Hantering av informationssystem
Lund who has over 90 systems in 12 departments and now wants to streamline the management of these IT systems. Governance of IT systems is something that Lund would treat as it carried a large amount of changes in their practices, where the control is something missed in trying to standardize their systems. What's missing for Lund Municipality is routine to fall back on in order to streamline the management when they get into these complex situations.Given that Lund treat so many systems make it so that the situation quickly becomes very complex due of the organization's structure. The municipality is divided into twelve departments that have their own goals, it is an organization that is organized, which makes creating standards become complicated when all departments have different needs. Our study was based on a framework that deals with complex environments that lack a clear definition.An analysis was conducted where we started from the theory associated with the interviews conducted in which we aimed to understand their decision and understand the processes that affect system development.
Analysis of Intent Specification and SystemUpgrade Traceability
The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.
Mätning av Mikroläckage i Dentala Implantat
Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss.
The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.
Developing Dynamic Outsourcing - Bringing continuous added value to the ABB Full Service partnership
Executive summary This master thesis was originally based on a specific assignment given to the authors from ABB Full Service, a unit specializing in providing maintenance outsourcing: ?How can ABB Full Service expand its offering of providing fundamental maintenance by seamlessly incorporating the business concept with competencies and solutions from other ABB divisions?? The academic issue was developed throughout the thesis, resulting in the following formulation: ?From an organizational perspective; how can service providers bring continuous added value to intra-organizational outsourcing partnerships?? Many of the key findings of this thesis are reflected in the issue. The term intra-organizational outsourcing is a proposed addition to the terminology in the academic discourse on outsourcing. The definition of the term is: ? Where an organization outsources a business process interlinked with the physical operations, requiring the service provider to take over a preexisting unit and its employees.This is an accurate description of the form of outsourcing that ABB Full Service is engaged in.
Energivinst vid hybridisering av hydrauliskt system
Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.
Elektronstrukturbaserad magnetiseringsdynamik
In this project a method used for performing accurate simulations on magnetization dynamics based on constrained field density functional theory has been validated and used for performing computations on a few magnetic materials. The method has been shown to simulate systems consisting of iron well, but there are still problems with simulations of alloys containing both magnetic and non-magnetic materials..
Säkra kommunikationskanaler i en distribuerad heterogen miljö
The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.
OSE och Linux : En studie om prestanda
There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..
Metoder för idégenerering : En kartläggning och utvärdering av metoder på ASSA AB
ASSA develops locks and integrated security systems for doors. ASSA is Sweden?s leadingsupplier of locks and security systems. ASSA AB worked during the master thesis withimplementing a common development process for all companies within the group. Ideageneration was one relative unexplored area for the group and the interest of finding effectivemethods was required, the company understood what an effective handling of ideas couldcontribute in the pursuit of more and pleased customers.The purpose of the master thesis has been to study and to map which methods are used inorder to carry out idea generation.
Undersökning av elektroniska scorekort på golfmarknaden : Var ligger problemet för fortsatt utveckling?
This is a Master´s Thesis based on my own idea instead of that of a company. It is a survey that focuses on finding out more about which part of the development process that is blocking the establishment of electronic scorecards on the golf market. Why has it not been introduced on the market in a larger scale yet, considering the technology we possess today? This question is investigated through interviews with the Swedish Golf association, and three companies that have chosen different paths to implement an electronic scorecard. The interviews focuses on finding out what developers and the association believe to be the main problem, before taking the next step in releasing electronic scorecards on a larger scale.
Dynamisk modellering av VSC-HVDC : En statisk och dynamisk modelldesign o?ver VSC-HVDC fo?r implementering i ARISTO
This thesis treats the subject of a complete steady state and dynamic model of the VSC-HVDC covering both the AC and DC system-side of the converter. The topology of the model is recreated after the scheduled transmission line in the south of Sweden, called SydVa?stla?nken. The topology covers both a simple two terminal connection as well as a multi-terminal one. This model is to be implemented in the power system simulation program ARISTO.
Vad innebär övergången till Scrum? : En studie som undersöker hur Scrum påverkar systemutvecklingsarbetet i globala organisationer
Currently many organizations are transitioning from the traditional approach to the agile approach regarding systems development methods. It is evident that research has mainly focused on smaller organizations transitioning, whilst less focus has been given t0 larger organizations. We find this interesting and the purpose of this study is to gain a deeper and broader knowledge concerning the following research question: How is system development work affected by a change from traditional system development methods to Scrum in large global organizations. We also investigate how Scrum can be adapted to complex projects with an internal client. The study is based on a case study, which takes a qualitative approach with semi-structured interviews for information gathering and was conducted on a major Swedish telecom company.
En lärande organisation? - Kompetensutveckling inom en Polismyndighet
This essey discuss competence development for the employees in a unit of the Swedish police authorities. The purpose with this survey has been to show an understanding for how this unit within the Swedish police authorities works with competence development and what kind of competence investments they carry out and also why competence development is important in their organisation. To answer the purpose of the survey and the questions a qualitative method has been used remaining interviews with five involved respondents working in the investigated unit. The result shows that needs for competence development are made clear during meeting for personal development and during the local educational council inventories. Competence development for the employees is prioritated for the policemen comparing to the civil employees on account of that the policemen have a demanding work and they have to develop their work all the time because of the resisting circumstances.
Klassifikationssystem på webben: Traditionella och nya
The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.
Utvecklingssamtal - utifrån elevens perspektiv
My aim with this diploma work is to find out if the students consider development deliberations as a good forum in order to promote their knowledge development or not. I have also examined if the development deliberation is experienced as giving for the pupil or not, what I have been studying from the pupil's perspectives.MethodI have implemented three qualitative interviews with three students from class nine in a compulsory education that lies in Botkyrka municipality. There, I have also an implemented questionnaire survey with two half classes from same class.Materials To my study I have linked literature where research aims himself in on how teachers have worked with development deliberations in the school.Results Students that I have interviewed does consider development deliberations as a knowledgep romoting forum, but most as a forum for clear about study results. The students in the survey consider development deliberations as giving only when the result turns out to bee good.Importance for teachers As each development deliberation is unique, you can not come to a certain implication that all deliberations are experienced in the same way as the result shows. But that can last stakeholder for the teacher is to see how one development deliberation can to be experienced of several students.
