Considering features, such as obvious nonlinear and chaotic characteristics, of the time series of landslide displacement, this paper proposed a wavelet analysis and support vector machine coupling model (WA-SVM) to predict the displacement of a landslide. The monitored time series of displacement firstly is decomposed into several components, including high frequency components and low frequen...

Errors during manufacture of high value components are not acceptable nowadays in driving industries such as energy and transportation. Sectors such as aerospace, automotive, shipbuilding, nuclear power, large science facilities or wind power manufacture complex and accurate components that demand close measurements and fast feedback into manufacturing processes. New measuring technologies are ...

We consider the optimal design of a machine frame under several stress constraints. The shape optimization is based on a Quasi-Newton Method. We need to solve the plain stress state equations in a complex domain for each evaluation of the objective therein. The complexity and robustness of the optimization depends strongly on the solver for the pde. Therefore, solving the direct problem require...

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

This paper is about the construction of various specific machine learning paradigms using a primitive-based generic machine learning model. The generic model identifies five functional components involved in a machine learning process, including an input, a transformation, a control, an output, and a knowledge base. It also identifies a set of basic machine learning mechanisms for each componen...

This paper deals with the analysis of different PM machines for hybrid electric vehicles application. The main machine parameters, electromagnetic torque and the skewing effect is investigated using ANSYS program. The model parameters of the PM machines are derived with Fixed Permeability Method (FPM). With this method the components of the PM machine can be calculated with high accuracy. Diffe...

An alternative technique for the geometric test of machining centres was developed, to congregate metrological reliability with operational and economical advantages, when comparing to methods classically used for such task. A touch probe is used on a 3-axis vertical machine center to check against artifacts calibrated on a coordinate measuring machine (CMM). By comparing the results obtained f...

Recently the number of designed modular machine was increased. The term modular machine is used to denote different types of machinery, equipment and production lines, which are created using modular elements. Modular could be both mechanic elements, and drives, as well as control systems. This method of machine design is more and more popular because it allows obtaining flexible and relatively...
