Miljöberikning för grisarnas välbefinnande : Bökboxen - en prototyp för att motverka stereotypa beteenden hos grisar
The demand för Swedish pork meat is increasing every day. This leads to agricultural farming having to develop as an industry, with larger and more rationalised units to make the farming more effective and to raise the financial profit. The consequence of this is that it affects the animals when their surroundings become more industrial. The pig´s natural behaviour becomes restricted by the limitations of the facilities, which leads to them becoming understimulated. Helena Kummel, a teacher at Munkagård upper secondary school and also an educated animal inspector has developed a prototype that could possibly replace the pig´s natural rooting behaviour inside the barn. The porpuse of this report is to study "bökboxen" in the gilts´actual living enviroment, through qualitative- and quantitative analysis.
Animaliska restprodukter vid köttproduktion : Effektiv användning och livsmedelspotential
This master thesis aims to investigate and quantify the potential associated with increasing the usage of edible by-products as food for human consumption on the Swedish market. The main emphasis is on the Swedish production of offal and the obstacles that currently inhibit greater usage of these products as foods.The results indicate that the Swedish market for offal is limited. Only a small amount of the edible by-products that are produced in Sweden every year are consumed as foods and a considerable amount seem to be downgraded into animal feed or thrown away. The utilization of these products is restricted by economical, technical, legal, and cultural factors that all need to be taken into consideration. On the whole, large-scale slaughter plants seem to be more inclined to utilize these products effectively, as the profit from doing so increases proportionately to the produced volumes.
Förutsättningar att utforma stationsbatterier i vattenkraftverk med Li-jonteknik
In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.
Skärgårdsliv för rekreation : En undersökning av möjligheterna till vistelse i Stockholms Skärgård
AimThe aim of this study has been survey the possibilities for short-term stays in the Stockholm Archipelago for people without their own means of transport, own equipment and/or experience of outdoor life.To fulfil this aim, the following questions were formulated:? What communications are available to chalet parks in the Stockholm Archipelago?? What overnight accommodation is available in the chalet parks in the Stockholm Archipelago?? What activities can be pursued in the Stockholm Archipelago?? What is the financial cost of travelling to and staying in the Stockholm Archipelago for a week?MethodWe chose to use six interviews and three observations in order to gain as much insight as possible. Interviews were conducted with Claes Petterson at Waxholmsbolaget, a company that provides transport services in the Archipelago, and with managers for five chalet parks: Rolf Andersson for Finnhamn, Per Englund for Grinda, Arne Johansson for Rånö, Pär Hjärtström and Peter Hösöyen for Gålö and Anders Bedinger for Gålö and Nåttarö. The interviews were recorded in writing and on tape. Observations were carried out at three chalet parks, i.e.
Revision av gränsvärdena - En studie om hur svenska revisions- och redovisningsbyråer skulle påverkas av tillämpning av EU-direktivens maximala gränsvärden för revisionsundantag
Background: Currently Sweden has the possibility to like other EU countries raise the limits of statutory audit, but have chosen significantly lower limits. The reform was adopted in 2010 and only applies to smaller companies and there is great pressure for the limits to rise in future. This would enable Swedish companies to compete on equal terms in Europe. Aim: The aim of our study is to investigate the impact of the removal of the statutory audit for smaller companies from audit and accounting bureaus perspective and also the possible impact if the limits were to rise. Furthermore we want to explore how the supplies of other financial services have developed as a result of this.
Detektering av krypterade filer
In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.
Vikten av ett välskött arbetsklimat: En kvantitativ studie av arbetsklimatets påverkan på ekonomiskt resultat
The well-being of employees has become a key concept in the rhetoric of the company boards and business literature of today. There is however not much statistic evidence of a connection between economic results and the perceived working climate. This thesis sets out to investigate whether there is a positive correlation between economic results and working climate on a work group level. It also aims to study which specific working climate factors influence the results. In order to meet its purpose this thesis analyzes employee satisfaction questionnaire data and economic results from more than 300 work groups.

from
which
analyses
were
made
based
on
levels
of
community
and
individual
isolates.
Community
samples
were
used
for
attempts
for
characterization
of
resistance

Insatser för arbetslösa ungdomar i Glasgow och Malmö : ur ett socialpolitiskt perspektiv
The purpose of this study was to compare Glasgow/ Scotland and Malmö/ Sweden concerning their efforts towards youth unemployment, in sense of the social policy related to the organization. We have particularly concentrated on; the direct and indirect political strategies for young unemployed; what specific efforts that are provided on a local level; finding explanations to the design of these efforts and describing the development of youth unemployment and labour market- policies in each country. We have based our study on literature studies and six qualitative interviews conducted with representatives from different organizations and the municipality in Glasgow and Malmö. The outcome of our essay showed some differences in the political strategies. Scotland work closer to the employers and labour market compared to Sweden whose policy more promotes education.
Att utföra användarcentrerat arbete med små medel
Usability is a field within systems development which doesn?t get the attention it might deserve. Above all, it?s considered time consuming and expensive by many people in the industry. The current information regarding low-cost alternatives to achieve a more usable system seems to be almost non-existent.

Vision Nollenergihus : Energiförsörjning av passivhus med sol- och vindenergi
Climate change is the modern society?s common issue. The developed countries areconsuming more than what is sustainable, and the climate change due to the use offossil fuels can be seen clearly. EU has specified goals, in order to stop furtherdamage, which demand that every member state have to reduce its energyconsumption by 20 % before 2020 and 50 % before 2050, relative to 1995.The Swedish government uses a number of instruments to encourage reduction in theusage of energy, but every individual has to contribute to reach the goals.With increasing energy price the cost of living is going up. A lot of people are lookingfor ways to save energy and not be affected as much by the increasing price.Investments for insulation, replacement of windows and replacing old heating systemfor a new efficient heat pump is getting more and more common.This thesis is about investigating the possibilities in becoming independent from buyingenergy for households.
Användarundervisning på högskolebibliotek: en observationsstudie
This Masters thesis investigates user education at academic libraries. The increased demand on students to keep themselves updated in the information society of today urges libraries to develop their user education, concerning both content and teaching strategies. The aim of this study is to examine user education at academic libraries, and the approach of librarians in their teaching. The research questions address how librarians implement the user education and what they focus on. We also want to explore what differences and similarities there are between the user educations, and if anything could be further developed within them.
Bluetooth-implementation för Netbiter EC350
In industries today the demand for reading the state of industrial equipment and thus prevent machine breakdown, is increasing. The company HMS Industrial Networks AB has a product on the market, Netbiter EC350 that is used to read sensors and thus find out the condition of industrial equipment. By reporting scanned data to users through a cloud service, users can keep track of their equipment. When developing Netbiter EC350 a slot was made for a Bluetooth module to offer clients a wireless reading in future developments. In this project a prototype was made to show how this Bluetooth communication can be implemented. The goal of the project was to create a Bluetooth communication between a Bluetooth sensor and Netbiter EC350. A user interface was made to allow the user to read sensor values. The result of the project shows how a Bluetooth communication can be implemented to read sensors wireless and therefore it fulfills its purpose and goal.
Våga fråga: Faktorer som påverkar psykologisk trygghet i team
This thesis aims to further study the interpersonal risk taking within groups and thereby the importance of a climate promoting a reflective behavior. The increased demand in complexity and exposure towards teamwork leads to increased call for knowledge integration, which can be explained as the ability to integrate the collective knowledge within the group. We have therefor identified a need for better understanding what makes a group more effective. Key factors for self-estimated effective collaboration have been shown to be a group's reflective behavior and ability to coordinate the skills that each individual possesses. These factors are greatly affected by the psychological safety within the team.
