When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

Prioritisation of software requirements is a critical part of the development of software. Whichrequirements and in which order they will be developed is one of the main tasks that requirementprioritisation supports.There are different ways that a requirement prioritisation can be used, for example alone or in agroup and with different methods.The purpose of this report is to map out how you can carry out a requirement prioritisation alonewith different types of prioritisation methods and how you solve the problems that can arise whenprioritisting requirements. This is done by documenting the use of three different types of methodsthat can be execute alone. The methods are "100-dollar test", "Ranking" and "Top-tenrequirements".To be able to prioritise requirements, you need to establish which requirements you shall prioritise.The paper retrieves this information by interviewing stakeholders in the system and analysing theresult of the interviews and the execution of the requirement prioritisation.Three problems arose during that work and I present solutions on these problems. The problemswere 1) equivalent requirements when using the "100-dollar test", 2) low differentiation gradebetween the prioritised requirements in the "100-dollar test" and 3) that the requirements that wereprioritised weren't classified before the prioritisation, which leads to inaccuracies in the resultingprioritisation.The solution to the problems that the paper presents is to increase the amount of distributable unitsin the "100-dollar test" to 1000 per requirement, suggestions of classes of the requirements andthe combination of the methods "100-dollar test" and "ranking" to bypass the equivalentrequirements.The report is written in Swedish.Nyckelord: GoTRIS, requirements retrieval, requirements analysis, Viktoria Swedish ICT,requirements prioritisation, requirements, 100-dollar test, ranking, top 10 requirements..

En studie om det kommunikativaklimatets förändring.Author: Anne BjörckAim: The aim of this essay is to study changes in the area of the communicative climate and link that to Karl Weicks thoughts on communication and change. Karl Weick is famous for his contribution to organizational theories and he is still very well used around the world and that is the main reason to why his theory is served as a base in this essay.Method: The essay has a theoretical base with elements of qualitative explorative research method.

Purpose/Aim: The aim of this essay is to study the expectations towards the launch of an intranet in a large organisation.Material/Method: A qualitative method has been used to fulfil the purpose of this essay. Indepth interviews have been made with eight informants of dioceses.Main Results: The study shows that the eight informants of dioceses all are positive towards the launch of an intranet in the organisation. They believe that it in time will lead to a more effective intern communication with less channels and more efficient messages..

Bolivia is a multiethnic country where the indigenous people constitute the majority of the population. Despite two decades of attempts to take the democracy further is its foundation more volatile than ever. The aim of this bachelor thesis is to examine if exclusion is taken place in Bolivia from year 1982 until today and if so in which way political exclusion constitute problems of democracy in Bolivia. The answer depends on the understanding of democracy used in the analysis. In this thesis I use theories of process-, participation- and deliberative democracy.

The purpose of this thesis is to find out how clients at Effect Reklambyrå (an advertising agency) view the communication and relationship with Effect. Conclusions are then drawn based on what the clients say. The conclusions show how Effect can improve in these areas.The study uses a qualitative research method since the phenomenon studied is complex and requires deep understanding. A total of 16 interviews took place. Seven clients were interviewed by phone and nine clients participated in a personal interview face-to-face.

The aim of this study was to evaluate parents and course leaders'perceptions of ComHome, a course in communication for parents.

The purpose of this dissertation is to create an understanding of how a personal idea in the mind of an entrepreneur becomes an outspoken vision in one biotech company. More specifically, for what purpose the vision is used at different stages, how it is communicated, its content and what impact previous visions have on future vision work and in order to reach a deeper understanding of how vision develops over time and how it is used we have employed a qualitative approach based on a case study. The theoretical framework starts with the concept of vision and related concepts. Furthermore, the entrepreneur?s and manager?s usage of vision is examined.

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

The purpose of this bachelor thesis is to examine the different ways thatFamiljehemscentrum use to increase the number of families that show interest in takingcare of foster children. This thesis will examine which families are targeted by Familjehemscentrums present communication, which families they should target in thefuture and also the best way to do that. In order to answer these questions a number of interviews were conducted. The first interview was a group interview with three social workers that all work at Familjehemscentrum. Three more individual interviews were conducted with representatives from foster families to investigate how they were recruitedand what they think about being a foster family.

Problem: The relations between first and second tier suppliers within the automotive industry have changed drastically during recent years. Previously involving the supply of simple components, today the relation involves collaborative product development of complex subsystems. The situation is rather new for the actors, hence there are a number of problems that act as restraints for the collaboration. In order to come to terms with these problems, it is important to determine the underlying causes. Purpose: The purpose of this thesis is to make a survey of the main problems in the collaborative product development between first and second tier suppliers within the Swedish automotive industry.

Result: The scientific hypotheses whichexist is based on whether social capital increase or decrease due to internet use. The healthoutcome is positively affected by internet communication, especially for boys and socially anxiousadolescents.

AbstractTitle: A democratic organisation - one click away? A quantitative content analysis which studies the potential of democratic communication through intranet use.Authors: Stina Gabrielsson and Jill Johansson VennelinPurpose: The purpose of this study was to investigate whether there is potential for democratic communication within the NGOs through intranet use.Key questions to be answered were: To what extent is authority versus members represented on the intranet Klick?s discussion forum? What/which communication-related functions out of social function, knowledge transferring and debate are featured in the posts published on the intranet Klick?s discussion forum? Are deliberative discussions being practiced in the discussion forumthreads on the intranet Klick? The thesis is based on the theory of deliberative democracy. In order to substantiate the theory has theoretical perspectives concerning participation and involvement also been applied. These perspectives are derived from organizational theory and internal communication.Method/Material: This study consists of a quantitative content analysis of the 477 posts and the 129 discussion threads available on the NGO RFSU?s intranet Klick the 29th of november 2012.Main results: The results show that 63, 4 percent of those who were active in the discussionforum represented the category authority, while the category members were formed by 36, 6 percent.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.
