Research ArticleOpen accessEvery word in the titleThe Effects of Oil Film Shape on Piston Ring and Liner Tribology Under Mixed LubricationAbbas Razavykia, Cristiana Delprete, Eugenio Brusa, Yaser HosseiniMechanical power loss reduction at lubricated reciprocating and rotating components is recognized as an approach to improve the efficiency and to reduce the emissions of Internal Combustion Engines (ICEs). To achieve these goals, the instantaneous investigation of lubrication characteristics is required. Piston ring pack is of paramount importance as it is known as major contributor to frictional losses and energy … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 10 Nov 2021 · 6,523 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn Containment and Radical Graphs of a Commutative RingSaba Al-KaseasbehIn this study, we consider various graphs with the vertices being sets of ideals of a commutative ring with identity, R. How we define the edge set will vary according to distinct ideal theoretic properties. We apply a graphical approach to the study of ideal relationships in commutative rings and from this we obtain some properties of their graphs. …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 29 Dec 2016 · 7,266 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRice Grain Moisture Determination Using Microstrip Wide-Ring and Microstrip Coupled-Line SensorsHou Kit Mun, Kok Yeow You, Mohamad Ngasri DimonDetermining the Moisture Content (MC) inside rice grain is an important element for grain processesing such as harvesting, storage, quality control and transportation. A microstrip wide-ring sensor and a microstrip coupled-line sensor with low insertion loss were developed to operate at relatively low frequency to determine the MC and relative complex permittivity of rice grain. The complex permittivity for rice … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 3 Apr 2015 · 7,438 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Doping Position on the Active Silicon-on-Insulator Micro-Ring Resonator Based on Free Carrier InjectionB. Mardiana, Sahbuddin Shaari, P. Susthitha Menon et al.Problem statement: Metal interconnects have become significant limitation on the scaling of CMOS technologies in electronics integrated circuit. Silicon photonics has offers great potential to overcome this critical bottleneck due to the advantages of optical interconnects. Silicon-based optical micro-ring resonator is promising basic element of future electronic-photonic integrated circuits because of its wide applications on photonic devices such as modulator, … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 9 Aug 2012 · 7,342 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFlexible Topology Migration in Optical Cross Add and Drop Multiplexer in Metropolitan Ring NetworkMohammad Syuhaimi Ab-RahmanProblem statement: Optical Cross Add and Drop Multiplexer (OXADM) is a recently invented optical networks device. Approach: A design with a purpose to combine the operational concepts of Optical Add-Drop Multiplexer (OADM) and Optical Cross Connect (OXC) has been developed. It is developed by studying the drawbacks in existing devices and with some excellence features added. OXADM is introduced to … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,635 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemark on Bi-Ideals and Quasi-Ideals of Variants of Regular RingsSamruam Baupradist, Ronnason ChinramProblem statement: Every quasi-ideal of a ring is a bi-ideal. In general, a bi-ideal of a ring need not be a quasi-ideal. Every bi-ideal of regular rings is a quasi-ideal, so bi-ideals and quasi-ideals of regular rings coincide. It is known that variants of a regular ring need not be regular. The aim of this study is to study bi-ideals … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 25 Mar 2011 · 6,953 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerically Studying the Effect of Stiffening Rings on Reducing the Thickness of Torospherical Heads under Pressure on Their Concave SideSa'id Golabi, Ali Ghorbanpour-Arani, Arash ZamaniThe high thickness of heads used in pressure vessels is always one of the main concerns of designers and manufacturers. A thorough study has been conducted on all types of heads including torospherical heads, with external and internal pressure to reduce their thickness using stiffening rings by finite element technique. Here the result of analysis on heads with pressure on … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,146 accessesView PDFCite
