Watermarking is one of the best solutions for copyright protection and authentication of multimedia contents. In this paper a hybrid scheme is proposed using wavelet and shearlet transforms with singular value decomposition. For better security, Arnold map is used for encryption. Examining the results and comparing with other methods show that this hybrid proposed scheme with simultaneous utili...

The emergent consensus on dimensional models of sentiment, appraisal, emotions, and values is on the semantics of the principal dimensions, typically interpreted as valence, arousal, and dominance. The notion of weak semantic maps was introduced recently as distribution of representations in abstract spaces that are not derived from human judgments, psychometrics, or any other a priori informat...

We studied that arbitrary 2-dimensional maps are Hamilton system if a initial value of map is a ”time” variable. In this paper, we generalize this correspondence, and show that an n-dimensional map is a Nambu system in which one of initial values of the map play a role of ”time” variable.

The present work displays an investigation focused on the understanding of sociology institutionalization in Mexico, and if it is possible to be spoken of an academic crisis of sociology, as it is handled nowadays, besides an investigation that takes care of specific values of the sociological knowledge in the reality of each region in Mexico. This approach starts, firstly, in a study of the so...

Modeling of large systems requires high level of expertise to properly identify and represent complex interrelationships between various elements. In addition to creation of a network of system’s elements and their relationships, very important contribution to understanding of its behavior we can get from human experts. Naturally, humans express their experience and beliefs descriptively, empha...

Fuzzy Cognitive Maps (FCMs) have found many applications in social -financial -political problems. In this paper we propose a method of FCM operation, which can be used to represent and control any real system, including traditional electro-mechanical systems. In the proposed approach the FCM reaches its equilibrium point using direct feedback from the node values of the real system and the lim...

In GIS system, we often use vector contour map to show or locate position on the earth. Since such map data is very worthy of value, it is necessary and important to protect its copyright. In this paper, we propose a new method to embed watermark into the angle parameter of polygonal lines or curves in a contour map after its parameterization. The watermark can be detected as proof of the owner...

The performance of MMSE Iterative Equalization based on MAP-SBVP and COD-MAP algorithms (for generating extrinsic information) are compared for fading and non-fading communication channels employing serial concatenated convolution codes. MAP-SBVP is a convolution decoder using a conventional softMAP decoder followed by a soft-convolution encoder using the soft-boolean value propagation (SBVP). ...

The author has already developed and evaluated a term paper grading assistance map. The map was designed to visualize scores graded for term papers assigned to a class at the university level or the equivalent. The map is a new visualization technique to show the amount of words and word use. This paper introduces prototype system of an assistance map using singular value decomposition techniqu...

It is well known that the absolute value map on the self-adjoint operators on an infinite dimensional Hilbert spaces is not Lipschitz continuous, although Lipschitz continuity holds on certain subsets of operators. In this note, we provide an elementary proof that the absolute value map is Lipschitz continuous on the set of all operators which are bounded below in norm by any fixed positive con...
