Jaundice is describes as yellow discoloration of the skin and other tissues of a newborn infant and it is conjunctiva due to the bilirubin rises up to 5 mg/dL or 85 μmol/L. In Malaysia itself, about 75% of newborns had jaundiced in the first week of life, this proves by the survey made by Ministry of Health Malaysia. Traditional assessment (Kramer's Rule) is not convenient since there are limits to...
Wireless Sensor Network (WSN) is vulnerable to interference from other wireless technologies such as WLAN, Bluetooth and cordless phone due to its low transmission power, data rate and bandwidth. Energy Detection (ED) is one of the available sensing technique available in Clear Channel Assessment (CCA) that is used to reduce packet collision due to interference and hidden terminal problem. To the...
The rapid development in agro-tech plays an important role in the production of greenhouse plantations for cultivating high-value fruits, flowers and vegetables. It is imperative to constantly monitor the optimal requirement for these high value crops in every phase of the plant growth to maintain the best production quality. However, to develop a fully automated system for a plant, needs optimum...
Jaundice is defines as yellow color of the skin in newborn infant. This health condition is common in newborn and happen due to overproduced of bilirubin. Jaundice clinically appears when the level of serum bilirubin rises beyond 250μmol/L (5 mg/dl). Jaundice could cause abnormalities in the newborn such as kernicterus and cerebral palsy. The advancement of Wireless Sensor Network (WSN) technology...
The ubiquitous increase in wireless technologies utilizing the 2.4 GHz frequency band leads to spectrum congestion that reduce Quality of Service (QoS) of wireless technologies especially IEEE802.15.4 Wireless Sensor Network (WSN) due to its low data rate and low transmission power characteristics. A number of research proposed channel separation by utilizing Energy Detection (ED) as a solution to...
Volatile organic compounds (VOCs) or volatile metabolites are small molecules and comprise a chemically diverse group of organic compounds, with a low molecular weight in the range of approximately 500 Daltons. They have low boiling points and high vapor pressure under ambient conditions. VOCs contribute only a small proportion of the metabolites produced by living organisms, however because of their...
Heart rate variability (HRV) extracted from human physiological turn to be important data as indicators of human health. Originally, HRV calculated and monitored from Electrocardiography (ECG) signal. This research proved that photoplethysmography (PPG) as a simple non-invasive method can measure HRV in motion condition. PPG used Light Photo Sensor (LPS) to capture light reflectance intensity on the...
Copper oxide gas sensor was prepared on silicon wafer by sputtering of copper target at different oxygen flow rate of 0, 4, 8 and 16 sccm using RF magnetron sputtering technique. Argon flow rate, RF power, working pressure and substrate bias voltage were fixed at 50 sccm, 400 W, 22.5 mTorr and −40 V, respectively. The effect of varying the oxygen flow rate towards the time response of the copper oxide...
Harumanis or its scientific name as Mangifera indica is a popular mango in Malaysia due to its unique aroma and taste, despite its expensive price. The high demand for this mango and its potential in export has been the reason why this tropical fruit being a national agenda for the Malaysian government to classify it as the specialty fruit from Perlis (smallest state in Malaysia). As the sole university...
Indoor air quality (IAQ) is a term that describes the air quality of the building occupants. IAQ can be influenced by physical factors like dust particles, chemical or gaseous pollutants (including carbon dioxide, carbon monoxide and volatile organic compounds) and biological factors like molds and bacteria growth which largely depend on temperature and humidity condition of a room. These kinds of...
Zinc oxide (ZnO) is one of the metal oxide semiconductors suitable for use in optoelectronic devices and a potential material for the future solar cell applications. In this works, ZnO films were deposited on silicon and glass substrate by reactive rf magnetron sputtering using a solid Zn target. The influence of the oxygen flow rate and the working pressure on the zinc oxide films microstructure...
Cupric Oxide (CuO) is one of the p-type metal oxide semiconductors that are suitable for use in gas sensing device. The copper oxide thin film was prepared on silicon wafer by sputtering of pure copper target at difference deposition time of 5 min, 10 min and 15 min using RF magnetron sputtering technique. Argon flow rate, oxygen flow rate, RF power and working pressure were fixed at 50 sccm, 8 sccm,...
This paper presents an algorithm to trace an odour plume using swarm robots in laminar airflow. The algorithm proposed here aims to bridge the gap between single and multiple element systems by mimicking and enhancing biologically derived strategies for odor plume tracking. Simulations were carried out on Webots to verify the potential of the algorithm. A simple gas sensor model was introduced to...
Mobile robotics has been strongly linked to localization and mapping especially for navigation purpose. A robot needs a sensor to see objects around it, avoid them and also map the surrounding area. The use of 1D and 2D proximity sensors such as ultrasonic sensor, sonar and laser range finder for area mapping is believed to be less effective since they do not provide information in Y or Z (horizontal...
Yield Prediction is an essential task to be achieved in order to implement effective forward marketing. Forward marketing is a contract that will be signed between supplier and client based on the amount of delivery and the price of delivery in future. To be able to sign such a contract the supplier should be very confident that the yield could be achieved. The yield sustainability is a challenging...
Mango cultivar Harumanis is one of the best table tropical fruit due to its aroma and sweetness. Despite its overwhelming local demand in Malaysia and also internationally, the fruit supply never meets the demand. The flowering phase is identified as an important stage as plant reproductive physiology. Currently, Harumanis mango flowering only happens once a year and this restricts the yield of this...
