In the haulage business customers are constantly requesting new features. Hence thedevelopment department must constantly update their system which ultimatelyresults in a variety of versions of the system. The large number of versions creates acomplexity which often reduces product quality and extends the developmentlifecycle time.The work on the following thesis has taken place at Scania?s Fleet Managementdepartment, which develops tools for hauliers to track their vehicle fleet in real time.The purpose of this thesis was to examine how Scania can handle an increasedamount of versions of the Fleet Management System which Scania expect will be seenin the future. The investigation was conducted by preparing a number of differentscenarios that formed the basis for a discussion of what these different scenarioswould mean for different parts of Scania?s business.

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

Youths tend to have a bad reputation. Their outspokenness and spontaneity are two of many reasons to why they are seen as rude and disrespectful. The creativity, curiosity and not least the courage to have opinions and attitudes are in such young age not yet weakened. Youths, their thoughts and attitudes change quickly. This essay will deal with a selected group of youths and their attitudes to the surrounding society.

The purpose of this study is to increase understanding of the unemployed youth. To achievethat, we have investigated who the unemployed young people are, how their wellbeing isaffected and what they need for a change to take place. The study was conducted in amedium-sized Swedish city with the help of a method combination. The target population forthis study is people enrolled in ?Job-guarantee for Youth? in spring 2014.

The purpose of the essay was to discover how homeless persons want to live. Does it matter what it looks like? The method used was a qualitative study including literature and 10 interviews with ten homeless persons, of which seven lived outdoors and three in temporarily residences. The central questions were the following:How do homeless people want to live?In what sort of houses do they want to live and where?How do they look upon their situation and their future?What obstacles can occur if they for example got an apartment to live in?Are there any proposals to solve the problems?Most of them had been living outdoors for five to ten years, perhaps more, and they were worried and sad about their future.

This thesis deals with an iterative user-centered IT-development project in a bank setting. The aim is to present a solution for deployment of future Internet banking for small businesses. The project features a design of IT-related concepts and ideas with a strong emphasis on scenario-based design and the usage of patterns as a documentation tool.The project plan featured an iterative framework and was carried out by a group of designers in collaboration with a reference group representing the future users of the system. This group consisted of company managers and bank employees, all from the small town of Åtvidaberg in Sweden.The method used in the development process was Scrum. A total of three sprints were completed with user meetings at the end of every sprint.

This survey was made during the summer of 2004 and the spring of 2005, on commission from the National Board of Forestry. The aim of this report was to investigate how often Norway spruce (Picea abies L. Karst), is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In 20 plots in each stand, the highest tree, age, number of seedlings, site index and tree species per stand were measured.

The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..

This study focuses on carpooling and how carpools can be better integrated into today's society. The purpose of the study is to investigate what affects the motorist?s decisions to become a member of a carpool. The study will highlight the barriers and drivers of membership in a carpool. It is important for the future to change the attitude of motorists and get more motorists to choose more sustainable modes, as is the concept of carpooling is a good solution.The study is based on a qualitative approach with six respondents from the Eskilstuna municipality.

In the future the Swedish pension system will face major problems. With an increasing aging population combined with a decreasing share of working population the financing of the pension system is becoming a bigger problem than previously predicted. This means the individual himself will have a bigger responsibility to invest money for their future retirement. It has been shown that a large proportion of the people who invests for their future pension have neither the interest nor the time to actively invest their pension capital. To make it easier for those who invest for their retirement, some Swedish banks have created so-called generation funds.

Presently Sjöfartsverket do their maintenance according to a standard program, which means that every maintenance task will be done when the task limit occurs. This leads to a very long downtime for the aircraft in some occasions and very short downtime in others. The goal with this work is to reach a higher regularity of the aircraft operation. To reach a higher regularity for the operational needs, this work will present a hypothetic better maintenance concept for Swedish Maritime Administration. The concept is based on equalized maintenance structure, which means that every maintenance occasions are meant to take the same time to perform.

The last 1½ decade young people with intellectual disabilities have been a part of my life. My now 13 year old son and several pupils I have taught as a teacher in the compulsory school. Their future and what will affect their lives has always been interesting to me. How do I affect them, why do I do the things I do and think the way I think? This study springs out of that curiosity.

 There is an ongoing reorganization within media industries today as they adapt to new and changing demands - the environment is changing fast and the organizations with it. The development of new technology is contributing to new forms of media distribution in the present media industry. The structure of media organizations is getting flatter and the co-workers are getting a new and bigger role. All this is bringing new challenges for the leaders of the organization. Caught in the middle of these new structures is the middle manager who now is facing different demands from all sides.
