We propose a multi-parameter quantum metrological protocol based on Mach-Zehnder interferometer with squeezed vacuum input state and an anti-squeezing operation at one of its output channels. A simple intuitive geometrical picture the evolution is provided by marginal Wigner functions each channel. The allows to detect value sum $\beta=\frac{1}{2}(\varphi_1+\varphi_2)+\theta_\mathrm{in}-\theta_...

Estimating the 3D pose of an object is a challenging task that can be considered within augmented reality or robotic applications. In this letter, we propose novel approach to perform 6 DoF estimation from single RGB-D image. We adopt hybrid pipeline in two stages: data-driven and geometric respectively. The step consists classification CNN estimate 2D location image local patches, followed by ...

this paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. the given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. moreover, robust control laws are designed to guarantee the practical stability of the perturbe...

background and objectives: a sudden jump in blood demand during natural disasters may have strong negative impact on the performance of blood supply chain. appropriate response to the emergency situations, requires predictive approach to determining the optimal allocation of blood supply chain resources for various disaster scenarios. the present study, thus, presents an optimization model aime...

the networked control system in modern control widely uses to decrease the implementation cost and increasing the performance. ncs in addition to its advantages is inevitable. nevertheless they suffer of some limitations and deficiencies. packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. for this reason...

We consider the problem of designing an efficient and robust distributed random number generator for peer-to-peer systems that is easy to implement and works even if all communication channels are public. A robust random number generator is crucial for avoiding adversarial join-leave attacks on peer-to-peer overlay networks. We show that our new generator together with a light-weight rule recen...

We designed an on-chip transformative optic system with a broadband metalens coupler on foundry compatible silicon photonic platform. By adjusting the metalens’ focusing length and mode dimension, insertion loss between crystal waveguide (PhC WG) structures is reduced to 2 dB by matching focal plane PhC WG mode. Alternatively, integrated allow for direct coupling from multi-mode cavity. The on-...

The problem of optimal power allocation among light emitting diode (LED) transmitters in a visible light positioning (VLP) system is considered for the purpose of improving localization performance of visible light communication (VLC) receivers. Specifically, the aim is to minimize the Cramér-Rao lower bound (CRLB) on the localization error of a VLC receiver by optimizing LED transmission power...
