Resilience in Critical infrastructure within the energy sector of Norway
2021
Master's thesis in Cyber security (IS507) This thesis investigates what are the characteristics of resilience within the energy sector, as well as what are the "best” known practices being used to increase awareness of the employees. By looking at the existing literature and finding differences between how the energy sector in Norway vs other nations approaches resilience. There is a difference in Norway's more decentralized power grid, where many smaller power stations supply energy, compared to other nation with single large power station. This influences how they will approach resilience. The study uses a qualitative research approach, with semi-structured interviews to gather data from …
Praktyczne zarządzanie energią w przedsiębiorstwie
2016
Zarządzanie energią w przedsiębiorstwie może być skutecznym narzędziem do zmniejszenia zapotrzebowania energii pierwotnej oraz końcowej przedsiębiorstwa, a tym samym poprawy konkurencyjności firmy. Niniejsza praca przedstawia przykłady zarządzania energią zastosowane w przedsiębiorstwach oraz efekty przeprowadzonych audytów energetycznych wskazujących na poprawę efektywności energetycznej. W pracy zestawiono z jednej strony niektóre wymagania normy PN-EN ISO 50001:2011,kupiające się na przeglądzie energetycznym i monitorowaniu zużycia energii oraz wymagania Ustawy o efektywności energetycznej z 20 maja 2016 wymagającej przeprowadzenia audytu energetycznego przedsiębiorstwa, a drugiej strony…

"Table 2" of "Observation of $Z$ production in proton-lead collisions at LHCb"
2014
The forward-backward ratio measured in the overlap region 2.5 < ABS(YRAP) < 4.0. The first uncertainty is statistical, defined as the 68% confidence interval with symmetric coverage. The second uncertainty is systematic and includes the uncertainty on the acceptance correction factor, BETA, for the difference in the detector acceptance of the muons between the forward and backward directions.
"Table 1" of "Observation of $Z$ production in proton-lead collisions at LHCb"
2014
The measured Z production cross-sections in proton-lead collisions, measured in the fiducial region defined in the table, in the forward and backward directions. The statistical uncertainty is defined as the 68% confidence interval with symmetric coverage assuming that the number of candidates follows a Poisson distribution.
Efeitos das práticas verdes na lealdade: proposta de um modelo para o segmento hoteleiro colombiano
2021
Resumen El propósito de este estudio fue analizar la incidencia de las prácticas verdes como impulsoras para generar confianza, satisfacción y lealtad en los huéspedes. Para ello, a partir de una muestra de 302 huéspedes de hoteles en Bogotá, Colombia, se estimó un modelo de ecuaciones estructurales a través de la regresión de mínimos cuadrados parciales. Los resultados obtenidos evidencian que las prácticas sostenibles contribuyen al aumento de la confianza y la satisfacción de los huéspedes, y que estas, a su vez, influyen positivamente en su lealtad hacia el hotel. Además, dichos resultados ponen de manifiesto que una comprensión más profunda del perfil de los turistas medioambientalment…

Political Participation and Democracy in the Information Age: Effects of ICT-Based Communication Forms between the Authorities and the Citizens on Tr…
2009
Bidrag på konferanse: The Third International Conference on Digital Society ICDS 2009 1-7 February 2009 Cancun, Mexico The main trends concerning the traditional channels of participation are reduced voting turnout, reduced participation in political parties, stable participation in associations and increased citizen contact. The influence of ICT based form of communication on the relations between the authorities and the citizens are heavily influenced by the role of the citizens designed by the authorities. If the citizens are treated as customers the authorities are pursuing a consultative model focusing on creating an effective administration. The flow of information is uni linear; howe…
Towards safe reinforcement-learning in industrial grid-warehousing
2020
Abstract Reinforcement learning has shown to be profoundly successful at learning optimal policies for simulated environments using distributed training with extensive compute capacity. Model-free reinforcement learning uses the notion of trial and error, where the error is a vital part of learning the agent to behave optimally. In mission-critical, real-world environments, there is little tolerance for failure and can cause damaging effects on humans and equipment. In these environments, current state-of-the-art reinforcement learning approaches are not sufficient to learn optimal control policies safely. On the other hand, model-based reinforcement learning tries to encode environment tra…
A Framework for Assessing the Condition of Crowds Exposed to a Fire Hazard Using a Probabilistic Model
2014
Published version of an article in the journal: International Journal of Machine Learning and Computing. Also available from the publisher at: http://dx.doi.org/10.7763/IJMLC.2014.V4.379 open Access Allocating limited resources in an optimal manner when rescuing victims from a hazard is a complex and error prone task, because the involved hazards are typically evolving over time; stagnating, building up or diminishing. Typical error sources are: miscalculation of resource availability and the victims’ condition. Thus, there is a need for decision support when it comes to rapidly predicting where the human fatalities are likely to occur to ensure timely rescue. This paper proposes a probabil…
