Webbsäkerhet och vanliga brister : kunskapsläget bland utvecklare

This bachelor thesis looks at developers knowledge about web security both regarding their own view on their knowledge and their actual knowledge about vulnerabilities and how you mitigate against them. Web developers knowledge regarding web security are becoming more and more important as more applications and services moves to the web and more and more items become connected to the internet. We are doing this by conducting a survey among developers that are currently studying in the field or are working in the field to get a grip on how the knowledge is regarding the most common security concepts. What we saw was that the result varies between the different concepts and many lack much of the knowledge in web security that is getting increasingly more important to have..

Skalkonstruktion : Med inriktning mot hållfasthet och dämpning av ljud

The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.

Tankar om demokrati, effektivitet och legitimitet -En idéanalys av debatten om EU:s framtid i två länder

In recent years the concern about the future of the European Union and itssupposed lack of democracy, efficiency and legitimacy has increased. Thisconcern has resulted in extensive debates and the establishment of a conventionwith the task to create a draft treaty for a European Constitution.The aim of this essay is to study how the three theoretical concepts,democracy, efficiency and legitimacy, have been described and used in the debateabout the future of the European Union. My main interest is to see how theseconcepts are described in a debate regarding a political system that goes beyondthe borders of the nation-state. I have made a comparative textual analysis of thedebates taken place in Sweden and Spain during a period of over two years. Ihave, for instance, found out that openness and clearness have a prominentposition as democratic values together with equality and justice (in Spain) and theinstitution of accountability (in Sweden).

Vetenskapsjournalistik i radio - Vad får vi veta? : En innehållsanalys av vetenskapsradions nyhetssändningar hösten 2004

AbstractPurpose/Aim: The aim of this essay is to paint a picture of science news reporting in the Swedish Public Service science programme, vetenskaps-radion. Key issues to be adressed are: What areas in science are prioritised? How much of the total broadcast time are devoted to each area? Are there any differences in reporting between weeks? How well does the swedish science radio match common interets? Are the news in the form of short ?soundbites? or are they more lengthy in-depth?Material/Method: Quantitative analysis of radio programmes. The variables used are based on the different major areas in natural sciences.Main results: This study shows that most broadcast time is devoted to news regarding biology and medicine and that the news rather are in the form of short snippets of news than more lengty in-depth stories. This is put in light of how journalistes tend to present news and that the subjects involved has to relate to peoples everyday lives.

Praxis och praktik i flerspråkiga tesaurer

A prerequisite of an international exchange of information is multilingual tools for information retrieval, such as the multilingual thesaurus. There is an ongoing discussion about the construction of, and the guidelines for, multilingual thesauri. In recent years the praxis as defined in ISO 5964 Guidelines for the establishment and development of multilingual thesauri 1985 has been the topic of a scientific discussion. It has been about how equivalence across languages is to be established when it comes to concepts, terms and relational structures. This masters thesis treats the praxis and practice of multilingual thesaurus construction.

Den ideologiska spegeln - en studie kring hur ideologisk-diskursiva ramar skapas inom ramen för ett politiskt parti

AbstractOne aim of this thesis, has been to explore how discursive frames are constructed, frames to relate to, compare with, and therefore be part in shaping political subjects. The other aim has been connected with a more empirical platform, where I wanted to discover how these frames are established and structured discursively within a political organization, among its members; in this case with a foucs on the Swedish social democracy and its former leader Olof Palme. The thesis starts with a theoretical presentation and discussion, where focus is on the concepts of ideology, discourse theory in the form of Laclau and Mouffe, and narrative theory. The concepts will be presented and discussed, and also related to the other concepts to see their theoretical potential, both ontologically and epistemologically. Finally the theoretical rudiment is linked and analyzed with the empirical material.

Barns språkutveckling i förskolan

AbstractThere is a lot of confusion when it comes to defining Special Education. An example of this appears here by a statement from Assarson (2007) "Special Education initiates a special pedagogy, but contains no innate sense of what is the special component in it" (p. 52, authors? translation). This study is an attempt to clarify the elements of the concept.

Den mångskiftande mångkulturalismen : En kritisk diskursanalys av mångkulturalism i bibliotekskontext utifrån ett intersektionellt etnicitetsperspektiv

The purpose of this thesis in Library and Information Science (LIS) is to examine concepts related to multiculturalism in Sweden. It aims to look beyond the rhetorical construction of these concepts, in an attempt to clarify the actual purpose of commonly emphasizing the importance of mulicultural library services. Norman Fairclough's critical discourse analysis (CDA) as well as theories on ethnicity and intersectionality constitute the theoretical frame. The material consists of selected anthologies, handbooks and articles in Biblioteksbladet from 1974?2014, as well as a small case study.

Volymmätare för tall- och grankott

This thesis describes the planning and development of a volume meter of pine and spruce cones. The product was designed and developed for Stigsjö Skog och Frö AB in Härnösand. It was developed taking into account a number of requirements set by the supervisor David Zetterlund. The main requirements were that the volume measurement would be fast and give accurate results. These are two requirements that are missing in today's volume measuring method which is very problematic for the company.The plant was visited several times in Härnösand, mainly to discuss the generated concepts with the supervisor and perform tests on the prototype.

Mobiltelefon utformad med EcoDesign

The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.

Religion och vetenskap : En studie om tematiken religion och vetenskap samt dess gränsländer i gymnasieläromedel

The following essay aims to determine what textbooks and teaching media educators in the county of Västerbotten use when teaching the relation between religion and science. Based on educational science theory and through analyzes of factual texts, the teaching materials was examined to determine how much focus they put on the thematic of religion and science. The result shows how the different teaching materials affect this thematic differently. The main conclusion is therefore that students in Sweden could, depending on the teaching materials used in their education, be taught by different standards to reach the same requirements..

Naturvetenskap i grundskolans lägre åldrar : Om lärares förhållningssätt gentemot ämnet

This investigation is about how teachers in school can motivate and create interest for science among younger children. Teachers were interviewed about attitudes to their subject and how this affects their lessons.I have also tried to find out, both by interviewes but also by studying litterature, what the most important thing is to teach in science, which knowledge is necessarry in the future and why.My result indicates that teachers find science both interesting and important but at the same time they also think it is a difficult subject to teach even if they are educated. Both the litterature and the teachers in my study agree that knowledge in science gives us a chance to ask questions, take stands and solve problems and that this knowledge is important for us in our future..
