Research ArticleOpen accessIn the keywordsThe Effect of Temperature on the Performance of Uncooled Semiconductor Laser Diode in Optical NetworkMohammad Syuhaimi Ab-Rahman, Nurain Izzati ShuhaimiProblem statement: The characteristics of a laser diode are highly dependent on the temperature of the laser chip. Thus, the effect of temperature on the network performance of uncooled semiconductor laser diode are studied by simulating its equivalent electrical circuit, developed from the rate equations that governing optical components directly into an electrical simulation framework. Approach: The simulations are carried … …Journal of Computer Science, Vol. 8, Issue 1 · 29 Oct 2011 · 7,685 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThermo Optical Properties and Related Electronic Polarizabilities of MoO3 Thin Films Using EllipsometryZahid HussainThermo optical properties are reported for thermally evaporated MoO3 thin films using ellipsometry. The values of TOCs: dn/dT and dk/dT relating to MoO3 thin films are found to be negative and positive, respectively over the temperature range 295-460 K and also are found to have the same trend over the range 120-300 K, and have values of the order of … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 1 Apr 2019 · 7,571 accessesView PDFCite
Review ArticleOpen accessIn the abstractIOT-Based Smart Helmet for COVID-19 Detection and ManagementFoziah GazzaweCovid-19 is one of the pandemics that has shocked the world. Having originated from China, the virus rapidly spread across many countries of the world. There was a need to come up with mechanisms to manage the spread of the virus. The traditional methods of temperature capture through thermal handheld gun thermometers were tedious and exposed the officers to the … …Journal of Computer Science, Vol. 19, Issue 11 · 14 Nov 2023 · 6,046 accessesView PDFCite
Review ArticleOpen accessIn the abstractRecent Advances in Point of Care Diagnostic Tools: A ReviewLaura Wessels, Haider RaadGlobally, there is a great need for portable, inexpensive diagnostic tools that can provide quick, accurate results using relatively small sample volumes. Point-Of-Care (POC) measurements of human saliva, sweat and/or blood capable of detecting glucose levels, foreign pathogens such as bacteria, fungi and many different viruses (HIV, Ebola, Influenza, etc.) that use microfluidics and optofluidics are close to commercial availability. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 28 Nov 2016 · 8,234 accessesView PDFCite
