tables of coefficients for best linear estimator and alternative estimator of μ and λ have been obt...

Word-of-Mouth plays its great important role on the base of social network in affecting consumers’ shopping behaviour. However, it is little known how firms make a self-suitable marketing strategy according to both online and offline WOM effect in their product diffusion. This article investigates a new product diffusion process taking both offline WOM and online WOM effect into consideration. ...

Difference expansion (DE) has been widely used for reversible data hiding. In this paper a novel transform which embeds two bits of information in a triplet of coefficients is presented. This transform can be applied in spatial or frequency domain and induces minimum distortion to the initial data or coefficients. The proposed method outperforms all similar DE methods using triplets in terms of...

We introduce the Randomized Dependence Coefficient (RDC), a measure of nonlinear dependence between random variables of arbitrary dimension based on the Hirschfeld-Gebelein-Rényi Maximum Correlation Coefficient. RDC is defined in terms of correlation of random non-linear copula projections; it is invariant with respect to marginal distribution transformations, has low computational cost and is ...

A parametric optimality principle (choice function) in a finite cooperative game of several persons is determined. This principle is specified by means of partition of players set into coalitions. It generates a set of generally efficient situations. Extreme cases of such a partition correspond to Pareto optimal situation and Nash equilibrium situation. For a situation, efficient for a given pa...

We analyze the simplest Condorcet cycle with three players and three alternatives within a strategic bargaining model with recognition probabilities and costless delay. Mixed consistent subgame perfect equilibria exist whenever the geometric mean of the agents’ risk coefficients, ratios of utility differences between alternatives, is at most one. Equilibria are generically unique, Pareto effici...
