A distributed architecture for autonomous navigation of robots
2002
The paper shows a distributed architecture for autonomous robot navigation. The architecture is based on three modules that are implemented on separate and interacting agents: the target recognizer, the obsta90cle evaluator and the planner. An adaptive genetic algorithm has been studied to identify mechanisms for reaching the target and for manipulating the 2-directions of the robot; the distributed architecture has been embedded in the DAISY (Distributed Architecture for Intelligent System). Experiments have been carried out using a LEGO intelligent brick.
Research Toward The Optical Equipment For An Autonomous Robot For TviV Environment
1989
The paper consists of three major parts: basic technical problems in very high power/megavolt environment, signal processing and mechanical equipment for this environment, construction of a sensor equipped robot for this environment. The first part contains mainly metrological confinements and reliability considerations for the optical, optoelectronic and electronic part of a system. The second part contains mechanics and robotics problems. The result of these two parts is a choice of a system to be realized.
Autonomous patrol and surveillance system using unmanned aerial vehicles
2015
Unmanned aerial vehicles (UAVs) are increasingly popular for civil applications due to their flight capabilities and mobility. This paper proposes an indoor autonomous patrol and surveillance system using unmanned aerial vehicles. The system consists of six components: (1) a low cost vision-based pose estimation of UAVs, (2) vision-based state estimation, (3) UAV patrol path planning, (4) UAV controller to desired waypoints, (5) manual joystick controller and (6) assignment of priority hierarchy to multiple control inputs of a robot. The components were integrated successfully and the designed system was experimented in an indoor setup. Results has shown that the proposed system is suitable…
Agent's actions as a classification criteria for the state space in a learning from rewards system
2008
We focus in this paper on the problem of learning an autonomous agent's policy when the state space is very large and the set of actions available is comparatively short. To this end, we use a non-parametric decision rule (concretely, a nearest-neighbour strategy) in order to cluster the state space by means of the action that leads to a successful situation. Using an exploration strategy to avoid greedy behaviour, the agent builds clusters of positively-classified states through trial and error learning. In this paper, we implement a 3D synthetic agent which plays an 'avoid the asteroid' game that suits our assumptions. Using as the state space a feature vector space extracted from a visua…
Recursos tecnológicos y actividades no presenciales para un mejor aprendizaje de la Estadística Actuarial
2010
En este artículo se describe el diseño y los resultados obtenidos con una estrategia didáctica innovadora para el aprendizaje de la Estadística Actuarial en la licenciatura de Ciencias Actuariales y Financieras de la Universidad de Málaga. Mediante un uso intensivo de actividades no presenciales y elementos tecnológicos que favorecen el aprendizaje en movilidad se pretende potenciar el aprendizaje autónomo, colaborativo y contextualizado. Para ello se han diseñado, entre otras, actividades de identificación y asimilación de competencias, un laboratorio virtual de supervivencia basado en un simulador gráfico interactivo y un microportal para dispositivos iPhone y iPod touch de Apple.
Ethics of Artificial Intelligence : Research Challenges and Potential Solutions
2020
Artificial Intelligence (AI) is a rapidly emerging paradigm with many applications in healthcare, industries, and smart cities. However, this rise of global interest in AI has fueled a renewed interest from the public sector and global policymakers. As AI networks (e.g., chatbots, automation systems, and helping agents) are paving their way as interactive household items, a critically important research issue is understanding the ethical impact of these autonomous agents. What is the explanation of the AI decision-making process? What are the legal, societal, and moral consequences of these decisions and actions? Should these AI systems be allowed to make decisions for human beings and to w…
Near zero energy islands in the Mediterranean: Supporting policies and local obstacles
2014
Abstract Based on a recent technical–economical analysis on the island of Pantelleria, a policy feasibility study for a complete upgrading of the energy system of this Mediterranean Island is carried out. Pantelleria, situated between Sicily and Africa, owns a large potential in terms of renewable energy resources, although there are some obstacles in turning it into a Near Zero Energy system. Starting from a deep energy system audit, the study proposes the project for a near zero energy island, through the efficient transformation of the different existing natural energy resources into electrical energy and heat: the solar, the wind-based and the geothermal systems. In this way, the island…
THE ECONOMIC VALUE OF THE EXTERNALITIES ASSOCIATED WITH CULTURAL GOODS
2001
This study examined the economic value of the externalities associated with cultural goods. The purpose of this study is to clarify the willingness to pay to maintain the Central Finland museum of the ones which had filled a 18 year of Jyväskylä inhabitants and of factors which affect a payment willingness. From dichotomous choice valuation (DC-method) data we have estimated the cumulative probability density function (cdf). From estimated cdf we can calculate welfare measures such as median of the estimated distribution of CV. The study found firstly that the surplus of the consumer is thus 1.17 MFIM measured on the basis of the median value. In the respondents' opinion the value of the C…
NATO Advanced Research Workshop on Explosives Detection
2019
As of 2017, there are an estimated 100 million abandoned land mines littered across 61 countries. Following the wars in Afghanistan, Libya, Syria, Yemen, and Ukraine, there has been a rise in casualties due to the triggering of previously-abandoned explosive devices. The above institutions combined specialties to develop a remotely-operable, multisensor, robotic device for the detection of land mines, UXO (1), and IEDs (2). The robotic detection device uses novel subsurface radar with imaging and target classification to differentiate between threatening landmines and innocuous clutter. The expected outcome of this research is the creation of a multi-sensor system on a semi-autonomous vehic…
Land invertebrates of Columbretes Islands : new species
2020
Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/2071-1050/13/4/1776 La fauna terrestre de invertebrados del archipiélago protegido de Columbretes es poco conocida. Además, los pocos estudios existentes se centran en su isla principal, Illa Grossa. Aquí presentamos el listado de espe-cies de invertebrados no registradas, hasta el momento, en el archipiélago, resultados obtenidos mediante una combinación de capturas con trampas de caída, avistamientos y recolecciones aleatorias realizadas tanto en Illa Grossa como en otros tres islotes de este archipiélago. Mediante el primer método se recolectaron un total de 14.830 especímenes entre 2008-2011. La mayor cantid…
