The presence of hydrogen sulfide and chloride in oil and gas production environments can induce deterioration of the passive film, leading to pitting corrosion of stainless steel. In this research, localized behavior of stainless‐steel type 316 L was studied in highly hydrogen sulfide and chloride environment. The environmental condition was setting up using NACE TM0177 Solution A at different partial...
This improving technique based on combining an Iterative Back Projection (IBP) super resolution method with Anisotropic Diffusion (AD) technique for overcoming IBP weaknesses. The IBP has specialty to remove a reconstruction error and blurry effect iteratively manner in image registration place. However, it has a weakness from avoiding result image from chessboard effect and lost high frequency information...
A progressive advancement in biosensors and wireless technology are the major contributors to the realization of continuous remote health monitoring system (RHMS). Wireless Body Area Network (WBAN) is part of this technology due to the deployment of multiple sensors such as Electrocardiogram (ECG) to collect vital body signals for processing and diagnosis. Among the benefits offered by this technology...
Smart Airfield Lighting System (SALS) offers smart airport runway lighting management capabilities based on the ARM 7 Core M3 processors. SALS provide a simple mechanism of switching ON the airfield ground light system whenever the sensors detect the motion of inbound and outbound aircraft coming towards and depart from the airport runway. It provides smart ground lighting system to help improve the...
Cascade-Forward Neural Network (CFNN) performance is explored in this paper for blood stain image analysis. The blood stain images of various size, shape and impact angles are captured through experimentation. Each blood stain in the image is first detected using sobel edge detector. After the image has been thresholded and the noise removed, geometric properties of the blood drop is measured with...
Orthogonal frequency division multiplexing (OFDM) is a promising modulation technique for transmitting large amounts of digital data through radio waves. One major drawback in OFDM communication is peak-to-average power ratio (PAPR). Mainly because of the nonlinearity of the high power amplifier, these results in high out-of-band radiation, inter-carrier interference, and bit error rate performance...
In this paper, a hybrid framework of compressed and encrypted video signal transmission over wireless channel has been designed and implemented. Chaos theory property has been combined with artificial neural network to construct a cipher algorithm called a Chaotic Neural Network (CNN). This algorithm has been embedded and integrated inside MPEG-2 video codec standard to transform the plaintext (compressed...
This research paper implements a 3D tetrahedral meshing frequency solver to simulate the electromagnetic effect of triangular tip (TrT) and tapered tip (TaT) added to a circular split gap. Behavior of circular rings placed inside a standard WR159 waveguide with preference to the conventional circular split ring was modelled. TrT and TaT structures optimization and validation was made using five well...
Peak-to-Average Power Ratio (PAPR) reduction is an attractive research topic among the OFDM transmission research communities. Partial Transmit Sequence (PTS) has been a promising candidate out of the proposed PAPR reduction techniques without any distortion. In any PTS system, partitioning of the OFDM frame into disjoint sub-blocks is a crucial step. Adjacent partitioning (AP) is a rather simple...
The emergence of Wireless Sensor Networks (WSNs) have introduced a new research area known as Body Sensor Networks (BSNs) that hold great promises to facilitate various pervasive monitoring services ranging from home automation, to remote healthcare and military surveillance. The performance of this resource-constrained network, is however, highly restricted by its error-prone characteristic, resulting...
Wireless mobility seems to be transforming the communication industry, shifting the momentum from Internet access to broadband wireless access. This technology-shifting has been expected to provide a better communication services in return. The ability to transfer communication at extremely high speeds and the ability to stay connected during a fast movement speed should always be applicable for the...
While witnessing the rapid development in the world of wireless communication, it is highly expected that the next generation of wireless network to be quickly adapt with the high Quality of Service (QoS) requirements and demands from mobile wireless users especially in real time and multimedia applications. Mobile IPv6 has been declared to be unsuitable for managing the mobility of end users running...
