Problem Solutions of Phase Ambiguity and Initial Phase Shifts of the Phase Radio Navigation System for Aircraft Blind Landing
IJISET - International Journal of Innovative Science, Engineering & Technology, Vol. 2 Issue 3, March 2015. www.ijiset.com ISSN 2348 – 7968 Problem Solutions of Phase Ambiguity and Initial Phase Shifts of the Phase Radio Navigation System for Aircraft Blind Landing 1 2 Saed SasiP ,P Nasar Aldian ShashoaP P 1 P DepartmentP of Electrical and Computer Engineering , Libyan Academy, Jansour, Tripoli, Libya 2 P P Electrical Engineering Departme, Azzaytuna University, Tarhuna, Tripoli, Libya Abstract fast processing capabilities to resolve timing differences This work is a continuation of a design of a phase radio for fine-grained measurements, this problem is amplified navigation system for aircraft blind landing in case of non- over short distances. The other problem with these systems equipped runways proposed in [1], where, the proposed system is is the need to have and maintain high synchronization based on measuring the phase shifts of signals received from four between the transmitter and receiver, which adds an extra ground transmitters (antennas), placed on corners of the runway strip, which provide distance measurements accuracy in burden on the system cost and design. Unfortunately, the millimeters. However, there are two important points that need time of flight measurement is not accurate enough for the serious consideration. First, the phase measurement is going to high demands of landing systems. As third approach, by sending one or two signals of different carrier frequencies, give the total phase (ρ0 − ϕ) , while the actual phase shift of and then measuring the difference of phase shifts of the interest is ‘ϕ ’, ρ is the transmitter initial phase. -

A Novel Approach for Interactive Mobile Augmented Reality System
Recent Advances in Electrical and Electronic Engineering A Novel Approach for Interactive Mobile Augmented Reality System P. SAGAYA AURELIA, DR. OMER JOMAH Department of Computer Science Azzaytuna University LIBYA [email protected], [email protected] Abstract: - Mobile augmented reality is growing rapidly because of the growth of smartphones. Due to the portable nature of smartphones, mobile augmented reality devices have become the most widely deployed consumer augmented reality display device and show promise for becoming the first commercial success for augmented reality technologies. The role of the user is identified and forwarded to the respective module. Cognitive engagement and interactivity are the main two factors of influenced learning where the engagements are focused in Learnability identification module. When a common, single optical tracking platform is available the reachability and performance can also be increased without affecting the efficiency, which will be done in AllinoneAR Module. An integrated framework consisting of three above stated modules is proposed in this paper. Keyword: - Augmented reality, Learnability, usability, authoring, Role 1 Introduction 2 Mobile Augmented Reality While AR technology is steadily maturing, application Augmented reality and mobile computing are often and content development for those systems is still mentioned together, as many mobile computing taking place mostly at source code level. Besides platforms rely on some kind of head-up or head- limiting developer productivity, this also prevents mounted display to provide continuous access to professionals from other domains such as writers, information, often coupled with hands- free operation. designers or artists from taking an active role in Augmented reality as a user interface for mobile development of AR applications and presentations. -

Our whose objective is to classify new observations to one of the simulation results illustrate the usefulness of the proposed existing classes. Many methods have been developed for procedures. supervised classification. Such as the Fisher Discriminant.
