Respiratory system modelling can assist clinicians in making clinical decisions during mechanical ventilation (MV) management in intensive care. However, there are some cases where the MV patients produce asynchronous breathing (asynchrony events) due to the spontaneous breathing (SB) effort even though they are fully sedated. Currently, most of th...

Edge detection plays an important role in computer vision to extract object boundary. Multiscale edge detection method provides a variety of image features by different resolution at multiscale of edges. The method extracts coarse and fine structure edges simultaneously in an image. Due to this, the multiscale method enables more reliable edges are...

Traffic congestion has become a serious issue due to the growing number of vehicles in Malaysia. Traffic light control system is widely used to control the flow of road junction. Currently, most of the traffic light system used pre-time and count down timers to control traffic flow. Due to the fixed-time setting, often the system unable to handle u...

In aquaculture industry, measurement of fish length plays an important role in monitoring and determining fish growth, gender, age and reproduction. Currently, fish rearing industries are using measuring wooden board or acrylic plastic with the scale attached to the board itself. However, this method is causing a stress on the fish when measuring t...

Short T1 Inversion Recovery (STIR) is a fat suppressed technique commonly used in Magnetic Resonance Imaging (MRI) to suppress fat signals from tissues. The technique is to improve visual inspection during diagnosis. Suspected fluids will appear bright in STIR to identify the abnormality. Due to hardware limitation, tissue contrast and signal-to-no...

Short Inversion Time Inversion Recovery (STIR) is one of the fat suppression imaging techniques which involves inversion recovery pulse sequences. STIR uses time delay TI to nullify longitudinal magnetisation. This is to suppress the fat signals from tissues and increase the echo time (TE) so that another sequence called T2 will increase the contra...
Conference Paper
The purpose of this paper is to study a mathematical formulation of a water level control loop in a process control training system. Mathematical modeling was carried out to understand the dynamics of the water level changes in the water tank for different settings of the PID controller mode. The idea of transfer function was used to represent the...
Conference Paper
This paper is to focus on to design of the basic geometry of helical antenna in small size at frequency 2.46 GHz. Several parameters dimensions and helical profiles were studied in order to obtain a suitable frequency range. The software that was applied for this simulation is the CST Microwave Studio (CST MWS) which is analytical tool that provide...

This paper presents the performances of Proportional (P), proportional-integral (PI) and proportional- integral-derivative (PID) modes controller to control an automatic water level control system. This project is developed to verify the performance of water level control system using PID control modes. The measurements of water level control syste...
Conference Paper
The purpose of this paper is to study a mathematical formulation of a water level and product liquid temperature control loop in a boiler drum and heat exchanger process control training system. Mathematical modeling was carried out to understand the dynamics of the liquid product temperature for different settings of PID controller mode. The model...
Conference Paper
This paper explores the possibility of fast and automatic hole detection using improved half wave power spectral detection. A radio that can sense and understand its local radio spectrum environment, to identify temporarily vacant spectrum and use it, has the potential to provide higher bandwidth services, increase spectrum efficiency and minimize...
