A feasibility study of using an Electronic Nose as a fruit ripeness measuring instrument
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-14)
This paper presents the study of using an artificial olfactory system as a nondestructive instrument to measure fruit ripeness. The cultivar chosen for this study is Harumanis mango. This system comprises of an array of ...
Fabrication of a Hand-held Electronic Nose
(Universiti Malaysia Perlis, 2007)
An electronic nose is a device that performs the electronic olfactory to substitute human experts. The development of these devices is growing faster due to higher demand. However, current electronic noses usually are very ...
Development of multichannel artificial lipid-polymer membrane sensor for phytomedicine application
(MDPI, 2006)
Quality control of herbal medicines remain a challenging issue towards integrating phytomedicine into the primary health care system. As medicinal plants is a complicated system of mixtures, a rapid and cost-effective ...
Entrepreneurial Education for Engineers
(Association for Engineering Education in Southeast and East Asia and the Pacific, 2003-12-08)
Numerous discussions by members of the academia and the industry about the quality of education provided for engineers of the future show that insufficient provision of certain skills and areas of knowledge seems prevalent. ...
Correlation studies between electronic nose response and headspace volatiles of Eurycoma longifolia extracts
(Elsevier B.V., 2006-12)
Most herbs have their own characteristic smell due to the presence of volatile compounds. Traditionally, volatiles are analyzed by using sophisticated and expensive gas chromatography (GC) in tandem with a selective mass ...
Transient parameters of a coated quartz crystal microbalance sensor for the detection of volatile organic compounds (VOCs)
(Elsevier B.V., 2005-09)
A PVC blended lipid membrane coated quartz crystal microbalance has been prepared to mimic human olfaction system. Transient response curves of the sensor on exposure to methanol, ethanol, chloroform, acetone and benzene ...
Taste profiling of Centella Asiatica by a taste sensor
(MYU K.K., 2003)
A taste sensor was used for organoleptic profiling and quality evaluation of Centella asiatica extracts and isolates on the basis of basic tastes i.e., sweet, sour, bitter, salty and umami. The sensor uses an array of ...
Quantitative analysis of Orthosiphon stamineus benth with a disposable sensor trip
(Alpha M.O.S, 2007-05-05)
A disposable screen printed array sensor strip based on self-plasticized lipid membrances combined with chemometric algorithm has been developed and applied for quantification of Orthosiphon stamineus benth extracts. ...
Redesign the 4:2 compressor for partial product reduction
(International Association of Science and Technology for Development (IASTED) / ACTA Press, 2007)
In this paper, we attempt to redesign the 4:2 compressors. Since its inception by Weinberger in 1981[1], this concept of compressor has been used in most digital multiplications and multi operand operation scheme. The ...
A voltage reference circuit for current source of RFIC blocks
(Emerald Group Publishing Limited, 2008)
Purpose - The purpose of this paper is to design a voltage reference circuit for current source of radio frequency integrated circuit blocks. The voltage reference circuit is called voltage for current source (VCS). ...
