    A novel approach using optical fringe analysis for breast carcinoma detection

    No full text
    Doctor of Philosophy in Microelectronic EngineeringBreast carcinoma is one of the primary cancers diagnosed among woman with 25.1 % accounted of all cancers in women. Recognized methods for breast carcinoma detection and diagnosis include breast self examination (BSE), physical examination, invasive methods such as fine needle aspiration (FNA) and biopsy and non-invasive breast imaging methods such as mammography, ultrasound and magnetic resonance imaging (MRI). However, BSE, CBE, mammography, ultrasound and MRI are not entirely noninvasive as the methods somehow requires physical touches to the breast. Based on the reported previous works, the feasibility of using an optical method is evident as a full non contact and non invasive method, and there is room for vast improvement in using optical methods for early breast carcinoma detection based on surface analysis. Fringe projection techniques are emerging as non-contact tool in optical metrology with applications ranging from 3D Micro-electromechanical systems (MEMS) component measurement, accurate flatness measurement, vibration analysis and biomedical applications for assessment of complex three-dimensional human form. Despite the vast applications in the biomedical field, application of fringe projection in breast carcinoma detection and assessment is notably minimal. Thus, in this work, the usage of a fringe projection rig based on phase shift technique for non-invasive surface metrology analysis of the breast as an adjunct tool for early breast carcinoma detection was done. The fringe projection rig was utilized to analyze the surface changes of the breast due to the presence of breast lump within the breast

    Synthesis and characterization of reduced grahene oxide (rGO) / tips-pentacene composite material for organic thin film transistor (OTFT) sensor platform

    Master of Science in Material EngineeringOrganic thin film transistor (OTFT) has drawn a lot of attention due to their advantages of flexible, transparent, easy to fabricate and cost effective production. The main problem occurred in OTFT was its lower ion mobility but higher Ion/Ioff ratio which could prevent their application for high performance electronic devices. Graphene material displayed an excellent carrier mobility but lower Ion/Ioff ratio. So, the objective of this research was to develop a reduced graphene oxide (rGO)/TIPS-pentacene composite material based OTFT sensor platform to overcome these limitations. Graphene oxide (GO) was synthesized using Tour’s method and chemically reduced using ascorbic acid (LAA), fomamidinesulfinic acid (FAS) and sodium sulphite (Na2SO3). The rGO were characterized using Fourier transforms infrared spectroscopy (FTIR), X-Ray Diffraction (XRD), Thermal Gravimetric Analyzer (TGA), Field emission scanning electron microscopy (FESEM), four point probe and semiconductor parameter analyzer (SPA) to confirm the reduction of rGO. From this characterization, it was found that rGO-FAS was a better reducing agent, which resulted better device performance. For fabrication of OTFT device, polymethylmethacrylate (PMMA) and TIPS-pentacene were deposited on Poly (ethylene terephthalate) (PET) substrate by spin coating method

    A study on atmospheric pressure plasma jet for hospital acquired bacterial inactivation by different working gases with varying flow rate and exposure time

    Master of Science in Biomedical EngineeringAtmospheric Pressure Plasma Jet (APPJ) is ionized gas that is generated at atmospheric pressure and at room temperature, by allowing the gas to flow in a small tube with the higher voltage supplied to the area. Plasma offers many advantages that makes it suitable in various applications, including medicine and sterilization. This research focuses on a cold plasma application, namely APPJ, in the sterilization field. The objective of this study is to establish the plasma for the inactivation of bacteria, to study the microbial inactivation effects of APPJ variables in term of the types of microbes, the types of gases, the various gas flow rates, and the exposure times, to study the optical emission spectrum of the APPJ, and to observe the bacteria after exposure to plasma by high power microscope. In this study, a self-developed APPJ was used to inactivate Acinetobacter baumannii (A.baumannii) and Methicillin-resistant Staphylococcus aureus (MRSA) by using different gases, namely He, He/N, and Ar at various gas flow rates in the range of 300ml/min to 1000ml/min, for 9, 12, 15, and 18 seconds of exposure. After that, the treated samples were transferred to a new agar surface and incubated for 24 hours at 37◦C to observe bacterial growth. The A.baumannii and the MRSA were successfully inactivated by the APPJ. The He plasma inactivated the bacteria more effectively than the other gases. The A.baumannii and the MRSA bacteria were fully inactivated after 9 and 12 seconds, respectively, at the flow rate of 1000ml/min. Ar plasma achieved 0% survival at 9s exposure, however the inactivation of bacteria were not consistent especially for MRSA

    Link to publisher's homepage at http://ijneam.unimap.edu.myThe shoreline is the line that marks the boundary between water and land. Monitoring and analysing shoreline changes is critical because it provides a greater understanding of the shoreline changes as well as the identification of beach conditions. As its usage is more dependable and simpler than the previous technologies used, the use of an Unmanned Aerial Vehicle (UAV) or drone has become a significant technology in coastal engineering, particularly in the research of shoreline changes. The focus of this research is to assess the state of the shoreline at selected beaches, acquire shoreline data, and measure shoreline changes through processed imagery. The flight planning route has been programmed in “Pix4D Capture” application and the drone will capture the image throughout the grid line set. The Pix4d Mapper and Global Mapper software were used to process the data on shoreline changes. From the 19th of October 2020 to the 10th of August 2021, shoreline changes were monitored throughout the one-year period. The changes show that the maximum shoreline evolution is 7.47 m and the minimum shoreline evolution is 0.36 m. The changes in the shoreline were obvious in less than a year, indicating that Pantai Punggur is in a state of erosion
