Påverkad strukturerad produktion produktiviteten? : Analys av mätningar från byggbranschen
The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.
GRÄNSSNITTET OCH ANVÄNDARNA En undersökning av två gränssnitt mot en bibliotekskatalog.
The scope of this master´s thesis is the issue of usability in relation to interface design,in particular the interface of a university library´s online public accessed catalogue, orOPAC. Since the OPAC can be seen as the library´s ?shop window? to the world, it isof great importance that the interface to the OPAC can be used by patrons witheffectiveness, efficiency and satisfaction.The master´s thesis is based on a qualitative study performed at Karolinska InstitutetsUniversity library, and contains both a usability evaluation and an interview study. Twointerfaces were evaluated: a standard web interface provided by the system supplier, andan interface developed in-house by Karolinska Institutet´s systems department. The twointerfaces are both connected to the same online library catalogue, thus making possiblea comparative study..

RFID:s effekter inom logistik
Modeprodukter har en mycket kort livslängd och modebranschen förändras snabbt. Tiden är därför essentiell och utgör en betydelsefull konkurrensfaktor. Genom att reducera tid i försörjningskedjan kan ett företag vinna marknadsandelar samt höja sin lönsamhet. RFID är en teknik som kan användas för att reducera tid samt förbättra logistiska processer i försörjningskedjor. Trots att denna teknik har börjat spridas, används den generellt inte hos svenska modeföretag.

Energikartläggningen är baserad på ett verkligt objekt vilket är en förskola i norra Gävle. Denna skola förvaltas av Gavlefastigheter.I Sverige går cirka 40 % av energianvändningen till bostäder och service. Därför finns det stora mängder energi att spara inom denna sektor.
Volatilitet och effektivitet på aktiemarknaden -Har risken i enskilda aktier ökat?
I denna uppsats diskuteras sambandet mellan risk, marknadseffektivitet och volatilitet. En studie görs för att se om volatiliteten (kursrörligheten) har ökat i enskilda aktier under tidsperioden 1988-1999. Vidare behandlas vilka faktorer som kan ge upphov till volatilitetsförändringar, vilka konsekvenser en förändrad volatilitet får för olika typer av investerare samt om utvecklingen är förenlig med EMH (den effektiva marknadshypotesen).Studier av volatilitet är intressanta p g a den risk som uppstår för olika marknadsaktörer vid en ökad volatilitet. Uppstår felvärderingar på aktiemarknaden finns även risk för att kapital fördelas på ett sätt som inte är optimalt. I stora drag kan man definiera begreppet volatilitet som ett mått på hur stor osäkerheten är inför den framtida kursutvecklingen för en aktie.
Nätverksdemokrati -vad bör, är, kan den vara
The main objective of the essay is to define the meaning of the termgovernance network on the basis of democratic values ? both normative andimperial - with the aim to analyse the prospects to develop an effective anddemocratic governance. Democratic values as well as civil participation,enlightenment, responsibility and approachability are discussed, but also moreeffectivness orientated values.It is clear from the presentation how normative and democracy models putdifferent values in focus, with the consequence that other values are played downor pushed aside. Compared to imperial research in partnership ? by definition atype of network arrangement - and with a starting point in democracy andefficiency, the networks are discussed as political formation.In what sense can the actual existing network arrangements meet and fulfil thedefined political values? As no straight forward answer exists, there is an ongoingconflict between the political demand for slowness and the effectiveness demandfor flexibility and mobility..
Avskiljning av uran från dricksvatten med reaktiva filter :
Water is our most important provision and its quality is above all dependent on the
geological conditions in the area from where it is extracted. Due to geological
properties there are certain areas with an elevated risk of high uranium levels in the
ground water, which in turn constitutes a risk for human health. Consumption of water
that contains a high concentration of uranium implies a health risk due to the chemical
characteristics of uranium. Livsmedelsverket (The National Food Administration) and
Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that
precautionary measures should be taken when the uranium concentration in ground
water exceeds 15 micrograms per litre. In particular, drinking water collected from
wells in areas with uranium-rich bedrock may have a harmfully high level of uranium.
One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden,
contains water that exceeds the guideline of 15 micrograms per litre.
One interesting technique for removing uranium from drinking water is adsorption to
reactive filter materials.
Att balansera Management Control Systems - En fallstudie av ett litet svenskt IT-företag
This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.
V?RMEAKTIVERADE TISSUES P? TRANSPARENT PAPPER En j?mf?rande studie vid revlagning
Works on transparent paper, also commonly known as tracing paper, have been described as ephemeral or temporary working documents and they usually number large quantities in archival and museum collections. They have therefore previously been considered of lower priority and can be found in poor condition due to a lack of treatment or suitable storage prospects. In addition, transparent paper can be very sensitive to moisture and reacts by deformation or loss of transparency. Due to the volume of these works and the necessity of treatment, there is a call for simple and efficient conservation methods. A common solution in archives for the treatment of water-sensitive works on paper has been the use of heat-activated tissues as they can be applied without the introduction of solvents.
There is little published about the use of heat-activated tissues on transparent paper and is mentioned only briefly in existing literature.
Skötsam
The project has been performed in a close collaboration with Hörsam who works in the field of hearing technology. In a first meeting with the company, the Project group was showed a few existing storage boxes for hearing aids. The company thought they were unnecessarily large with plenty of unused space and wanted a new, smarter solution to be developed.The project began with user studies in which audiologists, maintenance technicians, future users and others were interviewed. The purpose was to obtain their views on today's storage boxes and to find out how well the users maintained their hearing aids. It proved to be a large lack of knowledge regarding the management of hearing aids within the users.
Användning av IT som resurs i sjukvården : En studie om interoperabilitet i vårdens eHälsosystem
Today significant resources are provided to improve the digital work environment within the Swedish healthcare to create efficiency, good work environment and patient safety. Despite this, major flaws are shown by the lack of communication between the eHealthcare systems. This becomes a stress factor among healthcare professionals because of increased administration and decreased physical contact with patients. The purpose of this study is to create a understanding of the concept of interoperability at different levels in the eHealthcare systems. This has been conducted through a qualitative interview study at a healthcare center where the respondents have been describing their digital work environment and the way it works today.
Utvärdering av energiberäkningsprogram : Att användas i tidigt planeringsstadium för byggnader
The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building?s physical characteristics for reliable energy analysis.
