Cooperative Digital Magnetic-Elevation Maps by Small Autonomous Aerial Robots

One of the steps to provide fundamental data for planning a mining effort is the magnetic surveying of a target area, which is typically carried out by conventional aircraft campaigns. However, besides the high cost, fixed-wing aerial vehicles present shortcomings especially for drape flights on mountainous regions, where steep slopes ...

Dynamic In-band Self-backhauling for 5G Systems with Inter-cell Resource Coordination

? 2019, Springer Science+Business Media, LLC, part of Springer Nature. 5G systems are expected to utilize frequency bands above 6 GHz in the so-called millimeter-wave (mmWave) spectrum because of large bandwidths. It is well know that higher carrier frequency bands suffer from higher path loss attenuation. It addition, dynamic blockages ...

SLIDING TIMER EXPIRY TO REPORT FAULTS TO ETHERNET RING PROTECTION MECHANISM

The G.8032 Ethernet Ring Protection (ERP) protocol, detects failure and au-tomatically switches traffic path. To avoid different race conditions and un-necessary switching operations, it uses different timers. One of the static tim-er configured today is Hold-off timer. After detecting a failure ERPS will not switch immediately, it will wait for ...

Practical Aspects of Microservice Architecture presented on Code::Dive Nokia organized IT conference

In the presentation I will focus on practical consequences affecting system and entity when applying certain solutions as a part of microservice architecture, each design brings benefits, limitations, and risks to the system. I treat each solution as a contract with the system, and I will describe what kind of ...

[LT] How bananas could save your project. Understanding UX

Imagine you are about to release your product. You find it brilliant and dazzling. Hitting the market! This is your child and you are so proud! So proud till the first wave of feedback comes. Oh, really? This is not what you have expected. Now you are confused, devastated. Not ...

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.

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.

How to accidentally earn 5k $? Authorization bypass in Google Docs

What mistakes in architecture or implementation led to bug allowing you to bypass authentication in Google Docs app easily. I will show you a step-by-step case study how I found the bug in Google Forms. I will also share examples of similar bugs in other applications. You will learn how ...

Fundamental steps in prototyping with Machine Learning

The presentation gives a general introduction to what is machine learning, how it works, and how to get started followed by a practical example of how machine learning is used in Nokia for testing.

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 ...

Transmission of 30-GBd polarization-multiplexed probabilistically shaped 4096-QAM over 50.9-km SSMF

? 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement We demonstrate the transmission of a 30-GBd polarization-multiplexed probabilistically shaped 4096-ary quadrature amplitude modulation (QAM) signal over 50.9-km standard signal-mode fiber (SSMF), with a net single-carrier bit rate of 484.4 Gb/s carrying 16.1 information ...

Microservice Fingerprinting and Classification using Machine Learning

Application aware data centers promise various benefits for data center management in terms of resource provisioning, power estimation, network management and security protection. However, the emerging microservices make it challenging for data center operators to accurately identify what applications are run by tenants, due to the highly dynamic and heterogeneous ...

Compact optical frequency comb source based on a DFB butt-coupled to a silicon nitride microring

We demonstrate an integrated Kerr frequency comb source based on the butt coupling between a III-V DFB laser and a silicon nitride (Si3 N4) microresonator. The 30-dB bandwidth of the optical comb is measured to be 148.7 nm (18 THz), centered at 1576 nm, which is, to the best of ...

Estimation of groundwater storage from seismic data using deep learning

? 2019 European Association of Geoscientists & Engineers Convolutional neural networks can provide a potential framework to characterize groundwater storage from seismic data. Estimation of key components, such as the amount of groundwater stored in an aquifer and delineate water table level, from active-source seismic data are performed in this ...

Tiger: Wearable glasses for the 20-20-20 rule to alleviate computer vision syndrome

We propose Tiger, an eyewear system for helping users follow the 20-20-20 rule to alleviate the Computer Vision Syndrome symptoms. It monitors user's screen viewing activities and provides real-time feedback to help users follow the rule. For accurate screen viewing detection, we devise a light-weight multi-sensory fusion approach with three ...

Transmission of 30-GBaud Polarization-Multiplexed Probabilistically Shaped 4096-QAM over 50.9-km SSMF

We demonstrate the transmission of a 30-Gbaud PDM PS-4096-QAM signal, generated from 28-nm CMOS DACs, over 50.9-km SSMF, with a net single-carrier bit rate of 484.9 Gb/s
