In this paper, some novel analytical and numerical techniques are introduced for solving and analyzing nonlinear second-order ordinary differential equations that are associated to some strongly nonlinear oscillators such as a quadratically damped pendulum equation. Two different analytical approximations are obtained: for the first approximation, the ansatz method with the help of Chebyshev approximate polynomial is employed to derive an approximation in the form of trigonometric functions. For the second analytical approximation, a novel hybrid homotopy with Krylov–Bogoliubov–Mitropolsky method is introduced (...) for the first time for analyzing the evolution equation. For the numerical approximation, both the finite difference method and Galerkin method are presented for analyzing the strong nonlinear quadratically damped pendulum equation that arises in real life, such as nonlinear phenomena in plasma physics, engineering, and so on. Several examples are discussed and compared to the Runge–Kutta numerical approximation to investigate and examine the accuracy of the obtained approximations. Moreover, the accuracy of all obtained approximations is checked by estimating the maximum residual and distance errors. (shrink)

Blockchain is one of the technologies that can support digital transformation in industries in many aspects. This sophisticated technology can provide a decentralized, transparent, and secure environment for organizations and businesses. This review article discusses the adoption of blockchain in the ports and shipping industry to support digital transformation. It also explores the integration of this technology into the current ports and shipping ecosystem. Besides, the study highlighted the situation of the supply chains management in ports and shipping domain as (...) a case study in this field. The investigated studies show that blockchain can be integrated into processes such as financial and document workflow. This review contributes to research by focusing on the adoption of blockchain in the ports and shipping industry to support digital transformation. It also aims to understand the existing port practice and map it with current tendencies based on blockchain. This study gives insight analysis to incorporate blockchain technology into ports and shipping processes globally. (shrink)

Cet article rappelle d’abord l’âge d’or de la civilisation arabo-islamique, la dynastie abbasside , pendant laquelle, la traduction joua un rôle capital pour la conservation des produits culturels de l’antiquité et leur transfert de l’Orient vers l’Occident. Puis il décrit la crise de la traduction aujourd’hui, à un moment où les pays arabes ne produisent plus de savoir scientifique et traduisent très peu. Pour illustrer cela, il est fait référence au rapport sur le développement humain dans le monde arabe publié (...) par le Programme des Nations Unies pour le Développement , lequel pointe des faiblesses considérables dans le domaine des sciences et de la technologie. Ce rapport montre que la crise de la traduction est due plutôt aux obstacles politiques qu’aux structures socio-économiques des pays arabes. Il y a un réel problème de gouvernance qui n’encourage pas à bâtir une société de la connaissance.In a first part, this article recalls the golden age of Arab Islamic civilisation, the Abasside dynasty , during which translation played a crucial role for conserving ancient culture and transferring it from East to West. Then, it describes the present-day crisis in translation, a time when the Arab countries no longer produce scientific knowledge and translate very little. To illustrate this, the article refers to the Human Development Report in the Arab World produced by the United Nations Development Programme , which points out considerable weaknesses in the areas of science and technology. It shows that the translation crisis is due more to political obstacles than to socio-economic structures of Arab countries. There is a real problem of governance that does not favour the construction of a knowledge society. (shrink)

This study discusses the impact of different economic indicators on economic stability, including honest leadership, improved infrastructure, revenue generation, and CPEC taking into account the double mediating role of environmental sustainability and sustainable development, while considering the latest COVID-19 situation. This study adopted primary data collection methods and obtained data from the employees of CPEC by using questionnaires and smart-PLS for analysis purposes. The results revealed that honest leadership, improved infrastructure, revenue generation, and CPEC have a positive nexus with economic (...) stability. Despite the severe impact of COVID-19 on the country’s economy, the economic corridor plays a vital role in stabilizing the state’s economy and supports all those related to this phenomenal project either directly or indirectly.
