Road Safety Audit for the US 61/Harrison Street and West Locust Street Intersection in Davenport-Scott County, Iowa, 2008

On the October 7 and 8, 2008, a road safety audit was conducted for the intersection of US 61/Harrison Street and West Locust Street in Davenport, Iowa. US 61/Harrison Street is a one-way street and a principal arterial route through Davenport, with three southbound lanes. Locust Street is a four-lane, two-way minor arterial running across the city from west to east. The last major improvement at this intersection was implemented approximately 20 years ago. The Iowa Department of Transportation requested a safety audit of this intersection in response to a high incidence of crashes at the location over the past several years, in view of the fact that no major improvements are anticipated for this intersection in the immediate future. The road safety audit team discussed current conditions at the intersection and reviewed the last seven years of crash data. The team also made daytime and nighttime field visits to the intersection to examine field conditions and observe traffic flow and crossing guard operations with younger pedestrians. After discussing key issues, the road safety audit team drew conclusions and suggested possible enforcement, engineering, public information, and educational strategies for mitigation.

Prevalence of alcohol-impaired drivers based on random breath tests in a roadside survey

Sobriety checkpoints are not usually randomly located by traffic authorities. As such, information provided by non-random alcohol tests cannot be used to infer the characteristics of the general driving population. In this paper a case study is presented in which the prevalence of alcohol-impaired driving is estimated for the general population of drivers. A stratified probabilistic sample was designed to represent vehicles circulating in non-urban areas of Catalonia (Spain), a region characterized by its complex transportation network and dense traffic around the metropolis of Barcelona. Random breath alcohol concentration tests were performed during spring 2012 on 7,596 drivers. The estimated prevalence of alcohol-impaired drivers was 1.29 PER CENT, which is roughly a third of the rate obtained in non-random tests. Higher rates were found on weekends (1.90 PER CENT on Saturdays, 4.29 PER CENT on Sundays) and especially at night. The rate is higher for men (1.45 PER CENT) than for women (0.64 PER CENT) and the percentage of positive outcomes shows an increasing pattern with age. In vehicles with two occupants, the proportion of alcohol-impaired drivers is estimated at 2.62 PER CENT, but when the driver was alone the rate drops to 0.84 PER CENT, which might reflect the socialization of drinking habits. The results are compared with outcomes in previous surveys, showing a decreasing trend in the prevalence of alcohol-impaired drivers over time.

Effectiveness of Pilotage

The objective of the pilotage effectiveness study was to come up with a process descrip-tion of the pilotage procedure, to design performance indicators based on this process description, to be used by Finnpilot, and to work out a preliminary plan for the imple-mentation of the indicators within the Finnpilot organisation. The theoretical aspects of pilotage as well as the guidelines and standards used were determined through a literature review. Based on the literature review, a process flow model with the following phases was created: the planning of pilotage, the start of pilo-tage, the act of pilotage, the end of pilotage and the closing of pilotage. The model based on the literature review was tested through interviews and observation of pilotage. At the same time an e-mail survey directed at foreign pilotage organisations, which included a questionnaire concerning their standards and management systems, operations procedures, measurement tools and their attitude to the passage planning, was conducted. The main issues in the observations and interviews were the passage plan and the bridge team co-operation. The phases of the pilotage process model emerged in both the pilotage activities and the interviews whereas bridge team co-operation was relatively marginal. Most of the pilotage organisations, who responded to the query, also use some standard-based management system. All organisations who answered the survey use some sort of a pilotage process model. According to the query, the main measuring tools for pilotage are statistical information concerning pilotage and the organisations, the customer feedback surveys, and financial results. Attitudes to-wards passage planning were mostly positive among the organisations. A workshop with pilotage experts was arranged where the process model constructed on the basis of the literature review was tuned to match practical pilotage. In the workshop it was determined that certain phases and the corresponding tasks, through which pilo-tage can be described as a process, were identifiable in all pilotage. The result of the workshop was a complemented process model, which separates incoming and outgoing traffic, as well as the fairway pilotage and harbour pilotage from each other. Addition-ally indicators divided according to the data gathering method were defined. Data con-cerning safety and traffic flow is gathered in the form of customer feedback. The pilot's own perceptions of the pilotage process are gathered through self-assessment. The measurement data which is connected to the phases of the pilotage process is generated e.g. by gathering statistics of the success of the pilot dispatches, the accuracy of the pi-lotage and the incidents that occurred during the pilotage, near misses, deviations and accidents. The measurement data is collected via the PilotWeb at the closing of the pilo-tage. A separate project and a project group with pilots also participating will be established for the deployment of the performance indicators. The phases of the project are: the definition phase, the implementation phase and the deployment phase. The purpose of the definition phase is to prepare questions for ship commanders concerning the cus-tomer feedback questionnaire and also to work out the self-assessment queries and the queries concerning the process indicators.

Helsingin seudun liikenteenhallinnan kärkihankkeiden päivitys 2011

Työn tavoitteena oli kokonaisnäkemyksen luominen Helsingin seudun liikenteenhallinnan tilasta ja kehitysnäkymistä sekä seuraavien tärkeimpien kehittämispolkujen tunnistaminen ja konkretisointi toimenpiteiksi. Työssä keskityttiin seuraaviin painopistealueisiin 1. Liityntäpysäköinnin informaation ja maksujärjestelmien kehittäminen 2. Liikenteenhallintakeskuksen toiminnan kehittäminen ja laajentaminen 3. Liikennejärjestelmän reaaliaikainen tilannekuva ja lyhyen aikavälin ennusteet 4. Pääkaupunkiseudun pääväylien ruuhkien ja häiriöiden hallinta 5. Joukkoliikenteen ajantasaisen matkustajainformaation kehittäminen. Työssä laadittiin katsaus kullakin painopistealueella jo tapahtuneeseen sekä käynnissä olevaan kehitystyöhön, kuvattiin esiin nousseita ongelmia ja laadittiin esitys vuoteen 2020 ulottuvasta toiminnallisesta tavoitetilasta sekä konkreettisista kehittämistoimista. Työssä järjestettiin myös tulevaisuustyöpaja, johon pyydettiin alustuksia valikoiduilta viranomaistahoilta, tutkijoilta ja palveluntuottajilta. Näiden keskustelujen kautta kirkastettiin seudun toimijoiden näkemystä älyliikenteen toimialan kehitysnäkymistä ja –tarpeista. Työn lopputuloksena syntyneeseen toimenpideohjelmaan kirjattiin yhteensä 30 hanketta. Näistä viisi hanketta valittiin työpajatyöskentelyn kautta varsinaisiksi kärkihankkeiksi, joiden toteutus on kriittistä liikkujien ja viranomaistyön palvelutason kannalta ja joka edellyttää usean toimijan yhteistyötä. Lisäksi tunnistettiin joukko seurattavia hankkeita. Valitut kärkihankkeet, käynnistämisen vastuutaho sekä tavoitteellinen käynnistysvuosi ovat seuraavat: 1. Liityntäpysäköinnin dynaamisen informaatiojärjestelmän pilotointi Hämeenlinnanväylän käytävässä Kehäradan asemilla (HSL 2012) 2. HSL:n alueen joukkoliikenteen häiriönhallinnan uudelleenorganisointi (HSL, Liikennevirasto 2012) 3. Seudullisen liikenteenhallintasuunnitelman laadinta verkollisen operoinnin kehittämiseksi häiriötilanteissa (ELY-keskus, Liikennevirasto 2013) 4. Reaaliaikaisen sujuvuustiedon tuottaminen ruuhkautuvalta pääkatu- ja alempiasteiselta maantieverkolta (Liikennevirasto, kunnat 2012) 5. Liikenteen vaihtuvan ohjauksen ja tiedottamisen hyödyntäminen pääväylien ruuhkautumisen ja häiriöiden hallinnassa. (ELY-keskus 2012) Kärkihankkeisiin ei liity sellaisia riippuvuuksia, että niitä ei voitaisi käynnistää ennen päätöksentekoa jostakin muusta investoinnista. Merkittävimmät riippuvuudet liittyvät LIJ2014-järjestelmän ajoneuvojen paikannuksen ja muiden työkalujen valmistumiseen. Johtoryhmän linjauksen mukaan kärkihankkeissa ja muissakin toimijoiden omissa hankkeissa syntyvien tietojärjestelmien rajapinnat avataan soveltuvasti kaupallisten toimijoiden käyttöön, jolloin syntyvien kaupallisten loppukäyttäjäpalveluiden kautta voidaan parantaa tietopalvelujen tavoittavuutta. Kärkihankkeiden valinta ja sisältö on rakennettu pitkälti sen lähtökohdan varaan, että liikenteen tietopalveluissa julkistoimijoiden roolina on pääasiassa lähtötietojen tuottaminen ja jakaminen varsinaisille palveluntuottajille. Vuoteen 2016 mennessä uusien rajapintojen kautta jaettavien tietojen määrä on nykyiseen verrattuna huomattavasti laajempi, ja odotukset uusien ja innovatiivisten palvelujen syntymiselle ovat korkeat. HLH-johtoryhmä nimeää jokaisen kärkihankkeen läpiviennistä vastaavan työryhmän, joiden työskentelyä ohjataan nykyisen kaltaisessa johtoryhmätyössä. Johtoryhmätyön organisointi on todettu toimivaksi, sillä ryhmä koostuu seudun 14 kunnan alueen keskeisistä julkisista toimijoista ja sen kautta on olemassa vahvat kytkennät sekä seudun liikennejärjestelmätyöhön (HLJ) että valtakunnalliseen älyliikenteen kehitystyöhön.

Yritysten kuljetusvirrat ja varastointi Pohjois-Euroopassa

Tämän työn tavoitteena on luoda kuva yritysten kuljetusvirroista ja varastointiratkaisuista Pohjois-Euroopassa. Päätutkimusmenetelmänä käytettiin verkkopohjaista kyselyä, jolla pyrittiin keräämään tietoa Suomen, Ruotsin ja Viron suurimpien yritysten logistisista ratkaisuista. Kyselytutkimus toteutettiin yhteistyössä Tallinnan teknillisen yliopiston sekä Jönköpingin yliopiston kanssa. Toimivat kuljetusjärjestelmät ovat nykyään elintärkeitä, sillä ne luovat edellytykset talouden kasvulle ja hyvinvoinnin lisääntymiselle. Myös akateemisessa tutkimuksessa on havaittu, että yritysten todellisista toiminnoista ja luvuista tulisi saada lisää tietoa. Tässä työssä kerättiin ja analysoitiin tietoa yritysten kuljetusyksiköistä, kuljetusmuodoista, kuljetuskustannuksista, kuljetusvirroista eri maiden välillä, varastointiratkaisuista sekä kabotaasikuljetusten ja rikkidirektiivin vaikutuksista. Kirjallisuus- ja kyselytutkimuksen perusteella puoliperävaunu ja kumipyöräkuljetukset ovat Pohjois-Euroopan suosituimmat kuljetuskeinot. Kyselytulosten mukaan varsinkaan suomalaiset yritykset eivät juuri käytä rautatiekuljetuksia, eikä rautatieyhteyttä pidetty tärkeänä varastojen sijainnista päätettäessä. Kuljetusvirrat Kiinan ja Euroopan välillä suuntautuvat Kiinasta Eurooppaan päin. Kiinasta tuleva kuljetusvirta tulee todennäköisesti pysymään vahvana myös tulevaisuudessa. Venäjän ja Euroopan väliset kuljetusvirrat suuntautuvat kyselytulosten perusteella Euroopasta Venäjälle päin. Pohjois-Euroopassa yrityksillä on käytössä pieniä ja keskikokoisia varastoja sekä suurempia jakelukeskuksia. Tulevaisuudessa varastot vaikuttaisivat keskittyvän hieman suuremmiksi yksiköiksi. Kyselytutkimuksen mukaan kabotaasikuljetukset ovat laskeneet ainakin joidenkin yritysten maantiekuljetusten kustannuksia. Rikkidirektiivin puolestaan odotetaan nostavan merikuljetusten hintoja sekä yritysten kuljetuskustannuksia huomattavasti.

La revue de la Chambre de commerce de Montréal et la modernisation de la métropole dans les années 1950 et 1960

Pendant les années 1950 et 1960, Montréal se modernise sur plusieurs aspects. L’influence de l’administration de la ville sur cette modernisation est bien connue. Toutefois, les perspectives des acteurs extérieurs sont souvent ignorées. Ce mémoire examine donc les opinions de la Chambre de commerce de Montréal sur la modernisation de la métropole québécoise lors de ces deux décennies. La source principale utilisée pour effectuer cette étude a été la revue hebdomadaire de la Chambre, Commerce-Montréal. Dans le premier chapitre, les opinions de la Chambre de commerce sur la gouvernance municipale sont examinées. Celles-ci montrent que la Chambre percevait l’assainissement des moeurs politiques et l’amélioration de l’efficacité administrative comme intrinsèques à la modernisation de Montréal. Le deuxième chapitre porte sur la circulation automobile et le transport en commun. La Chambre proposait des moyens d’accélérer le débit de la circulation qu’elle jugeait crucial pour la modernisation de la métropole. Le troisième chapitre traite du développement urbain. D’après la Chambre, la modernisation de Montréal exigeait le renouvellement du cadre bâti de la ville, tant résidentiel que commercial. L’étude de ces trois thèmes confirme que, pendant la période 1950-1970, la Chambre de commerce a contribué de manière significative aux débats concernant la modernisation de Montréal. Nous relevons aussi que l’organisme, malgré son désir de paraître apolitique, a été influencé par sa fonction de représentant de la communauté d’affaires francophone. L’importance accordée à la rentabilité de la modernisation, ainsi que la hiérarchisation sociale attribuée à certains sujets, confirment notamment les orientations conservatrices de l’organisme.

Incidencia de la problemática del narcotráfico en México, sobre la consolidación de la cooperación bilateral con Estados Unidos en la marco de la política antinarcóticos en el período 2000-2009.

La presente investigación pretende analizar la incidencia de la problemática del narcotráfico en México sobre la consolidación de la cooperación bilateral con Estados Unidos, en el lapso de tiempo entre 2000 y 2009. Para alcanzar dicho objetivo, en el primer capítulo se describen las principales dinámicas del narcotráfico en México, evidenciando las principales organizaciones criminales que se dan al interior del país y las actividades que promueven, así mismo, los principales flujos del tráfico de drogas hacia Estados Unidos. Posteriormente, en el segundo capítulo, se explican las consecuencias que esta problemática ha dejado en México y en Estados Unidos y a continuación, en el tercer y último capítulo, se lleva a cabo un análisis sobre la cooperación que se ha dado entre ambos países en pro de eliminar esta problemática. De igual manera, las fuentes que se emplean para el desarrollo de la presente investigación son de tipo secundarias, se emplean técnicas bibliográficas y documentos no académicos, páginas web, artículos de prensa, entre otros. En términos teóricos se toma como referencia la postura funcionalista expuesta por David Mitrany, y algunos elementos de la teoría de la Interdependencia compleja expuesta por Robert Keohane y Joseph Nye. De igual manera, se hace referencia a la reflexión de Buzan, quien hace énfasis en el concepto de seguridad regional y cómo ésta condiciona la agenda de los Estados.

Desenvolupament de mètodes de predicció de soroll i anàlisi de l'impacte acústic produït pel trànsit viari i el ferrocarril en la ciutat de Girona

La feina feta en aquest treball de tesis s'ha desenvolupat a partir de tres objectius vertebradors, que fonamentalment són: ·El primer dels objectius d'aquest treball de tesis és presentar un recull dels factors que intervenen en l'acústica urbanística: soroll produït pels diferents vehicles, fórmules de predicció de soroll, geometria dels edificis... , tot estudiant els seus efectes en la ciutat de Girona. ·Un altre objectiu ha estat desenvolupar uns mètodes numèrics propis, contrastats experimentalment i extrapolables a qualsevol entorn urbanístic, que permetin predir els valors de les pertorbacions acústiques produïdes pels diferents vehicles en diferents situacions, entre els que es destaquen: -Fórmula de predicció del soroll en un entorn urbà i la seva aplicació a Girona. -Càlcul de l'increment de soroll en un carrer provocat per les reflexions de les ones sonores en les façanes dels edificis. -Estudi del nivell de soroll en la boca de la cavitat d'un túnel produït pel pas del ferrocarril. -Determinació del soroll provocat pel pas d'un tren sobre un viaducte. -Mètode de distribució i planificació del trànsit urbà per disminuir l'impacte acústic sobre la zona. ·El darrer objectiu consisteix en fer una descripció analítica de les principals fonts de soroll que afecten a la ciutat: el trànsit viari i el ferrocarril. Per realitzar aquests objectius s'ha disposat d'un banc de dades amb més de 2.000 mesures sonores de Girona (nivells equivalents de 10 minuts de durada). La metodologia seguida i els principis en que es fonamenta es detallen a l'inici de cada apartat. La finalitat de tots aquests estudis, no és altre que millorar el confort acústic, i la qualitat de vida, de les ciutats. Gairebé tots els grans nuclis de població del planeta es veuen afectats per una gravíssima problemàtica mediambiental, doncs a l'anomenada contaminació acústica cal afegir uns alts índexs de pol·lució atmosfèrica (altes concentracions de biòxid de carboni, generació d'illes de calor...). Aquesta situació, generalitzada arreu del planeta, ha propiciat l'aparició de mesures dràstiques consistents fonamentalment en restringir l'accés dels vehicles motoritzats als nuclis i zones centrals de les àrees urbanes. Precisament aquesta opció s'ha proposat per les zones interiors de Girona on l'elevada densitat de les edificacions deixa un escàs marge per plantejar la construcció de noves rutes o vies alternatives. Cal esmentar que tots els càlculs i teories que es desenvolupen en aquest treball de tesis reflecteixen la realitat acústica actual provocada pels diferents mitjans de transport. Molt possiblement, en un futur no massa llunyà, els nivells de soroll (dB) enregistrats en situacions de tràfic similar seran força menors. Són molts els factors que poden contribuir a aquesta disminució de la intensitat de les emissions sonores: reducció del fregament mecànic, augment del coeficient aerodinàmic, nous materials pels pneumàtics i l'asfalt ... Sense cap mena de dubte, però, una millora transcendental, i no només pel que fa al confort acústic sinó per l'ecosistema en general, seria potenciar la construcció de motors elèctrics o d'hidrogen. Aquests últims per exemple, a diferència dels motors de combustió, funcionen mitjançant piles de combustible que converteixen, amb molta netedat, el gas hidrogen en electricitat i possibiliten l'existència de vehicles no contaminants propulsats per motors elèctrics menys sorollosos. Així, al haver-hi menys fregament entre les parts mòbils del motor (no hi ha pistons ni cilindres) el soroll generat es reduiria considerablement.

Kerb and urban increment of highly time-resolved trace elements in PM10, PM2.5 and PM1.0 winter aerosol in London during ClearfLo 2012

Ambient concentrations of trace elements with 2 h time resolution were measured in PM10–2.5, PM2.5–1.0 and PM1.0–0.3 size ranges at kerbside, urban background and rural sites in London during winter 2012. Samples were collected using rotating drum impactors (RDIs) and subsequently analysed with synchrotron radiation-induced X-ray fluorescence spectrometry (SR-XRF). Quantification of kerb and urban increments (defined as kerb-to-urban and urban-to-rural concentration ratios, respectively), and assessment of diurnal and weekly variability provided insight into sources governing urban air quality and the effects of urban micro-environments on human exposure. Traffic-related elements yielded the highest kerb increments, with values in the range of 10.4 to 16.6 for SW winds (3.3–6.9 for NE) observed for elements influenced by brake wear (e.g. Cu, Sb, Ba) and 5.7 to 8.2 for SW (2.6–3.0 for NE) for other traffic-related processes (e.g. Cr, Fe, Zn). Kerb increments for these elements were highest in the PM10–2.5 mass fraction, roughly twice that of the PM1.0–0.3 fraction. These elements also showed the highest urban increments (~ 3.0), although no difference was observed between brake wear and other traffic-related elements. All elements influenced by traffic exhibited higher concentrations during morning and evening rush hours, and on weekdays compared to weekends, with the strongest trends observed at the kerbside site, and additionally enhanced by winds coming directly from the road, consistent with street canyon effects. Elements related to mineral dust (e.g. Al, Si, Ca, Sr) showed significant influences from traffic-induced resuspension, as evidenced by moderate kerb (3.4–5.4 for SW, 1.7–2.3 for NE) and urban (~ 2) increments and increased concentrations during peak traffic flow. Elements related to regional transport showed no significant enhancement at kerb or urban sites, with the exception of PM10–2.5 sea salt (factor of up to 2), which may be influenced by traffic-induced resuspension of sea and/or road salt. Heavy-duty vehicles appeared to have a larger effect than passenger vehicles on the concentrations of all elements influenced by resuspension (including sea salt) and wearing processes. Trace element concentrations in London were influenced by both local and regional sources, with coarse and intermediate fractions dominated by traffic-induced resuspension and wearing processes and fine particles influenced by regional transport.

The dynamics of cargo driven by molecular motors in the context of asymmetric simple exclusion processes

We consider the dynamics of cargo driven by a collection of interacting molecular motors in the context of ail asymmetric simple exclusion process (ASEP). The model is formulated to account for (i) excluded-volume interactions, (ii) the observed asymmetry of the stochastic movement of individual motors and (iii) interactions between motors and cargo. Items (i) and (ii) form the basis of ASEP models and have already been considered to study the behavior of motor density profile [A. Parmeggiani. T. Franosch, E. Frey, Phase Coexistence in driven one-dimensional transport, Phys. Rev. Lett. 90 (2003) 086601-1-086601-4]. Item (iii) is new. It is introduced here as an attempt to describe explicitly the dependence of cargo movement on the dynamics of motors in this context. The steady-state Solutions Of the model indicate that the system undergoes a phase transition of condensation type as the motor density varies. We study the consequences of this transition to the behavior of the average cargo velocity. (C) 2009 Elsevier B.V. All rights reserved.

Road Sign Recognition based onInvariant Features using SupportVector Machine

Since last two decades researches have been working on developing systems that can assistsdrivers in the best way possible and make driving safe. Computer vision has played a crucialpart in design of these systems. With the introduction of vision techniques variousautonomous and robust real-time traffic automation systems have been designed such asTraffic monitoring, Traffic related parameter estimation and intelligent vehicles. Among theseautomatic detection and recognition of road signs has became an interesting research topic.The system can assist drivers about signs they don’t recognize before passing them.Aim of this research project is to present an Intelligent Road Sign Recognition System basedon state-of-the-art technique, the Support Vector Machine. The project is an extension to thework done at ITS research Platform at Dalarna University [25]. Focus of this research work ison the recognition of road signs under analysis. When classifying an image its location, sizeand orientation in the image plane are its irrelevant features and one way to get rid of thisambiguity is to extract those features which are invariant under the above mentionedtransformation. These invariant features are then used in Support Vector Machine forclassification. Support Vector Machine is a supervised learning machine that solves problemin higher dimension with the help of Kernel functions and is best know for classificationproblems.

Speed prediction for triggering vehicle activated signs

Accurate speed prediction is a crucial step in the development of a dynamic vehcile activated sign (VAS). A previous study showed that the optimal trigger speed of such signs will need to be pre-determined according to the nature of the site and to the traffic conditions. The objective of this paper is to find an accurate predictive model based on historical traffic speed data to derive the optimal trigger speed for such signs. Adaptive neuro fuzzy (ANFIS), classification and regression tree (CART) and random forest (RF) were developed to predict one step ahead speed during all times of the day. The developed models were evaluated and compared to the results obtained from artificial neural network (ANN), multiple linear regression (MLR) and naïve prediction using traffic speed data collected at four sites located in Sweden. The data were aggregated into two periods, a short term period (5-min) and a long term period (1-hour). The results of this study showed that using RF is a promising method for predicting mean speed in the two proposed periods.. It is concluded that in terms of performance and computational complexity, a simplistic input features to the predicitive model gave a marked increase in the response time of the model whilse still delivering a low prediction error.

Insuring cleaner oceans: the economics of oil pollution prevention

The current system of controlling oil spills involves a complex relationship of international, federal and state law, which has not proven to be very effective. The multiple layers of regulation often leave shipowners unsure of the laws facing them. Furthemore, nations have had difficulty enforcing these legal requirements. This thesis deals with the role marine insurance can play within the existing system of legislation to provide a strong preventative influence that is simple and cost-effective to enforce. In principle, insurance has two ways of enforcing higher safety standards and limiting the risk of an accident occurring. The first is through the use of insurance premiums that are based on the level of care taken by the insured. This means that a person engaging in riskier behavior faces a higher insurance premium, because their actions increase the probability of an accident occurring. The second method, available to the insurer, is collectively known as cancellation provisions or underwriting clauses. These are clauses written into an insurance contract that invalidates the agreement when certain conditions are not met by the insured The problem has been that obtaining information about the behavior of an insured party requires monitoring and that incurs a cost to the insurer. The application of these principles proves to be a more complicated matter. The modern marine insurance industry is a complicated system of multiple contracts, through different insurers, that covers the many facets of oil transportation. Their business practices have resulted in policy packages that cross the neat bounds of individual, specific insurance coverage. This paper shows that insurance can improve safety standards in three general areas -crew training, hull and equipment construction and maintenance, and routing schemes and exclusionary zones. With crew, hull and equipment, underwriting clauses can be used to ensure that minimum standards are met by the insured. Premiums can then be structured to reflect the additional care taken by the insured above and beyond these minimum standards. Routing schemes are traffic flow systems applied to congested waterways, such as the entrance to New York harbor. Using natural obstacles or manmade dividers, ships are separated into two lanes of opposing traffic, similar to a road. Exclusionary zones are marine areas designated off limits to tanker traffic either because of a sensitive ecosystem or because local knowledge is required of the region to ensure safe navigation. Underwriting clauses can be used to nullify an insurance contract when a tanker is not in compliance with established exclusionary zones or routing schemes.

Mapeamento acústico como ferramenta para predição de ruído urbano na área de influência do estádio Arena das Dunas, Natal/ RN

The Noise Pollution causes degradation in the quality of the environment and presents itself as one of the most common environmental problems in the big cities. An Urban environment present scenario and their complex acoustic study need to consider the contribution of various noise sources. Accordingly to computational models through mapping and prediction of acoustic scene become important, because they enable the realization of calculations, analyzes and reports, allowing the interpretation of satisfactory results. The study neighborhood is the neighborhood of Lagoa Nova, a central area of the city of Natal, which will undergo major changes in urban space due to urban mobility projects planned for the area around the stadium and the consequent changes of urban form and traffic. Thus, this study aims to evaluate the noise impact caused by road and morphological changes around the stadium Arena das Dunas in the neighborhood of Lagoa Nova, through on-site measurements and mapping using the computational model SoundPLAN year 2012 and the scenario evolution acoustic for the year 2017. For this analysis was the construction of the first acoustic mapping based on current diagnostic acoustic neighborhood, physical mapping, classified vehicle count and measurement of sound pressure level, and to build the prediction of noise were observed for the area study the modifications provided for traffic, urban form and mobility work. In this study, it is concluded that the sound pressure levels of the year in 2012 and 2017 extrapolate current legislation. For the prediction of noise were numerous changes in the acoustic scene, in which the works of urban mobility provided will improve traffic flow, thus reduce the sound pressure level where interventions are expected

3D relativistic hydrodynamic computations using lattice-QCD-inspired equations of state

In this communication, we report results of three-dimensional hydrodynamic computations, by using equations of state with a critical end Point as suggested by the lattice QCD. Some of the results are an increase of the multiplicity in the mid-rapidity region and a larger elliptic-flow parameter nu(2). We discuss also the effcts of the initial-condition fluctuations and the continuous emission.
