Introduction

Osama Atef Al Najjar is a notable inventor based in Dhahran, Saudi Arabia. He has made significant contributions to the field of soil analysis, holding a total of 4 patents. His work focuses on developing advanced methods and devices for surveying and analyzing soil samples.

Latest Patents

One of his latest patents is a method for surveying and analyzing soil samples in a geographic area. This field portable device is designed to determine the unconfined compressive strength of a soil sample. It includes a sample holder, a heating device, a scale, a spectrometer, and a microprocessor. The sample holder receives a soil sample, while the heating device dries the sample for a specified time. The scale measures both the weight of the soil sample and its dried weight. The spectrometer performs laser-induced breakdown spectroscopy on the soil sample, generating spectral emission intensities. The microprocessor calculates the bulk density and water content of the soil sample, actuates the spectrometer, and applies the spectral emission intensities, bulk density, and water content to a trained machine learning regressor combined with an adaptive boosting classifier to predict the unconfined compressive strength of the soil sample.

Another significant patent is the wheeled soil analysis analyzer for soil compressive strength. This device shares similar components and functionalities with the previous invention, emphasizing the importance of accurate soil analysis in various applications.
