This is my work about the subject taboo and impulse. It is an artistic studyinspired by the neuropsychological concerning impulsiveness. Because that?swhat it is; an artistic bachelor exam work, and not a scientific research. Icreated three costumes inspired by taboo and impulse.

Faskompenseringsutredning vid ett pappers och massabruk

SammanfattningRapporten innehåller en utredning om, hur och på vilket sätt, det är möjligt att minska det reaktiva effektuttaget vid Metsä Boards fabrik i Husum. Detta är inget problem i normalfallet, men om någon av fabrikens tre turbiner på grund av till exempel service inte är i drift så kan det reaktiva effektuttaget bli för stort enligt avtal med elnätsägaren. Om elnätsägarens gräns överskrids måste en straffavgift betalas per varje överskridet kVAr, vilket Metsä vill undvika. Fokus för arbetet ligger på fabrikens papperbruk eftersom detta är problemområdet.Efter genomgång av enlinjescheman och olika mätutrustningar som finns belägna i fabriken inses att det är mest lämpligt att kompensera i anslutning till bestrykningsmaskinen (BM1). Bestrykaren är den enda linjen på pappersbruket som inte har faskompenseringsutrustning.För att hålla sig inom nätägarens gräns beräknades att faskompensering med en kapacitet på 15 MVAr räcker.

Problem med att få besiktningsanmärkningar åtgärdade. Felaktiga inställningar och attityder fördyrar våra byggprojekt

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Matematiksvårigheter : En kvalitativ och kvantitativ studie om matematiksvårigheter.

We have done a qualitative and quantitative study about math problems on second­ary school students. The study is based on the diagnosis, treatment and training of teachers, about students who have math difficulties. The aim of this work is to obtain teachers ?perceptions about students? diagnosis, treatment / improvement and continuing education for students who have math difficulties. By having interviewed various teachers through surveys we have received answers to their concerns about the diagnosis, treatment and the importance of continuous training of teachers on students? mathematics difficulties.

Risk och krishantering : bevarandepolitik och normaliseringsproduktion

In this essay, Risk and crisis management Conservation policy and normalization production, I discuss how societies, communities and individuals are responsible for the handling of catastrophes and crises. Risk and vulnerability analyzes are parts of modern risk and crisis management. The purpose of these analyzes is to prepare people and organizations for any crises. For managing this it is necessary to comprehend, be able to change mindset in creating concrete tasks and inform others.The purpose of this essay is to analyze modern risk and crisis management by studying empirical material, such as interviews, observations and literature. My aim is to combine these materials and study how they cooperate.One of the findings in this essay is that risk and vulnerability analyzes are of great complexity. These analyzes require a discussion in order to identify the development of the society's crisis management system, as well as the continued support of the individuals that have a responsibility for preventing and preparing their organizations..

IKT och Pedagogik : En kvalitativ studie om datorbaserad undervisning och elevutveckling utifrån språklärares perspektiv

The purpose of this paper was to investigate the foremost teachers thinking of computers in teaching, how they work practically with computers as a tool, and if it is reflected in the students' school performance. To carry out this study, I used qualitative interviews as a method and I have interviewed four teachers where two works at the high school and two in upper secondary school. Both schools use computers in teaching as a supplementary tool for teaching materials. All teachers have similar ideas regarding what purpose one should use the computer and in which way, but the important thing is that the teachers and students receive an introductory course in how to use computers. Educators agree that this approach is and can promote students' language and knowledge regardless of the subject.My informants have come up with own methods that they use in the digital classroom including Skype, YouTube, Facebook and flippedclassroom where one can learn from other educators working.

Akustisk trädgårdskonst : att ge sonisk karaktär åt en plats

Ljud och trädgård är kanske inte det första par man tänker sig som gifta men de tus historia kan spåras längre tillbaka i tiden än man kan föreställa sig. När jag bestämde mig för att skriva min kandidatuppsats om akustisk trädgårdskonst trodde jag att ljudinstallationer i trädgårdar och parker var ett nytt fenomen. En helt ny värld öppnade sig framför mina ögon då jag insåg att så inte var fallet. Konstgjorda ljudkällor, såsom gyllene fåglar och vattenorglar, har kommit och gått genom tiderna medan naturliga ljud, såsom vind och fågelsång, bestått. När det kommer till vår egen tid är trädgårdsljud, även om moderna material och tankesätt används, en konstform som starkt präglas och inspireras av sin historia. Du kan skapa olika sorters ljudmiljöer i din trädgård beroende på vad du väljer att använda för material.

Kinetisk Keramik

Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..

Min pappa är negerkung : En kvalitativ studie av etniska stereotyper i filmatiseringarna om Pippi Långstrump

The purpose of this paper has been to examine various ethnic stereotypes in two Swedish film adaptations of Astrid Lindgren?s character Pippi Longstocking. I have used a semiotic content analysis and postcolonial theory to investigate: 1) how the ethnic groups are represented in the different materials, 2) if there is a hegemonic relationship between the foreign group and one?s own group, 3) whether there has been a "decolonization" during the twenty years that separate the two films. This study has shown that, in the 1949 adaptation, primarily Africans were produced in a negative light and as biologically inferior in relation to the whites.

The main theme in the interviews has been the characteristics and importance of play.

Läsinlärning och läsförståelse : Sju pedagogers erfararenheter i undervisningen med läsinlärning och läsförståelse

This thesis is based on qualitative text analyses of four works of fiction, used as teaching materials in the school subject of Swedish, from a queer theoretic perspective. The purpose of the study is to examine how sexual identities and expressions are being presented, as well as what positions are offered a reader, in relation to the heterosexual norm. Basis for this thesis are the schools fundamental values, which highlights the importance that intolerance be confronted through both knowledge and active measures, and the syllabus, which states that fiction should be viewed as a tool for identity development as well as an understanding of the outside world.The analyses reveals a distinct connection between the generally accepted heterosexual norm and a professed (or taken for granted) heterosexuality which is being carried out by the characters or the books as a whole. Out of the four titles only one disputes this norm, by offering a wide range of sexual identities and expressions. These expressions, however, are being invalidated ? through insufficient ability to relate to the norm ? or made invisible ? through an imagined heterosexuality which, by superiority over other expressions, excludes them..

Identifiering av avgo?rande faktorer fo?r optimal intern bygglogistik : En fallstudie av tre byggarbetsplatser

Unlike the manufacturing industry, the construction industry is always in motion. Each new construction project brings new opportunities, and it requires a new plan, new organisation, and new suppliers. All construction projects are very different from each other and in terms of a logistical perspective, this is very weak as it makes it difficult to get a flow in the production and to make flawless routines. The way the external and internal logistics are managed, can effect the final product in the time taken to produce it, the quality of the product and the profit made from it. When internal logistics are handled poorly, it could result in materials not being at the right place at the right time, or information not going through to the right person.
