Utvärdering av informationssystem vid företagsförvärv: Synergiers påverkan på informationssystems integrationsroll
The numbers of mergers and acquisitions have increased significantly in the last period of time. Although this popularity for mergers and acquisitions, most of the mergers and acquisitions fail to create value. One explanation to this failure of value creation is, according to several studies, how companies treat integration of information systems in the pre-merger evaluation. The research within the field argues that information system integration should have a proactive role in mergers and acquisitions, meaning that information system integration should support the organizational change and normally be considered in the premerger evaluation. The aim of this thesis is to study issues that affect whether companies choose to consider information system integration proactively, when involved in mergers and acquisitions.
Leder icke användarcentrerad systemutveckling till låg användbarhet?
Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.
Värdeflödesanalys på Saab Training Systems i Huskvarna
Saab Training Systems (STS) in Huskvarna is manufacturing material for educationalpurposes to armies worldwide. They are now implementing parts of the Lean productionconcept in their organisation.One part of the work with Lean production is to eliminate waste. To be able to identify waste,value stream mapping is a good tool and also what we used in our thesis. To gain a betterefficiency in the production of Personnel Detector Device (PDD) flow was one of our goals.The PDD is a harness used during battle training which registers if the user is being hit by itsenemy.Our work with the thesis started up with a short education in Lean production and in valuestream mapping (VSM). The work proceeded with a VSM of the production flow of the PDD,interviews were made and studies of literature were done to gain greater knowledge of thesubject and solve the task.The VSM resulted in five areas which were followed up out of those six we identified.
Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg
In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.
Identifiering av merva?rden i EPC-projekt
In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
Betalningsförmedling enligt svensk och tysk rätt
A majority of the payments that are carried out today are executed through the electronic payment systems. Payments that are executed through these systems are administrated by payment service providers, these providers are, in general, banks. In spite of the socio-economic importance of payments and payment intermediation, there is an uncertainty regarding the legal status of payments and payment intermediation. Some describe payment intermediation as transport of means of payments, while some describe it in terms of claims and intermediation of information. There is, in other words, a need for clarification.
Inhysningssystem för kalvar och ungdjur i större besättningar :
In Sweden, there has been a continuous increase in the volume of housing construction for
dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.
Skadedjursbegränsare i horisontella avloppsrör
The purpose with this project was to invent a product that secures buildings sewersystems against rats. The problem was presented to us by a local building maintainer inHalmstad, who had experienced big problems with rats in his real estate. The project hasbeen carried out by Per Johansson, Robert Lidén and Niclas Nilsson under our ownauspices. We are primarily sponsored by AMLI Business Partner but also byInnvationsgruppen, Halmstad Fastighets AB and Anticimex.To be able to secure a whole building with only one product we came to the conclusionthat the product must be placed in the horizontal sewer pipe that connects with themunicipal sewer system. Our goal was to invent a product that prevent rats from passingand at the same time not affect the water flow.
Samling i förskolan : ? en rund stund med mycket mening
The purpose of this thesis is to gain insight into educators? views and work with circle time in preschool. To find out, I have referred to the following questions: How is your circle time performed in preschool? What objectives have teachers with the circle time? What impact has your circle time for the children in preschool?I have chosen to carry out qualitative interviews with three preschool teachers. After the interviews, I compared the educators? response to previous research.The survey shows that the circle time is one of the day´s highlights for preschool children.
Tid i all oändlighet och förgänglighet. En studie av tidsanvändningen i Sverige sedan 1980-talet
This master thesis in economics discusses the time use of today as well as the observed trends in time use over the last 20 years in Sweden. This is done by analysing time-use and consumption data at the microeconomic level, i.e. by explaining individual behaviour given the economic assumption of a rational behaviour. We reach the conclusion that the value of time is an important explanatory variable concerning the rationality in that time is used differently by different individuals and in the changed use of time. Furthermore, other variables such as social norms and the process benefit of a certain activity, i.e.

"En skola för alla" : verklighet för elever med läs- och skrivsvårigheter och dyslexi?
Many researches have been done about the difficulties in teaching children with disabilities and like in this case dyslexia, which is the disability my essay is focused on. Earlier researches have investigated how and what teachers do practically when they have pupils with dyslexia and what help they have in their work. I wanted to investigate how the theories in National Compulsory School Curriculum (Lpo94) and about inclusive education in relation to the actual work in one Swedish school. My essay, with help of other research, has taken the expression ?school for all? and it?s meaning to what is possible to do in a real life work situation, with the assignments that schools have in Lpo94.
System 348 - Rekombinator : Analys av reglerproblematik vid O2
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
Utvärdering av produktionsledarens användning av Holmen Skogs datorbaserade stödsystem vid operativ planering av avverkning
The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems.
The aim of this study is to:
? investigate the work pattern of the production managers when using the information system to plan the harvesting operation;
? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system;
? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern;
? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion.
The conclusions of the study were:
? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning;
? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information;
? the computer systems are however divided in many subsystems.
