In this paper, an architecture for code-empowered optical CDMA (OCDMA) lightwave networks is presented. The architecture is based on reconfigurable optically transparent paths among users of the network to provide high-bandwidth optical connections on dema ...
In a network with capacity constraints congestion effects such as bottlenecks, spillbacks and gridlocks can be observed. These can be described with a queueing network model. The main challenge of such an approach lies in adequately capturing the between-q ...

There has been a significant growth in freight traffic over the last few decades in Europe. The Alps, located in the middle of North-South route, are particularly sensitive regarding this evolution because of their topographic and climatic characteristics. ...
The aim of this paper is to explore a new approach to obtain better traffic demand (Origin-Destination, OD matrices) in case of dense urban networks. To improve the global process of OD demand estimation, this paper is focussing on a new methodology to exe ...
The available capacity of motorway networks is degraded in presence of traffic congestion, leading to reduced throughput, increased pollution and higher accident risk. The traffic flow efficiency may be increased via suitable application of several control ...
Practical large-scale nonlinear control systems require an intensive and time-consuming effort for the fine-tuning of their control parameters in order to achieve a satisfactory performance. In most cases, the fine-tuning process may take years and is perf ...

Apart from the best-practice cases where public administration has been able to manage the transit service network and implement a strong regulation system, in the majority of Latin American cities public urban transport is supplied by a great number of qu ...
Designing a power-efficient interconnection architec- ture for MultiProcessor Systems-on-Chips (MPSoCs) satisfying the application performance constraints is a nontrivial task. In order to meet the tight time-to-market constraints and to effec- tively hand ...

Road safety has become a major concern and many strategies have been introduced to reduce road risk and mitigate severe consequences of unavoidable crashes. This paper presents an innovative methodology which aims at monitoring in real time and even antici ...
