The understanding of the performance of a propeller in realistic operative conditions is nowadays a key issue for improving design techniques, guaranteeing safety and continuity of operation at sea, and reducing maintenance costs. In this paper, a summary... see more

The process of applying a polymer thermoplastic material in the 3D printing process using the FDM technology (Fused Deposition Modeling) was investigated. The object of study was the discrete layer of the prototype. To determine the geometric parameters, ... see more

During the past few years, new developments have occurred in the field of 3D photogrammetric modeling of culture heritage. One of these developments is the expansion of 3D photogrammetric modeling open-source software, such as VisualSfM, and cost-effectiv... see more

The aerodynamics of contra-rotating propellers is a complex three-dimensional problem of an unsteady flow, which is often approached by assuming numerous simplifications. Presented computational model combines a 3D panel method with a force-free vortex wa... see more

The aim of this paper is to investigate the possibility of drone optimization by selecting and testing the best material suitable for additive manufacturing technology and generative design approach, i. e. shape optimization. The use of additive manu... see more

Recently, a number of research groups have paid much attention to the study of Floating Offshore Wind Turbines (FOWTs). Similar to other offshore structures, the FOWTs are subjected to irregular waves and wind loads which cause a dynamic response in the s... see more

The success of the Marine Corps organization depends on the ability of its personnel to respond positively and overcome environmental challenges, acquire the new required skills, take official orders assiduously, and exhibit the adaptive performance from ... see more

En la actualidad, existen varios procedimientos contrastados y algunas otras propuestas [1]para realizar la autoevaluación de ejercicios o exámenes de materias que se evalúan mediante ejercicios numéricos. Se comparan los valores intermedios o finales y s... see more
