Abstract Optical Signal regeneration in all-optical domain has played a vital in role for long haul optical communication systems. On contrary, the electronic regeneration systems have limitations in terms of real-time infeasibility for high data rate transmission with quality performance. The existing all-optical signal regeneration techniques remain in challenges for its complex design, testing and modeling prospective. The proposed all-optical signal regeneration technique is the new signal r...

GPR system equipment is used to detect embedded objects in the earth’s surface. This system applied a method that is based on the reflection technique of the electromagnetic wave produced by the dipole antenna. To obtain a clear image of the GPR radargram, the output signal of the GPR antenna will be processed using the envelope detector (ED) technique. In this study, the frequency range used in developing GPR system simulation is from 0.07 to 0.08 GHz. The GPR system simulations were designed t...

In this paper, phase sensing technology based optical signal regeneration system is designed and developed for 40 Gb/s optical system. The designed technique has achieved the low bit error rate (BER) and high Q-factor for the long haul optical system of 200 km. In comparison to the existing systems, the proposed technique have achieved the low BER and high Q-factor for long noisy fiber link. In this work, the HNLF configuration based that varies the phase sensing during the optical signal regene...
This study examines the possibility of remotely measuring the cardiac pulse activity of a patient, which could be an alternative technique to the classical method. This type of measurement is non-invasive. However, several limitations may deteriorate the accuracy of the results, including changes in ambient illumination, motion artifacts (MA) and other interferences that may occur through video recording. The paper in hand presents a new approach as a remedy for the aforementioned problem in car...

One of the equipment that can be used in detecting underground objects is the GPR system. This equipment uses an electromagnetic wave reflection technique produced by its antenna. However, the clarity of the GPR radargram image produced by the system is said to depend on the operating frequency of the system. In order to study the effect of the operating frequency on the GPR radargram, this study developed simulations of the GPR system using three operating frequencies to detect the existence of...

The electrical profiles of the renewable polymer graphite (PG) composites upon ultra violet (UV) curing were investigated. Renewable PG films were prepared by mixing with varying weight percent of graphite (with an increment of 5 wt. % of prepared graphite) up to 30 wt.% and crosslinker. Then, the composites solution was slip casted and cured upon stimulated UV irradiation (UV accelerated weathering tester) at different time exposure (up to 1000 hours) was applied. Small changes on the functiona...
