CLAP: Compact Labeling scheme for Attribute-based IoT Policy control

In order to create services using IoT devices, the underlying network infrastructure must support large number of such devices with different underlying protocols, and diverse requirements from the service applications (privacy, reliability and QoS guarantee, etc.). Many of these requirements can be realized by implementing an in-network packet forwarding policy ...

Import2vec: Learning embeddings for Software Libraries

We consider the problem of developing suitable machine learning representations for software libraries. From other fields that heavily use machine learning we know such representations are key to the performance of downstream learning tasks. For instance, in natural language processing (NLP) the use of word embeddings ("word vectors") enables machine ...

Anticipatory Resource Allocation and Trading in a Sliced Network

Dynamically sharing the network resources in a sliced multi-tenant network can provide cost efficient solutions that are able to guarantee specific service requirements for 5G and beyond networks. By automatizing the negotiations between tenants and infrastructure providers over the shared resources, it is possible to maximize the flexibility of the ...

Optimizing Optical Interconnects: Digital Predistortion and Postequalization Techniques in Optical Communications

For the past few decades, we have witnessed explosive growth in data consumption in our everyday lives. While consumers rely more and more on wireless connections to obtain all these data, backbone data networks and infrastructures now depend largely on optical connectivity.

The next generation platform as a service: Composition and deployment of platforms and services

The emergence of widespread cloudification and virtualisation promises increased flexibility, scalability, and programmability for the deployment of services by Vertical Service Providers (VSPs). This cloudification also improves service and network management, reducing the Capital and Operational Expenses (CAPEX, OPEX). A truly cloud-native approach is essential, since 5G will provide a ...

Digital predistortion and post equalization techniques in optical communications

Introduction For the past few decades, we have witnessed explosive growth in data consumption in our everyday life. While the consumers have been reaching out to such data more and more in wireless connection, the backbone data networks and infrastructures have been largely enabled and transformed by optical connectivity.

Selective Redundant MP-QUIC for 5G Mission Critical Wireless Applications

In this paper we propose a multi-connectivity protocol suited for for mission critical applications that use wireless 5G multi-UE devices. It extends the MP-QUIC protocol by adding selective data duplication with strict prioritization to support a mix of critical and non-critical applications on a single end-to-end connection; e.g. suitable for ...

Per-sample Prediction Intervals for Extreme Learning Machines

Prediction Intervals in supervised Machine Learning bound the region where the true outputs of new samples may fall. They are necessary for separating reliable predictions of a trained model from near random guesses, minimizing the rate of False Positives, and for other problem-specific tasks in applied Machine Learning. Stochastic projection ...

Digital networks at the nexus of productivity growth

This paper takes a fresh look at the debate over the relationship between digital technology and productivity. The argument of economic historian Robert J. Gordon is that digital technology will not lead to increases in productivity such as we saw in the last century, based on his analysis of the ...

Weighted Sum-Rate Maximization in Multi-Carrier NOMA with Cellular Power Constraint

Non-orthogonal multiple access (NOMA) has re- ceived significant attention for future wireless networks. NOMA outperforms orthogonal schemes, such as OFDMA, in terms of spectral efficiency and massive connectivity. The joint subcarrier and power allocation problem in NOMA is NP-hard to solve in general, due to complex impacts of signal superposition ...

Silver Tarnishing Mechanism Revealed by Molecular Dynamics Simulations

KGaA, Weinheim The mechanism of silver?oxygen and silver?sulfur reactions is revealed by means of molecular dynamics simulations, performed with reactive force fields purposely built and extensively tested against quantum-chemical results. Different reaction mechanisms and rates for Ag?O and Ag?S emerge. This study solves the long-lasting question why silver exposed to ...

A Framework for Privacy Quantification: Measuring the Impact of Privacy Techniques Through Mutual Information, Distance Mapping, and Machine Learning
