Fractal coding of digital images ooers many promising qualities. However the coding process suuers from the long search time of the domain block pool. In this paper, we obtain mathematical results on the distance measure used in the search. Then we derive an incremental procedure to bound the domain block pixels. We arrange the domain blocks in a tree structure, and utilise the procedure to dir...

Tah The use of natural fibres in polymer composite applications has gained great attention over the last decade, due to weight, economic and en...
Increased durability of permanent TiAl6V4 implants still remains a requirement for the patient's well-being. One way to achieve a better bone-material connection is to enable bone "ingrowth" into the implant. Therefore, a new porous TiAl6V4 material was produced via metal injection moulding (MIM). Specimens with four different porosities were produced using gas-atomised spherical TiAl6V4 with d...
The purpose of this study is to identify and describe the perceptions of experts on the characteristics of beltline moulding quality success factor. This study was done through questionnaire and interview with 14 experts in the roll forming process. From this study we found; first, the experts placed attributes such as salary satisfaction, training and skill requirement and workplace environmen...
Abstract—The plastic industry plays very important role in the economy of any country. It is generally among the leading share of the economy of the country. Since metals and their alloys are very rarely available on the earth. Therefore, to produce plastic products and components, which finds application in many industrial as well as household consumer products is beneficial. Since 50% plastic...
This research work aims to experimentally evaluate the influence of resin modification using Titanium dioxide (TiO2) nanoparticles on mechanical properties viz. flexural, tensile and Inter Laminar Shear Strength (ILSS) basalt reinforced epoxy composites based ASTM standards. The laminates were fabricated a combination hand lay-up compression moulding techniques. Five different weight proportion...
A composite hip prosthesis (CHP) made from alumina reinforced ultra high molecular weight polyethylene (UHMWPE) was designed and manufactured. The main objective of the study was to fabricate the composite hip prosthesis which would be an ideal replacement of metallic one as bone is a composite material consisting of collagen fibre matrix and embedded hydroxyapatite mineral. With this idea we d...
Abstract The production of injection moulded components with low shrinkage and warpage is a constant challenge for manufacturers. thermal design the mould plays an important role achievable quality, especially placement cooling channels. This usually based on empirical knowledge designers. construction supported iteratively by moulding simulations. In case thick-walled plastic optics big wall t...
