Like other divergences, Jeffrey's divergence (JD) is used for change detection, for model comparison, etc. Recently, a great deal of interest has been paid to this symmetric version of the Kullback-Leibler (KL) divergence. This led to analytical expressions of the JD between autoregressive (AR) processes, moving-average (MA) processes, either noise-free or disturbed by additive white noises, as well...
This paper deals with the analysis of the Jeffrey's divergence (JD) between an autoregressive process (AR) and a sum of complex exponentials (SCE), whose magnitudes are Gaussian random values, which is then disturbed by an additive white noise. As interpreting the value of the JD may not be necessarily an easy task, we propose to give an expression of the JD and to analyze the influence of each process...
One of the main remote sensors used for monitoring snow covered areas is the Moderate Resolution Imaging Spectroradiometer (MODIS) employed by NASA's Terra and Aqua satellites. Using MODIS-derived snow cover images is limited under cloud-covered regions due to the sensor's capabilities. This paper presents an automated process based on K-Nearest Neighbor (KNN) algorithm using spatiotemporal features,...
Soil moisture sensors are used mainly to help farmers to plan irrigation scheduling and save fresh water usage. The measurement of soil moisture based on electrical resistivity is widely used by farmers due to its simplicity and low cost. This research aims to evaluate the performance of low-cost resistive soil moisture sensors under greenhouse conditions. For this purpose, sensors have been assessed...
Recently, several studies were implemented in the mobile robotics field showing the great interest in developing automated algorithms for performing daily tasks. This paper discusses the implementation of an enhanced algorithm in performing autonomous parallel parking for a car-like mobile robot based on the traditional geometric approach. The developed algorithm depends mainly on the geometric dimensions...
Gastric leak after laparoscopic sleeve gastrectomy (LSG) is a serious complication. Currently, the literature lacks long-term outcomes in LSG and leak rates after reinforcement of the staple line. The aims are two-fold: to present leak rates from using staple line reinforcement and six year outcomes of LSG in relation to resolution of obesity-related comorbidities and long-term weight loss.This is...
Snow Cover Area monitoring is an important factor in studies of global climate change, regional water balance and soil moisture. Recently, the usage of remote sensing techniques has flourished. In fact, remote sensing data provides timely adequate snow cover information for large areas. While the National Center for Remote Sensing in Lebanon (CNRS) has recently established an operational monitoring...
Water resources for agricultural development and landscape enhancement in Kuwait are very scarce; the quality is saline (brackish), and the soil texture is sandy, incapable of holding nutrients and moisture. Most of the rainfall in Kuwait either evaporates due to the high temperatures or percolates through the soil. The rainfall is not sufficient to recharge the underground water supply. A variety...
