The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

This thesis analyses the prerequisites, profitability and competitiveness of eucalyptus plantation on the Iberian Peninsula and in Brazil. The thesis has a macro perspective and analyses a typical hectare of eucalyptus in each studied region. A survey methodology was used as a strategy to cover a broad perspective using expert respondents. The regions studied on the Iberian Peninsula were the ones found suitable for eucalyptus plantations from an economic point of view. The studied regions were Huelva in the South West of Spain, Galicia in the North West of Spain and Portugal.

In Sweden, reduced tillage usually means non-inversion tillage, where primary tillage is carried out using chisel ploughs or disc implements. Primary tillage method is mainly determined by the desired soil loosening and the handling of soil residues. The effect of tillage depth was studied in field experiments in Skåne, Väderstad, Uppsala, Örebro och Västerås in different crops; spring oilseed rape, spring wheat, winter wheat and spring barley.The experiments generally had a randomized block design with the treatments mouldboard ploughing, deep chisel ploughing and shallow chisel ploughing, in some cases also shallow discing and no-tillage. In the experiments the following parameters were determined: seedbed properties, saturated hydraulic conductivity, penetration resistance, number of emerged plants and crop yield (all parameters were not determined in all experiments. Root growth and draught requirement were determined in two separate studies. There were no significant differences between tillage depths in non-inversion tillage in seedbed properties, plant emergence or root development.

Crop efficiency in utilizing available nutrients is an important factor in increasing produc-tivity and reducing the environmental impact of agriculture. Nitrogen is the nutrient that plants need in the largest quantity and wheat, along with maize and rice, is the world's most cultivated crop. In this work, the Nitrogen Use Efficiency, NUE, during the major growth period, HTP, of twelve different spring wheat varieties, were examined. The NUE was calculated as the product of uptake efficiency of nitrogen, UN, and the conversion effi-ciency of nitrogen to biomass, EN. The purpose of this work was to find if there are varietal differences in NUE and its components among the twelve varieties and to link a high NUE to specific characteristics of the varieties.

During a fire large amounts of particles and unhealthy agents occur.  Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.

Examensarbetet diskuterar behovet av ett stödsystem för lärare vid undervisning och tar upp olika aspekter utifrån lärarnas arbetssituation. Som en del av denna diskussion finns en implementation av ett system i form av en Androidapplikation.Applikationen ger lärarna möjlighet till ett stödsystem med olika användningsområde som närvarokontroll, anmärkningsmöjligheter om förseningar och stök under lektionstid, verktyg för att anteckna elevarbete och motivera betyg direkt på plats.Stor vikt har lagts på att göra applikationen lättanvänd och användarvänlig och därför har tester med användare varit en stor del under utvecklingen..

Detta har genomfo?rts genom dokumentation av designproceduren under alla dess olika moment, och sedan genom en utva?rdering och ja?mfo?relse av designprototypen gentemot dagens befintliga hemsida.

Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

Today, Ericsson Microwave Systems (EMW) uses non-graphical user interfaces in some of their Ada95 applications. EMW wishes to develope a more easy-to-use and platform independent graphical user interface (GUI) for their applications. To meet these requirements EMW has chosen to evaluate Java in GUI development with Ada95. To make it possible for the Java GUI to communicate with the Ada95 application, some kind of standardized interface is required. CORBA is a specification of such an interface.

This report presents the preliminary study and work for the development of a site structure for the upcoming reengineering of inter-tool Infopunkt. The report describes how I have conducted a study regarding the current inter-tool information center and its development potential. Thereafter compiling the information to develop a comprehensive design approach to create a sitemap. The sitemap illustrates a new updated page structure for Infopunkt and was the primary goal of the thesis. The sitemap I have developed will form the basis for the agency that will later on develop the new updated version of Infopunkt..

Användbarhet är idag en del av människa-dator interaktion som bl.a. Södertörns högskola satsar på att lära ut. Syftet med denna undersökning är att belysa användbarheten på Södertörns högskolas hemsida. För att definiera användbarhet används den internationella standarden för användbarhet (ISO 9241-11, 1998) samt människa-dator interaktionsforskaren Jacob Nielsens definition av användbarhet. Detta har genomförts genom en observationsstudie med fem användare.

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.
