An early characterisation of wearing variability on motion signals for wearables

We explore a new variability observed in motion signals acquired from modern wearables. Wearing variability refers to the variations of the device orientation and placement across wearing events. We collect the accelerometer data on a smartwatch and an earbud and analyse how motion signals change due to the wearing variability. ...

Formation of protein networks between mucins: Molecular dynamics study based on the interaction energy of the system

Molecular dynamics simulations have been performed for a model aqueous solution of mucin. As mucin is a central part of lubricin, a key component of synovial fluid, we investigate its ability to form cross-linked networks. Such network formation could be of major importance for the viscoelastic properties of the soft-matter ...

OSAA: On-Demand Source Authentication and Authorization in the Internet

Lack of ability to control inbound traffic is one of the essential security vulnerabilities of the present Internet. It is the consequence of the fundamental fact that the Internet was built as a highly distributed public network, in which every node may freely send arbitrary traffic to any other node. ...

FLEXIBLE 50 GBPS PON BASED ON CAP-4 AND PAM-4 WITH USER INTERLEAVING

In this paper we propose a flexible 50G PON based on CAP (carrier less amplitude phase) modulation and compare this with our user interleaving PAM-4 scheme at 50G as well.

IEEE 802.11 Extremely High Throughput: The Next Generation of Wi-Fi Technology Beyond 802.11ax

Wireless-Fidelity (Wi-Fi) is continuously innovating to cater for the upcoming customer demands, driven by the digitalisation of everything, both in the home as well as the enterprise and hotspot spaces. In this article, we introduce to the wireless community IEEE 802.11 extremely high throughput (EHT), the next generation of Wi-Fi ...

Introduction to the JOCN Special Issue on Low-Margin Optical Networks

This special issue contains a collection of invited and contributed papers on low-margin optical networks by operators, equipment vendors and academic research labs.

On the Benefits of Network-Level Cooperation in Millimeter-Wave Communications

Relaying techniques for millimeter-wave wireless networks represent a powerful solution for improving the transmission performance. In this paper, we quantify the benefits in terms of delay and throughput for a random-Access multi-user millimeter-wave wireless network, assisted by a full-duplex network cooperative relay. The relay is equipped with a queue for ...

Experimental Analysis of NB-IoT Performance

Narrowband Internet of Things (NB-IoT) provides a set of specifications with the potential to support new IoT use cases within the cellular networks. In several IoT use cases, the User Equipment (UE) must be reachable even if it is deployed in remote locations or indoor environments. NB-IoT focuses on low-cost ...

A D-band SiGe BiCMOS Chipset with Antenna-on-Glass Module for Spectrally-Efficient and Low-Cost Wireless Backhaul

Two D-band SiGe BiCMOS TRX ICs operating at 115-155GHz and 135-170GHz, respectively, are presented. The ICs can deliver Psat >13dBm and have a measured average NF of 8dB. A 1-meter 150-GHz wireless TX-link with a 64-element antenna-on-glass module of >20 dBi gain is demonstrated. Measured 256-QAM 8/16Gb/s (EVM = 3.8/5.3%) ...

Cooperative AI-based e2e Network Slice Scaling

The 5G network Slicing provides an end-to-end virtual network with dedicated capacity and other service specific QoS characteristics such as delay, response time, or service availability. This calls for coordinated and flexible resource control mechanisms spanning across multiple domains involved in the e2e service chain. In this demo, we focus ...

Stability and performance bounds in cyclic networks using newtork calculus

With the development of real-time systems and of new wire less communication technologies having strong requirements on latencies and reliability, there is a need to compute deterministic performance bounds in networks. This paper focuses on the performance guarantees and stability conditions of networks with cyclic dependencies in the net work ...

Own Linux for Raspberry Pi

Tutorial how to roll own Linux distribution. As an example platform Raspberry Pi Zero was choose. Article starts from configuring cross compiler. Then compilation of U-Boot and Kernel is described.

Model-free Training of End-to-end Communication Systems

The idea of end-to-end learning of communication systems through neural network-based autoencoders has the shortcoming that it requires a differentiable channel model. We present in this paper a novel learning algorithm which alleviates this problem. The algorithm enables training of systems with an unknown channel model or with non-differentiable components. ...

Nicotine matters in predicting subsequent smoking after e-cigarette experimentation: A longitudinal study among Finnish adolescents

© 2019 The Authors Background: Several studies indicate an association between e-cigarette use and subsequent smoking among youth. However, most previous studies lack measures of the nicotine content of e-liquid and have not usually measured regular smoking. Methods: We tested the association between e-cigarette use, with and without nicotine, and ...

Fiber To The Tap: Pushing Coaxial Cable To Its Limit

We explore the potential of a future cable access technology that pushes the capacity of the coaxial cable network to its limits. We will show that it is possible to achieve symmetric data rates of multiple tens of gigabit per second, using the same coaxial drop cables in use today ...

High Speed Copper and Coaxial Broadband

of deeper fiber is facilitated by the ability to leverage the remaining copper drop for providing ubiquitous gigabit access to everyone within the service area. In contrast, fiber roll-outs that don't leverage the copper network are regional - as region-by-region is upgraded to full fiber, the remaining regions are under-served. ...

Protecting photonic quantum states using topology

The use of topology to protect quantum information is well-known to the condensed-matter community and, indeed, topological quantum computing is a bursting field of research and one of the competing avenues to demonstrate that quantum computers can complete certain problems that classical computers cannot. In photonics, however, we are only ...
