Evaluation of Bond Retainage in Portland Cement Concrete Overlays Using Infrared Thermography and Ground Penetrating Radar, HR-537, Final Report, 1989

When concrete deterioration begins to occur in highway pavement, repairs become necessary to assure the rider safety, extend its useful life and restore its riding qualities. One rehabilitation technique used to restore the pavement to acceptable highway standards is to apply a thin portland cement concrete (PCC) overlay to the existing pavement. First, any necessary repairs are made to the existing pavement, the surface is then prepared, and the PCC overlay is applied. Brice Petrides-Donohue, Inc. (Donohue) was retained by the Iowa Department of Transportation (IDOT) to evaluate the present condition with respect to debonding of the PCC overlay at fifteen sites on Interstate 80 and State Highway 141 throughout the State of Iowa. This was accomplished by conducting an infrared thermographic and ground penetrating radar survey of these sites which were selected by the Iowa Department of Transportation. The fifteen selected sites were all two lanes wide and one-tenth of a mile long, for a total of three lane miles or 190,080 square feet. The selected sites are as follows: On Interstate 80 Eastbound, from milepost 35.25 to 35.35, milepost 36.00 to 36.10, milepost 37.00 to 37.10, milepost 38.00 to 38.10 and milepost 39.00 to 39.10, on State Highway 141 from milepost 134.00 to 134.10, milepost 134.90 to milepost 135.00, milepost 135.90 to 136.00, milepost 137.00 to 137.10 and milepost 138.00 to 138.10, and on Interstate 80 Westbound from milepost 184.00 to 184.10, milepost 185.00 to 185.10, milepost 186.00 to 186.10, milepost 187.00 to 187.10, and from milepost 188.00 to 188.10.

Les stratégies visant à améliorer l’acceptabilité des voies de contournement dans les petites municipalités du Québec : le cas de quatre municipalités le long de la route 117 dans la région des Laurentides

Cette recherche explore les différentes stratégies mises en place afin de minimiser les impacts négatifs encourus à la suite de la mise en service d'une voie de contournement pour les petites municipalités du Québec. Les stratégies identifiées ont été relevées dans la littérature, dans la documentation municipale ainsi que dans des études de cas, soit par des relevés terrains et des entretiens sur le territoire de quatre (4) municipalités. Les stratégies de planification mises sur pied visent essentiellement la configuration des entrées de villes, la signalisation ainsi que les programmes de revitalisation des noyaux urbains. Il ressort de l'analyse que la bonne acceptation sociale des voies de contournement est liée à la présence de concertation entre les différentes parties prenantes d'un projet tout au long de celui-ci. De plus, le temps écoulé entre les premiers balbutiements du projet et la mise en service d'une voie de contournement doit être d'une durée acceptable afin que des stratégies planifiées concordent avec le contexte économique et culturel dans lequel s'insèrera le projet. La recherche dresse ainsi le portrait des stratégies planifiées pour les municipalités situées le long de la route nationale 117 et ayant des voies de contournement. Plus spécifiquement, l'étude de cas porte sur les municipalités de Mont-Tremblant (secteur de Saint-Jovite), La Conception, Labelle et Rivière-Rouge dans la région des Laurentides.

System Design: UML Activity and Sequence Diagrams

In this session we look at how to model flow of control and interactions between components using UML Activity and Sequence Diagrams. This is an introductory session and so for Activity Diagrams we only cover branching, forks and joins and swim lanes, and for Sequence we cover lifelines, messages and returns, and alt, par and opt frames.

Empires, Religion & Trade

The Indian Ocean became the meeting point of two emerging empires in the early 16th century: the Mughal and the Portuguese empires, both different in their nature and objectives. While the Mughals were the dominant land power in the Indian subcontinent, the Portuguese dominated the coastal waters and the sea lanes They influenced each other’s fortunes, and of the region as a whole.

Multi-vehicle planning using RRT-connect

The problem of planning multiple vehicles deals with the design of an effective algorithm that can cause multiple autonomous vehicles on the road to communicate and generate a collaborative optimal travel plan. Our modelling of the problem considers vehicles to vary greatly in terms of both size and speed, which makes it suboptimal to have a faster vehicle follow a slower vehicle or for vehicles to drive with predefined speed lanes. It is essential to have a fast planning algorithm whilst still being probabilistically complete. The Rapidly Exploring Random Trees (RRT) algorithm developed and reported on here uses a problem specific coordination axis, a local optimization algorithm, priority based coordination, and a module for deciding travel speeds. Vehicles are assumed to remain in their current relative position laterally on the road unless otherwise instructed. Experimental results presented here show regular driving behaviours, namely vehicle following, overtaking, and complex obstacle avoidance. The ability to showcase complex behaviours in the absence of speed lanes is characteristic of the solution developed.

Multi-level planning for semi-autonomous vehicles in traffic scenarios based on separation maximization

The planning of semi-autonomous vehicles in traffic scenarios is a relatively new problem that contributes towards the goal of making road travel by vehicles free of human drivers. An algorithm needs to ensure optimal real time planning of multiple vehicles (moving in either direction along a road), in the presence of a complex obstacle network. Unlike other approaches, here we assume that speed lanes are not present and that different lanes do not need to be maintained for inbound and outbound traffic. Our basic hypothesis is to carry forward the planning task to ensure that a sufficient distance is maintained by each vehicle from all other vehicles, obstacles and road boundaries. We present here a 4-layer planning algorithm that consists of road selection (for selecting the individual roads of traversal to reach the goal), pathway selection (a strategy to avoid and/or overtake obstacles, road diversions and other blockages), pathway distribution (to select the position of a vehicle at every instance of time in a pathway), and trajectory generation (for generating a curve, smooth enough, to allow for the maximum possible speed). Cooperation between vehicles is handled separately at the different levels, the aim being to maximize the separation between vehicles. Simulated results exhibit behaviours of smooth, efficient and safe driving of vehicles in multiple scenarios; along with typical vehicle behaviours including following and overtaking.

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.

Parcelamento do solo, a necessidade de uniformizar alguns padrões de projetos das vias urbanas

Este trabalho faz uma análise da legislação sobre o parcelamento do solo nas diferentes instâncias de Governo. São analisadas as diversidades e contradições das leis municipais de parcelamento do solo de onze prefeituras estrategicamente distribuídas no Estado. A análise foca em particular o tratamento da hierarquia viária; as dimensões dos gabaritos viários; as rampas empregadas; o comprimento máximo dos quarteirões nos loteamentos residenciais em função da testada mínima dos lotes e a concordância vertical nas interseções. São analisados também os requisitos técnicos de projeto geométrico de vias urbanas estabelecidas por Órgãos federais e estaduais. A revisão bibliográfica aborda questões fundamentais na urbanização tais como os pedestres, as interseções e a capacidade das vias urbanas, com o propósito de sustentar a proposição de alterações nos requisitos técnicos preconizados pelas legislações sobre o parcelamento do solo urbano. Suprindo lacuna constatada na legislação municipal sobre o parcelamento do solo e, fundamentado em simulação gráfica com veículo de transporte coletivo urbano, o trabalho apresenta tabela com sugestões para o tratamento de curvas verticais nas interseções das vias urbanas nos loteamentos. Com as informações obtidas da análise da legislação, na pesquisa bibliográfica e dos requisitos técnicos constantes nas normas conhecidas, propõe-se dimensões para vias urbanas, comprimento ideal para quarteirões residenciais, valores de taxas de declividade urbana e formas de executar-se a concordância destas rampas nas interseções. Com os valores planimétricos sugeridos fez-se um parcelamento em gleba fictícia e comparou-se os resultados com outros loteamentos projetados na mesma gleba utilizando-se as prescrições das leis municipais estudadas.

Transport modelling: macro and micro simulation for the studied case of Funchal

The work done in this thesis attempts to demonstrate the importance of using models that can predict and represent the mobility of our society. To answer the proposed challenges two models were examined, the first corresponds to macro simulation with the intention of finding a solution to the frequency of the bus company Horários do Funchal, responsible for transport in the city of Funchal, and some surrounding areas. Where based on a simplified model of the city it was possible to increase the frequency of journeys getting an overall reduction in costs. The second model concerns the micro simulation of Avenida do Mar, where currently is being built a new roundabout (Praça da Autonomia), which connects with this avenue. Therefore it was proposed to study the impact on local traffic, and the implementation of new traffic lights for this purpose. Four possible situations in which was seen the possibility of increasing the number of lanes on the roundabout or the insertion of a bus lane were created. The results showed that having a roundabout with three lanes running is the best option because the waiting queues are minimal, and at environmental level this model will project fewer pollutants. Thus, this thesis presents two possible methods of urban planning. Transport modelling is an area that is under constant development, the global goal is to encourage more and more the use of these models, and as such it is important to have more people to devote themselves to studying new ways of addressing current problems, so that we can have more accurate models and increasing their credibility.

A cena contemporânea aos pedaços : observação de um experimento pedagógico

We try to relate this research with other logic, to discover a path of practical approach to approach a creation composed of fragments and a search of parameters for the aesthetics of appropriation. Accordingly, we find relationship with the theater composed of fragments, where different styles are appropriate theatrical and representational styles are merged with each other. Discusses in the first chapter on the theater composed of fragments, and stroll through lanes of the strategies of some directors in the ways of the contemporary scene. In the second chapter we seek procedures and concepts of atmosphere Mikhail Tchekhov (TCHEKHOV, 1996), and the transition from point-to-point by Scott McCloud (2005). In the third part we describe the observation of the experiment conducted by the students of the Bachelor's Degree in Regional Theatre at the University of Cariri in Juazeiro, Ceará, in 2010. Using the methodology of "pesquisa-ação", observing that the scenic writing end of the experiment, called "Toque Me", and the presentation in the cities of Crato and Barbalha, in August 2010, contained elements of the strategies from theater fragmentary scenes and conceptual contents of contemporary theater

O aspecto polifônico d os Lusíadas

A study about the polyphonic aspect of The Lusiads. An epic poem in Portuguese Language written by Luís de Camões, that narrates the adventure of the journey of Vasco da Gama in the discoverer of new shipping lanes for the Índias. Secondarily, tells the historics battles engaged during the process of foundation and consolidation of the Portuguese Empire. The object of the study are the diverse speeches that compose the poem s narration, aiming at to the possible aesthetic relation of the epic poetry of Camões with the novelistic prose developed in the modernity, starting with D. Quijote and consacrating it at polyphonic novels written by Dostoiévski. The sdudy focuses the singularity of Camões lies in the elaboration of a narrative structurally epic, but at the same time contains several deviating speeches. Such speeches emphasize the multiple planes and multiple voices (characteristics of novelistic prose) without, however, prejudice the interlinking logical-formal epos, resulting in the monological finish conventional of the epic gender. This feature characterizes The Lusiads as monological literary work, but also shows dialogism and plurilinguism, essentials to the polyphonic phenomenon. Another prominent aspect of the poetry of Camões is the relative procedure to the expressiveness of the characters. They are, in the majority, rhetorical creations, which assume, in the speech, human or myhtological characteristics. Stratagem that permits to the poet to emit a multiple faces of vision of the facts told. The analysis of the speeches supports-itself entirely in the polyphonic theory of Mikhail Bakhtin, shall be cited, accessory, viewpoints of others theoretical, as long if it is judged compatible with the theory adopted

Cartografia de uma intervenção comunitária para prevenção de DST/HIV/AIDS

Community-based interventions have been presented as a proposal of operationalization of the concept of vulnerability to STD/Aids prevention. This study aimed to analyze the Community intervention developed through the project Strengthening of Community action networks for STD/Aids prevention: know and intervenein, at Mãe Luiza neighborhood, in the city of Natal, State of Rio Grande do Norte, Brazil. The study was conducted in the same location where intervention occurs and took as time reference the first 30 months of construction and deployment process, from April 2010 until December 2012. This is research with qualitative approach, participatory character, developed from the immersion of the researcher in the field, being this community intervention itself. In this perspective, the study approximates to the Cartographic method in which the researcher-researched is engendered in the acts and effects research. The data-generating sources were the memories of the researcher from the field notes, written narratives of subjects involved in the intervention and documents pertaining to the project. In the methodological path of cartography, the image of the rhizome by Deleuze and Guattari (1995) has accompanied the immersion in the field given the nature of research-intervention which approach to the concept of object-Rhizome. The presentation of results was composed for the attempted rhizomatic and a hypertext representation, based on the descriptive narrative taken from the documentary analysis and the multi-faceted narratives with the voices, the looks and the affections narrated by the subject involved, respectively. On the path taken, three lanes were drawn as synthesis of learning produced by experience-that can contribute to understanding the process under study, in his singular character, and reflections on other experiences of community intervention: track 1- Community intervention as active-reflective space and a cause; track 2 Inclusion as power and challenge of community involvement; track 3 Sustainability as A challenge of Community intervention. The study indicates that community intervention is presented as a potential producer of health as also produces practical and creative skills, subjects and inventive in the daily life of the community with a view to reinventing knowledge and practices for the prevention of STD/HIV/Aids
