Research ArticleOpen accessEvery word in the titleDesign and Analysis of SRAM Cell for Smart ApplicationPushkar Praveen, Rakesh Kumar SinghIn today's circuittechnology, power consumption and savings are key concerns. The driving reasonsbehind these innovations are portable devices that require high throughput andlow power dissipation, such as computers, phones, and Personal DigitalAssistants (PDAs). In portable devices, reducing or decreasing IC dissipatedpower through design optimization is a big problem, and restricted batterylifespan places very severe restrictions on overall power usage. In … …Journal of Computer Science, Vol. 18, Issue 9 · 17 Sep 2022 · 5,726 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign and Analysis of a Lunar Lander's Landing SystemAnurag Talekar, Ajinkya Dabholkar, Ajinkya Thombe et al.In the overall design and performance prediction of spacecraft intended to accomplish delicate landing on the moon, touchdown dynamics analysis during the landing phase is one of the most important task. Missions in the past have experienced toppling of the lander due to the surface on the lunar body being covered with dead volcanoes and impact craters that restrict the … …Journal of Aircraft and Spacecraft Technology, Vol. 5, Issue 1 · 28 Jun 2021 · 9,976 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of Interaction Design Patterns on Drawing Application for Early Preschool Children using Inductive Approach (Case Study: ABC Coloring Book for Toddlers and Tracer-hand Writing Pattern Drawing Application)Indah Mekar Sari, Dana Sulistiyo Kusumo, Mira Kania SabariahNowadays, there are many game applications that are used as a medium of interactive learning for children. One of them can help early preschool children to learn drawing. Using interaction data, we conducted an inductive approach to identify children's interaction patterns on drawing applications. We observed the used of two drawing applications: "ABC Coloring Book for Toddlers" and "Tracer-Hand Writing … …Journal of Computer Science, Vol. 13, Issue 12 · 13 Dec 2017 · 7,575 accessesView PDFCite

Approach: The research method for the present study was comparative analysis. Results: The first base was rejection of objective view toward the universe and accepting … …Journal of Social Sciences, Vol. 8, Issue 3 · 26 Mar 2012 · 8,065 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign Analysis of High-Speed Axial-Flux GeneratorM. Sadeghierad, A. Darabi, H. Lesani, H. MonsefProblem Statement: Axial flux permanent magnet machines are regarded as compact high efficiency generators for micro-turbines employed in the distributed power generation systems. High-speed rotor of the generator causes some designing and modeling problems. Sensitivity analysis tasks of the machine parameters are difficult and completely different in comparison with the problems associated with conventional machines. Approach: This article presents a … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,559 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign, Development and Numerical Analysis of Honeycomb Core with Variable Crushing StrengthShabnam Sadeghi Esfahlani, Hassan Shirvani, Ayoub Shirvani et al.A honeycomb core with half-circular cut-away sections at the spine (the adjoining cell walls) is designed and developed and numerically tested under axial dynamic load condition. The parametric study is invoked to identify the effect of various circular cut-away dimensions.
