Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

The purpose of this study is to investigate how important computers are for text production in upper secondary school level, and to find out what attitudes some students have towards computers in writing classes. I have let 44 students in the Swedish gymnasium course Swedish B write an argumentative essay. Half of the group wrote using paper and pencil, and the other half used computers. The essays were graded, and the language and length of the texts were analyzed. The students also filled in a questionnaire with questions on computer aided writing classes.The results showed that the texts that were written with computers contained a significant larger amount of words and fewer spelling mistakes.

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

During my education I have frequently noticed that pupils do not like science or find it hard and dull. The purpose with this investigation is to find out how pupils experience their science education and if they can understand the arguments for studying the subject at school.I have made a questionnaire study among pupils in grade 8 and 9. After analyzing their answers I have interviewed some of the pupils to get answers on further questions.The investigation resulted in conclusion that pupils have hard to connect their science-education to their everyday lives. The most important element in forming the pupil?s opinions about science is their relation to the teacher and how the lessons are set-up.The following questions will be answered in this paper:Do pupils understand why they have science at school?Can the pupils see the use of scientific knowledge in their everyday life?How do pupils look upon their science education?.

The purpose of this paper is to investigate how a small company manages its information, primarily the organization of digital documents. The two dominating themes are classification and information politics, the former in the context of a corporate environment and the latter to help us to describe the situation at the company. The method used has involved observation of the company's current computer network structure and also interviews with six employees at different levels in various departments at the company. The result of our investigation has been the realization that, although logical structure is important when organizing documents in a digital environment, it is also necessary to have rules regarding its implementation..

Dataspelsproblematik är ett eskalerande problem som har visat sig påverka många unga människors utveckling och välbefinnande. Syftet med denna studie var därför att undersöka ungas dataspelsproblematik, vilka konsekvenser ett överdrivet dataspelande medför samt vilken behandling som ges till unga med dataspelsproblematik. Empirin erhölls genom kvalitativa intervjuer med professionella som arbetar med denna typ av problematik vid verksamheterna Game Over och Theory in Action. Resultatet visade att dataspelsproblematik idag inte har en bestämd definition och att det är ett problem som inte är tillräckligt uppmärksammat. Synen på orsaker till dataspelsproblematik hos unga är komplext då det kan tänkas bero på många olika faktorer.

Recent papers and bills from the Swedish Government deal with the possibilities  of giving all Swedish citizens the possibility of their own creative actlvities in the cultural sector. This work is about where such actlvities shall be placed in order to make them obtainable  for all. As an example of creative work this work takes computer-based music-making. At the public library in Odense, Denmark there is a weil functioning sound workshop where the public gets the opportunity of making music with some assistance from the staff. This work shows  that also in Sweden  the public libraries are the most suitable  institutions  for placing studies for computer-based music-making  for the public depending  on the public libraries'  traditions in adult education.

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

This study was built on the concept of Emotional Intelligence (EI) as an ability with four branches, to effectively: (1) perceive (2) reason (3) understand and (4) manage emotions. By closely studying the four processes of EI through eight semistructured interviews with psychologists, counselors, CBT-therapists and psychotherapists, a study of participants' stories from real practice was done and then analyzed and interpreted. The purpose of this study was to get the participants to describe and put words on practical experiences that occur with clients that correspond to the four domains that define the concept of EI according to Mayer et al. (2008) and find out about if their way of "doing" EI gets trained and developed after several years of professional activity. The results shows that the practitioners used all four branches of EI in dialog with the client, both intra- and interpersonal.

Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.

This essay describes the philosophy of science that Thomas Kuhn puts forth in his work The Structure of Scientific Revolutions. The question is, does his description of the scientific paradigm work as well today as in the examples he gave in the book?The conclusion is that there are certain factors that make for a number of differences between science today and, for example in the seventeenth century. There is also a growing theory or vision of a post normal science laid developed by among others Jerome Ravetz. This theory or vision is an idea of a science close to peer-communities and fast as well as critical decisions involving opposite values..

Denna uppsats avser att belysa frågan varför prototyper är ett viktigt verktyg i en utvecklingsprocess av ett mobilt system. Fördelar och nackdelar som verktyget kan innebära behandlas och olika tillvägagångssätt beskrivs. Arbetet med detta baseras i ett praktiskt utvecklingsprojekt på IT-kunsultföretaget Citerus. Projektuppgiften var där att genom en informationflödesanalys definiera olika flaskhalsar i informationsflödet på olika hotell för att sedan föreslå ett effektiviserande system. Projektet koncentrerades vidare på städpersonalen och deras arbete. Utifrån fortsatta studier föreslogs ett mobilt system som ger städpersonalen information för att lättare och effektivare göra sitt jobb. I flera olika forskningsdiscipliner som berör design och systemutveckling förespråkas ett utvecklingssätt med hjälp av prototyper.

This essay is investigating what type of sources we trust, depending on how the information in these sources is created and provided. To exemplify, the sources Wikipedia and Nationalencyklopedin (the Swedish National Encyclopedia) were used, each one representing different approaches. The first is a representation of the collective intelligence, where anyone can contribute with their knowledge to the public ? freedom under responsibility. The latter represents peer-reviewed knowledge, desirable enough to have people paying for it? true and unaffected.Based on theories of source criticism, collective intelligence, expertise and the different generations of digital natives and digital immigrants, two focus groups were conducted and analysed.
