We propose a method based on minimum-variance polynomial approximation to extract system poles from a data set of samples of the impulse response of a linear system. The method is capable of handling the problem under general conditions of sampling and noise characteristics. The superiority of the proposed method is demonstrated by statistical comparison of its performance with the performances...

This paper discusses two applications of model transformation to method engineering; one is method assembly of diagram based methods and formal methods and the other one is providing formal semantics with meta models by means of the transformation of the meta model descriptions into the formal descriptions. We use Class Diagram to define the meta models, and the models following the meta model ...

The bioinetrical treatment of laboratory data may require the estimation of a regression line for the transformation of one set of measurements to another. The regression procedure introduced in part I (1) of our work does not always yield unbiased results in such situations, since its estimators are not scale invariant. In part III we present the parameter estimation of a general regression eq...

In this paper, we propose a new algorithm to make a novel spatial image transformation. The proposed approach aims to reduce the bit depth used for image storage. The basic technique for the proposed transformation is based of the modulus operator. The goal is to transform the whole image into multiples of predefined integer. The division of the whole image by that integer will guarantee that t...

We propose a transformation-based scheduling algorithm for the problemgiven a loop construct, a target initiation interval and a set of resource constraints, schedule the loop in a pipelined fashion such that the iteration time of executing an iteration of the loop is minimized. The iteration time is an important quality measure of a data path design because it affects both storage and control ...

A technique is presented in order to evaluate the probability of failure in analytical form instead of approximation methods like FORM/SORM and no series expansion is involved in this expression. This technique is based on the Finite Element Method to obtain the expression of the response of stochastic systems, and the transformation of random variables to obtain the probability density functio...

The paper presents the impedance measurement method using a real-life step pulse as a perturbation signal and Laplace transformation as a tool for analyzing the response of the object under test. The method is addressed to explore different technical object (like anticorrosion coatings, gas sensors, ceramics, dielectrics biological tissues etc.) when the measurement time cannot be long. The pre...

background: according to quality transformation of services during the time, the quality requirements and standards also change and recognition of these requirements and transformation process can assist in recognizing the quality dimensions of services. the aim of this research was to explain the transformation process, requirements and quality dimensions of services in hospitals.   methods: t...

Further to a recent controversy on whether or not the differential transformation method (DTM) for solving a differential equation is purely and solely the traditional Taylor series method, it is emphasized that the DTM is currently used as a technique for calculating the power series of the solution (in terms of the initial value parameters) including, sometimes, a piecewise analytic continuat...
