The Nornir run-time system for parallel programs using Kahn process networks on multi-core machines—a flexible alternative to MapReduce
TL;DR: Nornir is based on the formalism of Kahn process networks, which is a shared-nothing, message-passing model of concurrency, and is deemed a simple and deterministic alternative to shared-memory concurrency.
Proceedings ArticleDOI
Automatic exposure for panoramic systems in uncontrolled lighting conditions: a football stadium case study
TL;DR: An approach is developed where the time between two temporal frames is exploited to communicate the exposures among the cameras where the authors achieve a perfectly synchronized array, and an analysis of the system and some experimental results are presented.
Proceedings ArticleDOI
Energy efficient video encoding using the tegra K1 mobile processor
TL;DR: Experiments indicate that an energy reduction can be achieved by running the video encoder on the lowest CPU frequency at which the platform achieves an encoding frame rate equal to the minimum frame rate of 25 Frames Per Second (FPS).

Docker-Based Evaluation Framework for Video Streaming QoE in Broadband Networks
Cise Midoglu,Anatoliy Zabrovskiy,Ozgu Alay,Daniel Hoelbling-Inzko,Carsten Griwodz,Christian Timmerer +5 more
TL;DR: An automatized measurement framework for evaluating video streaming QoE in operational broadband networks, using headless streaming with a Docker-based client, and a server-side implementation allowing for the use of multiple video players and adaptation algorithms.
Proceedings ArticleDOI
A Deep Learning Approach to Dynamic Passive RTT Prediction Model for TCP
TL;DR: This paper proposes and evaluates a novel deep learning-based model capable of dynamically predicting at real-time the RTT between the sender and receiver with high accuracy based on passive measurements collected at an intermediate node, taking advantage of the commonly used TCP timestamps.
