Design and Analysis of an All-optical Free-space Communication Link
Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.
Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med ånga
This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..

Utveckling av Innovativa Småskaliga Elförsörjningskoncept : - Minor Field Study i Namibia
A large part of the Namibian low income population lack access to grid distributed electricity. This mean they are effectively shut out from basic functions such as lighting, information technologies and hygienic food handling. Hence, finding ways of providing affordable off-grid electricity is an important, not to say critical, task.This master thesis is an innovation and concept development project that has been carried out in cooperation with organisations in Sweden and Namibia. The purpose of the project has been to (1) develop a concept for off-grid electricity supply in Namibia and (2) to gain a deeper knowledge within the area of innovation and product development for the Base of the Pyramid population, i.e. the poorest, but largest, socio-economic part of the global population.Essential in this project has been to acquire user understanding and to identify user needs to create a foundation for developing the concept.

Functional Requirements for Bibliographic Records : Viktiga frågeställningar och områden för FRBR
In this Bachelor's thesis the result from a Delphi study regarding FRBR, performed by Yin Zhang and Athena Salaba in 2007 and published in 2009 ? What is next for Functional Requirements for Bibliographic Records? A Delphi study ? is analyzed by qualitatively interviewing professionals active within the library and information science field in Sweden. The results are compared and possible deviations and adjustments are illuminated and discussed. The purpose of the thesis is to determine the topicality of the Delphi study in 2011 from a Swedish perspective. Conclusions made from the thesis shows that the main areas are still the same, but adjustments regarding the relative order of issues might be needed; primarily a shift of focus from theoretical to practical issues.

Digital marketing has been changing continuously and rapidly since the introduction of Web2.0 ten years ago (Lin, Li, Deng, & Lee, 2013). Companies are now engaging their users intheir digital marketing by providing with interactive contents in digital campaigns. The digitalcampaigns are getting more converge with SNS (social networking sites) in order to let the usershare the content with others and therefore the e-WOM (electronic word of mouth) helps thecompanies digital campaigns to be shared by more users (Moran, Muzellec, & Nolan, 2014).The interactive content in the digital campaigns have shown to provide for engaged users andtherefore leads to loyal users. The reason for this has its roots in the culture of consumptionthat has brought our everyday consumption to a whole new level where we no longer justconsumes a product, we are the brand (Davis, 2013).The study, Click here for solidarity, aims to explain the interactive phases and rhetorical elementsthat companies use to engage the user to interact with the content of the digital campaigns.The study is based on four digital campaigns in four different market areas in order to providewith an overall picture of how companies work with interactive and rhetorical elements.

?? man får vara lite uppfinnare på något sätt? - Om referenssamtalets problem och hinder med fokus på kommunikationssvårigheter
The purpose of this thesis is to study how some librarians working at a public library experience problems that can occur at the reference interview, slightly focusing on communication difficulties. Therefore I interviewed three librarians working at the reference desk on a daily basis. I chose to limit the study to public libraries and to the south of Sweden. My main question is: what difficulties can a librarian encounter during a reference interview and what can he/she do to treat these? In support of my main question I have three subordinated questions:What reasons can there be to a librarian not understanding a user?s information need?What methods are useful for a librarian to enhance the condition of the reference interview? What attitudes and qualities can be of use for the librarian at a difficult reference interview?For the collection of empirical data I chose to use semi-structured interviews.
