A Technique for Improving Web Mining using Enhanced Genetic Algorithm

World Wide Web is growing at a very fast pace and makes a lot of information available to the public. Search engines used conventional methods to retrieve information on the Web; however, the search results of these engines are still able to be refined and their accuracy is not high enough. One of the methods for web mining is evolutionary algorithms which search according to the user interests...

Preparation of Structured Polymer Composites Using an Ultrasonic Focusing Technique

This research uses ultrasonic standing waves to arrange sub-micron size particles within polymeric materials in layered or stratified configurations. Such composites have the potential to exhibit unique mechanical and transport properties. Through the combination of ultrasonics, polymer science, and particle science, it is hoped that a range of advanced thinfilm materials can be developed as ba...

Polymer Composites for Bone Reconstruction

The need for reconstructive surgery of bones is continuously increasing along with the ageing of the population as well as the increase of traumatologic injuries. In the United States, the number of bone grafts was 350,000 in 2001. Nowadays, over 500,000 bone graft procedures are performed annually, and approximately 2.2 million worldwide (Giannoudis et al., 2005). The estimated cost of these p...

Microencapsulation of Citrus grandis peel oil using interfacial precipitation chemistry technique for repellent application

Essential oil of Citrus family plant is known to have repellent effect against mosquito. Unfortunately, due to its high volatility effect, its repellency effect was compromised. The incorporation of essential oil in a microencapsulation formulation has been shown to help improve the stability and potency of the repellent. In this study, Citrus grandis peel oil (CGPO) was encapsulated by using t...
