Article
Full-text available
Wind gusts at the pedestrian level around buildings are caused by both effects of turbulent flow generated by surrounding buildings and the turbulent characteristic of the approaching flow. Although numerous researchers have stochastically investigated the contribution of buildings to gusts, the probabilistic characteristics of approaching flow hav...

Background The cultural and genetic diversity of the Southeast Asian population has contributed to distinct cardiovascular disease risks, incidence, and prognosis compared to the Western population, thereby raising concerns about the accuracy of predicted risks of existing prognostic models. Objectives We aimed to evaluate the predictive performan...
Article
The power train efficiency of fuel cell vehicles (FCV) can be enhanced by improving the hydrogen energy utilization. Based on a mini FCV running on a 2 kW open-cathode Polymer Electrolyte Membrane (PEM) fuel cell, a waste heat recovery system design needs to be developed as an approach towards higher energy efficiency. The novelty of the system is...

Fiducial points of photoplethysmogram (PPG), first derivative PPG (VPG), and second derivative PPG (APG) are essential in extracting numerous parameters to diagnose cardiovascular disease. However, the fiducial points were usually detected using complex mathematical algorithms. Inflection points from derivatives waveforms are not thoroughly studied...

A Mobile Offshore Production Unit (MOPU) is any type of portable structure that can be reused when procuring oil and gas from the seabed. There are few reasons why MOPU is chosen over the conventional fixed offshore platforms, mainly due to its ability to be installed and relocated in a short period, low installation, and abandonment cost, and prov...
Article
Many studies have been conducted to assess the effects of indoor air quality (IAQ) on human health. However, there is still a lack of studies available about the adverse health effects on children’s respiratory health at Child Care Centers (CCC). The aim of this paper was to investigate the risk factors for respiratory symptoms and identify the roo...
Article
Full-text available
The use of Computational Fluid Dynamics (CFD) as a research tool has been utilized in many ways to predict the turbulent flow nature and pollution dispersion in an urban environment such as street canyon. Apart from the advance advantages offered by this method, some problems can be arising on respect to accurate prediction of data and uncertaintie...
Article
Full-text available
Buildings in urban area consist of various heights and building arrangements. Meanwhile, the pedestrians at the area must be considered for their wind comfort and wind safety. This is because, near high-rise buildings, high wind velocities are often introduced at pedestrian level that can be experienced as uncomfortable or even dangerous. Nowadays...
Article
Full-text available
The pedestrian level is an important area where most of the human activities occur in this area such as walking, reading, and cycling. Along with the pedestrian activities, there are small street shops are builds and presences of the vehicle at the street canyon where people park their cars in this area. This study aims to investigate the effect of...
Article
The aim of this paper is to report the findings of indoor air quality study at childcare centers in Malaysia. Modified American Thoracic Society and the Division of Lung Diseases (ATS-DLD-78) questionnaire was used to gather information from parents regarding their children’s respiratory symptoms. IAQ parameters were measured for air temperature, h...
Article
Full-text available
The use of CFD as a research tool has been adopted successfully in many ways to predict the turbulent flow nature and pollutant dispersion properties in urban environment. Apart from the advance advantages offer by this method, some problems can be arising on respect to accurate prediction of data and uncertainties of assumption that are made in nu...
Article
Full-text available
This present study focused on the performance of net flow rate inside closed loop mechanical circulatory system with single and double pinching impedance pumps which generates a unidirectional flow of fluid around closed loop of soft viscoelastic tubing. The experimental setup consisted of viscoelastic tubing connected between two ends of rigid tub...
Article
Full-text available
This paper reports the results of flow field analysis within and above a two-dimensional street canyon with various overhang lengths using large-eddy simulation (LES). Simulations were conducted for a constant canyon aspect ratio of W/H = 3, where W is the street width and H is the building height. Three different overhang lengths were simulated wi...

This study investigates the characteristic of spatially averaged mean velocity profile and the flow pattern within urban canopy layer especially in pedestrian level using CFD technique. Large eddies simulation (LES) was used to perform a series of simulation of the flow around block arrays with staggered arrangement under various conditions of aspe...

A formula-type car design with fendered rear tyres is chosen as the ARTeC's design for 2011 Perodua Eco-Challenge. This paper aims at investigating aerodynamics of ARTeC's EMo-C car, measuring drag coefficient in particular and observing airflow around the body. There are two means of measuring the drag, the first is by simulating the air flow via...
Article
Thin-walled metallic tubular structures are generally used as impact energy absorber in automotive structures due to their ease of fabrication and installation, high energy absorption capacity and long stroke. However, unlike a normal passenger car where the impact energy can be distributed throughout the whole structure, the impact energy absorbin...
