Utvärdering av Naturvårdsverkets bedömningsgrunder för makrofyter i sjöar

According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.

Faktorer som påverkar datakvaliteten hos affärs- och DW-system - En fallstudie från en högteknologisk industri

This thesis aims to examine how the quality of data that is entered into and retrieved from a corporate group's ERP and Data Warehouse systems can be improved. The corporate group has already taken several measures that will improve the quality of data. For instance the corporate group has updated and merged the previous ERP systems into one. At the same time the corporate group adjusted the settings in the updated ERP system, so that it will be harder to register incorrect data in the ERP system. With regards to the processes and routines, the studied department has efficient written routines and processes.

Solvärme för en skola i Lerum. Studier av olika systemalternativ.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Kvalitetskontroll av utskrifter från Kodak Approval XP4

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.

Älgarås avloppsreningsverk- studie och metodisk felsökning av en biobädds BOD-rening

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Validering av metoder för analys av Cu, Fe och Na i processvatten med AAS-grafitugn

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

Tjänstekvalitet för pensionssparande : En studie om vilka faktorer som påverkar den upplevda tjänstekvaliteten för pensionssparande

Our purpose of this paper is to seek an understanding of which service quality factors that affects customers in their decision making progress regarding purchasing financial services such as pension products. We also seek to evaluate the different service quality factors by compare their relative strength against each other. The study aim to investigate if there are any connections between customer behavior variables such as gender, age and income in comparison to these service quality factors related to pension products.The findings aim to help a small financial institute such as our case company Plain Capital to understand how their customers experience service quality regarding pension products.In order to find empirical results we conducted a qualitative research as well a quantitative research. The qualitative research employed both a focus group interview with pension savers and an interview with our case company Plain Capital. We were able to identify the service quality factors for pension?s products with help from the focus group interview.

Xlight-Retro : En lampa för offentliga inomhusmiljöer

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

Vem bestämmer över kvaliteten? : Bibliotekariers privata och professionella syn på kvalitativ skönlitteratur

With an increased empowerment of the users, and a dependence on outside critics, one wonders what kind of role the librarians have in a context where qualitative literature is discussed. The aim of this study is to examine the relationship between librarians private and professional views on qualitative fiction, in order to be able to discuss their role as quality intermediaries in a user oriented context.The method used, is the qualitative, semistructured interview. This author interviewed seven librarians from three different libraries in Sweden. The theoretical emphasis partly relies on the ten words of qualitative value that Inger Elam and Bengt Brülde discusses in their respective texts, partly on David Garvins quality assessment theory, which defines several quality categories divided between an absolute and a relative quality view.Through the comparison between the private and the professional quality view, examined with the two theoretical approaches, the analysis of the interview material shows that there lies a complexity in the librarians professional role. On the one hand, they are dependent of both the users and the critics judgements about the qualitative aspect in the work with purchasing new literature to the library.
