The aim of the thesis is to develop a model, based on well known physical and empirical formulas, to simulate the heat load on a rink of artificially frozen ice. A comparison of the results from this model and the results from other methods to determine heat load of the rink is made. The model calculates the heat load from convection, long wave radiation from the air temperature and from the sky t

Today, due to the fast development of Internet Protocol TV (IPTV), which is the combination of IP technology and two-way broadband networks, the telecom industry is undergoing fundamental changes. Network operators and service providers around the world are making significant investments in order to deliver digital video content to their subscribers. Video puts very high demands on the network and

[Context & motivation] This research preview paper presents ongoing work on the metamodel of a free software requirements modeling tool called reqT that is developed in an educational context. The work aims to make an initial validation of a survey instrument that elicits views on the metamodel of the reqT tool, which aims to engage computer science students in Requirements Engineering (RE) th

OBJECTIVE: On December 8-9, 2014, the Pennington Biomedical Research Center convened a scientific symposium to review the state-of-the-science and future directions for the study of developmental programming of obesity and chronic disease. The objectives of the symposium were to discuss: (i) past and current scientific advances in animal models, population-based cohort studies, and human clinical

Drilling of a deep borehole does not normally allow for hydrologic testing during the drilling period. It is only done when drilling experiences a large loss (or high return) of drilling fluid due to penetration of a large-transmissivity zone. The paper proposes the possibility of conducting flowing fluid electrical conductivity (FFEC) logging during the drilling period, with negligible impact on

There is consistent evidence in the literature that an average employee's age is negatively related to firm-level innovativeness. This observation has been explained by older employees working with outdated technological knowledge and being characterized by reduced cognitive flexibility. We argue that firms can mitigate this effect through employee turnover. In particular, turnover of R&D work

Children who grow up with a parent with an addiction and/or mental illness are at higher risk of developing the same disorder. There are children who even when growing up under rough conditions succeed to overcome their childhood and grow up to be “normal” citizens. These children have a high level of resilience and are usually referred to as Superkids. The aim of this study was to understand what

Urban environments are rapidly growing worldwide with severe consequences to animals and plants residing in our cities. Some of the most well-studied urban wildlife is passerine birds, where a wide array of effects have been documented; smaller clutches, earlier breeding, shorter telomeres and oxidative stress are just some costs among numerous others. Yet, few studies have so far investigated the

Girls continue to be less interested in studying engineering than boys. Previous research has found that this gender difference is in part due to girls’ lower self-efficacy, lower sense of belonging in engineering and higher communal goals, which they perceive are difficult to fulfil in engineering. This study tested if a role model intervention can improve these factors in female high school stud

Fewer hospital beds and an increasing amount of patients with comorbidities calls for more advanced care being performed in the municipal home care. This increases the incidence of acute illnesses needing to be assessed by the nurse in municipal home care. An early and structured assessment is crucial for making correct and efficient decisions about the level of care that the patient needs. This s

Denna uppsats handlar om det aktiebolagsrättsliga begreppet värdeöverföring. Uppsatsen har sitt fokus på förtäckt värdeöverföring i ett koncernsammahang. Förtäckt värdeöverföring definieras i 17 kap. 1§ 1st. p.4 enligt följande; annan affärshändelse som medför att bolagets förmögenhet minskar och inte har rent affärsmässig karaktär för bolaget. Uppsatsen ämnar skapa en djupare förståelse och kuns

Our paper starts with a reflection on how the classic left and right-wing scale has become less relevant in modern politics. Instead, we argue that completely new divisions in society are being formed. Examples are issues of globalization, immigration and identity. These are questions often associated with the other axis of the political scale - conservative or progressive. To examine this in prac

Syftet med den aktuella studien var att undersöka om en intervention i positiv psykologi kunde leda till ett ökat välbefinnande hos elever i årskurs 1-6 på en svensk grundskola. Det undersöktes även om interventionen hade olika effekt i olika årskurser. Frågeformulär administrerades före och efter interventionen. Enstaka frågor om trivsel i skolan, psykosomatiska besvär och mobbning samt Students’

Den föreliggande studien grundades på tidigare forskning som funnit samband mellan email-användande och stressrelaterade sjukdomar, såsom utbrändhet och emotionell utmattning, samt en ökad daglig stress. Syftet med studien var att undersöka om det finns ett samband mellan email overload, copingstrategier och upplevd stress. Vidare frågeställningar som studien baserades på var ifall det finns ett sThe present study was based on previous research that has found connections between email usage and stress-related diseases, such as burnout and emotional exhaustion, as well as an increased daily stress. The purpose of the study was to investigate whether there is a connection between email overload, coping strategies and percieved stress. Further issues on which the study was based was if there

In the name of collaboration : The significant meaning of a consultation team from a neoinstitutional perspective. Collaboration between human service organizations is to be considered desirable however also known to be hard to accomplish. The aim of this case study was to examine the phenomenon of inter-organizational collaboration by describing and analyzing the significant meaning of a consult
