URBAN FLOWS SIMULATOR BASED ON COMPLEX SYSTEM OF QUEUES: PROCEDURES FOR SIMULATOR GENERATION
No full textIn a previous work [Pasini L and Feliziani S 2013 TASK Quart. 17 (3) 155], we have defined an object library that allows the building of architectural models of urban traffic systems. In this work we illustrate the procedures that enable us to produce a system simulator starting from the architectural model of an urban vehicular traffic system
VEHICULAR TRAFFIC SIMULATIONS: USE OF A GAMES ENGINE FOR VIDEO RENDERING AND VERIFICATION OF AN ARCHITECTURE MODEL BASED ON QUEUING SYSTEMS
No full textIn a previous work [Pasini L and Sabatini S 2016 TASK Quart. 20 (1) 9], we described a technique that allows a specific system of urban traffic to be associated to a description file system, called Model.dat. This file contains a list of data objects that are defined in the library [Pasini L and Feliziani S 2013 TASK Quart. 17 (3) 155] and that form the architecture model of a vehicular traffic system. This model turns out to be a network of queuing systems. In this work, we illustrate how we adapted the old procedure to study a new urban traffic system. Moreover, through a new tracking procedure, we illustrate how we developed a graphic simulation able to reinterpret the data from the simulation of the queuing networks model, in order to make it easier to check the effectiveness of the simulator and to have a graphical way to analyze the data

Vecchie e nuove epidemie. Mostra, Palazzo storico dell'Università, 28 ottobre - 4 dicembre 2010
No full textObiettivo della mostra, alla quale in chiusura nel giorno 4 dicembre 2010 è stato collegato un convegno di approfondimento, ha illustrato come le epidemie abbiano attraversato per secoli il cammino dell'uomo seminando lutti, sofferenze e sconvolgimenti demografici. Peste, sifilide, vaiolo, tubercolosi, tifo petecchiale e colera hanno provocato milioni di vittime e segnato il destino di individui, famiglie, comunità e nazioni. Anche nel nostro mondo civilizzato e tecnologico le epidemie rappresentano uno dei principali rischi di sanità pubblica. Alle tradizionali malattie infettive si sono aggiunte negli ultimi decenni numerose nuove malattie trasmissibili, soprattutto di natura virale, chiamate malattie infettive emergenti. L'AIDS resta la più importante di questo gruppo ma molte altre hanno minacciato la salute globale.Tra queste la SARS, l'infezione da virus Ebola, l'influenza aviaria, la pandemia influenzale da virus A/H1N1. La globalizzazione economica, gli oltre ottocento milioni di arrivi internazionali che si verificano ogni anno, la rapidità dei mezzi di trasporto ed il commercio internazionale di alimenti e di animali, rendono molto alto il rischio che una qualsiasi epidemia locale si trasformi in poche settimane in una epidemia di dimensione internazionale.Per fronteggiare le nuove sfide, per saper diagnosticare rapidamente malattie infettive vecchie e nuove a carattere epidemico, il medico deve aggiornare le proprie conoscenze in materia. Anche il convegno "vecchie e nuove epidemie", che è stato programmato a Modena sabato 4 dicembre 2010 presso l'Aula Magna Storica, ha voluto rappresentare un contributo in questo senso

Distribution and habitat: — Trichocline cisplatina was collected in southern Brazil, in the State of Rio Grande do Sul (Fig. 3) in the physiographic regions locally known as Encosta do Sudeste, Litoral and Serra do Sudeste. It is also known from southeastern Uruguay, municipality of La Pedrera, Rocha Province. The region where the species occurs belongs to the Pampean Biogeographical Province, which is restricted to Rio Grande do Sul State in Brazil (Cabrera & Willink 1973). The floristic physiognomies in which this species in found vary from grasslands and shrublands to pioneer vegetation along coastal plains in the southeastern part of the State, at an elevation range between 0 to 400 m a.s.l. According to field observations and notes associated with herbarium specimens, T. cisplatina grows on grasslands and shrublands with rocky or sandy soils and dunes. Phenology: —Flowering and fruiting specimens have been collected from September to May. Conservation Status: —According to the IUCN Red list (IUCN 2001) the species is considered to be vulnerable (VU, subcriteria A3, A1’s (c) and (e)–a decline of quality of habitat and the effect of introduced taxa), due to the introduction of Pinus spp. and the presence of Ulex europaeus L. (1753: 741) in the area of occurrence of the species. Etymology: —The specific epithet refers to the species occurrence in the former Cisplatina Province, which once belonged to Brazil and today is within Uruguayan territory. In Latin, “cis” means on this side, and “Platina” refers to Río de la Plata or Riverplate. Additional specimens examined (paratypes): — BRAZIL.

L . Cabrera 32311 (SI, LP); Punta de las Rocas, 9 December 2001, E . Figueredo s.n. (MVJB 21080). This new species was first collected by Sacco (Sacco 1199) in 1959 and identified by B. Rambo in the same year as T. incana Cass. (1826: 216). In the last fifty years the species has been identified by taxonomists as T. catharinensis, T. incana, T. macrocephala Less. (1830: 288), T. sinuata (Don) Cabrera (1953: 531) or as Trichocline sp. In fact, the renowned botanist A.L. Cabrera, who described the most morphologically similar species, T. catharinensis, in 1973, collected this new species, and identified it as Trichocline sp. According to Zardini (1975) T. catharinensis is restricted to southern Brazil, endemic to high elevation areas between 750 and 1500 m (Santa Catarina and Rio Grande do Sul States). However in the examined material of T. catharinensis, Zardini cites some herbarium specimens (E. Pereira 8445, Pereira & Pabst 7720, Pereira 6782 & Pabst 6608, Burkart 25200) that occur in the southern region of Rio Grande do Sul state, in lower elevations areas between 0 to 400 m. In the present work these materials indicated by Zardini were analyzed and identified as T. cisplatina. Trichocline cisplatina is similar to T. catharinensis in the morphology of the innermost phyllaries. These are lanceolate, brownish red and 1-2-seriate in both species. According to Cabrera & Klein (1973), there are two varieties of T. catharinensis: T. catharinensis var. catharinensis and T. catharinensis var. discolor Cabrera (1973: 48). The new species is most similar to T. catharinenses var. discolor, with which it shares pinatifid leaves and whitish ovary trichomes. Trichocline cisplatina can be distinguished from both varieties of T. catharinensis by its procumbent scape, deeply pinatifid leaves with 4-10 pairs of rounded lobes, yelloworange ray floret corollas, broader capitula and phyllaries and ovaries with 2-seriate trichomes that are inflated at the apex and densely distributed. Furthermore, these two species have a disjunct distribution in southern Brazil. Trichocline catharinensis occurs in grasslands and shrublands of high elevation areas between 750 to 1500 m and T. cisplatina is endemic to low elevation areas in the coastal region of southern Rio Grande do Sul State and southeastern Uruguay, occurring on grasslands and shrublands with rocky or sandy soils and dunes.Published as part of Pasini, Eduardo & Ritter, Mara Rejane, 2012, Trichocline cisplatina (Asteraceae, Mutisieae), a new species from southern Brazil and Uruguay, pp. 19-25 in Phytotaxa 42 on pages 20-24, DOI: 10.11646/phytotaxa.42.1.3, http://zenodo.org/record/489480

No full textZosteriform idiopathic atrophoderma of Pasini and Pierini
No full textIdiopathic atrophoderma of Pasini and Pierini (IAPP) is a rare disease of unknown etiology characterized by well-defined atrophic plaques with a “cliff-drop” border that show no signs of inflammation, sclerosis, and induration. The trunk is most commonly affected site. It usually affects the body in a bilaterally symmetrical distribution, although asymmetric involvement has also been reported. Very few cases occurring in a zosteriform distribution have been reported. In this article, the author reports a rare case of IAPP in an 18-year-old male where the lesions are distributed in a zosteriform distribution on the trunk

(G-network) and Energy Packet Network (EPN) models. He presents a simplified
model of an EPN that can be mathematically expressed by a system of equations,
whose nodes include distributed energy generators, energy storage and energy
consumers. The author investigates the maximal amount of work done per unit of
time in the EPN. He formulates this as an optimization problem and analyzes its
optimal solutions analytically
