In this paper we consider calibration of hydraulic models for district heating networks based on operational data. We extend previous theoretical work on the topic to handle real-world complications, namely unknown valve characteristics and hysteresis. We generate two datasets in the Smart Water Infrastructure Laboratory in Aalborg, Denmark, on which we evaluate the proposed procedure. In the firs
rapidly and on a large scale, judging from the very short introduction phase for late Slavic pottery and the absence of hybrid forms between this tradition and the local Scandinavian ware. Late Slavic ware became a Scanian cultural trait after only one generation; this tradition is today called “Baltic ware”, as it was produced outside the Slavic area by an increasing number of local potters. AfteThe existence of slavery in Viking-Age and high medieval Scandinavia is accepted as a fact. Law codes, literary sources and some few burials vouch for that. It is, however, more complicated to ascertain regional differences in the use of slaves, their ethnic identities and geographical distribution, as well as changes in the intensity of their exploitation over time. A new source, household potter
Sustained motivation is crucial to learning a second language (L2), and one way to support this can be through the mental visualisation of ideal L2 selves (Dörnyei & Kubanyiova, 2014). This paper reports on an exploratory study which investigated the possibility of using technology to create representations of language learners' ideal L2 selves digitally. Nine Chinese learners of L2 English we

This study analyzes how risk attitudes influence the agricultural productivity of men and women in a sub- Saharan African country, Burkina Faso. By using a large representative panel survey of farmers, the results show that as female farmers increase risk taking, the productivity of female-owned plots goes down.

In this study, we examine the way access to welfare provision for migrants is articulated discursively among three right-of-center parties in Sweden. For this, we suggest two theoretical advances. First, deploying the concept of the right-wing continuum, we highlight the gradual and reciprocal alignment between mainstream right-of-center and radical-right populist parties. Second, by resorting to

This thesis examines the norms, boundaries, and perceptions surrounding homosexuality in Swedish gay press between 1969 and 1973. The aim is to analyse how normative systems influenced the formation of identity, self-image, and sense of community among homosexual individuals. The aim is also to analyse how heteronormativity and the transgression of norms affected their relationship with society an
Many things have been written about Shakespeare’s comedies The Taming of the Shrew and Much Ado About Nothing yet few scholars have looked at the father-daughter relationships in any detail. This essay explores the father-daughter roles in these two plays and looks at the spectrum of contrasting relationships Shakespeare presents us with. The father roles in both plays are similar, but the daughte
Geomagnetically Induced Currents (GICs) arise from fluctuations in Earths magnetic field and can reach alarmingly high levels and cause malfunctions or blackouts in the power grids in which they occur. AF Klercker Alaküla and Lindahl invented a patented GIC immune transformer which eliminates the effects of GICs, though it is not known how this implementation will affect the transformers behavior
Denna kandidatuppsats är en komparativ studie som behandlar på vilket sätt Moderaterna respektive Socialdemokraterna använt sig av de digitala kanalerna Facebook och YouTube. Partierna har använt dessa i sina respektive valkampanjer och i denna uppsats undersöker vi hur politiska budskap förmedlas i sociala medier utifrån de politiska avsikter och ideologier som styr partierna. Denna uppsats vändeThis bachelor thesis analysis and compares the way two Swedish political parties, Moderaterna and Socialdemokraterna, used the digital channels Facebook and YouTube in the election campaign 2014. The purpose was to examine the difference in rhetorical strategies for the two parties. The methods used have been mainly qualitative text and picture analysis based on theory of semiotics and rhetoric fr
Equipped with Junot Díaz’s novel The Brief Wondrous Life of Oscar Wao (2007) and his collections of short stories Drown (1996) and This Is How You Lose Her (2012), this thesis interprets the fundamentals of migrant literature, studies Díaz’s tools of migrant depiction, and examines contemporary postcolonial and migrant discourse. This is performed in three integral segments of study. First, the un
In this paper, a corrugated plate heat exchanger in solar energy systems is used to investigate heat transfer and fluid flow characteristics of various nanofluids. By adding various nanoparticles (Al2O3-30 nm, SiC-40 nm, CuO-30 nm and Fe3O4-25 nm) into the base fluid, effects of nanofluid types and particle concentrations (0.05 wt.%, 0.1 wt.%, 0.5 wt.% and 1.0 wt.%) on the thermal performance of t
Genetic plant diversity is crucial to meet future challenges through plant adaptation to new biotic and abiotic conditions. To date, conservation strategy focuses on an ex situ (off-site) approach whereas the importance of in situ (in-site) conservation has been stressed to increase the public engagement and facilitate the gradual evolutionary adaptation of the material. This essay focuses on the
Our purpose with this paper was to examine the school and class situation in form nine from the pupils' own perspective, and their thoughts about ending comprehensive school. The main questions were: How do pupils in form nine describe the best vs. worst about school? How do pupils in form nine describe the relations in their class? How do pupils in form nine describe their own role/position i
Street children living in eastern Africa is a group of people who face more health problems than the general population. The purpose of this study was to examine the views of a group of eastern Ugandan health workers on the health of street children and how health care for street children should be carried out. The study was designed with snowball sampling using semi-structured interviews. The met
Bloggar som uttryckskanal har under de senaste åren blivit allt mer populära. Vad som vidare blivit tydligt är den bristande forskning om såväl bloggen som kommunikationskanal samt personligt varumärkesbyggande. I denna uppsats har vi studerat hur personligt varumärkesbyggande kommer till uttryck i personliga bloggar. Vi har genomfört kvalitativa intervjuer med såväl personliga bloggare som områdeBlogs as channel for expression has in recent years become increasingly popular. What is also becoming clear is the lack of research on both the blog as a communication channel, and personal branding. In this paper we have studied how personal branding is reflected in personal blogs. We conducted qualitative interviews with both personal bloggers and area skilled authors and consultants in order t
To accurately determine the efficiency and range of an electric vehicle, one must be able to estimate the rolling resistance of the car. This is currently done using standardized methods developed under laboratory settings, where transient aspects and effects of varying temperatures are excluded. Given the strong correlation between tyre temperatures and the rolling resistance, determining this te
The purpose of this paper was to examine how five persons who identify themselves as porn addicts view their addiction in terms of how the addiction have come about, what affective experiences they associate with the addiction, how it affects their relations to others, what makes them continue using pornography, what forms the addiction takes and how they live with their addiction today. Based on
This work presents a rule-based character-recognition system for the Korean script, Hangeul. An input raster image representing one Korean character (Hangeul syllable) is thinned down to a skeleton, and the individual lines extracted. The lines, along with information on how they are interconnected, are translated into a set of hierarchical graphs, which can be easily traversed and compared with a
