Update of the Offline Framework for AugerPrime

Opis: Work on the Offline Framework for the Pierre Auger Observatory was started in 2003 to create a universal framework for event reconstruction and simulation. The development and installation of the AugerPrime upgrade of the Pierre Auger Observatory require an update of the Offline Framework to handle the additional detector components and the upgraded Surface Detector Electronics. The design of the Offline Framework proved to be sufficiently flexible to accommodate the changes needed to be able to handle the AugerPrime detector. This flexibility has been a goal since the development of the code started. The framework separates data structures from processing modules. The detector components map directly onto data structures. It was straightforward to update or add processing modules to handle the additional information from the new detectors. We will discuss the general structure of the Offline Framework, explaining the design decisions that provided its flexibility and point out the few of the features of the original design that required deeper changes, which could have been avoided in hindsight. Given the disruptive nature of the AugerPrime upgrade, the developers decided that the update for AugerPrime was the moment to change also the language standard for the implementation and move to the latest version of C++, to break strict backward compatibility eliminating deprecated interfaces, and to modernize the development infrastructure. We will discuss the changes that were made to the structure in general and the modules that were added to the framework to handle the new detector components.

Performance of a proposed event-type based analysis for the Cherenkov Telescope Array

Opis: The Cherenkov Telescope Array (CTA) will be the next-generation observatory in the field of very-high-energy (20 GeV to 300 TeV) gamma-ray astroparticle physics. Classically, data analysis in the field maximizes sensitivity by applying quality cuts on the data acquired. These cuts, optimized using Monte Carlo simulations, select higher quality events from the initial dataset. Subsequent steps of the analysis typically use the surviving events to calculate one set of instrument response functions (IRFs). An alternative approach is the use of event types, as implemented in experiments such as the Fermi-LAT. In this approach, events are divided into sub-samples based on their reconstruction quality, and a set of IRFs is calculated for each sub-sample. The sub-samples are then combined in a joint analysis, treating them as independent observations. This leads to an improvement in performance parameters such as sensitivity, angular and energy resolution. Data loss is reduced since lower quality events are included in the analysis as well, rather than discarded. In this study, machine learning methods will be used to classify events according to their expected angular reconstruction quality. We will report the impact on CTA high-level performance when applying such an event-type classification, compared to the classical procedure.

The DreamTogether Machine : The DreamTogether Machine
Peter Purg, 2016, umetniška poustvaritev

Opis: The DreamTogether Machine (2016) was a migrating ideation event, supported by Gruentaler9 (Teena Lange), The Space Berlin (Rawan Hourani, Issa Khatib), the IDEATE.me project (co-fin. by European Commission), inspired by the FEI "Transformation Through Innovation" conference and MyMachneGlobal;moderated by pETER Purg of University of Nova Gorica, School of Arts, on October 6, 18 - 21h, at Gruentaler9, Berlin, Germany. A dozen of MachineDreamers -- mixed between the most propulsive innovators from the West, and the most promising young immigrants from the East -- Together drafted Machines, such as they dream of! And then, they might even come true... The event was directly linked to the presentation of Peter Purg at the 10th FEI (Front End of Innovation) Conference in Berlin, Germany (same day 12:15 - 13:00, at which hi-profile (creative) industry representatives have chosen to take part in "The Dream Together Machine" event (same day 18:00 - 21:00).
