    • Effect of substrate bias in copper sputtering plasma measured by Langmuir Probe 

      Jia Wei, Low; Nafarizal, Nayan; Mohd Zainizan, Sahdan; Mahamad, Abd Kadir; Mohd Khairul, Ahmad; Ali Yeon, Md Shakaff; Ammar, Zakaria; Fathinul Syahir, Ahmad Saad; Ahmad Faizal, Mohd Zain (Trans Tech Publications Inc., 2014-04)
      There are several techniques to deposit the metal oxide thin film such as electron beam evaporator, pulse laser deposition and reactive magnetron sputtering deposition. In this experiment, magnetron sputtering deposition ...

    • Highly selective molecular imprinted polymer (MIP) based sensor array using interdigitated electrode (IDE) platform for detection of mango ripeness 

      Huzein Fahmi, Hawari; Nurul Maisyarah, Samsudin; Ali Yeon, Md Shakaff, Prof. Dr.; Yufridin, Wahab, Dr.; Uda, Hashim, Prof. Dr.; Ammar, Zakaria; Supri, Abdul Ghani, Prof. Madya Dr.; Mohd Noor, Ahmad, Prof. Dr. (Elsevier B.V., 2013)
      Detection of mango ripeness was performed by developing a highly selective molecularly imprinted polymers (MIP) layer combined with interdigitated electrode (IDE) as sensor. Mango volatiles from different week of ripeness ...

    • A hybrid sensing approach for pure and adulterated honey classification 

      Norazian, Subari; Junita, Mohamad Saleh, Dr.; Ali Yeon, Md Shakaff, Prof. Dr.; Ammar, Zakaria (MDPI AG, Basel, Switzerland, 2012-10)
      This paper presents a comparison between data from single modality and fusion methods to classify Tualang honey as pure or adulterated using Linear Discriminant Analysis (LDA) and Principal Component Analysis (PCA) statistical ...

    • Improved Maturity and Ripeness Classifications of Magnifera Indica cv. Harumanis Mangoes through Sensor Fusion of an Electronic Nose and Acoustic Sensor 

      Ammar, Zakaria; Ali Yeon, Md Shakaff, Prof. Dr.; Maz Jamilah, Masnan; Fathinul Syahir, Ahmad Saad; Abdul Hamid, Adom, Prof. Dr.; Mohd Noor, Ahmad, Prof. Dr.; Mahmad Nor, Jaafar, Assoc. Prof. Dr.; Abu Hassan, Abdullah; Latifah Munirah, Kamarudin (MDPI AG, 2012-05-10)
      In recent years, there have been a number of reported studies on the use of non-destructive techniques to evaluate and determine mango maturity and ripeness levels. However, most of these reported works were conducted ...

    • Influence of dissipation power in copper sputtering plasma measured by optical emission spectroscopy 

      Kevin, Low; Nafarizal, Nayan, Prof. Madya Dr.; Mohd Zainizan, Sahdan, Dr.; Abd Kadir, Mahamad, Dr.; Mohd Khairul, Ahmad, Dr.; Ali Yeon, Md Shakaff, Prof. Dr.; Ammar, Zakaria; Fathinul Syahir, Ahmad Sa'ad; Ahmad Faizal, Mohd Zain (Trans Tech Publications, 2014)
      Copper oxide is a low cost material, easy process fabrication and sensitivity to ambient conditions. Therefore, it is a suitable p-type semiconductor oxides material to be used as a gas sensing material. In order to raise ...
