Användningen av Internet har ökat kraftigt de senaste åren och begreppet webbportal har blivit allt vanligare. Syftet med det här arbetet är att undersöka om det är en webbportals design som är det avgörande vid valet av webbportal eller om det är innehållet och tjänsterna. Kanske är det en kombination av design och tjänster som värdesätts högst.I detta arbete utförs en heuristisk utvärdering av ett antal bostadsförvaltningsportaler för att undersöka både eventuella användbarhetsproblem samt hur väl designade portalerna är. I arbetet görs även en enkätundersökning hos ett antal utvalda hyresgäster hos AB Skövdebostäder för att undersöka inställningen till designen av företagets webbplats samt dess innehåll och tjänster.Resultatet visar att webbportalers tjänster är viktigare än designen men att designen inte är helt oviktig. Några generella slutsatser kan dock inte dras av detta arbetes undersökningar eftersom både antalet medverkande portaler och hyresgäster är allt för få..

Erythropoiesis is a complex and carefully controlled process which is mainly regulated by erythropoietin. Using flow cytometry cells in a blood sample can be analyzed one by one. ADVIA 2120 using flow cytometry for analysis of red blood cells (RBC) and reticulocytes. Red blood cell distribution width (RDW) is a component of the RBC method. RDW indicates size variation on erythrocytes and is measured as a percentage of the mean cell volume (MCV). By measuring the RDW anemia can be divided into makrocytic, microcytic or normocytic. Reticulocytes refract light more strongly than red blood cells because they contain some cellular debris. The number of reticulocytes in the peripheral blood reflects erythropoiesis in the bone marrow. The purpose of this project was that by approved methods to establish reference ranges for the parameters, RDW and reticulocyte counts.The individuals who participated in the study, n=124, were considered healthy and had varying ethnicity. Reference subjects had not donated blood the last six months and participation in the study was voluntary.The statistic evaluation includes examination of distribution, and reference ranges for both men and women were established using the 2.5:t and 97.5:t percentiles. The calculated reference interval for RDW was between 12.0 ? 14.3% and the calculated reference interval for reticulocytes was between 38.0 ? 112.8 x109 cells/L. The results showed a significant difference between males and females for the parameter reticulocytes was seen. The difference indicates that different reference ranges should be established for men and women (p<0,0001). No significant difference between males and females were seen for RDW (p=0,74) indicating that the same reference ranges can be used for both men and women. .

Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.

Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.

This Master Thesis is a product development project that has been carried out in cooperation withSvea Teknik AB.

Introduction: Analysts worldwide valuates stocks and companies by using different valuation models. The models are used to calculate how much public company?s stocks are worth and to identify whether stocks are over- or undervalued.  Objective: The objective of this essay is to study which valuation models are mainly used by financial analysts in Swedish banks. The purpose is also to study how reliable these models are considered. Method: The empirical study is based on a qualitative approach through interviews with financial analysts. The study includes both primary data (interviews) and secondary data (literature, websites and scientific articles)Theory: The theory chapter includes methods of analysis (fundamental and technical analysis), Valuation models, components of valuation and an example of a valuation with the Discounted cash flow model. Empirical study: The study includes a qualitative research that consists of interviews with financial analysts.

Detta arbete består av designen av ett gränssnitt för webbplatsen whatismykidplaying.com. Designen var tänkt att ge hög användbarhet för målgruppen och testades av användare i ett think-aloud test. De fick testa och utvärdera hur väl gränssnittet fungerar och  deras feedback utvärderades och resultaten låg till grund för förslag på förändringar i gränssnittet, vissa som sedan blev implementerade. Studien har utgått från de olika stegen i en användarcentrerad utvecklingsmodell, analys - design - utvärdering - återkoppling, och en iteration har genomförts.Som utgångspunkt, för att öka användbarheten i webbplatsens gränssnitt, användes diverse regler och riktlinjer för hur användbarhet bäst kan uppnås, när designen gjordes. Hur väl dessa regler och riktlinjer fungerat tillsammans, i detta projekt och design, blev således en del i think-aloud testest utvärdering.

The study addresses the field of design as a profession and examines the views on strategic management in a design project among nine selected graphic designers. The graphic designers who participate in the study are permanently employed at design companies in Stockholm. The study has a qualitative approach and the method is based on face-to-face interviews. We have chosen to examine this subject due to the opinion among professionals that strategic management in the design industry has increased during the last decades. There is a belief that strategic management in some cases are used too extensively as a way for design companies to make more money.

When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.

This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.

The Mobile phone has contributed to massive changes in the way that human beings communicate with each other and is a part of society?s globalization. Opinions differ in the area of user interface where some feel that mobile phones exclude users such as senior citizens or users with an intellectual or a physical disability.Universal Design ??design for all?, is a vision that intends to bring about settings, products and services that suits as many people as possible irrespective of an individual?s needs and prospects. The criteria for ?design for all? are among other things flexibility, user friendliness, comprehensibility and a high tolerance for mistakes.The purpose of this essay was to investigate the mobile phones graphic user-interface from the theory of a universal design.

Construction projects are organized in different shapes and disturbances in the information flow in these processes can lead to problems, such as delays and/or a lower quality. Therefore, a well-functioning interaction between actors and a well thought out-communication at an early stage is of crucial importance. The main question is "How does the communication of decision and information flow in the building process and what barriers and opportunities can be observed?". This diploma work has been written with guidance from Bjerking AB and to answer this question, a collection of empirical data conducted via semi-structured interviews.

The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.
