Fastighetsunderhåll : Arbete med underhållsplaner i stora fastighetsbolag
Background: The standard of living should be the same for everyone, whether the apartment is placed in an old or new building. The residential properties that were built from 1965 until 1974 is now beginning to become old and in need of restoration. The financial crisis during the nineties contributed to the lack of maintenance on the buildings in Sweden. As the public buildings gets older more and more defects occurs. The coordination and maintenance will therefore have a more significant role in the housing company ?s work.The increasing interest about how old a building can be, attract much attention.
Kvävestatus och risk för nitrifikation i två avverkade skogsområden i Halland
Nitrogen deposition leads to environmental damage in areas where the nitrogen deposition is high. Southwest Sweden receives an annual nitrogen deposition of up to 20 kg N/ha. Nitrogen that is not assimilated by the vegetation is accumulated in the soil, which may lead to nitrogen saturation and an elevated risk of nitrogen leaching. Nitrogen leaching from forest areas in southern Sweden has proven to be higher than from agricultural areas, which have been thought to be the main contributors to elevated nitrogen levels in rivers and lakes. The amount of nitrogen that leaches depends on the fraction of the total nitrogen in the soil that consists of nitrate, since nitrate is easily transported through the soil.
Ledarskap inom ramen för ett systemutvecklingsprojekt - fokus på en arbetsprocess med stöd i Vattenfallsmodellen
Many research reports mention the fact that a huge number of all system
development projects never reach a successful ending; with other words never
fulfil formulated goals. By identifying and forming success factors (and in
some aspect risk factors) that the project manager in practice can use, this
study may be seen as a step in the direction towards minimising the high number
of failed system development projects.
The purpose of this research report is to investigate how a system development
project, where the development process is based on a specific development or
process model (in this case the Waterfall model), can and should be driven. I
aim to clarify what is demanded of a project leader for the specific
development process and give an account for which eventual leadership qualities
that can be well suited for given situation in relation to the need for
technical competence.
Among other things the project manager should inspire confidence, drive, be a
decision maker, engage and own some form of basic knowledge in the field of
system development.
Bok- och grankonkurrens i Sydsverige - markegenskaper och naturlig föryngring :
In southern Sweden, beech (Fagus silvatica) and spruce (Picea abies) are two species with similar demands on soil properties. With increased global warming and high acid deposition the future may bring larger areas were the two species are overlapping, competing for the same soil. The aim of this study was to compare spruce and beech concerning distribution, cultivation and soil properties. From available data comparisons were made between spruce and beech forests in Sweden. Soil analyses were made on samples from beech forest in southern Sweden, with and without natural regeneration of spruce.
Betalningsmedel & dess risker
Today you can pay in many different ways. You can for instance use cash, credit cards, internet and now even with your mobile phone. Today we can also see new types of technical payment solutions being developed, such as Near Field Communication (NFC), mobile banking or through the use of QR-codes. We have today many different payment methods; therefore it?s interesting to see which payment method people prefer the most.
Mobilt community - Bygga själv eller hjälpa till? : Kommersialisering av en plattform för användardriven karttjänst i mobiltelefoner
Mobile Arts have a technical platform for handling maps and community-featured Points of Interest in cellular phones, where the users themselves can share locations with other users either in groups or public. Development of the platform regarding network communication has been included in this paper. The work evaluates different feasible business models regarding packaging the platform as a commercial application and also faces issues users have when using the product. Even if users found maps and POI interesting and cool in cellulars, the technical difficulties and lack of product focus during beta testing, were present. Therefore, the writers recommendation is more development of the platform and using a business model where Mobile Arts deliver to existing communities.
GRÖNYTEFAKTOR I ETT NYTT PERSPEKTIV - Går ekosystemtjänster att mäta med fjärranalys?
Due to an increased population in cities the need of densification of cities increases. This means that the amount of ecological elements in the city is at risk of decreasing. Ecological services contribute to the city?s climate by softening the negative impacts that densification of cities means. Thus increases the will and ambition in city planning in to preserve greenery.This is an interdisciplinary thesis within the subject of geography that studies Biotope Area Factor (BAF), a planning tool that is used in city planning with the purpose of compensating for lost ecological services associated with new housing estate.
Mätningar av statiska och dynamiska egenskaper för bakaxel.
To design new and high tech products the engineers rely more and more on computer based simulations to investigate the properties and behavior for a component or system.To verify these computer based simulations the dynamic properties for the components of the drivetrain needs to be verified. Therefore measurements of the stiffness and vibrations for the rear axle has been performed. This report show how the measurements has been implemented and evaluated, along with some interesting results for the rear axles properties.The static stiffness for the drive shaft along with the axle-gear has been determined. It is found that the stiffness for the whole rear axle is near the stiffness for the drive shaft, which means that the drive shaft becomes the dominant component of the system and affects the rear axle stiffness the most. The measured stiffness of the driveshaft is close to its theoretical stiffness.The stiffness for solely the hypoid-gear have been calculated using the stiffness for the rear axle and driveshaft, and thus has a range for the stiffness of the hypoid gear been determined.The backlash for the whole rear axle and for some individual components has been determined, where the backlash between pinion and crown-wheel has negligible impact on the total backlash.Measurements of the crown-wheel and pinion movements have been conducted, where the direction of movement is consistent with the theoretical direction of the forces.The vibration measurements show that the vibrations are more severe at certain rotational speeds.

Mutual Benefits were also partners in the project.The project was carried out by us in cooperation with Bachelor of Science in Innovation Engineeringstudents Malin Albertsson and Victoria Hedman at Halmstad university. The aid consists of a mobile phoneand a number of tags.
Busig eller flamsig : En studie av genus i bilderböcker
The aim of this thesis is to analyze children?s picture books regarding whether and in what form gender stereotypes can be seen in these. The purpose is also to evaluate whether the findings correlate to the different regulatory documents libraries have to abide to. The study comprises five books, who are part of a selection of books especially chosen by Uppsala City Library to be used by primary school children aged 6-9. The method used is the study of text as well as illustrations, as the theory of this thesis is that the two cannot be separated, but has to be seen a unit. Other theories used in the analysis include Nikolajeva?s schedule of male/female properties and theories on gender. The result of the study shows that gender stereotypes are in majority regarding the characters in the books, but that the opposite also exists.
APS - Akustiskt positioneringssystem
The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

Estimering av GPS pålitlighet och GPS/INS fusion
The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning. An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.
IAS 40- värdering till verkligt värde : En studie av hur värderingsresultatet av förvaltningsfastigheter skiljer sig beroende på val av intern eller extern värdering
Swedish listed property companies report their investment properties under the standard IAS 40 that gives the opportunity to value investment properties to either historical cost or to fair value model. One problem with the fair value model is that there is no observable market price since the real estate market is far from complete which means that the price of the asset is hard to determine because of the limited information.IAS 40 gives companies the opportunity to choose between internal or external valuation and this study aims to show how the property companies? values appeared between the years 2007-2011. From the result we will study if there could be a difference in the outcome depending on if the company chose either internal or external valuation.To investigate this we observe all Swedish real estate companies listed on OMX Nordic Stockholm and their financial reports during this period of time and complement this information by interviewing people working with these matters in the property companies. The methodology for the study is therefore partly quantitative and partly qualitative since we collect data both from financial reports and from interviews.
Gnosjöandans barn och deras framtidsvisioner : En studie gjord på Entekprogrammet i Gnosjö
The aim of this thesis is to study and analyze a village in the southern of Sweden called Gnosjö, which is famous for a special spirit of industrial success and entrepreneurship. Gnosjö has been successful and famous for many years but is now standing in front of several threats, like a growing number of out moving inhabitants, a low standard of education and difficulties for women to make carrier. Trying to reduce the threat of young inhabitants moving out, a new education program started three years ago with the purpose to make young students to be more interested in the technical development of the industry and make them stay in the district and hopefully be entrepreneurs.The research questions are; which consequences does ?Entekprogrammet? and the background of the students have on the students view on the spirit of Gnosjö, carrier in the local industries and wish of staying or moving from Gnosjö. Furthermore, I want to see if there are any differences between the girls and the boys, does sex have an influence on the view at the future? The study is made by qualitative and quantitative method.
