In this study we introduce the regenerator location problem in flexible optical networks (RLP-FON). With a given traffic demand, RLP-FON tries to solve the regenerator placement, routing, bandwidth allocation and modulation selection problems jointly to satisfy data transfer demands with the minimum number of regenerators. We propose a novel branch and price algorithm for this challenging probl...

In this paper we compare the performance of opaque and translucent Optical Transport Networks (OTNs) taking into account different regenerator placement strategies. The translucent approach achieves noticeable results under static traffic in terms of saving of deployed resources. On the other hand in the dynamic scenario a translucent OTN suffers from fewer resources and may display high blocki...

Electrically heated regenerator storage is an energy- and cost-efficient solution for converting excess electricity storing it as high-temperature heat. We introduce a transient model to describe the thermodynamic behavior of this hybrid system with fewest number dimensionless parameters. These characteristic parameters are used derive key performance indicators assessment power-to-heat integra...

We propose a modification of a NALM-based 2R regenerator of phase-encoded signals which operates at considerably lower input powers than was studied earlier. Our modification consists of replacing the core-matched and lossless fiber coupler in the NALM by a coupler with a propagation constant mismatch and loss asymmetrically distributed between the two cores. The performance of the modified reg...

Stirling engine technologies have been applied to cogeneration systems mainly for residential applications. The performance of Stirling engines has been evaluated considering different operational conditions, which include the electrical and thermal production. Thermodynamic analysis of the Stirling engine’s performance has been conducted, using specially designed computing codes along with the...

Regenerator allocation consists on selecting which of the already installed regenerators in a translucent network may be used according to the dynamic traffic requests in order to maximize the quality of the optical signal while minimizing the opaqueness of the network. A recent study has shown that the performance of the regenerator allocation techniques strongly depends on the accuracy of the...

The regenerator plays an extremely important role in the Stirling circulation. A grid can be used for inverse machines at room temperature due to its low flow resistance. This paper proposes a hexagonal theoretically explore heat transfer properties cycle and establishes approximate analytical model analyze effect mechanism of working frequency, thermal diffusivity wall thickness on oscillation...

Magnetic cooling has been researched as an alternative near room-temperature refrigeration technology for the past two decades. However, one of its greatest limitations is lack materials which can be properly shaped optimal thermal-hydraulic performance while maintaining a substantial magnetocaloric effect at moderate fields (i.e., between 1 and 2 T) remaining mechanically (and chemically) stab...

Many coking plants have adopted the process of preheating flue gas to apply medium and low temperature selective catalytic reduction (SCR) denitrification technology, which increases NOx treatment cost, fuel consumption, generates secondary pollutants. Based on unique distribution characteristics coke oven regenerator, this work proposes a method for synergizing SCR inside regenerator remove NO...
