We shall study the paper [3] by H.Föllmer and A. Schied. Here theauthors introduce the notion of a convex measure of risk, an extensionof the concept of a coherent risk measure defined in Artzner et al.(1999), and they prove a corresponding extension of the representationtheorem in terms of probability measures on the underlying space ofscenarios. As a case study, they c...

considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. these states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. the states revealing maximum entanglement also display the maximum violations of the be...

This paper presents a new approach to the problem of gap bridging and junction detection. Perceptual groupings and evidence from existing boundaries are combined to produce joins which are consistent with the initial image structure. In particular, a new definition of co-curvilinearity, which distinguishes between true and false co-curvilinearity, is given. Structural quantities are computed fo...

We show theoretically and experimentally that two-photon coherent control in a V -shape three-level system projects a one-photon coherent transient in a simple two-level system. The secondand third-order spectral phase terms of a shaped laser pulse play the roles of time and quadratic spectral phase, respectively, in conventional coherent transients. In a three-pulse coherent control experiment...

‎In this paper‎, ‎the concept of joint reliability importance (JRI) of two or groups of components in a coherent system with independent components have been studied‎. ‎The JRI is defined as the rate at which the system reliability improves as the reliabilities‎ ‎of the two or groups of components improve‎. ‎Generally‎, ‎the sign and the value of the JRI represent the type and the‎ ‎degree of i...

Coherent one-photon (2v) and two-photon (v) electronic excitations are studied for graphene sheets and for carbon nanotubes using a long-wavelength theory for the low-energy electronic states. For graphene sheets we find that a coherent superposition of these excitations produces a polar asymmetry in the momentum space distribution of the excited carriers with an angular dependence that depends...

stepped frequency radars attract many attentions due to their high range resolution. conventional processing technique in these radars is based on the idft. in detecting moving targets, the idft has the problems of range shifting and range spreading, which result in degrading target amplitude, loss of range accuracy and range resolution. to overcome these problems, the velocity compensation met...

We analyze detailed properties of BPS coherent states and their connection to gravity. interpret the group integral state as a path over auxiliary variables coupled elementary letters theory. The eigenvalues amplitudes can be viewed collective coordinates giant gravitons. Inspired by above integrability, we construct new type in SL(2) sectors cousin PSU(1,1|2) sectors, analogous aforementioned ...

The generation of coherent Terahertz (THz) radiation is studied which is produced from moving the relativistic electron beam through a helical wiggler with axial magnetic field. The relativistic electron beam is modulated via interacts with the beat wave of two laser beams that have frequency difference in THz range. When the modulated relativistic beam of electrons go through the helical wiggl...

:This paper speak to the investigation of correspondence in numerous info different yield (MIMO) for open circle transmission remote frameworks .The reasonable and testing non-lucid setup (channel state data is truant at the recipient) is considered. A summed up probability proportion test (GLRT)like finder is expected at the collector and in opposition to most existing methodologies, a subject...
