Research ArticleOpen accessIn the keywordsComparison of 10 cm and 50 cm Long Iodine Cells in Iodine-Stabilized Diode Laser-Pumped Nd:YAG Laser at 532 nmPrayut Potirak, Monludee Ranusawud, Pichet Limsuwan, Prathan BuranasiriAn iodine-stabilized diode laser-pumped Nd:YAG laser system at 532 nm was developed at the National Institute of Metrology of Thailand (NIMT) for the first time in Thailand. Two iodine cells with the lengths of 10 and 50 cm were used for the comparison of frequency stability of Nd:YAG laser. The experiment was set for phase modulation spectroscopy. The Nd:YAG laser … …American Journal of Applied Sciences, Vol. 15, Issue 5 · 26 May 2018 · 7,886 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Low Frequencies on Three Phase Induction Motor Performance Operating in Close Proximity to Rated SpeedQazem Jaber, Qais Naman, Mahdi ShamaseenVariable speed drives (VSD) are adhered to induction motors in most of the present industrial applications. And since the world has become more conscientious to energy saving, inverters established them selves in domestic buildings and industry. Square wave inverters generate dominant harmonics of the 5th, 7th, 11th and 13th order. Inverters based on PWM strategy produce much higher harmonic order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Wireless Sensor Node Supporting Various Powers Supply and Communication MethodsStefan Gruber, Hannes Reinisch, Hartwig Unterassinger et al.Problem statement: This study presents a wireless sensor node dedicated for in-tire pressure and temperature monitoring. Additional features set it apart from the many different systems available on the highly competitive market. State-of-the-art implementations are mounted on the rim of a tire. Here the sensor node will be mounted on the inner liner of the tire. By moving the sensor … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 8,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Multi Task Analysis Model Based on EEG Features in the Study of the Correlation between Depression and Sleep Disorders in College StudentsFeng MaWith the improvement of multi-modal technology, research on depression recognition combining multiple biological signal features has been increasing. Electroencephalogram signals reflect brain activity, and by analyzing their characteristics, the accuracy and stability of depression recognition can be effectively improved. Therefore, this study proposes a correlation analysis between depression and sleep disorders in college students based on electroencephalogram feature analysis, innovatively … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 2 Feb 2026 · 1,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Ultrasonication on Milk Fat Globule Size and Inhibition of Salmonella enteritidis GrowthUmiatin Umiatin, Dalia Sukmawati, Taryudi Taryudi et al.One significant effect of ultrasonic treatment is the inactivation of microorganisms. This characteristic causes ultrasound to be widely used in food processing, healthcare devices, and water treatment. Ultrasonication is an innovative technology that holds promise for accelerating processes and producing high-quality products. The ultrasonic process in milk processing includes homogenization and sterilization. Milk homogenization standardizes fat globule size, while sterilization … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 8 May 2026 · 1,507 accessesView PDFCite

Research ArticleOpen accessIn the abstractDynamical Analysis on the Transmission of Pertussis with Maternally Derived ImmunityAisha Aliyu Yakubu, Farah Aini Abdullah, Ahmad Izani Md Ismail, Yazariah Mohd YatimA susceptible-infected-recovered compartmental model incorporating maternally derived immunity compartment is analyzed in this study. The stability of the pertussis-disease-free and endemic equilibrium is studied. The basic reproduction number is obtained and its behavior analyzed by varying parameters. Numerical simulations indicated that when the waning parameter is increased, the frequency at which the population attains stability varies. However, the infected population … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 26 Jun 2020 · 6,294 accessesView PDFCite
