Artificial neural networks (ANNS) for daily rainfall runoff modelling
(The Institution of Engineers, Malaysia, 2007-09)Rainfall-runoff relationships are among the most complex hydrologic phenomena. Hydrologists have developed conceptual models to simulate runoff but these are composed of a large number of parameters and the interaction is ... -
Distributed model for changes in river peak flow due to land development
(The Institution of Engineers, Malaysia, 2006-03)Land development for new townships, agriculture or recreational areas is almost always accompanied by environmental problems. Some of these are soil erosion, soil fertility degradation, river sedimentation and sometimes ... -
Applications of remote sensing in the monitoring of rice crops
(The Institution of Engineers, Malaysia, 2006-12)Remote sensing, which is the science of acquiring information re g a rding the earth's surface without physical contact, is becoming i n c reasingly important in many fields today. Recently, remote sensing is finding its ... -
Sediment model for natural and man-made channels using general regression neural network
(The Institution of Engineers, Malaysia, 2008-09)This paper presents a new sediment transport model using general regression neural network (GRNN) that are applicable for both natural and man-made channels. GRNN is a supervised network that trains quickly sparse data ... -
Long-term tidal forecasting and hindcasting using QuickTIDE tidal simulation package
(The Institution of Engineers, Malaysia, 2007-06)A tidal simulation package built on MATLAB neural network toolbox with user-friendly graphical user interface (GUI) is presented. The application, named QuickTIDE, is modeled using a back-propagation neural network (BPN) ... -
A model study on retaining wall with reinforced backfill
(The Institution of Engineers, Malaysia, 2007-06)The usefulness of the patented reinforced earth wall of Vidal, where reinforcement is attached with the skin panels, has been proved beyond doubt but under certain circumstances a conventional retaining wall with reinforced ... -
Modeling water balance components in rice field irrigation
(The Institution of Engineers, Malaysia, 2006-12)In this study, a water balance equation approach was applied to the irrigation practiced at the Besut Rice Irrigation Scheme. Each component of the equilibrium equation, where not measured, was modeled using equations ... -
System analysis of efficient production processes for productivity enhancement through productivity balance in injection moulding process
(The Institution of Engineers, Malaysia, 2006-03)The purpose of this paper is to present a study of mathematical model of system analysis of efficient production processes. Its objective is to perform productivity balance calculation based on data obtained from injection ... -
A review on the design criteria of biological aerated filter for COD, ammonia and manganese removal in drinking water treatment
(The Institution of Engineers, Malaysia, 2009-12)The design criteria of biological aerated filter (BAF) were reviewed in order to design an effective process for organic and inorganic contaminants removal in drinking water, particularly, COD and ammonia removal. The ... -
Two dimensional datamodeling and Chebyshev approximation of spline
(The Institution of Engineers, Malaysia, 2006-03)This paper describes the approximation of discrete data using splines. The approximation method is adapted from the Chebyshev approximation. The procedures to find a set of extreme points for incoming discrete data are ... -
Solidification/stabilisation of soil contaminated with metal: A review
(The Institution of Engineers, Malaysia, 2008-09)Solidification/stabilisation (S/S) is generically defined as a chemical and physical alteration technique of reducing the mobility as well as solubility of contaminants in wastes in order to convert them into chemically ... -
