Research ArticleOpen accessIn the abstractStrengths and Weaknesses of Digital Maturity ModelsAbdoulaye Sadio Barry, Saliha Assoul, Nissrine SouissiAssessing digital maturity is a prerequisite for any digital transformation initiative. This assessment allows the business to know its current level of digital maturity and assess its ability to manage change. The evaluation also enables society to identify the main thrusts and objectives of its digital strategy. This article analyses the strengths and weaknesses of 8 digital maturity models to … …Journal of Computer Science, Vol. 19, Issue 6 · 31 May 2023 · 6,962 accessesView PDFCite
Review ArticleOpen accessIn the abstractBritish Airways is Ordering up to 42 Boeing 777-9s Aeronaves to Modernize the UK Flag Carriers Long-Haul FleetRelly Victoria Virgil PetrescuThe Boeing 777 (sometimes referred to as Triple 7) is a large-capacity subsonic long-haul bomber aircraft built by the American company Boeing. This type of aircraft holds the current record of autonomy for commercial jets (17,450 km without food). Other special features of the aircraft include the perfect circular fuselage, a set of six wheels on each axle of the … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 19 Feb 2020 · 7,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Dual Exponentiated Weibull ModelMona Mustafa ElbielyA new lifetime model with various shapes of the hazard rate function for modeling uni-modal and bimodal data sets is introduced and studied along with its statistical properties. Before using the maximum likelihood method for estimating the unknown model parameters, we assessed its performance via a simulation study. The flexibility of the new model is illustrated via plots of the … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 29 Jun 2019 · 6,511 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Stability Analysis in a Two-Step Reactive Cylindrical StockpileR.S. Lebelo, R.K. Mahlobo, K.C. MoloiThermal stability analysis in a cylindrical stockpile of reactive material undergoing a two-step low-temperature oxidation reaction is studied in this article. The reactant consumption in this case is neglected and heat transfer with thermal stability are investigated by application of the energy equation. The complicated combustion process results with nonlinear interactions and hence the nonlinear partial differential equation governing the … …American Journal of Applied Sciences, Vol. 15, Issue 2 · 6 Dec 2017 · 7,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractPorosity Analysis in Porous Brass Using Dual ApproachesRyan Yeargin, Rob Ramey, Cindy WatersThe goal of this research is to produce porous samples for various applications such as heat exchangers, filters and radiation shields. The level of porosity is an important objective yet the level of confidence in two main methods (hand calculations and microscopic analysis) is not high. This work will compare porosity values obtained from traditional hand calculations against analysis from … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,525 accessesView PDFCite
