The performance of dual diffuser modulation using wavelength filtrate detection for free space optics in the presence of rain consequence
No full textMaster of Science in Communication EngineeringFree space optics (FSO) is one of the effective solutions to the ever growing needs of high speed data transfer. It offers unlicensed, higher speed with unlimited bandwidth as well as provides an excellent security. However, it is sensitive to local weather conditions which results to the inconsiderable loss of signal power over the communication path. To the fact, the quality of the FSO links are mainly affected by rain attenuation especially in a tropical environment. The conventional modulation of FSO system increases the error rate and produces low power received in situation of bad weather. Besides that, the existing detection degrades the received signal and not properly operated. Hence, in order to cater this problem, the proposed detection namely Wavelength Filtrate Detection has been developed to enhance the performance of FSO system. The proposed detection is based on the function of Fibre Bragg Grating which is capable to optimise the filter wavelength. In this research, the collection of rainfall data in year 2015 is provided by Malaysia Meteorological Department which covers region in Chuping, Perlis. From this data, a depth analysis of rain attenuation by using mathematical equation of power law has been carried out which results to the maximum rain attenuation of 13dB/km. This value is categorized under heavy rain condition. Then, the analysis is continued with the comparison between conventional modulation technique On Off Keying (OOK) and Dual Diffuser Modulation (DDM). Two types of analysis are done which are theoretical and simulation to prove that DDM technique enhances the performance of FSO system due to the adverse weather condition. The analysis continues with comparison between existing detection and Wavelength Filtrate Detection. The DDM technique is selected as the main modulation in this research because it supports 0.12km range of transceiver and improves signal received approximately 4dBm from the mathematical analysis. Also, the eye pattern in 0.5km range shows DDM technique is widely open with better BER 8.10×10-7 compares to OOK technique which is 6.51×10-4 and results to the higher loss of signal. Furthermore, this technique also supports high data rate up to 10Gbps. The problem occur in DDM technique is on the detection stage. The detection needs to be improved to avoid high signal losses when adverse weather condition occurs. To overcome this issue, Wavelength Filtrate Detection has been developed and it shows the improvement of 21% magnitude of BER as well as increase the power received up to 6dBm. As conclusion, the combination of DDM technique and Wavelength Filtrate Detection (WFD) have increase the performance of FSO system and capable to transmit high capacity of data in a situation of adverse weather condition
Turnover intention among operators in electrical and electronic (E&E) sub-sector
No full textMaster of Science in ManagementHigh employee turnover rate in Malaysia’s manufacturing industry has become an important issue that needs to be discussed because it leads to serious problems in terms of operations and financial consequences such as recruiting, selecting and training of new employees. Employee turnover may also affect the company productivity and performance. In Malaysia, the overall number of voluntary turnover is 7,070 employees in year 2016. A total of 8400 employee turnover in manufacturing sector and 3556 total operator’s turnover in year 2015. The study aims to determine the role of job satisfaction, organizational commitment, emotional intelligence, work-life balance and organizational culture that lead towards turnover intention. The total population of manufacturing operators in year 2015 were about 1,622,400 in Peninsular Malaysia. Data were collected from the highest operators in three states from Malaysia which are Selangor, Johor and Pulau Pinang and the research represents one company from the three states. Based on the formula of Krejcie and Morgan (1970), the sample size is 384 employees. A self-administered questionnaire will be used to collect information from the respondents are machine operators. The instruments adapted from Price and Mueller in 1981 (Turnover Intention), Minnesota Satisfaction Questionnaire (MSQ) short form Weiss, Dawis, England, & Lofquist in 1967 (Job Satisfaction), Allen and Meyer in 1991 (Organizational Commitment), Goleman in 1998 (Emotional Intelligence), Sumaiti in 2010 (Work-Life Balance) and Hofstede in 1984 (Organizational Culture). The data will be analyzed by using the Statistical Package for Social Sciences (SPSS). Multiple regression analysis will be used to test the research hypothesis. The findings support the hypothesis that job satisfaction, organizational commitment, work-life balance and organizational culture were significantly negative towards turnover intention. Besides that, emotional intelligence was found to be non-significant related to turnover intention. Based on the findings of the study, several recommendations have been put forward at the end of the report
