Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

The students participating in my development work will work with a process book for handicraft studies. In the beginning of their studies, the students need practical knowledge about the development of the profession itself, but they also need to be challenged and learn how to solve problems on their own which will help them gain a deeper knowledge of the subject.    I focus on open questions to create a process with the students. This process is created when working with Solution-Focused-Education. Through ?assessment for learning? we can help the students to improve their self-assessment and understanding of the learning process.

In process oriented organizations, it is important to have well-functioning work processes tosupport the work being performed. In order to accomplish this, the organization has to makecertain decisions regarding the design and usage of the processes. This master thesis is based ona case study of a work process that is being used for the industrialization of products at Ericssonin Katrineholm. The aim of the study is twofold. One aim is to improve the studied process byidentifying improvement opportunities and carrying out the required adjustments.

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

As the environmental requirements on businesses increase from various stakeholders, the incentives for businesses to work more with environmental issues also increase. Historically, the requirements were focusing on companies with direct emissions from operations. Lately, the environmental impacts that occur indirectly as results of corporate activities have become more topical. Companies and organizations that mainly offer services often have a greater indirect than direct environmental impact. This is because they are affecting third parties, which in turn have a direct environmental impact.

AbstractThis bachelor thesis has been assigned by the company ACG Nyström, Borås. ACG Nyström is working in cooperation with a Swiss company named Jentschmann AG. Jentschmann is a manufacturer of ultra sonic welding machines which ACG Nyström is marketing in Scandinavia and the Baltic States. On behalf of Jentschmann AG the company has the aim to introduce the ultra sonic welding technique to new companies.The aim of this thesis is to compare traditional sewing machines with ultra sonic welding machines within two textile areas, protective clothing and outdoor living.Two investigative questions have been formulated for this purpose: what are the differences between a sewing machine and an ultra sonic welding machine? Is it possible to replace the sewing technology with ultra sonic welding? These stand as guidance for this paper.To gather knowledge interviews, literature studies, and tests on two different ultra sonic welding machines were performed.

Today there is a large consensus about the importance of Swedish schools providingconditions enabling students to develop the ability to manage and learn through information technologies (IT). The goal of this study was to describe and examine how national education goals for the use of IT transformed into municipal IT-strategies for the school. A content analysis was conducted of thirty-eight municipal IT-strategies collected from Swedish municipal websites on the Internet. The content in the municipal IT-strategies was compared with the content in both the Swedish education act and the national curriculum. The results showed that the content in the Swedish education act and the national curriculum in fact was translated into municipal IT strategies, but that the range of strategies concerning technology, pedagogy and content in relation to IT was broad.
