Metaconcrete (MC) is a class of engineered cementitious composites that integrates locally resonant inclusions to filter stress waves. While the dynamic benefits are well established, the effect of resonator content and geometry on static compressive resistance remains unclear. This study develops the first two-dimensional mesoscale finite-element...

Higher education has traditionally played the role of an overarching factor in economic growth and development. The implementation of the European Higher Education Area (EHEA) has already achieved improvements in many educational areas, but there remain, within the requirement to ensure academic excellence, cases where the quality criteria are not...

Metal additive manufacturing has emerged as a revolutionary technology for the fabrication of high-complexity components. However, this technique presents unique challenges related to the structural integrity and final strength of the parts produced due to inherent defects, such as porosity, cracks, and geometric deviations. These defects significa...

This chapter examines hot desks, a workspace strategy in which employees use available workstations instead of assigned desks. This has gained importance due to its potential for cost savings and flexibility. The chapter uses VOSviewer to analyze literature on hotdesking from 2010 to 2024. It highlights a peak in publications between 2016 and 2018,...

The evolving labor market, driven by technological advancements, significantly impacts society by shaping how businesses operate and how individuals work. Companies face the challenge of balancing digital transformation with sustainable practices, ensuring long-term economic and environmental stability. By embracing innovation, fostering resilience...

Gamification activities aim to improve student engagement and learning outcomes by integrating interactive and dynamic elements into classroom sessions. This paper presents the results obtained from an Educational Innovation Project implemented at the Universidad Politécnica de Madrid in Spain. The objectives are to evaluate the effectiveness of Wo...

Featured Application The strength and rigidity of the durable resin make it ideal for a wide range of applications, including prototyping and product development, automotive and aerospace components, medical devices, consumer goods, custom tooling, and educational models. Its strength and precision are precious in producing functional prototypes, n...

‘Drone’ is a widely used term to refer to any aerial vehicle being operated by using remote commands from a pilot or relying on software for autonomous flight. This aircraft type is more formally known as an Unmanned Aerial Vehicle (UAV), often forming an integral part of an Unmanned Aircraft System (UAS). Introducing such aerial devices in several...

El tiempo es el bien más preciado que tenemos las personas. Durante la juventud, es frecuente que el tiempo se relativice y, como consecuencia, se den usos del tiempo que no sean adecuados. En este libro abordamos el desafiante ámbito de la intervención socioeducativa en la autorregulación del tiempo, especialmente en el contexto del ocio, en la vi...

Financialization is a process within the global economy wherein financial markets have been gaining ground in recent years. And yet, whether it has a beneficial or detrimental impact is almost totally unstudied, notably in terms of market effects on the real estate sector. To probe more deeply into such a research issue, this study addresses how re...

Over the past 20 years, civil aviation has substantially reduced its environmental impact to augment sustainable transportation. In Spain, the domestic market has been habitually characterized by a few enterprises providing air transport services linked to scheduled flights on domestic corridors. Because of geographic diversity and the highly conce...

Mediterranean islands of the European Union (EU) have traditionally suffered from a lack of regularity in supplying public transportation due to the high seasonality of the demand for scheduled transport services. The insular fact forces people and goods to be carried either by sea or air, and therefore needs to actively stimulate interest in opera...

In economic literature, the relationship between entrepreneurship and economic growth has been widely discussed for some time now. In addition to the different theoretical approaches, a considerable amount of empirical works in recent decades have sought to verify the direct link between both variables by analyzing datasets from several distinct ge...

The promotion of efficient and sustainable means of transport has been a key issue of public debate across the European Union (EU). Particularly, transport needs in peripheral and remote areas have a great importance for EU transport policies in order to ensure the mobility of goods and persons in these regions, and thus to achieve greater territor...

The objective of this paper is to examine how the imposition of Public Service Obligations (PSO) on certain routes may affect the transportation sector, with a focus on aviation in the European Single Market. Thus, this research investigates how this form of public intervention can be useful to access adequeate transport system in remote and periph...

Airlines are open to and enjoy a high standard of regulations within the EU Internal aviation market. However, scheduled air services are at times restricted to the access of single markets due to the imposition of public service obligations. This situation is regarded as market failure so this chapter addresses some key aspects in which these impo...
