Degradation and orientation of collagen / Saiful Bahri Mohd Yasin
Get PDFThe degradation of collagen properties such as UV light exposure, solvent effect and pH affect was investigated. At initially, Difference Scanning Calorimetric (DSC) was used to investigate the temperature profile of raw collagen. Then, collagen was diluted in water, a mild acetic acid and hydrochloric acid to form collagen film by bulk film into petri dish and thin film on glass slide as well as Polytetrafluorethylene (PTFE) coated glass slide. The film was exposed to Ultraviolet light to investigate the degradation of the molecular structure by using Fourier Transform Infrared Spectrometer (FTIR) spectrum. The Polarized Microscope (PLM) was utilized to observe the orientation of the collagen on glass and Polytetrafluorethylene (PTFE) coated glass slide. The finding for these studies was employed for application of thin film used for medical purposes

Sinusoidal pulse width modulation (SPWM) on cascaded H-bridge (CHB) converter harmonic analysis
No full textWith the vast range of power electronic applications in modern engineering world, the need for better control of electronic devices is highly important. The control of power electronic converter is necessary in delivering power sourced from either conventional fossil fuel or renewable energy sources. Harmonic analysis in these power electronic converters can improve the necessary power needed, especially in reduction of power losses. The paper analyses the harmonic conditions by looking into total harmonic distortion (THD) in a three-level cascaded H-bridge (CHB) power converter. Fast Fourier Transform (FFT) waveform analysis will be used to observe the output waveforms’ performances. THD analysis and FFT will determine the amount of power that can be transferred. The CHB power converter can be used in devices such as static compensator (STATCOM), unified power factor compensator (UPFC) and other compensating devices in a power system. The THD & FFT analyses will be done using MATLAB/Simulink® software.<br/
Factor affecting Gross Domestic Product (GDP) in Malaysia economy / Nur Shafiqa Saiful Bahri
Get PDFGrowth of the Gross Domestic Product (GDP) has always been considered as a contemporary subject that many researchers have studied. Previous research has linked a variety of factors to economic growth fluctuations in varied degrees. Inconsistent GDP per capita growth within a country will result in a higher incidence of poverty, as well as stymie advances in health, education, crime, and economic growth. The elements that contribute to GDP growth are quite important in preventing socio-political instability. In this study, we will research the Gross Domestic Product (GDP) in Malaysia with these factors which are inflation, Foreign Direct Investment (FDI) and Female Labor Force. Annual time series data for the 1999 to 2019 periods, the Ordinary Least Square Method (OLS), T-test, F-test and Coefficient of Determination are used for the analysis
An interchangeable turning sprue bushing (ITSB) system in a family mould / Saiful Bahri Mohd Yasin
No full textA family mould consists of different shape of cavities used, while a multi cavity mould contains same shape of cavities to create injection products. The combinations of these features create a new family mould which is beneficial for the manufacturing cost and time reduction in injection moulding process. However, the main problem of the conventional family mould is the different cavity volume, led to an imbalance of melt filling behaviour. There are many successful family mould modifications which enabled a balance of melt filling such as an artificial balance runner system, runner shut-off system and variable runner system. Nevertheless, the inconsistencies of the melt filling behaviour in these family moulds are yet to be resolved especially when they are utilized in high mass production. Hence, the idea of an interchangeable turning sprue bushing (ITSB) insert was proposed in this study in order to overcome the imbalance of melt filling behaviour. The key for rotating ITSB insert was designed in three stages prior to a final ITSB design. The two chosen product geometry utilized were tensile and flexural test pieces, which were designed with the support of CAE analysis to obtain a favourable feeding system. With the incorporation of ITSB insert at the layout centre, the melt was able to shift in accordance to ITSB insert rotation. This allows filling of the tensile and flexural cavities during moulding at different times and different processing conditions, which resulted in melt filling balance behaviour. The optimization of the injection moulding process such as packing pressure, injection speed and holding time were successfully conducted through Scientific moulding analysis. The efficiency of the ITSB design and its consistency during production were successfully measured from the mass and wall thicknesses data during pilot production. In conclusion, ITSB insert was found to be a favourable optional design that can be considered for injection mould industry in order to produce multi design products

Determinant of financial performance for family takaful in Malaysian industry / Intan Nur Syafinaz Saiful Bahri
Get PDFMalaysia's Takaful industry is a developing rapidly since the first Takaful Company which is Syarikat Takaful Malaysia was established in 1985. Since year 2005 until 2010, the Malaysian Takaful has been experiencing the increasing and Family Takaful business shows the positive growth. The aim of this study is to analyze the factor that influencing financial performance of Family Takaful business. This study is limited to focus in 8 years period. Financial data has been collected on yearly basis from year 2003 until year 2010. 8 Takaful operators out of 12 has become as a sample. Data analysis has been done by using Eviews program. The data collected was analysed by using a basic statistical techniques which is Multiple Linear Regression. The result shows that the Company Size has a significance negative relationship with the financial performance of Malaysian Family Takaful. Meanwhile, Liquidity and Underwriting Risk have a significant positive relationship with the financial performance of Malaysian Family Takaful
