Review ArticleOpen accessIn the abstractAbout Boeing X-32Relly Victoria Virgil PetrescuThe Boeing X-32 is a demonstration jet designed for the Joint Strike Fighter contest. He lost the Lockheed Martin X-35 demonstrator, which was further developed in the Lockheed Martin F-35 Lightning II. Boeing's competitive advantage has been to provide considerably lower costs of production and lifecycle by minimizing variations between different versions of the JSF. Therefore, the X-32 was designed … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 1 Apr 2019 · 9,969 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransformable Curved Thin Glass GreenhouseLaura GaluppiThe use of new generation thin, lightweight and damage-resistant glass, originally conceived for electronic displays, is being very recently proposed for structural applications, in particular for adaptive and movable skins and façades. This paper explores this concept and presents a study on the structural use of thin glass in greenhouses for protected agriculture, based on the use of cold-twisted elements … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 1 Dec 2018 · 6,810 accessesView PDFCite
Review ArticleOpen accessIn the abstractSome New Gears AspectsFlorian Ion Tiberiu PetrescuIn today's mechanical transmissions most widely used, the gears, are spread across all industries. For this reason, their importance has become overwhelming, which is why we want to recall in this paper some important aspects regarding toothed wheels. It is the geometry, cinematic, the forces and the yields of these mechanisms, which will be presented in the work in the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 7,080 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Impacts of Sustainable Dairy Farming in Char Areas of Northern BangladeshJasim Uddin Ahmed, Shankar Kumar Raha, Md. Habibur RahmanThis study was conducted to evaluate the potential impacts of sustainable dairy farming in Char areas of Northern Bangladesh. A total of 600 poorest dairy farming households were selected out of 1323 households, taking 200 households from each Upazila of Sariakandi, Islampur and Belkuchi of Bogra, Jamalpur and Sirajganj districts, respectively using simple random sampling technique. A structured questionnaire was … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 3 · 2 Nov 2017 · 8,544 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurface Level Estimator-An Automated Contouring InstrumentVarun Sai Chinthala, Gajendra DixitThis paper introduces a dynamic electronic instrument to measure the inclination of a surface, named as Surface Level Estimator (SLE). This device is designed to reduce the human effort and time consumed for civil surveying. This paper describes the construction, working principle, programming and experimentation results of the instrument. Finally, the conclusion and scope of future is discussed at the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 6 Sep 2017 · 7,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimum Design and Cost Characteristic of Small ConveyorSuwat Nanetoe, Nitipong SoponpongpipatAlthough there are many works dealing with the economic analysis of a long conveyor, the information about a short conveyor is insufficient. This study, thus, deals with the short conveyor by studying the effect of belt width, belt length, convey capacity, and conveyor inclination angle on the cost characteristic of short conveyor. The study was done by calculating the conveyor … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 4 Jan 2013 · 7,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of the Geometrical Parameters of a Solar Bubble Pump for Absorption-Diffusion Cooling SystemsN. Dammak, B. Chaouachi, S. Gabsi, M. BourouisProblem statement: The objective of this study was to optimize the geometrical parameters of a bubble pump integrated in a solar flat plate collector. Approach: This solar bubble pump was part of an ammonia/water/helium (NH3/H2O/He) absorption-diffusion cooling system. Results: An empirical model was developed on the basis of momentum, mass, material equations and energy balances. The mathematical model was solved … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Geometry and Orientation on Flank Insolation of Streets in an Arid Climate CityMehrdad Mazloomi, Ahmad Sanusi Hassan, Parmis Naraghi Bagherpour, Mohd Rodzi IsmailProblem statement: Whilst at the design stage the various aspects of design impact must be taken into account, the incident solar radiation, insolation, is a key to many environmental aspects of street canyons. In this regard, the configuration of an urban street has a decisive role in magnitude of the solar radiation which it receives on its flank. This study … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 9,006 accessesView PDFCite
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 · 8,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of the Cuttings Cleaning During the Drilling OperationHussain H. Al-Kayiem, Nadia Mohd Zaki, Muhamad Z. Asyraf, Mahir Elya ElfeelProblem statement: Oil well cleaning is the ability of a drilling fluid to suspend and transport drilled cuttings from the down hole (bit face) to the surface. The cleaning performance was affected by many factors such as fluid viscosity, annular flow velocity, angle of inclination and drill cuttings size and shape and. Approach: Navier-Stoke equations, the continuity equation and the … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,257 accessesView PDFCite
