Abstract:

Une grande majorité (85%) des ponts français a une portée inférieure à 50 m. Pour ce type d’ouvrage d’art, la charge de trafic peut être déterminante pour la conception et le recalcul. Or, en Europe, le fret routier a augmenté de 36.2% entre 1995 et 2010, et la croissance annuelle du volume transporté par la route a été évaluée à 1.7% entre 2005 et 2030. Il est donc essentiel de s’assurer que les infrastructures européennes sont en mesure de répondre à cette demande croissante en capacité structurelle des ouvrages. Pour les ouvrages neufs, les modèles de trafic dans les normes ou les législati

Abstract:

The advent of trends such as virtualization, cloud computing, IoT and BYOD has increased the traffic loads on modern enterprise and data-center networks. As the requirements on today’s networks increase, newer designs and solutions have sprout forth. Software-Defined Networking was developed to cater to the needs of modern networks and to improve traffic handling among other things. This study focuses on the ways SDN, specifically the OpenFlow standard, can be used to load-balance and increase the network throughput, in comparison to traditional methods such as Equal-Cost Load-Balancing.

Abstract:

The objective of this research was to investigate, develop and evaluate dynamic load-balancing strategies for parallel execution of microscopic road traffic simulations. Urban road traffic simulation presents irregular, and dynamically varying distributed computational load for a parallel processor system. The dynamic nature of road traffic simulation systems lead to uneven load distribution during simulation, even for a system that starts off with even load distributions. Load balancing is a potential way of achieving improved performance by reallocating work from highly loaded processors to

Abstract:

Wide area cellular mobile networks have rapidly evolved over the years. In the beginning achieving wide area coverage was a great achievement – enabling subscribers to call from wherever they were currently located and whenever they wanted. Additionally these systems supported mobility of subscribers, so that calls could continue even while a subscriber moved from one cell to another. Today mobility management is something everyone takes for granted. New functionality is continuously being developed for these networks. An important aspect of this evolution has been to enable new applications a

Monitoring and mining real-time network data streams are crucial operations for managing and operating data networks. The information that network operators desire to extract from the network traffic is of different size, granularity and accuracy depending on the measurement task (e.g., relevant data for capacity planning and intrusion detection are very different). To satisfy these different demands, a new class of monitoring systems is emerging to handle multiple and arbitrary monitoring applications.

Abstract:

Telecommunications companies (telcos) and Internet Service Providers (ISPs) monitor the traffic passing through their networks for the purposes of network evaluation and planning for future growth. Most monitoring techniques currently use a form of packet sampling. However, exhaustive monitoring is a preferable solution because it ensures accurate traffic characterization and also allows encoding operations, such as compression and encryption, to be performed. To overcome the very high computational cost of exhaustive monitoring and encoding of data, this thesis suggests exploiting p

Abstract:

In this research, the performance of buried flexible pipe subjected to traffic load was investigated. First, a numerical parametric study was performed to study the influence of eight factors on pipe-soil behaviour under surface load using ABAQUS. Then, the impact of surface pressure, burial depth, number of cycles and cement stabilization on model response was investigated using laboratory experiments and numerical simulations. Equations were developed using Linear Regression Model and Artificial Neural Network using MATLAB.

Abstract:

O fenômeno do congestionamento, decorrente do rápido aumento da demanda por todos os meios de transporte só tende a se agravar, já que sistemas de transporte (vistos como um todo) têm um grande impacto na economia mundial. No caso do transporte veicular em particular, é notório que a demanda por mobilidade é uma das características da nossa sociedade. O impacto direto e indireto dos congestionamentos em áreas urbanas e interurbanas é imenso, e precisam ser avaliados adequadamente para que seus efeitos sejam pelo menos minorados.

Abstract:

This research is part of a major project with a stimulus that rose from the need to manage a large number of ageing bridges in low traffic volume roads (LTVR) in Australia. The project investigated, designed and consequently constructed, involved replacing an ageing super-structure of a 10m span bridge with a disused Flat-bed Rail Wagon (FRW). This research, therefore, is developed on the premises that the FRW can be adopted as the main structural system for the bridges in LTVR network. The main focus of this research is to present two alternate deck wearing systems (DWS) as part of the design

Abstract:

This diploma thesis deals with a proposal and a comparison of several options of transportation planning in the shopping area in the urban area of the town of Modřice, which is enlarging due to the building-up of new commercial centres. The first part of the thesis consists of a treatise on the field of traffic engineering, road-traffic telematics and ITS. The core of the work is formed by a detailed analysis of the current state and calibration of the transport simulation system AIMSUN. The following part shows three different ways of transportation in the given area and all of them include a

Abstract:

This study was conducted at the Swedish Defense research agency as an attempt to understand affordances and limitations in visualizing altitude information for fighter controllers. The fighter controllers are subject to large quantities of numerical information from multiple sources simultaneously. Their duties are highly stressful and require large mental workload and situational awareness. Today, a large portion of information is represented visually, except for altitude. The altitude of a jet is represented only numerically on the screen, next to the icon representing an airplane. This thes

A caracterização das cargas do tráfego é de grande importância para o dimensionamento de pavimentos, bem como para a quantificação do desempenho para fins de gerência de pavimentos. A utilização de abordagens empíricas para determinar os efeitos das cargas do tráfego nas estruturas de pavimentos, datadas dos anos 1960, apresentam sérias limitações, pois seus resultados são válidos somente para os mesmos, ou muito similares, fatores intervenientes que prevaleciam quando do seu desenvolvimento.

Abstract:

Inter-cell interference coordination in 3GPP Long Term Evolution system received much attention in recent years. However, most of the studies are based on ideal system with regular hexagon-shaped cell. The indoor environment has special characteristics that the building shape and BS locations are irregular; the traffic load has great variation compared to urban and rural area. So, conventional ICIC scheme may not be used in indoor situation directly. In this thesis, ICIC scheme is employed for indoor environment. Based on different quality of backhaul, static and dynamic schemes will be propos
