Denna rapport beskriver optimering och analysering av Örtoftaverkets vatten till recipient i följande tre områden: • Processvattenreningen, fällning och flockning • Rökgaskondensatet, kvicksilverreduktion • Dagvattendammar, reningsgrad Processvattenreningens fällning och flockning var i behov av intrimning för att öka flockstorleken och –hållfastheten, och på så vis underlätta avskiljningen av meThis report describes the optimization and analysis of the outgoing water to recipient from the heat and power plant Örtoftaverket. The following three areas were investigated: • Process water purification, coagulation and flocculation • Flue gas condensate, mercury reduction • Stormwater ponds, degree of purification The coagulation and flocculation of the process waterwas in need of optimizatio

Current drawback in mass spectrometry-based lipidomics is the absence of a global and comprehensive lipid mass spectra library. Thus, the construction of such library was necessary, serving as a tool in different research projects. A liquid-liquid extraction (LLE) method for extraction of lipids from bovine serum and human blood plasma has been developed. Moreover, two different approaches were us

Hög energieffektivitet och god fordonsdynamik är två av de viktigaste fokusområdena för drivsystem i personbilar. En central komponent i BorgWarner:s produkter för momentöverföring är en lamellkoppling som regleras med hjälp av trycksatt olja från en hydraulisk axialkolvpump. Ett alternativ för att reducera energiförbrukningen och samtidigt förbättra pumpens prestanda är att variera pumpens deplacEnergy efficiency and good vehicle dynamics are two of the main focus areas for passenger car drive systems. A central component in BorgWarner’s torque transfer products is a multi-plate clutch which is actuated by pressurized oil from a hydraulic axial-piston pump. One way to reduce the energy consumption and improve the performance of the pump is to let the displacement of the pump vary dependin

Syftet med studien är att fördjupa förståelsen för chefers roll i innovationsprocesser inom unga kunskapsintensiva organisationer, med fokus på deras direkta och indirekta påverkan på innovation. Studien är utförd enligt kvalitativ forskningsstrategi, där insamlingen av data skedde genom intervjuer. Materialet analyserades sedan med hjälp av en innehållsanalys. Teorin grundas i aktuell forskning kThe purpose of this study is to deepen the understanding for the role of managers in innovation processes within young knowledge intense organizations, with focus on their direct and indirect influence. The study was conducted according to a qualitative research strategy and the collection of data was executed through interviews. A content analysis was used to analyse the data. The theoretical per

With the relative performance between accounting-based and option-based approaches for default prediction being a key subject in previous research, combined with criticism against the rating agencies’ timeliness in assigning credit ratings, surprisingly few attempts have been made to investigate the models’ usefulness in predicting corporate credit ratings. This thesis is the first to investigate

Globalization has developed workplaces that contain a mixture of people with different cultural backgrounds. Managing a culturally diverse workplace can be challenging and strategies for managing require constant improvements and adaptations in order to have a successful work environment. The purpose of this thesis is to highlight and gain a deeper understanding of how the power of cultural divers

Studiens resultat visar tecken på att revisionsbyråer inte har ett så stort ekonomiskt intresse i den lobbying de bedriver i samband med standardförändringar, som tidigare studier och teorier uttryckt. Istället har vi sett att revisionsbyråerna snarare agerar i samhällets intressen. Revisionsbyråerna är enligt vår studie mer benägna att undvika en ökad revisionsrisk, än att lobba för förändringar

Syftet med denna uppsats är att beskriva och analysera innehållet i bankers riskrapportering och huruvida en förändring har skett. Teorin innefattar en definition av riskbegreppet, samt vilka typer av risk en bank kan ställas inför. Det redogörs även för vad den institutionella teorin och ägarkostnadsteorin innebär. Utifrån teorierna presenteras slutligen Abrahams och Shrives (2014) modell om kval

Uppsatsens syfte är att genom intervjuer undersöka hur ekonomistudenter resonerar kring sin personliga, karriärorienterade identitetsskapande på sociala medier med utgångspunkt i teorier kring Consumer Culture Theory, symbolisk interaktionism och consumer empowerment. Studiens syfte uppnås med en kvalitativ metod samt ett fenomenologiskt och hermeneutiskt förhållningssätt. Primärdata har samlats i

Omegapoint AB acquired a TurtleBot 2 to explore one of the more popular open source robots on the market. Omegapoint wanted a web application, written specifically for them, to control the TurtleBot 2 for use in the Omegapoint office environment. One of the main things taken into consideration when designing the application was that it had to be runnable and usable not only on stationary computers

This thesis work was done in the SCAN COIN headquarters in Malmö, Sweden. In the work, we investigate the possibility to optimize the product SCAN COIN CashComplete POS. CashComplete is a closed system that makes it easy to pay with notes and coins and get the correct change back. To make CashComplete more attractive in a self-checkout environment the products price must be decreased. This work fo

This thesis is developed with collaboration and on behalf of Tetra Pak AB. The assignment was to create an internal system to manage site information and a license server to validate licenses. These systems are uniquely tailored for Tetra Pak’s requirements and the software they want to license. The internal system manages data that the sales division enters and creates text files from that site c

This bachelor thesis and project were done at Combitech AB in Helsingborg where the company had shown a previous interest in a rule engine solution for placement in the cloud. Part of the project was to identify an existing rule engine that could be further developed and implemented into a larger solution also adhering to any requirements presented by the target cloud system. Several candidates we

-A study focusing on the voltage fluctuations and symmetry at the one- and three-phase connections of photovoltaic systems.

One problem with the Swedish railways is the low reliability and punctuality. A distinction can be made between major and minor disorders, where minor disorders have a greater impact on overall punctuality because of its large numbers. One way to describe the large disorders are with punctuality dips and punctuality depressions, which are short-term and long-term variations in punctuality. This st

Prevas has in its customer contracts had a need for a simpler general manager for process recipes which send recipe parameters (eg rotational speed of a mixer or temperature in a furnace, etc.) to a Programmable Logic Controller. Software for this is available on the market but are either too complex or costly. To solve this problem a Windows service was developed. This report briefly describes ho

Målet med uppsatsen är att studera hur en välfungerande kallelsemall kan se ut samt att studera processen att ta fram en ny kallelse. Metoden som används är textanalys med kritisk diskursanalys som teoretisk ram. Två mallar för kallelse till cellprov har analyserats – en äldre version från region Stockholm Gotland samt en ny nationell cellprovskallelse. Analysen av språkhandlingar, attityder, närh

Producing electrical power with photovoltaic solar panels is very attractive as the sun constitutes an inexhaustible source of clean energy. However, in order to make it a better alternative to other energy sources, its drawbacks must be addressed. In particular, scientific research is very active to find technologies that increase the efficiency of the solar cells, or decrease their cost. Reducin
