Opin vísindi er varðveislusafn vísindaefnis og doktorsritgerða í opnum aðgangi á vegum íslenskra háskóla og Landsbókasafns Íslands - Háskólabókasafns.
Opinn aðgangur að rannsóknaniðurstöðum er í samræmi við 10. gr. laga nr. 3/2003 um opinberan stuðning við vísindarannsóknir sem og kröfur innlendra og erlendra rannsóknasjóða. Markmiðið með opnum aðgangi er að niðurstöður rannsókna séu aðgengilegar sem flestum óhindrað og án endurgjalds á rafrænu formi. Vistun í varðveislusafninu er varanleg og ætlað að tryggja aðgang að vísindaefni íslenskra háskóla í opnum aðgangi um ókomna tíð. Varðveislusafnið Opin vísindi er tengt við rannsóknagáttina IRIS og rannsóknaniðurstöður í opnum aðgangi sem eru skráðar í IRIS eru um leið vistaðar og gerðar aðgengilegar til framtíðar í varðveislusafninu. Með því að safna þessu efni saman í eitt safn verður aðgangur að því einfaldur og þægilegur fyrir alla sem vilja kynna sér það og geta þannig notið þess öfluga vísindastarfs sem fram fer í háskólum landsins.
Varðveislusafnið er OpenAIRE / OpenAIREplus samhæft og samrýmist kröfum sem gerðar eru um birtingu rannsóknaniðurstaðna úr verkefnum sem styrkt eru úr evrópsku rannsóknaáætlununum FP7 og H2020.

Open Challenges of Interactive Video Search and Evaluation
(Association for Computing Machinery, Inc, 2022-10-10) Loko, Jakub; Schoeffmann, Klaus; Bailer, Werner; Rossetto, Luca; Jónsson, Björn Þór; Department of Computer Science
During the last 10 years of Video Browser Showdown (VBS), there were many different approaches tested for known-item search and ad-hoc search tasks. Undoubtedly, teams incorporating state-of-the-art models from the machine learning domain had an advantage over teams focusing just on interactive interfaces. On the other hand, VBS results indicate that effective means of interaction with a search system is still necessary to accomplish challenging search tasks. In this tutorial, we summarize successful deep models tested at the Video Browser Showdown as well as interfaces designed on top of corresponding distance/similarity spaces. Our broad experience with competition organization and evaluation will be presented as well, focusing on promising findings and also challenging problems from the most recent iterations of the Video Browser Showdown.
Teaching project management in a virtual environment : The Virtual Scrum Simulator (ScrumSim)
(Association for Computing Machinery, 2022-10-08) Visescu, Ioana; Blindu, Alin; Radhakrishnan, Unnikrishnan; Kadenic, Maja; Chinello, Francesco; Koumaditis, Konstantinos
The Scrum Simulator (ScrumSim) is an interactive multiplayer VR simulation that places the participant in a virtual collaboration environment, in order to train them in the use of a project management methodology i.e., Scrum. In VR, the participants as a team, with the assistance of two avatars, perform intuitive tasks in sprints, cooperate, discuss, interact with the environment and receive feedback on their performance and tasks. The novelty of this approach lies not only in the unique design elements but also in the use of avatars and the utilisation of in-game data (task efficiency and communication).
Adopting digital government shared-services centers : A case from Iceland
(Association for Computing Machinery, 2022-10-04) Hjaltalin, Illugi T.; Amaral, Luis; Soares, Delfina; Zheng, Lei; Department of Business and Economics
The overall objective of this study is to understand how shared services adoption by governments can affect public sector reforms and public value. In this ongoing research paper, a case study involving a deployment of a government digital shared-services center is outlined. The adoption process is analyzed through a framework inspired by systems theory and public value theory. Initial results suggest that networked collaborative governance in the form of cross-sector collaborations can play an important role in public value (co)creation. However, the findings also indicate a barrier to public innovation. This involves a zero-error culture in state agencies. In this context, strong leadership skills and diverse use of relevant administrative instruments at various stages in the innovation process are found to be critical factors for the successful adoption of shared services. This study contributes empirically and theoretically to the latest research on ICT and public value by scrutinizing a successful case of a shared-services unit within central government.
Decline in Running Performance in Highest-Level Soccer : Analysis of the UEFA Champions League Matches

It is widely recognized that there is a decline in match running performance (MRP) towards the end of matches. To clarify whether it is primarily a consequence of fatigue, pacing or situational influences, this study aimed to examine MRP across 15-min match periods for players on different playing positions. Players’ MRP (n = 244) were examined from the UEFA Champions League matches (n = 20) using a semiautomatic optical tracking system. Linear mixed models for repeated measures were adjusted to analyze MRP over the six 15-min match periods while controlling the influence of situational factors. No effects of match outcome, match location, team, and opponent quality on total distance (TD) and high-intensity running (HIR) for players in all playing positions were found (F = 0.03–2.75; all p > 0.05). Significant differences in TD (F = 17.57–53.01; η2 = 0.39–0.52, all large effect sizes) and HIR (F = 3.67–7.64; η2 = 0.05–0.19, small to medium effect sizes) among six 15-minute match periods were found for players in all playing positions. In addition, players in all playing positions covered less TD (d = 1.41–2.15, large to very large effect sizes) and HIR (d = 0.16–0.6, trivial to medium effect sizes) in the last compared to the first 15-min match period. No differences in TD and HIR between the last two match periods in the second half were observed. This study confirmed that soccer players reduce MRP towards the end of matches, and suggest that the decline of MPR in highest-level soccer may be a consequence of pacing strategies.
Encodability and Separation for a Reflective Higher-Order Calculus
(2022-09-06) Lybech, Stian; Department of Computer Science
The ρ-calculus (Reflective Higher-Order Calculus) of Meredith and Radestock is a π-calculus-like language with some unusual features, notably, structured names, runtime generation of free names, and the lack of an operator for scoping visibility of names. These features pose some interesting difficulties for proofs of encodability and separation results. We describe two errors in a previously published attempt to encode the π-calculus in the ρ-calculus by Meredith and Radestock. Then we give a new encoding and prove its correctness, using a set of encodability criteria close to those proposed by Gorla, and discuss the adaptations necessary to work with a calculus with runtime generation of structured names. Lastly we prove a separation result, showing that the ρ-calculus cannot be encoded in the π-calculus.
