Underwater mobile gravity measurement data processing using continuous-discrete Kalman filter
AIP Advances, 2021 To solve the data fusion problem in underwater mobile gravity measurement, a direct estimation method based on pose information is proposed. First, the state model is established using the continuous evolution equation of the state.

Nonparametric Clustering of Mixed Data Using Modified Chi-Squared Tests
Entropy, 2022 We propose a non-parametric method to cluster mixed data containing both continuous and discrete random variables. The product space of the continuous and discrete sample space is transformed into a new product space based on adaptive quantization on the

Discrete, continuous, and combined simulation [PDF]
Proceedings of the 20th conference on Winter simulation - WSC '88, 1987 This tutorial paper introduces the major types of simulation models: discrete, continuous, and combined. It concentrates on illustrating the models by describing their variable characteristics, through modeling a liquid waste disposal system, first as a continuous sub-model, next a discrete sub-model, finally as a unified combined model.

Probabilistic Power Flow Method Considering Continuous and Discrete Variables
Energies, 2017 This paper proposes a probabilistic power flow (PPF) method considering continuous and discrete variables (continuous and discrete power flow, CDPF) for power systems. The proposed method—based on the cumulant method (CM) and multiple deterministic power

3-D FEM analysis of the effects of SPT head dimensions on recording in discrete and continuous media [PDF]
, 2005 Due to the considerable increase of magnetic recording density, the deviation of the head from the centerline of the track becomes a serious problem for the cross-track interference.

Simulations of discrete quantum systems in continuous euclidean time [PDF]
Nuclear Physics B - Proceedings Supplements, 1996 Path integrals are usually formulated in discrete Euclidean time using the Trotter formula. We propose a new method to study discrete quantum systems, in which we work directly in the Euclidean time continuum. The method is of general interest and can be applied to studies of quantum spin systems, lattice fermions, and in principle also lattice gauge ...

Ensemble unscented Kalman filter for state inference in continuous–discrete systems
The Journal of Engineering, 2014 The authors consider non-linear state filtering problem in continuous–discrete systems, where the system dynamics is modelled by a stochastic differential equation, and noisy measurements of the system are obtained at discrete time instances.

On the relationship between continuous- and discrete-time quantum walk [PDF]
, 2008 Quantum walk is one of the main tools for quantum algorithms. Defined by analogy to classical random walk, a quantum walk is a time-homogeneous quantum process on a graph. Both random and quantum walks can be defined either in continuous or discrete time.
