A NUMERICAL SIMULATION OF OPTICAL RECEIVER PERFORMANCE OF WDM SIGNALS IN A PON
Abstract: This work presents MATLAB 7.9 model of wavelength division multiplexed (WDM) communication system for evaluating the performance of optical receiver simulation of WDM-PON (passive optical network). This paper attempts to focus on eliminating the channel internal noise due to number of users at different noise power levels, iterations, values of BER (bit error rate) and error count within time elapsed in seconds. Optical communication systems have good speed, accuracy and …

Initiation of Distress in Asphalt Concrete After Practicing Moisture Damage
Abstract: The moisture damage of asphalt concrete is considered as major type of distress in heavy rainfall environment. In this work, the decline in the initial flexural stiffness of asphalt concrete was monitored after practicing the moisture damage process. The variations were analyzed relative to the control mixture. Asphalt concrete mixtures were created in the laboratory with the optimal binder content. Extra mixtures were also prepared with ±0.5% variation of binder …

Heat Sink-PCM Device for PV Efficiency Improvement
Abstract: This paper is focused on the development of a second stage of a previous work where the PV panel efficiency is improved by using a hybrid system made up of a PCM attached to the rear side of the panel. This evolved stage incorporates a heat sink unit to improve the distribution of the heat removed from the panel; this improvement reduces the elapsed time to reach the steady state …

Devanagari Script Recognition System using Combined Approach
Abstract: We envisioned serving simple technique with novel idea for the newcomers, working in the Devnagari Optical Character Recognition (DOCR) area. In this system, template matching technique and statistical technique is combinely used for the character recognition. Statistical information is considered as a feature of an image and here pixels values are considered as feature to achieve the recognition. The numbers of comparisons are drastically reduced compared to traditional template matching …

Messenger RNA Approach for Identifying Inter-nucleotide Signals using Genomic Sequences
Abstract: The inter-nucleotide signals are a novel way of genomic signal representation of genomic data which is seen to have a discriminatory capability in highlighting the promoter region of gene sequences. The results of applying DFT to in genomic sequence signals that they can discriminate using messenger RNA for identifying inter nucleotide sequences. Genomic Signal Processing (GSP) applications in bioinformatics research have received great attention in recent years, where new effective …

ENERGY LOSSES IN FLOATING OFFSHORE WIND TURBINE WITH VARIABLE WIND DIRECTION
Abstract: The paper analyses the effects of the variation of wind direction onto the performance of a floating offshore wind turbine (FOWT). The evolution of the Cp coefficient is developed as a function of the velocity of the yaw angle correction when realigning the FOWT after a wind direction change. The results are computed for velocities correction of the yaw angle between 1º/min and 5º/min. A maximum drop of the Cp …

Higher Ordered Resonant Periodic Orbits in Perturbed Sun-Mars System
Abstract: In this paper, we have studied interior resonant orbits of higher order in the framework of photo–gravitational restricted three-body problem. The seventh, ninth and eleventh order interior resonant periodic orbits are analyzed for Sun-Mars system. The location, eccentricity and period of resonant orbits are investigated in the perturbed case for a given value of Jacobi constant C. It is observed that for a given order of resonance, a period of …
