We study the precision with which the sign of δm232 can be determined at a neutrino factory, as a function of stored muon energies and baselines. This is done by simultaneously fitting the channels νμ → νμ , ν̄e → ν̄μ from μ− decays and the channels ν̄μ → ν̄μ , νe → νμ from μ decays. For a 20 GeV muon storage ring we investigate as a function of the baseline length and the magnitude of δm232, the m...

In dilation or erosion processes, a shock filter is widely used in signal enhancing or image deburring. Traditionally, sign function is employed in shock filtering for reweighting of edge-detection in images and decides whether a pixel should dilate to the local maximum or evolve to the local minimum. Some researchers replace sign function with tanh function or arctan function, trying to change...

For the hearing impaired, sign language is the most prevailing means of communication for their day-to-day life. It is always a challenge to develop an optimized automated system to recognize and interpret the implication of signs expressed by the hearing impaired. There are a wide range of algorithms developed for SLR, in which only few considerable approaches are carried out in Tamil Sign Lan...

We define and study cocycles on a Coxeter group in each degree generalizing the sign function. When is Weyl group, we explain how three cocycle arises naturally from geometric representation theory.

In this lecture, we will discuss the emergence of the semiotic function, both ontogenetically and phylogenetically, and we will consider the part played by the picture sign in this development. In order to demonstrate that pictures are indeed signs, we will explore the basic elements of the sign presupposed but never put into focus neither by Saussure nor by Peirce. Indeed, explorations in the ...

Many real-world applications require minimization of a cost function. This function is the criterion that figures out optimally. In the control engineering, this criterion is used in the design of optimal controllers. Cost function optimization has difficulties including calculating gradient function and lack of information about the system and the control loop. In this article, for the first t...
