In this thesis we study four groups of students in grade 8, 9 and 10 when they try to solve a classical mathematical problem: Which rectangle with given circumference has the largest area? The aim of the study was too see how the students did to solve a mathematichal problem?The survey shows that students have rather poor strategies to solve mathematical problems. The most common mistake is that students don?t put much energy to understand the problem before trying to solve it. They have no strategies.

Redovisning av leasing ? efter form eller substans? RR 6:99 innehåller kriterier som ger ut-rymme för tolkning.

Syftet har varit att förklara varför en del företag redovisar finansiell leasing off-balance. Vår studie har angripits genom en enkätundersökning riktad till 67 börsnoterade industriföretag, svarsfrekvensen var 54%.

Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

To understand the glass electrode needs knowledge from more than one level. The construction ofthe glass electrode is one part, an other is the composition and structure of glass. The Nernstequation have an important role, but also the sources of errors in the analysis and the calibration ofthe glass electrode. Focus for this article is how the glass electrode really works and how Gibbs freeenergy made the potential dependent of the concentration of H+and gives the logarithm to thefunction. Nikolskii's ion exchange theory starts to explain the question about how the potentialcreates and Baucke's dissociation mechanism made it more explicit.

Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.

AbstractIn the secondary-school program for hotel and restaurant complete courses or parts of courses are placed in workplaces so called workplace education (APU), this means that the content in the course plan must be discussed and be divided in a proper way between the school and the workplace, so that the students is gaining all the parts that is prescribed in the goals for the course.Interviews with tutors and teachers have been performed, with the purpose of investigating how the collaboration between the school and the workplaces should look like so that the APU fulfills the content and quality that are prescribed in the specifications of the education. The study shows that a better structure for collaboration between the school and the workplaces is needed. Lack of time and financial resources are the factors that according to the study reduces the possibility?s to (among other things) perform education of tutors, and for the teachers to plan and follow-up the APU-period..

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

Background Being outdoors on a regular basis is beneficial for all individuals, people with dementia who is living in special accommodation have not always that possibility. If the person with dementia live in a stimulating environment can contribute to the person's functions are maintained. Aim To provide a basis for evaluation of a new outdoor environment at a special accommodation for people with dementia. Method of data collection in action research was done through focus group with staff on the accommodation and the participants in the project, a total of five informants.

In the field of municipal services there are a wide range of aspects a small community must consider, especially considering that the circumstances in which a municipality operate continuously are changing. The changes include, for example, migration, individual lifestyles, the political governance and environment. Especially the latter might have a big impact on a town based on tourism such as Borgholm. We particularly have taken an interest for how this might affect the internal branding and internal brand communication of Borgholm municipality.Through our research we have found that Borgholm municipality in no particular extent is working with living the brand or any similar concepts. Also, we have found that the success of the internal branding of the organization in a great extent depend on the individuals of the different branches of the municipality?s work rather than on a coherent communication structure which reaches the whole organization..

The essay is a text centred study of ten Young Adult Novels, in which Internet plays an essential part. The structure is put into light out of used narrative techniques of how to create stories and its construction elements. I compare the ten Young Adult novels to each other. My aim is to analyze the functions of the Internet motive in the chosen novels, using different approaches, and enlighten it with concerns to the new phenomenon that Internet is in society. Consequently the essay will also have a mimetic touch to it.The ten novels that I base the analysis on are written of both med and women and have both male and female as main fictive persons, and are from different parts of the world.

Stress is commonly found in society today. This paper aims to examine how work performance, cooperation and team spirit are maintained in demanding work environments. By studying two departments in a public hospital that practises addiction care, our findings suggest the following: If the experienced stress is mainly connected to challenge stressors, it has a positive effect on work performance. By organising work through mechanistic and organic structure, the handling of qualitative and quantitative stress is facilitated. As a consequence, first and foremost cooperation can be maintained, but also work performance and team spirit.

In the last two decades something called ?the Eleatic Principle? has been quite frequent in philosophical literature. A wide range of philosophers have appealed to this principle when arguing for varioustheses but the principle itself has received comparatively little attention. Especially questions regarding the principle's justificationare often ignored or only mentioned in passing. The aim of this paper is to remedy this situation somewhat by focusing on how it could be justified.In section 2 I give an overview of the various ways in which the principle has been used to clarify just what we are dealing with here.

The structure of the thesis is based on opportunities to attract businesses to the region, the need of establishments in the region and benchmarking with establishment strategies of other cluster initiatives. The identified opportunities are the local business relationship with ABB, the prerequisites of life quality in the region and the availability of financial support. Further on has a number of opportunities to be developed been identified; diversification of the existing businesses, an expansion of the cooperation with universities and to simplify the contact with local authorities. Challenges that HVV is facing is: creating a more dynamic labor market, secure long-term labor supply, spread the image of the brand HVV and finally putting HVVs geographic scope. Two of the identified needs of establishments are strategically important: to establish a third-party logistician and commercializing systems for distributed generation and energy storage.

Normally when purchasing a trip, an airline, a travel agency and a traveler is included in the purchasing process. Mostly a travel agency acts as an intermediary between the airline and the traveler. The travel agency is not considered to have any major part to the contractual relationship, usually the purchase agreement is considered to be covered by the airline and the traveler as the main parties. This is essentially the view shown from a legal perspective on the specific area. The application of legal provisions on the travel agency?s legal status may nevertheless bring a certain amount of ambiguity in the interpretation.
