Abstract: In this paper, the Autocovariance Least Squares (ALS) technique is proposed for detecting the Global Positioning System (GPS) measurements’ interference or jamming. The interference is modeled by a moderate increase in the measurements noise covariance matrix while jamming is modeled by a larger increase in the measurements noise covariance matrix. The method makes use of the dynamics...

Pedomodels have become a popular topic in soil science and environmentalresearch. They are predictive functions of certain soil properties based on other easily orcheaply measured properties. The common method for fitting pedomodels is to use classicalregression analysis, based on the assumptions of data crispness and deterministic relationsamong variables. In modeling natural systems such as s...

subdomains exist. They include methods using unstructured meshes, body-fitted curvilinear meshes, and Cartesian meshes. This paper discusses an approach that uses “gridless” or “meshless” methods to address the boundary or interface while standard structured grid methods are used everywhere else. The present method uses the Cartesian grid to specify and distribute the computational points on th...

The Adaptive Least Squares Correlation is a very potent and flexible technique for all kinds of data matching problems. Here its application to image matching is outlined. It allows for simultaneous radiometric corrections and local geometrical image shaping, whereby the system parameters are automatically assessed, corrected, and thus optimized during the least squares iterations. The various ...

Color correction is an image-altering technique that modifies image color in such a way it matches reference image. Many approaches have already been proposed by various researchers; however, those models unable to reduce errors between two images, which results inefficiency and poor-quality images. This research paper presents effective improved model wherein alternate least square (ALS) root ...
