Kilhus i plast : Omläggning av stålprodukt till produkt i plast
AbstractOur bachelor degree thesis was carried out in collaboration with Ivar Petterssons Järnmanufaktur AB in Smålandsstenar. We were asked to replace their wedge housing, used to fasten the wires to the power lines, with a similar structure in a plastic material. The idea for this project started with Ivar Petterssons Järnmanufaktur AB having problems with the casting quality that forced them to perform expensive tests on each of the wedge houses to ensure the quality. They are currently produced in China which is also a major drawback because it requires expensive long delivery times.The method we used is Fredy Olsson's Princip- and Primärkonstuktion (1995). We have consistently been in the project on so-called "broad front", which means that you create several sketches, ideas and changes in parallel, and then evaluates all.
?Barnets bästa i första rummet? : Om diskurser och språklig praktik i diskussionsprogrammet
Childhood as a social category is under strucural redefinition. In this thesis the child and childhood are understood as socially constructed phenomenons. Focus is laid upon the construction of the concept ?in the best interest of the child? wich in The UN Convention on the Rights of the Child is defined as beeing the foremost important view to take into account when decisions wich affect children are made. As the thesis shows, a concrete and universall view of the best interest of the child is lacking in practice and would in many cases be unfortunate.

Hardware-in-the-Loop simulering av motorservon på ett inbyggt system
This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.
Motgångens möjligheter : en studie av ungdomars upplevelse av häktessituationen
The purpose of this study is to look into how detained swedish juveniles, in the ages between 15 an 20, experience time in custody.

-Inget rop på hjälp : En narrativstudie om självdestruktivt beteende
Studien handlar om självskadebeteende. Syftet med undersökningen var att få reda på vilka yttre faktorer som påverkade tre unga tjejer att börja skada sig själva. Forskningen på området anser att personer börjar skada sig själva pågrund av sexuella övergrepp i ung ålder, men det framgår tydligt i resultatet att sexuella övergrepp i detta fall inte påverkade tjejerna i studien. Till grund för tjejernas destruktiva beteende ligger traumatiska händelser i deras uppväxt både i lågstadieålder samt högstadieålder.Metoden som användes i studien var semistrukturerade intervjuer eftersom intervjuaren då kan rikta sin fulla uppmärksamhet mot respondenten.Resultatet är utformat på ett narrativt sätt vilket gjorde att resultatet kunde presenteras i berättelseform. I resultatet framkom vilka yttre påverkansfaktorer som påverkade tjejerna att börja skada sig, som till exempel föräldrars skilsmässa, eller plötslig död i deras nära omgivning..
Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation
Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.

Konstf?rst?relse/F?rst?relsekonster: En unders?kning av konstruktiv ikonoklasm som konstn?rlig process
Building on the concept of constructive iconoclasm as a creational force of iconicity, this thesis examines how the contemporary iconoclastic discourse is related to artistic process.
Studies have shown that the performative act of destroying art that is an historical phenomenon is highly present within the contemporary art discourse today. Due to the many dimensions of contemporary art, the ways in which iconoclastic deeds appear may differ from the historical narrative. While iconoclasm and iconicity are being reciprocal processes that can only exist in relation to each other and their context, there are signs that the destructive act itself is being recontextualized by contemporary artists. Guided by the framework of Norman Fairclough?s critical discourse analysis, the thesis examines the processes of conceptual and constructive art destruction by analyzing the discourses of two case studies situated in the contemporary art market.

Traditionell ekologisk kunskap i en framtid med lokala, självförsörjande och urbana samhällen
Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..
Miljöekonomiska analyser av smog och luftföroreningsproblemen i Kina
Rapid economic development and urbanization has led to an improved standard of living for the Chinese people. Meanwhile, a series of environmental problems have also appeared and smog, in particular, has caused the Chinese people to realize how serious the situation is. Smog has seriously affected normal economic activities and people's everyday lives, resulting in financial losses, increased mortality and disease. How to handle the smog becomes particularly important. The purpose of this study is to describe and discuss the underlying causes of two sources of pollution, particulate matter and sulfur dioxide, as well as what drives individuals' and firms' environmentally destructive behavior.
