This quantity depends mainly on factors such as wind resource characteristics, type, number and arrangement of turbines. For areas with complex terrain, wind resource characteristics depend largely on terrain features, so the selection of turbine installation locations is very important. Because when the turbines operate, they will cause a wake effect that increases the turbulence of the flow behind. Therefore, it is necessary to find the optimal distance between turbines so that the annual energy production reaches the maximum value. This study presents a method to determine the optimal turbine locations when considering the correlation between wake loss and turbine space in the case of mountainous terrain. Firstly, a computational fluid dynamics model combined with a geographic information system are used to determine the 3-dimensional wind characteristics at specific locations. Secondly, a Jensen model is used to consider the wake effect according to the distance between turbines. Then, the the annual energy production values are determined through the analytical model. In addition, a comprehensive assessment of levelized cost of energy is also provided to confirm the practicality of implementing the optimization model. Finally, the optimal location configuration of the turbines is proposed. This method was tested and compared with a farm with sufficient data to assess reliability and then applied to an area in Ninh Thuan, Viet Nam. The results showed that the the annual energy production obtained from this farm.

De La Abstract: The growing complexity of industrial automation requires advanced design methodologies that integrate mechanical, electronic, and software systems into cohesive mechatronic products. This paper introduces an innovative engineering design methodology focused on the development of mechatronic products, covering from ideation to embodiment design. For its validation, the methodology was applied in a case study involving the design of a construction robot that automates key tasks such as block transportation, mortar application, and block placement. The robot was designed using a modular approach, allowing for scalability and adaptability to various tasks within the construction environment. To evaluate the methodology’s effectiveness, a comparative assessment was conducted using five key criteria: Iterative Process, Multidisciplinary Work, Design Complexity, Usability, and Adaptability. The proposed methodology scored 3, 3, 3, 2, and 2 respectively, on a 0-3 scale, demonstrating strong performance in early- stage iteration, cross-disciplinary integration, and handling of complex designs, with moderate usability and adaptability. These results position the methodology among the most balanced approaches, bridging both classical and modern design methods, such as those proposed by Ulrich or the V-model. Initial validation of this case study, through simulations and conceptual design, highlights the robot’s potential to improve efficiency and reduce labor costs. Although the case study targets construction, the methodology is adaptable to various industrial contexts, particularly manufacturing processes requiring automation, modularity, and flexibility. Future work includes the development of a physical prototype and further validation, with the potential to expand the methodology to broader manufacturing environments, fostering human-robot collaboration and adaptive production systems.

Nowadays, manufacturing systems are more frequently exposed to disturbances and risks that affect their everyday operations. Hence, it is imperative to analyze and design proactive and reactive strategies to respond to those disruptive events. While there has been an increasing interest in tackling risks from the supply chain perspective, an analysis of risks from the manufacturing system view has been neglected. Risks are broadly classified into operational risks and disruption risks. This study presents a literature review of different manufacturing paradigms and what operational risk considerations have been discussed for each stage of the manufacturing life cycle. The review further analyzes how manufacturing systems are trying to handle disruption risks. Additionally, the article maps the different manufacturing systems and the strategies implemented to the different adaptability facets. Finally, the paper discusses managerial insights and possible research avenues.

It is provided by testing the system by an independent laboratory. Such an evaluation gives to the customer certainty that the system or product is secure enough for the intended use. In this paper we discuss the security assurance that the automotive sector requires to the 5G network for the secure communication of the Intelligent Transport System applications. In this case, the automotive sector takes the role of the customer of the network operator that provides connectivity of cars, trucks, bicycles, pedestrians and traffic infrastructure for creating vehicle to everything platform. Concretely, in this paper we (1) show new methodologies for evaluating network security, (2) provide a new strategy for the customer (automotive company) to select the underlying system based on network assurance levels, (3) survey security functionalities of a network devoted to automotive applications and demonstrate how automotive applications, 5G network and physical infrastructure, cooperate for enhancing security of the end-to-end system, and (4) provide example security evaluation results at different assurance levels. The results show the necessity of providing different levels of network assurance during the certification process in order that the automotive customer will be able to select the best products and sub-systems that may demonstrate (assure) enough security to the complete system.
