چکیده

Points:  On-the-go soil sensors are able to map soil texture, organic matter, and pH, along with topography  A multi-sensor system effectively mapped a set of 10 fields across 6 states, delineating variability not detected by USDA soil surveys  A proprietary fuzzy logic system that classifies productivity zones was able to estimate productivity differences  Detailed quantitative soil maps and a novel classification approach are promising developments for improving the effectiveness of variable-rate inputs

The Dependency of Colorimetric Characteristics of Black Fabrics to the Whiteness Attribute of Substrate

In this paper the effect of whiteness attribute of white substrates on blackness property of black coated fabrics is investigated. To this aim, four cotton fabrics with different whiteness and tint attributes are used as white substrates. To prepare a set of black samples, various concentrations of four color pigments, i.e., red, green, blue and yellow, were mixed with the black one and applied...

The Effects of Iranian Gum Tragacanth on the Foaming Properties of Egg White Proteins in Comparison with Guar and Xanthan Gums

ABSTRACT: This paper presents the results of studies concerned with the preparation of fresh food foams based on egg white and various hydrocolloids including Iranian gum tragacanth, guar and xanthan gums at different concentrations (0.002-0.040% w/w). The basic physical parameters of the obtained foams such as overrun, stability and morphology of gas bubbles were measured. Viscosity measuremen...

A High Performance Feedback Active Noise Control System

In many active noise control (ANC) applications, an online secondary path modelling method that uses a white noise as a training signal is required. This paper proposes a new feedback ANC system. Here we modified both the FxLMS and the VSS-LMS algorithms to raised noise attenuation and modelling accuracy for the overall system. The proposed algorithm stops injection of the white noise at the op...

A Robust Feedforward Active Noise Control System with a Variable Step-Size FxLMS Algorithm: Designing a New Online Secondary Path Modelling Method

Several approaches have been introduced in literature for active noise control (ANC)systems. Since Filtered-x-Least Mean Square (FxLMS) algorithm appears to be the best choice as acontroller filter. Researchers tend to improve performance of ANC systems by enhancing andmodifying this algorithm. This paper proposes a new version of FxLMS algorithm. In many ANCapplications an online secondary pat...
