Klassifikationssystem på webben: Traditionella och nya

The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.

Culpa in contrahendo och formkravet i JB : De lege lata och de lege ferenda

Along with the development of technology, the cross-border trade is increasing and therefore there is a need for greater consumer protection. A good consumer protection creates a feeling of safety for the consumer and that by itself may help to increase cross-border trade. This is one of the reasons for why the EU has established regulatory framework for electronic commerce, for example the Directive2000/31/EC. The direc-tive strives to create a similar law for electronic commerce within the European Union. This paper?s main purpose is to ensure that the directive is implemented properly in Swedish law, and if there are other possible ways to achieve the objective, other than the ones that the Swedish legislator has chosen.

Användaren och den elektroniska referenstjänsten

The purpose of this master?s thesis is to study an electronic reference service from a user perspective. By qualitative interviews with eight students the thesis examines their information behaviour, why and when they use the service, the user?s experiences of the service and the communication with the librarian. The users have all used the Swedish electronic reference service Fråga biblioteket ? Forskningsbibliotek.

Electronic Data Interchange : för mindre företag

Det här arbetet behandlar ämnet EDI (Electronic Data Interchange). EDI är en teknik som gör det möjligt för företag att utbyta affärsinformation elektroniskt, i stället för att använda den traditionella pappershanteringen. EDI ersätter normala pappersdokument med elektroniska filer, som gör det möjligt för olika företags datorsystem som är sammankopplade, att kommunicera med varandra utan mänsklig inblandning.I arbetet har en undersökning genomförts med utgångspunkt på EDI och mindre företag. Anledningen till att jag inriktat mig på mindre företag är för att jag anser att dessa har en annan syn på investeringar och satsningar på ny teknik än vad de stora företagen har. De frågeställningar som jag har undersökt är hur stor utbredningen av EDI-användningen är bland mindre företag, anledningar till att mindre företag tvekar med att införa EDI.

PSQS ? Power Supply Quality Simulator

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

Utvärdering av datoranvändning i primärvården med särskilt fokus på remisshantering

The aim of the thesis is to present a study of what works well and what does not work so well in today?s use of computers in primary care with a special focus on the use of computers in the management of referrals for consultation. In May 2009 a module for electronic consultation referrals was introduced in the computer system Cosmic at the University Hospital in Uppsala. Previously, the primary care units had to use two different systems for management of referrals. Referrals sent internally within primary care have been sent electronically while referrals to the University Hospital or other external units were sent on paper.

Rekommendationer för införande av public key infrastructure

The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.

Automatisk genreklassifikation : en experimentell studie

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

Tolv böcker i datorn ? bättre än en i handen?

This thesis studies how readers of the electronic book (the e-book) use and perceive the electronic medium as a carrier of fiction. In this study it is assumed that fiction is mostly read in printed format. Therefore it is interesting to ask why some readers choose to read on screen. As there are all too few studies conducted on how readers perceive and use the e-book as a medium, this study aims to enrich an undeveloped research area. The study is based upon a qualitative questionnaire.

Avfyrnings-/relälåda

This is a report of our examination project in electronics carried out for Bofors Test Center in Karlskoga. The task was to construct an electronic devise for starting up different kinds of measuring systems in exact time during test sequences. The modules that are used today are old and unreliable. Our goal was to construct a prototype, which later on is supposed to be developed into a useful system..

40 år av kursplaner : en kartläggning av engelskämnets utveckling i den svenska grundskolan 1962-2000

Det övergripande syftet med detta arbete var att undersöka hur kursplanen för engelska i grundskolan har förändrats under perioden 1962 till 2000. Undersökningen syftar således till att kartlägga kursplanernas utveckling av engelskämnet ur ett historiskt perspektiv. Denna uppsats har med utgångspunkt från en komparativ textanalysmetod undersökt hur kursplanerna i läroplanerna från 1962, 1969, 1980, 1994 och kursplaner 2000, den reviderade kursplanen från 1994 skiljer sig från varandra rörande beskrivningarna för de grundläggande kunskapsområdena ?höra?, ?tala?, ?läsa?, ?skriva?. Centralt för analysen har varit att försöka klargöra den kunskapssyn som framträder i kursplanerna och de språkvetenskapliga teorier som influerat deras utformning.

Förutsättningar och hinder för att minska elektronikavfall : En studie över hur WEEE-direktivet påverkar Sveriges förebyggande åtgärder mot elektronikavfall

To meet the growing amount of waste from electronic and electrical equipment (WEEE) EU developed, year 2002, a directive (2002/96/EG) with the objective to govern the management and reduce the amount of WEEE. The directive is based on producer responsibility which makes the producer responsible for collection and dispose of WEEE. In 2012 a new revised directive (2012/19/EU), with tougher collection targets, was developed. Both the old and the new directive states that the approach to tackle WEEE should be prioritized in order of prevention, reuse and then recycling. Hitherto the amounts of WEEE has increased every year, making it relevant to examine which type of preventive measures the directive contains and how effective they are.

Hur Value Propositions formas genom interaktion mellan aktörer i nätverk : En studie av styrketräningsutövare och kosttillskottsprodukter

Idag marknadsförs mängder av produkter vars funktionella värde, av olika anledningar, är svårt för konsumenterna att konkret utvärdera. De Value Propositions som tillverkare och återförsäljare av dessa produkter förmedlar skiljer sig potentiellt från de Value Propositions som konsumenterna faktiskt använder sig av vid sina köpbeslut. Dessa produkters natur medför att konsumenterna tar aktörer, andra än producenterna och återförsäljarna, till sin hjälp för att vidareutveckla ursprungligt Value Proposition. Denna process utgörs av interaktion med exempelvis andra konsumenter i samma fysiska och/eller virtuella sociala nätverk. Nätverket blir då ett system för utformning och vidareutveckling av Value Propositions.

Oljudens musik : En revolution i kompositionsteknik?

Noise music is created around sounds not often welcome in a musical context. Since the birth of electronic music in the 1950s a new perspective on composing has emerged. In electronic music, sounds and their timbre are as much important as melody, harmony and rhythm. This composing perspective is not often observed. Therefore I have examined a musical genre that stretches the boundaries of what we consider music, sound, noise, beautiful and terrible.
