Time-frequency analysis based methods for classification of newborn cry signals
The infant cry classification implies non invasive objective methods, classification of different patterns of infant cry utterances and adoption of artificial and digital signal processing techniques. It has been commenced ... -
Black-box modeling and adaptive control of hybrid thermoelectric refrigerator systems
Vaccines carrier has been used to keep the temperature within 2–8°C. However, a poorly functioning vaccines carrier may expose the vaccines to freezing temperatures. Hybrid Thermoelectric Refrigerator (H-TER) systems are ... -
Bio-inspired sensor data fusion for herbal tea flavour assessment
Herbal-based products are becoming a widespread production trend among manufacturers for the domestic and international markets. As the production increases to meet the market demand, it is very crucial for the manufacturer ... -
An improved mobile robot based gas source localization with temperature and humidity compensation via slam and gas distribution mapping
This research is concerned with the problem of localizing gas source in indoor environment using a mobile robot. The problem could be seen as similar to the event of hazardous gas leak in a building. Since the environment ... -
Investigation of nonlinear feature extraction techniques for facial emotion recognition
Over the last decades, facial emotion recognition has received a significant interest among researchers in areas of computer vision, pattern recognition and its related field. The increasing applications of facial emotion ... -
Implementation of feature selection and weighting methods for emotion recognition from human actions
Emotion is a natural, instinctive state of mind emanating from one's circumstances, mood or relationships with others. Emotion can be characterized primarily by the psycho-physiological expressions, biological reactions, ... -
Design and development of a thought controlled intelligent robot chair with communication aid
The fundamental movements like walking and speech communications are the basic needs of human beings in their daily life. Differentially Enabled (DE) communities have functional limitations that vary from primary/complicated ... -
A visual tracking range of motion assessment system for lower limb joint
Accurate range of motion (ROM) measurement of lower limb joint motion is important for assessing the severity of human lower limb injuries. It is essential for assisting the medical doctor and physiotherapist to determine ... -
Burst strength and impact performance on glass fibre reinforced epoxy (GRE) composite pipes
While in service environment, the changes in the degradation mechanisms of the GRE composite pipes may occur in the matrix, fibre, and the fibre-matrix interfacial regions due to water diffusion. These composite pipes may ... -
Image enhancement and feature extraction techniques for intelligent thalassemia screening procedures
Thalassemia is an inherited blood disease that effects the production of red blood cells (RBC) in the body. The deficiency of RBC that constitutes 99% of blood cells will affect their main function as oxygen carrier. The ... -
Automated marker placement based real-time facial emotional expression recognition system
Facial expression recognition attracted several researchers over the past several decades and most of the researchers in the literature focus on facial expression recognition in “offline” and very few research works ... -
A study on atmospheric pressure plasma jet for hospital acquired bacterial inactivation by different working gases with varying flow rate and exposure time
Atmospheric Pressure Plasma Jet (APPJ) is ionized gas that is generated at atmospheric pressure and at room temperature, by allowing the gas to flow in a small tube with the higher voltage supplied to the area. Plasma ... -
Development of pure and adulterated honey measurement system using multiple frequencies six-port reflectometer (SPR)
This thesis presents a study on the development of multiple frequencies Six-Port Reflectometer (SPR) in characterizing pure and adulterated honey through reflection measurement. As honey adulteration is one of major health ... -
Surface hardness effects on biomechanics foot response during running
Running activities can be either beneficial or caused chronic injuries among runners. Surface hardness and shod condition can be considered as the major factors that influenced the running performance. Understanding the ... -
An integrated indoor air quality monitoring system with pollutants recognition and enhanced indoor air quality index
Poor indoor air quality (IAQ) may pose threats to human’s health. The concentration level of harmful gases and contaminants in polluted indoor air is up to five times higher than in normal indoor air. In order to ensure ... -
Odour source localization strategy for multiple robots using swarm intelligence with odour-gated anemotaxis
Animals such as silkworm moths, dogs and blue crabs have exhibited odour localization capabilities in nature. This amazing ability is exhibited in complex airflow conditions which produces highly dynamic and unpredictable ... -
Harumanis mango quality assessments technique based on high level features fusion of infra-red thermal and optical image
Mangoes imported from other parts of the world, especially Malaysia, Thailand, Mexico and the Philippines, are usually available all year round but in Perlis, Malaysia there is one unique and famous mango is Harumanis mango ... -
Preliminary analysis using dielectric properties to characterize nHA/starch based scaffolds
In this study, the possibility of dielectric properties as an alternative method to characterize the physical properties of nHA/starch based scaffolds has been conducted. The relationship between dielectric properties and ... -
Development and characterisation of hybrid napier/glass fibre reinforced epoxy composites
Owing to serious environmental concerns in recent years, researchers have been driven to investigate the use of sustainable materials as a substitute for common polymer composites manufactured with synthetic fibres, such ... -
