Ultraviolet-Visible (UV-VIS) spectroscopy is a technique used to measure the intensity of light absorbed after passing through sample solution. UV-VIS analyses samples using within ultraviolet and visible wavelength ranges. Compared other methods, this non-invasive less complex. However, current spectrometers are often bulky not portable. Therefore, objectives research design portable Arduino-based system for liquid-based solutions integrate motorised XY-axis into proposed system. The setup...
Under-nutrition in neonates is closely linked to low body fat percentage. Undernourished are exposed immediate mortality as well unwanted health impacts their later life including obesity and hypertension. One potential cost approach for obtaining direct measurements of near-infrared (NIR) interactance. The aims this study were model the effect varying volume fractions melanin water skin over NIR spectra, define sensitivity reflection on changes thickness subcutaneous fat. GAMOS simulations...
This research paper describes the effects of rain attenuation on free space optical (FSO) transmission system. The entire was conducted in heart Kuala Lumpur city- year 2001, as city using such systems (LAN-to-LAN & WLAN-to-WLAN) widely to connect metropolitan areas for data transmission. preliminary experiments were done PAVLight product modeled PL-1G/1Tx/GigE which leaded maximum reach 700m distance with 810nm wavelength and also laser power 14dBm. intensities obtained from measuring unit...
This article presents the effects of haze attenuation on Radio over Free Space Optic (RoFSO) transmission system in KLIA Sepang, one towns Malaysia. The condition which affects FSO link transmissions was considered October 2015 and 2017 at Sepang referring to reading record Air Pollution Index (API). In this paper, OptiSystem simulation software is used as a preliminary study before configuring real RoFSO setup. We model by converting radio frequency (RF) signal into light where source...
Abstract Under-nutrition in neonates can cause immediate mortality, impaired cognitive development and early onset adult disease. Body fat percentage measured using air-displacement-plethysmography has been found to better indicate under-nutrition than conventional birth weight percentiles. However, equipment is expensive non-portable, so not suited for use developing communities where the burden often greatest. We proposed a new body measurement technique length-free model with...
Fiber-based surface plasmon resonance (SPR) sensors are the ideal configuration for rapid and label-free biomolecule detection. Gold-coated tapered optical fiber was used to excite SPR mode that propagates at metal–dielectric interface. By forming self-assembled monolayers (SAMs) of active chemical functional groups, deoxyribonucleic acid (DNA) probe targeting secY gene Leptospira immobilized onto sensor surface. Red shifts in wavelengths were observed different concentrations leptospiral...
Low fat composition in newborns exposes them to an immediate risk of increased mortality and morbidity, inhibited physical cognitive development diabetes obesity diseases later life. Information about nutritional dietary status can be accessed by measuring the amount body. The functions subcutaneous involve energy storage, thermo-insulation a buffer. Current technologies for newborn body monitoring are: device based on air displacement plethesmography (PeaPod), dual-energy Xray, underwater...
This work reports the enhancement of a single-mode tapered optical fiber (TOF) sensor for Dengue virus (DENV) II E protein using chitosan. Chitosan, an organic nanomaterial with excellent biocompatibility and abundant binding sites, was deposited on TOF as intermediate layer between activated taper surface anti-DENV antibodies. The best DENV sensing performance attained at chitosan thickness 17.13 nm, which attributed to optimum balance auxiliary penetration depth evanescent field. An...
While other studies into sensing the thickness of subcutaneous fat have configured axes both source and detector to be at a 90-degree angle surface being measured, we introduce source-detector set up 45-degree angle. We apply Gamos computer simulation ex-vivo phantom experiment compare near infrared response between position angles 930 nm. A single layer is used as sample with 1 mm 15 in intervals simulations while experiments from 3 utilising ground beef fat. Near intensities exhibit...
