In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Anva?ndandet av internet i mobiltelefonen har o?kat drastiskt de senaste a?ren och detta fenomen inneba?r att ma?nniskor har tillga?ng till internet i sto?rre utstra?ckning a?n fo?rut. De svenska bankerna har tagit tillvara pa? denna trend genom att utveckla mobila bankapplikationer da?r de erbjuder sina kunder mo?jligheten att utfo?ra banka?renden med hja?lp av mobiltelefonen. A?ven om fo?rdelarna med denna tillga?ng a?r ma?nga, finns det a?nda? vissa nackdelar.

The objective of this study has been to examine which significant values are of importance in the telecom sector today, and in a continuing perspective yet to be. To ensure the factors of relevance in the study, we have identified three purposes: - Our first purpose is to clarify the eminent values in the competitive market of the mobile phone operators today, and the reason for its importance.- The second purpose is to understand the function of the brand regarding to value creation and loyalty in the sector of mobile phone operators.- The third purpose is to explore the potential approaches for mobile phone operators to increase value.In this study, our approach has been a qualitative methodology by conducting seven interviews with respondents related to the telecommunication sector.As a result of the process, we find the need to divide the concept of value into two dimensions, which we entitle organizational related values and customer related values. We have found the values related to the characteristics of the market in aspects of its infrastructural features but also in regards to the homogenous core service.Our findings in the empirical data with support to our theoretical frame of reference, is the current highly important organizational related value of constant high result quality (well-functional technological aspect), and the value enhancer by a low price; the strategy of bundling also results in higher value. This result in customer related values that perceives as safeness, availableness and convenience. The brands are a significant source of customer related values with identity value, image value and assuredness. A continued advancement in process quality and individualization will imply greater customer related values of closeness, freedom and flexibility. .

Mobiway AB är ett Sundsvallsbaserat företag som har utvecklat en tjänst föradministrering och bevakning av elektroniska parkeringsbiljetter. De vill nuexpandera sin verksamhet och skapa en egen parkeringstjänst ? en elektroniskparkeringsskiva. Mitt uppdrag har varit att utveckla och utvärdera enelektronisk parkeringsskiva för mobila enheter byggd i jQuery mobile. För attskapa en så användarvänlig och smidig sida som möjligt kommer alltinformationsutbyte att ske med AJAX kommunikation mot en RESTwebbtjänst.Projektet består av utveckling och utvärdering av en mobilwebbklient, en affärslogik byggd som en REST webbtjänst, en databas för attlagra all information samt en kundtjänst för att administrera tjänsten.Utvecklingen kommer att ske med en agil utvecklingsmetod.

Utvecklingen på webben går snabbt framåt och webbapplikationerna blir bara mer avancerade. Samtidigt så har de mobila webbläsarna utvecklats i en snabb takt. Dock skiljer det fortfarande mycket mellan en mobil webbläsare och en vanlig webbläsare, samt att man integrerar med en mobiltelefon på ett annat sätt än vad man gör med en dator. Detta examensarbete undersöker om det är möjligt att skapa avancerade webbapplikationer som, genom att utnyttja de senaste webbteknologierna, kan ersätta vanliga mobilapplikationer.Undersökningen genomförs genom att skapa en lättviktsvariant av en telefonapplikation, Mobile Documents till Symbian S60, som är en applikation som hanterar dokument, mejl och bilagor.Utvecklingen sker till största del i Google Web Toolkit och tekniker så som AJAX och Comet används. Eftersom antalet olika sorters telefoner med tryckskärm är väldigt stort så kommer undersökningen att rikta sig mot ett fåtal telefoner som kör webbläsarna Mobile Safari, microB och Android Browser.Slutsatserna av rapporten är att JavaScript-stödet hos dagens webbläsare är stort nog till att köra avancerade webbapplikationer.

This thesis examines the democracy theories that can be found in the internet websites of Region Skåne and Stockholm county council. Within the framework of deliberative democracy, participatory democracy and electoral democracy, the author tries to distinguish democratic aspects by empirically studying these websites and their communicative effect on the internet users.This research shows that Region Skåne is slightly better in implementing democratic aspects at their home page, which is probably due to an active work with these issues carried out by the politicians and the report on the democratic development from 2004. However, a great deal of work regarding democracy and the possibility of civic participation in the decision- making process is still to be done.The problems and challenges in using internet as a democratic tool shows that citizens run a risk of being neglected, due to their uneven participation in using internet in daily life. The conclusion of this thesis is that the politicians have to make an active choice in deciding to what extent the internet is allowed to be used when it comes to developing democracy. This work has to be done in cooperation with political scientists and IT experts, in order to assure a correct democratic model..

In this project we have explored digital tools for service management on the bicycle paths of Malmö. This was done through the participation of citizens in order to attempt to discern how such interactions can be eased using a mobile app, as well as how this app can be designed in order to appear trustworthy with user friendly interactions. We have explored this field by using goal-oriented design through interviews, prototyping and user tests. We have created a digital prototype as a possible solution for how the interactions can be done. Throughout the process interviews were held and user tests with selected members of the user group. To explore the concepts we have used paper prototypes in order to establish the design and then defining the interactions with the help of a digital prototype. Finally we have concluded that a general app for bikers in the city would be functional and that a longer study in the effects of such an app would be interesting as a continuation of this work..

The outset of this thesis is to raise questions on how we design for the mobile context and the capabilities of smartphones. Not only the presentation but also the use of input and interaction between a service and a user.This work evolves around sign up forms and answers the question: How does the sign up process affect the holistic perspective of a digital service regarding usability and user experience? This thesis consists of a case studies, and design experiments conducted on Twitter, Instagram and Randos sign up processes to explore if and how the usability, and the user experience could be affected and im- proved.This concluded some important aspects to be considered when designing sign up forms for a digital service.The usability, and the user experience is not only affected by user interaction, and the choice of input method but it?s also affected by which data the service is requesting, and more important; if that data is motivated to request by the service..

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

The aim: to study women?s attitudes to breastfeeding and their perceived difficulties with breastfeeding expressed on parent oriented websites on the Internet. Method: Data consisting of users posts corresponding to the aim of the study were collected from two parent oriented websites on the Internet.

The aim of this study is to examine reading on the MobileReadforums. The term ?to read? is extended to also cover bookcollection and usage of new technology such as mobile readerunits.A catalyst for reading on mobile reader units seem to be the needto always have access to the personal e-book collection. Apartfrom being a source for reading the collection of e-books alsoserves the purpose of extending the members self-esteem.A large portion of the activities on the MobileRead forum isaimed at making new technology comprehensible with the help ofprotocols to determine the usage of that technology. The processof making protocols also seem to be another way for the membersto extend their self-esteem.Traditional libraries are mainly seen as one of many sources for ebooks.Librarians are mostly perceived as being service mindedbut lacking in e-book knowledge.There is also a risk for miscommunication as the library hasdeveloped other protocols that defines an e-book and how itshould be used.This study is a qualitative analysis based on forum posts collectedfrom the MobileRead forum..
