It addresses the challenges associated with optimizing additive manufacturing processes, particularly for polymer-based materials, and e...

With the publication of Organic Law 2/2023 on the University System (LOSU), the incorporation of Assistant Lecturers will present a challenge for universities. Since there is no prior accreditation for Assistant Lecturers by the faculty accreditation agencies, it is now necessary to conduct a preliminary evaluation of their performance halfway thro...

All organizations, regardless of their size and the sector to which they belong, must adapt to the era of digital transformation. The shipbuilding sector has also experienced this influence, but until now, the focus has been on digital technologies without analyzing how they affect the worker, assuming a positive assessment without objective eviden...

Since the entry into force of the regulations on the implementation of Low Emission Zones (LEZ) in Spain, many cities have taken action to comply with the legal requirements. This research will study the situation in Spain on 1st January, 2023. It will highlight the specific infrastructure and urban planning actions undertaken by the cities that ha...

The excellent tribological properties of copper are well known, which is why it is commonly used in components whose tribological characteristics have a high impact. Thanks to the characteristics of Additive Manufacturing it is possible to manufacture parts incorporating copper particles. However, the main mechanical studies are related to performa...

Currently, technical degrees continue to use classic methodologies based on the exposition by the teacher of well-structured content according to the descriptors established in the degree report, leaving little space for the teacher to establish his or her own structure. This generates stress for both students and teachers, seeing how their efforts...

Construction is a critical sector in the global economy, with significant contributions to society in areas such as employability, business growth, and prosperity. In a context in which this industry must face challenges of maintaining quality standards, integrating advanced technologies, adhering to stringent managerial restrictions, and complying...

With the increasing adoption of Additive Manufacturing in the industry, driven by its efficiency, productivity, and project profitability, materials have undergone significant evolution to enhance process performance and part properties. One of the processes employed to enhance these properties involves the incorporation of various types of reinfor...

A large vessel, such as a container ship or an oil tanker, requires painting processes that include not only application, but also cleaning, substrate preparation and corrosion treatment. Moreover, these processes take place during construction (both in the construction of blocks in the workshop and in the assembly at the dock) and also during the...

Petroleum product tanks are facilities used for the storage or handling of petroleum products. They are designed to avoid risks with respect to damage and breakage according to applicable regulations in their context, but for their correct operation they require periodic maintenance, among which cleaning procedures must be carried out. These activi...

Successful project management entails meeting the project objectives, completing the project scope, and achieving the set deliverables, fulfilling stakeholder requirements. Thus, the more complex and varied the expectations of the stakeholders, the greater the need for engaging them in the decision-making process. In this sense, the application of...

Determining the factors to be taken into account when designing a fixed-position plant layout is a difficult and important decision when dealing with the production of single products, such as in the case of fixed-position manu-facturing projects. In this type of project, the most important factors to take into account are the arrangement of materi...

Since the beginning of the second industrial revolution, the use of tanks for the storage of petroleum products ensured the permanent supply of equipment that depended on fossil fuel derived from petroleum, either for direct consumption or as an element for power generation. For correct operation, periodic cleaning of these confined spaces was requ...

One of the most important aspects in actual industry is sustainability. Due to stringent environmental regulations, companies have to increase their efforts to achieve the highest environmental profitability of their systems. Therefore, studies about the environmental impact of the entire life cycle of products are emerging, approach them from a ge...

The industry is using strategic materials of different nature in the form of stacked or hybrid structure. Combinations of carbon fiber-reinforced composites (CFRP) with light metallic alloys are widely used in recent years. Nevertheless, due to the different mechanical properties between the two materials, nonconventional machining technologies are...

The concept of smart factory marked by Industry 4.0, includes changes in business models involving a complete communication between the different companies involved in a manufacturing production process. Defining the project of the adaptation to Industry 4.0 of the manufacturing sector, the management of the same establishes methodologies that allo...

Projects characterized by high difficulty in terms of planning and administrative control, require the strategies facilitated by Manufacturing Project Systems (MPS). Among them is an adequate management of the Supply Chain used as a competitive strategy. It could be said that in the case of shipbuilding, the Supply Chain is much more complicated du...

The occupational risk prevention has been the subject of study for many years, but it could be said that in Spain, it is from the promulgation of laws in this regard when it becomes more important in view of the need to reduce the accident rate in all professions. Focusing on the engineering profession, the need arises to know if in their training...

Since its emergence, the industry has made great efforts to implement additive manufacturing processes in its production systems. However, to achieve this use, the precision of the parts must also be guaranteed. But it is not yet possible to achieve the characteristics required in certain industrial sectors like the aeronautical where highly rigoro...

The search for sustainability in the Supply Chain (SC) is one of the tasks that most concerns business leaders in all manufacturing sectors because of the importance that the Supply Chain has as a transversal tool and due to the leading role that it has been playing lately.
