Geometry of the Prytz Planimeter
The Prytz planimeter is a simple example of a system governed by a
non-holonomic constraint. It is unique among planimeters in that it measures
something more subtle than area, combining the area, centroid and other moments
of the region being measured, with weights depending on the length of the
planimeter. As a tool for measuring area, it is most accurate for regions that
are small relative to its length.
The configuration space of the planimeter is a non-principal circle bundle
acted on by SU(1,1), (isom. to SL(2,R)). The motion of the planimeter is
realized as parallel translation for a connection on this bundle and for a
connection on a principal SU(1,1)-bundle. The holonomy group is SU(1,1). As a
consequence, the planimeter is an example of a system with a phase shift on the
circle that is not a simple rotation.
There is a qualitative difference in the holonomy when tracing large regions
as opposed to small ones. Generic elements of SU(1,1) act on S^1 with two fixed
points or with no fixed points. When tracing small regions, the holonomy acts
without fixed points. Menzin's conjecture states (roughly) that if a planimeter
of length L traces the boundary of a region with area A > pi L^2, then it
exhibits an asymptotic behavior and the holonomy acts with two fixed points,
one attracting and one repelling. This is obvious if the region is a disk, and
intuitively plausible if the region is convex and A >> pi L^2. A proof of this
conjecture is given for a special case, and the conjecture is shown to imply
the isoperimetric inequality.Comment: AmS-TeX, 23 pages, 12 figures in 2 *.gif files. To appear in Reports

Automated approaches for band gap mapping in STEM-EELS
Band gap variations in thin film structures, across grain boundaries, and in
embedded nanoparticles are of increasing interest in the materials science
community. As many common experimental techniques for measuring band gaps do
not have the spatial resolution needed to observe these variations directly,
probe-corrected Scanning Transmission Electron Microscope (STEM) with
monochromated Electron Energy-Loss Spectroscopy (EELS) is a promising method
for studying band gaps of such features. However, extraction of band gaps from
EELS data sets usually requires heavy user involvement, and makes the analysis
of large data sets challenging. Here we develop and present methods for
automated extraction of band gap maps from large STEM-EELS data sets with high
spatial resolution while preserving high accuracy and precision
Transition metal d-band occupancy in skutterudites studied by electron energy-loss spectroscopy
The transition-metal 3d occupancy of a series of thermoelectric skutterudites is investigated using electron energy-loss spectroscopy. We find that bonding causes an emptying of the 3d states in the binary skutterudites CoP3, CoAs3, CoSb3, and NiP3, while compared to the pure Fe the 3d occupancy in LaFe4P12 is significantly increased, consistent with the idea that each interstitial La atom (rattler) donates three electrons to compensate for missing valence electron of Fe as compared to Co. These experimental results are in agreement with previous models suggesting a predominantly covalent bonding between transition metal and pnictogen atoms in skutterudites, and provide evidence of charge transfer from La to the Fe-P complex in LaFe4P12

Identity, Culture and Literature: Hanif Kureishiâs The Buddha of Suburbia in Norwegian upper secondary classrooms
Denne avhandlingen undersÞker hvordan lesing av flerkulturelle litterÊre tekster, i motsetning til andre typer tekster, kan fremme interkulturell kompetanse i norsk videregÄende engelskfaglige klasserom. NÊrmere bestemt undersÞker den hvordan Hanif Kureishis Forstads Buddha (2017) kan brukes som kilde til Ä undervise i interkulturell kompetanse til norske elever. Den drÞfter ogsÄ de sentrale delene av LÊreplanen i engelsk som presentert i Fagfornyelsen fra 2020 (LK20), den nyeste revisjonen av den norske nasjonale lÊreplanen.
Avhandlingen benytter to forskningsmetoder: en litteraturgjennomgang, for Ă„ legge grunnlaget for temaene som tas opp i diskusjonen, og en litteratur analyse av Hanif Kureishis roman The Buddha of Suburbia (2017). Litteratur analysen fastsetter de relevante aspektene ved romanen for avhandlingen.
I avsluttende kapitler drÞfter avhandlingen de didaktiske fordelene ved Ä bruke flerkulturell litteratur i videregÄende opplÊring i Norge og vil forsÞke Ä svare pÄ problemstillingen. Det vil ogsÄ bli fremmet forslag til videre forskning pÄ dette temaet.
Denne avhandlingen er teoribasert og kan pĂ„ dette tidspunktet kun gi forslag til hvordan man kan arbeide med interkulturell kompetanse gjennom litteratur i norske klasserom.This thesis examines how reading multicultural literary texts, opposed to other types of texts, can foster intercultural competence in Norwegian upper secondary English subject classrooms. More specifically, it examines how Hanif Kureishiâs The Buddha of Suburbia (2017) can be used as a source for teaching intercultural competence to Norwegian learners. It also discusses the central parts of the subject English curriculum, as presented in Knowledge Promotion of 2020 (LK20), the newest revision of the Norwegian national curriculum.
The thesis utilizes two research methods: a literature review, to lay the groundwork for the topics that are being brought up in the discussion, and a close reading of Hanif Kureishiâs coming-of-age novel The Buddha of Suburbia (2017). The close reading establishes the relevant aspects of the novel for the thesis.
In the concluding chapters, the thesis discusses the didactic benefits of using multicultural literature in upper secondary education in Norway and will try to answer the research question. There will also be a suggestion for further research on this topic
This thesis is theory-based and at this point, it can only offer suggestions as to how to work with intercultural competence through literature in Norwegian classrooms
Promoting Data Journalism with Purpose-Made Systems: A case study of the benefits of purpose-made data journalism systems among Norwegian Data Journalists
The research project presented in this thesis is a case study investigating the usefulness of purpose-made data journalism systems. The study consists of two investigations, the first informal and exploratory, and the other more extensive and rigorous. The study features interviews with Norwegian data journalists based in the city of Bergen, which constitutes the main source of data. As part of the research, a prototype purpose-made data journalism system has been developed, based on preliminary findings from the exploratory investigation. The research carried out indicates that there is potential for developing computer systems designed to solve certain specific data journalism systems, concluding with a proposed application.Masteroppgave i informasjonsvitenskapINFO390MASV-IKTMASV-INF

Artistic expressions in landscape architecture : a example study on creativity and art to strengthen public space
Konsten har lÀnge varit viktig inom staden och landskapsarkitekturen. I
utvecklingen av stadsrummet prioriteras funktion och evidens över konstnÀrliga
och originella uttryck.
Syftet Àr att diskutera pÄ vilket sÀtt konst kan bidra till att stÀrka offentliga rum i
staden och vidare belysa olika skapandeprocesser som kan leda till konstnÀrliga
och originella uttryck i staden. Uppsatsen bygger pÄ en litteraturstudie och en
exempelstudie som ska skapa underlag för en nyanserad diskussion kring syftet.
Uppsatsens litteraturstudie diskuterar tre huvudÀmnen: hur konst och
konstbegreppet definierats genom historien, hur konsten pÄverkar mÀnniskan
och samhÀllet och om olika teorier och lagar som berör konstens plats i
landskapsarkitekturen och i det offentliga rummet. MĂ„let med uppsatsens
exempelstudie Àr att visa pÄ konstnÀrliga uttryck och originalitet inom
arkitekturen och landskapskonsten och sedan diskutera och peka pÄ vad
landskapsarkitekter kan lÀra sig av detta i gestaltandet av offentliga miljöer.
Genom att tÀnja pÄ grÀnserna inom respektive yrke och viljan att skapa
identitetstarka platser visar personerna hur offentliga rum kan stÀrkas. Det finns
mycket landskapsarkitekter kan ta lÀrdom av frÄn arkitekter och
landskapskonstnÀrer för att gestalta konstnÀrliga miljöer och skapa originella
uttryck.Art has long been important in urban and landscape architecture. In the
development of urban space, function and evidence are prioritized over artistic
and original expression. The aim is to discuss how art can contribute to
strengthening public spaces in the city and furthermore highlight different
creative processes that can lead to artistic and original expressions in the city.
The essay is based on a literature study and an example study that will create a
basis for a nuanced discussion of the purpose. The literature study discusses
three main topics: how the concept of art has been defined throughout history,
how art affects people and society, and various theories and laws that affect art's
place in landscape architecture and public space. The goal of the essay's example
study is to show artistic expression and originality in architecture and landscape
art and then discuss and point out what landscape architects can learn from this
in their design of public environments. By pushing the boundaries of their
respective professions and the desire to create places with a strong identity, they
show how public spaces can be strengthened. There is much that landscape
architects can learn from architects and landscape artists to design artistic
environments and create original expressions
