Automatic fruits identification system using hybrid technique
In this work, a combination of artificial neural network (ANN), Fourier descriptors (FD) and spatial domain
analysis (SDA) has been proposed for the development of an automatic fruits identification and sorting system. Fruits images are captured using digital camera inclined at different angles to the horizontal. Segmentation is used for the classification of the preprocessed images into two non-overlapping clusters from which shape boundary and signatures are estimated using FD and SDA technique. Furthermore, color information obtained from the extracted red-green-blue color components of the fruits images during ANN training process is used in accurately detecting the color of such a fruit. The two independent paths are then combined for fruits sorting and identification purposes. The performance of the developed hybrid system has been evaluated at three different angles of camera inclination
from which an accuracy of 99.1% was obtained

Sub-chronic toxicological evaluation of the Baccaurea angulata (Belimbing Dayak) fruit juice in rats
Summary. Toxicity study on normal rats was carried out using freeze-dried whole fruit (FDWF) sample of Baccaurea angulata. Animals in these sub-chronic studies illustrated no significant changes in general behaviour, growth, and relative organ weights. In liver function test, total protein and alkaline phosphatase significantly decreased in male treated Group-II (300 mg/kg), giving 36.50±2.65 g/L and 47.90±4.48 U/L, respectively. Meanwhile, low dose female group (Group-II), there was significant increase in the same parameters, giving 63.70±5.28 g/L and 73.50±12.91 U/L respectively. In general, there was no evidence that demonstrated any tissue injury, the no-observable adverse effect level for B. angulata was 1,200 mg/kg administered orally for 13 weeks.
Industrial relevance. The whole fruit juice of B. angulata, one of underutilized fruits found in Borneo island of Malaysia, has the potential to be utilized for preparation of health drink. Our earlier studies on the fruit showed that it contains the essential nutrients including dietary fiber that are good in promoting human health. Besides that, it has also been found to contain essential amount of antioxidant constituents as confirmed by antioxidant activities. This present study, additionally, found it to be safe and thus offer diverse potentials to be developed for nutraceeutical and functional fruit product
Design and performance of 20 watts portable solar generator
A new portable solar generator has been developed to generate electricity. It has the potential to replace petrol generator, widely used by peddlers at night markets (pasar malam). Conventional generators are heavy, oily, have high maintenance and use fossil fuel to generate electricity. The solar generator can generate 20 Watts of electricity. This amount of power can supply up to 96 hours of electricity for the purpose of lighting and running small electrical appliances. The power output is (alternating current) AC current using 150 Watts inverter with 200 Watts surge, suitable for all commercial single phase electric appliances. Solar charge controller is used to maximize the charging rate and to protect the battery. The system has low maintenance whereby the batteries need to be changed every three to four years, depending on the usage. The main concepts of portable solar generator are to reduce installation cost and to introduce a compact design of an optimal energy sizing system. The materials used to develop the solar generator can be easily obtained from local markets, thus reducing the cost of developing the system and making it suitable for commercialization
