Passenger Rail Service Comfortability in Kuala Lumpur Urban Transit System
Rail transit transportation system is among the public transportation network in 
Kuala Lumpur City. Some important elements in establishing this system are ticket price, 
operation cost, maintenance implications, service quality and passenger’s comfortability. The 
level of passenger’s comfortability in the coach is important to be considered by the relevant 
authorities and system operators in order to provide comfort and safety to passengers. The 
objective this research is to study some parameters that impact the comfortability of passengers 
and to obtain feedbacks from passengers for different rail transit system. Site observations were 
conducted to obtain data such as noise, vibration, speed and coach layouts which will be 
verified by using the passenger feedback outcomes. The research will be focused in and around 
the Kuala Lumpur City for the duration of 10 months. Four rail transit systems were being 
considered, i.e. Train Type A (LRA), Train Type B (LRB), Train Type C (MRL) and Train 
Type D (CTR). Data parameters obtained from field observations were conducted in the rail 
coaches during actual operation using apparatus among others the sound level meter (SLM), 
vibration analyzer (VA) and the global positioning system (GPS). Questionnaires were 
prepared as passenger feedback instrument, focusing on the level of comfortability in rail 
coaches. The outcomes of these analyses showed that CTR was the best and most comfortable 
coach, followed by LRA, LRB and MRL. Using the passenger feedbacks (MBP) it was also 
found that the ranking values for the railway transit system using Rail Coach Comfortability 
(RCC) is RCC (MBP) were the same as the outcomes using the RCC (parameters). In 
conclusion, it was found that this research has successfully determined the level of 
comfortability as determined in its aim and objectives. From this research, it is hoped that the 
relevant authorities will continue to find ways to enhance the comfortability and safety of its 
train coaches especially its passengers and the community at large.
Service Quality of Malaysian Public Transports: A Case Study in Malaysia
This research is about the Service Quality dimension became the major determinant to influence the Service Quality of public transports in Lembah Bujang area, Kedah Darul Aman, Malaysia. This study has been done in Lembah Bujang area, Kedah. The objective of this research is to investigate the relationship between independent variables which is tangible, reliability and responsiveness dimension that influences the Service Quality of the public transports which is buses and taxis in Lembah Bujang area and which Service Quality dimension are mostly influences the Service Quality. The population of this research is about 300 populations in the Lembah Bujang housing area phase one area which is frequent public transports user. In this study, convenience sampling was used which is only 169 respondents were selected. The researcher use Descriptive Statistic, Pearson Correlation, Multiple Regressions and Cronbach’s Alpha in order to analyze the data gathered by using Statistical Package for Social Sciences (SPSS) version 15.0. The result indicates there are positive correlations between Service Quality and tangible, reliability and responsiveness of Service Quality dimensions. The most Service Quality dimensions influence the Service Quality is tangible dimension which is focuses on Cleanliness/Comfortable of physical facilities. For the future research it can determine the others important factors that influences the service quality of the public transports also needs to focus on others service quality dimension which is empathy and assurance in SERVQUAL model of Service Quality.

Cette etude a ete realisee dans la region Lembah Bujang, Kedah.L'objectif de cette recherche est d'etudier la relation entre les variables independantes qui sont les dimension de la tangibilite, de la fiabilite et de la reactivite qui influencent la qualite de services de transports publics, c'est-a-dire les autobus et les taxis dans la region Lembah Bujang et la dimension de qualite de service qui influe le plus sur la qualite de service. Les sujets de cette recherche sont d'environ 300 personnes dans les quartiers d'habitation de Lembah Bujang, qui sont des utilisateurs frequents de transports en commun. Dans cette etude, l'echantillon de convenance a ete utilise et seulement 169 repondants ont ete selectionnes.Les chercheurs ont utilise la statistique descriptive, la correlation de Pearson, les regressions multiples et l'Alpha de Cronbach afin d'analyser les donnees recueillies a l'aide du paquet statistique pour les sciences sociales (SPSS) version 15.0. Le resultat indique qu'il y a une correlation positive entre la qualite de service et la tangibilite, la fiabilite et la reactivite des dimensions de la qualite de service. La dimension de qualite de service qui influence le plus la qualite de service est la dimension tangible qui met l'accent sur la proprete / le confort des installations physiques. Pour les futures recherches, on peut determiner d'autres facteurs importants qui influent sur la qualite de service des transports publics, pourtant on doit egalement se concentrer sur d'autres dimensions de qualite de service qui est l'empathie et l'assurance dans le modele SERVQUAL de la qualite de service.Mots-Cles: qualite de service; tangible; fiabilite; reactivite; transports publics
New approach to vision-based BGA package inspection
Ball grid array (BGA) techniques have developed very fast due to the advantages of more I/O ports, small size, and so on. In this paper, a vision-based algorithm for BGA package inspection is proposed to accurately estimate center and diameters of solder-balls of BGA packages, so that defects of BGA packages, such as missing or extra balls, oversize or undersize balls, over-height or under-height balls, and pitch can be detected for ensuring the quality of BGA packages.
