Fuzzy cooperative control of automated ground passenger vehicles
2007
In this paper a fuzzy motion control for cooperative passenger automated vehicles where there are not collisions between the closest ones is proposed. Based on the position of the target and on the initial position of each cooperative vehicle, a supervisory plans nonholonomic circular trajectories which are without intersections, while a fuzzy control strategy assures the asymptotical stability of the motion errors and the reaching of the target with low acceleration values along the planned trajectories. Based on the ISO 2631-1 standard, the saturation properties of the fuzzy maps guarantees low values of the longitudinal and lateral accelerations to assure the comfort of the passengers. T…
Osservazioni sulla viabilità antica nel comprensorio di Trapani
2020
This paper is aimed to analyze, in a preliminar way, the ancient road system in a selected area of the Northern Sicily, between Segesta and Trapani. The focus are the connections between main roads (the so-called via Valeria and the hypothetical pathways) and settlements, the morphological context and the most significant toponyms from the archaeological point of view. The research is carried out by the archaeological data, contemporary and historical cartography, and it is also focused on the secondary roads.
A Novel Technique for Monitoring the W-Beam Guardrails
2014
The paper addresses the problem of the measurement of guardrails’ deformations by means automatic analysis of optical images. The technique is founded on the analysis of high-resolution photos, obtained by means of 3D camera installed into a data vehicle. The novel methodology has been used to calculate the longitudinal safety barrier deformations for one W-beam guardrails installed along a rural road in Italy. The procedure has shown that digital image analysis can be used with the aim to monitoring guardrails and, therefore, for guarantee reasonable levels of protection against serious ran-off-road crashes.
The Location of an International Logistics Center in Poland as a Part of the One Belt One Road Initiative
2019
Wstęp: Inicjatywa Jednego Pasa i Drogi otwiera wiele możliwości rozwoju dla krajów Europy Środkowo-Wschodniej. Niektóre z nich są związane z możliwością budowy centrum logistycznego w tym rejonie. Dla Polski taka inwestycja przyniosłaby wiele korzyści, nie tylko z powodu rozwoju infrastruktury, ale także z tytułu przyśpieszenia wzrostu gospodarczego i tworzenia nowych miejsc pracy. W tym kontekście kluczowa staje się rola i lokalizacja takiego centrum logistycznego. Ze względu na nowość zagadnienia, zauważa się znaczny niedobór artykułów naukowych związanych z tą kwestią. Celem naukowym niniejszego artykułu jest wypełnienie istniejącej luki, określenie roli jaką powinno spełniać polskie cen…
The location of an international logistics center in Poland as a part of The One Belt One Road Initiative
2019
Background: The One Belt One Road initiative opens up many development opportunities for Central and Eastern European countries, some related to the possible construction of a logistics center in this area. For Poland, such an investment would also bring many benefits, not only due to infrastructure development, but also through acceleration of economic growth and job creation. In this context, the crucial issue becomes, what should be the role of an international logistics center and where should it be located. Due to the novelty of the subject, there is a shortcoming of scientific papers related to this issue. The scientific goal of the present paper is to fulfill the gap and to address …
Working to the conservation and good use of the Devonian palaeontological heritage in Floresta, Boyacá (Colombia): a review of teaching case studies …
2019
The Floresta Massif, located in the Eastern Cordillera of Colombia, has a diverse and precious natural heritage. It is one of the areas that contains an exceptional palaeontological heritage of the Middle Devonian not only of Colombia, but also of South America. This heritage is represented by fossil specimens of marine fauna and terrestrial flora (correlated with North America and Europe) of the Floresta and Cuche Formations, respectively. Since 2004, actions made by several academic and research institutions, community and local government have introduced schoolchildren, teenagers and University students to art and science, and have promoted the conservation of palaeontological heritage a…
Il pedone, dal viadotto alle greenway. Figure architettoniche del suolo per camminare in città, 1960-2015
2022
L’articolo traccia un quadro nel quale le fasi successive dell’architettura della città europea del Novecento si leggono attraverso il rapporto fra il pedone e la strada, e pone l’ipotesi che la condizione contemporanea di tale rapporto sia l’aggiornamento di un tema indicatore dell’evoluzione del ruolo della maglia viaria. Come ogni strada, la via pedonale è un’infrastruttura, in cui interagiscono l’idea di progresso, i modi di fabbricazione e consumo degli spazi urbani, nuovi orizzonti politici e di investimento economico, e che rinvia ad immaginari collettivi. A partire dall’inizio della pedonalizzazione, nei primi anni Sessanta, l’articolo discute in un’ottica comparativa e genealogica …
Effect of deicing salts on urban soils and health status of roadside trees in the Opole region.
2004
This article reports on a study whose aim was to evaluate the impact of snow removal salts on urban soil properties and the health of roadside trees. The evaluation was done by chemical analyses of soil samples and plant matter combined with toxicity testing, performed with a Protoxkit F, a protozoan microbiotest. Samples were collected at 45 locations on three main roads in the town of Opole (Poland). The roads differed in the snow removal technology and amount of chemical substances (mostly NaCI) used on them during the winter. The study showed that when soil was exposed to a high level of NaCI, it tended to be more alkaline and also exhibited increased content of Na + and Cl - . The toxi…
Sulla strada tra Palermo e Agrigento / On the road between Palermo and Agrigento
2015
Il collegamento tra Palermo e Agrigento è un percorso antico già esistente in epoca romana e documentato anche nei secoli successivi. La costruzione della rotabile ha inizio nel 1779 ad opera dei Borboni e verrà completata solo dopo l’Unificazione. La storia e le trasformazioni della strada consentono di delineare le relazioni dell’infrastruttura con il paesaggio e i centri abitati che punteggiano l‘attraversamento e, soprattutto, con la campagna di cui la strada è sempre stata compagna continua. The ground connection between Palermo and Agrigento is an ancient path already existing in Roman times and well documented even in the following centuries. The road was first built in 1779 during B…
Road design problems solved by affine arithmetic
2015
In this paper we propose the use of techniques based on range numbers for solving problems of road designing. We applied the Affine Arithmetic to verify the driver's visibility in a horizontal curve, providing very interesting results and confirming its usefulness even in the most complex analytical expressions. The preparation of charts such as those proposed in this paper also makes this method directly accessible to those not so familiar with this technique.
