Informations- och kommunikationsteknologiers betydelse i utvecklingsarbete : En intervjubaserad studie om IKT:s betydelse för indiska kvinnor
New forms of Information and Communication Technologies (ICTs) have become more influential in development contexts. The concept of ?The Digital Divide? points at a large division between rich and poor countries regarding access to ICTs. Critics say that the debate concerning this topic for far too long has focused mainly on the technology itself rather than social factors which impact social inclusion and development. Scholars agree that ICTs holds a tremendous potential, but how is this implemented in development contexts and how can it be used with more sensitivity towards local preconditions and social aspects?This paper aims to examine how ICTs are being used in the context of development within an India based organisation for women called SEWA (Self Employed Women?s Association).
Torkat bioavfall som jordförbättringsmedel
The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.

Mitt emellan eller kraften till källan? : En studie om mellanchefer i en ny omgivning
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.
Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn
This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

Perceptions of domestic solar systems : a study on non-adopter views of a new technology
The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany.
The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.
Mätningar och analys av elnätet hos FHP, Basproduktion
This report is a degree project performed at Freudenberg Household Products AB, (FHP). The degree project comprises measurement and analysis of the power net at FHP Basproduction. The content is divided between one theory-part, one document- part with measurements and also conclusions and a list of measures to be taken. During the project the purpose and restriction change from a quality investigation to only concentrate on harmonics and finding the reason why they exist, and also to find a solution to the problem with harmonics. The measurements shows that the power net contains harmonics of different order and intensity.
Jämförelser av olika former av QRA och andra metoder för riskanalys av processindustrier
When performing a QRA you have to consider a number of accident scenarios. How many scenarios you choose often determines the time and resources needed to perform the QRA. The report investigates the possibility that a QRA can be performed using only a few representative scenarios. Further it presents a discussion on how these scenarios should be constructed..
Ett kreativt samarbete
Vi ämnar, med denna uppsats, att utforska det kreativa området efter ett
fenomen vi valt att kalla för Det kreativa samarbetet. Uppsatsen undersöker om

ensamma kreatörens arbetssätt. Sammanfattningsvis vill vi undersöka
kombinationen av de två begreppen kreativitet och samarbete och dessas inverkan
på en arbetsprocess inom kreativt skapande..
Elektronisk motorstyrning för ottomotorer
The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.
Termisk Vattenpump

The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.
Ljuddesign för bildkonst
Detta arbete beskriver hur man ljudlägger konstfilm, hur man plockar upp ljud
vid inspelningsplatsen och hur man ställer ut en flerkanalig ljudläggning av en
konstfilm. Detta är de tre huvuddelarna i detta kandidatarbete, och dessa
kommer att förklaras med hjälp av mitt eget tillvägagångssätt, tillsammans med
problem jag stött på och hur jag löst dem. Reflektionen redogör även för
betydelsen av kommunikation mellan konstnär och tekniker och hur man som
