Magnetic Field Prediction in Cubic Spoke-Type Permanent-Magnet Machine Considering Magnetic Saturation

In this article, a nonlinear semianalytical model (SAM) is presented to predict the magnetic field distribution (MFD) and electromagnetic performances (EPs) in the cubic spoke-type permanent magnet (PM) machine. To model the rectangular PMs, the rectangular PM is simplified as a combination of fan-shaped regions with different arc angles....

Semianalytical Model of Multiphase Halbach Array Axial Flux Permanent-Magnet Motor Considering Magnetic Saturation

This article proposes a nonlinear semianalytical model (SAM) of the multiphase Halbach array axial flux permanent-magnet motor (AFPMM) to speed up the computation of its magnetic field. Compared to the existing analytical models, the proposed nonlinear SAM can directly consider magnetic saturation to obtain more accurate results. To this end,...

Grasping the Sampling Behaviour of Event-Triggered Control: Self-Triggered Control, Abstractions and Formal Analysis

A fundamental challenge in networked control systems is reducing the amount of communications of each system in the network, so that bandwidth and energy are used efficiently. To address the challenge, the research community has shifted its focus to Event-Triggered Control (ETC), in which communication between the control system's different...

Review and perspectives in quantum computing for partial differential equations in structural mechanics

Structural mechanics is commonly modeled by (systems of) partial differential equations (PDEs). Except for very simple cases where analytical solutions exist, the use of numerical methods is required to find approximate solutions. However, for many problems of practical interest, the computational cost of classical numerical solvers running on...

Quantifying nonlinear contributions to cortical responses evoked by continuous wrist manipulation

Cortical responses to continuous stimuli as recorded using either magneto- or electroencephalography (EEG) have shown power at harmonics of the stimulated<br/>frequency, indicating nonlinear behavior. Even though the selection of analysis techniques depends on the linearity of the system under study, the importance of nonlinear contributions to...

Uncertainty in centrifuge test of slope failure and its simulation by MPS method

We sometimes encounter a case in which very small change of computation or experiment condition causes the significant difference in response when strong nonlinearity is involved. Slope failure simulation due to gravity by MPS method is performed to examine feature of uncertainty. The simulation results show that the output uncertainty is...

Simulation of masonry beams retrofitted with engineered cementitious composites

Re-entry flight clearance

The objective of the research was to identify and evaluate promising mathematical techniques for re-entry flight clearance. To fulfil this objective, two mathematical methods were investigated and developed: μ analysis for linear models and interval analysis for both linear and non-linear models. The stability of re-entry vehicles in the...

Nonlinear Evolution of Shear Instabilities of the Longshore Current

Surface gravity waves breaking in the nearshore region force a longshore surf zone current. This current can be unstable to longshore periodic perturbations. The continuity and momentum conservation equations averaged over the short wave time scales and over depth present a suitable basis for the modeling of these motions. The governing...

An experimental and numerical study on jack-up dynamic behavior

This paper presents the more salient results of an experimental and numerical study on jack-up dynamic behavior. The laboratory studies of three principle jack-up platform models were carried out in both regular and irregular waves. The data from irregular wave tests were analyzed in both the probability domain and frequency domain supported by...

Bordered equations in continuation methods: an improved solution technique

Continuation methods with adaptive path parameters, such as arc-length continuation, are based on bordered equations where the governing matrix is nonsymmetric with respect to one column and row. In the conventional way of solving these systems, the factored submatrix of the total system becomes singular at special solution points such as limit...
