Estimation of missing values in air pollution data using single imputation techniques
(Science Society of Thailand, 2008)Air pollution data obtained using automated machines often contain missing values which can cause bias due to systematic differences between observed and unobserved data. We used interpolation and mean imputation techniques ... -
Climate augmentation of erythemal UV-B radiation dose damage in the tropics and global change
(Indian Academy of Sciences, 2007-12-10)Skin cancer (UV carcinogenesis) causing erythemal solar ultraviolet-B (UV-B) radiation dosages received at tropical latitudes are about five times higher compared to mid-latitudes. The tropical environment also experiences ... -
Comparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement Production
(Science Publications, 2007)Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of ... -
Risk assessment study for storage explosive
(Science Publications, 2006)In Malaysia, there has been rapidly increasing usage in amount of explosives due to widely expansion in quarrying and mining industries. The explosives are usually stored in the storage where the safety precaution had given ... -
Comparative Study of Clinker’s Transformation at Different Temperature Zone During Cement Production
(Science Publications, 2007)Chemical composition analysis using x-ray fluorescence is one of the important quality analysis for examining of cement and widely used in cement industries for a long time as a tool to estimate phase composition. X-ray ...
