abstract = {The growing demand for sustainable and high-yield agriculture necessitates the deployment of autonomous, cost-effective, and resilient agricultural robot (agrirobot) fleets, particularly in labor-scarce rural areas with challenging working conditions. This paper presents the demo of the novel multi-agent architecture, Agri-RO5, for realistic simulation of dynamic agrirobot fleet coordination methods. The Agri-RO5 approach tackles the challenges in rural settings, including low connectivity and geographically dispersed farms. Our long-term goal is to develop digital twins to optimize real-world fleet performance. Agri-RO5 is implemented in Unity-3D, Robot Operating System (ROS), and an extension of the existing package Patrolling SIM to achieve high simulation fidelity representing real-world conditions. The integration allows the coordination solution into the controllers of actual physical robotic systems and ensures that simulations closely match real-world scenarios. Our system prioritizes a highly distributed architecture facilitated by incorporating SPADE3 and FIVE. SPADE3 provides a framework for developing and executing scalable multi-agent systems, while FIVE offers the creation of the environment and provides mechanisms to interact with the environment.},

abstract = {Technological advances, especially in the field of artificial intelligence, raise subjects related to the behaviour of autonomous systems. The ability to judge how far some behaviour is ethically correct is inherent to humans, and one of the great challenges is to replicate such ability in artificial systems. Engineering, aware that human values must be considered in the decision-making process, is currently focused on developing mechanisms to embed these values into autonomous systems. This article proposes a decision model that enables autonomous intelligent agents to select actions that are aligned with their value system. It considers not only the relevance that different values have for an agent, and how much an action promotes a certain value, but also models in a rigorous manner the interaction of different values within a value system. An instantiation of the model is put forward, based on Schwartz's basic values theory, non-additive fuzzy measures, and the discrete Choquet integral. Then the performance of the approach is illustrated by determining the value alignment of different decisions using the well-known iterated prisoner's dilemma.},

abstract = {Nowadays, Artificial Intelligence faces a significant challenge in implementing ethical behaviour in autonomous agents. The development of technologies that consider human values in the decision-making process of such agents is crucial. While this feature should be included in the agent's design objectives, the primary goal is to build value-aware agents that act appropriately in changing environments. This requires the creation of mechanisms that support the agent's own value system. This paper presents a model of an agent that makes decisions based on its value system and a value promotion scheme for available actions. The model uses a fuzzy measure to represent the value system, and aggregation operators to determine the action that best aligns with the agent's preferences. Schwartz's basic value theory and Choquet's discrete integral are used as an example of model implementation. Finally, the model is illustrated by determining the value alignment of different decisions in a simplified tax-paying context.},

We propose a scenario of practical legal and ethical reasoning based on values that protect against the infringement of labour laws, social conventions, and moral norms in personnel selection and onboarding. It is envisaged as a mix of ethical and legal reasoner. The ethical reasoner focuses on two central human values: trustworthiness and privacy. This paper introduces a Legal and ethical reasoner based on Answer Set Programming (ASP) that enables explainable and trustworthy outcomes in recruiting processes whilst safeguarding users' privacy and disclosing avoidance of protected attributes (gender, religion, pregnancy status, etc.).},

abstract = {The expansion of the Internet of Things is leading to the emergence of new IoT environments where devices not only act as sensors or actuators but also provide computing, storage and network resources. These resources are close to the local network and have a great potential to deploy IoT services, this is called fog computing. One of the challenges in this context is deciding the allocation of services to suitable computing nodes where they can run. In this paper, we propose a clustering-based method to allocate services to computing nodes along edge-cloud computing environments considering both functional and computational capacities. Additionally, the proposed framework is explained and an experimental example is used to test four clustering strategies. The results show that the proposed clustering approach is an efficient method for service allocation to computing nodes and depending on the selected strategy different workload distributions are obtained. Finally, we present some considerations about the proposed model.},

abstract = {In recent decades, society has a primary need for improving education systems. Predicting the performance of students has become a reference topic very analyzed by the research community. Currently, there are several cutting-edge technologies that make very easy to collect educational data in institutional systems due to the new information management systems where almost everything is digitalized. The analysis of this information offers unique opportunities that have a direct impact on students, instructors and academic institutions programs. Concretely, we propose a modular system to evaluate teaching performance by considering several primary factors related to students learning process. In this work, we present the first module, a statistical model that aims at obtaining the expected student's achievements in a particular course. We first analyzed students' performance primary factors on Higher Education Systems. To identify these factors, we have conducted a literature review. Then, we examine three different techniques to build the prediction model: Multiple Linear Regression (MLR), Support Vector Machine (SVM) and Artificial Neural Networks (ANN). To select the suitable technique, we carried out a variety of experiments by using a real dataset from University of Santa Elena (Ecuador). The achieved experiments revealed promising results.},

abstract = {In the last years, many novel applications have appeared that promote the provision of services or activities in a collaborative way. Examples of such proposals are collaborative transportation services (uber, glovo, amazon flex, etc.), crowdsourcing, exchange help services among citizens, and others. The intrinsic idea behind such systems is to take advantage of existing ``capacities'' for providing new services or incrementing the efficiency of daily tasks of people at a low cost. Also, many researchers have focused and are analysing novel ideas and approaches in this direction. The concept of Smart Cities is a clear representation of this hype and provides a playground for novel approaches where the aim is to provide a high level of services to citizens in an optimized and thus, more efficient way. As a result of this research effort, many proposals have been and are suggested that could be deployed in the real world. However, such proposals also bring up multiple non-technical issues that need to be tackled before they can be actually implemented in practice. In this sense, in this paper we analyse legal implications of a proposal for collaborative service provision. In particular, we analyse the legal issues related to a recent work on taxi assignments with compensation from the standpoint of the Spanish legislation. From this exercise, we extract a set of topics and requirements, which need to be addressed so as to pave the way for the potential real-world deployment of such a system in a future.},

In this paper, we focus on station-based bike sharing systems (BSS). This type of infrastructure (bikes and parking docks) is shared by many users. However, there are some inefficiencies in their management due to imbalanced situations in which some stations fail to provide the service (bike hires or returns) because they are empty or full. We tackle this problem by suggesting users to take (or return) bikes from stations with the goal of keeping the system as balanced as possible. We evaluate our proposal with Bike3S, a bike sharing system simulator developed for testing these types of strategies.},
