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 ... -
Photovoltaic powered uninterrupted power supply based on PIC microcontroller
This thesis presents the photovoltaic (PV) powered uninterrupted power supply (UPS) system based on PIC microcontroller. The study of solar radiation is very important to know its potential to develop the PV powered UPS ... -
Design and implementation of embedded tracking system using spatial parallelism on FPGA for robotics
The robot tracking system is one type of utilization system on a mobile robot and generally utilized as a part of numerous perspectives, for example, security or military. In this project, an active and passive robot ... -
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 ... -
A new three-dimensional code for OCDMA system
Many codes have been proposed for incoherent OCDMA based on one-dimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) by exploiting one or more resources simultaneously. The 3-D Perfect Difference (3-D PD) ... -
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 ... -
Study on leave image processing with application in herbal classification and early detection of chili plant disease
Herbs have been widely used in food preparation, medicine and cosmetic industry. Knowing which herbs to be used would be very important in these applications. The current way of identification and determination of the ... -
Hardware implementation of RGB to HSL converter using FPGA
The RGB (Red, Green, Blue) colour model is the basic colour model and add together to produce full colour range. RGB is unable to produce sufficient information for digital image analysis. The HSL (Hue, Saturation, and ... -
Circularly polarized mimo array antenna for 5.8 Ghz point-to-point communication
Three different design of circularly polarized multiple input multiple output (CPMIMO) antenna for point-to-point communication is proposed in this thesis. All design involves with combination of three type of technique ... -
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 ... -
LMMSE-based low complexity image denoising in non-uniform directional filter bank
This dissertation is about creating a non-redundant, effective and low-complexity denoising method. Denoising an image involves removing noise from an image to keep the original elements of the image and remove unwanted ... -
