This paper presents a comparative evaluation of liquid-crystal display (LCDs) and cathode-ray tube (CRT) displays from a color-rendition and color-calibration perspective. Common display calibration models and assumptions are reviewed and their applicability to LCDs and CRTs is evaluated through an experimental study. The displays are compared with respect to the color-calibration accuracy, eas...

recently, with increasing public awareness of food safety, developments of some valid and rapidly analytical methods are required for the determination of residual pesticides in crops.this study was conducted on validation of a reliable, accurate and precise method for multi analysis of pesticides residue in melon as a main fruit in iranian food basket. a reliable, and valid method based on spi...

In this paper we consider several parametric assumptions for the instantaneous covariance structure of the Libor market model. We examine the impact of each different parameterization on the evolution of the term structure of volatilities in time, on terminal correlations and on the joint calibration to the caps and swaptions markets. We present a number of cases of calibration in the Euro mark...

We present a simple method to determine the polarimetric properties of spatial light modulators (SLMs) for each grey level by means irradiance measurements. The Jones matrix SLM is obtained without any assumption about its properties, so it can be applied more devices than previous works. This enough quickly performed, while offers better results works, as reduces error in prediction transmissi...

multi-drug therapy in high blood pressure is appreciated to achieve a normalblood pressure.a simple spectrophotometric method based on principal component analysis has been proposed for simultaneous determination of amlodipine (amd) and metoprolol(met) in pharmacutical preparations. calibration matrix contains 3.402 µgml -1 to 170.130 µgml -1 and from 13.060 µgml -1 to 65.3 µgml -1 amlodipine a...

—Modulated Wideband Converter (MWC) is a type of theory to real-time sub-Nyquist sampling and recovery of sparse wideband analog signal with low computational overhead and efficient hardware implementation. However, the application and implementation of MWC are seriously disturbed by the measurement matrix mismatch problem caused by limited system bandwidth and inevitable nonlinearity of pract...

Calibration is one of the most important technologies for line-structured light vision sensor. The existing calibration methods depend on special calibration equipments, whose accuracy determines the calibration accuracy. It is difficult to meet the requirements of universality and field calibration with those methods. In order to solve these problems, a new calibration method based on the comb...
