Tillämpning av UML : Hur och varför

In the end of the 80´s the area of system development moved into a new era. As a consequence many new methods and development models emerged which in many cases resulted in problems when choosing system development models and methods. As a result of these problems the today standardized modeling language UML (Unified Modeling Language) was created. UML is tailored to support many different types of projects. This is possible because of UML?s capacity to be adjusted and adapted to a specific company environment.The purpose of this bachelor thesis is to investigate how and why companies use UML and what experiences and opinions those who use UML have of using UML in practice.

En studie om hur finansanalytiker tillämpar aktievärderingsmodeller

Background: The interest in shares has increased over the years, despite several stock market crashes. One reason for this is the emergence of stock trading online,which makes it easier for individuals to trade in shares. However, there has been much criticism towards financial analyst with the lack of fundamental basis to support their recommendations.Objective: The purpose of this study is to examine the share valuation models swedish financial analysts today applies and consider appropriate. A comparison will also be carried out in previous studies, to see if the application of the modelsand their suitability has changed.Method: The study used a qualitative approach with deductive approach. Semistructured interviews were conducted and the basis for the study's primary data.The theories and previous studies obtained through secondary data.Results: Our results demonstrate that no single model applied, is appropriate.

Aktiv lastbilsstol för bättre förarergonomi och hälsa

The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.

Att ämnesbestämma bilder: En teoretisk undersökning

The aim of this master ´s thesis is to understand why there are difficulties in finding joint methods and standards in the field of image indexing. The main focus for interpreting these issues is on Sara Shatford ´s article Analyzing the Subject of a Picture: A Theoretical Approach. In the article Shatford discusses a theoretical basis for identifying and classifying the subject in a picture. In doing so she uses concepts taken from The Philosophy of Art, Meaning in Language and Visual Perception. With the aid of S.R.

Reglering av matarsystem vid höghastighetskapning

Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.

Barns självkänsla : en studie om hur pedagoger arbetar med barnets självkänsla i förskolan

ABSTRACT  Title:                                       Artifacts as transformational leaders ? A case study at SIBA. Course:                                   Bachelor Dissertation - Leadership Authors:                                 Tobias Barin and Victor Eriksson Advisor:                                 Anders Billström Keywords:                             Artifacts, transformative leadership, organizational culture and leadership Problem formulation:          Which artifacts can be transformative leadership in the electronics industry?  Purpose:                                Create an understanding of store managers and deputy store managers' perception of how artifacts can be expressed in the transformational leadership.                                                Creat an understanding of the importance of artifacts in leadership in the electronics industry. Theoretical framework:       The study?s starting point for the theoretical framework has been Schein (2004) earlier theories of organizational culture, and Bass (1985) theories of transformational leadership.

Personal interviews were conducted with two store managers and two deputy store managers at SIBA. Conclusion:                           We have found that the artifacts: role-models, stories and rituals communicate the transformative leadership. Respondents have described how these artifacts conveys organizational culture but also the transformational leadership..

Individanpassad omvårdnad : ett steg mot optimal stationärvård för hund och katt

When nursing human patients during hospitalization, the nurse is the one responsible. The nursing is controlled by different models of nursing and careplans, shaped by every patient?s individual needs. This is to guarantee the quality of the care. The veterinary nurse is not ultimately responsible for patient care.

Kommunikation inom projektering. Hur påverkar visuell planering och projektkontor?

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

Prestanda på luftfilter : En jämförelse mellan olika filter till bil

This reports goal is the give BSR AB more information that's useful towards their customers in marketing of their products.It involves tests of different air filters designed for cars and 3D-modelling of Opti-Flow systems. The three models thats being tested is SAAB (93SS), VAG (1.8T) and Volvo (S60). To every brand there are three different models. A orginal- , sport- and an open cone air filter (Opti-Flow).The results indicate that the open Opti-Flow filter has better performance compared to the other cased filters. The sport filters for SAAB and Volvo has better performance then the original filter.

Manusutveckling av digitala läromedelsapplikationer i matematik : En studie av samtida pedagogisk forskning och utveckling av applikationsmanus för matematikämnet i gymnasieskolan

In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

Anknytningens förändring och stabilitet i vuxna parrelationer: en integrerad helhetssyn

Several Theoretical models of change exist concerning attachment, but an integrated view and knowledge of the role separate factors of change play for the individual is lacking. This phenomenon is hereby studied by semi-structured interviews of 20 persons. Change and factors of change are examined statistically with affectregulation as measure of attachment. The results show that these individuals´ changes are small and mostly towards secure attachment. Metacognition is related to greater change towards secure attachment.

Med Tron Som Vapen : Legitimering av våld och död hos en japansk religiös sekt

This study was performed to investigate how the Japanese sect Aum Shinrikyo was legitimating its violence and killing acts. By analyzing the leader and members of the sect, and applying this information on two Theoretical models, this paper tries to give an explanation of both single acts of violence and killing, and two terrorattacks.The result shows that Aum Shinrikyo was able to legitimate violence and killing acts through its ideology. In their opinion, cosmos was a place with several levels and everyone wanted to get as high as possible. Those who were killed by the sect would never be able to get to a higher level by living, since they would do too many bad actions. The murderers also got better karma since they helped the person to a better place.The legitimating of violence and killing acts in Aum Shinrikyo can be explained as a duty that is holy, which agrees with the theorists about religious terrorism..

Kommunfullmäktigeledamöters sociala representation -en fallstudie i tre svenska kommuner av kön, ålder och etnicitet

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

Hur prissätts digitala dagstidningar i Sverige - En fallstudie om tre tidningars resa från gratis till betalvägg

Printed newspapers are on the decline, while digital versions are in rapid growth. Consequently the industry must draw up new business models around the digital format - models that can produce revenue streams equivalent to those that the print format used to produce. However, after a decade of 'free' online news, consumers now hesitate to pay. In their struggle for survival, strategic pricing is a central issue for newspapers. This study aims at describing how Swedish newspapers price their digital content, by analyzing their pricing processes and five factors that may influence the choice of paywall and price levels.

Informationsutbyte från BIM-modeller : Från BIM-modell till format hanterbara av förvaltning- och GIS-system

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.
