Phase drift extremely limits the secure key rate and transmission distance, which is non-negligible in local oscillation continuous variable quantum distribution (LLO CV-QKD). In order to eliminate impact caused by phase drift, we analyze noise of system propose a compensation method based on convolutional neural network (CNN). Moreover, performed signal according estimated value before coheren...

In data stream mining, the emergence of new patterns or a pattern ceasing to exist is called concept drift. Concept drift makes the learning process complicated because of the inconsistency between existing data and upcoming data. Since concept drift was first proposed, numerous articles have been published to address this issue in terms of distribution analysis. However, most distributionbased...

A Hamiltonian formulation is constructed for a finite ion Larmor radius fluid model describing ion temperature-gradient driven and drift Kelvin-Hemholtz modes. The Hamiltonian formulation reveals the existence of three invariants obeying detailed conservation properties, corresponding roughly to generalized potential vorticity, internal energy, and ion momentum parallel to the magnetic field. T...

In this paper, we discuss the prediction problem based on censored coherent system lifetime data when the system structure is known and the component lifetime follows the proportional reversed hazard model. Different point and interval predictors based on classical and Bayesian approaches are derived. A numerical example is presented to illustrate the prediction methods used in this paper. Mont...

3D object matching and registration on point clouds are widely used in computer vision. However, most existing cloud methods have limitations handling non-rigid sets or topology changes (e.g. connections separations). As a result, critical characteristics such as large inter-frame motions of the may not be accurately captured. This paper proposes statistical algorithm for registration, addressi...

introduction: wind erosion is one of the most important factors in desert environments. prevailing winds can shift sand dunes and affect their accumulation and morphology. also, wind regime determines the direction of sand dune mobility in different ways. therefore, the wind regime, frequency, direction and velocity are supposed to be the most important factors to form the morphology of sand du...
