Neuroenergetics: How energy constraints shape brain function / Jolivet, Renaud Blaise (speaker) (CERN)
The nervous system consumes a disproportionate fraction of the resting body’s energy production. In humans, the brain represents 2% of the body’s mass, yet it accounts for ~20% of the total oxygen consumption. [...]

Hadoop Tutorial - Efficient data ingestion / Baranowski, Zbigniew (speaker) (CERN) ; Lanza Garcia, Daniel (speaker) (CERN)
The Hadoop ecosystem is the leading opensource platform for distributed storage and processing of "big data". The Hadoop platform is available at CERN as a central service provided by the IT department. Real-time data ingestion to Hadoop ecosystem due to the system specificity is non-trivial process and requires some efforts (which is often underestimated) in order to make it efficient (low latency, optimize data placement, footprint on the cluster). In this tutorial attendees will learn about: The important aspects of storing the data in Hadoop Distributed File System (HDFS).  Data ingestion techniques and engines that are capable of shipping data to Hadoop in an efficient way. Setting up a full data ingestion flow into a Hadoop Distributed Files System from various sources (streaming, log files, databases) using the best practices and components available around the ecosystem (including Sqoop, Kite, Flume, Kafka).

First ALICE results on quarkonium production at Run 2 energies / Pereira Da Costa, Hugo Denis Antonio (speaker) (CEA/IRFU,Centre d'etude de Saclay Gif-sur-Yvette (FR))
Quarkonium production in hadronic collisions (either proton-proton or heavy ions) has been extensively studied in both fixed target and collider experiments. It is understood as the production of a heavy quark pair (ccbar or bbar depending on the quarkonium state) in a hard scattering process which occurs early in the collision, followed by the evolution of this quark pair into a colorless bound state.

Search for magnetic monopoles with the MoEDAL prototype trapping detector in 8 TeV proton-proton collisions at the LHC / Mermod, Philippe (speaker) (Universite de Geneve (CH))
The MoEDAL experiment is designed to search for magnetic monopoles and other highly-ionising particles produced in high-energy collisions at the LHC. The largely passive MoEDAL detector, deployed at Interaction Point 8 on the LHC ring, relies on two dedicated direct detection techniques. [...]

Hadoop Tutorials - Hadoop Foundations / Lanza Garcia, Daniel (speaker) (Ministere des affaires etrangeres et europeennes (FR)) ; Baranowski, Zbigniew (speaker) (CERN)
The Hadoop ecosystem is the leading opensource platform for distributed storage and processing of "big data". The Hadoop platform is available at CERN as a central service provided by the IT department. This tutorial organized by the IT Hadoop service, aims to introduce the main concepts about Hadoop technology in a practical way and is targeted to those who would like to start using the service for distributed parallel data processing. The main topics that will be covered are: Hadoop architecture and available components How to perform distributed parallel processing in order to explore and create reports with SQL (with Apache Impala) on example data. Using a HUE - Hadoop web UI for presenting the results in user friendly way. How to format and/or structure data in order to make data processing more efficient - by using various data formats/containers and partitioning techniques (Avro, Parquet, HBase). Best practices in this area will be also discussed   Attendees will have the possibility to access a test Hadoop system where they will be able to perform hands-on exercises.
