Research ArticleOpen accessIn the abstractWellbore Surveying While Drilling Based on Kalman FilteringMahmoud ElGizawy, Aboelmagd Noureldin, Jacques Georgy et al.Problem statement: Oil and gas are global fuels obtained primarily from drilling wells in underground terrestrial reservoirs. Vertical drilling is preferred because of its simplicity and therefore low cost, but subsurface targets can often be procured only by directing the wellbore along predefined non-vertical trajectories. For instance, directional drilling must be employed to reach locations inaccessible to the drilling rig, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,577 accessesView PDFCite
Research ArticleOpen accessIn the abstractFiber Optic Sensors for Transportation Infrastructural Health MonitoringChin Chang, Rahul MehtaProblem statement: Monitoring the health of transportation infrastructures is currently reliant on transportation maintenance teams. Scheduled and periodic inspections on most of the infrastructures are performed by manual and visual operations, which are generally time consuming and costly procedures. The use of the fiber optic sensor technology makes it possible to realize continuous, real time and automatic health monitoring for … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware Implementation of Higher Throughput Anti-Collision Algorithm for Radio Frequency Identification SystemJahariah Sampe, Masuri OthmanThis paper presents a proposed hardware implementation of Higher Throughput Anti-Collision Algorithm (HTACA) for Radio Frequency Identification (RFID) system. Our proposed HTACA combines a pipeline and a deterministic anti-collision technique in order to enhance its performances. These downlink and uplink operations are concurrently executed during the identification process. The downlink operation is purposely pre-selected a group of tags base on … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,443 accessesView PDFCite
Research ArticleOpen accessIn the abstractWork Performance of MB Trac 900 Tractor on Mountains Terrain in TurkeyTolga Ozturk, Murat DemirThe forestry works mainly involves such various stages as growing, protection, production, wood harvesting, marketing and utilization of forest products. Wood harvesting is performed by completion of cutting, extraction and transporting stages. The most obvious feature of wood harvesting is that the operations are done under various weather conditions open in the field. The measurements and observations were made on … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,314 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordBio-Inspired Materials: Exhibited Characteristics and Integration Degree in Bio-Printing OperationsAntreas KantarosIn the last decade, additive manufacturing techniques, commonly known under the term "3d printing" have seen constantly increasing use in various scientific fields. The nature of these fabrication techniques that operate under a layer-by-layer material deposition principle features several de facto advantages, compared to traditional manufacturing techniques. These advantages range from the precise attribution of pre-designed complex shapes to the … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 29 Nov 2022 · 7,180 accessesView PDFCite
