In this article, the growth of aerodynamic efficiency and the growth of the wing structural stress is studied for DLR-F4 typical transport aircraft wing-body, after installing classical Whitcomb winglets of different configurations and a delta wingtip fen... see more

The aim of this paper is to describe the largest inscribed circle into the fundamental domains of a discontinuous group in Bolyai-Lobachevsky hyperbolic plane. We give some known basic facts related to the Poincare-Delone problem and the existence notion ... see more

The depletion of fossil fuels and the worsening environment motivate engineers and researchers to explore renewable energy resources. One of the promising renewable energy is wind energy. The wind turbine extracts wind energy to generate electricity. This... see more

The bound state solutions of the deformed Klien-Gordon equation have been determined in the three-dimensional extended relativistic quantum mechanics 3D-ERQM symmetries using position-dependent mass (PDM) with unequal scalar and vector potential for the i... see more

Pada proses desain kapal WISE sangat diperhatikan masalah gaya hambat serta gaya angkat yang terjadi saat kapal melaju dalam mode ground effect. Salah satu cara untuk mengurangi gaya hambat kapal WISE adalah dengan meningkatkan nilai aspek rasio sayap dan... see more

Unmanned Aerial Vehicle adalah pesawat yang tidak membutuhkan operator manusia didalamnya. Salah satu faktor desain yang penting dalam perancangan UAV adalah bentuk geometri dari pesawat tersebut. Pada daerah sayap pesawat yang memiliki panjang yang terba... see more

Kinerja pesawat sangat dipengaruhi oleh bentuk geometri dari pesawat tersebut dan juga penambahan geometri lain pada salah satu bagiannya. Winglet merupakan salah satu komponen yang ditambahkan pada pesawat yang berfungsi untuk mengurangi timbulnya wingti... see more

In this paper, we present two gyroarea formulas (Möbius-Bretschneider’s formula and Möbius-Cagnoli’s formula) for Möbius gyroquadrilaterals in the Poincaré disc model of hyperbolic geometry.
