the potential of near infrared reflectance spectroscopy (nirs) as a fast method to predict the crude protein (cp) and moisture (m) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on partial least squares (pls) was evaluated. the coefficient of determination in calibration (r2c) and standard error of calibration (sec) were 0.95 and 1...

introduction: the aim of this in vitro study was to evaluate the setting time, flow, film thickness, solubility, radiopacity and characterization analysis of three epoxy resin based sealers including two experimental sealers and ah-26. methods and materials: five samples of each material were evaluated for setting time, flow, film thickness, solubility and radiopacity according to iso 6876 stan...

This paper deals with the problem of tracking an object from a sequence of images captured from a camera moving towards the object. Many conventional image based trackers trace key reference points over an image sequence using simple correlation processes 1]. However, the presence of noise and the magniication of image features as the camera approaches the object may cause a tracked point to dr...

0. Abstract In this paper we propose a simple enhancing protocol for pulsed infrared thermography. The method is based on stimulating the specimen with two heating pulses separated by a short time interval delta. This approach was tested on several specimens of low and high thermal diffusivity and showed to provide higher thermal contrasts when an optimum interval delta is chosen. The observed ...

various destructive and non-destructive methods are used to measure the maturity and internal quality parameters of fruits. destructive methods often consume time and are costly. in this study, the ability of near infrared spectroscopy for prediction of the quality properties such as soluble solids content, titratable acid, ph, total phenol and extract anthocyanin of 'bidaneh ghermez'...

In this study, visible-near infrared spectroscopy and mid-infrared spectroscopy were compared to evaluate their applicability in classifying citrus leaves infected with canker and Huanglongbing (HLB) from healthy citrus leaves. The visible-near infrared spectra in the range 350-2,500 nm and mid-infrared spectra in the range of 5.15-10.72 μm were collected from healthy and diseased (canker, HLB)...

OBJECTIVE Near-infrared spectroscopy correlation with low cardiac output has not been validated. Our objective was to determine role of splanchnic and/or renal oxygenation monitoring using near-infrared spectroscopy for detection of low cardiac output in children after surgery for congenital heart defects. DESIGN Prospective observational study. SETTING Pediatric intensive care unit of a te...

Binary water mixtures usually display a water relaxation (process II) which can be studied by broadband dielectric spectroscopy (BDS) at subzero temperatures. In a large collection of binary water mixtures, a slight increase of the relaxation strength is observed for low water concentration, whereas a faster increase is seen above a critical concentration. The assumption behind this result is t...
