Problem statement: In the past decade, resident satisfaction has been used as an important
indicator in evaluating student housing quality and services. This study investigates the level of
resident satisfaction with student housing facilities. In particular, it examines the level of student
satisfaction with living accommodations at one of the leading universities in Malaysia. Approach: The
residential satisfaction framework was based on post-occupancy evaluations and has been utilized in
previous studies; we expand the framework to address physical and social variables. Face-to-face
surveys were conducted with participants who were selected using a cluster sampling technique.
Results: The results show a mean satisfaction level of 2.61, which indicates that students are generally
satisfied with student housing facilities. This score was lower, however, than the results of previous
studies. Conclusion: By assessing residential satisfaction among students, we hope to provide valuable
feedback to housing administrators and facility managers of higher learning institutions, thus enabling
them to improve their services and offer better housing facilities in the near future.

Detection of non-structural protein 1 (NS1) of dengue virus can gives early diagnosis of dengue and shows high sensitivity. Current technique uses for the dengue NS1 detection is enzyme-linked-immusorbent assay (ELISA) on 96 microwell plate. However, the assay requires long incubation time about 90 minutes (for antigen–antibody interaction) and total assay time takes almost 2 hours and 30 minutes to complete. Therefore, a lab-on-a-disk with applied centrifugal force is proposed as a potential microfluidic platform to reduce the assay time by effectively mix and separate liquid in the ELISA assay. The advantages of the technique are having large specific volume, short diffusion length, minimum reagents consumption and simplify procedures. The lab-on-a-disk will exploit centrifugal and capillary forces to act as a passive valve to control the flow sequence of different solutions involved. Each steps of the ELISA process is carried out automatically by controlling the rotation speed of the disk. This paper will describe the lab-on-a-disk platform on its microfluidic principles, fabrication process, detection systems, biosensor applications, and the proposed model for
dengue NS1-ELISA assay.

This paper presents the design and simulation of a DC-DC boost converter which uses wind energy as input source. Nowadays, wind is a type of renewable energy that is sustainable and clean compared to other alternative energy. Generally wind in Malaysia blows at variably low speed thus producing variably low input voltage as energy source. DCDC boost converter can be used to increase the output voltage to a level suitable for domestic use. In this project, a closedloop DC-DC boost converter circuit was designed and simulated using MATLAB SIMULINK based from a topological circuit. In the simulation, the circuit was tested with different low input voltage values to a setpoint of 240V. In order to improve the output voltage transient response, Fuzzy Logic Controller is designed and implemented at the circuit to set the duty cycle of the switching device for the boost converter. The result has indicated better performance for boost DC-DC converter with FLC controller.
