We report on the midinfrared emission from electroluminescent devices with quantum cascade active regions based on InGaAs/InP heterostructures.

We report on a novel class of semiconductor metamaterials that employ a strongly anisotropic dielectric function to achieve negative refraction in the midinfrared region of the spectrum, similar to

Halide glasses are of interest for long wavelength (>1micrometer) optical fiber applications because of potential low Rayleigh scatter and multiphonon losses.

In this paper we present a system for supporting fairness in IEEE 802.11 MAC layer while maintaining the overall throughput.

We present a framework for providing fair service and supporting QoS requirements in IEEE 802.11 networks with multiple access-points (APs).

In this paper we present a system for supporting fairness in IEEE 802.11 MAC layer while maximizing the overall throughput.

Broadband network deployments are taking off in Europe. At present these networks primarily support Internet traffic. This service is provided at relatively low speeds and fixed prices.

When migrating a service from a legacy system to a target platform, the tasks associated to the introduction of the new platform should be distinguished from the subscriber data migration itself.

The annealing behavior of the interstitial boron atom in crystalline silicon has been explored in DLTS studies.

We calculate total configurational energies for interstitial aluminum and silicon in silicon.
