Ground-level ozone is one of the dominant criteria pollutants that contribute to unhealthy days in ambient air measurements throughout Malaysia. In addition to VOCs and NOx, meteorological factors such as insolation and temperature influence the formation of ground-level ozone. For this reason, the relationship between daily maximum temperature and variation of ground-level ozone concentrations using...
An automatic traffic sign detection system detects traffic signs from within images captured by an imaging sensor, and assists the driver to properly operate the vehicle. The idea presented here is through pixel value detection for hazard traffic signs containing red color background, computing in range regions and finally shape matching to choose the most appropriate traffic sign candidates to be...
Background Assisting smoking parents to quit smoking and eliminating the secondhand smoke (SHS) exposure of their children is a global health priority. Engaging healthcare workers in developing countries to address this priority has been a challenge. This study intends to explore issues around current practice related to SHS exposure assessment and counseling and identify barriers to SHS exposure...
Undoped Nanostructured Titanium Dioxide thin film (UN) and Cobalt doped nanostructured (CoDN) TiO2 thin film has successfully prepared using sol-gel method and deposited onto silicon and glass substrate by spin coating technique. Nanostructured TiO2 thin film were prepared at 0.1 M, 0.2 M, 0.3 M and 0.4 M, Co doped TiO2 thin film was prepared with additional of ion Co at 1 at%. The electrical and...
Zinc Oxide (ZnO) thin films were prepared on glass substrates using sol-gel coating method and the effect of annealing temperatures on the ZnO properties were investigated. The Current-Voltage (I-V) measurement shows electrical properties are improved with annealing temperatures. X-ray diffraction (XRD) spectra indicate annealed samples having preferential growth at (002) plane and the structural...
Zinc Oxide (ZnO) is a promising candidate for UV sensing applications because of its direct bandgap energy of 3.37 eV and very sensitive to UV light. In this work, we present the effect of annealing temperature on the electrical and optical properties of nanostructured ZnO for UV sensing applications. The SEM results indicate that the surface morphologies of nanostructured ZnO varies with annealing...
Dietary menu planning is a complicated process that researchers have tried to computerize since the early 1960s. The application of artificial intelligence (AI) techniques to such a process has also been put forward recently. However, the amount of common-sense knowledge involved and the complexity nature of the menu planning activities have yet produced encouraging results. This paper presents our...
