Tree structured modeling is a data mining technique used to recursively partition a data set into relatively homogeneous subgroups in order to make more accurate predictions on the future instances. Decision tree algorithms have the ability to deal with missing values or wrong data. While this ability is considered to be advantage, the extreme effo

Background: It has long been debated among audiologists whether pure tone and warble tone can be used interchangeably in clinical settings to quantify the amount of hearing threshold. The disputes on this issue inspired this study to investigate the differences in hearing threshold between pure tone and warble tone in audiometry testing. Materials

A wall climbing robot is a robot with the capability of climbing vertical surfaces. This paper describes the design and fabrication of a quadruped climbing robot. We are required to design and create a wall climbing robot which uses suction as a means of sticking to the wall. The robot will be controlled using Basic Stamp and the movement of its le

Adult mesenchymal stem cells are candidate cells for cartilage tissue engineering due to their ability to undergo chondrogenic differentiation after extensive expansion, and induced with growth factors.1 Sustained delivery of transforming growth factor beta (TGF-ß)3 induces differentiation of human bone marrow-derived stem cells (BMSCs) into chond

Senna alata or Cassia alata (C. Alata) is a plant belonging to the family Leguminosae and it has antifungal and antimicrobial activities.This research aims to extract Cassia alata using known extraction procedure, followed by microencapsulation using biodegradable Poly (lactide-co-glycolide) (PLGA). The microencapsulation is envisaged to release th

Senna Alata or Cassia Alata (C. Alata) is a plant belonging to the family Leguminosae and has been documented to have antifungal and antimicrobial activities. The purpose of this study was to design poly-(lactide-co-glycolide) (PLGA) microspheres for a controlled delivery of the C. Alata extract, over 2–4 weeks. The microspheres were produced by

Writing a research article in order to publish it in a high-impact journal is a crucial part of making sure your research is worthy and has an impact outside your organization. There are, however, systematic steps for writing a quality scientific research manuscript that can lead to successful publication without rejection. It’s not difficult to

Conventional grinding of silicon substrates results in poor surface quality unless they are machined in ductile mode on expensive ultra-precision machine tools. However, precision grinding can be used to generate massive ductile surfaces on silicon so that the polishing time can be reduced immensely and surface quality improved. However, precision

Silicon substrates are difficult to grind to good surface finishes using conventional machining. Ductile mode machining is often required to have flawless machining but this requires the use of expensive machine tools. However, precision grinding using conventional machine tools could generate large amounts of ductile streaks on ground silicon surf

This study reports the use of Taguchi and Box-Behnken designs for minimising surface roughness in precision grinding of silicon using resin-bonded diamond mounted wheels. Taguchi method was used to study the effect and optimisation of grinding parameters while Box-Behnken method was utilised to develop a mathematical model relating the average surf
