Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

In this day of age there is no clear definition of what leadership is and exactly what it means. Though something that all existing definitions of leadership have in common is that, it is a process of influence where the leader exerts influence over their subordinates. The concept of leadership can at first glance be seen as a clear substance that is easy to understand. However, this is not the case when one delves into the subject and begins to realize that leadership is a complex concept which includes a variety of things. How to best exercise leadership is a divided perception that may be completely different, depending on whom you ask the leader or the follower.In this paper the aim is to explore the leadership within the company Lycamobile located in Sweden, with respect to management.

The aim of this Master?s thesis is to identify and describe thedifferent roles that are expressed in a public library by researchingthem in the four policy documents concerning Västerås public libraryin 2010 and by interviews with three specially chosen key persons.Further studied are the discourses that can be perceived in thematerial and whether or not the roles could come in conflict witheach other. Laclau and Mouffes discursive theory constitutes themethodical frame for this thesis and by using terms from discursivetheory the analysis was made in four steps.Seven roles were identified from the policy documents concerningVästerås public library and the interviews with the key persons. Thefirst role of the public library was the intermediary of knowledge andinformation, the second was viewed as a democratic role, the third asa marketing role, the fourth as a role that handled the collaboration,the fifth role was to improve literacy, and the sixth and seventh roleswere as a culture centre and a meeting place. With the help fromkeywords five major discourses were found within the material.

Att arbeta som sjuksköterska inom ambulanssjukvården innebär stor frihet under ansvar. Vid behandling av smärta finns olika behandlingsmöjligheter att tillgå. Sjuksköterskan har stor frihet i att själv bedöma vilken behandling och dos som skall ges i varje enskilt fall. Detta medför att behandlingen av patienterna kan variera mellan olika sjuksköterskor beroende på tidigare erfarenhet med mera. Traumapatientens upplevelse vid prehospital smärtlindring är sällan beskriven i litteraturen.

A global world and international business induces not only opportunities for organizations such as increased possibilities to reach new markets but also challenges to maintain a coherent business. To meet these challenges, organizations need to harbor a global workforce where employees are sent abroad. These employees are called expatriates and receive very lucrative compensation packages to cover their increased expenses. Compensation packages are not only expensive but represent in their totality also a complex strategic challenge for both the organization and the expatriate. The purpose of this paper is to investigate which components of a compensation package that are important for different segments of expatriates.

The purspose of this study is to investigate how teachers are working to individualize mathemathics education relative to high-performing students and how they define the therm individualization. According to the Swedish curriculum the teaching process should be based on the students prevoius knowledge and experiences. The teachers should in their preperation take every student in to consideration. To be able to investigate these subjets I prepared following questions:What does the concept of individualization in mathematics mean for the teachers?What does it mean to work with an individualized mathematics teaching?How does teachers individualizes teaching mathematics relative to high performing students?This study is based on a qualitative method with both interviews and observations.

Today?s construction buildings contain more advanced technologies than before. The development of newer and stricter regulations to the construction industry makes the door environment more and more complex.In large construction projects the door environment is held up as a major challenge to get to in a good way. It turned out after a discussion with one project manager and a site manager at NCC, that the door environment is difficult to get right in major construction projects and it often causes many error reports in to the aftermarket after that the final inspection is completed.Interviews have been done with key figures in the building process at NCC and Akademiska hus. A study on a university building for around 3500 students and with 300 workplaces was made.

According to some researchers, dyscalculia is at least as prevalent as dyslexia. Somewhere between 3.6-6 % of all pupils have specific mathematics difficulties named dyslexia. If this be true, it should present the most complex special education predicament by far in schools today. Despite the statistics, dyscalculia is still a rather unknown concept.The cause of dyscalculia is not yet fully analyzed. There are several theories and many researchers see similarities between dyscalculia and the special educational problem of reading and writing, dyslexia.

The aim of the study is to get a better understanding of leader's reactions in a crisis situation, and to examine whether locus of control and coping strategies can be related to leaders need for social support. The role of a leader in a crisis situation is complex and includes several aspects which must be illustrated to understand the leader's situation. Four leaders have participated in the study. The methods that have been used are questionnaires for measuring locus of control and coping and semi-structured interviews. The results show that search for social support cannot be seen as an outcome of a specific locus of control or coping strategy.

The concept of large paintings includes panoramas, cycloramas and other paintings thatin size exceeds the normal magnitude of wall hung paintings. When these large paintingsare mounted in the ceiling, they are referred to as plafonds. When they are performedon canvas, certain kinds of structural distortions and stress occurs. In addition, becauseof their size and mounting high up in the ceiling, plafond paintings are often difficult tohandle, which leads to less or no maintenance. A plafond may therefore be left withoutattendance for many decades.This thesis has its focus on what happens with plafond paintings on canvas when they areexposed to gravitational forces, and the problems involved in restoring large paintingsmounted in the ceiling.

As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.

Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.

Requirements management is an important part of the software development process. The success of a project may depend on how this is handled. Even though several research studies indicates that more attention should be paid on non-functional requirements, the primary focus in practical projects still regards identifying functional requirements. Especially the prioritization of the non-functional requirements has been proven to be of great importance for the success of a project.This report investigates basics in agile requirements management involving opinions from experts from a software development company. This is done with help of existing literature and interviews with key actors involved in prioritization at the company.

At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.

In recent decades, project based work form has taken a dominant role of work for many companies. Developments in the field have progressed rapidly and research has contributed to more efficient working practices. This study describes the elements that a project manager should keep in mind when he leads a project without actually being physically present, complex factors occurred and the basic approach to encounter them. The aim of this report is to examine factors that arise in the context of coordination at a distance and how companies, in their daily work, surpass these obstacles. The study does not include cultural differences, time zone differences and language differences, all very common in project management at distance.
