Deoxyribonucleic Acid or DNA computing has emerged as an interdisciplinary field that draws together chemistry, molecular biology, computer science, and mathematics. From the DNA computing point of view, it has been proven that it is possible to solve weighted graph problems by exploiting some characteristics of DNA such as length, concentration, and(More)
A new readout approach for the Hamiltonian Path Problem (HPP) in DNA computing based on the real-time polymerase chain reaction (PCR) is investigated. Several types of fluorescent probes and detection mechanisms are currently employed in real-time PCR, including SYBR Green, molecular beacons, and hybridization probes. In this study, real-time amplification(More)
Image difference operation is frequently used in automated printed circuit board (PCB) inspection system as well as in many other image processing applications. The previously proposed wavelet-based PCB inspection approach also incorporated the point-to-point image difference operation as part of its algorithm. Unfortunately, during the implementation, this(More)
This paper presents the implementation of moment invariants; with respect to centroid point obtained from frontal mugshot images, for thermal-based face identification system. Initially, seeded region growing method is applied for background filtering. Sequentially, the system decomposes a background filtered thermal image into 4 thermal regions via(More)
Previously, direct-proportional length-based DNA computing (DPLB-DNAC) for solving weighted graph problems has been reported. The proposed DPLB-DNAC has been successfully applied to solve the shortest path problem, which is an instance of weighted graph problems. The design and development of DPLB-DNAC is important in order to extend the capability of DNA(More)
This paper discussed the implementation ideas and experimental procedures to solve an engineering related combinatorial problem using DNA computing approach. An elevator scheduling problem is chosen as a benchmark where all the elevator traveled paths are represented by DNA sequence of specific length that represent the elevator's traveling time in a(More)
This paper presents the extension of our previous work on moment invariants with respect to centroid point (obtained from frontal mugs hot images) for thermal-based face identification system. In previous work, seeded region growing method was applied for background filtering. Sequentially, the system decomposes a background filtered thermal image into 4(More)
