Turbulence-Resistant FSO Communication Using a Few-Mode Pre-Amplified Receiver

Leveraging recent advances in space-division multiplexing, we propose and demonstrate turbulence-resistant free-space optical communication using few-mode (FM) pre-amplified receivers. The rationale for this approach is that a distorted wavefront can be decomposed into a superposition of the fundamental Gaussian mode and high-order modes of a few-mode fiber. We present the ...

Numerical investigation of nanoporous evaporation using direct simulation Monte Carlo

Evaporation is an effective cooling mechanism widely exploited in the thermal management of modern electronic devices, with a growing interest in the evaporation process in thin film based nanoporous membrane technologies. At such scales, classical approaches fail and one requires solutions of the Boltzmann equation; these are obtained here using ...

A Post-5G Network to Break the Eight Fallacies of Distributed Computing

To host time-sensitive applications in video-dominated networks, 5G calls for a tighter convergence of IT and (optical) transport. Our dynamic deterministic networks are serious candidates and could overturn the famous eight fallacies of distributed computing.

Finding a maximum clique in dense graphs via ?<sup>2</sup> statistics

The maximum clique extraction problem finds extensive application in diverse domains like community discovery in social networks, brain connectivity networks, motif discovery, gene expression in bioinformatics, anomaly detection, road networks and expert graphs. Since the problem is NP-hard, known algorithms for finding a maximum clique can be expensive for large ...

Optimizing LTE Networks and Communication Protocols of Reliable Real-time Applications

We study the options for supporting reliable realtime use cases using commercial Long Term Evolution (LTE) networks. We consider two different approaches to facilitate such services, namely Network Optimization that is available to the operator, and optimizing the Application Communication Protocol which is available to the application developer. To test ...

Machine Learning-Based in-band OSNR Estimation from Optical Spectra

Measuring the optical signal to noise ratio (OSNR) at certain network points is useful for failure handling, for single connection but also global network optimization. Estimating OSNR is inherently difficult in dense wavelength routed networks where connections accumulate noise over different paths and tight filters do not allow the observation ...

A headache interface. My experience with the brain computer interface - from a complete failure to a moderate success.

Presumably a Brain Computer Interface may be used (among many other applications) for curing chronic headache. But BCIs are also good in giving you one. I tried out a consumer-grade electroencephalography set offering a C++ API. This meant lots of integration testing, many failures and moderate successes.

Networking and Routing in Space Division Multiplexed Systems

Optical networks serve as the cornerstone of our connected society, enabling the information superhighway that delivers the Internet all across the globe. As the number of users and data services increase, the network technology and architecture must adapt for it to continue to efficiently and economically support the larger traffic ...

Interoperability Solution for IEEE 802.1X based Authentication unsupported Customer Premises Equipment

8021x based authentication enables node devices in network to perform AAA operation (Authentication, Authorization and Accounting). Authentication is made possible by a handshake mechanism between the node device and the CPE connected by means of a challenge of request and response exchange. The node device sends out a challenge request ...
