We present the first experimental demonstration (to our knowledge) of long-distance unperturbed fundamental optical soliton transmission in conventional single-mode optical fiber. The virtual transparency in the fiber required for soliton transmission, over 15 complete periods, was achieved by using an ultralong Raman fiber laser amplification scheme. Optical soliton pulse duration, pulse bandw...

We prove the instability of averages of the conductivity in the inverse boundary value problem of Calderón, also known as the inverse conductivity problem or EIT.

Democratic parliamentary and presidential voting supported by election systems worldwide represents the essential idea behind any free society. In recent years, numerous challenges have been overcome to satisfy this fundamental principle. On one side we have low voter turnout and high electors migration, on the other, sometimes complex electoral systems such as preferential or transferable ball...

In a constructive learning setting, a robot builds up beliefs about the world by interacting – interacting with the world, and with other agents. Asking questions is key in such a setting. It provides a mechanism for interactively exploring possibilities, to extend and explain the robot’s beliefs. The paper focuses on how to linguistically phrase questions in dialogue. How well the point of a q...

In this short paper it will be discussed how crowdfunding concepts can be successfully used to support internal financing projects towards Enterprise Crowdfunding. A central platform to be developed will guarantee transparency in order to ease and facilitate synergy-effects between company divisions and departments. Besides transparency crowdfunding – especially through its federalistic financi...
