To determine the relationship between the two variables, the Chlorophyll (Chl-a) in phytoplanktons around the Bidong Island, Terengganu was estimated using the Sentinel-2 Multispectral Instrument (MSI) running two algorithms - C2RCC and OC3M - between 2015 and 2016. The OC3M algorithm resulted in better Chl-a estimation values with RMSE of 0.05 and MAE of 0.049. The relationship analysis was done using linear regression between OC3M Chl-a and MODIS SST. The regression analysis found that the Chl-a variation in the area was only weakly affected by the SST, with highest negative correlation of -0.2867 in September 2016. Fish sampling in the study area showed that there was significant difference in the diversity of fish species between the years 2015 and 2016. Comparison with Chl-a distribution showed that high species diversity and abundance of fish reduces the amount of...

There is a need to take appropriate preventive measures to reduce the negative impact by carefully monitoring the sprinkles and dispersion particles due to the oil spill movement. An expected oil spill originating from the Resak platform is positioned at 49.1 nautical miles from the Kuala Terengganu shoreline. The Dulang platform, positioned at 69.8 nautical miles from the Kuala Terengganu, can pollute the coastline of the Terengganu and Pahang ecosystems. This study aims; (i) make predictions from the direction of oil particle dispersion and; (ii) engage the ecosystem to determine the effect of an oil spill on a platform around the coastal area. The combination of the Geographic Information System (GIS) and the Oil Spill Trajectory Model (OSTM) has been used to establish the appropriate response to locate the dense area of the slick. The result from the mod...

Therefore, choosing the location for the MPA is a critical step due to the nature of this tool that is prone to cause conflict and has broad impact to local and larger community. The selection processes require many criteria to consider thus this research use Analytical Hierarchy Process (AHP) method in Geographical Information System (GIS) to calculate MPA location. AHP has ability to simplify multidimensional criteria into single dimensional scale and GIS make is easier to analyze wide area. The research is conducted in Pulo Breuh (Breuh Island) Aceh Besar district of Aceh province, Indonesia. There are 6 components to calculate in determining MPA location for this island, the Settlement; Tourist Attraction; River; Aquaculture site; Ferry port and Fishing port, and each of this criterion is depicted into single layer of map based on the distance. The MPA...

Its operating frequency is at 2.4GHz with transmit power of 10.41dBm. Range resolution of the radar is 2.8meters at 53.2MHz signal bandwidth and chirp waveform of 40ms. The radar exploits Doppler principle to acquire the range and velocity information of targets whilst a Moving Target Indicator (MTI) pulse canceller is utilized to filter incoming noise signal. With the use of Chirp periodbandwidth product of Frequency Modulated (FM) waveform and deramping process, the radars' Signal to Noise Ratio (SNR) was improved up to 42dB. The attained maximum range is about 200meters for target with Radar Cross Section (RCS) of 1m 2. The constructed radar is capable to measure speed of moving target at 0.645m/s and above with great accuracy. The radar can detect and determine position of pedestrians with 0.18% percentage error.

Although the shoreline may be mapped accurately from fine spatial resolution imagery, this is an impractical approach for use over large areas. An alternative approach using coarse spatial resolution satellite sensor imagery, addressed here, is to fit a shoreline boundary at sub-pixel scale. This paper investigates the effects of utilizing relatively coarse spatial resolution satellite sensor imagery to produce accurate shoreline maps. For the purposes of this research a 1m spatial resolution IKONOS satellite sensor image was used to define the actual location of the shoreline. This image was degraded to spatial resolutions of 16 m and 32 m, comparable to that of widely used civilian remote sensors. The coarse spatial resolution images derived were used in the evaluation of four methods for shoreline mapping. The conventional method based on hard classification provided an inaccurate and inappropriate representation of the shoreline. Super-resolution methods based on sub-pixel information derived from a soft classification provided accurate and realistic prediction of the shoreline. The most accurate prediction of the shoreline, with RMSE less than 2.1 m and 5.2 m for all the shorelines at 16 m and 32 m spatial resolutions respectively, were derived from a method based on simulated annealing.

Several parameters have been proposed to predict the evolution of the aorta diameter , such as thrombus existence, blood flow velocity, flow rate and shear stress on aortic wall. This article proposes profile of blood flow velocity that moving toward aortic wall (Radial Velocity) that causing presumption that will push up the size of the aortic wall. Data were obtained from 11 patients with Small Abdominal Aortic Aneurysms (SAAA) who had an examination at least 1 to 3 times with an examination every 6 to 12 months (according to the patient). MR Images were acquired on a 3T Imager. Based on the proposed formula to obtain the value of the radial velocity, it can be conclude that the radial velocity value is have the good correlation to the value of the maximum diameter with R=0,736 (where 0,5>R>1).

These environmentally sensitive areas are under intense pressure from natural processes, urban growth, resources development, and pollution. These threats have made the coastal zone a priority for shoreline monitoring programs. This research utilizes multi-temporal satellite imagery to monitor shoreline changes from 1992 to 2009 at Seberang Takir, Terengganu, Malaysia through the use of image processing algorithm and statistical analysis. All the imagery was geo-rectified to the Malaysian Rectified Skew Orthomorphic (MRSO) projection and analysis was done to detect spatially significant areas with erosion and accretion along the shoreline and detect potential sources of the changes. The shoreline was divided into 16 sited and shoreline changes at the sites were determined based on satellite sensor imagery. Preliminary result show erosion occurring near to human...

There are a smaller number of studies that dealt with developing remote-sensing techniques for detecting and mapping different shoreline types (ST) using coarse-resolution imagery. This study examined fuzzy c-means (FCM), wavelet interpolation, and fuzzy maximum likelihood to map shorelines over Seberang Takir (Malaysia) for different STs. These three fuzzy classification methods were applied to simulated IKONOS (with 16-and 32-m spatial resolutions) image covering the four STs. The positional accuracy of shorelines was assessed in terms of root mean square error (RMSE). The visual inspection and RMSE values showed that variations in accuracies were evident, predominantly due to differences in STs; fuzzy algorithm improved the accuracy. FCM can predict shoreline positions with greater accuracy than the other two methods.
