A Note on the Implementation of the Effective Seismic Input for the Domain Reduction Method
Bulletin of the Seismological Society of AmericaABSTRACT This article presents a simple procedure for evaluating the effective input forces for the domain reduction method and for incorporating these forces into commercial or other production-quality finite-element codes in which access to the element impedance matrices is not readily available.

A new wavenumber-domain method for magnetic reduction to the pole at low latitudes
SEG Technical Program Expanded Abstracts 2013, 2013Summary We propose a new wavenumber-domain method for magnetic reduction to the pole (RTP) at low latitudes, herein called the antisymmetric factor method, based on modification of the RTP factor. The method applies the antisymmetric factor in a given scope of directions centered along the magnetic declination to suppress amplification of the RTP ...

A combined time and frequency domain method for model reduction of discrete systems
Journal of the Franklin Institute, 1981Abstract A new combined time and frequency domain method for the model reduction of discrete systems in z-transfer function is presented. First, the z-transfer functions are transformed into the w-domain by the bilinear transformation, z = (1+w)/(1−w).

Frequency-domain order reduction methods applied to a hydro power system
Archiv für Elektrotechnik, 1988Two frequency-domain reduction (approximation) methods are introduced, for the purpose of applying them to high-degree transfer functions of single-input single-output linear time-invariant systems and obtain corresponding adequate reduced order models. These two reduction methods (i.e.

Some problems in model order reduction using frequency-domain methods
2005Frequency-domain model reduction methods for continuous-time, linear, time-invariant, SISO systems are critically reviewed. Particular attention is given to the Maehly's method which often produces satisfactory results but does not entail matching the first terms of the Che byshev expansions of the original and reduced-order functions.

The common domain-specific approach to reliability improvement and risk reduction created the false perception that effective risk reduction can be successfully delivered solely by using methods offered by the specific domain. In standard textbooks on mechanical engineering and design of machine components, for example, there is no mention of general ...

Application of Order Reduction Methods in Multi-Domain Modelling of Mechatronic Systems
IFAC Proceedings Volumes, 2000Abstract In many cases the information processing part of a mechatronic system consists of a model based controller. The quality of the controller depends highly on the quality of the used behavioural model. This paper proposes order reduction methods to obtain behavioural models of high quality from given finite element (FE) models.

Monte Carlo Noise Reduction Using Bayesian Method in Wavelet domain.
2005A novel post-processing approach for removing Monte Carlo noises in synthetic images is presented in this paper. This paper first presents our findings on the statistical characteristics of the Monte Carlo noise, and then proposes a Bayesian method to remove this noise.
