{Zusammenfassung Convergence Acceleration for Some Roottnding Methods. We present simple, eecient extrapolation formulas to accelerate the convergence of super-linearly convergent sequences. Applications are given for some roottnding methods such as Newton's method and the secant method. Numerical examples are given showing the eeectiveness of the extrapolation formulas. die EEektivitt at der E...

This paper presents the effective method for dynamic stress analysis of structural components of bus systems or general mechanical systems. The proposed method is the hybrid superposition method that combined finite element static and eigenvalue analysis with flexible multibody dynamic analysis. In the stress recovery, dynamic stresses are calculated through sum of pseudostatic stresses and mod...

initially, the first aim of the present study is to model 3-axle rigid truck by developing a code inmatlab. secondly, each equation should be drived by acquisition of lagrange approach. afterderiving equations successfully, validation is performed by some result which was mentioned inbohao li's master thesis. although the present approach is totally different from the approachthat boahao li use...

A modification of the Adomian decomposition method applied to systems of linear/nonlinear ordinary and fractional differential equations, which yields a series solution with accelerated convergence, has been presented. Illustrative examples have been given. 2006 Elsevier Inc. All rights reserved.

The X window system is generally implemented by directly inserting hardware manipulation code into the X server. Mode selection and 2D acceleration code are often executed in user mode and directly communicate with the hardware. The current architecture provides for separate 2D and 3D acceleration code, with the 2D code executed within the X server and the 3D code directly executed by the appli...

The growth of the two-dimensional single-mode Rayleigh-Taylor instability (RTI) at low Atwood number (A=0.04) is investigated using Direct Numerical Simulations. The main result of the paper is that, at long times and sufficiently high Reynolds numbers, the bubble acceleration becomes stationary, indicating mean quadratic growth. This is contrary to the general belief that single-mode Rayleigh-...

We propose the structure to have only two pares of PZT thin films on the basis of [11]. This causes the structure to become simpler and easier to fabricate. And except its first vibration mode that is also the base mode, the other modes have no effect on the acceleration measurement. So it can be a better choice for the measurement of acceleration and it can have a huge potential as a micro-sen...

Starting from a fixed point relation, we construct very fast iterative methods of Ostrowski-root’s type for the simultaneous inclusion of all multiple zeros of a polynomial. The proposed methods possess a great computational efficiency since the acceleration of the convergence is attained with only a few additional calculations. Using the concept of the R-order of convergence of mutually depend...

This paper demonstrates the possibility to detect suspension failures of railway vehicles using a multiple-model approach from on-board measurement data. The railway vehicle model used includes the lateral and yaw motions of the wheelsets and bogie, and the lateral motion of the vehicle body, with sensors measuring the lateral acceleration and yaw rate of the bogie, and lateral acceleration of ...
