The Agent-based Rough Set Data Mining Tool

The novelty of ROUGHAGENT compared to previous agent-based rough set technique, is that it is employed within default rules generation framework (DRGF). It improves the existing Emergent-based Approach where the running time has been reduced thus maintaining the number of rules and classification accuracy. ROUGHAGENT controls the number iteration to avoid the unnecessary mining path but reserves the generation of simpler and shorter rules. ROUGHAGENT improves the mining speed and maintains the quality of knowledge.

Synthetic Wood Composition & Method of Processing Thereof


The invention relates to the technology and materials for processing thermoplastic natural rubber wood from a blend of natural rubber and polyethylene, as the matrix and cellulosic fibers, rice husk or any dried parts of the rice plant/grass and wood powder, as the filler.
The composite will be further improved in properties (hardened and strengthened) with addition of particulate filler such as clay, and chemical modifications to the matrix. The special properties of the thermoplastic composite wood like mouldability and resistance to moisture and fungi enable it to be applied in the construction of formed products for outdoor applications (garden furniture) and in wet indoor areas (tiling applications). It can be applied to door fittings and furniture through the addition of pigments or painting of the composite for a better finishing. The use of agro-waste such as rice husk and wood flour helps to lessen environmental problem related to rice and wood industries.

Superior Red Rice with Low Gi

Five transgressive variants derived from a cross between the wild rice, Oryza rufipogon Griff and a high yielding Malaysian rice cultivar O. sativa L. indica cv. MR219 were evaluated for red pericarp stability, grain yield potential and resistance to blast disease. The experiment was conducted at a single location over two seasons. Grain yield was significantly higher (15%) than MR219 for variant G33 (R14-3-66-4-B-B) which also possessed the desired physico-chemical properties of grain with high antioxidant activity (Ferric Reducing Ability of Plasma = 107.72 molFeSO4/g and Total Phenolic Content = 0.49 mg GAE/g), low glycemic index (GI =51) and low insulin index (II = 39). The same variant was resistant to blast disease and the red pericarp colour was stable. The transgressive variant G33 is recommended for cultivar development as a specialty rice.

Randomly Textured Nanoscale Surfaces for Low-Cost Manufacturing of Si Solar Cell

Industrial Si solar cell manufacturing is based on wet-chemical texturing to remove saw-damge, reduce reflection, and plasma enhanced chemical vapour deposition to deposit high index SiN films to reduce reflection as well achieve adequate surface passivation. Wet-chemical texturing requires large quantities of water and chemicals, SiN deposition requires expensive plasma processing equipment as well as highly flammable and reactive silane gas. Both these factors contribute to higher manufacturing costs and environmental pollution. Our work seeks to reduce manufacturing costs through an environmental-friendly approach.

Process For Manufacturing Thermoplastic natural Rubber (TPNR) Using Liquid Natural Rubber (LNR) as a Compatabiliser

Thermoplastic natural rubber (TPNR) is an elastomeric thermoplastic consisting of a blend of natural rubber (NR) and a thermoplastic such as polypropylene (PP). Normally the material is prepared by melt-mixing the components at about the melting point of the thermoplastic. TPNR is a tough material exhibiting both thermoplastic and rubber properties. The potential applications of the material are very wide. Weight seems to be a major concern in most of the applications.
Making the material lighter would be most appropriate and timely. One way of reducing the material density without loosing significantly other physical properties is by expanding or foaming the material i.e. introduction of cells or pores in TPNR. The nature of the cell formed, its size and distribution, depend on the technique of foaming and type of matrix.
Researchers at UKM have identified a method of preparing TPNR and introducing pores into the structure. The technique can be utilized to prepare the required cellular TPNR with specific hardiness, elasticity, density, modulus and other physical parameters.

Process for Manufacturing Liquid Natural Rubber (LNR)

The present invention relates to the process for manufacturing liquid natural rubber. A sufficient quantity of dried natural rubber is soaked in an organic solvent and then mixed with a sufficient amount of a photosensitizing agent solution. Alternatively, these two steps can be done in reverse order. The resultant mixture is then exposed in visible light for a predetermined time period. The molecular weight of the degraded rubber thus produces ranges from 20,000 to 100,000.

Process for Making Catalyst by Impregnation of Platinum on Activated Carbon

An impregnation process for the preparation of platinum on activated carbon catalyst (Pt/AC) using indigenous activated carbon is elucidated. Pt uptake is a very important parameter in the impregnation process to load Pt on AC. These involve three types of Pt uptakes observed when using solution of PtCl6 (pow 2-) anions , namely, -fast and strong adsorption of Pt anions on protonated sites (OHpow +), - weak adsorption on pre-adsorbed ammonium sites at medium, pH and - deposition of neutral Pt compound formed by the precipitation of Pt precursors, such as (NH)PtCl6 at high pH and HPtCl6 at low pH. A method of impregnating platinum on activated carbon comprises bringing into contact an activated carbon sample with a dissolved platinum solution, adding a base into the platinum solution to raise the pH to a range of 9.7 to 9.9, boiling the platinum solution with distilled water and evaporating a mixture of the base and the distilled water from the platinum solution by heating it to a calcining temperature.

Phonelic Resin from oil Palm Soda lignin

In the process of screening various herbs for anti-obesity activity we have investigates the effects of Jin Batu (Strobilanthes Crispus) herbal formulation in assisting weight loss of diet-induced obese rats. Lean Sprague-Dawley rats (350-450g) were fed a high-fat diet containing 31.1% fat for 14 weeks to induce obesity.
Obese rats were given S. Crispus formuation (1% w/w) in drinking water and standard rat chow diet for another 14 weeks. The assay for adipose tissues lipolysis effect was performed by measuring changes of adipose tissue weight, plasma leptin and glycerol levels and lioprotein lipase mRNA expression before and after treatment with S. Crispus supplement. The time course of body weigth, food intake, liver weight and plasma parameters (triglyceride, total cholestrol, high-density lipoprotein, low density lipoprotein) were measured. Hepatic histological examination were also performed. After 14 weeks, rats treated with S. Crispus supplement were found to have lower mean body weights, mean body weight gain and feed efficiency than control group.
They also have significantly (p<0.05) lower adipose tissue and liver weights, and leptin levels compared to control group. Mild hepatic steotosis combined with high liposys rate and LPL mRNA expressed in adipose tissue were observed in the herbal treated group. Profoundly, the positive effect of S. Crispus formulation in assisting adipose tissu weight loss was due to enhanced rate of adipose tissue lipolysis. This was confirmed through the high rate of adipose tissue lipolysis found in Obese-Herbal Traeted Group. These results demonstrated that using 1% (w/w) S. Crispus formulation as herbal supplement can assist obese rats in weight reduction and management

Parameter for a H Space Pin Photodetector

The research concentrated on a new interdigitated design based on a space-filling locus and the GUI interfaces that was created for testing it. We used a mathematical fractal in the designs in order to optimized the active area of the device and MATLAB programe to build software to test the effectiveness of the design. When put into a simulated test, the H-Space electrode produced a promising result. We compared current-time graphs of two pin photodetectors with different electrode design but with the same properties, i.e (100) silicon substrate with a resistivity of 11-16?U.cm. A concentration of 1x 1016 cm -3 phosphorus and 1x 1019 cm-3 boron were applied with the width of the active region two times wider than the width of the fingers. By running it on three different widths and applying s reverse bias voltage of 5V into the device, we obtained a graph which highlights the improvement in the rise time factor of the H space electrode devices wherein we found that the rise time factor of the H space electrode is roughly 5.1x103 A/sec while for the interdigitated electrode, the steepness is 857.8
