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.

Hybrid simulation of interacting discrete and continuous systems [PDF]
Proceedings of the 7th conference on Winter simulation - WSC '74, 1974 In this paper, the simulation of interacting discrete and continuous systems on a hybrid computer is discussed. A hybrid computer was chosen mainly for the relative ease with which display facilities could be employed, and for the on-line interaction capability available in a hybrid computer environment.

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.

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

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 ...

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

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.

Synchronization of Continuous Time and Discrete Events Simulation in SystemC
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2021 Modeling and simulation of cyber-physical devices is difficult because of their heterogeneity: they mix discrete-event (DE) hardware and software with continuous time (CT) physical processes. DEs simulation progresses by discrete timesteps while CT simulation does so in a time continuum; despite different time representations, data must be transmitted ...
