- PublicationModelling The Transmission Of Tuberculosis In Closed Space Using Microscopic Pedestrian Simulation(2023-02)Sabri, Nor ShamiraDue to the infamous COVID-19 pandemic, Tuberculosis deaths are rising for the first time in more than a decade. Tuberculosis is the second (after COVID-19) deadliest infectious killer that has been exists in this world for centuries. Despite the availability of adequate vaccination, it is still roamed around the world and became one of the leading diseases that contribute significantly to the world’s mortality rate. Therefore, this works aims to simulate how this infectious disease spread by utilizing the Susceptible-Infected (SI) model. As the research progresses, it is found that the general epidemiological studies that uses compartmental method ignore the heterogeneous of social interaction between humans. Thus, this research has proposed the integration of the Social Force model with the SI approach to imitate realistic human interaction while capturing the pathogen transmission process from one person to another. This work aims to simulate the movement and interaction between infected person and another susceptible person in a closed space when an infectious disease is present and develop with a process-oriented methodology framework following this setting set in the research. The methodological framework proposed is divided into three major stages: problem characterization, model construction also model analysis and evaluation, which work as step-by-step processes to achieve the objective sets.
- PublicationPredictors Of Flourishing Among Elderly In Penang, Malaysia: The Role Of Demographic Variables And Perma Elements(2022-07)Liew, Wei PengFlourishing is a state of optimal mental well-being. It is the experience of doing and living well in all aspects of one's life, including psychological and social well-being. Flourishing plays a significant role in all life span, and every person has the potential to flourish. Elderly as the growing age group in Malaysia can benefit from being flourished. Nevertheless, current approach to studying flourishing is too general and limited studies have focused on flourishing, particularly among Malaysian elderly from a heterogeneous society with diverse cultural backgrounds. Each ethnicity has its own definition of what it means to flourish. By understanding the definitions of each ethnicity, interventions, programs, or measurements of those who flourish and those who do not can be taken appropriately. As a result, this study focuses on the role of demographic variables (e.g., age, gender, ethnicity, religion, marital status, source of income and education attainment) and elements in PERMA (e.g., engagement, positive relations with others, meaning in life and accomplishment) in contributing to flourishing among Malaysian elderly from various races.
- PublicationA Simulated Annealing-Based Hyper-Heuristic For The Flexible Job Shop Scheduling Problem(2023-03)Kelvin, Lim Ching WeiFlexible job shop scheduling problem (FJSP) is a common optimisation problem in the industry. The use of parallel machines allows an operation to be executed on a machine assigned from a set of alternative machines, raising a combination of machine assignment and job sequencing sub-problems. A straightforward technique to solve the FJSP is to apply a pair of machine assignment rule (MAR) and job sequencing rule (JSR), i.e. a MAR-JSR pair. However, the performance of each MAR-JSR pair is problem-dependent. In addition, within an algorithm execution, the MAR-JSR pair performs differently at different problem states. Given a wide range of MAR-JSR permutations, selecting a suitable MAR-JSR pair for a FJSP becomes a challenge. Positive outcomes on the application of simulated annealing-based hyper-heuristic (SA-HH) in addressing similar scheduling problem has been reported in the literature. Hence, this research proposes the SA-HH to produce a heuristic scheme (HS) made up of MAR-JSR pairs to solve the FJSP. The proposed SA-HH also incorporates a set of problem state features to facilitate the application of MAR-JSR pairs in the HS according to the state of the FJSP. This research investigates two variants of SA-HH, i.e. SA-HH based on the HS with problem state features (SA-HHPSF) and without problem state features (SA-HHNO-PSF).
- PublicationIdentifying Criteria For The Implementation Of Augmented Reality In Malaysian Tourism Industry(2022-12)Ahmed, Abdul Salam WaqarTourism sector is one of the most important sectors for the Malaysian. To advance the tourism sector, the Fourth Industrial Revolution technologies should be utilised. This has been proven viable by many researchers globally. However, there is currently a lack of information on the utilisation of the Fourth Industrial Revolution technologies in the Malaysian tourism industry. Crimes such as pickpocket is also a common occurrence in Kuala Lumpur hence a way of alerting the tourists of crime hotspots is important, as such events could negatively impact their experience visiting Malaysia. The three main issues that would be focused in this research is improving the walking navigation of tourists visiting Kuala Lumpur, to improve overall tourist safety and improving the current marketing methods of DBKL (Kuala Lumpur City Hall). This research aims to study the feasibility of integrating the Fourth Industrial Revolution technologies into the Malaysian tourism industry to solve the issues mentioned.
- PublicationHybrid Of Optimized Random Forest And Extreme Gradient Boosting For Online Learning Style Classification(2019-03)Haziqah ShamsudinEducational Data Mining (EDM) have raised a lot of attention among researchers since the last few decades. EDM is used to gain more insight into the behavior of learners by building models based on data collected from learning tools which result in improving learning system to be more personalized and adaptive. Learning style of specific users in the online learning system is determined based on their interaction and behaviour towards the system. Felder-Silverman’s learning style model is the most common online learning theory used in determining the learning style. Initially, in determining the users’ learning styles, users are asked to fill in the questionnaires which is designed to learn their learning style at the end of the learning sessions. However, this method is time consuming and the result are not reliable due to the human factors behavior. Thus, the researchers started to study the learning style by using an automated approach in which the activity log files are collected in order to understand the interactivity behaviour of the users with the system.
