Pressure sensor test evaluation using fractal analysis methods

Evaluation of fractal dimensions for analysis of aggregate stability

Evaluation of methods for estimating fractal properties of intensity images

We have evaluated nine different methods for estimating the fractal dimension of intensity images based on their accuracy, spread and robustness to noise. For this purpose we have generated some 6000 digital images with varying size and known fractal properties. To observe the influence of noise we have distorted these images with Poisson noise, Gaussian noise of different strength and point sp...

EVALUATION OF ISOMETRIC EXERCISE TEST AND ROLL-OVER TEST AS METHODS OF PREGNANCY

 ABSTRACT Background: The incidence of pregnancy induced hypertension (PIH) which is one of the three main causes of maternal-neonatal morbidity and mortality is 5-7%, and prediction of this disorder is very important in maternal and neonatal health. Methods: The type of this study is analytical (comparative-prospective) and its purpose is to evaluate the isometric exercise test (lET) and roll-...

New Design of Mems piezoresistive pressure sensor

The electromechanical analysis of a piezoresistive pressure microsensor with a square-shaped diaphragm for low-pressure biomedical applications is presented. This analysis is developed through a novel model and a finite element method (FEM) model. A microsensor with a diaphragm 1000 „m length and with thickness=400 µm is studied. The electric response of this microsensor is obtained with applyi...

Test Oracles Using Statistical Methods

The oracle problem is addressed for random testing and testing of randomized software. The presented Statistical Oracle is a Heuristic Oracle using statistical methods, especially statistical tests. The Statistical Oracle is applicable in case there are explicit formulae for the mean, the distribution, and so on, of characteristics computable from the test result. However, the present paper onl...
