Beyond bin-packing combining bin-packing algorithms tailored for automated software testing: ROST-algorithm
Førre, Martina Rebekka (ACIT;2022, Master thesis, 2022)In this project, bin-packing has been analysed as a way of better utilizing resources in a continuous integration system in order to increase its efficiency. The worst-fit, best-fit, next-fit and first-fit algorithms ... -
The CAST-algorithm bridging green energy with continuous testing.
Stølen, Ingvild (ACIT;2021, Master thesis, 2021)In society today, we are dependent on software in our daily lives. One key factor of success when creating this software is the use of automated testing. At the same time, we have a large challenge in reducing greenhouse ... -
Déjà vu - Predicting the number of players in online games through normalization of historical data
Tyvand, Jon-Erik; Begnum, Kyrre; Hammer, Hugo Lewi (Chapter; Peer reviewed, 2011)A key factor to delivering a good online gaming experience is to have sufficient server resources relative to the number of players online. In this work, we present a simple profiling technique which allows effective ... -
Effective live migration of virtual machines using partitioning and affinity aware-scheduling
Yazidi, Anis; Ung, Fredrik; Haugerud, Hårek; Begnum, Kyrre (Computers and Electrical Engineering;volume 69 (2018), Journal article; Peer reviewed, 2018-07-11)During maintenance and disaster recovery scenarios, Virtual Machine (VM) inter-site migrations usually take place over limited bandwidth—typically Wide Area Network (WAN)—which is highly affected by the amount of inter-VM ... -
Enhancing creativity and play through accessible projector-based interactive PC-control touch technology
Begnum, Miriam Eileen Nes; Finstadsveen, Johan; Begnum, Kyrre (The proceedings of Unitech : International Conference on Universal Technologies;2010, Chapter; Peer reviewed, 2010)Standard computer peripherals are often challenging to use for mobility impaired, and in particular controlling computer mouse movements efficiently and without risking strain injuries. Projected touch screen technology ... -
Evading a Machine Learning-based Intrusion Detection System through Adversarial Perturbations
Fladby, Torgeir; Haugerud, Hårek; Nichele, Stefano; Begnum, Kyrre; Yazidi, Anis (RACS: Research in Applied Computation Symposium; RACS '20: International Conference on Research in Adaptive and Convergent Systems, Chapter; Peer reviewed; Conference proceeding, 2020-10)Machine-learning based Intrusion Detection and Prevention Systems provide significant value to organizations because they can efficiently detect previously unseen variations of known threats, new threats related to known ... -
