Conference Paper
The article presents a new approach for the design of an Ultra-wideband (UWB) indoor positioning system (IPS) for position control of a mecanum driven robotic platform. The IPS was constructed using Decawave MDEK1001 development kit. The robotic platform, run by an ATmega2560 microcontroller, achieved an X-Y location accuracy of 7 cm. HC-12 Bluetoo...
Conference Paper

This paper discusses the development of an autonomous indoor location guidance system designed to guide visitors with navigating a college campus department. Advanced programming fea...
Conference Paper
The tremendous demand for water in the agricultural sector in Saudi Arabia poses a great challenge to the government. Bluntly regulating the water supply to farms as a solution for this challenge is not an option, because farming is one of the most important businesses, and it should not be threatened. A substantial percentage of that demanded wate...

An increasing number of Muslims are performing Hajj (Pilgrimage) every year. Hajj is performed around the City of Makkah in Saudi Arabia during five specific days of the year. It is expected that more than five million pilgrims will perform Hajj in the year 2020 which will increase the burden on the already strained medical, logistical, transportat...
Article
In this paper, we addressed the problem of estimating the two-dimensional (2D) Direction of Arrival (DOA) elevation and azimuth angles for multiple sources. The proposed method employs Propagator Method (PM) in conjunction with parallel factor (PARAFAC) model using a new antenna array configuration. The proposed method overcomes two main drawbacks...
