Pretreatment of reverse osmosis (RO) feed water high mineral scaling propensity was evaluated with respect to downstream RO membrane scaling, for two different pretreatment configurations. The schemes included (i) media sand filtration, followed by a hydrocyclone (HC) and (ii) hydrocyclone, microfilter, UF module, where both configurations mesh screens added protection. first configuration redu...

The Artificial Neural Network (ANN) is a powerful data-driven model that can capture and represent both linear and non-linear relationships between input and output data. Hence, ANNs have been widely used for the prediction and forecasting of water quality variables, to treat the uncertainty of contaminant source, and nonlinearity of water quality data. However, the initial weight parameter pro...

This 24 months research topic was an industrial driven project jointly conducted by RSAF-Defence Science & Technology Agency, NTU and Pratt & Whitney (PWA)United Technology Research Centre. The first phase was held in PWA mainly on field investigation of stall flutter in fan blades through the RSAF’s On-Job-Training Programme. The second phase was held in NTU for code development in simulation ...

In this research, the water turbidity measurement tool based on Arduino Uno has been designed and built using phototransistors infrared LEDs. This measuring instrument consists of a series sensors, as process, LCD I2C value viewer, Micro SD data storage, RTC timer. study used two samples with various concentrations. The sample used, namely distilled plus impurities in form soil ash. is still 10...

Abstract Access to clean drinking water is a major issue in many regions of the world, particularly areas where groundwater scarce. This study aims at determining quality two lakes. Some parameters this investigation were found be above WHO limit, while most within limit. For instance, average value electrical conductivity Hanna Lake was 537.4 μS/cm, it 758.9 μS/cm Spin Karez, which limits (&am...

This paper explores the relationships between noncooperative bargaining games and the consistent value for non-transferable utility (NTU) cooperative games. A dynamic approach to the consistent value for NTU games is introduced: the consistent vector field. The main contribution of the paper is to show that the consistent field is intimately related to the concept of subgame perfection for fini...
