The effect of filler content and chemical modification on properties of polylactic acid/recycled low density polyethylene/nypa fruticans husk biocomposites
Nypa fruticans husk (NFH) filled polylactic acid (PLA)/recycled low density polyethylene (rLDPE) biocomposites had been prepared using Brabender Plasticoder EC PLUS at temperature 180˚C and rotor speed 50 rpm. The effect ... -
Effect of chemical modifications and electron beam irradiation on properties of corn cob filled chitosan biocomposite films
The chitosan (CS)/corn cob (CC) biocomposite films were prepared via solvent casting method. The effects of CC content, crosslinking agents such as glutaraldehyde (GLA), salicylaldehyde (SAL), epichlorohydrin (EP) and ... -
Boundary layer flow and heat transfer of a nanofluid over a stretching/ shrinking sheet with suction and slip effect
In this thesis, the problem of steady boundary layer flow and heat transfer over a stretching/shrinking surface with the velocity slip boundary condition and suction is considered. The fluid that considered in this study, ... -
Hybrid method of fuzzy homotopy and runge kutta fehlberg method for solving fuzzy nonlinear equations
The system of fuzzy nonlinear equations plays an important role in solving real-world problems. However, to solve the system of fuzzy nonlinear equations is not an easy task. This is patently obvious when dealing with ... -
Prediction of students academic achievement in UniMAP using data mining approach
The main objective of this research is to predict the academic achievement of the students in UniMAP who will be succeed, will be continued their study in higher level and also students whose need help in their study. ... -
A study in the theory of geometric functions of a complex variable
This thesis deals with various types of analytic geometric functions in the open unit disk, such as normalized, meromorphic, p-valent, harmonic, and fractional analytic functions. Five problems are discussed. First, the ... -
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 ... -
The evolution of microstructures and properties due to materials tool interaction during friction stir welding of similar and dissimilar al and Cu alloys
In this work, main similar (6061 aluminum alloy) and dissimilar (commercially pure aluminum and copper) materials were butt joined via friction-stir welding (FSW). The influence of FSW parameters, namely, small pin geometry, ... -
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 ... -
Measurement on strain rate sensitivity properties of rice husk/ linear low density polyethylene (LLDPE) composites under various loading rates
The dynamic compression testing and static compression testing were performed using Split Hopkinson Pressure Bar (SHPB) apparatus and a conventional Universal Testing Machine (UTM), respectively. These two techniques were ... -
Hot air solder levelling (HASL) process parameters optimization for SN100CL
Reliability of electronic packaging has now become the most critical factor in electronic industries. The prediction of solder joint failure and its shelf life becomes more challenging as the increasing demand for superior ... -
Preparation and characterization of hybrid filler reinforced UHMWPE composites for artificial joint replacement
This is a study of ultra-high molecular weight polyethylene (UHMWPE) reinforced with zinc oxide (ZnO) under various filler loadings (3, 7, 12, 18 and 25 wt.%) and hybridized with incorporation of chitosan (CS). Further ... -
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 ... -
Properties and biodegradability of low density polyethylene/ thermoplastic soya spent powder blends added spear grass powder as pro-oxidant
