Instead of employing typical towing models such as single and symmetrical bridle towline models, an asymmetrical bridle towline configuration is then proposed to improve the ship towing performance during operation. This thesis presents Computational Fluid Dynamics (CFD) analysis on the asymmetrical bridle towline model with respect to its effect on course stability and seakeeping performance of the ship towing system in calm water and waves, respectively. Several towing parameters such as various towing angles, towing speeds and towline lengths have been taken into accounts in the simulation. Here, the course stability performance of the towed barge has been analysed in three degrees-of-freedom i.e., surge sway and yaw motions. Meanwhile, the seakeeping characteristic has been assessed at various wavelengths and wave directions involving five degrees-of-freedom i.e., surge, sway, yaw, heave and pitch motions. 2020-01-01T00:00:00Z http://umt-ir.umt.edu.my:8080/handle/123456789/11728 Title: Detection of aquatic pollutants using luminescent bactteria Authors: Aty Atiqah Muhassan Abstract: Nowadays, luminescent bacteria as a sensing organism to detect the aquatic pollutants have been widely used. In this study, luminescent bacteria were identified and the effect of different concentrations of pollutants towards the density of luminescent bacteria was carried out. The luminescent bacteria were isolated from the ink of the squids. Then, the Gram staining was done to observe the shape of the luminescent bacteria. The bacteria were identified using VITEK. Besides that, the bacteria were tested with different NaCl concentration (0, 1, 2, 3, 4 and 5 % (w/v)) and at temperature (4, 26, 28, 37 and 40 ° C). Then, toxicity test was carried out with 1.5 ml of toxicants Cd, Zn Cb, HgS04, Pb(N03)2, diazinon and malathion (2, 4, 6, 8 and 10 ppm) were added to 1.5 ml of bacterial suspension in a cuvette. As for control, 1.5 ml of saline solution was added to 1.5 ml of bacterial suspensions. 2014-01-01T00:00:00Z http://umt-ir.umt.edu.my:8080/handle/123456789/11570 Title: Remote estimation of sea surface salinity (SSS) from satellite-derived cdom in coastal watrer of Terengganu Authors: Nur Farhana Md Zahair Abstract: This study focuses on empirical closure to the estimation of sea surface salinity (SSS) by using remote sensing of ocean colour. There are two types of important relationship of water optical properties. The first includes the understanding of characteristics of coloured dissolved organic matter (CDOM) along the conservative mixing in salinity gradient. The second one is the relationship between CDOM and water-leaving radiance (upwelling and downwelling radiance). Based on the analysis that we have conducted using statistical analysis, the best CDOM absorption in ultra­ violet wavelength such as 350nm and 380nm can be estimated using blue green ratio as Rrs (412/547) with value ofR 2 = 0.9018. Next, the seasonal dynamic of salinity in coastal water area is determined from satellite ocean colour. During wet and well­ mixed season (Northeast Monsoon) CDOM was almost mixing up well with salinity but acted vice versa during the dry season (Southwest Monsoon). With these results, CDOM and salinity can be estimated by satellite ocean colour as well. 2017-01-01T00:00:00Z
