No full textIn a lifelong journey of self-conscious reevaluations the Swedish geographer Gunnar Olsson has pursued his core theme of human interaction in search of its geographical essences. Marked by a refusal to limit his geography to the study of visible things, Olsson has developed an original yet consistent cartography of how humans find their way into the unknown by relying on cultural maps which treats the invisible as if it were visible. What unfolds in his geography is an understanding of modern reason as a form of cartographical reason founded on a taken-for-granted geometric coordinate net of lines, points, and planes. Preceding a critique also of his own approach, he recognizes that this is also a reason which is becoming increasingly outdated, although it is likely to continue to haunt us as well as human geography.</p
Materialmodell för nylonfiberförstärkt gummimembran
No full textI detta projekt framtas en materialmodell, lämplig för ett anisotropisk
nylonfiberförstärkt gummimembran, varefter modellens parametrar
bestäms och verifieras. Gummimembranet används i en bromsaktuator
producerad av Haldex AB. Syftet med arbetet är att förenkla
och effektivisera framtagningen av framtida prototyper av bromsaktuatorn.
Målet med detta arbete är att med hjälp av en materialmodell
beskriva de mekaniska egenskaperna hos ett fiberförstärkt gummimembran.
Huvuddelarna av projektet är val av materialmodell, materialtestning,
modellkalibrering och verifiering av materialmodellen. En
variant av Holzapfel-Gasser-Ogdens materialmodell (HGO) som finns
implementerad i Ansys, ett beräkningsprogram för finita elementmetoden,
används i arbetet. Materialtestning utförs enligt ISO 527-4, en
standard för dragprover av fiberförstärkta polymerer. Modellkalibrering
utförs i Excel för att bestämma värdet på modellens parametrar
genom att anpassa kurvorna från materialmodellen till dragproverna.
Materialmodellen med dessa parametrar implementeras i Ansys, ett
beräkningsprogram som tillämpar finita element analys, som kan användas
för simulering av dragprov. Modellen verifieras till sist genom
simulering av bromsaktuatorn i Ansys. Vid jämförelse av simulering
och tester på material, uppvisar simuleringen av dragproverna god
överensstämmelse. Simuleringen av bromsaktuatorn uppvisar däremot
inte samma goda överensstämmelse med tester på komponent.In this bachelor thesis a material model is developed for an anisotropic
nylon fiber-reinforced rubber diaphragm, at which point the parameters
of the model are determined and verified. The diaphragm is used
in a brake actuator developed by Haldex AB. The purpose of this
project is to simplify and streamline the production of future brake
actuator prototypes. The goal is to describe the mechanical properties
of a fiber-reinforced rubber component using a material model.
The main parts of the project are choosing material model, material
testing, calibration and verification of the material model. A variant
of Holzapfel-Gasser-Ogden’s material model (HGO) is used in this
project. Material testing is done by using ISO 527-4, a standard for
uniaxial tensile tests for fiber reinforced polymers. Excel is used to
fit the material model to the test data, and thus find the parameters
for the material model. The material model with its parameters are
then implemented in Ansys, a mechanical engineering software that
uses finite element analysis, which can be used to simulate tensile
tests. Lastly, the material model is verified by simulation of the brake
actuator in Ansys. Comparing simulations with material data, the
simulations of the tensile tests are in good agreement. The simulation
of the brake actuator, however, doesn’t show as good of an agreement
with the test data

Preface to Diversity, Inclusion, Equity and the Threat to Academic Freedom
No full textThere can be no doubt that discrimination based on sex, race, ethnicity, religion or beliefs should not be tolerated in academia. Surprisingly, however, in recent years, policies of Diversity, Inclusion and Equity(DIE), officially introduced to counteract discrimination, have increasingly led to quite the opposite result: the exclusion of individuals who do not share a radical 'woke' ideology on identity politics (feminism, other gender activisms, critical race theory, etc.), and to the suppression of the academic freedom to discuss such dogmas. This subversion of academia ― disguised Trojan-horse style as universal human rights advocacy ― is unacceptable because academia must be politically neutral and protect freedom of speech, a cornerstone of professional scholarly activity without which universities as we know them will slowly but surely suffocate.
Our purpose here is to put together some particularly illustrative cases of such repression in a single book, testifying to a ubiquitous trend within western culture, irreducible to a few isolated complaints. The essays contained here illustrate the abuse of power, censorship and witch-hunts at many universities and research centres in the name of DIE.

De Ludo Globi or the Reason of the Sphere
No full textDe Ludo Globi or The Reason of the Sphere is about Gunnar Olsson’s
Geography. The argument is that the globe is a map with a different form. The
lines of my argument are drawn from Olsson’s two-tiered reason: “firstly, that
understanding by definition is an exercise in translation, secondly that every
translation involves transition from one language to another” (Olsson 2007: 82).
And this paper is exactly an exercise in transition from the language of Geography
to the silent language of friendship; but if it is easy “to know the meaning of what
I see and hear”, it is difficult “to find the proper expressions of my emotions" (Olsson, 2007
Is there any difference in practising rescuing service law and law of protection against accidents?
No full textAbstract Is there any difference in practising rescuing service law and law of protection against accidents? C-essay in jurisprudence vt 2007. Author: Martin Olsson Tutor: Stefan Olsson In the last seven years the society has been changing it’s thinking around security. Trough the disasters of the World trade centre in the United States and the natural catastrophe in Thailand. Today it’s very important to have a good reliable security. In Sweden we have made a change in the law regulation around security on field of rescuing. The rescuing service (1986:1102) law do no longer exist and it’s replaced by the law (2003:778) of protection against accident. The question is what this means, has this transformation been a positive change or the other way around. The purpose of this essay is to examine “if it is any difference in practising the rescuing law and law of protection against accident” through a case study. The conclusions is based on material from books, the work around the law and interviews of people working with the law on local, regional, central level. From this facts the essay came too the conclusions that the law of protection against accidents is interpret in an extensive way. The old law was interpreted in a restrictive way. This change has made the interpretation more diffuse than before, especially in the regional and the central level. On the local level it became a problem to work in an effective way. They got a heavier administrative work through the demand of a briefing from the individuals with a business where it’s a risk of a fire too start. These briefings were also very diffused formed for the individuals too understand the meaning of it. One positive effect was the direct aim on some objects with a big lack of standard and making them more effective faster then before. The new law made a different working mode for those who work as a supervisor. In the former law they measured how they organised themselves. Today they measure ability. This is positive way too deal with everything around accidents

Moduli of Elliptic Curves via Twisted Stable Maps
No full textAbramovich, Corti and Vistoli have studied modular compactifications of stacks of curves equipped with abelian level structures arising as substacks of the stack of twisted stable maps into the classifying stack of a finite group, provided the order of the group is invertible on the base scheme. Recently Abramovich, Olsson and Vistoli extended the notion of twisted stable maps to allow arbitrary base schemes, where the target is a tame stack, not necessarily Deligne-Mumford. In this dissertation, we use this extended notion of twisted stable maps to extend the results of Abramovich, Corti and Vistoli to the case of elliptic curves with level structures over arbitrary base schemes. We prove that we recover the compactified Katz-Mazur regular models, with a natural moduli interpretation in terms of level structures on Picard schemes of twisted curves. Additionally, we study the interactions of the different such moduli stacks contained in a stack of twisted stable maps in characteristics dividing the level
Jack Alive / Martin Dead : The Location of the "Author" in Jack London\u27s Martin Eden
No full textThis essay is an attempt to read Martin Eden, Jack Londonʼs autobiographical novel, in terms of the inextricable relationship between the author and the protagonist. Critics have often taken the unbalanced plot and the lack of ironic distance between narrator and character in Martin Eden as the technical weakness of London, but this paper argues that the achievement of this novel owes a great deal to the attachment of London to Martin. The unbalanced structure is a necessary product of the severe struggle of the author to kill his romantic alter ego. // Martin, who aspires to win Ruth Morse, tries to cross class boundaries by making a career of a writer. Even after realizing the emptiness of Ruth, who turns out to be nothing but a typical figure of the bourgeoisie, he somehow persists in loving her. The notion underlying here is that, for Martin, love, career and art are fundamentally inseparable. He objects to the aestheteʼs view of Brissenden on account of his separation of art from career. Martinʼs identity and life consist only in the triunity of love/career/art; the alternative is the repudiation of life. Thus, the unnatural delay of his disappointment in love can be regarded as Londonʼs strategy to set the suicide of Martin as the necessary consequence of the story. // By finishing the story and killing Martin, London finally detaches himself from Martin, reconstructs his self, and, unlike Martin, survives as a professional writer. In this sense, Martin Eden is a story about “writerʼs self-reconstruction.
