Investigate spectrum-sliced WDM System for FTTH
(Springer-Verlag Berlin Heidelberg, 2011-06-27)
In this paper, we have investigated the performance of spectrumsliced WDM system for FTTH network using NRZ modulation format with 2.5 Gb/s bit rates and 0.4-nm channel spacing. The bit-error-rate (BER) measured against ...
A chaotic neural network based encryption algorithm for MPEG-2 encoded video signal
(Universiti Malaysia Perlis (UniMAP), 2012-02-27)
In this paper, a cipher system based on Chaotic Neural Network (CNN) is used to encrypt and construct a stream
cipher of compressed MPEG-2 video signal. The symmetric CNN cipher algorithm transforms the plaintext
(compressed ...
Proposal: Fundamental study of spectral slicing wavelength division multiplexing (WDM) system
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Since the inception of optical fiber communication in 1974, their transmission capacity has experienced a tremendous increase in the years after. Several technology advances spurred its growth. But its use was kept to long ...
A study of TCP congestion control mechanisms
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
In this paper, the TCP congestion control mechanisms are discussed. There are four intertwined mechanisms defined in the Internet standards track protocol, which are slow start, congestion avoidance, fast retransmit and ...
Modified median filter for noise reduction in Ziehl-Neelsen sputum slide images
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Image filtering is an important approach in the area of digital image processing for noise reduction. The time cost and output image quality in the filtering system are two convention measures in selecting the appropriate ...
A framework for Emmbedded parallel computers
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
High Performance Computing has provided the most interesting platform in the quest to solve high computational problems. Several factors have been identified that can be the focal points for enhancing current computing ...
Design and implementation of fail -recover operation for embedded system based FPGA
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
High speed digital systems are often applied in critical
tasks or in environments where a failure can result in
unacceptable malfunctions or in dangerous situations
for people. This proposal presented Fail-Recover
Operation ...
Image enhancement using white balance technique in Ziehl-Neelsen sputum slide images
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Ziehl-Neelsen stain method is one of the common techniques that are being used to diagnose the tuberculosis (TB) infection. However, due to the manual process of preparing the samples, the image of the slide may not appear ...
TCP SYN flood attack analysis based on payload
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Transmission Control Protocol (TCP) Synchronized (SYN) Flood has become a problem to the network management to defend the network server from being attacked by malicious attackers. The malicious attackers can easily exploit ...
LAN packet acquisition system using ARM based SBC
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Due to computer hardware technologies software developers are more focusing to develop embedded software. LAN packet acquisition system can embed on ARM based embedded Linux based single board computer (SBC). This paper ...
