In order to deal with more and more serious problem of microwave radiation pollution, palm oil biomass cement based microwave absorber is needed in order to prevent the buildings from the microwave radiation coming from telecommunication towers. This paper describes the capability of palm oil biomass waste from palm oil fuel ash (POFA) as an absorbing material in cement based microwave absorber that...
This paper investigates the capability of oil palm ash paint as green-absorbing material in a way to absorb microwave radiations. The paint is coated on three different wall materials which are elephant board, plywood and cement. The absorb performance of the paint is observed using the simulation result of Computer Simulation Technology (CST) Microwave Studio software. Meanwhile, the exact performance...
Radio frequency (RF) and microwave (MW) radiation are electromagnetic radiation in the frequency ranges 3 kHz – 300 MHz, and 300 MHz – 300 GHz, respectively. While there have been many benefits from the use of RF frequency, people nowadays are concerned that a long-term exposure could affect their body biological system and health. The recent increase in the usage of mobile telephone has raised the...
Cervix cancer is the most common gynecological malignancy and second most common cancer among female in Malaysia after breast cancer. The objective of this study is to extract the size of nucleus and cytoplasm, as well as gray level values of cervical cells from ThinPrep images so that accurate value of those parameters can easily be obtained. An alternative approach of extracting features for Pap...
