The Replacement of Missing Values of Continous Air Pollution Monitoring Data using Mean Top Bottom Imputation technique
(Kolej Universiti Kejuruteraan Utara Malaysia, 2006)
Air pollutants data such as PM10 carbon monoxide, sulphur dioxide and ozone concentration were obtained from automated monitoring stations. These data usually contain missing values that can cause bias due to systematic ...
Concrete Ceramic Waste Slab (CCWS)
(Kolej Universiti Kejuruteraan Utara Malaysia, 2006)
The main focus of this research is to study the strength of concrete with ceramic waste as coarse aggregate. The source of ceramic waste are obtained from industrial in Malaysia. Presently, in ceramics industries the ...
Estimation of missing values for air pollution data using Interpolation technique
(Universiti Malaysia Perlis, 2006)
Air pollution data such as PM10, sulphur dioxide, ozone and carbon monoxide are usually obtained using automated machines located at different sites. These are usually due to mechanical failure, routine
maintenance, changes ...
Concrete Ceramic Waste Slab (CCWS)
(Malaysian Invention & Design Society (MINDS), 2006-05-19)
Concrete Ceramic Waste Slab (CCWS) was fabricated by mixing the composition of cement and ceramic wastes. The ceramic wastes will act as coarse aggregates in the mixture. This slab can be used as landscape products such ...
