    Analisis Kekukuhan Teori Okun Dan Philips Bagi Negara Asia Terpilih
    (Universiti Malaysia Terengganu, 2014) Ang Syh Han
    Ekonomi rantau Asia telah mengalami pertumbuhan pesat dalam beberapa dekad yang lalu, akan tetapi isu pengangguran dan kadar inflasi masih tidak mampu di kawal oleh pihak kerajaan menggunakan dasar fiskal dan monetari. Isu ini boleh diperjelaskan menggunakan teori tradisional Okun dan Phillips yang menterjemahkan hubungan negatif di antara kadar pertumbuhan ekonomi dan pengangguran; dan hubungan antara pengangguran dan kadar inflasi. Kajian ini dilaksanakan bertujuan untuk menganalisis hubungan kointegrasi dan penyebab menggunakan teori Okun dan Philips yang melibatkan negara maju dan negara membangun Asia seperti Indonesia, Malaysia, Singapura, Thailand, Jepun dan Korea Selatan menggunakan data siri masa tahunan sepanjang tempoh 1980-2010. Terdapat tiga teknik yang penting diambil kira dalam kajian ini untuk penganggaran data siri masa. Pertama, mengenal pasti tahap kepegunan menggunakan pendekatan tradisional dan moden menggunakan kesan perubahan struktur. Kedua, mengenal pasti hubungan kointegrasi menggunakan kerangka jangka masa panjang dan pendek. Ketiga, kajian ini menggunakan ujian penyebab untuk mengesan hubungan penyebab antara pemboleh ubah kajian. Keputusan keseluruhan kajian ini tidak seimbang dan bertentangan dengan hukum Okun dan Philips bagi beberapa negara kajian. Sehubungan itu, untuk mengimbangi pengangguran, inflasi dan pertumbuhan ekonomi, para pembuat dasar harus menilai isu ini dan menganalisis secara kolektif menyebabkan pengangguran dan tidak semata-mata fokus terhadap penetapan teori Okun dan Philips setiap masa.

    Analisis penggunaan dadah secara suntikan di kalangan pesakit HIV-TB
    (Terengganu: Universiti Malaysia Terengganu, 2014-01) Nurul Syahida Abdul Rahman
    Human Immunodeficiency Virus (HIV) merupakan penyakit yang berjangkit yang semakin meningkat dari setahun ke setahun. Virus HIV ini, boleh menjangkiti manusia melalui beberapa cara seperti hubungan seks bebas (secara heteroseksual atau secara homoseksual), jangkitan menerusi aliran darah yang tercemar seperti daripada ibu ke anak sebelum kelahiran, semasa kelahiran, penyusuan susu ibu terhadap anak dan perkongsian peralatan seperti jarum suntikan dadah. Oleh itu, satu kajian telah dijalankan untuk menentukan faktor-faktor yang berisiko yang menyumbang kepada jangkitan TB terhadap pesakit HIV positif melalui penggunaan dadah suntikan (IDU) di negeri Kelantan. Kajian ini menggunakan Model Regresi Logistik dan membuat Pemodelan Persamaan Berstruktur. Sampel kajian yang digunakan dalam kajian ini ialah sebanyak 176 pesakit HIV-TB yang menggunakan IDU dan tanpa IDU yang diperolehi dari Unit Rekod Perubatan Hospital Universiti Sains Malaysia (HUSM) Kubang Kerian Kota Bharu Kelantan.

    The extension of log-aesthetic planar and space curves
    (Terengganu: Universiti Malaysia Terengganu, 2013-10) Yee, Lye Pui
    Generalized Log-Aesthetic Curve (GLAC) is a high quality curve which has been enhanced from Log-Aesthetic Curve (LAC) and Generalized Cornu Spiral (GCS). LAC is synthesized from linear Logarithmic Curvature Graph (LCG), whereas GLAC can produced linear LCG gradient function. The first part of this research is dedicated to formulating offsets of LAC and the investigation of its evolutes which can be utilized to prevent cusps in LAC offset. The second part extends GLAC from planar curve to space curve and the resultant curve is denoted as Generalize Log- Aesthetic Space Curve (GLASC). GLASC is formulated by first constructing torsion profile similar to curvature profile in GLAC. It is then solved both curvature and torsion profile together with initial values in the form of Frenet-Serret frame. The final contribution of this thesis is the modification of GLAC formulation to control the curvature at the endpoints for a given length.

    A framework of ensemble artificial neural networks model for classification of large datasets
    (Terengganu: Universiti Malaysia Terengganu, 2014-07) Mumtazimah Mohamad
    Large datasets related tasks are a great challenge for applications that involve massive amounts of data with high dimensional spaces. hence have gained considerable attention in academic research. Due to its enormous size. the datasets poses a more complex problem especially in classification tasks where the datasets have different characteristics. Currently, most machine learning algorithms are able to deal with small to medium sizes of datasets with the use of single memory computer. However, classification of large datasets with the respective algorithms is impractical since it could reduce computer performance and is size-limited for a single processor with one memory.

    Indeks kecekapan buruh menggunakan analisi sempadan stokastik
    (Terengganu: Universiti Malaysia Terengganu, 2015-04) Ariz Shafiq Bin Hussein
    The labour institution of a nation plays an important role in developing a strong economic performance. However, the question on the degree of its efficiency remains unanswered. The purpose of this study is to determine an efficiency index so-called the Labour Efficiency Index (LEI) in an attempt to answer the highlighted question. Firstly, the index formula employed in various index such as the Consumer Price Index (CPI) and the Human Development Index (HDI) were used to produce two types of the index namely Fixed Base and Chained Base. Then, these index values were combined with the technical efficiency component, 𝑢 in the Stochastic Frontier Analysis (SFA) to produce the desired LEI index. The variables used in the SFA and the index model can be classified into seven dimensions called the output, labour force supply, participation and unemployment rate, level of education, capital, opportunity, and security and threat.

    Integration of interval type-2 fuzzy saw and interval type-2 fuzzy topsis ambulance location selection
    (Terengganu: Universiti Malaysia Terengganu, 2015-04) C.W.Rabiatul Adawitah C.W. Kamal
    Nowadays, Multi Criteria Decision Making (MCDM) methods are widely utilized and known as effective tools in solving real world problems. Various MCDM methods have been implemented in solving diverse applications of decision problems. One of the MCDM methods is additive weighting-based method. Unfortunately, this method is not always applicable due to the limitations in computational reliability and its applications are not-well received by many MCDM enthusiasts. The method is extended to Fuzzy Simple Additive Weighting (Fuzzy SAW)thanks to the development of fuzzy set theory. Fuzzy SAW utilized fuzzy numbers rather than crisp numbers.Nevertheless, type-1 fuzzy set is weak in handling uncertainty compared to Interval Type-2 Fuzzy Set (IT2 FS).

Unfortunately, this method is not always applicable due to the limitations in computational reliability and its applications are not-well received by many MCDM enthusiasts. The method is extended to Fuzzy Simple Additive Weighting (Fuzzy SAW) thanks to the development of fuzzy set theory. Fuzzy SAW utilized fuzzy numbers rather than crisp numbers. Nevertheless, type-1 fuzzy set is weak in handling uncertainty compared to Interval Type-2 Fuzzy Set (IT2 FS). Differently from the typical Fuzzy SAW, which directly utilized trapezoidal type-1 fuzzy numbers, IT2 FS introduced to the Fuzzy SAW to enhance judgments in the fuzzy decision making environment. IT2 FS is more sensitive in handling uncertain information or data. Besides, in this study, Interval Type-2 Fuzzy Simple Additive ii Weighting (IT2 Fuzzy SAW) method is integrate with Interval Type-2 Fuzzy Technique for Order Preference by Similarity to Ideal Solution (IT2 Fuzzy TOPSIS) method to handle fuzzy multiple criteria decision making problems based on IT2 FSs.
