Research ArticleOpen accessIn the abstractIterative Feedforward Control for Bearing-Free Multibody SystemsNicola Y. Bailey, Christopher Lusty, Patrick S. KeoghAutomated machinery and robotics are commonly conventional multibody systems containing bearing components, which exhibit uncertain, discontinuous and complex tribological characteristics. These generate wear and fundamentally limit the precision of small scale motion due to the tribological effects being difficult to compensate for using model-based active control. However, they can be eliminated through the replacement of traditional bearing joints with flexure … …Journal of Mechatronics and Robotics, Vol. 5, Issue 1 · 6 Dec 2021 · 6,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeep Erosion by Continental Ice Sheets: A Northern Missouri River Drainage Basin Perspective: North AmericaEric ClausenWhile accepting some erosion by continental ice sheets most geologists reject a previously proposed deep erosion by continental ice sheets hypothesis, yet common sense logic suggests continental ice sheets should have eroded much more than they are usually given credit for. Such situations arise in scientific communities when an accepted paradigm cannot adequately explain significant observable evidence. A new and … …Current Research in Geoscience, Vol. 8, Issue 1 · 18 Jan 2019 · 8,889 accessesView PDFCite
EditorialOpen accessIn the abstractIs Rerum® the New Coley's Vaccine?Marco RuggieroColey's Vaccine and Cancer Immunotherapy Dr. William B. Coley is credited for having been the first to translate the observation of an association between bacterial infections, high fever and cancer remission into a successful cancer treatment. However, it is worth noting that such an association dates back to at least one century before Coley's times; as Wiemann and Starnes from … …American Journal of Immunology, Vol. 13, Issue 2 · 31 May 2017 · 12,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality Measurements on the Radio Interface of the Mobile Communication in the Proximity of the Power SystemSaid Ghnimi, Adnen Rajhi, Ali Gharsallah, Fakhreddine KhlifaProblem statement: The electric power lines and its associated equipments generally produce an electromagnetic noise in their environment, which are likely to have dangerous effects on propagation environment to the Global System for Mobile communication (GSM) cellular mobile network. Approach: In this study, we analyzed the characteristics of the power line noise and its correlation with the GSM burst; showing … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 26 Mar 2015 · 7,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractHOW PUBLIC ORGANISATIONAL STRUCTURES INFLUENCE SOFTWARE DEVELOPMENT PROCESSESMohammed A. Bindrees, Robert J. Pooley, Idris S. Ibrahim, Diana S. BentalSoftware applications are developed differently based on each organisation's needs and requirements. Software projects are fundamentally based on three considerations (time, cost and quality) each of which is affected by organisational factors. Both Project Management and Software Engineering have emphasised the role of organisation structure on the quality of the deliverable software applications, recognising that organisation structure influences flexibility, reporting … …Journal of Computer Science, Vol. 10, Issue 12 · 29 Dec 2014 · 7,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Survey of Intrusion Detection Schemes in Wireless Sensor NetworksMurad A. Rassam, M. A. Maarof, Anazida ZainalWireless Sensor Networks (WSNs) are currently used in many application areas including military applications, health related applications, control and tracking applications and environment and habitat monitoring applications. The harsh and unattended deployment of these networks along with their resource restrictions makes their security issue very important. Prevention-based security approaches like cryptography, authentication and key management have been used to protect … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 17 Aug 2012 · 8,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractReligion and Schools in a Liquid WorldFrank PetersThis study is an exploration of the changing contexts within which schools are required to function. As global borders have become more porous schools are challenged to deal with students from increasingly diverse cultural, linguistic and religious backgrounds, frequently in a political context that is explicitly secular or nondenominational. This perspective may not be perceived by all to be as … …Journal of Social Sciences, Vol. 8, Issue 3 · 10 Aug 2012 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Pass Band Filter in Hybrid Architecture Planar/Non-Radiative Dielectric Waveguide Integration TechnologyGharssallah Ali, Harizi HanenProblem statement: The expansion of RF, microwave and millimeter devices has revolutionized today’s ommunication and sensor systems. Low-cost, high-performance and mass producible millimeter wave technologies are vital for commercial broadband systems. Challenging issues are commonly faced in the design of low-loss integrated circuits for example high-Q band pass filter, which the planar technique is fundamentally limited in performance. Approach: In … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 10 Aug 2012 · 7,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrammatical Relation Extraction in Arabic LanguageOthman Ibrahim Hammadi, Mohd Juzaiddin Ab AzizProblem statement: Grammatical Relation (GR) can be defined as a linguistic relation established by grammar, where linguistic relation is an association among the linguistic forms or constituents. Fundamentally the GR determines grammatical behaviors such as: placement of a word in a clause, verb agreement and the passivity behavior. The GR of Arabic language is a necessary prerequisite for many natural … …Journal of Computer Science, Vol. 8, Issue 6 · 17 Mar 2012 · 7,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractApproaches to Learning in First Year University PhysicsRachel Wilson, Steve Georgakis, Manjula SharmaProblem statement: In recent decades, discipline specific ways of thinking and knowing have gained increased recognition in understanding learning. However, there has been little empirical research examining student approaches to learning within specific disciplines or, even more specifically, within different streams of study or in response to different curriculum within a discipline. Approach: The aim of this study was to … …Journal of Social Sciences, Vol. 8, Issue 2 · 25 Feb 2012 · 9,219 accessesView PDFCite
