    The Development of Bird Monitoring System By using optical and images processing techniques.
    (2013)
    Chow Jeng, Wong
    Pemerhatian dan pengiraan penghijrahan bilangan burung pemangsa telah dilakukan sejak zaman purba. Tujuan usaha ini telah ditukar dari ingin memburu burung migrasi ini hingga sekarang pemuliharaannya. Teknik mengira manual biasanya digunakan, tetapi kejituanannya adalah diraguragukan. Kejituan pengiraan juga berbeza-beza dari seorang pengira kepada pengira-pengira lain. Penyelidikan ini adalah untuk meningkatkan kejituan pengiraan bilangan burung pemangsa yang berhijrah. Observation and counting the number of migratory raptor has been done since ancient times. The purpose of this effort was changed from hunting the migratory raptor to now conservation of the migratory raptor. Manual counting technique is commonly used, but the counting accuracy was doubt. The accuracy of the counting also varies from one to the other people of counter. The purpose of this research is to increase the accuracy for counting the number of migratory raptor.

    The development of an algorithm and a model through image processing and remote sensing techniques for assessing environmental impacts of routine carbon footprint in Peninsular Malaysia.
    (2015)
    Mat Jafri, Mohd. Zubir
    This research develope the prediction models which analyze and compute the CO2 emission in Malaysia. Each prediction model for C02 emission is analyzed based on three main groups which is transportation, electricity production and consumption as well as residential and industry. The prediction models was generated using data obtained from World Bank Open Data. Partial least square and best subset method were used to remove irrelevant data and followed by multi linear regression to produce the prediction models.

    X-ray Structural characterization of bioactive compounds from medicinalplants : Premna Obtusifolia and Cratoxylum Formosum ssp. Pruniflorum.
    (2013)
    Ibrahim, Abdul Razak
    Single crystal X-ray diffraction offers a complete approach to structural analysis. X-ray diffraction is the Only technique which provides the complete three dimensional structures of the chemical compounds. The formation of supramolecular arrangement in crystal structures is indeed important not just for the Construction of larger structures, this non-covalent bond assisted arrangement possess unique physical And chemical properties. In this research, the molecular and crystal structure of the medicinal plants Which are Premna obtusifojia (Verbenaceae) and Cratoxy/um formosum ssp. Pruniflorum are studied. Apart from this, other medicinally important compounds are also synthesized and their crystal structures Are also examined. Belauan sinar-X hablur tunggal memberikan pendekatan yang lengkap untuk analisis struktur. belauan sinar-X adalah satu-satunya teknik yang memberikan struktur tiga dimensi yang lengkap sesuatu sebatian. Pembentukan susunan supramolekul dalam struktur hablur sememangnya penting bukan hanya untuk pembinaan struktur besar, susunan yang dibantu oleh ikatan tak kovalen memiliki ciri-ciri fizikal dan kinia yang unik. Dalam penyelidikan ini, struktur molekul dan hablur tumbuhan berubat iaitu Premna obtusifolia (Verbenaceae) dan Cratoxylum formosum ssp. pruniflorum telah dikaji.

    Surface phonon polariton resonance modulation in wurtzite III-nitride semiconductor system via modification of surface structure and formation of alloy structure.
    (2015)
    Ng, Sha Shiong
    Surface phonon polariton (SPhP) characteristics of wurtzite III-nitride semiconductors have received considerable attention from the scientific research community. This is attributed to its unique resonant characteristics possess a great potential to be used for various important technological applications.

    A study of the solutions of The Yang-Mills-Higgs theory.
    (2005)
    Teh, Rosy Chooi Gim
    In our project, we have constructed exact static multimonopole-antimonopole solutions and their anti-configurations of the SU(2) Yang-Mills-Higgs (YMH) field theory.
