Agila metoder ? en kartläggning av teori och praktik

In recent years, agile software development methods have become increasingly popular throughout the world. Today there are a number of different agile methods and they all rest on the Agile Manifesto that was formulated in 2001 as a reaction to the traditional software processes.The aim of this thesis is to make a survey of some of the agile methods used today and to see how they are being used in practice. It consists of two parts: a literature study and an interview study with people working in the software business. First, a definition of agile methods is proposed and a number of different agile methods are described. Second, the interviews are being analysed with special focus on communication, collaboration, expectations and results.

ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor

A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

Diskonteringsräntan påverkar graden av miljöpolitiska styrmedel : En studie om koldioxidskattens påverkan på koldioxidutsläppen

This qualitative study involves the implementation of Lean and Kaizen methods in a Swedish service industry. Lean philosophy is based on a method to achieve more with less. In practical terms this means that the use of an organization's resources is improved. The origin of Lean is the Toyota Production System. Now, Kaizen methods give managers and employees a better more efficient system to reach their goals within the organization or company.

Produktplacering : En studie om effektiv marknadsföring

PurposeThe purpose of this study is to investigate whether a combination of product placement and traditional advertising can enhance the company's marketing. We perform this study because we believe that the consumers consider traditional marketing in many cases obsolete.TheoryThe study?s theory consists of topics and terms of product placement, traditional marketing, branding and communications. Theories used in this study were the basis to answer the study's research question using empirical data gathered during the study.MethodThe study has a deductive approach with a qualitative focus, therefore, the study is based on existing research, which was later to use for the data extracted from the interviews. The approach is going to show differences and similarities between how it looks in reality versus theory.ConclusionThe results of this study show that product placement can increase the efficiency of traditional marketing.

Kategorisering av faktorer som påverkar flödeseffektivitet - En fallstudie på Capio St Görans Sjukhus

Swedish healthcare is in continuous need of cost savings and efficiency improvements in order to meet the increased demand for care. The theories of lean, developed from the industry, are applied more frequently on healthcare systems to increase effectiveness and reduce waiting times in patient processes. However, some processes seem to be more successful in their lean implementation than others. In this thesis, factors influencing flow efficiency in lean healthcare are examined. Through interviews with the top executive board at Capio St Göran's hospital, data is collected in order to analyze reasons for success.

Fejans vandrarhem ? En studie om isolering och uppvärmningsalternativ

During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.

Rengöring på restauranger : Kontroll och utvärdering av olika rengöringsmetoder på restauranger i Södra Roslagen.

Control and comparison of various cleaning methods on restaurants in Södra RoslagenThe purpose of this report is to find out and analyze the efficiency of cleaning methods in restaurant kitchens. The investigation was carried out through unannounced inspections at 89 restaurants in Södra Roslagen (municipality of Danderyd, Täby and Vaxholm). ATP-measuring was done on a plate, a knife, a bench surface and a cutting board. The ATP-method measured the amount of food residue on equipment and working surfaces after cleaning, with a luminometer and swabs. Restaurant staffs were asked to describe in detail how and when the last cleaning was carried out on the surface.

En usabilityutvärdering av Umeå Universitetsbiblioteks OPAC

This is a heuristic evaluation of Umeå university library?s Online Public Access Catalog (OPAC). It makes use of four of Nielsen?s ten heuristics, flexibility and efficiency to use, match between the system and real world, visibility of system status, and aesthetic and minimalist design. The evaluation was done by having 3 evaluators inspect the interface individually, as per Nielsen?s (1990) recommendation of 3-5 evaluators.

Kan buggning rättfärdigas? - En idéanalys av den svenska buggningsutredningen

The main focus of the essay is to investigate if bugging can be justified from two ethics perspectives, the teleological and the deontology. I?ve chosen to emanate from two specific values which I believe is especially relevant to the ethical problems of bugging, efficiency in fighting crime and the personal integrity. To be able to illustrate this conflict between different values did I do an analysis of an official report which had the task to explore if Sweden should introduce bugging as a new means of compulsion. The official report's statement was that the police should have modern instrument to fighting crimes efficient, including bugging.My examination of the report showed that they used several arguments derived from both the efficiency in fighting crime perspective and the personal integrity perspective.

Normering av en objektiv metod för att mäta käkrörelser med 3D-videoanalys vid tuggning samt en jämförelse mellan käkens rörelseomfång vid tuggning och tuggeffektivitet hos unga vuxna

This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.

Datorbaserad analys av enzymdesign för Diels-Alder  reaktioner

This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

Användarcentrerad Systemdesign

This essay focuses on the term usability while conducting a user centred system design. Usabilitymeans to what extent a user can use a product to achieve effectiveness, efficiency and satisfaction.Development using a user centered system design means that knowledge about the end-users andit?s opinions becomes a crucial part of the development process. The question of this essay is if usinguser centred system design will lead to good usability.We used methods from a user centered system design point of view while developing an applicationfor a Swedish bookstore company called Bokia AB. This included user and task analysis following by aclose relationship between the developers and end-users by using sketches and showing themprototypes of the system while collecting feedback.After concluding our case study we determined that using methods from user centered systemdesign could be used as a great tool to further improve the usability and to improve an applicationssuccess chances..

Peltierelement - spillvärme till el : Peltier element - waste heat into electricity

The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.

Språkinlärning och Språkutveckling : I en förberedelseklass i högstadiet

Then the language learning process and the approach in a preparatory class differs itself from a general class. The methods conducted in a preparatory class are not just focused on teaching as in a more traditional method. Achieving the objectives in a preparatory class depends on the individual student and the cohesion in the group. Students have different backgrounds and knowledge level, therefore it is extremely important that the teachers use different work methods in order to achieve and to promote the students' language development. The aim with this survey is to get the knowledge about what education methods is being used by teachers in a preparatory class.
