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 ...
TCP Vegas’ adaptive CWND in wireless IPv4 and IPv6 networks
(Universiti Malaysia Perlis (UniMAP), 2012-02-27)
In a network, TCP sends burst of data during its
initial state due to the aggressive increase of congestion window
(CWND) size. The aggressive increase in congestion window size
causes traffic overload. In our work, we ...
Mechanomyography sensor development, related signal processing, and applications: A systematic review
(IEEE Conference Publications, 2013)
Mechanomyography (MMG) is extensively used in the research of sensor development, signal processing, characterization of muscle activity, development of prosthesis and/or switch control, diagnosis of neuromuscular disorders, ...
Classification of driver drowsiness level using wireless EEG
(Przegląd Elektrotechniczny, 2013)
In this work, wireless Electroencephalogram (EEG) signals are used to classify the driver drowsiness levels (neutral, drowsy, high drowsy and sleep stage1) based on Discrete Wavelet Packet Transform (DWPT). Two statistical ...
Blind image Steganography scheme using speeded-up robust features technique
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
Steganography, which means “covered writing” in Greek, is the art and science of
invisible communication. It is employed in various useful applications, e.g., copyright control of
materials, companies‟ safe circulation ...
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 ...
Channels estimation in OFDM system on block-type and comb-type pilot arrangement
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
In orthogonal frequency division multiplexing (OFDM) systems over time-varying and frequency-selective fading channel, channel estimation and tracking is generally carried out by transmitting known pilot symbols in given ...
The use of openCV in Traffic Surveillance System (TSS)
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Due to the increase of traffic accidents over the last few years; the development of surveillance systems has increasing attention. The use of the video cameras is one solution to solve the traffic problems, Smart cameras ...
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 ...
