Tillverkningsanpassning av produkt för kostnadsreducering : Nya tillverkningsmetoder och verktygsparametrar
This thesis describes redesign and adaption of a products housing. In order to make it more economical to produce at a lower production volume. The thesis is based upon a prototype that a previous student developed for injection moulding. The goal is to find alternative manufacturing methods, but also to identify parameters that affect the cost of the injection moulding tool.The housing must be tough in order to protect the circuit board inside. But at the same time it must allow sound, light an electrical communication to pass through.

Specialpedagogers arbete i fo?rskolan med fokus pa? inkludering. Special educators work in preschool with focus on inclusion.
How do special educators work to include children with special needs in preschool? That was the question that our thesis proceeded from, and the purpose was to get an insight in the methods used by the special educators to achieve inclusion.
Our questions were:
? Is Swedish preschool a place for inclusion?
? How are special educators work organized and focused?
? Which experiences do special educators have working with children with special
needs in preschool, and what role do they mean that inclusion plays in this work?
Our procedure in this enquiry was to perform semi-structured interviews with 5 different special educators in two different cities.
Interpretation and analyis proceeded from three different theories: Urie Bronfenbrenner?s ecological systems theory, John Bowlby?s theory of attachment and Karsten Hundeide?s sociocultural theory. The result showed support for the idea of the Swedish preeschool as a place with many opportunities for inclusion. We have also seen how both money and political decisions has an impact on which possibilities the preschools receive to work with inclusion. In addition it became apparent that the methods used by special educators differed depending on both cities and districts.

The study included the whole process from the step of supplying therow materials to the last step in production functional test.In this thesis an investigation of how other companies are working with qualityassurance was conducted.
Economic impact of fertilizers and improved seeds among smallholder farming systems in Central and Western Kenya
In Kenya, many families subsist on agriculture and of the country's around 40 million residents 70% work in the agricultural sector. 50 % of the country's gross domestic production (GDP) comes from farming, and thus the country is largely dependent on income from this sector. Kenya's population has tripled in recent decades, which have led to that food availability is a growing problem.
To ensure food security, it is important that the return from crops increases. The aim of this study is to evaluate what impact the use of fertilizers and improved seeds has for farmer?s economic situation and income generation.
Vasastaden och gentrifieringsprocessen 1970-2010
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Erfarenheter av utedrift med köttdjur i Sverige och Kanada :
Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.
Liten vill bli stor - Effekter av Turkiets tullunionsbildande med EU
Turkey?s nearly fifty-year-old aspiration for admittance to the European Union took a crucial step forward with the signing of the Ankara agreement in 1996. The aim of this thesis is to examine the trade effects that evolve from the creation of a customs union. Our objective is to study how Turkey?s trade patterns adapted to the liberalized trade by examining the effects on resource allocation, specialization and welfare.
Kunskapssyn och behov av IKT-verktyg
In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.
Kritiska Prestations Indikatorer (KPI), Hur väl fungerar KPI:er som verksamhetsstyrning inom den producerande industrin?
The purpose of this thesis is to examine how key performance indicators are
being used as performance management tools within the production industry.
Specifically the purpose is to investigate how the KPI:s within the
telecommunications industry drives reusability regarding production test
systems.
This thesis will also highlight today?s cost models and suggest improvements of
the KPI and what new ones could be introduced.
A case study at Ericsson AB has been performed.
Jämförelse mellan renskötsel och betesbaserad fårskötsel
This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.
Doing Business in China - A Best-practice Model for Foreign Invested Small and Medium-sized Enterprises (SMEs)
Foreign invested SMEs have recently become increasingly interested in China. The enterprises are in this report categorized as second wave companies since they follow the footsteps of previous pioneers, of which mostly were larger companies. The ambitions of the SMEs are either to sell products on the ever expanding Chinese market or to utilize the potential of low cost production for global markets. The existing literature is fragmented and solely based on the experience of larger companies. We believe that SMEs are facing new and different challenges, and thus a new generic theoretical frame work is desirable.

Fånggrödor i Norra Östersjöns vattendistrikt
70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the
requirements for good ecological status. This is mostly due to eutrophication caused by a too
high deliverance of nutrients from agricultural land or effluents. Losses of particulate
phosphorus through water erosion contribute to a great extent to this eutrophication. In the
action plan for the water district cover crops are mentioned as a measure for reducing losses
of phosphorus from arable land. This paper reviews the possible effect of cover crops in the
water district and discusses what crop that would be most suitable.
Standardisering kontra flexibilitet : En fallstudie av utvecklingsprocesser
Process standardization is a topic that has generated a lot of research and literature. At first, the focus was on production; today processes are used in all different kind of business areas.The aim of this study has been to analyze how processes can be applied on development businesses and how IT systems affect the result of the process. To accomplish this, we have asked questions such as what standardization is in a development process? Why are the processes standardized? What difficulties can appear with standardization? And how the IT-systems affect the result of the process?To answer these questions, we have preformed a case study on Saab. Saab is a well know Swedish company who are working with a project called the GMS-project, where they develop processes to cover the whole company´s business areas.The literature gives the reader an understanding of processes and standardization.
