Electronic Ticket and Check-in System for Indico Conferences

Project Specification: This project should build on the existing participant registration module of Indico and provide additional functionalities for managing the check-in process. While in small conferences it is easy to keep track of participants with a simple paper list, such techniques become inefficient when the need to scale the process up arises. Therefore Indico’s participant registration module would be extended with the functionality to generate electronic tickets. This will allow conference organizers to keep track of attendees after they finish the registration process. As part of this project it is also necessary to develop a mobile application that will be used to scan the electronic tickets, identify the user and mark them as checked in when they arrive at the conference. Additionally Indico’s HTTP API would be extended to be used by the mobile application to retrieve data about conferences and attendees. Abstract: The main goal of this project is to simplify the check-in process for conferences that use the Indico conference management system. This is archived by extending Indico’s core to include electronic ticket generation functionality and developing a mobile application that is used to scan the electronic tickets during the check-in process. Indico’s HTTP API is also extended to provide the mobile application with the necessary data

Finding Similar Mail Conversations Using Locality Sensitive Hashing

Rad opisuje različite porodice algoritama sažimanja neosjetljivog na lokalne promjene. Opisane su implementacije MinHash, SimHash, Kosinus i Nilsimsa porodica. Poseban naglasak je stavljen na otkrivanje sličnih poruka elektroničke pošte korištenjem LSH algoritama. Ispitana je kvaliteta različitih porodica LSH algoritama sa obzirom na parametre algoritama. Zbog velike količine poruka potrebnih za analizu, u radu je opisan postupak dohvata i spremanja poruka sa javno dostupnih grupa i Stack Exchange stranica.This paper describes different families of locality sensitive hashing algorithms. Implementations for the MinHash, SimHash, Cosine and Nilsimsa families are described. An emphasis was put on finding similar emails using LSH algorithms. The quality of different LSH algorithms was tested with regards to algorithm parameters. Because of the need for a big amount of emails for testing, a procedure for fetching and saving emails from publicly accessible mailing groups and Stack Exchange sites is described

Upgrade of the ATLAS Control and Configuration Software for Run 2

The ATLAS data acquisition (DAQ) system is controlled and configured via a software infrastructure that takes care of coherently orchestrating the data taking. While the overall architecture, established at the end of the 90’s, has proven to be solid and flexible, many software components have undergone a complete redesign or re-implementation in 2013/2014 in order to fold-in the additional requirements that appeared in the course of LHC’s Run 1, to profit from new technologies and to re-factorise and cleanup software. This paper describes the approach that was taken to plan, organise and carry out this software upgrade project. It highlights the main technical choices that have guided the overall work, describes the major achievements and outlines how the control and configuration software may be further improved or re-shaped in the future
